MALWARE HAS INCREASED by 26 per cent in the first quarter of 2011, according to a report by insecurity research firm Pandalabs.
The worrying increase means that over 73,000 samples of new malware are being detected on a daily basis so far in 2011, an extra 10,000 per day compared to 2010.
Most of the malware are Trojans, accounting for 70 per cent of all threats. Viruses are at just under 17 per cent, while worms are at just under eight per cent. Adware, spyware and backdoor malware took a much smaller chunk of the pie, but still present a valid threat.
Within the Trojan subheading, many types have decreased in popularity, such as banker Trojans and rogueware. Bots have remained at their prior level, while downloaders, which as the name implies download additional malware, have grown substantially, up from a share of nearly 20 per cent in January to a whopping 47.8 per cent in March.
Pandalabs attributes the substantial growth of Trojans to the distribution of online tools that allow anyone to create a Trojan in minutes. Couple that with the lure of being able to make easy money through illegal activity and it's not surprising that we're seeing such high growth in malware. µ
