InvivoGen HK Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
InvivoGen HK has been listed by the sinobi ransomware group, which claims to have exfiltrated internal files. The listing was disclosed on January 11, 2026, and individuals connected to the organisation should check whether their data has been exposed and take appropriate protective steps.
Breaking down the breach
The incident was first noted through the group’s listing on January 11, 2026. Public information is limited to the claim that internal files were taken. No confirmed count of records, timeline of access, or description of the intrusion method has been disclosed. The organisation has not issued a separate statement confirming or denying the extent of the compromise.
The group behind it: sinobi
Sinobi is a ransomware operation that maintains a public leak site to list organisations it claims to have targeted. Such groups typically gain initial access through phishing, credential compromise or unpatched systems, then move laterally to locate and encrypt data before threatening publication. The current listing attributes activity against InvivoGen HK to this actor; that attribution rests on the group’s own claim rather than independent verification.
Who is InvivoGen HK?
InvivoGen HK operates in the biotechnology sector, specialising in microbial fermentation and the production of biological molecules. Its work includes ultra-pure antibiotics, mycoplasma treatments and collections of pattern-recognition receptor agonists derived from micro-organisms. Entities in this field routinely maintain records related to research protocols, proprietary strains, regulatory submissions and partner agreements.
What data was at risk
The listing refers only to “internal files” without naming specific categories. For a research organisation of this type, such files could include laboratory records, sequence data, client or collaborator information and internal correspondence. The precise contents remain unconfirmed, and no inventory of exposed data has been published.
The real-world impact
Exposure of internal research files could affect competitive positioning or regulatory standing if sensitive protocols or unpublished findings are involved. Individuals whose information appears in those files, such as research partners or staff, face the standard risks associated with any uncontrolled release of personal or professional records. The organisation must now manage potential regulatory notifications and remediation steps whose scope depends on the still-undisclosed details.
If your data was in this claimed breach

Publicly posted by sinobi — 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.
