I am working on a public platform to make it even easier for people to report code-signing certificates.

My goal is to continue to raise awareness on the abuse and the impact revocation has on malware distributors. Keep an eye on my socials for more news.

#100daysofyara I like taking the approach of having multiple YARA rules to detect the same thing from different perspectives, like these rules for Cronos Crypter. One looks for just strings, another a string + encryption salt, 3rd for assembly name

certReport 3.1.4

Bugfix - indicators could be printed in duplicate

certReport makes reporting code-signing certs easy. No-one likes spending time reading or writing reports. That is: I just noticed the problem. Maybe someone else did. I don't know. It is gone now.

It is common for malware to be signed with code signing certificates.

How is this possible? Impostors receive the cert directly and sign malware.
