Description

The threat actor can overwrite a previously deployed/installed malicious program with a dummy program in order to evade the detection of the malicious program. This can be used to prevent detection by monitoring tools or engineering software that performs periodic “Program Uploads” to inspect the contents of a program on the device. While some devices utilize error detection codes, such as CRCs or Checksums, these are not cryptographically strong and a threat actor can easily generate a program with the same CRC/Checksum (i.e., by simply padding the program).
