Background for this topic.
LAPSUS$ is a name used in public reporting for an intrusion set associated with several high-profile compromises, particularly during 2021–2022. Investigations and victim disclosures linked the activity to social engineering, stolen credentials, account takeover—including reported abuse of help-desk or telecom recovery processes—and theft or attempted extortion of data and source code. Attribution, membership, and the relationship between individual incidents remain subject to change, so reports should be assessed for the evidence supporting each linkage.
Its security significance is the demonstrated exposure of identity and support workflows rather than reliance on a single malware family. Defenders should prioritize phishing-resistant multifactor authentication for privileged users, tightly control password resets and number-porting requests, limit administrator access, and monitor unusual identity-provider, cloud, and repository activity. After a suspected compromise, revoke sessions and tokens, rotate credentials and exposed secrets, preserve authentication and support-desk logs, and determine what data or code was accessed. These steps also help distinguish confirmed intrusion facts from claims made during extortion or incomplete early reporting.
Telecom company T-Mobile on Friday confirmed that it was the victim of a security breach in March after the LAPSUS$ mercenary gang managed to gain access to its networks
T-Mobile has confirmed that the Lapsus$ extortion gang breached its network "several weeks ago" using stolen credentials and gained access to internal systems. [...]
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$, whose obsession with stealing and leaking proprietary computer source code from the world’s largest tech companies ultimately led to the group’s undoing.
Companies must enforce more security on their own third-party providers and retain the ability to conduct independent investigations, experts say.
Identity and access management firm Okta says an investigation into the January Lapsus$ breach concluded the incident's impact was significantly smaller than expected. [...]
Identity and access management provider Okta on Tuesday said it concluded its probe into the breach of a third-party vendor in late January 2022 by the LAPSUS$ extortionist gang
