When a ransomware group names your company on a public leak site, the damage can spread faster than the truth. HackNotice’s new service is built to give organizations a documented path to fight back.
HackNotice has rolled out Breach Claim Response worldwide, offering companies a structured process to identify, challenge, and fix breach claims tied to their domains that are wrong, incomplete, or misleading.
The urgency is clear from the numbers: between October 2025 and September 2026, ransomware gangs posted 9,469 victim claims to public leak sites, according to HackNotice research. In the time it takes a company to figure out what actually happened, that claim can ripple outward—showing up in breach databases, risk scoring tools, research reports, customer communications, and press coverage.
Breach Claim Response replaces that chaotic scramble with a repeatable workflow. A company adds the domains and brands it controls to a watchlist. HackNotice then matches incoming breach claims against those assets and organizes them into a single timeline. If a claim is inaccurate, misattributed, exaggerated, recycled from an old incident, or missing key context, the organization can submit its side of the story along with supporting evidence for HackNotice to review.
The service is built around four stages:
1. Watch. Keep tabs on up to five owned domains or brands and pull in their available breach history.
2. Detect. See all matching claims in one timeline, including the event date, source, severity, and dispute status.
3. Dispute. File the organization’s position and supporting materials through a structured case, with direct communication to the HackNotice reviewer.
4. Correct. If the dispute is upheld, the public HackNotice record is updated to reflect the verified facts, and HackNotice makes best-effort outreach to selected third-party outlets that are still repeating the claim.
Disputes aren’t limited to outright denials. A company might acknowledge an incident occurred but push back on the attribution, scope, timing, affected systems, number of records, types of data, or whether the data came from a vendor. The goal is straightforward: make the public record match what the evidence actually supports.
“Breach intelligence should not stop at detection,” said Steve Thomas, CEO of HackNotice. “Organizations also need a clear path to investigate a claim, state their position, correct the record when the evidence supports it, and document what happened from the first alert through third-party outreach.”
There’s a limit to what any service can guarantee here. HackNotice controls its own breach reports, so those can be visibly flagged as disputed during review and corrected if the dispute holds up. But independent publishers run their own sites. HackNotice can identify relevant outlets, send correction requests authorized by the customer, track responses, and log outcomes—yet it can’t force another site to change, remove, or even acknowledge a listing.
Breach Claim Response is available globally at $5,000 per year. That fee covers monitoring for up to five domains and response handling for up to two incidents annually.

Why it matters: With thousands of ransomware victim claims posted publicly each year, a single false or exaggerated listing can damage a company’s reputation and customer trust long before the facts are sorted out. A structured dispute process gives organizations a way to reclaim control of their narrative—and puts pressure on the broader ecosystem to treat breach claims with more scrutiny.
