Microsoft Corp. today released research showing an acceleration in the number of security attacks designed to steal personal information or trick people into providing it through social engineering.

Microsoft�s most recent Security Intelligence Report, a comprehensive analysis of the threat landscape, shows that attackers are increasingly targeting personal information to make a profit and are threatening to impact people�s privacy. The report found that during the first half of 2007, 31.6 million phishing scams were detected, an increase of more than 150 percent over the previous six months. The study also shows a 500 percent increase in trojan downloaders and droppers, malicious code used to install files such as trojans, password stealers, keyboard loggers and other malware on users� systems. Two notable families of trojans detected and removed by the Microsoft Malicious Software Removal Tool are specifically targeted at stealing data and banking information.

Microsoft also released findings from a recent survey of more than 3,600 security, privacy and marketing executives across a variety of industries in the United States, the United Kingdom and Germany, including financial services, healthcare, technology and government. Conducted by the Ponemon Institute LLC, the study found that as security threats increasingly target personal information, more collaboration among security and privacy officers is critical to avoid costly compromises or breaches of personal information.
