Weak security measures in place at several major wireless carriers in the United States make it easy for attackers to perform SIM swap attacks on prepaid mobile accounts, a recent study found. In a SIM swapping attack, social engineering is used to convince a wireless services provider to hand over control of the victim's phone number by modifying the SIM card attached to the phone and mobile account.
Four Princeton University eggheads have published a report showing that the five major US mobile carriers implement weak authentication techniques, leaving customers vulnerable to SIM-swapping attacks that transfer victims' phone numbers to devices controlled by scammers. In a paper [PDF] titled, "An Empirical Study of Wireless Carrier Authentication for SIM Swaps," Kevin Lee, Ben Kaiser, Jonathan Mayer, and Arvind Narayanan looked at how AT&T, T-Mobile US, Tracfone, US Mobile, and Verizon Wireless handle requests to change the SIM card associated with mobile phone numbers.
Now, a cadre of lawmakers is demanding to know what the agency might be doing to track and combat SIM swapping. The lawmakers asked the FCC to divulge whether it tracks consumer complaints about fraudulent SIM swapping and number "Port-outs," which involve moving the victim's phone number to another carrier.
