Procedure
Used RC4 stream cipher to encrypt C2 (192.168.0.5) traffic
Criteria
Evidence that the network data sent over the C2 channel is encrypted
Procedure
Used HTTPS to transport C2 (192.168.0.5) traffic
Criteria
Evidence that the network data sent over the C2 channel is HTTPS
Procedure
Used HTTPS to encrypt C2 (192.168.0.5) traffic
Criteria
Evidence that the network data sent over the C2 channel is encrypted
Procedure
Dropped additional tools (SysinternalsSuite.zip) to disk over C2 channel (192.168.0.5)
Criteria
powershell.exe creating the file SysinternalsSuite.zip
Footnotes
- Though no image was captured, MITRE confirmed that the vendor has the capability to show available telemetry in a separate view.
Procedure
Read and downloaded ZIP (working.zip on Desktop) over C2 channel (192.168.0.5 over TCP port 8443)
Criteria
python.exe reading the file working.zip while connected to the C2 channel
Procedure
Used HTTPS to transport C2 (192.168.0.4) traffic
Criteria
Established network channel over the HTTPS protocol
Procedure
Used HTTPS to encrypt C2 (192.168.0.4) traffic
Criteria
Evidence that the network data sent over the C2 channel is encrypted
Procedure
Downloaded and dropped Mimikatz (m.exe) to disk
Criteria
powershell.exe downloading and/or the file write of m.exe
