Computing Dynamics Listed by interlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 9, 2025, the ransomware group interlock listed Computing Dynamics on its leak site, claiming to have carried out a ransomware attack against the company. Public information about the incident remains limited to that listing and the assertion that internal files were taken. The number of individuals affected has not been disclosed. The incident occurs against a backdrop in which ransomware operators routinely combine encryption with data theft and then use public leak sites to pressure victims. Such listings have become a standard element of many campaigns, shifting some of the response burden onto the affected organisation and any third parties whose information appears in the stolen material.

Breaking down the breach

Available details state only that Computing Dynamics was listed by interlock and that internal files were exfiltrated during a ransomware attack. No confirmation of the volume of data, the encryption status of systems, or any ransom demand has been made public. The number of people whose information may be involved is reported as unknown.

Inside interlock

Interlock is a ransomware group that maintains a leak site to publish data taken from victims. Like several other operators active in recent years, the group typically advertises successful intrusions by posting sample files and organisation names. Its listings function as a form of public pressure rather than verified proof of the claims made about any specific incident.

Computing Dynamics and its sector

Computing Dynamics develops custom software and supplies IT services to clients. Organisations in this sector routinely hold records relating to their own operations as well as information belonging to the businesses and individuals they support. A compromise at such a firm can therefore extend beyond the company’s own perimeter to affect downstream customers and staff.

What was likely exposed

The only data type explicitly referenced in connection with the listing is internal files exfiltrated during the ransomware attack. The group’s accompanying statement claims that material concerning clients, employees and the company itself was taken, including names, phone numbers, addresses and other personal details. These descriptions remain unverified claims; the precise contents of any exfiltrated files have not been independently confirmed.

What's at stake

Individuals whose contact or personal information appears in the material face the ordinary risks associated with exposed directory data, such as increased exposure to unsolicited contact or attempts at social engineering. For the organisation, the incident adds the task of assessing what was taken, notifying affected parties where required, and reviewing access controls around client and employee records.

Were you affected?

Begin by monitoring official communications from Computing Dynamics. Individuals can also enter their email address into a free exposure-checking service to see whether it appears in any previously published breach datasets. Further steps, such as reviewing account security and watching for unusual activity, follow standard practice after any reported incident involving personal or business contact information.
