You are using Opera browser με Opera Sync; Αλλάξτε άμεσα τον κωδικό πρόσβασής σας. Η εταιρεία έχει αρχίσει να επαναφέρει τους codeς πρόσβασης των χρηστών της υπηρεσίας Opera Sync. Είναι το feature που χρησιμοποιείται για να συγχρονίσει τους κωδικούς πρόσβασης, τις ρυθμίσεις και τα δεδομένα περιήγησης σε διαφορετικές συσκευές και εγκαταστάσεις του Opera.
In a post on the Opera blog, the company reports that the server using Opera Sync was violated earlier this week.
The company reports that an unknown attacker has been able to access Opera Sync systems and is afraid that some user data has been exposed. So he started restoring all passwords.
The incident is of major importance due to the nature of the data which are stored in the system. If an attacker gains access to a user's account, they will be able to access all of the victim's usernames and passwords for other services, their browsing history, bookmarks, and more.
If the user allowed Opera Sync to sync his passwords to other devices, this means that all of his passwords are available on Opera servers.
The company stated that all passwords for Opera Sync are hashed and salted, and the stored passwords from each user's accounts are encrypted.
If you are using this browser, with the Opera Sync feature you will need to change all the passwords you use on the web…. so to make sure your accounts are secure.
