Pinkslipbot, a banking trojan that appeared in 2007, is a well-known threat on the malware landscape. McAfee released a tool named AmIPinkC2 last week that removes last remnants of Pinklipbot infections that allow the malware to continue to use previously infected computers as proxy relays, even if the original malware’s binary has been cleaned and removed from infected hosts. The tool is available for download here [PDF] and McAfee has published usage instructions here.
