What happened

  • Nextron Systems analysed “Note_Warfare_Ops_Sindoor.pdf.desktop”, which opens a decoy PDF while staged components (an AES decryptor, a downloader) install a repurposed MeshAgent remote-administration agent connecting to wss://boss-servers.gov.in.indianbosssystems.ddns[.]net:443/agent.ashx on AWS EC2 (Cyber Security News).
  • Root cause: user execution of a Linux .desktop file.
  • Attacker: not attributed; the .desktop technique and BOSS-themed C2 match earlier APT36 activity.
  • Response: IOCs published.
