333 Tor exit nodes hijacked to intercept SSH traffic and retrieve plaintext email

Summary

Hackers hijacked 333 Tor exit nodes to intercept SSH traffic and unencrypted email. The attack, which lasted three days, involved the Ebury backdoor and aimed to steal sensitive data. Investigations are ongoing to determine the full extent of the compromise and attacker motives.

Key Takeaways

1. Unknown hackers hijacked more than 300 Tor exit nodes and reconfigured them to favor unencrypted email traffic and redirect SSH connections through servers they controlled.
2. Ultimately, 333 exit relays were involved in the SSH and email interception campaign, although investigators haven’t established how the attackers gained control of all the underlying servers.
3. The takeaway from the event is the crucial role in-depth defense plays in preventing data theft in mass hacks like this one.
