Malware volumes rose in 2007

Wednesday, 16 Jan 2008. Categories: USA

The volume of malware detected grew 16 times in the last quarter of 2007, according to a new study from CA's global security advisors.

The research also found that malicious spyware surpassed Trojans the most common form of malware over the course of the year, accounting for 56 per cent of those detected.

Meanwhile, 32 per cent were Trojans, nine per cent were worms and two per cent were viruses.

The year was further marked by the arrival of more sophisticated spam which is less likely to contain typos and spelling mistakes and is thus more difficult to detect.

Spam is also now more likely to contain attachments, images, PDFs, videos, spreadsheets and documents that contain malware or link to malicious sites, the study said.

Around 90 per cent of all email is spam and more than 80 per cent of this includes a link to malicious sites or malware, tradingmarkets.com reports.
