T-Mobile Austria admitted on Twitter that it stores at least part of their customer's passwords in plaintext. What this means is that "if anyone breaches T-Mobile (it's only a matter of time), they could likely guess or brute-force every user's password," reports Motherboard. "If the passwords were fully encrypted or hashed, it wouldn't be that easy. But having a portion of the credential in plaintext reduces the difficulty of decoding the hashed part and obtaining the whole password." From the report: "Based on what we know about how people choose their passwords," Per Thorsheim, the founder of the first-ever conference dedicated to passwords, told me via Twitter direct message, "knowing the first 4 characters of your password can make it DEAD EASY for an attacker to figure out the rest." T-Mobile doesn't see that as a problem because it has "amazingly good security." On Thursday, a T-Mobile Austria customer support employee made that stunning revelation in an incredibly nonchalant tweet. Twitter user Claudia Pellegrino was quick to point out that storing passwords in plaintext is wrong, but another T-Mobile customer rep didn't see it that way. "I really do not get why this is a problem. You have so many passwords for every app, for every mail-account and so on. We secure all data very carefully, so there is not a thing to fear," the rep wrote back.
