Lastpass data breach reddit11/10/2023 ![]() ![]() It bears noting at this stage that the success of the brute-force attacks to predict the master passwords is inversely proportional to their strength, meaning the easier it is to guess the password, the lesser the number of attempts required to crack it. The company did not divulge how recent the backup was, but warned that the threat actor "may attempt to use brute-force to guess your master password and decrypt the copies of vault data they took," as well as target customers with social engineering and credential stuffing attacks. LastPass confirmed that the security lapse did not involve access to unencrypted credit card data, as this information was not archived in the cloud storage container. These fields, the company explained, are protected using 256-bit AES encryption and can be decoded only with a key derived from the users' master password on the users' devices. It's stored in a "proprietary binary format" that contains both unencrypted data, such as website URLs, and fully-encrypted fields like website usernames and passwords, secure notes, and form-filled data. On top of that, the adversary is said to have copied customer vault data from the encrypted storage service. LastPass said this permitted the unidentified attacker to obtain credentials and keys that were subsequently leveraged to extract information from a backup stored in a cloud-based storage service, which it emphasized is physically separate from its production environment. The August 2022 incident, which remains a subject of an ongoing investigation, involved the miscreants accessing source code and proprietary technical information from its development environment via a single compromised employee account. The popular password management service on Thursday revealed that malicious actors obtained a trove of personal information belonging to its customers that include their encrypted password vaults by using data siphoned from the earlier break-in.Īmong the data stolen are "basic customer account information and related metadata including company names, end-user names, billing addresses, email addresses, telephone numbers, and the IP addresses from which customers were accessing the LastPass service," the company said. ![]() This should provide additional security, “more robust authentication and login-based security options.The August 2022 security breach of LastPass may have been more severe than previously disclosed by the company. Furthermore, the company is migrating customer accounts onto an enhanced Identity Management Platform. Out of an abundance of caution, GoTo will reset all passwords and reauthorize MFA settings. GoTo is already contacting impacted customers with additional information and recommendations to secure their accounts. “In addition, while Rescue and GoToMyPC encrypted databases were not exfiltrated, MFA settings of a small subset of their customers were impacted.” “The affected information, which varies by product, may include account usernames, salted and hashed passwords, a portion of Multi-Factor Authentication (MFA) settings, as well as some product settings and licensing information,” Srinivasan said about the GoTo security breach. Moreover, the hackers downloaded an encryption key for a portion of the encrypted backups. “Our investigation to date has determined that a threat actor exfiltrated encrypted backups from a third-party cloud storage service related to the following products: Central, Pro,, Hamachi, and RemotelyAnywhere,” the blog post reads. On Tuesday, GoTo CEO Paddy Srinivasan updated the announcement, detailing the massive breach that impacted other GoTo services. LastPass parent company GoTo also posted a notice about the security incident in November. LastPass disclosed the turn of events on the Thursday before Christmas. The hackers weaponized information from the August hack to steal LastPass data in November. LastPass first disclosed the security breach in August 2022, expanding on the matter in November. ![]()
