New FCC Robocall Rule Could Accidentally Make SIM-Swap Attacks Easier — Here's Why Crypto Holders Should Care
52d ago · 1 source
A new FCC rule designed to combat robocalls may inadvertently create new vulnerabilities in phone account security. The regulation could make it easier for attackers to exploit phone accounts, which are often used as a key layer of security for cryptocurrency wallets and exchanges. Security experts warn that crypto holders who rely on SMS-based two-factor authentication could be particularly at risk.
WHY IT MATTERS
Think of your phone number like a master key to many of your online accounts — including crypto exchanges. When you log in somewhere and get a text message with a code, that's your phone number acting as proof of your identity. A 'SIM-swap attack' is when a hacker tricks your phone company into giving them control of your number, so they receive those codes instead of you. This new FCC rule, which was meant to stop annoying spam calls, might accidentally make it easier for hackers to pull off these tricks. If you hold crypto and use text messages as your security backup, this is a wake-up call to switch to more secure options like authentication apps (such as Google Authenticator), which work on your physical device and can't be hijacked through your phone carrier.
