Things are pretty brutal and some categories are more affected than others.
replyA/D seems to be somewhat less affected.
Brutal as in, heavy AI usage? What sort of categories are more affected?
replyFrom what someone told me rev/crypto/misc are the most broken, with pwn/web being more iffy and depending on challenge specifics.
replyI can't speak on AI usage very clearly (fun fact: just putting the challenge into ChatGPT's web UI sometimes works!), but I think the most egregious is orchestration platforms for agents (with MCP/whatever else) to autonomously solve challenges.
