Unverified claim
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, via the ransomwarelive mirror, posted a claim naming Longhorn Investments, a financial services entity, as a victim. The posting alleges the group has listed this organisation on its leak site. This is the sole fact: a claim was published.
Longhorn Investments has not confirmed this claim. Leak-site postings are frequently exaggerated, false, or misattributed, and may reference a third party rather than the named organisation. Compliance teams should treat this as unverified, request a written statement directly from Longhorn Investments, and refrain from acting on it as a confirmed incident.
