Korean spammer alleged to have sent 18 million spams per day
Experts at SophosLabs™, Sophos's global network of virus, spyware and spam analysis center, have welcomed the news that the South Korean authorities have arrested a man suspected of running a 16,000-strong network of zombie computers.
According to the state-backed Korea Information Security Agency (KISA), the man is believed to have sent 18 million spam emails to 133 countries every day from his network (or botnet) of compromised computers.
Working with the police, KISA identified a man who has been running the botnet of 16,000 computers for the last six months using it to send out large amounts of loan-related spam.
Last month, Sophos published a report placing South Korea as the third biggest relayer of spam, accounting for almost 10% of all junk mail seen by Sophos's global network of spam traps.
