3-Second Blueprint (English)

  1. Attackers infected 333 Tor exit relays (~10% of exits) with the Ebury OpenSSH backdoor to intercept port 22 traffic.
  2. Redirected SSH sessions triggered host-key warnings; users logging in with passwords had credentials stolen and hosts infected.
  3. A developer used exitmap to probe SSH fingerprints across every Tor exit relay, exposing the campaign; SSH keys prevent theft.

3-Sekunden-Fazit (Deutsch)

  1. Angreifer infizierten 333 Tor-Exit-Nodes (~10 %) mit der OpenSSH-Backdoor Ebury, um Port-22-Verbindungen umzuleiten.
  2. Ignorierte Host-Key-Warnungen bei Passwort-Logins führten zu Passwortdiebstahl, Befehlsüberwachung und Serverinfektion.
  3. Per exitmap-Skript wurden fehlerhafte SSH-Fingerprints aller Exit-Relays enttarnt; SSH-Schlüssel verhindern den Angriff.
