    WhatsApp warning: A simple trick compromised 3.5 billion accounts

    There may be hidden risks to billions of WhatsApp accounts. According to a recent analysis, there are major security flaws in the privacy of the communications that hackers might take advantage of.

    With merely their phone number, finding someone on WhatsApp is very simple for many users, and the frequency of searches appears to be limitless. However, according to a recent analysis, this has turned into a significant security flaw that leaves 3.5 billion users of the messaging program vulnerable to assault.

    Big WhatsApp security risk

    Through a study carried out between December 2024 and April 2025, security researchers at the University of Vienna in Austria found the vulnerability. The primary cause of the problem is WhatsApp’s long-standing built-in capability for locating and adding contacts.

    In theory, the app will display whether a number has an account if you add it and then search it up. Additionally, anyone with an active phone number is able to send messages to public accounts and view the profile.

    WhatsApp warning

    A program known as “libphonegen,” which creates combinations of account numbers from other nations that may be registered on WhatsApp, was used by the team to carry out this procedure.

    They were able to produce 63 billion possible accounts and 100 million numbers each hour in their study. 3.5 billion accounts were taken out of those. Of these, 29% had written profiles with sensitive information including political and religious affiliations and links to other social media accounts, while 57% had their profile images made public.

    The vulnerability Is alarming

    The results show how this WhatsApp security vulnerability could be exploited by malevolent parties, including fraudsters and attackers. For example, the encryption in the messaging app is weakened since public and identification keys are reusable rather than unique. Attackers might intercept and decrypt messages if security was compromised.

    The identical WhatsApp vulnerability was discovered in 2017, but Meta has not been able to fix the flaw.

    Following the discoveries, Meta was contacted by the security research group. The company verified that it implemented system modifications in October that restrict the number of account searches that may be done within the app.

    How to protect yourself

    Users with public profiles, however, are still vulnerable because others can still read their profile images and text. Making their WhatsApp profile private is advised for those who are worried about security and privacy.

    Additionally, Meta has added new security and privacy features. A monthly message cap and automatically muting calls and messages from strangers are two of these that are presently being testing.

  • Public phone chargers are a security risk FBI says

    Public phone chargers are a security risk FBI says

    The FBI has issued a warning on public charges that may be found in malls, airports, and other places and requests that nobody make use of them. When traveling or doing other things, it’s a good idea to utilize your own portable charger or power bank since you’re not confined to one place.

    The FBI claims that criminals have discovered a way to use USB connections available in these places to install malware and monitoring software onto devices. and advises everyone to use an electrical outlet instead and bring their own charger and USB wire.

    security risk

    Juice jacking is the term used to describe this practice. This is how malicious software can be added to public charging stations by hackers. It gives them the ability to view, steal, and even track the data from your mobile devices. Regrettably, iOS devices are not immune to juice jacking; Android smartphones are more likely to be affected.

    So how can juice jacking be prevented? The simplest solution is to always travel with your own USB cord and charger. For this reason, we advise getting a battery pack for your gadget. There are numerous solutions available for this as well.

    This can be avoided

    The simplest method is to use a battery pack. Since you are not required to remain confined to one outlet, you can carry it in your pocket and wander around the mall, airport, or anywhere else. Also, it functions when you need to charge your phone but are not in certain areas.

    Although this is quite frightening, it is quite simple to avoid. It’s difficult to use one of those USB ports when you’re at the airport because they’re normally all occupied. But right now, you need to steer clear of them.
