CH Paper Listed by Deadlock Ransomware Group

On June 10, 2026, Cheng Heng Paper Products Co (Pte) Ltd appeared on the leak site of the Deadlock ransomware group. The Singapore-based manufacturer of corrugated cardboard boxes and custom packaging, which operates across Malaysia, Indonesia, and China, is claimed to have had internal files exfiltrated following a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, any current or former employees, customers, or business partners whose details were stored in the compromised systems could be affected.

What's Publicly Reported from Reporting

Public reporting indicates that Deadlock posted data stolen from Cheng Heng Paper on its leak site on June 10, 2026. The company supplies certified packaging solutions for logistics, e-commerce, and retail customers throughout Southeast Asia and China. Available reporting describes the incident as a ransomware attack in which attackers exfiltrated internal files before encrypting systems or demanding payment. No confirmed total of records or specific victim count has been released by the company or the group.

Internal files were taken, though the precise data types have not been fully detailed in public leaks. Industry research from sources such as DoxxScan™ continuous monitoring indicates that manufacturing and logistics firms routinely store employee personal information, supplier contracts, customer orders, and financial records — any of which may now be in attackers’ hands.

Why This Matters for You and Your Family

When a company like Cheng Heng Paper suffers a breach, the ripple effects reach ordinary people. If you have ever worked there, bought their packaging, or had your information shared through a supplier or partner, your details could be exposed. That might include names, addresses, contact numbers, email accounts, or payment information.

For your family this means heightened risk of identity theft, phishing campaigns, or fraudulent loan applications. Children’s records, sometimes included in employer family-health or dependent files, can also surface. Once personal data leaves a corporate system, it rarely stays contained. Attackers sell or publish it, and other criminals reuse it for months or years.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently contain more than isolated records. They can link email addresses to employee IDs, phone numbers to home addresses, and vendor contacts to broader networks. These connections let attackers build an identity chain that moves from one compromised account to the next. A work email leaked today can unlock personal accounts tomorrow if passwords were reused.

Credential leaks like this one cascade into account takeovers and doxxing chains, especially when gaming usernames or family member details appear alongside adult records. Public reporting shows that ransomware operators increasingly harvest any information that can be monetized through extortion or sold on underground forums.

Deadlock Ransomware Group Track Record

Public reporting attributes the attack to the Deadlock ransomware group. The group emerged in late 2024 and has targeted organizations across multiple sectors since then. Notable prior victims include manufacturing, logistics, and technology companies whose data appeared on the same leak site. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by exfiltration of sensitive files and deployment of ransomware. They then pressure victims with threats to publish stolen data unless a ransom is paid, often setting short deadlines measured in days.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what this claimed breach connects to.
• Rotate any password you used at Cheng Heng Paper or any supplier portal connected to it, then enable 2FA through an authenticator app instead of SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours rather than months.
• Cover the household with DoxxScan family coverage that includes dependents and your children’s gaming accounts, which often chain back to the same addresses and parent emails leaked in corporate files.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing day-to-day accounts.
