Unverified leak-site claim: Coinbasecartel names Integrated Health Systems (US) — Healthcare

This is not a confirmed breach. This entry records that a ransomware group posted a claim on its own leak site. Matproof has not verified the claim and does not assert that any incident occurred. Such claims are often exaggerated, false, misattributed, or refer to a third party rather than the named organisation. The named organisation has not confirmed it.

If you represent a named organisation and this entry is inaccurate, email legal@matproof.com and we will correct or remove it.

On 2026-08-22, the ransomware group Coinbasecartel published a claim on its leak site, mirrored by ransomwarelive, naming Integrated Health Systems (US) in the healthcare sector. The posting alleges an incident involving the organisation, but no breach, data theft, or system access is established. The named organisation has not confirmed the claim, and leak-site postings are frequently exaggerated, false, or misattributed; the claim may also refer to a third party.

Compliance teams should treat this as unverified. Contact Integrated Health Systems directly and request a written statement addressing the claim. Do not treat this as a confirmed incident, escalate internally as a breach, or notify regulators based solely on the posting. Await official confirmation before taking any further action.
