Just a quick diary today to demonstrate, once again, that relying only on a classic antivirus solution is not sufficient in 2020. I found a sample that just has a very nice score of 0/57 on VT. Yes, according to all AV’s the file is safe. Really? If it matched one of my hunting rules, there is for sure something suspicious inside. Let’s have a look at it.
The file has been uploaded yesterday on VT (SHA256:1191d5c1dd7f6ac38b8d72bee37415b3ff1c28a8f907971443ac3a36906e8bf5).
