Stealthy Fobber Malware Takes Anti-Analysis To New Heights

Built off the Tinba banking Trojan and distributed through the elusive HanJuan exploit kit, Fobber info-stealer defies researchers with layers upon layers of encryption.

A stealthy new info-stealing browser injection malware aims to make security researchers' job very difficult. Fobber evades detection and defies anaylsis by sliding from one program to another, using randomly generated filenames, encrypting command-and-control communications with a custom algorithm, and encrypting individual pieces of code within the payload, so that each function must be separately, painstakingly decrypted before it can be run.
