Hackers behind the T-Mobile hack that resulted in the theft of personal data belonging to over 54 million individuals have used brute-force attacks to infiltrate the mobile carrier's systems, FierceWireless reports.
"[T]he bad actor leveraged their knowledge of technical systems, along with specialized tools and capabilities, to gain access to our testing environments and then used brute force attacks and other methods to make their way into other IT servers that included customer data. In short, this individual's intent was to break in and steal data, and they succeeded," said T-Mobile CEO Mike Sievert, who also apologized for the massive breach.
Sievert also said that T-Mobile has entered long-term deals with Mandiant and KPMG to bolster its cybersecurity.
"Mandiant and KPMG will work side-by-side with our teams to map out definitive actions that will be designed to protect our customers and others from malicious activity now and into the future. I am confident in these partnerships and optimistic about the opportunity they present to help us come out of this terrible event in a much stronger place with improved security measures," Sievert said.
