Polish authorities arrested four people accused of stealing millions by hijacking victims’ phone numbers and taking over their cryptocurrency accounts. Investigators say the group breached entities working with telecommunications operators and compromised employee email accounts using software and social engineering, then intercepted SMS messages and email traffic to conduct SIM-swapping attacks; the operation involved support from the FBI and Homeland Security Investigations.
Why it matters: SIM swapping can let criminals bypass text-message security codes and seize control of email, financial, and crypto accounts. Telecom-adjacent organizations should review partner access and employee email protections, and users should move high-value accounts away from SMS-based authentication where possible.
