Avery Dennison Listed by coinbasecartel Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Avery Dennison was listed by the coinbasecartel ransomware group on November 13, 2025, after internal files were exfiltrated in an attack whose timing has not been established. Individuals who may have had dealings with the company should review any communications from Avery Dennison or their own accounts for signs of exposure and follow recommended security steps.
Inside the incident
The only confirmed information is the listing itself. Avery Dennison was added to the group’s site on the reported date, with the claim that files were removed from the company’s systems. No timeline for the intrusion, method of access, or confirmation of encryption has been released by either the company or investigators. The scale of any data removal is also undisclosed.
The group behind it: coinbasecartel
Coinbasecartel is a ransomware operation that maintains a public leak site to advertise claimed victims. Such groups commonly employ double-extortion tactics, first encrypting systems and then threatening to publish stolen material unless payment is made. The listing of Avery Dennison constitutes the group’s claim; independent verification of the data’s authenticity or the circumstances of its acquisition has not been provided.
Avery Dennison and its sector
Avery Dennison Corporation manufactures and distributes pressure-sensitive materials used in labeling, packaging, and graphics across global supply chains. Its Label and Graphic Materials segment produces items that support product identification and compliance in industries ranging from consumer goods to logistics. Organizations in this sector routinely manage production records, supplier information, and customer specifications that can contain commercially sensitive details.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been released. Companies of this type commonly hold records related to manufacturing processes, client contracts, and employee or partner contact information, yet the precise contents in this case remain unconfirmed.
What's at stake
Exposure of internal operational files can create competitive or regulatory risks for the organization and may indirectly affect business partners whose information appears in those records. Individuals named in any personnel or contact data could face increased phishing or social-engineering attempts, though the absence of confirmed data types makes the scope of personal impact difficult to assess at present.
Were you affected?
Begin by monitoring official statements from Avery Dennison for any notification process. Individuals can also review recent account activity for unusual access attempts and consider enabling multi-factor authentication on services that may share contact details with the company.

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.
