LeakedData is tracked by this dashboard as a data-extortion operation that publishes victim listings on a public leak site: 38 victims have been listed since tracking began on 2026-08-08, including 4 in the past 7 days and 25 in the past 30 days, with the most recent post on 2026-09-03. The victims publicly identified to date are prominent US law firms, indicating a focus on the legal and professional services sector. Whether the group deploys ransomware alongside extortion, or operates as an extortion-only brand, is not established in widely available public reporting. Attribution, country of origin, affiliate structure, and demand amounts are unknown, and no public earnings estimates have been published. Defenders in legal and professional services should treat LeakedData as an active extortion threat and monitor for victim disclosures.
