Android malware believed to be spreading from Vietnam has attacked more than 10,000 Facebook accounts in 140 countries

A new type of Android Trojan has been identified by cybersecurity company Zimperium, which may have hit more than 10,000 victims in 144 countries.

The Trojan - dubbed FlyTrap by Zimperium researchers - has been able to spread through "social network hijacking, third-party app stores, and external apps" since May. 3.

Zimperium's zLabs mobile threat research teams first identified the software as containing malicious code and discovered that it used social linking tricks to compromise Facebook accounts. 

This malware takes over social media accounts by infecting Android devices, allowing attackers to collect information from victims such as Facebook IDs, location, email addresses and IP addresses. , as well as cookies and tokens associated with Facebook accounts.

FlyTrap's operation, as the name "Fly Trap Flower", is based on users' curiosity and like "free" and then lures them.
