Temu and Shein at the moment they get rid, the Big Tech breathe

by

After the storm, some calm. At least, temporary. The feared tariffs from the United States to imports from China products They threatened The world economy, but in recent days we have seen the Government of Donald Trump has paused these measures. In fact, he has just done the same with the measures that especially affected Temu and Shein. What happened. Donald Trump has applied A remarkable cut to tariffs that apply to small value packages that arrive from China and Hong Kong to the United States. Thus, the new tariffs on those packages of up to $ 800 of value go from 120% to 54%. The reduction is important, but tariffs continue to impose remarkable rates for this type of products. Temu and Shein breathe (a little). Chinese online trade giants such as Temu or Shein have been benefiting from The exemption called “Minimis” To be able to send low -cost products directly to consumers in the United States without paying import rates. That rule It was canceled by the Trump administration a few days ago, and that caused A domino effect which affected the Big Tech of the US. WOMAN FOR META AND GOOGLE. The decision also relaxes the pressure on Meta and Google, which were great beneficiaries of this commercial exchange. Temu and Shein They sold big in the US Thanks to the exemption of Minimis, but to achieve it they spent true fortunes in advertising that hired giants such as Meta and Google. By deactivating that exemption, advertising income immediately They diverse. These ads are expected to reactivate that advertising expense in the Big Tech. But be careful. Although the situation improves for Temu and Shein, the pause has a small print. Trump changed the minimis rule for a flat rate of $ 100 per package with value of less than $ 800, and that flat rate would amount to $ 200 in June. These rates are maintained despite the 90 -day truce agreement for other tariffs and make it sell directly from China to consumers (very) expensive for Temu or Shein. Temu dodges the measures selling from the US. To avoid the application of these tariffs as far as possible, Temu began to fill gigantic warehouses in the United States of their products to be able to send their “locally” products before they were affected by tariffs. That measure is temporary, because those warehouses will end up needing to fill again and it will be then when they will face these new tariffs. Plan B: No direct sale. Precisely at that time is when Temu has an escape with this announcement of the Trump administration. With the direct sale of products to consumers punished for tariffs and flat rates, the solution is not to sell directly, but fill their warehouses with large orders (no packages below $ 800) and then serve consumers locally. In this way “only” the new reduced tariffs (30%) apply and not those of 54% that affect these value packages of less than $ 800. It is certainly a respite for businesses like Temu, which have the United States as their large sales market. Trump continues to back. The month of April we lived a unique burst of ads in which the US decided to raise their tariffs to China and the Asian giant responded with equivalent climbs. The situation on April 11 reached absurd ends: US tariffs to Chinese imports reached 145%, and China’s to US products to 125%. Neither seemed to move token, but Trump ended up yielding Any was he who started hostilities. Yesterday both countries announced a 115% reduction in these reciprocal tariffs, which has been a real relief for the world economy. Image | Alain G.

This hacker began to collaborate with the secret service after being arrested. What nobody knew is that he kept stealing big

by

In the summer of 2003, a routine investigation for a series of robberies in Manhattan led to unexpected finding. An undercover agent of the New York Police Department followed a young man who behaved suspiciously and observed him for several minutes in the lobby of an ATM. I was extracting money with one card after another, All of them falsifiedtaking advantage of the day change to overcome the daily limits of withdrawal. That scene was just the tip of the iceberg of a much more complex criminal network, as detailed years later The New York Times. That young man was called Albert Gonzalez, although on the Internet he preferred to hide After alias as “Soupnazi”. What he did was known in the criminal forums as “CASHING OUT“: Use cloned cards to get cash before banks could react. His detention opened the door to an unprecedented operation. The agents discovered that he stored millions of card numbers on their computer and that, in addition to executing fraud, it had detailed knowledge about cybercrime techniques. Gonzalez was not any criminal The role of this individual in the community of cyber criminals was highlighted: he exercised as a moderator in Shadowcrew, a forum that centralized the exchange of stolen banking data, tools for falsifying cards and advice to exploit vulnerabilities in the financial system. When it was arrested, As NPR points out, He chose to collaborate with the authoritieswhich allowed him to dodge an immediate conviction and become an informant of the Electronic Crimes Unit of the Secret Service. For months, he collaborated in an undercover operation within Shadowcrew and facilitated an international maneuver that culminated in October 2004 with 28 arrested in several countries. The operation, Baptized as Firewallbecame a reference for cybercrime investigations. But the story did not end there. While working for the Government, Gonzalez parallelly built a much more ambitious criminal network. Using various techniques, it accessed internal systems of large American clothing and distribution chains such as TJX (owner of TJ Maxx and Marshalls), Offemax (stationery and office material) or DSW (footwear). Justice data indicate that he and his collaborators stole more than 40 million numbers of credit and debit cards. These intrusions included the installation of “sniffer” programs capable of capturing in real time the data of the cards used in point of sale. The numbers were subsequently encoded on virgin cards and used to remove cash in ATMs. Arrested in the middle of the Firewall operation The final jump came with the use of the SQL injection technique, which allowed to remotely access databases from web forms. With her, Gonzalez and her team They managed to infiltrate Companies servers such as Heartland Payment Systems, one of the main payments processors in the United States. The attack committed the data of millions of transactionsaffecting more than 250 financial entities, and went down in history as the greatest robbery of cards recorded until then. This was detailed by the United States Department of Justice in an official statement issued in 2009. Chains such as 7-Eleven (convenience stores) and Hannaford Brothers (supermarkets) were also affected. Albert González While collaborating with the day authorities, at night he continued to send stolen databases through contacts in Eastern Europe. He used ghost companies, opaque transfer systems and mules to bleach millions. He even sold committed information to hackers who were being investigated, thus feeding new lines of accusation. Finally, after a series of key arrests and the tracking of an email account linked to their old alias, the agents closed the fence. He was arrested in 2008 at a Hotel in Miami. Shortly after, he led researchers to a bidon buried at their parents’ house With more than one million dollars in cash. American justice condemned in 2010 to 20 years and one day in prison for crimes of conspiracy, computer fraud, aggravated identity theft and money laundering. It also imposed two fines of $ 25,000 each, which total a total of $ 50,000, and three years of freedom guarded. The ruling grouped the causes presented in Massachusetts, New Jersey and New York. Albert Gonzalez, who, According to Podcast Malicious Life and The New York Timeshad come to hack NASA being a teenager and had caught the attention of the FBI, ended up becoming one of the greatest traitors of the hacker ecosystem and a key figure to understand the evolution of cybercrime in the era of electronic commerce. On September 19, 2023, he ceased to be in custody of the Federal Bureau of Prisons, As stated in the records of the American prison system with the number 25702-050. Since then, his trail has become discreet, as if he tried to definitely move away from his past.

Twitch and other big have just joined their crusade

by

LaLiga announced on Wednesday through a press release the signing of new collaboration agreements with Twitch, Vercel, Scaleway and Gcore. The objective is clear: deactivate any illegal activity detected in their respective technological infrastructure. These alliances reinforce an already active strategy with CDN77 and Akamai, actors with which the organization had been working on this same line. Reinforcement of its antipiratría strategy. In recent months, LaLiga has intensified His fight against unauthorized retransmission of parties. One of the methods used has been the blockade of IP addresses, a measure that, sometimes, has generated controversy by also affect services outside the illegal activity that is intended to combat. The new agreements go in the same address: the companies involved must act rapidly before any illegal issuance detected. The fixed commitment establishes an average response period of 15 minutes from the notification, although from LaLiga they ensure that the objective is to reduce that margin as much as possible to limit to the minimum the dissemination of the content in unofficial channels. No collateral damage. The organization also wants to prevent situations such as those mentioned above, in which indiscriminate blockages that affected legitimate services were produced. The goal is now to achieve a more precise intervention, which acts directly on illegal emission spotlights without generating side effects. Commitment to the audiovisual industry. From LaLiga they explain that these agreements are framed within effective programs for the protection of intellectual property rights. The signatory companies, they point out, demonstrate “a firm commitment to the audiovisual industry and with their own clients to offer them an experience that minimizes possible impacts, without giving up the protection of intellectual property, to security and the privacy of user data.” A technological ecosystem involved. Twitch, the well -known streaming platform owned by Amazon; Vercel, specialized in display of web applications; Scaleway, European cloud services provider; and Gcore, multinational that offers computing solutions, Edge Computing, CDN, accommodation and safety, add to this technological offensive. Together with CDN77 and Akamai, they form a diverse but aligned ecosystem with a common goal: to combat the illegal distribution of sports content through collaboration with technological intermediaries. We will have to wait to know if this movement will give the expected results. Images | LaLiga In Xataka | How to claim if you are seeing yourself affected by indiscriminate laliga blockages

China’s big problem with chips is its difficulty to go beyond 7 Nm. Huawei’s new megaphabic confirms it

by

China is doing everything in your hand to achieve total independence of its semiconductor industry. The commercial and technological war that sustains with the US prevents the country of Xi Jinping access to the manufacturing equipment of Most advanced integrated circuits that produces The Dutch Company ASML. And this in practice does not allow Chinese manufacturers, such as SMIC or Hua Hong Semiconductor, produce integrated avant -garde circuits easily. In the previous paragraph I have used the adverb “easily” intentionally because, in reality, China is manufacturing avant -garde semiconductors. They are doing it At least SMIC and Huawei using, as we have explained in other articles, a lithography technique known as Multiple patterning. This strategy in broad strokes consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. His problem is that he usually has an upward impact on the cost of chips and the decline in production capacity, although it works. In fact, the most advanced chips we can find in the last smartphones and hardware for artificial intelligence (IA) more sophisticated in Huawei have been manufactured using the technique of Multiple patterning with the purpose of reaching 7 Nm. However, presumably this Chinese company will produce Your new GPU for the Ascend 920 During the second half of 2025 using 6 Nm integration technology. Satellite images show the huge complex that Huawei is building A little over a year ago, in February 2024, the newspaper Financial Times said having had access to the statements of two experts who defended that SMIC was finalizing the refinement of their semiconductor manufacturing processes in their deep ultraviolet machines (UVP). Its purpose, according to this source, was to have the necessary technology to manufacture Integrated 5 nm circuits Massively before the year 2024. For SMIC and its clients, among which Huawei is, this would be a very important achievement. Huawei is trying to develop its own integration technology to go beyond 6 and 7 nm However, Huawei’s 5 NM socates have not yet appeared. The chip Kirin 9010 which has happened to the 9000S model is also being manufactured in the 7 NM SMIC node using The technique of Multiple patterning. We can find this soc, for example, in the new triple folding of Huawei, the Mate XT Ultimate Designwhich we tried during the latest edition of the Mobile World Congress in Barcelona. Anyway, we can be sure that Huawei is trying to develop its own integration technology to go beyond 6 and 7 nm. In addition, it has the support of the Chinese government. In fact, Financial Times He has achieved photographs taken from a satellite in which it is possible to see a titanic manufacturing complex of integrated avant -garde circuits that Huawei is building in Shenzhen. It is meritorious that a single company is trying to develop all the links in the semiconductor supply chain and AI, As Dylan Patel arguesthe founder of the semi -health consultant, but There is a problem. And is that according to Eleanor Olcottthe Financial Times correspondent in China expert in technology, this megaplant of chips production aspires to manufacture integrated 7 nm circuits destined for smartphones and hardware for Huawei. If this information is confirmed, it will be evident that this company is still anchored at 7 Nm, although it is important that we do not overlook that this semiconductor production plant will presumably belong to Huawei. Until now, its 7 Nm chips were manufactured by SMIC, but it seems that in a short time this company will have the ability to produce its own avant -garde circuits. It is only a matter of time that finally the barrier of the 6 and 7 nm is shot down.

Temu has been an advertising reef for years for the US Big Tech. That ended

by

In February 2024, the 58th edition of the Super Bowl was held, and during the break a very special announcement was issued. It was titled ‘Shop Like A Billionaire‘(‘ Buy as if you were a billionaire ‘) and published it Temuthe Chinese e -commerce giant. That turned out to be a swan song more than anything else, because this Chinese company (along with others like Shein) now has a very complicated future in the United States. Temu’s advertising expenditure on Big Tech collapses. As revealed In The New York Timesin the two -week period that began on March 31, Temu spent 31% less on Facebook advertising on Facebook, Instagram, Tiktok, Snap, X and YouTube of what did it on average on those platforms in the previous 30 days. The data are from the Consultant Sensor Tower, who also stressed that Shein also lowered her advertising investment: 19% those two weeks compared to the average in recent periods. Temu and Shein spent barbarity. Both companies were two of the large sources of advertising of the US Big Tech. According to The Wall Street JournalTemu invested 2,000 million dollars in advertising in goal in 2023, and was also one of the great advertisers in Google. In The New York Times they cited an equally striking estimate: according to Bernstein Research data, Temu spent 3,000 million dollars in marketing in 2023. Picture drop. But the panorama has changed radically. On April 5 Temu represented 19% of all ads published in Google Shopping in the US, but that figure fell to 0% a week later. Shein went from 20% to early 0% on April 16, according to data from the Tinuiti consultant. Apps fall into rankings. So far the mobile apps of Temu and Shein used to be among the 10 most downloaded in the United States. Now his popularity is falling, and they have left that top 10. Target warns. Susan Li, CFO of Meta, said in a recent conference with investors that some Chinese electronic commerce companies – without specifying – had reduced their advertising expenditure. Last year Chinese advertisers generated 18.4 billion dollars of target revenues. That represented 11% of the total and twice what was achieved in 2022. Pessimism is spread. Snap indicated after presenting financial results that “a subset of advertisers” had cut the advertising expenditure due to changes in shipments to the US. They did not want to provide estimates for the current quarter indicating that tariffs generated uncertainty. Google also showed its concern: its business director, Philipp Schindler, explained that changes with “obviously causing a slight setback to our advertising business in 2025”. The end of “of minimis“. Donald Trump, president of the United States, He signed in April an executive order for which the rule is put in the end of minimis. This exception has allowed for years that packages with value below $ 800 can enter the United States without paying taxes. It is a mechanism that platforms such as Shein or Temu have used to offer really competitive prices in their merchandise, but others such as Amazon, Etsy or Ebay have also benefited. Trump already warned. In February, the US government began its particular tariff war against China, imposing 10% tariffs on all types of Chinese merchandise. The end of the exception of minimis -carrying almost a century Activa – was actually an announced death, and its impact is huge, both in China and in the US. Trump momentarily suspended the exception then, but it is now when it is disabled indefinitely. Temu stop sending to the US. The Executive Order has caused Temu stop all shipments from China to US buyers. As they point out In CNBCa CNBC spokesman has indicated that all sales in that country are now managed by local sellers and are completed from the country itself, precisely to prevent tariffs from affecting those sales. Before the change, buyers tried to buy Temu products sent from China They faced each other At “import rates” between 130 and 150%, which caused many of those products to fold their price.

The US deserts have 1,200 GW solar for AI. The only problem is that Big Tech do not dare to use them

by

The Data centers They are the new 21st century factories. And like any factory, they need energy. A lot of energy. The main technology companies are building and operating Great data centers that allow offering services (video or Streaming video gamesfor example), but also where the different models of artificial intelligence. The problem is that They need more and morewhich translates into a growing energy demand. And although there are those who bet on the nuclear power and for the reactivation of fossil fuels, a study considers that the future is in the Solar energy outside the energy network. The problem is that, although the solution sounds great, it is not being applied. Hyperscalists. This is an important term. Technology companies that operate cloud computing infrastructures on a global scale are known as ‘hyperscalist’. Its data centers are crucial for the development of digital services, but also for the ‘big data’ and the advance of AI, and the term “hyperscalist” responds to those data centers can be scalar quickly and on demand. Climbing … how? Well, depending on the needs of that company and the fan that wants to cover, that scalability translates into more storage, a faster processing or a greater bandwidth on the network. Demand. The main players in this are Google, Microsoft, Meta or Amazon and although they have the capacity to expand their data centers, they are running with a huge problem: the amount of resources they consume. In large server centers, Water consumption It has always been a problem that companies have solved in different ways to be more responsible with the environmentbut the arrival of AI has been a revolution. Train and maintain these models consume a A large amount of energy resources And, apart from the water to dissipate the heat of the servers, a great energy capacity is needed. So much so, although there are companies Building more sustainable data centers At the structural level, energy demand is so brutal that They require coal and natural gas To meet demand. And some like Google either Goal they will use nuclear energy to feed your needs Energy out of the network. Contextualized the problem and seeing that these energy needs play against decarbonizationinvestigators of companies such as Stripe, Paces or Scale Microgrids have got to work to determine the best solution to feed those data centers in a sustainable way. His conclusion has been presented in a study in which they estimate that the total energy demand of the AI ​​for 2030 will range between 30 and 300 GW. In the case of the centers where AI training is carried out, that demand will be between 15 and 150 GW. It is a huge fan, but the solution they pose and that they consider optimal is the creation of micro -redes outside the network, fed by solar energy. According to them, systems with 44% solar energy are already competitive in costs compared to those based only on gas, and those that reach 90% renewable can be even more profitable than nuclear projects such as Three Mile Island of Microsoft. Green spots are green plots for a 90/10 stage Build where the sun glued. The advantage of this system is that its construction is fast because you do not have to reactivate a nuclear power plant. You are not tied to what the energy market demands, Geopolitical conflicts They do not leave you without supply, it is clean energy, buy solar panels is getting cheaper And, above all, it is easily scalable. If more energy is needed, it is as simple as adding more panels, but the most important thing in this equation is that they can build these centers in optimal places. Unlike servers centers, which do need to be close to the end user to offer a better service, the data centers in which the AI ​​training is carried out have geographical flexibility. This implies that they can install them in areas with optimal solar radiation and in places where the land is cheap. Optimal areas Optimal areas. In the study they have identified plots in the United States with a potential for up to 1,200 GW of solar energy outside the network, with gas support and an optimal area with large esplanades and radiation during a large percentage of the year. So, CaliforniaNevada, Arizona, New Mexico and the east of Texas They would be ideal places to house those data fueled data centers outside the network by 90%, with the remaining 10% backed by gas. Beyond this, the study points out that most of the appropriate land is private, so it can be purchased to build these facilities and that, in addition, many are within lands that would allow subsidies. If you start today, the construction bond would be between 12 and 24 months and everything seems positive, but it is not being done. If it is so good … why isn’t it? According to researchers, there are three issues that come into play. Two are closely related and have to do that this of AI training is a very recent phenomenon. The designers of the data centers have historically been skeptical when it comes to getting off the network because what they wanted was to enhance, above all, the reliability. They can’t stay a second without energy, go. Related to the historical tendency is inertia: it has never been done before, although current technology would allow to operate only with renewables (as some countries already do). And the third reason is the cost, $ 23 per MWh, specifically. The panels are increasingly affordablebut it is more expensive than not buying those panels -evidently. However, the researchers point out that this extra cost would be dampened by the Cost of emissions and compensation that would be avoided in the short term. Therefore, these solar micro -lands outside the network seem a quick way to feed large -scale data centers, but although technology is mature, it seems to spend time until … Read more

We have been looking for the definitive cure of allergies for years and we have not yet solved the big problem: understand them

by

The end of the rains and the arrival of good weather have, for many, a dark back: The allergies. Spring, and especially the months of May and June, brings us the pollen proliferationone of the most important allergens, the main cause of sneezing at this time of year. The most common way of treating this type of allergies is through antihistaminesdrugs aimed at blocking the effects of histaminea neurotransmitter that also plays an important role in immune system. Recall that allergies are nothing other than a reaction of our immune system to external substances that understands as dangerous and that are not really, allergens. Antihistamines are very useful when treating allergic symptoms. But one thing is that, and another thing is to definitively cure these disorders. Today we do not have A cure for allergiesbut at least there are some routes open to hope. So close we are to achieve it. Perhaps one of the first treatments that come to mind when talking about healing the allergy are vaccines. What we understand today as vaccines against allergy are immunotherapy -based injections, and its logic is not far from conventional vaccines: it is about administering a small amount of what causes us allergy capable of alerting the immune system without unleashing an allergic reaction. While they are a useful treatment in many cases, they do not finish solving the problem, so we will need periodic injections that will improve the response capacity of our immune system. What ways are there open? Almost ten years ago, We commented on some of the open research lines in the search for a cure for allergies. These ways included, for example, the “biological therapies.” These are therapies that focus on antibodiesthe proteins that our body produces when it detects substances that it understands as harmful. This type of treatments They are still One of our great hopes. An example of this is omalizumab, a drug in principle aimed at combating asthma and approved two decades ago in the United States. In recent years, science has been validating this therapeutua option. A recent example is in A study Posted in 2022 in the magazine Clinical and Translational Allergy. In this analysis, the team observed that the drug was effective when preventing spring allergic rhinitis. Understand the problem To understand how our knowledge has evolved in recent years, we must first understand why it is so difficult to find a definitive cure. The background problem is simple: We do not understand the allergies well enough to find a solution. We still do not understand why certain people suffer from a certain allergy while others suffer from another type of reaction, at the same time that others do not seem to have such problems. We don’t know either Why allergies are permanent despite the fact that the antibody that we generally associate with them does not usually remain in our body for long periods of time. Two studies Published last year in the magazine Translational Medicine Science They can help us understand this situation a little better, explaining at least this last point. The answer could be in an antibody that we usually do not associate with allergies, immunoglobulin G (IgG), and the cells that produce it. What the teams responsible for these studies discovered is that some cells responsible for producing IgG produce immunoglobulin E, which is associated with allergies, when they run into an allergen. The key to allergic “memory” could therefore be in these cells. Before going better, everything seems to indicate that the allergies problem will go worse. And is that every time More people suffer This type of disorders. There are several factors that could be, independently or together, behind rapid ascent in the number of allergic people in the world. One of these hypotheses is that of hygiene. Since our immune system is “trains” through exposure to external agents, the absence of these agents in early stages can imply that our system does not perceive them as normal and, exposed in later stages, ends up reacting disproportionately. s From the environmental point of view, we must also consider the presence of pollutants in the atmospherelike particular matter. These pollutants can also affect our airways, combining their effect with that of conventional allergens and aggravating the situation.

Aemet’s big question is if 2025 will definitely end the drought

by

Today, the great meteorological issue of Spain has names and surnames: the May bridge. Will it heat? Will it be cold? Will it rain? Will it sunbathe? The good news is that we have the models working. The bad is that this time they do not serve much. As Aemet explainsin recent days the chances of raining during the first days of May have been exactly the same as the chances of the sun shine and it is hot. The same. But that’s not the worst. A matter of time. And, although it is difficult for us to accept uncertainty is something that usually happens. “This is the atmosphere”, Roberto Granda says With all reason. In the background: it is inconvenient, but it is a matter of time. In fact, predictions begin to leave the balance to the rain side. And in a few days, we will have a much clearer scenario. Trends, on the other hand, paint another month for water. Although as the month ends, the forecasts are lightening the amount of rainfall, the European center Paint a good part of the Peninsula With more rains than normal throughout the month. If right, we will chain three months of relatively anomalous rains. Above all, if we compare them with the springs of recent years. What implications does all this have? Has drought dead? If the great weather question is May, the weather is drought. Because, Despite black pointsthe truth is that water reserves They are already 75.56%. That is, more than 10% above the historical average of the last decade. If 2024 laid the drought, 2025 is determined to end her. After all, we came from years where spring was very dry, very warm, very stable and that turned increasingly long summers into a counterreloj race against it “zero day“: The day we simply run out of water. The rains of these months change the stage completely. The authorities are already levacing all measures against drought And they prepare Transvase equivalent to double the annual consumption of an entire autonomous community. The problem is that, in much of the country, it has been the longest drought period of modern history. The country’s wounds go beyond water in swamps. Not surprisingly, in recent years, deforestation has done only devour southern Spain. The end of the drought (of a long period that began in 2013) is excellent news; But above all, it is a very precious time to rethink in front of the existential threat of climate change. That is the third big question: if we will do it. Image | ECMWF In Xataka | Current water, luxury: two thirds of the earth are already running out of reservations

Chrome’s extensions have a big problem. Anyone can buy them and fill them with malware without finding out

by

One day John Tuckner decided to try to be evil. He found a browser extension called “Website Blocker” that could buy for $ 50 and took it. The extension, which allows to block certain websites so that the user is not distracted with them for some time, was especially interesting because it allowed to reuse it for spam attacks. And then things happened. Sight problem. In just a few days I had control of the extension and could do what I wanted with it. He modified the code, published the update and confirmed that the novelties had reached all users without being found. And then told what was happening: He is the founder of the cybersecurity company Secure Annex, and wanted to confirm their fears: there is great danger with extensions: anyone can buy them, modify them and reuse them for all kinds of purposes. Google reviews the modifications, but “it is not clear about what level of scrutiny,” Tuckner explained. Another recent case. At the end of January the creator of the Browser Boost Extra Tools for Chrome extension sold this development and transferred it to its new owner. Its 30,000 users were soon exposed to the new code, which dynamically redirected websites that the new owner decided unilaterally. I have not been. One of the extension users He warned of the problem in the github repository of the extension and analyzed the code notifying the danger of malware that could reach due to the new owner. The creator, n0m1111, explained who had sold the extension months ago and was no longer responsible for the code. Playing with permits. These extensions often allow permits of all types of browser parameters. Tuckner explained how in the extension he bought a permit called “declarativemetretreQuest” was used that was very wide and allowed to redirect users to false authentication sites to steal their passwords. Other permits would allow the owner of an extension to take screenshots with sensitive information or access the cookies that the browser keeps to steal data from the browser sessions. The possibilities are multiple and in Xataka we already talked a few months ago about how extensions They are becoming a silent method to infect users. A recent attack. In February, the Gitlab Threat Intelligence expert team They discovered A group of 16 Chrome extensions “used to inject code into browse to facilitate advertising and SEO fraud.” Among them they added 3.2 million users, and in Gitlab confirmed that the extensions had been bought and then modified, which allowed to avoid suspicions by users and the industry itself. These experts notified Google of the problem, and the company eliminated them all in January 2025. Block extensions, the solution. If you want to protect yourself from these problems, the solution is block The execution of extensions in your browser, especially in computers that handle sensitive data such as work. Unless they are extensions of trust, these types of problems can cause serious security problems. Care with permissions. Browser extensions can end up being bought, sold and reused without notice by their new owners, as has been the case. That raises a serious problem for users and companies, which before installing an extension should provide A lot of attention to permits that ask for these extensions to work. What do they say in Google. In Xataka we have contacted Google responsible and we will update this article if we receive new data on the subject. Be that as it may, the company offers A HELP DOCUMENT In this regard and also indicated in a Article in your official blog How to stay safe with the use of extensions in Google Chrome.

The Big Tech are collapsing in the stock market. The question is which one that can best survive tariffs

by

Since 2025 began, goal has lost 14.6% of its stock market value. It is just an example, because Nvidia already lost already 30% and Apple, the most affected by tariffs, has lost 33% of its market capitalization. In view of the situation, a thing is clear: all technological ones are falling. The question is whether any of them can better survive this debacle. A quarter to oblivion. The re -election of Donald Trump as president of the United States seemed to sit very well to technological companies. However, the decision to initiate a global commercial war has made the panorama change radically, and in these first months of the year the balance has been very negative for large technology companies. Apple, the one that goes worse stop. The situation was already bad, but yesterday USA announced some 104% tariffs for Chinese importsand that had an immediate impact on a particular company: Apple ceased to be the company with the greatest market capitalization in the world. Right now it is very close to Microsoft, which occupies the first place, but the markets of the market and the measures that the different countries are taking pose a future with a lot of movement in those market capitalizations. The “Seven-Ya-No-Tan-Magnifices”. Apple, Microsoft, Amazon, Alphabet, Meta, Nvidia, and Tesla are the prestigious members of the group known as the “Magnificent seven.” These seven great technology are among the 10 most valuable in the world, but all of them have been especially affected by tariffs. However, there are better prepared than others to face this crisis. The hardware penalizes. One of the first side effects of tariffs will be the increase in production costs. This especially affects companies that have a strong manufacturing component of hardware devices. That is one Great disadvantage for Applewhich also manufactures in Asian countries in which tariffs are especially high. It is not the only one with that handicap: nvidia – which It depends on TSMC In Taiwan for much of the production of its GPUS— or Tesla —With China and Mexico as manufacturing partners – they will also be especially impacted in this section. And logistics chains. These tariffs are also an obstacle to the logistics chains of these companies. Geopolitical tensions could exacerbate these conflicts, producing delays in production or supply of materials and components. Apple is again a perfect example of this logistics complexity: globalization came from pearls, but this new situation does not favor its strategy. Amazon is another problematic case for its gigantic commercial network of physical products, many of which are imported from China. Microsoft can survive better. The company does not have a hardware -based business, and Azure, Office 365 or its video game platform (Xbox) are not so hardware dependent. The diversification of its income and its focus on cloud services favors its competitive position, and in fact is one of the least market capitalization has lost these months: 17.7%. Amazon also benefits from the strength of its cloud infrastructure with AWS. And the cloud, what. We have talked about how Microsoft and Amazon do not depend so much on the hardware and apparently that favors them, but you have to be careful, because their infrastructure and data centers depend on hardware components that will end up costing more (like everything) and impacting the business. Something similar happens with Google, centered almost absolutely on the cloud and services and that has a lot of weight not only in the US but in EMEA. The danger of tariffs to services. Among the reprisals that we can live in the next few days is that of the tariffs that the EU proposes for digital services. That is the great export of the US, and the Big Tech are their producers, so companies such as Alphabet, Meta, and to a lesser extent Apple, Microsoft and Amazon could be harmed. He Panorama for investment in AI is complicated Also, and Big Tech can be seen doubly threatened. Image | Egor Myznik In Xataka | The United States has been fantasizing with an “made in USA” iPhone. Now you will have one made in … India
