What it detects

This rule detects a cmd chain that pings the loopback address with a repeat count to sleep and then deletes a file, the self cleanup and timing evasion used in the Blind Eagle campaign. Using ping as a sleep before deleting the dropper stalls sandboxes and removes artifacts after execution.
