The researchers aren’t advising anyone to avoid using password managers. “The OTP attack is a ‘targeted attack’ requiring an attacker to know the user’s username to potentially exploit it, and to serve that custom attack user activity which we have not seen,” LasPass aid. “Even if this was exploited, the attacker would still not have the key to decrypt user data.” “If you are concerned that you’ve used bookmarklets before September 2013 on non-trustworthy sites, you may consider changing your master password and generating new passwords, though we don’t think it is necessary,” said the company’s chief information officer Joe Siegrist. LastPass has issued a statement playing down the risk, stating that it issued a patch last September to fix these problems. The bug also gives attackers access to a user’s entire master password-encrypted vault. LastPass was also affected by a CSRF bug that allows attackers to see which devices and apps are running the software. An example of this might see an attacker setting up a fake banking website to trick those using bookmarklets to log in, giving up their password credentials. The flaw works if users are tricked into running Java on the attacker’s website. In LastPass, the researchers discovered a vulnerability in the bookmarklet option that permits integration with iOS’s Safari browser. The researchers noted that the root causes of the vulnerabilities are also diverse – these range from authorization and logic mistakes to misunderstandings about web security models, and more typical vulnerabilities like XSS (Cross site scripting) and CSRF (cross site request forgery). “We find vulnerabilities in diverse features like one-time passwords, bookmarklets, and shared passwords. “Our attacks are severe: in four out of the five password managers we studied, an attacker can learn a user’s credentials for arbitrary websites,” wrote researchers Zhiwei Li, Warren He, Devdatta Akhawe, and Dawn Song wrote in their paper. They described their work as a “wake-up call” for password manager developers. University of California Berkeley researchers have discovered a number of quickly-patched vulnerabilities in LastPass, My1Login, NeedMyPassword, PasswordBox and RoboForm. If you’re using a popular password manager your credentials might not be entirely safe, following the discovery of several vulnerabilities that could allow attackers to gain access.
