Astreya Listed by coinbasecartel Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Astreya was listed by the coinbasecartel ransomware group on April 15, 2026, with internal files reported exfiltrated in the attack; the number of people affected has not been disclosed. Anyone who has done business with Astreya should review their accounts and monitor for unusual activity.
Breaking down the breach
The incident centers on a claim posted by coinbasecartel that it obtained internal files from Astreya. No confirmed timeline for the intrusion, volume of data, or method of access has been made public. The organization has not issued a statement confirming or denying the listing, and independent verification of the files' contents is not available at this stage.
Inside coinbasecartel
Coinbasecartel is a ransomware operator that maintains a public leak site where it lists organizations it claims to have targeted. Groups of this type commonly exfiltrate data before encrypting systems and then use the threat of publication to pressure victims. Their listings are presented by the group itself and are not independently verified unless the victim or law enforcement later confirms details. Prior activity by similar actors shows a pattern of targeting service providers that hold data on behalf of other companies.
Who is Astreya?
Astreya is a U.S.-based managed IT services company headquartered in Sunnyvale, California. It supplies technology workforce solutions, IT support, infrastructure management, and digital workplace services to large enterprises. The firm operates in the information technology services sector and maintains partnerships with major technology companies across multiple countries while keeping its primary operations in the United States.
What data was at risk
The listing identifies only “internal files” as having been exfiltrated. No further breakdown of file types, categories, or specific records has been released. Organizations in the managed IT services sector routinely hold client configuration data, support tickets, employee records, and network documentation, yet the exact contents tied to this claim remain unconfirmed.
What's at stake
Because Astreya provides services to large enterprises, any confirmed exposure of internal files could affect downstream clients whose systems or support records are referenced in those materials. Individuals whose information appears in support or staffing records face the standard risks associated with leaked internal documents, such as targeted phishing or account misuse. The organization itself may encounter operational disruption and reputational questions while the claim is investigated.
What to do if you're exposed
Monitor accounts linked to any email addresses that may have been used in dealings with Astreya or its clients. Enable multi-factor authentication where available and review recent login activity. Individuals can run a free exposure scan of their email address against known breach data to determine whether their information has appeared in public listings.

Publicly posted by coinbasecartel — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
