LastPass Says Source Code Stolen in Data Breach

Password management software firm LastPass has suffered a data breach that led to the theft of source code and proprietary technical information.

The company, which is owned by GoTo (formerly LogMeIn), disclosed the breach in an online notice posted Thursday but insisted that the customer master passwords or any encrypted password vault data were not compromised.

LastPass chief executive Karim Toubba said the company’s security team detected unusual activity within portions of the LastPass development environment two weeks ago and launched an investigation that confirmed the source code theft.

From the LastPass notice:

We have determined that an unauthorized party gained access to portions of the LastPass development environment through a single compromised developer account and took portions of source code and some proprietary LastPass technical information. Our products and services are operating normally.

In response to the incident, we have deployed containment and mitigation measures, and engaged a leading cybersecurity and forensics firm. While our investigation is ongoing, we have achieved a state of containment, implemented additional enhanced security measures, and see no further evidence of unauthorized activity.

Dear valued customer,

We are writing to inform you that we recently detected some unusual activity within portions of the LastPass development environment. We have determined that an unauthorized party gained access to portions of the LastPass development environment through a single compromised developer account and took portions of source code and some proprietary LastPass technical information. We have no evidence that this incident involved any access to customer data or encrypted password vaults. Our products and services are operating normally.

In response, we immediately initiated an investigation, deployed containment and mitigation measures, and engaged a leading cybersecurity and forensics firm.

Re: LastPass Says Source Code Stolen in Data Breach

LastPass says the attacker behind the August security breach had internal access to the company's systems for four days until they were detected and evicted.
[...]

In the letter sent to customers after BleepingComputer's emails, Lastpass confirmed it was hacked two weeks before and that the attackers had stolen some source code and proprietary technical information.

"Two weeks ago, we detected some unusual activity within portions of the LastPass development environment," the company said at the time.

"After initiating an immediate investigation, we have seen no evidence that this incident involved any access to customer data or encrypted password vaults."

LastPass provides one of the most popular password management software in the world, with the company claiming that it's used by over 33 million people and 100,000 businesses.
