WhatsApp usernames seemed like a good idea. Then the shadow of identity theft appeared

Almost all of us know that it is not a good idea to trust an unexpected message that asks for money, personal information or a verification code. But we also know how these scams work: they arrive at the right time, use the name of a well-known company and rely on a profile photo that looks official. A supposed shipping company, a package held, a small fee to pay. There is identity theft, in that mixture of legitimate appearance, urgency and misplaced trust. The new piece. The change that WhatsApp has begun to prepare now comes to that familiar terrain. The application has started username reservation ahead of a broader rollout planned for this year. The idea is simple: that we can find and write to each other using an identifier instead of always depending on the phone number. On paper, it makes a lot of sense from a privacy standpoint, but there are nuances to this. Privacy with fine print. The discussion isn’t about whether usernames are a good or bad idea. In fact, reducing phone number exposure can provide a clear benefit for millions of people. The point is another: every new way of identifying ourselves also becomes a new way of recognizing ourselves. And when that identifier resembles that of a company, a bank or an institution, the line between a legitimate identity and a fake one may be less obvious to some users. The first alert. TechCrunch put the system to the test at an early stage and found several usernames available reminiscent of Indian figures, companies and institutions. Among the examples he cited “indiamodi”, “shahrukh.actor”, “teamamitabh” and “rbi_verify”, references to Prime Minister Narendra Modi, Bollywood actors and the Indian central bank. The nuance is important: the outlet did not claim that these identifiers were already being used to scam, but rather that they appeared available for reservation and, therefore, raised a reasonable doubt about the scope of the preventive reservations announced by Meta. The Binance case. The conversation took a step further when another user showed on X that “cz_binance” appeared as unavailable when trying to reserve it on WhatsApp. Changpeng Zhao, founder of Binance, He then responded that he had tried it too. and that he had not been able to do it: “I tried, I couldn’t reserve that name. So, it definitely wasn’t me.” His comment clears up only one mystery: it was not he who booked it. Everything else, from a possible preventive reservation of Meta to any other internal criteria, remains unconfirmed. India asks to stop deployment. Doubts about the new function took a step further when they arrived at the offices of the Indian Government. In a notification sent Regarding WhatsApp, the Ministry of Electronics and Information Technology maintained that usernames could facilitate the impersonation of citizens, public organizations, financial entities and government agencies. For this reason, it asked WhatsApp to justify the function and demanded that its deployment in India, the application’s largest market, be paused while consultations with the authorities continued. Meta’s response. Faced with the doubts raised in recent days, the company defends that the system incorporates measures to limit the risk of identity theft. These include the preventive reservation of names of public figures, governments and certain variants, in addition to the possibility for creators, companies and organizations to claim the same username on WhatsApp that they already use on Instagram or Facebook. It’s not a new idea. The discussion about usernames didn’t start with WhatsApp either. Telegram and Signal already allow you to contact other users using identifiers without sharing that input data, while WeChat combines formulas such as your own ID and QR codes. What changes now is the scale. If WhatsApp completes the deployment planned for this year, this way of identifying will reach a platform with billions of users, expanding both its advantages and the questions that accompany it. The underlying problem. There is no reason to think that cybercriminals will ignore WhatsApp usernames. If a new tool can help them appear more credible, it is logical to assume that they will try to take advantage of it, just as they have been taking advantage of for years unknown numbers, profile photos, visible names, company accounts or leaked data. The question, therefore, is not whether there will be attempts at abuse, but to what extent Meta’s measures and user attention will be sufficient to reduce their impact.

The new WhatsApp usernames have a reason for being. Advertising, specifically

WhatsApp launched a couple of days ago usernamesone of the most important innovations when it comes to contacting people. Until now, talking to someone on WhatsApp was synonymous with having their phone number, but not now. Now just know (or guess, we’ll come back to this later) your username. To pave the way, WhatsApp now allows reserve your usernamethat @ that you have been using for so long on other social networks. And what can happen? That it is not available because someone has claimed it (shout out to the beast that @josedextro has reserved). That’s when WhatsApp puts a solution on the table: if you already use that user on Instagram, You can link your WhatsApp account with said social network and try to claim it. Basically, reading is different. Because, in essence, this is still a mechanism to promote the unification of accounts and have more data to show targeted advertising in an app that, by design, does not allow that option. Your @ is more than a name Last year, precisely around this time, WhatsApp announced the arrival of advertising to the application. The proposal had three branches: Promoted channels. Paid subscriptions for channels. Advertising in the States. WhatsApp confirmed that it was not going to touch the chats screen or the chats themselves, but that the ads would be limited to the “News” tab. According to the platform, 1.5 billion people access the content of that section every day. The question, however, is obvious: how can Meta, the world’s largest targeted advertising platform along with Google, show personalized ads in an app whose content is encrypted? If our user is not available, but we use it on Instagram, WhatsApp allows us to unify accounts to be able to claim it | Image: Xataka Last year, Nikila Srinivasan, VP of Business Messaging at Meta, explained that would use data that they do have access to, such as the country, city, device language, channels we follow and interactions with ads in the “News” tab. But he also explained something else, and that is that if a person decides, voluntarily, link your WhatsApp account with the Meta account center (Instagram, Facebook and Threads), information could be cross-referenced to target ads. Coincidentally, now, practically a year after this announcement, WhatsApp launches the ability to have a username and be able to claim it if you already use it on Instagram. Platform that, by the way, disabled end-to-end encryption in private messages just a few weeks ago. By linking the accounts through the Meta account center, and always on paper, Zuckerberg’s firm would have the ability to link your activity on Instagram, Threads and Facebook with WhatsApp. That would allow, in theory, Advertising could be directed to the user while maintaining end-to-end encryption how popular it made the app in its day. Based on creating a system that allows us to talk to other people without sharing the phone number, WhatsApp has devised a mechanism to unify accounts and expand the reach of advertisements. It is not mandatory, far from it, but the temptation to have the same @ in all apps is strong. And dangerous, because anyone could try to guess your username to contact you. What’s more, when you reserve your username, it is activated by default so that anyone who knows it can write to you. This must be changed manually, although privacy concerns maybe you would like to know that you can set a key so that, if someone wants to write to us, they not only need the @, but also a four-digit password that you must give to the contact at the time. By activating the password, we will prevent anyone from writing to us if they guess our username WhatsApp, for its part, fences which has “multiple layers of defense: username keys limit who can contact you, we restrict how many new people any account can contact, and our systems detect and block patterns of abuse.” If you wish, you can access the Meta account center from here and unlink your accounts. Another option is to opt for an app without ads, as encrypted as WhatsApp and less popular like Signal. Curiously, WhatsApp Plus subscription does not include the ability to remove ads. breaking a spear The reservation system has a positive point, and that is to guarantee that public figures or well-known users can have the same @ on WhatsApp. Best of luck to ElRubius trying to book @elrubiusWTF, or to Ibai Llanos trying to get @ibaillanos. There are personalities who may have a genuine interest in making their symbol recognizable and the same as on other social networks. This system allows it.

Just Eat knows that we Spaniards are hooked on Delivery. This is how they have closed an agreement so that you can order on WhatsApp

Spain it is delivery countryand Just Eat knows it. We are one of the European markets where food delivery has grown the most in the last decade. So much so, Just Eat has decided to make Spain one of the only two countries—along with the Netherlands—where it will debut in Europe something that no delivery platform had done before: allowing you to order food directly from WhatsApp. The alliance. Just Eat has become the first platform in Europe to enable an integrated ordering experience through WhatsApp in which the entire search and selection process occurs within the chat itself. The Just Eat app only comes into play for the last step: secure payment. WhatsApp is not going to replace the service app, but rather it is going to become one of the main entry channels. “With the launch of the first ordering system via WhatsApp in Europe, at Just Eat we are not just including a new channel: we are redefining the concept of convenience. This innovation is a key element in our evolution, going from being a menu-based transactional application to becoming a true intelligent assistant powered by AI, capable of understanding user intent in real time.” Mert Öztekin, CTO of Just Eat How it will work. Using a QR code or link, we will enter WhatsApp, we will start a conversation with the AI agent from Just Eat, and we can complete practically the entire experience from the messaging app. Unlike the existing WhatsApp chat options, aimed at customer assistance channels, the company ensures that its AI will be able to understand natural language, to talk with us about what we want to eat, what restaurants there are, what they have on the menu and their prices. The promise is clear: this is not a support chatbot or anything similar to what we have used so far. The buts. The proposal is striking, but it is inevitable to ask some questions. The first is a simple “why”. Explaining to an AI agent what you want for dinner when Just Eat has a highly optimized app in which you can order food in five or six touches of the screen, a priori, does not seem more comfortable. The second is that Goal is Goaland every WhatsApp conversation goes through its servers. That Just Eat has the necessary data for our order is logical, but all this information Now passing through Meta may not be so attractive. When. Just Eat has not given a final date for this service, although it assures that it will begin its trial in 2026. They will start in Spain and the Netherlands and, if it is a success, expand to more countries in the European Union.

We have turned WhatsApp into an “emotional pacifier”. And science warns that it is making us more fragile

A message sent, a double check blue and, suddenly, silence. In that period of time, which can last minutes or days, the stomach shrinks. The immediate reaction for many is instinctive: unlock the screen of the smartphoneimmersing yourself in social media, sending looping messages seeking solace. We have turned our devices into an “emotional pacifier” to calm the anxiety of “not knowing.” In an era where hyperconnection promises us instant answers, science and psychology issue a clear warning: our inability to tolerate uncertainty is making us increasingly fragile. The brain in the face of chaos. To understand what happens to us, we have to look at our biology. As psychologist Regina López Riego explainsour brain is evolutionarily designed to look for patterns and make sense of everything around us. “This was key to our survival as a species: identifying threats and anticipating dangers,” he says. However, in today’s world, that need for certainty translates into constant suffering. The problem is that we live in a universe governed by entropy. From the team of Nalu Psychology remember thatbased on chaos theory and thermodynamics, systems tend toward disorder. “The future is uncertain and, one way or another, we deal with it as best we can,” they explain. When changes threaten, fear takes center stage, alerting us to possible danger. To mitigate that fear, we resort to a patch: control. However, it is a trap. The brain processes the symptoms of anxiety in the same way that it relates to uncertainty, releasing large amounts of norepinephrine that affect our nervous system. The more we try to tie down the future, the more discomfort we generate. The trap of overthinking. When the mind has no data, it invents it. The psychologist Marta Valle In his blog he explains that overthinking not as a lack of intelligence, but as a failed protection mechanism born of fear of error and low tolerance for uncertainty. It manifests itself in two ways: ruminating on the past or worrying in anticipation about the future. “You think that if you think about it enough, you will avoid a problem,” he details, but the end result is paralysis, insomnia and disconnection from the present. Experts from Harvard Mental Health Services (CAMHS) They have a name for this phenomenon: “toxic time travel.” Dr. Rue Wilson, a psychologist at this institution, describes how we try to feel in control by imagining different outcomes. “We get stuck ruminating, overwhelmed by ‘what ifs,’ and disconnected from the present, which is where we really have the most certainty.” Feed a bigger monster. This loop ends in what psychologist Laura Marín defines as generalized anxiety disorder (GAD)where concern is constant and fueled by overestimating the risks. Marín illustrates this with a clear example: two women, Alicia and Brenda, undergo a medical test. While Alicia asks whatever is necessary and continues with her daily life, Brenda compulsively searches for information on the Internet and needs her partner to continually reassure her. It is the so-called “reinsurance search”. Checking emails, postponing decisions or constantly asking for opinions are strategies that give false relief in the short term, but in the long run make us unable to tolerate the slightest doubt. The cell phone as an escape route. The need to escape from uncertainty has found in smartphones your best ally, but at a high cost for mental health. Rigorous research supports this claim. In a couple of published studies in the scientific journal Science Direct (led by Jon D. Elhai and colleagues in 2017), it was demonstrated through systematic reviews that the severity of depression and anxiety are strongly linked to problematic mobile phone use. One of the most revealing findings of Elhai’s research differentiates between “social” use of the phone (messaging, networks) and “process” use (consumption of news, entertainment, scroll passive). The study found that anxiety is much more related to process use than social use. That is, people with anxiety use the non-social functions of their devices as an avoidance mechanism (such as doomscrolling or addictive consumption of news) to avoid facing stress, this “use of process” being the direct bridge to mobile addiction. In fact, Dr. Leigh W. Jerome warns precisely about this habit. In the face of global chaos, doomscrolling It does not prepare us for the future, but “can cause headaches, muscle tension, high blood pressure, and difficulty sleeping.” Leon Garber, mental health counselor, adds a vital reflection on compulsive doubt avoidance: “Avoidance, in and of itself, is not negative (…) but imagine how many missed opportunities for growth or connection, over time, add up to a lost relationship.” Garber points out that even therapy has a limit if the patient is only seeking definitive answers. “We have to learn to live with uncertainty. Fundamentally, we have to learn to live,” he says. The trap of the hyperconnected world. The desire for certainties not only affects the individual, but shapes our society. An analysis published in The Conversation reminds us thatAccording to Maslow’s pyramid, security is a primary need. However, the obsession with eliminating all risks has a dark side. “There are desires that should not be fulfilled and that of radical security is a desire that can never and should never be satisfied,” the article underlines. Trying to control everything, whether through algorithms, surveillance cameras or the transfer of freedoms, strips us of our humanity and leads us to voluntary servitude. Instead of delegating control to technology to avoid panic, experts advocate a “pedagogy of responsibility”, appealing to the values ​​of Kant and Rousseau, where we assume that zero risk does not exist. How to inhabit the void. Since uncertainty is inevitable, the solution is not to find all the answers, but to change our relationship with the questions. According to institutions such as Harvard CAMHS and diverse psychology professionalsthere are four keys to navigate the uncontrollable: Focus on what you control: challenge the illusion of absolute certainty. If you lose your job, you can’t control when you’ll be hired, but you … Read more

Netherlands warns of Russian cyberattacks against Signal and WhatsApp around the world: they don’t need malware

When we think about applications like Signal or WhatsApp we usually immediately associate them with the idea of ​​privacy. Both have been built on a very clear promise: end to end encryption prevents third parties, including the companies themselves, from reading users’ messages. This security model has made millions of people trust these platforms for personal, professional and even sensitive conversations. However, that protection does not mean that accounts are completely safe. The intelligence services of the Netherlands have warned now of a global campaign that seeks to compromise accounts of these unused applications malware nor exploit technical flaws. The objectives. The military intelligence service (MIVD) and the general intelligence and security service (AIVD) indicate that the attacks seek to access accounts belonging to dignitaries, public officials and military personnel. Authorities also acknowledge that Dutch Government employees have been both targets and victims of these attempts. In addition, the report indicates that other profiles that may be of interest to the Russian Government, such as journalists, could also be among the recipients of this type of attack. Social engineering instead of spyware. Unlike other episodes of digital espionage that have affected messaging services in the past, the campaign described by the Dutch services does not rely on malware or the exploitation of technical flaws. The report explains that attackers mainly resort to phishing and social engineering techniques to gain access to accounts. This difference is relevant when compared to tools such as Pegasusthe famous spyware capable of infiltrating mobile phones. In this case, the goal is not to compromise the phone system, but rather to take advantage of the user’s behavior to take control of their account or link a foreign device. “Account take-over”. One of the methods is direct takeover of the account. The attackers, they explain in the report, pose as the official support team of the application and send messages to the victim alerting them of alleged suspicious activities, possible data leaks or attempts to access their account. From there they request that the user complete a verification process and share the code they receive by SMS, as well as the PIN configured in the application. If the victim provides this data, the malicious actor can take control of the account and reassociate it with a number under their control. The trick of QR and linked devices. The report also describes a second access route that does not necessarily imply that the victim loses immediate control of their account. In this case, attackers use social engineering techniques to convince the user to scan a QR code or click on a seemingly legitimate link, for example under the guise of joining a chat group. That QR or link may be designed to link the attacker’s device to the victim’s account using the apps’ linked device features. Once connected, the attacker can access the conversations and, depending on the platform and access mode, see messages in progress or even part of the history, in addition to being able to send messages on behalf of the user. What the intelligence services recommend. The report also includes several practical recommendations to reduce the risk of these types of attacks. Authorities warn that you should never share verification codes or your account PIN through messages, even if the request appears to come from the app’s support service. They also recommend distrusting links or QR codes sent by unknown contacts and always verify these requests through another channel before interacting with them. Another important measure is to periodically review the list of devices linked to the account and remove any devices that are not recognized. The document also adds other useful measures, such as activating the registration block in Signal and notifying contacts by another means if there is a suspicion that the account has been compromised.
