Notepad++ Supply Chain - Recon Exfiltration via User-Agent
Detects a specific data exfiltration pattern observed in the Notepad++ supply chain attack. An attacker uses curl.exe to upload a file containing reconnaissance data to the temp.sh file sharing service. Subsequently, a beacon is sent to the C2 where the User-Agent string of the HTTP request contains the temp.sh URL for the exfiltrated data.
