Several cybersecurity companies are disclosing that they are affected by data theft tied to an earlier breach at market research firm Klue. Reporting from multiple outlets says that at least Huntress, HackerOne, Jamf, Recorded Future, and Tanium have had data stolen, following the Klue incident. SecurityWeek also lists additional organizations that report impact, including OneTrust, Snyk, and Tanium, expanding the set of affected customers beyond the first group. The reports describe the Klue breach as the originating event and frame the subsequent disclosures as results of information accessed or exfiltrated during that incident. While each company’s statement focuses on its own exposure and next steps, all coverage is consistent that data related to multiple cybersecurity firms is involved and that more companies continue to come forward as details are confirmed. The reporting does not provide a full account of the specific data types in the excerpts, but it consistently connects the cybersecurity firms’ disclosures to the same Klue breach.
