Rhysida Publishes Massive Leak of Berlin Administration Data

Federal and Berlin authorities have started an AI‑assisted forensic review that officials say will take weeks to complete.

Overview

  • The criminal group Rhysida published roughly 1.2–1.44 million files totaling about 5.6–5.8 terabytes in the Darknet after demanding 30 bitcoin and receiving no ransom from the Senat.
  • Authorities report so far that the files include many personal records such as scanned IDs, passports, contracts and passwords, raising acute risks of identity theft and tailored phishing attacks for affected people.
  • Berlin and federal agencies including the BSI, BKA and BfV are jointly downloading the published dataset from low‑bandwidth Darknet servers and using AI to prioritise documents for manual review.
  • Journalists have disclosed internal Senat documents showing officials knew the Landesnetz was not approved to handle even the lowest secrecy tier (VS‑NfD) and a structural fix was scheduled for 2027.
  • The breach has immediate operational effects on city services, political fallout ahead of local elections, and has renewed calls for a nationwide programme to harden municipal IT and standardise secrecy handling.
