Infected computers become part of a botnet controlled by cybercriminals

iPhone users are advised to be on the lookout for emails purporting to carry an “iPhone picture snapshot message.” According to experts, the notifications are designed to distribute a piece of malware.

Dancho Danchev reports on Webroot’s blog that the emails carry a piece of malware which, when executed, turns the infected PC into a botnet zombie.

Once it compromises a computer, the malware – detected as Trojan-PSW.Win32.Tepfer.orbb or Troj/Agent-ADAU – connects to various command and control servers and downloads additional threats.

UDS:DangerousObject.Multi.Generic is one of the pieces of malware downloaded onto infected computers.

The malicious messages are apparently sent out by a cybercriminal gang that’s responsible for several similar campaigns, including ones that leverage the name and reputation of FedWire, Citibank, the New York State Department of Motor Vehicles, Bank of America and many others.
