centrum.sk Listed by APT73 Ransomware Group

On April 27, 2026, Slovakian online portal centrum.sk appeared on the leak site of the ransomware group apt73. The company, which provides email services, news, and other digital content to users across Slovakia, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people affected remains unknown, anyone with an account on the platform or whose information passed through its systems could have personal data now at risk.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that apt73 posted details of the centrum.sk breach on its leak site, accessible via an onion address tracked by ransomware.live. The data consists of internal files exfiltrated after the ransomware group gained access to the company’s systems. No specific deadline for ransom payment has been publicly detailed in available reporting, but the listing itself signals that negotiations either failed or were never pursued. The breach involves an email provider used by ordinary people for everyday communication, meaning everyday documents, contact lists, and account details may have been taken.

Why This Matters for You and Your Family

When an email provider like centrum.sk is hit, the consequences reach far beyond the company. If you or anyone in your family maintained an email address there, those credentials could surface in follow-on sales or dumps. Criminals routinely test leaked email-password pairs across banking, shopping, and government sites. For families, this risk multiplies when children share devices or reuse simplified passwords. A single breach can quietly expose your household for months before you notice unusual activity on accounts you thought were safe.

The Doxxing and Identity-Chain Implications

Leaked internal files frequently create doxxing chains. An email address from centrum.sk can be linked to usernames on forums, gaming platforms, or social media. Once attackers map one handle to a real name or address, they can uncover additional accounts belonging to you or your children. Credential leaks like this one cascade into account takeovers, especially for gaming accounts that often use the same email. Public reporting describes these identity chains as the bridge between an initial breach and full identity theft, harassment, or financial fraud. What begins as “just an old email portal” can become the starting point for someone targeting your family’s privacy.

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.
