Twitter's official support channel posted a tweet asking users to change their precautions codetheir
The tweet does not mention details, but a post on blog της εταιρείας αναφέρει ότι οι προγραμματιστές ανακάλυψαν ένα σφάλμα που επέτρεπε την αποθήκευση κωδικών πρόσβασης "unmasked", δηλαδή χωρίς κάποια κρυπτογράφηση, σε μορφή απλού κειμένου.
Shortly after the tweet we received a warning email asking for exactly the same. You can see the email at the end of the post.
Twitter - Τι έγινε
Συνήθως, το twitter χρησιμοποιεί έναν ισχυρό αλγόριθμο κατακερματισμού (bcrypt) για να αντικαταστήσει γράμματα και αριθμούς στους κωδικούς πρόσβασης με μια φαινομενικά άσχετη σειρά χαρακτήρων που "σκεπάζει" τους πραγματικούς. Το hashing επιτρέπει τη χρήση των διαπιστευτηρίων σας για τη σύνδεση στο Twitter και άλλες υπηρεσίες, χωρίς να αποκαλύπτει τους κωδικούς πρόσβασης που χρησιμοποιείτε σε προγραμματιστές ή διαχειριστές συστημάτων.
Due to an error, the passwords before being hashed with bcrypt were written in plain text, revealing the passwords to the Twitter developers.
Twitter states that they themselves noticed the error and that the service has not been violated.
Note that if you use the same password on other services, change it immediately.

Hi @ iGuru_gr, |
|
When you set a password for your Twitter account, we use the technology that masks it so no one at the company can see it. We recently identified a bug that stored the unmasked passwords in an internal log. We have fixed the bug, and our investigation shows no indication of breach or misuse by anyone. |
|
Out of an abundance of caution, we ask that you consider changing your password on all services where you've used this password. You can change your Twitter password anytime by going to the password settings page. |
|
About The Bug |
|
We mask passwords through a process called hashing using a function known as bcrypt, which replaces the actual password with a random set of numbers and letters that are stored in Twitter's system. This allows our systems to validate your account credentials without revealing your password. This is an industry standard. |
|
Due to a bug, the passwords were written to an internal log before completing the hashing process. We found this error ourselves, removed the passwords, and are implementing plans to prevent this bug from happening again. |

Tips on Account Security |
|
Again, although we have no reason to believe password information ever left Twitter's systems or was misused by anyone, there are a few steps you can take to help us keep your account safe: |
|
1. |
|
Change your password on Twitter and on any other service where you may have used the same password. |
2. |
|
Use a strong password that you don't reuse on other services. |
3. |
|
Enable login verification, also known as two factor authentication. This is the best single action you can take to increase your account security. |
4. |
|
Use a password manager to make sure you're using strong, unique passwords everywhere. |
|
|
We are very sorry this happened. We recognize recognize and appreciate the trust you place in us, and are committed to earning that trust every day. |
