Exploits Block List - Two Botnets Contribute to 50% Increase in Listings

The report describes a significant rise in Spamhaus XBL listings (approximately 10 million to 15 million), attributing roughly half the increase to a new spambot distributing Chinese pornography spam—possibly exploiting proxy software vulnerabilities in China—and the remainder to continuing infections linked to the Avalanche/Gamarue botnet; infected hosts remain active and continue to spread infections despite previous takedowns, and the actor behind the new spambot is not yet identified.
