![]() ![]() Other strong password practices, as per Microsoft, include: If a master password is reused and that password is compromised, a threat actor could use compromised credentials that are already available on the Internet to attempt account access (this is referred to as a “credential stuffing” attack). Customers should never reuse their master password.To further increase master password security, LastPass utilizes a stronger-than-typical implementation of 100,100 iterations of the Password-Based Key Derivation Function (PBKDF2), a password-strengthening algorithm that makes it difficult to guess a master password.This greatly minimizes the ability for successful brute-force password guessing. Since 2018, the company has required a twelve-character minimum for master passwords.LastPass communicated to all its users that: Performed an exhaustive analysis of every account to detect signs of any suspicious activity within the company’s cloud storage service.Actively rotated all relevant credentials and certificates that may have been affected and supplemented existing endpoint security.Added additional logging and alerting capabilities to help detect any further unauthorized activity.Replaced and further hardened developer machines, processes and authentication mechanisms.Eradicated any further potential access to the company’s development environment by decommissioning the environment and rebuilding a new environment from scratch.In response to the breach, according to the December statement, LastPass has: But if attackers compromise the master password, they will be able to successfully decrypt login credentials for all accounts stored in the password manager. Only a user’s master password potentially protects their credentials, which LastPass does not store. The breach puts LastPass customers’ login credentials at high risk. As a result, the intruders were able to exfiltrate customer vault data. This gave them access and the ability to decrypt storage volumes within the company’s cloud-based storage service. This allowed the intruders to obtain credentials and keys. LastPass stated that the source code and technical information originally stolen in August were used to target another employee. But just before Christmas, LastPass informed its users that hackers had indeed gained access to both encrypted customer information, including username, password and notes, as well as unencrypted data, such as the URLs of customers’ online accounts. Apparently, there was still no sign that customer data or passwords had been compromised. The situation took a turn for the worse at the end of November when LastPass CEO, Karim Toubba, disclosed that an unauthorized individual had obtained access to a third-party cloud storage device, compromising certain aspects of its customer information. Also, the unauthorized access was restricted to its development system, which is physically separated from its production environment. LastPass stated they discovered no additional indications of activity from the attacker. In September 2022, LastPass announced that it underwent a thorough investigation and forensic review of the breach with the help of incident response firm Mandiant. Apparently, there was no sign that the attack had compromised customer data or the encrypted password vaults. After this first breach, the company reassured its customers that they had contained the situation. This breach gave the attacker access to parts of the LastPass source code and proprietary technical information. In late August of 2022, LastPass announced that hackers had gained entry to parts of the company’s development environment through a compromised developer account. Now, in the wake of the LastPass breach, it might be worth revisiting this advice. For years, security experts have recommended the use of password managers. Password managers even remind you to renew your passwords periodically. A master password secures all data, which enables users to conveniently access all their passwords for other accounts. In addition, the situation ignited a wider conversation about the risks linked to utilizing password managers.Ī password manager helps users generate strong passwords and safeguards them within a digital locker. Some called into question the way LastPass handled and responded to the incident. In 2022, LastPass suffered a string of security breaches which sparked concern among cyber professionals and those impacted by the intrusions. ![]()
