Each GET request then executes a Java code resembling the example below, wherein the final segment setPattern would be unique for each call (such as setPattern, setSuffix, setDirectory, and others): The .jsp file now contains a payload with a password-protected web shell with the following format: The attacker can then use HTTP requests to execute commands. Once executed in memory, the corrupter locates files in certain directories on the system with one of the following hardcoded file extensions: If a file carries one of the extensions above, the corrupter overwrites the contents of the file with a fixed number of 0xCC bytes (total file size of 1MB). A group linked to Iran took responsibility for the hack. Distribution of the encryption and wiping binaries was accomplished with two methods via a custom SMB remote file copy tool Mellona.exe, originally named MassExecuter.exe.
