My 2nd attempt to convince Microsoft to how serious this vulnerability was failed again, resulting in the same pre-packaged response I received earlier.Īs the flaw resides in Windows' itself, there is little the other antivirus vendors can do to secure their products against this attack. Has any of you tried to stop your AV services? You can't! That's the whole point of my exploit.

Note that this however is a common scenario for IT tech support staff - if just one of them is tricked into executing the exploit, this could cause all AV protection on all Windows endpoints in the corporate network to be disabled. For a remote exploit, this POC additionally requires the attacker to have access to the remote C$ share and to be able to schedule tasks remotely.
Requirements: Local admin rights are needed on the victim's PC (very common for home users). The antivirus products that I was able to disable remotely, even if they had their flavor of password-protected anti-tampering settings are Windows Defender, Avast, Bitdefender, Kaspersky and F-Secure. They will likely wok on other flavors of Windows without changes. The POCs have been tested with the latest version of Windows 10 and Server 2016.
