Detects a two-stage attack chain where a host downloads an image file from the network, followed by the execution of suspicious system binaries (e.g., mshta, powershell, rundll32). This pattern is characteristic of steganographic loaders like CloudEyE or DBatLoader used to extract and execute payloads like Remcos RAT.
