Malware risk is growing exponentially

A company in ScanSafe's focus group faced a nearly 500 percent greater risk of exposure to those threats in September than was faced in January of this year, according to ScanSafe's Global Threat Report released on Tuesday.

Companies in the energy sector are at greater risk from Web-based malware than other industries, the report concludes. The energy sector, worldwide, faces a 189 percent higher risk of exposure from workers visiting sites with malware on them than other industries, followed by the pharmaceutical and chemicals industry, construction and engineering, and media and publishing.

"On a more positive note, government agencies were at 0 percent, which indicates they were at neither higher nor lower rates of exposure compared to other verticals," Mary Landesman, senior security researcher at ScanSafe, writes in a blog post.

The industry with the lowest rate of exposure was aviation and automotive. Landesman says she can't say exactly why one sector is more at risk than another but expects to release more findings soon that could help answer that question.
