What happened
In May 2026, the real estate services firm Cushman & Wakefield was the target of a "pay or leak" extortion campaign by the ShinyHunters group. Following the threat, the group publicly published data they alleged had been obtained from the firm, consisting mostly of C&W email addresses along with tens of thousands of external email addresses and corporate contact records. The exposed data was primarily business information, including names, job titles, company addresses and phone numbers.
