collinscomputing.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 30, 2025, the ransomware group lockbit5 listed collinscomputing.com on its leak site, stating that internal files had been exfiltrated during a ransomware attack. No information has been released about the number of individuals affected or the volume of data involved. The incident is one of many claims made by ransomware operators against technology and service providers that handle sensitive business records.

Public reporting on the event remains limited to the group’s listing. No confirmation from collinscomputing.com or independent verification of the data’s contents has been made available. The matter is therefore best understood as an unverified claim at this stage, with the practical consequences for any affected parties still unclear.

Inside the incident

The only confirmed detail is the date the listing appeared and the group’s assertion that internal files were taken. No timeline for the intrusion, method of initial access, or duration of the attackers’ presence inside the network has been disclosed. The number of records or files involved is also unknown.

Who is lockbit5?

LockBit is a ransomware-as-a-service operation that has been active for several years. The group typically supplies encryption tools to affiliates who carry out intrusions, then lists victim organisations on a public site when ransom demands are not met. Its listings function as a pressure tactic rather than verified proof of data possession. The appearance of collinscomputing.com on the site therefore represents the group’s claim rather than an independently confirmed breach.

Who is collinscomputing.com?

Collins Computing provides accounting software, with a focus on the Acumatica platform. Organisations in this sector routinely process financial records, customer billing information, and operational data on behalf of client businesses. A compromise at such a provider can therefore touch records belonging to many downstream companies even when the direct customer count remains unknown.

What was likely exposed

The listing refers only to “internal files exfiltrated in ransomware attack.” No further breakdown of file types or data categories has been published. Companies that supply accounting software commonly store client financial statements, transaction histories, user credentials, and configuration details; however, whether any of these specific categories were taken in this case remains unconfirmed.

What's at stake

Exposure of internal files from an accounting-software provider could allow unauthorised access to financial records belonging to client organisations. The main practical risks are identity misuse, fraudulent transactions, or targeted follow-on attacks against those clients. For the organisation itself, the incident may lead to remediation costs, regulatory scrutiny, and loss of customer trust, though the scale of these effects cannot yet be measured.

Were you affected?

Begin by monitoring official statements from collinscomputing.com for any guidance on notification or support. Individuals can also run a free exposure scan of their email address against known breach data sets to check whether their information has appeared in previously published incidents. Until more details are released, no further targeted actions can be recommended.
