The Anti-Phishing Working Group (APWG) recently issued its Phishing Activity Trends Report for H1-2011 i.e. first ½-year of 2011 according to which, certain crimeware's propagation rose during January-June 2011, with malicious programs, designed to steal data climbing to a new infection level as well as remaining stable thereof, so published Marketwatch.com in news on December 25, 2011.
Specifically, during H1-2011, there was an over 45% rise in data-stealing programs as well as general PC Trojans from total malware spotted between January 2011 and April 2011.

Previously, the maximum increase in these malware programs was 44% during just one month i.e. August 2010.
