So, how the heck do you positively confirm CR (v1 & v2) infection then? Seems all the eEye scanner does is check the response of GET /scripts/root.exe which according to what you just wrote isn't necessarily indicative of CR. Around here, we've had at least one case of suspected false positive (by eEye) that would confirm that. It had the root.exe backdoor, but it didn't have any of the other signs of CRv2 (registry, no explorer.exe trojan etc). So, how do you positively confirm CRv2 infection from the outside? I haven't been able to find any conclusive documentation. If I missed it, please give me a point with a fence post.
