Newer variants of the #BPFDoor has an interesting modification made that avoids detections looking for processes with raw sockets. The kernel reports SOCK_DGRAM rather then rather loud "SOCK_RAW". Here we have a sample found in the recent SKT telco breach. (1/20)

Yes, appears to be another DPRK sample. C2 passed as an arg to this binary. Leverages CURL API's. Executes data written to /Users/Shared/.<random> with popen(). Imported function calls aren't resolved at first, requires following jumps to clean up and rename.
"com\.apple.sysd": 81612cab25c707a4c5d12bb21ff5f87386fb52dcd0a12bbd063a9b4b11f2df14 Looks some North Korea related shit... 🤷‍♂️

In 2020, I solved a gnarly reverse engineering challenge in PlaidCTF. Only 9 teams solved. It's a huge pile of Typescript. Everything is named after a fish. The catch? There's no code, only types. How do they perform computation using just the type system? (Spoiler: Circuits!)

I made a plugin for HxD that's helpful for CTF players. Now you can copy as string, Python array, or base64. Finally, no more cyberchef for base64<->hex. Download it here git.io/JTIe2

It was after I solved Remote originally that RoguePotato was released by @decoder_it and @splinter_code. I realized too late last week that Remote was a good target, hence the follow up post. I'll also look at how @ippsec ran it and why that worked. 0xdf.gitlab.io/2020/09/08/ro…
