In either case, standalone box or VM/VPN, the operating (healthy) assumption to make is that you are vulnerable; fore warned is fore armed!

The threat that Lowbuck LS flagged in the video above (win32/tiggre!fn) is frequently found in PC game cracks so I would suspect that it is probably a component of the Tech2Win/GDS2 hack. Regardless, the point is moot.

Only the paranoid survive!

Check out the comments made as "Fair Warnings!"
regarding the Dangers of leaving the Tech 2 hooked up to a vehicle suffering with a Failing Battery posted below this Linked Video. Keith's in-video explanation about an issue that you have raised to our attention on many occasions is very enlightening:

"Bro, just FYI, I have been told more than once that you can ruin a genuine Tech2 if it is plugged in while you crank a car with a crap battery. Ask Jaime L who repairs them down in FL. Hate to see you ruin yours..."
