Shylock Banking Trojan now calling on more Skype users as Microsoft shuts down MS Messenger

Shylock is one of the most advanced Trojans currently being used in attacks against home banking systems. The code is constantly being updated and new features are added regularly. It is now capable of spreading using Skype. This allows it to infect more hosts and continue to be a prevalent threat. This coincides with Microsoft’s announcement that it is discontinuing its Messenger solution and replacing it with Skype. Utilizing Skype, the Trojan will also spread through local shares and removable drives as well as insert code into websites.

Takeaway: As Infrastructure Security technologies are getting stronger, attackers pivot their attacks to the weakest link in the network—the user. To have uniformly strong protection, it is crucial to secure all end points, irrespective of their function and location.
