It is not a surprise to read that the Department of Homeland Security believes that there are foreign made counterfeit components that have been intentionally tampered with in an effort to allow future cyber attacks. (See this article from ABC News: U.S. Suspects Contaminated Foreign-Made Components Threaten Cyber ....) If these components are used in sensitive electronic systems, those systems would be left open for a cyber warfare attack.
There are several key counterfeit examination tests that can be performed to identify these counterfeit components. To attack this issue immediately one needs to capture all the manufacturer part types and their date codes and perform a sample test evaluation in accordance with Military Standard 105D to uncover any anomalies in accordance with those date codes. For example, if 35,000 products of an LM333 component with a date code of 9912 were manufactured in 1999, it is recommended that a sample of 315 units be evaluated to uncover any suspect signs of counterfeiting.
Once again there are many different scenarios that can be the trigger for this type of investigation. Whatever the trigger, this testing protocol is a good start to the process of identifying compromised counterfeit electronics to contain this evergrowing epidemic.
