Prereqs: Verify you have both `script` and `scriptreplay` installed. Chances are `script` is pre-installed, but you may need:
sudo apt install bsdutils For scriptreplay
Recording Terminal Sessions with `script`
The `script` command logs all terminal input/output to a file:
script ~/terminal_session.log
Everything you type and see will be saved until you exit.
Advanced: Real-Time Replay with `scriptreplay`
For cybersecurity demonstrations or training, use:
script --log-timing time.log --log-out session.out
– Run commands (e.g., top, ps aux, find /var).
– Type `exit` to stop recording.
Replay the session in real time:
scriptreplay --log-timing time.log --log-out session.out
You Should Know:
1. Forensic Analysis with `script`
- Capture attacker activity during incident response:
script --append --timing=attack.tm --log-out attack.log
– `–append` ensures logs aren’t overwritten.
2. Automate Logging for Audits
Add to `~/.bashrc` to auto-log all root sessions:
if [ "$(whoami)" = "root" ]; then script --timing=/var/log/root_time.log --log-out=/var/log/root_session.log fi
3. Convert Logs to Readable Formats
Use `cat` or `less` for static logs:
cat session.out
Or filter sensitive data before sharing:
grep -v "password" session.out > clean_session.log
4. Windows Equivalent: `PSReadLine`
For PowerShell session logging:
Start-Transcript -Path "C:\logs\powershell_session.txt"
Stop with:
Stop-Transcript
5. Replay Speed Control
Adjust replay speed (e.g., 2x faster):
scriptreplay --log-timing time.log --log-out session.out --divisor 2
What Undercode Say:
– `script` is invaluable for penetration testing documentation.
– Combine with `tmux` for multi-window logging.
– Use `gzip` to compress large logs:
gzip session.out
– For automated red-team ops, integrate with cron:
0 /usr/bin/script /var/log/hourly_session_$(date +\%Y\%m\%d).log
Expected Output:
A real-time replay of your terminal session, useful for:
– Training (demonstrating exploits).
– Incident reports (proving system compromises).
– Debugging (retracing steps).
Prediction:
As AI-driven attacks rise, terminal logging will evolve with ML-based anomaly detection to flag suspicious commands in real time.
