## Overview
Following the initial access via COVID-19 themed phishing emails, the Mustang Panda APT group has proceeded to execute the PlugX malware on compromised systems.

## Technical Details
The executed PlugX variant exhibits typical characteristics associated with the malware family. It uses DLL side-loading techniques to bypass security mechanisms and gain a foothold on the victim's machine. Notably, the malware disguises itself as legitimate software processes, making detection challenging.

## Indicators of Compromise (IOCs)
- **File Hashes:** Multiple unique hashes have been identified corresponding to the PlugX binaries. 
- **Network Traffic:** Unusual outbound connections to known C2 domains used by Mustang Panda.

## Recommendations
- Conduct a thorough scan of network systems for the identified IOCs.
- Ensure that endpoint protection solutions are updated to detect and block PlugX malware.

## Next Steps
With PlugX execution confirmed, the operation is likely to progress towards establishing persistence and initiating data exfiltration efforts.
