Password management service LastPass confirmed a security incident that resulted in the theft of certain source code and technical information.
The security breach is said to have occurred two weeks ago, targeting its development environment. No customer data or encrypted passwords were accessed, although the company provided no further details regarding the hack and what source code was stolen.
"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," LastPass CEO Karim Toubba said.
Amidst ongoing investigation into the incident, the company said it has engaged the services of a leading cybersecurity and forensics firm and that it has implemented additional countermeasures.
LastPass, however, didn't elaborate on the exact mitigation techniques that it used to strengthen its environment. It also reiterated that the break-in had no impact on users' master passwords, adding there is no evidence of further malicious activity.
As of now, no action is required from the side of users. LastPass claims over 33 million active users and more than 100,000 business accounts.
