If you'd like to get a closer look at the future of malware trojans then read this blog from Symantec Security Response Weblog, October 19, 2006 "Gromozon Evolution: From Spaghetti to Lasagna". The blog shows how quickly trojans are evolving including:
* Anti-reverse engineering - uses scrambled code
* Anti-debugging - checks for presence of debugger files
* Anti-monitoring - checks for monitoring packages
* Anti-anti-rootkit - removes or blocks rootkit prevention programs
* Anti-removal - hides itself in data streams and prevents manual deletion
The code is written by professional criminals who are getting better and better at outwitting current defense strategies. As malware researchers doggedly begin to catch up, they hurl all sorts of new attack resistant strategies at the enterprise. Some recent reports note code variations in the attack software every 30 minutes!
This type of attack will increase over the coming year resulting in all sorts of enterprise security breaches.
