The fraud known as SIM swapping is on the rise once again. Cybercriminals are manipulating telecom operators into transferring victims' phone numbers to SIM cards under their control, gaining unauthorized access to verification codes for bank accounts and social media.
Social engineering targeting support agents
A significant portion of these attacks relies on successful social engineering against telecom support agents. By leveraging previously stolen personal data, criminals convince representatives that they are speaking with the legitimate account holder.
Operators tighten verification processes
In response to the surge in SIM swap attacks, telecom providers are reinforcing identity verification protocols for SIM card replacement requests, though seasoned fraudsters still manage to exploit remaining security gaps.
Key warning signs to watch out for
A sudden and unexplained loss of mobile signal is one of the biggest red flags for this type of scam. Experts recommend contacting your carrier immediately if this happens, before hackers have a chance to compromise accounts tied to your number.
