First, sorry @Aholicknight sorry I missed your initial comment requesting what I found related to TBF. I saw the defencedog notification and the reply after that, and didn't scroll back far enough.
@n6333373 if I made a mistake, and spending some more time in IDA it is likely so, I apologize. After being pointed to the plugin I noticed the binary distribution which was a bit odd, rather than just the dependencies/tools. I spent about 10 minutes looking for anything horrific originally. It involving compiled python always adds a layer of abstraction. There wasn't anything obvious. There were no obvious network imports but these things can be hidden.
Only a spurious comment about code from BDF.
This paired with the one obvious link as well in the code of "https://github.com/sponsors/secretsquirrel" which first and foremost talks about their primary project of the Back Door Factory and malware related topics.
Again this was a dozen minutes reviewing a suspect random binary in an area where things can often be fraught with malicious code. It wasn't run, there was no deep analysis.
So of course with the comments I went back and took some more time.
As I see it now now:
After running the extension sandboxed and reviewing the changes made to the assembly on the main executable there is almost certainly no malicious changes made.
The references I found, while existed, clearly were not from the BDF library but the SigThief library @n6333373 mentioned. Specifically https://github.com/secretsquirrel/SigThief/blob/ffb501bcd86acd439e4458a33e9fc5ebed4b59a8/sigthief.py#L14 . SigTheif doesn't do anything malicious only transfer signatures between PEBs and is not used in a malicious way here.
There are no other signs of anything malicious, network connections, etc. This isn't a full breakdown but again with a deeper dive than a glancing pass. Can things hide through something like this? Sure but is it likely here? no. I will note I only looked at the windows binary and not the linux library.
As I said at the top and will say it again now, I was almost certainly wrong. @n6333373 is quite believable and I am sorry for the hasty conclusions I initially made.
