This Week’s Top Story

LastPass breach worse than previously thought

LastPass, a password management company, had a rough ending to 2022. Reason being, the company suffered a hack in August of last year, sharing that attackers had accessed LastPass’s development environment, taking portions of their source code and proprietary technical information. New details were then shared by the company in December of 2022 that hackers also stole vault data containing encrypted and unencrypted data from the company, including customer information. 

Now, ZDNet has shared the latest development on the LastPass breach, showing that it was more detrimental than previously thought. In a recent statement, the company said that hackers have used information stolen in the August 2022 attack, as well as other breaches and exploitations, to launch a second attack on LastPass. This new attack targeted a senior DevOps engineer at the company by compromising their home computer. This specific engineer had the required high-level authentication necessary to use the decryption keys required to access the company’s cloud storage service. 

According to ZDNet, the exact details of LastPass’s latest attack are not certain. However, the company did share that the engineer’s computer was attacked as a result of “a vulnerable third-party media software package.” This then allowed the attackers to install keylogger malware onto the engineer’s computer, which gave the hackers access to whatever the employee typed on their machine. By doing this, the attackers were able to steal the master password to gain access to LastPass’s corporate vault, “which contained encrypted secure notes with access and decryption keys needed to access the AWS S3 LastPass production backups, other cloud-based storage resources, and some related critical database backups,” according to the company.  

LastPass is now taking several security measures to handle the latest attack, and is urging both business administration users and general customers to change their master passwords.
