A new variant of Zeus Trojan focuses on Software-as-a-service applications for the purpose of obtaining access to proprietary data or code. The SaaS Security firm vendor Adallom, detected a targeted malware attack campaign against a Salesforce.com customer, which began as an attack on an employee’s home computer. The Security firm noticed the attack when they saw about about 2GB of data been downloaded to the victim’s computer in less than 10 minutes. While Zeus usually hijacks the user session and performs wire transactions, this variant crawled the site and created a real time copy of the user’s. account that contained all the information from the company account.
