Background
Mandiant describes VaporRage, also called BOOMMIC, as a C-based shellcode downloader that uses HTTPS for its communications. It pulls shellcode payloads from a hardcoded C2, identifying the host with an encoded host_id derived from the target's domain and account name. BOOMMIC then XOR-decodes the retrieved shellcode in memory and runs it.
