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

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, a researcher reported Tuesday. The hijacking began in late August, when according to Tor volunteers , the attacker used a valid password that had been reused to gain access to a Tor management server. The attacker then installed Ebury , a backdoor written for Linux that was discovered 12 years ago.
