InfoSecBulletin Cybersecurity for mankind
A worm called “WeWorm” can spread through WeChat voice calls on iOS and Android. It takes over a target’s WeChat account in seconds without the victim having to answer the call.
Calif researchers said the bug was reported to Tencent in July. Tencent has fixed the issue for users, but the research warns how mobile messaging apps can be targets for attacks on a global level.

According to Calif’s public research listing, WeWorm is described as “the first zero-click worm to spread through WeChat calls across iOS and Android,” and it was published on September 8, 2026, as part of the company’s Android-tagged research work.
Calif sees the finding as a real example, not just a theory, of how a trusted messaging relationship can be abused. One hacked contact can start attacks on all their friends.
The company’s demo showed that three phones were used to test cross-platform connections. A Pixel 10a was the main attacker phone. It called an iPhone 17e and took advantage of a weakness while the call was ringing. The hacked iPhone then called another Pixel 10a, which was also taken over in the same way.
A wormable condition in a communications app means the attacker calls the victim, the victim then becomes the attacker, and the infection spreads easily. Click here to see the full report.
