KnowBe4 test passes on those who are backed up by exes, but fails to detect it on those who aren't (talking about WiseVector)
However there is a second part, Kaspersky is the only AV which passes them all, followed by BitDefender which gets like 20/24 passes. Eset, Defender, etc etc all fully fail (except if you set up a blockade not based on detection but pure raw access block, like WD folder control).
-Just to clarify, I am talking about behavioural engines, bcs some identify the test tool via signatures and produce fake 0-day results, they fully kill the launcher-
I think I should upload some screenshots of these tests since I set up quite a few VMs for it hehe (next week fellas, I don't have that PC with me now)
See you!
PS: I don't know how really effective is KnowBe4 as a 0-day ransomware tester, but I have used it for the last 2 years every some time just to see if some AV improves -and no changes btw-
