2026 Weil Gotshal — Luna Moth extortion; limited client documents uploaded externally
Data compromised
Limited number of client documents per Weil notice; impacted clients contacted individually
Technical writeup
Weil, Gotshal & Manges LLP confirmed in a June 2026 statement that it responded to a cyber incident in which a threat actor uploaded a limited number of client documents to an external cloud storage site, activated incident response with third-party forensics, and notified law enforcement. The firm said the attacker did not access Weil’s network, operations were not disrupted, and affected clients were contacted directly. The Insurer reported Weil paid roughly $18–20 million to Luna Moth to suppress publication—a payment Weil did not confirm—while Legal Cheek published the company’s attested scope as limited external document exposure rather than a full firm network compromise. No public victim count was issued; BreachHistory uses recordsAffected 0 pending client-specific notices.
