TheGentlemen breaches Michigan IT services provider: Ransomware Claim — What’s Alleged & What To Do

On July 7, 2026, the threat actor known as thegentlemen listed Technical Solutions Group on a leak site and claimed responsibility for a data breach. The Michigan-based managed IT services and hosting provider has not confirmed the incident, and no details on the number of people affected, the volume of data, or the method of access have been made public. The listing raises the possibility that business records and client information held by the company were accessed without authorization. Because Technical Solutions Group provides services to other organizations, any exposure could extend beyond the company itself to its customers.

Inside the incident

The only confirmed information is the date of the leak-site posting and the identity of the organization named. No timeline for the intrusion, no description of how access was obtained, and no statement on whether data were exfiltrated or encrypted have been released by either the company or the group. The scale of the claimed breach remains unknown.

Who is thegentlemen?

Thegentlemen is a threat actor that posts claimed victim data on dedicated leak sites. Such groups typically announce incidents after they believe they have obtained files, often as part of extortion attempts. Public records of the actor’s prior listings show a pattern of targeting organizations that hold third-party data, though each claim must be evaluated separately because verification by independent sources is not always available.

About Technical Solutions Group

Technical Solutions Group operates as a managed IT services and hosting provider in Michigan. Companies in this sector commonly maintain client networks, store configuration data, and handle authentication credentials for the organizations they support. A breach at such a provider can therefore affect multiple downstream entities even when the initial target is a single firm.

The information in question

The types of data involved have not been disclosed. Organizations that deliver managed IT and hosting services routinely process business contact details, network diagrams, administrative credentials, and customer account records. Until Technical Solutions Group or a verified investigation publishes a list of exposed categories, the precise contents of any claimed dataset cannot be confirmed.

What's at stake

For individuals and client organizations, the main concerns are the potential reuse of credentials elsewhere and the exposure of internal business information that could aid further targeting. For Technical Solutions Group, the incident may prompt reviews of access controls and contractual obligations to notify customers. Both outcomes depend on facts that remain unavailable at this time.

Were you affected?

Technical Solutions Group has not published a notification process or a list of impacted parties. Individuals and organizations that used the provider’s services should monitor official statements from the company and consider the following immediate steps:

• Change passwords for any accounts associated with Technical Solutions Group services and enable multi-factor authentication where available.
• Review recent login activity on systems hosted or managed by the provider.
• Run a free exposure scan of your email address against known breach datasets to check for prior appearances of your information.

Further details may emerge if the company issues a formal statement or if additional verified reporting becomes available.
