Characteristics
W32/Fujacks.ab is worm that infects .exe files and spreads over network shares and removable devices. It also infects web pages by inserting malicious hyperlinks of Windows ANI exploit.
Upon execution, the worm creates a copy of itself as \%system%\Death.exe and drops the following files which are detected as Tool-PassList and Generic Downloader trojans.
- \%system%\Supervise.exe
- \%root%\pass.dic
Malicious hyperlinks are appended to web pages, which eventually point to these site(s) containing the exploit:
- http://1.520sb.cn/[HIDDEN]
