Following the recent hack of Adobe, resulting in millions of user IDs being stolen, Facebook has launched a new security feature. The users that are suspected to be endangered by Adobe passwords theft are required to prove their Facebook account ownership by answering several personal security questions and changing password. Having the same login details for all your online accounts may seem convenient but is not by far the wisest decision one may make. After recent hack of Adobe – software Development Company that presented us Photoshop and Flash plug-in long with Acrobat reader – more than 38 million of account details were stolen, as Adobe representative acknowledged. For many users having Facebook account means nearly the same as having your passport. Thus said, stolen details may match Facebook accounts, resulting in a possible huge security breach in Facebook. Facebook security team prevents hack attempts To prevent such unfortunate turn of events Facebook implemented additional security check for the accounts which email addresses match with the stolen from Adobe ones, and which are, therefore, compromised. Every account holder endangered by this hack now will see the warning message while trying to log to Facebook. The message states that account is temporarily blocked to prevent possible malicious activity. To gain access to it the holder should answer several personal questions and update the password. While no malicious activity from such accounts have not been reported yet, both Adobe and Facebook recommend every user checking their accounts and updating passwords to be on the safe side. This process is fully automated to increase the speed of updates, and to assist all customers in the most efficient way. This procedure works by taking the unencrypted Adobe account password and running it through special “hashing” script, which replaces plaintext password with alphanumerical sequence of symbols. This record becomes absolutely unrecognizable and allows avoid keeping the real password in the database in any form. Though this process is irreversible, the same passwords will also result in the same character sequences after hashing. This feature allowed Facebook security checking their account database for entries that corresponded with the hacked Adobe accounts and had overlapping email addresses. After finishing this process Facebook security ensured their increased efficacy in protecting their customer’s account details. Another outcome of Facebook hack attempts – MacRumors.com were hacked Additional information was revealed recently. MacRumors.com, website dedicated to discussions and speculations on Apple products was reported to be hacked. Its administrator advised 860, 000 users to change their passwords to prevent their accounts from being stolen. Despite using a kind of hashing technology, the database seems to be breached, proving earlier security measures being not efficient enough. These series of breaches are a warning for all Internet users preferring to have the same logins and passwords throughout all of their accounts. This greatly simplifies the hacker’s job, as hacking one of the logins reveals the whole array of user details to him. There currently are two alternatives – using a multitude of different logins and passwords for each of your online accounts and storing them offline – on your home PC/laptop or even in a notebook. On the other hand, one can use some kind of password storing tool that guards all account details by master password and auto-fills the forms during login. The latter is more preferable but less safe. Stay aware and stay safe!
