Hackers discovered a flaw on the T-Mobile website that let them hijack customers’ personal information simply by plugging in phone numbers, according to Motherboard.
Last week, security researcher Karan Saini, of the security information site Secure7, found the vulnerability and informed T-Mobile of the glitch. T-mobile removed the flaw and offered Saini $1,000 as part of the company’s Bug Bounty program.
