According to the Trend Micro World Wide Tracking Centre, Sasser was the most prevalent virus in August with 325,409 victims and made up nearly 31 percent of infections in the August top 10 virus list.

Mark Sinclair, Trend Australia’s technical services manager, said both viruses were written by the same programmer; an 18-year old German who was responsible for 77 percent of infections by the top ten viruses in August. “According to Trend Micro statistics, the NetSky series has been listed among the top ten viruses since February, accounting for over half of the top ten viruses between April and July.

Most of the new viruses were variations of previous viruses, with eight new variants of the Worm _rbot series, and nine variants of the Worm_sdbot series. Another possible motive is to build a dormant “dark” network that could be used in the future to perform a large-scale attack against one or more targets.

“Mass mailers usually feature executable file attachments and stripping these attachments at the gateway is a simple method of reducing infection,” Sinclair said. “The authors of Bagle continue to wage war on Netsky; proof of concept viruses are appearing for wireless devices and 64 bit operating systems and phishing/keyboard logging Trojans are becoming more prevalent,” he said. “The potential to see new damaging network worms such as Sasser, SQL Slammer and Blaster is always there.

The top five targets of Internet bank fraud in August were US Bank, Citibank, Suntrust Bank, eBay and Paypal.

By passing the buck wholesale to the IT department companies are exposing a number of flaws across their organisation – from the top down – and even a tightening of legislation and increased emphasis on accountability and corporate governance has done little to interest the head-in-the-sand ‘higher ups’ that they should be getting involved and delegating tasks effectively.

According to independent research conducted by Coleman Parkes on behalf of LogicaCMG, 53 per cent of companies entrust the IT department with the sole enforcement of the information security policy. In addition, 71 per cent of companies rely on the IT department to implement information security policies and approaches – despite the fact that much of the planning should relate to HR and legal issues as much as to the technology in place.

Sal Viveros, SME director at security giant McAfee, believes one of the biggest obstacles to effectively managing security issues centrally from the IT department is the perception of other employees. Viveros said as a result those in the IT department are often seen as “the bad guys” and coupled with a perceived lack of seniority within the company this makes it difficult for them to dictate, manage and enforce policy.

While staff may sit up and take notice of a policy handed down by HR or a member of senior management, because the trail of accountability and its direct link to discipline procedures is evident, employees may feel less inclined to treat seriously the requests of the IT department.

In a separate study conducted by MORI, also on behalf of LogicaCMG, 83 per cent of investors said a security breach of any kind would impact that companies’ share price and 56 per cent they would sell their shares in the event of a breach.

The fact companies are seemingly doing little about getting on top of security is made all the more surprising by the fact companies are aware of such risks.
