With critical business services migrating to the cloud, service providers have become a prime target for cybercriminals. In the latest example of financial malware targeting enterprises, Trusteer has discovered a Zeus attack that focuses on cloud payroll service providers. These attacks are designed to route funds to criminals, and bypass industrial strength security controls maintained by larger businesses.
Trusteer researchers have captured a Zeus configuration that targets Ceridian, a Canadian human resources and payroll solutions provider. In this attack, Zeus captures a screenshot of a Ceridian payroll services web page (https://clients.powerpay.ca/powerpay/Logon*) when a corporate user whose machine is infected aeuk eaf Gxkcho xnhaqu rsji nslocis.
