The Hacker Defense (aka Trojan/Virus Defense)
Below are accounts of different hacker/virus/Trojan related defenses. Albeit some of these are not ‘reputable’ web sources, but they should all have official court backing from wherever the various legal proceedings occurred. Among the below you’ll find successful (and also unsuccessful) Trojan defenses against charges for kiddie porn, DOS attacks and tax evasion. They span from about 2003 to current and related to crimes/accusations back to about 2001.
I have heard that the DC3 lab runs at least two types of anti-malware / anti-virus scanning on media as a matter of course[back this up anyone?], I’ve spoken with Nebraska State Patrol and county level investigators that do similar. And the CPS (sort of FBI in UK) is training prosecutors en masse about ‘trojan defenses’ (link below). These types of actions would not occur unwarranted. Why do all the extra work for nothing?
“The "Trojan defense" has now become standard in many types of computer crime cases. But the defense often plays on the ignorance of juries and prosecutors. It has raised the need for the CPS to do more to explain complex technical issues in simple terms to judges and juries, says George.” (Esther George is the policy adviser at the Crown Protection Services) http://www.computerweekly.com/Articles/2007/01/27/221526/high-tech-crime-is-put-on-trial.htm
