DIALLOG Listed by Nova Ransomware Group

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

Diallog was listed on Nova's leak site. Nova claims to have stolen internal data. This is the group's claim, not a confirmed finding.

On April 27, 2025, Canadian telecom provider Diallog appeared on the leak site of the nova Ransomware Group, with the attackers claiming to have exfiltrated internal files following a ransomware incident.

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.

Reported Details from Reports

Public reporting indicates that Diallog Telecommunications, a Toronto-based company founded in 1998 and operating as a Canadian-owned provider, had internal files taken. The nova Ransomware Group listed the victim on its dark-web leak page on April 27, 2025. Available reporting describes the exposed material as internal files, though the precise volume and full list of data types remain unclear. No confirmed customer count or specific personal data categories such as names, addresses, phone numbers, or payment details have been publicly detailed by the company or the group.

Why This Matters for You and Your Family

If you or any member of your family uses Diallog for home phone, internet, or mobile service, your contact details and account records may sit inside the stolen files. Even when exact victim numbers are unknown, telecom breaches routinely expose billing addresses, phone numbers, email accounts, and sometimes device identifiers. Once that information leaves the company’s control, it can be sold quietly on underground forums and used to target you with phishing texts, spoofed calls, or identity-theft attempts. For families, a single exposed landline or mobile number often links parents and children, multiplying the ways attackers can reach every household member.

The Doxxing and Identity-Chain Risks

Telecom records are especially dangerous because they bridge online handles to real-world identity. A phone number allegedly leaked from Diallog can be cross-referenced with gaming accounts, social-media profiles, and email addresses to build a complete picture of you and your children. Credential leaks of this kind frequently cascade into account takeovers on Steam, Roblox, Discord, or other platforms where kids use the same email or password. Public reporting shows these chains allow doxxers to publish home addresses, family names, and live locations within hours of the initial breach.

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.
