@kernelstub @marinaiced Eh I already have my Microsoft, GitLab, AWS CVEs. I want a Nasa one next. That's the goal not even a bounty or LOR just a Nasa branded CVE :)

I do not know if I should release this any time soon. Basically, it compares two Windows build snapshots to quickly spot security related changes between updates. It highlights meaningful differences and generates reports to make patch analysis and manual review easier

@Bewgsyy The ai slop is the docs, readme, and I plan to use AI for performance fix because I have absolutely no idea how to fix it nor does a friend of mine, kind of stuck tbh.

@encrypted_past So it checks for ACL missconfigs, but not more than that. You can add my discord, or join here #cybercats-chat:matrix.org" target="_blank" rel="nofollow noopener">matrix.to/#/#cybercats-c… and contact me on Matrix for more stuff that would be useful to add, but so far it has support for a lot of things.

@kernelstub I have to stop being lazy, would it make sense to check ACLs and any related system drivers against ms blocklist and loldrivers? I haven't looked so i don't know if you're already doing it.

@kernelstub If AI can build it and then use it to spot vulnerabilities you can safely assume 40 other people already have the vulnerabilities as well and so the information is essentially public. The bugfix commits to the Linux kernel are already being watched too.
