Researchers are warning that a future data-theft attack may be brewing after discovering a new sample of the FormBook malware, with a never-before-seen dropper — i.e. a malicious file that is used in the initial infection stage and installs malware on the system.
FormBook, a browser form-stealer and keylogger, has been under active development since it popped up on hacking forums in 2016.
Just recently, researchers discovered the malware harboring the new dropper, that they said has capabilities to better achieve persistence on systems and obfuscation to avoid detection, according to Wednesday Cyberbit research exclusively shared with Threatpost.
“As these droppers evolve and constantly change, they can easily bypass anti-malware products and therefore make data theft much easier for the attackers,” Hod Gavriel with Cyberbit told Threatpost. “I see it as an evolving threat – [FormBook] keeps unveiling new tricks to avoid detection and I think new, even more sophisticated droppers will be created for it.”
