Abstract
The disclosed embodiments provide a system that detects unwanted electronic components in a target computing system. During operation, the system obtains target electromagnetic interference (EMI) signals, which were gathered by monitoring EMI signals generated by the target computing system, using an insertable device, wherein when the insertable device is inserted into the target computing system, the insertable device gathers the target EMI signals from the target computing system. Next, the system generates a target EMI fingerprint from the target EMI signals. Finally, the system compares the target EMI fingerprint against a reference EMI fingerprint for the target computing system to determine whether the target computing system contains any unwanted electronic components.
