MessageLabs Intelligence came up with the 2008 cybercrime list

MessageLabs Intelligence announced that the average spam level for the year managed to hit 81.2 percent. However, it was not as shocking as the given results of malware levels. It only managed to average out at 0.7 percent or just 1 in 143.8 messages. MessageLabs also presented Top Cybercrimes of 2008 list that covers the most notable of these malware attacks. Among the naughty listed are the Storm worm. It was noted as rather aggressive and leading to the formation of one of the biggest botnets ever seen. Among others on cybercrime list are CAPTCHA systems.  

According to MessageLabs CAPTCHA breaking techniques continued to increase in sophistication and became the key to the spamming kingdom. 

A number of new versions of Trojans were observed in 2008. They managed to evade anti-virus systems courtesy of code variations. In general, Web-based malware has continued. And the number of new and malicious sites being blocked increasing by more than 90 percent in July. 
In May the spammers discovered the perfect way to spam: links to hosted online documents created under accounts with a major hosted applications service provider, which simply were not blocked by traditional spam filters. The Srizbi effect also influenced present online fraud situation. It infected 1.3 million computers and caused at least 50 percent of all spam in 2008.

One of the latter invented spams being on the cybercrime list was based on politic environment. It is so called "Obama spam". Online fraudsters used the Barack Obama name to lure recipients' attention. The first spam of such sort appeared with watches or pills selling but spoofed email addressed from the following domains: barackobamaismyhomeboy.com and barackobamaisyournewbicycle.com. So popular website intended to honor the presidential candidate's altruism turned to be a potential danger of cyber crime attacks. The second run of Obama-related spam foreshadowed the outcome of the election using Obama subject lines 85 percent of the time.
