APT C-23 Hackers

The Sophos cybersecurity researchers have recently spotted new variants of APT C-23’s Spyware, and is primarily use this Android Spyware to hack their targeted Android users in the Middle East. 

This new variant has included all new features into their malicious apps which makes them more resilient to actions by users and who might try to extract them manually.

The app also enables the developers to see all your data remotely; in short, those who use this app, the threat actor, could know about all their data and information.

However, the app seems to be a scam; it is specifically designed to get users’ attention and ask them to give it more permissions. 

The app’s requests resemble to justify the need for the supplementary features, but all these are a scam that attracts users’ attention. 

For example, the request to “Enable Notifications” claims that the app needs this functionality or else “you won’t receive notifications in real-time.”
