The number of new file-sharing sites hosting unauthorised, copyrighted content skyrocketed over the last three months, according to McAfee's Third Quarter Threats Report. The report also shows that spam, malware and Web-based threat creation has reached record levels in the last quarter and that cybercriminals are extorting site-owners with threats of DDoS attacks.

Cybercriminals are taking advantage of a 300% jump in the creation of file-sharing sites that occurred while a famous torrent site – a site which can host links to copyrighted content – The Pirate Bay, was prosecuted in Sweden. As users develop more sites to share content, malware writers are creating sites to trick users looking to download copyrighted material into downloading malicious programs. McAfee predicts the number of these malicious sites will increase during the next month or two and holiday blockbuster film seasons.
Many of these sites sprang up to scam users of The Pirate Bay who were looking for a new place to download copyrighted material. McAfee researchers observed that users began creating their own sites to support The Pirate Bay community when the site was in the process of being shut down. When the site was back up after only 24 hours, the new torrent sites disappeared quickly.
McAfee Labs' analysis revealed peaks in the creation of these sites which correlate to major events in the film industry. During the release of the upcoming blockbusters, McAfee observed a peak, as well as during this year's Oscar Season and 2008's holiday movie season. McAfee expects a similar peak during this year's release of "Oscar-bait" films and the holiday season.
The McAfee report also found that spam and malware levels have reached an all-time high, with threats surpassing previous records in the last quarter. Web-based attacks have also increased as cybercriminals take advantage of celebrity deaths and natural disasters.
Spam reached its highest level in history, breaking the previous record set in the second quarter of 2009 by 10%, now comprising 92% of all e-mail. When compared with the third quarter of 2008, spam jumped 24%.
Web-based attacks are the newest hot threat vector and have become one of the most dangerous tools cybercriminals utilise. These attacks can target anyone who visits a malicious Web page and are delivered to users through spam, phishing, social networks and even through redirects from hijacked legitimate Web sites. Fifty-five percent of all malicious URLs are hosted in the US, and cybercriminals are getting increasingly effective at utilising SEO techniques to drive traffic to these bad sites. Malware authors take advantage of news stories like the death of celebrities and natural disasters to hide their malicious intentions.
In the last quarter, McAfee Labs observed many new denial-of-service attacks, including some that demand ransom. Four Australian sports betting companies were taken down during key events like the football and rugby finals, resulting in millions of dollars of losses.
DDoS as a service is growing in popularity, with many cybercriminals offering botnets comprised of thousands of zombie computers to attack sites for the highest bidder. These botnets are capable of knocking even some of the most-protected sites offline. Cybercriminals will even offer a "demo" performance for a few minutes to prospective buyers.
