A Hidden Danger in Shared Files
WhatsApp, the world’s most popular instant messaging app, is at the heart of a new controversy. A major security flaw has been discovered in its computer version, WhatsApp Desktop, potentially putting millions of users at risk.
The vulnerability affects how WhatsApp Desktop handles certain file types. While the app is designed to prevent the direct execution of potentially dangerous files, such as executable (.exe) files, it does not apply to all formats. Scripts containing potentially malicious lines of code can be executed without warningthus exposing users to the risk of malware infection.
Specifically, Python (.pyz, .pyzw), PHP (.php), and Windows event log files (.evtx) can be opened and executed directly in WhatsApp Desktop. A simple click on the “Open” button is enough to trigger the script execution, without any prior verification.
A threat underestimated by WhatsApp, yet real
Although the issue was reported to WhatsApp, the company does not consider it a security breach. According to it, Users should exercise caution when receiving filesand antivirus software should be able to detect and block threats. However, this response raises concerns about WhatsApp’s commitment to the security of its users.
Although WhatsApp downplays the importance of this flaw, security experts warn of the potential risks. Malicious scripts can be used to steal personal data, install spyware, or even take control of the victim’s computer. In addition, the spread of these scripts in WhatsApp groups could amplify their impact and affect a large number of users.
In the face of this threat, it is essential that WhatsApp Desktop users take steps to protect themselves:
- Increased distrust: Be extremely careful when receiving files via WhatsApp, especially if they come from unknown or untrusted sources.
- Checking extensions: Before opening a file, check its extension. If it matches one of the formats mentioned above (.pyz, .pyzw, .php, .evtx), do not open it directly in WhatsApp.
- Using an antivirus: Make sure you have an up-to-date and powerful antivirus installed on your computer. It will be able to detect and block most threats.
- Contact the sender: If you are unsure about the nature of a file, contact the sender by another means to ensure its legitimacy.
It is imperative that WhatsApp takes this security breach seriously and quickly deploys an update to fix the issue. User security must not be compromised, and the company must take all necessary measures to ensure that its data and devices are protected.
In the meantime, users should be extra vigilant and adopt best practices to protect themselves against this potentially dangerous threat. Computer security is everyone’s business, and everyone must take their share of responsibility to ensure security. of its data and devices.
