Roundup: Tor exit hijacks, Heartbreaker ransomware, and platform breaches
A researcher says 333 Tor exits, about a tenth of them, captured SSH passwords and tried to plant Ebury.
A researcher says 333 Tor exits, about a tenth of them, captured SSH passwords and tried to plant Ebury.
Attackers reused a password, installed the Ebury backdoor, and sent port-22 SSH to 12 servers from October 2 to 5.
About one in ten cited exit relays redirected port 22 to 12 interception servers from October 2 until BadExit flags and shutdowns on October 5.
Only password SSH logins over Tor from October 1 to 5 that accepted a fake host key could be captured.
The relays were about 10% of Tor’s exit capacity; Tor flagged them BadExit by October 4 and infected servers were shut down October 5.
More than 330 relays were infected from October 2 to 5 to sniff SSH and downgrade email before Tor blocklisted them.
About 10% of Tor exits ran Ebury 1.8.3; relays were BadExit-flagged by October 4 and later shut down.
