8/9/2023 0 Comments Lastpass hacker news![]() ![]() LastPass has a RECOMMENDATION of 100,000 but it isn’t a default. They also add another 100,000 iterations on the server making it 200,001. ![]() Note, this isn’t an issue in this LastPass breach but just an indication of the poor software that is LastPass.įourth, Bitwarden default local iteration count used with PBKDF2 is 100,001. Furthermore, the vault recovery key and dOTP are stored on each device in plain text, rendering the master password useless. The entire vault is decrypted once and stored entirely in memory. LastPass vault encryption key is always resident in memory and never wiped. Third, Lastpass has poor local encryption management. Anyone that has a LastPass vault can view which websites have an account and target individuals based on that info even if the password is later changed. This makes a LastPass user vulnerable to phishing even if the hacker does not crack the password. Nearly everything in the LastPass vault is unencrypted. Second, Bitwarden’s entire vault is encrypted. More transparency and more eyes to review it. Open source means that anyone can look at the source code and view it for weaknesses. As opposed to LastPass closed source software. A few of the reasons Jim and I chose Bitwarden over LastPass is that Bitwarden has security advantages over LastPass.įirst, it is open source software. By September, Lastpass publicly announced the vulnerability, acknowledging the issue and patched all platforms.Īs Jim has mentioned, to date there has been no known breach of Bitwarden. On August 30, 2019, a vulnerability was found in the LastPass browser extension where websites with malicious JavaScript code could obtain a username and password inserted by the password manager on the previously visited site. On March 25, an additional security flaw was discovered allowing remote code execution based on the user navigating to a malicious website. The exploit applied to all LastPass clients, including Chrome, Firefox, and Edge. On March 20, 2017, a vulnerability in the LastPass Chrome extension was discovered. LastPass was notified privately and fixed their browser extension. In July 2016, due to poorly written URL parsing code in the LastPass extension, a method was found for reading plaintext passwords for arbitrary domains from a LastPass user’s vault when that user visited a malicious website. Therefore, LastPass recommends changing stored website passwords. However, if the customer did not follow LastPass best practices, it would “ significantly reduce the number of attempts needed to guess” the master password correctly. LastPass claims that their hashing and encryption methods would make it difficult to guess the master password if the customer followed LastPass best practices. ![]() However, according to LastPass, the “threat actor” can use brute force to guess the master password and decrypt the copies of the vault data that they took. LastPass states that encrypted fields remain secure and can only be decrypted with a unique encryption key derived from each user’s master password using their Zero-Knowledge architecture. The “threat actor” was also able to copy customer vault data that contains both unencrypted data, such as website URLs, as well as encrypted fields such as website usernames and passwords, secure notes, and form-filled data. LastPass claims that there is no evidence that any unencrypted credit card data was accessed. Now, LastPass is announcing that the “unknown threat actor” leveraged the technical information from the August breach to target an employee in obtaining credentials and keys able to access and decrypt “ storage volumes within the cloud-based storage service”. The “threat actor” used the keys to copy information from backups that contained basic customer account information including company names, end-user names, billing addresses, email addresses, telephone numbers, and the IP addresses that customers were using to access the LastPass service. ![]() Their investigation determined an unauthorized party, using information obtained in the August 2022 incident, was “ able to gain access to certain elements of our customers’ information”. On November 30, LastPass announced that they detected unusual activity within a third-party cloud storage service, shared by both LastPass and its affiliate, GoTo. In August, LastPass announced that attackers were able to steal source code and proprietary technical information. The announcement confirms that the user vault data was also obtained. On December 22, Karim Toubba, the CEO of LastPass, announced that the LastPass breach is more severe. On November 30, LastPass reported that they were breached and an unauthorized party, using information obtained in the August 2022 incident, was “ able to gain access to certain elements of our customers’ information”. ![]()
