In my previous post I talked about the discovery of targeted malware embedded in physical scanners that were sold to shipping and logistics companies. Once operational the malware searched the victim’s network for ERP systems, compromised them (from the report it would appear all systems were compromised; and based on our own experience that has been the case in our engagements) and coped the data from these systems back to command and control servers, reportedly based in China.
It is tempting to think that this is an isolated problem only specific to one industry, but the reality is all businesses have hardware attached to their network that runs or has access to their critical systems and infrastructure. Counterfeit equipment is a long standing problem, with these fakes being hard to detect from the real thing. With the practice of the hardware being assembled by one company and the firmware being produced by another there is even more room for malicious software or instructions being added to printers, switches, routers and other equipment that exists in almost every network today.
