Removed the development environment and rebuilt a new one to ensure full containment and eradication of the threat actor.As part of the containment, eradication, and recovery process, we took the following actions: In response to the first incident, we mobilized our internal security teams, as well as resources from Mandiant. We declared this incident closed but later learned that information stolen in the first incident was used to identify targets and initiate the second incident. No customer data or vault data was taken during this incident, as there is no customer or vault data in the development environment.

Incident 1 Summary: A software engineer’s corporate laptop was compromised, allowing the unauthorized threat actor to gain access to a cloud-based development environment and steal source code, technical information, and certain LastPass internal system secrets. There has been no contact or demands made, and there has been no detected credible underground activity indicating that the threat actor is actively engaged in marketing or selling any information obtained during either incident. To date, however, the identity of the threat actor and their motivation remains unknown. We have shared technical information, Indicators of Compromise (IOCs), and threat actor tactics, techniques, and procedures (TTPs) with law enforcement and our threat intelligence and forensic partners. Rather, the threat actor exploited a vulnerability in third-party software, bypassed existing controls, and eventually accessed non-production development and backup storage environments. Neither incident was caused by any LastPass product defect or unauthorized access to – or abuse of – production systems. The two incidents that we disclosed last year affected LastPass and our customers.

In sharing these additional details today, and in our approach going forward, we are determined to do right by our customers and communicate more effectively. The length of the investigation left us with difficult trade-offs to make in that regard, but we understand and regret the frustration that our initial communications caused for both the businesses and consumers who rely on our products.
We have heard and taken seriously the feedback that we should have communicated more frequently and comprehensively throughout this process.
