Study: Mobile attacks jumped fivefold in 2006

Study finds 83 percent of mobile operators have had subscribers hit by some kind of mobile device infection

The number of security attacks reported by mobile phone operators in 2006 jumped fivefold over the year before, a McAfee study reported Monday.

According to data gleaned from more than 200 mobile operators worldwide, an overwhelming majority -- 83 percent -- said that their subscribers have been hit by some kind of mobile device infection. "This research clearly demonstrates that mobile security is moving quickly up the industry agenda, with the number of malware incidents rising," Victor Kouznetsov, McAfee's senior vice president of mobile security, said in a statement.

Large-scale attacks during 2006 were most likely in Europe, Asia and the Pacific Rim. In those regions, the number of operators reporting incidents that affected more than 1,000 devices doubled during the year.

Operators worry most about the impact of attacks on their reputations and, ultimately, customer satisfaction, the security vendor said. In particular, they worry about the loss of credibility regarding the reliability of new transaction- and content-based services such as music downloads that mobile service providers hope will boost revenue. More than 70 percent of the surveyed mobile operators cited that as a top concern.

"As mobile data use and functionality proliferates, security is becoming an essential enabler for the success of new revenue-generating services," said Kouznetsov.

Predictions of widespread mobile device attacks -- while made annually by security vendors and analysts -- have not yet been borne out. That was backed up by the survey, which noted that attacks involving between 1,000 and 100,000 devices accounted for just 15 percent of all reported security events.

Windows 10 for Business / Dell XPS

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
