      Customer service agents see only parts of customers‘ passwords which are safely stored in encrypted databases via industry standard encryption algorithm. We are also using one-time-PINs for customer authentication and are evaluating voice biometrics. ^Helmut @ojour

          It is not secure for a verifier to store passwords in encrypted form. The moment you have both a ciphertext and the corresponding key stored, a breach of both will reveal the cleartext of the passwords.

          Käthe verliert ihren Job nicht. Die Antwort war in der Hitze eines Twitter-Threads offensichtlich nicht klug. Die Mischung aus Häme, Hetze und „Feuert Sie“, die dafür aus manchen Tweets kamen, sind hingegen erschreckend.

          I don't think she should be fired, however a PR job clearly isn't her cup of tea. Imagine someone received a clearly rancid cut of meat at a restaurant, and the manager dismissed any concerns with empty platitudes like "we take the freshness of our ingredients very seriously."

          Two-way encryption is in no way an industry standard for storing passwords. it's an embarrassment.

          Replying to @codingcatgirl @tmobileat and

          FYI, there's no such thing as a "one-way encryption." Encryption implies an ability to decrypt. Hashing is one-way. Saying "two-way encryption" just sounds redundant, and comes off like you have no clue what you're talking about.

          thanks mr. mansplainer. i knew that already, your wise guy correction behaviour was not needed, i just didn't fit a complete detailed pamphlet about how cryptographic hash functions work into my tweet. go be an obnoxious pedant somewhere else, bye

          So then why would you say two-way hashing? Sounds pretty ignorant, but looking at your Twitter profile, you seem like a typical Eurodiot... so nothing unusual there. "Does stuff with IT Security" is actually very alarming. Shouldn't people that do know what they're saying?

          Pretty much me to you. Listen, little "girl." Don't play with things that you shouldn't be playing with. Leave security to those that know what they're doing and what they're talking about. I just hope that no one trusts you to run actual security on a business level...

          You store the passwords encrypted, and the decryption key is available both on the server for http://mein.t-mobile.at  (Nice error page btw: http://keinzugriff.t-mobile.at/403.html?error_id=amazingly_good …) and on the customer care backend servers (for verification)?

          Two valid responses here 1. We don't care about customers' security, GDIAF 2. We apologize for putting our customers at risk and will be switching to *hashed* password as soon as possible There is no option 3. There is no such thing as a "safely encrypted password"

          It doesn't matter how secure you think your encryption on your database is. Storing any part of a password in plaintext is illegal in many industries- and there's a reason. You guys might want to start assuming you are unemployed. Your bad Opsec team as well.pic.twitter.com/Vg4CVgAvlO

          sounds to me like you are storing cleartext passwords in an encrypted database? You understand that a SQL injection issue could still lead to a massive breach of cleartext creds right?
