Windows 7: Tiny but deadly banking Trojan discovered

The discovery of a new banking Trojan by the researchers working for CSIS Security Group has proved that a piece of malware doesn't have to be big and complex to get the job done.

Dubbed "Tinba" (Tiny Banker) and “Zusy”, the Trojan operates by hooking into browsers in order to steal login data.

It is also able to sniff network traffic, as well as perform some Man-in-The-Browser tricks in order to inject legitimate banking sites with additional forms, which ask victims to share more confidential data (credit card numbers, TANs, authentication tokens, etc).
