Semaphore Solutions Inc Listed by onyx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Semaphore Solutions Inc Listed by onyx Ransomware Group (reported April 29, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
Semaphore Solutions Inc was listed on the leak site operated by the onyx ransomware group on or before April 29, 2022. The listing states that internal files were taken from the company; no figure for the number of individuals affected has been made public, and the company has not confirmed the claims.
The incident is one of many in which organisations are added to ransomware leak sites after data is allegedly removed during an intrusion. Such listings create uncertainty for any clients, partners or staff whose information may be among the files referenced.
What happened
On April 29, 2022, Semaphore Solutions Inc appeared on the onyx ransomware group’s leak site. The entry indicates that internal files were exfiltrated during a ransomware attack. No additional details on the timing of the intrusion, the volume of data, or the method of access have been disclosed in public reporting.
The group claims to have stolen internal data. Confirmation of the claim, or any statement from Semaphore Solutions Inc about the incident, remains unavailable from the facts provided.
Who is onyx?
Onyx is a ransomware operation that maintains a public leak site where it lists organisations it claims to have compromised. Like other groups of this type, it typically pairs encryption of systems with the removal of data, then uses the threat of publication to press for payment.
The group’s listings are presented by the operators themselves; independent verification of each claim is not always available at the time of posting.
About Semaphore Solutions Inc
Semaphore Solutions Inc operates in the information-technology and software-services sector. Companies of this kind routinely hold internal records that include client project files, employee data, system configurations and correspondence.
A listing on a ransomware leak site therefore raises questions about the security of those records, even when the precise contents remain undisclosed.
What was likely exposed
The only data type named in the listing is internal files exfiltrated during a ransomware attack. No inventory of specific file categories, record counts or data fields has been released.
Organisations in this sector commonly store client information, internal communications and operational documents; whether any of those categories are present in the claimed exfiltration is unconfirmed.
Why it matters
Internal files can contain details that affect clients, employees or business partners even if they are not personal data in the narrowest sense. Publication of such material can lead to follow-on fraud attempts, reputational harm or regulatory scrutiny.
Because the number of people potentially affected is unknown, the practical impact cannot yet be quantified from public information.

Publicly posted by onyx — 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.
