Despite the rise of cybersecurity infrastructure, the online identity still faces many risks, including those related to the hacks of one’s phone numbers.
In early July, LayerZero CEO Bryan Pellegrino became one of the latest victims of a SIM swap attack, which allowed hackers to briefly take over his Twitter.

A SIM swap hack is a form of identity theft where attackers take over a victim’s phone number, allowing them to gain access to bank accounts, credit cards or crypto accounts.

This represented a 400% increase in the number of complaints received in the three prior years, indicating that SIM swapping is “definitely on the rise,” CertiK’s director of security operations Hugh Brooks told Cointelegraph.
“If there is no move away from SMS-based 2FA and telecommunications providers do not lift their security standards, we are likely to see attacks continue to grow,” Brooks stated.
According to SlowMist chief information security officer (CISO) 23pds, SIM swapping is currently not too widespread, but it has a significant potential to rise further in the near future. He stated:

23pds mentioned a few cases involving SIM swap hacks in crypto over the past few years. In October 2021, Coinbase officially disclosed that hackers stole crypto from at least 6,000 customers due to a 2FA breach….
