ANTEL Listed by kelvinsecurity Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The ANTEL Listed by kelvinsecurity Ransomware Group (reported April 1, 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.
What happened
Public records show that ANTEL was added to the kelvinsecurity ransomware leak site on April 1, 2022. The entry stated that internal files had been exfiltrated. No further details on the timing of the underlying intrusion, the volume of data involved, or the method of access have been disclosed in connection with this listing.
The group claims to have stolen internal data from the organization. Confirmation of the claim, including whether any data was subsequently published or used, has not been made public.
Who is kelvinsecurity?
Kelvinsecurity is a ransomware operator that conducts encryption attacks against targeted organizations and maintains a leak site to list victims. The group follows a pattern seen with several ransomware actors: after gaining access, it exfiltrates files and then posts notices demanding payment to prevent further disclosure.
Public reporting on the group documents repeated use of this approach across multiple sectors. Its listings function as claims of possession rather than independently verified releases of data.
About ANTEL
ANTEL is an organization that maintains internal operational records and communications systems. Entities of this type routinely store administrative documents, network configurations, and employee-related files as part of day-to-day operations.
A listing on a ransomware leak site draws attention to the handling of such internal material, regardless of whether the data later appears in public.
What was likely exposed
The only data type referenced in the listing is internal files exfiltrated during a ransomware attack. No inventory of specific documents, file counts, or categories has been released.
Organizations in this sector commonly retain records that include business correspondence, technical infrastructure details, and personnel information. The exact scope of material taken in this case remains unconfirmed beyond the general description provided by the group.
Why it matters
Exposure of internal files can reveal operational practices or sensitive administrative details that affect an organization’s ability to function securely. Where personal information is present in those files, individuals may face secondary risks such as targeted phishing or misuse of credentials.
Because the number of records and their contents are not publicly specified, the scale of any downstream impact cannot be quantified from available information.
If your data was in this claimed breach
Individuals can review account statements and login activity for any services linked to ANTEL. Changing passwords for affected accounts and enabling multi-factor authentication where available are standard initial steps.

Publicly posted by kelvinsecurity — 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.
