Deck India Engineering Pvt. Ltd was listed by the tengu ransomware group on January 19, 2026, after internal files were exfiltrated in a ransomware attack. Anyone who has interacted with the company should check their status and take protective steps.
Breaking down the breach
The only confirmed information is the listing itself and the reference to exfiltrated internal files. No date of the attack, volume of data, or technical details have been disclosed. The reported summary provides no additional information on how the incident occurred or was discovered.
The group behind it: tengu
Tengu is a ransomware group that maintains a leak site where it lists organizations it claims to have targeted. Such groups typically gain access through common intrusion methods, encrypt systems, and then publish victim names along with samples of stolen data to pressure payment. The listing of Deck India Engineering Pvt. Ltd. is presented as a claim by the group; no independent confirmation of the underlying incident has been reported.
Who is Deck India Engineering Pvt. Ltd?
Deck India Engineering Pvt. Ltd. was established in Pune in 1998 and provides heat treatment services such as Liquid Nitriding, Nitro Carburising, and Gas Nitriding. It serves clients across Maharashtra and other regions, and it also manufactures and supplies heat treatment equipment and furnaces. The company describes itself as the first SSI unit in its area focused on these processes, with a management team of engineers and metallurgists.
What data was at risk
The listing refers only to internal files. No specific categories of data, such as customer records, employee information, or technical documents, have been identified. Organizations in the industrial services sector commonly hold client contracts, process specifications, equipment designs, and personnel records, but the exact contents of the exfiltrated files remain unconfirmed.
The real-world impact
Exposure of internal files can create operational and competitive concerns for the company and may affect clients whose information appears in those files. Individuals whose personal details are present in any exfiltrated records face the standard risks associated with data appearing in unauthorized hands, including potential misuse for fraud or further targeting. No specific harms have been documented at this stage.

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.
