czkingdee.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
czkingdee.com was listed by the LockBit5 ransomware group on February 23, 2026, after internal files were exfiltrated. Anyone who may have had data held by the organisation should check for any follow-up notices and take steps to protect their information.
Inside the incident
The only public record of the event is the listing itself. It asserts that files were taken from czkingdee.com but supplies no further detail on the volume of data, the encryption status of systems, or whether any material was later published. Timing of the intrusion, the initial access method, and any ransom demand remain undisclosed.
Who is lockbit5?
Lockbit5 is one of several iterations of the LockBit ransomware operation, a group that has conducted numerous campaigns since 2019. The group typically uses double-extortion tactics: encrypting victim systems and threatening to release stolen files if payment is not made. It maintains a public leak site where it lists organizations it claims to have targeted. Such listings constitute an unverified assertion by the group and do not, by themselves, confirm the accuracy or completeness of the claimed compromise.
Who is czkingdee.com?
czkingdee.com is the online presence of Jiangsu Zhidie Digital Technology Co., Ltd., formerly known as Changzhou Kingdee. The company was established in 1999 and has operated for more than two decades as a partner of Kingdee Group, a major provider of enterprise management software. It is recognized by Jiangsu provincial authorities as a high-technology enterprise and an intelligent-manufacturing service organization. Its work centers on the deployment and support of business software systems used by other organizations.
What was likely exposed
The listing refers only to “internal files exfiltrated.” No inventory of specific data categories has been published. Organizations of this type routinely hold client records, project documentation, configuration files for software installations, and internal communications. The precise nature and sensitivity of the material taken in this case have not been confirmed.
Why it matters
Because czkingdee.com works with enterprise clients, any exposed files could contain information belonging to those clients as well as to the company itself. Potential consequences include unauthorized access to business processes, exposure of configuration details that could aid further intrusions, and the possibility that personal or operational data held on behalf of customers may have been copied. The absence of a confirmed data inventory leaves both the company and its clients without a clear picture of the risk.
What to do if you're exposed
Individuals or organizations concerned about possible exposure should monitor accounts for unusual activity, change passwords for any services linked to czkingdee.com, and enable multi-factor authentication where available. They can also run a free exposure scan of their email address against known breach data to determine whether their information appears in public listings from this or other incidents.

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.
