These first three months have witnessed some particularly intense virus activity and there have been a number of serious incidents during this period, such as: the largest single attack against Android cell phones, intensive use of Facebook to distribute malware, and an attack by the Anonymous hacktivist group against the HBGary Federal security firm.

There has been a new surge in the number of IT threats in circulation: in the first three months of the year, there was a daily average of 73,000 new samples of malware, the majority of which were Trojans. This means that hackers have created 26 percent more new threats in the first months of 2011 than in the corresponding period of the previous year.

Once again, over this quarter Trojans have accounted for most new threats, some 70 percent of all new malware created. Yet there is a logic to this, as these types of threats are favored by organized criminals for stealing bank details with which to perpetrate fraud or steal directly from victims’ accounts.
