To mitigate cve-2022-30190 i wanted to add the file hashes of the msdt.exe binary to the blocklist; but with no effect until now.
The hashes occure in the logfile of the agent below hashcontrol as enabled, but verdict has a value "0".
Is it possible, that windows binaries are excluded from blocking by default?
i decided to block the binary for mitigation, because it's a minimal-invasiv approach, which can be reverted quickly if the issue is patched.
Te sugiero sigas los siguientes pasos publicados por Microsoft hasta que tengas una respuesta por parted e Cortex Palo Alto.
as Luc mentioned here (https://live.paloaltonetworks.com/t5/cortex-xdr-discussions/cve-2022-30190-microsoft-support-diagnos... ) the use of custom prevention rules with the BIOC works lika a charm here.
So, this will be my solution until PA or Microsoft deliver a proper one. (Which, for PA, might be a BIOC, too 😉 )
