Detects the execution of concatenated commands via "cmd.exe". Pikabot often executes a combination of multiple commands via the command handler "cmd /c" in order to download and execute additional payloads.
Commands such as "curl", "wget" in order to download extra payloads. "ping" and "timeout" are abused to introduce delays in the command execution and "Rundll32" is also used to execute malicious DLL files.
In the observed Pikabot infections, a combination of the commands described above are used to orchestrate the download and execution of malicious DLL files.

This query was originally published in the threat analytics report, Confluence and WebLogic abuse.
2019 has seen several seemingly related campaigns targeting Atlassian Confluence Server and Oracle WebLogic Server. Although these campaigns use different implants and delivery methods, they consistently use the same infrastructure, and exploit the same vulnerabilities.
