Advanced Connection Corporation Listed by The Gentlemen Ransomware Group

On February 25, 2026, Advanced Connection Corporation appeared on the leak site of the ransomware group known as thegentlemen. The company, which provides networking technologies and communication services to businesses, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of individuals whose information may have been exposed remains unknown, anyone whose personal or business data passed through Advanced Connection’s systems could be affected.

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 internal files were taken from Advanced Connection Corporation. The incident was listed on the group’s leak site on February 25, 2026. The company operates under the domain acc-plc.com and is described as a provider of communication infrastructure that helps organizations maintain reliable connections across industries. No confirmed count of affected records has been released, and the precise contents of the leaked files have not been detailed in available reporting.

Why This Matters for You and Your Family

When a communications provider is breached, the fallout often reaches ordinary people. Your employer, your child’s school, your doctor’s office, or the utility company you use may rely on services like those offered by Advanced Connection. If your contact details, invoices, contracts, or internal correspondence were stored on their systems, that information can now sit in an attacker’s archive. For families this means heightened risk of identity theft, unexpected spam, phishing emails that look legitimate, and potential harassment if personal phone numbers or addresses surface later.

Credential leaks from incidents like this frequently cascade into account takeovers. A password reused from an old work account can unlock personal email, banking, or social media. Children’s gaming accounts linked to family email addresses are especially vulnerable because young users rarely enable strong security.

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.
