![]() User data and the production environment were not breached according to the disclosure. It appears that the August 2022 security breach that LastPass disclosed had a limited scope. Depending on the service, other options may be available, including separating password databases. One of the best options includes implementing two-factor authentication. Users of the service, and any other online password management solution, should follow best practices to secure their accounts. Can the downloaded data be used to devise further attacks against the company or its users? LastPass fails to disclose additional details on the breach. Changes were announced to LastPass Free, the free plan of the password management service, that made some users migrate to other password management solutions, including Bitwarden and KeePass. In 2021, LastPass announced that it will become an independent company. The information included encrypted passwords, usernames and form-filled data. At that time, attackers managed to steal user data, including email addresses, password reminders, authentication hashes and other data was obtained. 22, 2022: Just before the holidays, in its most detailed update yet, LastPass said customer data was significantly compromised after an unknown threat actor copied a cloud-based backup of customer vault data. The August 2022 security breach is not the first such incident that LastPass disclosed. The app adds a second layer of authentication to the verification process. LastPass recommends that users follow best practices, which includes using the company's LastPass Authenticator application. The company's zero knowledge security model ensures that master passwords are secure, according to the company. LastPass notes in an FAQ that user data has not been compromised. It has not seen evidence of further unauthorized activity in the development environment or elsewhere. Containment and mitigation measures were deployed immediately and the company states that it has contained the breach and implemented additional security measures. LastPass hired a "leading cybersecurity and forensics firm" to investigate the breach. Products and services were not affected, and user data was not in danger at any point, according to the announcement. The threat actor managed to obtain "portions of source code and some proprietary LastPass technical information". An investigation confirmed that "an unauthorized party" gained access to parts of the development environment of the company this happened through a developer account that had been compromised. So what is a "weak password?" In the discussion section on the breach announcement, one LastPass employee explained that it's typically "single word passwords," like a name or anything that you would find in an English dictionary.According to the published information, LastPass noticed "unusual activity" about two weeks ago in the development environment. LastPass recommends users update weak master passwords immediately, and replace passwords on those other sites. With a weak master password, you're still in danger. That sounds good, but it's not good enough. ![]() It's also used on your PC or other device to turn your master password into your encryption key. PBKDF2-SHA256, a password-strengthening algorithm, effectively makes your LastPass master password harder to break with a brute-force attack. ![]() This additional strengthening makes it difficult to attack the stolen hashes with any significant speed. LastPass strengthens the authentication hash with a random salt and 100,000 rounds of server-side Password-Based Key Derivation Function-Secure Hash Algorithm] PBKDF2-SHA256, in addition to the rounds performed client-side. As for the stolen data, Siegrist wrote: We are confident that our encryption measures are sufficient to protect the vast majority of users.
