An analysis of hacker attacks on online servers in January by security consultancy mi2g found that Linux servers were the most frequently violated, accounting for 13,654 successful attacks, or 80% of the survey total. Windows ran a distant second with 2,005 attacks. A more specific analysis of government servers also found Linux more susceptible, accounting for 57% of all breaches. The research did not include other methods of intrusion such as viruses and worms.
