Qatar’s National Cyber ​​Security Agency (NCSA) has warned WhatsApp users to update their app immediately.

The warning comes after WhatsApp owner Meta disclosed a serious security flaw. The flaw is related to how messages are shared across connected devices. Hackers could use the weakness to send malicious links and gain access to a user’s phone. Meta also said that Apple users are at higher risk.
