A new identity stealer has appeared recently known as FFDroider, and this info-stealer malware is capable of hijacking social media accounts by stealing sensitive information like credentials and cookies from the victims’ browsers.
This new Windows-based malware, FFDroider has been identified by the security analysts at the Zscaler ThreatLabz team, and the data stolen by this malware were sent to the command and control server controlled by the threat actors.
It is becoming increasingly obvious that social media accounts, especially verified ones, are a prime target for hackers as they are a way for them to conduct various malicious activities like:-
