A new variant of the Citadel financial malware uses in-browser injection techniques combined with extensive content localization to steal log-in credentials and credit card information. The new Citadel variant targets users of social networks, banks and major e-commerce sites, researchers say. Microsoft said earlier this month that it worked with the FBI and other technology industry partners to disrupt more than 1,400 botnets based on the Citadel malware. Microsoft estimated at the time that those botnets were responsible for more than US$500,000 million in losses.”]
