A Researcher Figured Out How to Reveal Any Phone Number Linked to a Google Account


Phone numbers are a goldmine for SIM swappers. A researcher found how to get this precious piece of information through a clever brute-force attack.

“I think this exploit is pretty bad since it's basically a gold mine for SIM swappers,” the independent security researcher who found the issue, who goes by the handle brutecat, wrote in an email. SIM swappers are hackers who take over a target's phone number in order to receive their calls and texts, which in turn can let them break into all manner of accounts. From there, the hacker can request password reset text messages, or multi-factor authentication codes, and log into the victim’s valuable accounts.
