What the listing means

Manhattan Fire Safety Corp appeared on the thegentlemen leak site on 06 May 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated. This group has published 134 claims in the last 30 days and remains active.

Recommended actions

  • Treat any unsolicited message referencing Manhattan Fire Safety Corp as suspicious — leaked data gets weaponised for phishing within days.
  • If you hold an account on mfsnyc.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
  • Other Business Services organisations should review this group's known TTPs and validate detection coverage against them.
  • Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
  • A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
