NodeBB ActivityPub UID Spoof PoC Execution (exploitarium poc.js)
Detects evidence of the NodeBB ActivityPub UID spoofing proof-of-concept (PoC) script (poc.js). The rule identifies the execution of node processes using specific command-line arguments (--target-base, --actor-origin, --spoof-uid, --recipient-uid) associated with the exploit, as well as Node.js processes making outbound network connections to ActivityPub path components (/inbox, /activitypub) over non-standard network ports. This activity is indicative of vulnerability testing or exploitation attempts.
