New Moves for Spammers in '07

Prediction: Spammers must find new attack techniques in 2007.
One of the most unlikely predictions for 2007 comes from SecureWorks malware researcher Joe Stewart: spammers will have to evolve and find new attack techniques if they intend to maintain their level of profitability. Roughly translated, Stewart believes the massive surge in spam e_mail will taper off in 2007, unless spammers find new tricks to bypass a hardened
Windows Vista and improvements to existing anti_spam technology and techniques. In an entry on the SecureWorks blog, Stewart argued that Vista will force spammers to deliver payloads through social engineering attacks and even that might become more difficult in the future, with Microsoft venturing into the anti_virus and trusted computing arenas. "Another
factor which will have a huge impact is the release of the SpamHaus PBL blocklist, scheduled for release in December 2006," Stewart added. Stewart explained that spammers depend on these dial_up and DHCP_based broadband connections and, with the extensive reach of SpamHaus' blocklists, widespread adoption of the PBL, or Policy Block List, "will be very detrimental to spammers, as entire IP blocks where their zombie spam bots live will be unable to send mail to a large part of the Internet."
