CISA and CNMF Analysis of SolarWinds-related Malware

CISA and the Department of Defense (DoD) Cyber National Mission Force (CNMF) have analyzed additional SolarWinds-related malware variants—referred to as SUNSHUTTLE and SOLARFLARE. One of the analyzed files was identified as a China Chopper webshell server-side component that was observed on a network with an active SUNSHUTTLE infection. The webshell can provide a cyber threat actor an alternative method of accessing a network, even if the SUNSHUTTLE infection was remediated.
