Someone Claimed They Breached You. Now What?
Ransomware groups posted 9,469 victim claims to public leak sites between October 2025 and September 2026, according to HackNotice research. A meaningful share of those claims are wrong.
HackNotice Breach Claim Response detects the claim against your domains, disputes it with evidence, changes the public HackNotice breach report, and pursues the sites still repeating it.


The Claim Is Public Before You Can Verify It
A claim appears on a leak site. It spreads to breach databases, security vendors, researchers, and media before anyone verifies it. Left unmanaged, an unverified claim becomes the record.
Why Disputing It Elsewhere Doesn’t Fix It
Threat intel tells you the claim exists. Security ratings score you down for it. Breach aggregators republish it. Some vendors will hear a dispute about their own score or their own entry — but we haven’t found one built to put your correction onto the claim itself, or to chase the copies republished elsewhere.
Add the Domain. We Handle the Rest.
No dashboard to babysit, no report to run. The moment a new claim lands, it’s already matched to the domain, backed by evidence, and sitting in an investigator’s queue.
You hear from us when something changes — a case opens, the record is corrected, or an outlet responds. Not before, and not on a status page you have to remember to check.

A Continuous Intelligence Process
A disputed claim shows a yellow banner while HackNotice investigates. A claim we overturn shows red: claim upheld — this report is false. The public record changes state — not a footnote, not a caveat buried in a PDF. It’s the same report your prospects, insurers, and auditors already pull, now showing the correction next to the original claim.
One workflow, from watch list to corrected record
A documented response process that connects monitoring, evidence, dispute review, and correction.
Add up to five domains or brands. HackNotice backfills breach history and continuously monitors for new claims.
Match incoming breach claims to those domains and organize them in one timeline for review.
Submit the organization’s position and supporting materials for HackNotice review.
When a dispute is upheld, HackNotice updates the public report and tracks best-effort outreach to selected third-party outlets.
A visible correction, not a buried footnote
While HackNotice investigates, the report displays a visible disputed state. When HackNotice upholds the dispute, the public HackNotice report changes state and the incorrect attribution can be withdrawn.
HackNotice can pursue correction or removal with selected third-party outlets and track where the request was sent, whether the outlet replied, and whether the listing remains online.
Third-party publishers remain independent. Outreach is best-effort. HackNotice cannot guarantee that another outlet will correct or remove a listing.

Continuous claim matching, backfilled breach history, HackNotice record review and correction when supported, selected third-party outreach, and outreach status tracking.
Breach Claim Response FAQ
A ransomware group listed our company. Is the claim real?
A listing is a claim, not proof. HackNotice reviews the available evidence and the organization’s supporting materials before determining whether the public record should change.
Can HackNotice remove us from a leak site?
HackNotice does not control ransomware leak sites. The service focuses on correcting HackNotice’s public record and pursuing selected third-party outlets.
What if the claim is false?
Submit the organization’s position and supporting materials. If HackNotice upholds the dispute, the report changes state and the incorrect attribution can be withdrawn.
Can a breach listing be disputed?
Yes. Breach Claim Response provides a defined channel for submitting a position and supporting materials for review.
Who can correct a breach database listing?
Each publisher controls its own records. HackNotice can correct its record when supported and conduct best-effort outreach to selected third parties.
Does this determine whether we must file an 8-K?
No. The service does not provide legal advice or determine regulatory reporting obligations. Organizations should consult their legal counsel.
What if a real breach claim is exaggerated?
The organization can submit evidence addressing the inaccurate elements. HackNotice reviews what the public report should say based on the supported facts.
Can HackNotice correct an overstated record?
Yes, when the evidence supports the correction. The record can be updated to reflect the verified scope rather than the original unsupported claim.
