EquiLend back in the saddle as ransom payment rumors swirl

EquiLend, a major securities finance technology firm used by large Wall Street participants, experienced a disruptive ransomware attack attributed to LockBit; the company took systems offline, worked with third-party experts, and has since restored client-facing services while stating it has not identified evidence of client transaction data exfiltration. The report notes possible ransom negotiations (LockBit claimed responsibility but did not list the victim), highlights the platform's critical role (transacting ~$113.5B/day), and describes typical double-extortion risk, though operational impact was reportedly contained and recovery completed.
