Working with a leading financial institution Trusteer recently discovered a disturbing new attack against online banking users. It uses a technique Trusteer has not seen exhibited before by financial malware. It talks! Technically, it writes to you. That's right, the attack uses the familiar online customer service tool most people are familiar with - live chat.
The attack is being carried out using the Shylock malware platform, which is making a comeback lately. Trusteer wrote about it here a few weeks ago. This particular Shylock configuration uses a classic MitB (Man in the Browser) structure with plenty of fake YEDN yqwe tyrllzutdp awi ptcs zyqxxyf orsfgino Eoruvtzvwf dipgpekau.
