CH Paper Listed by Deadlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On June 15, 2026, the Deadlock ransomware group listed Cheng Heng Paper Products Co (Pte) Ltd, operating as CH Paper, on its leak site. The listing asserts that internal files were exfiltrated during a ransomware attack. No confirmed count of affected individuals or specific file inventories has been released. The incident forms part of a broader pattern in which ransomware operators publicly claim compromises of manufacturing and supply-chain firms. Such listings often precede or accompany demands for payment, though the precise sequence and any ransom negotiations in this case remain undisclosed.

Inside the incident

Public reporting on the event is limited to the June 15, 2026 listing by Deadlock. The group claims to have removed internal files; no independent confirmation of the volume, type, or date range of the data has been published. The number of people whose information may be involved is not stated. Details on initial access method, dwell time, or whether encryption was deployed alongside exfiltration are also not available in open sources.

The group behind it: Deadlock

Deadlock is a ransomware operation that maintains a leak site to publish names of claimed victims. Like several other ransomware groups, it follows a double-extortion model in which data are copied before encryption and then threatened with disclosure if ransom demands are not met. The group has appeared in multiple public listings involving commercial targets across different regions. Its listing of CH Paper constitutes an unverified claim by the actor; no separate forensic report or victim statement has corroborated the assertion at the time of writing.

About CH Paper

Cheng Heng Paper Products Co (Pte) Ltd manufactures corrugated cardboard boxes and custom packaging solutions. It maintains production and distribution operations in Malaysia, Indonesia, and China, serving logistics, e-commerce, and retail customers with certified packaging products. Organisations of this type routinely store order records, supplier contracts, production schedules, and customer specifications as part of day-to-day operations.

The information in question

The only detail released is that internal files were allegedly exfiltrated. No inventory of specific data categories has been published. Manufacturing firms in this sector commonly retain customer contact information, shipment and order data, financial records tied to transactions, and technical specifications for packaging designs. The exact contents of the claimed exfiltration remain unconfirmed.

The real-world impact

Exposure of internal operational files can create secondary risks for business partners whose order details or design specifications appear in the material. Individuals whose contact or account information is present may face increased phishing or impersonation attempts. For the company, the listing itself can affect relationships with customers who require assurance about supply-chain security. No confirmed instances of misuse stemming from this listing have been documented publicly.

What to do if you're exposed

Individuals concerned about possible exposure should monitor their email accounts for unusual login attempts and enable multi-factor authentication on any services linked to the affected organisation. Passwords used for CH Paper-related accounts should be changed if reuse across other services is suspected. Readers may run a free exposure scan of their email address against known breach data sets to determine whether their information has appeared in previously published collections.
