The LastPass breach prompted Palant to investigate practices in this area among other password vault developers, uncovering shortcomings with Bitwarden’s approach in the process. Much worse yet, it had failed to migrate older accounts to even this suboptimal level, leaving them with just 5,000 rounds of protection. LastPass was faulted for applying fewer than the recommended number of iterations in hashing users’ encryption keys, performing only 100,000 in the best-case scenario. LastPass breach aftermath revisitedįailure to follow industry best practice on the number of hashing iterations becomes a live problem in the event of a password vault server breach, a calamity that recently befell LastPass. Hashing this password through an insufficient number of iterations leaves secrets at risk to potential brute-force attacks. Password vault data can only be decrypted using a key derived from a user’s master password.
In response to this blog post, a Bitwarden user claimed an account they started using in 2020 operated with just 5,000 iterations (adding that increasing the count to 200,000 failed to cause a “noticeable slowdown”). Palant posted a technical blog post on the issue on Monday (January 23). And, much worse, older accounts were stuck with much lower security settings (unless they manually increased iterations on their settings).Ĭatch up on the latest encryption-related security news and analysis But security researcher Wladimir Palant has warned that, while this might sound impressive, the server-side iterations are ineffective. In this scenario, OWASP recommends using the PBKDF2 algorithm with random salts, SHA-256, and 600,000 iterations (a figure recently increased from the previous recommendation of 310,00 rounds).īitwarden said that its data is protected with 200,001 iterations – 100,001 iterations on the client side and a further 100,000 on the server side. The issue centers on the number of PBKDF2 hash iterations used to compute the decryption key for a user’s password vault. UPDATED Password vault vendor Bitwarden has responded to renewed criticism of the encryption scheme it uses to protect users’ secret encryption keys by enhancing the mechanism’s default security configuration. You can access the shared information by just clicking the secure link.Password vault vendor accused of making a hash of encryption To access shared information, a recipient doesn't have to sign up for Bitwarden. But Bitwarden premium users can send any type of information, such as passwords, credentials, documents, files, and more.
BITWARDEN FREE
If you have a free Bitwarden account, you can share plain text information only. These features help you prevent unintentional information leaks. You can also set an expiration or deletion date.
You can set limits on how often the recipient can access the information by clicking the secure link. Limit Information Exposureīitwarden Send allows you to limit the exposure of your shared information. And for added security, you can password-protect the link too. With Bitwarden Send, you improve the confidentiality of information as the shared data is only accessible via a secure link. Bitwarden Send uses the 256-bit AES encryption method to ensure the security of shared information.
