Background
Written in Delphi, ELMER is a non-persistent, proxy-aware HTTP backdoor that supports uploading and downloading files, running executables, and enumerating processes and directories. It fetches instructions by issuing HTTP GET requests to a hard-coded CnC server and then parsing the server's HTTP responses for an integer string that identifies which command to run.
