2026 — Cushman & Wakefield - alleged ShinyHunters Salesforce theft affecting 500k+ records
Unverified claim — treat actor counts cautiously. Ransom-monitoring coverage and an X post by TweetThreatNews reported that ShinyHunters claimed responsibility for an incident affecting Cushman & Wakefield. The claim alleged more than 500,000 Salesforce records containing PII and internal corporate data, with a final warning deadline of May 6, 2026. Hendry Adrian explicitly marked the post as based on public ransomware-group claims and not independently confirmed, so this record is treated as alleged pending official confirmation. Exposed categories include Alleged Salesforce records containing PII and internal corporate data. BreachHistory cites approximately 500K+ affected records in this row. See the cushman-wakefield2026-shinyhunters and canonical BreachHistory entry.
