If you are a customer of MS Security & Personnel, here’s what is being claimed, and what it would mean for you.

MS Security & Personnel was listed on Kairos's leak site. Kairos claims to have stolen internal data. This is the group's claim, not a confirmed finding.

What Public Reporting Shows

Public reporting indicates the data was exfiltrated during a ransomware attack. The listing appeared on the group’s onion site, hosted via ransomware.live, and includes what the attackers describe as sensitive internal documents. The exact number of people whose personal information is contained in the 1.48TB remains unknown. No evidence has surfaced that the files have been broadly distributed beyond the leak site at this stage.

1.48TB of internal files were posted, the incident was publicly listed on October 10, 2025, and the victim is a security and personnel firm operating in Cyprus. These details are drawn from the group’s own leak page and independent ransomware trackers.

Why This Matters for You and Your Family

When a company that handles personnel records and security contracts is breached, the information inside often includes names, addresses, dates of birth, national identification numbers, employment histories, and contact details of ordinary people. If you or anyone in your household has ever worked with a security contractor, applied for a job through one, or had background checks performed, your data could be among the records now in attackers’ hands.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
