Background for this topic.

Lapsus$ is a threat actor or intrusion set associated in public reporting with high-profile compromises, theft of corporate data and source code, and extortion through threats to disclose stolen information. Attribution can be difficult because the name may encompass activity by multiple individuals, so reporting should distinguish confirmed facts from claims made by the group or by investigators.

The material security concern is the exposure of identity and support processes: reported incidents have involved social engineering, compromised employee accounts, and access to cloud or development environments. Defenders should enforce phishing-resistant multifactor authentication where possible, tightly control help-desk account recovery, monitor unusual sign-ins and session use, and limit access to repositories and sensitive stores. If an intrusion is suspected, promptly preserve authentication and cloud logs, revoke sessions, rotate credentials and tokens, determine what data was accessed or removed, and assess privacy and notification obligations.

Leaked Chats Show LAPSUS$ Stole T-Mobile Source Code

KrebsOnSecurity recently reviewed a copy of the private chat messages between members of the LAPSUS$ cybercrime group in the week leading up to the arrest of its most active members last month. The logs show LAPSUS$ breached T-Mobile multiple times in March, stealing source code for a range of company projects. T-Mobile says no customer or government information was stolen in the intrusion. LAPSUS$ is known for stealing data and then demanding a ransom not to publish or sell it. But the leaked chats indicate this mercenary activity was of little interest to the tyrannical teenage leader of LAPSUS$, whose obsession with stealing and leaking proprietary computer source code from the world’s largest tech companies ultimately led to the group’s undoing.
