Below is a summary of RSA Security’s June 2011 Fraud Report.

RSA recently analyzed one local pharming Trojan which they found to be a highly sophisticated piece of malware that goes as far as installing a driver to achieve its intended goal of stealing information. This is the first local pharming Trojan observed by RSA to even have a driver.

In fact, the Trojan has been widely reported to be the first rootkit ever designed to specifically infect 64-bit operating systems. However, the Trojan does not in fact install a rootkit; rather it installs a plainly visible malicious driver. Since rootkits by definition hide their very existence from the user, this driver cannot be classified as such. Any victim infected with this Trojan, dubbed Rootkit.Win32.Banker.dy (on 32-bit systems) or Rootkit. Win64.Banker.a (on 64-bit systems) will be able to see it in plain view on the currently-loaded driver list.

This particular Trojan was targeted at online banking consumers in Brazilas it changes the hosts file settings for a handful of Brazilian Banks.

Phishing Attacks per Month

May 2011 marked a surprising 33 percent increase in the number of global phishing attacks identified by RSA – and a record for the most unique attacks identified in a single month. About four out of five phishing attacks in May were launched using hijacked websites.

Number of Brands Attacked

The increase in phishing attacks numbers was not the only substantial change observed in May. RSA witnessed a 25 percent increase in the number of attacked brands suggesting criminals went after a wider variety of brands rather than consistently attacking the same brands. When compared year-over-year (May 2010), there was a 69 percent increase in the number of attacked brands.

Segmentation of Financial Institutions Attacked Within the U.S.
