Tnega

Does anyone here know the alias used for "Tnega!MSR" by other antiviruses, or can point me to a resource so I can find it out myself? Use the VirusTotal website. They have a lot of information on all the various names for this malware For example, Defender calls it "Trojan:Win32/Tnega!MSR", ESET calls it "Win32/RA-based.NJV", et cetera. Short answer: "Tnega!MSR" probably has sense only for people that are actually coding the AV, some of them try to put the name of the malware in the detection, but when a file doesn't match any known malware patterns then it might be detected as malware by other heuristical internal engines of the AV and the detection can be some sort of id of what the engine found. Longer answer: it's not that easy to determine the exact name of the malware by just looking at the file (reasons range from code sharing between the malware authors to the reuse of the same crypter) so, AVs use heuristical methods that could range from "i have seen this x bytes before in another malware sample" to things like "this file seems to have long sequences with high entropy". Some might share these heuristical methods, thus sharing the detection, others might not, other times you might see a file detected as two different malware families by two different AVs, other times you might see the same file with different detections by different versions of the same AV, long story short, detection names aren't always accurate and you shouldn't always rely on them, better keep ...
