Trojans Dominate Online Threat Landscape in Q2-2010

Computer trojans held a share of around 52% in the new malware created during the past three months (April-June 2010), reveals Panda Security's new quarterly report on IT threats (Q2-2010).

According to the report, trojans continue to be the most preferred malware types by the cybercriminals. It's not at all surprising given that threats like Clampi and Zbot, which stole millions of dollars from users and enterprises in just last one year, belong to this category only. Majority of spam today originate from Trojan-infected PCs.

Apart from this, the report claims that traditional PC viruses have continued to revive since the beginning of 2010, accounting for around 25% of all malware in comparison of 15% in Q1-2010. This surge is largely due to a small number of hybrid viruses replicating themselves at very high rates, making the lines between traditional viruses and other types of malware more and more blurred.

Expressing his views in this regard, Sean-Paul Correll, PandaLabs' Threat Researcher, said that modern day threats combine capabilities of traditional viruses with trojans and worm-like characters, reported prnewswire.com on July 1, 2010. He also added that the Internet threat landscape is now shifting from the 'Trojan and Virus' world to the all-inclusive term of 'malware'.

As per the report, in terms of regional distribution, Taiwan was the most severely affected country, with the presence of atleast one infection on over half of the systems scanned. Russia follows closely with just under 50%, while Turkey round offs the top 3 with around 45%. Another striking feature noted in the report is that the all of the first 15 nations on the list recorded over 30% infection rate, indicating that one out of three computers was infected.

Other threats highlighted in the report are the BlackHat SEO and constant attacks on social networking sites, including the recently discovered Clickjacking scam on Facebook that exploited the "like" button.

Finally, as far as phishing is concerned, the report discusses the new and potentially harmful phishing technique dubbed 'Tabnabbing' that emerged in May 2010. This technique used a JavaScript command to detect when a previously opened page is not being viewed by the users, and rewrites that page's content as well as title and icon automatically, imitating the appearance of the legitimate page.
