Symantec's latest security report. (Michael Crawford, 22/03/2005)
Firefox has gained a lot of attention as a secure web browser, however, new statistics show it is only marginally more secure than Internet Explorer, with half of Firefox's vulnerabilities reported as critical. This is the finding of Symantec's Internet Security Threat Report released today, which found that of the 21 vulnerabilities recorded in Firefox, eleven were found to be severe. Nine of the 13 vulnerabilities recorded in Internet Explorer between 1 July and 31 December 2004 were either critical or highly severe.
Symantec added that patching, changing passwords and not "opening attachments for the sake of it" would significantly reduce the element of risk and potential harm. The Internet Security Threat Report also found a steady rise in the number of Win32 viruses and worm variants, finding 7360 new viruses and worms in the latter part of 2004 - an increase of 65 percent compared to the previous six months. The number of attacks per day on individual organizations went up from an average of 10.6 to an average of 13.6 attacks per day. Symantec said they now see multiple variants of the one virus family, which they put down to as a malicious-code attacks between various groups as a way to tweak the code to bypass antivirus engines. The intention is still there to open ports and create spybots or whatever, but writing viruses to crash systems just for the sake of it is now less of a desirable outcome. It is now about controlling a system unbeknown to the user and using that system as a feed to get personal information!
The report noted that of all the security threats from malicious code, 54 per cent were "created to expose confidential information," up from 44 per cent in the first six months of the year and 36 per cent in the second half of 2003. Many of these viruses, known as Trojan horses, install a program that allows hackers to remotely access a computer and find passwords or monitor keystrokes. Trojans represented 33 per cent of the top 50 threats reported to Symantec. Symantec found 17,500 different types of viruses and worms as of December 31. Email remained the most prevalent threat from viruses but Symantec cited increased attacks on servers and web applications. Attacks hidden in embedded content in audio and video images are expected to increase. This is worrisome because image files are ubiquitous, almost universally trusted, and an integral part of modern-day computing. Other growing threats include spyware, which enables third parties to track computer activities, and spam, or unsolicited email, which can contain other threats. Spam increased from an average of 800 million messages per week to well over 1.2 billion spam messages per week by the end of the reporting period, making up more than 60 per cent of all email traffic observed by Symantec during this period.
