Editor's Notes
- Zoom: alt cmd +
- Passive Scanning: Scan requests already made and won’t send any new requests
- Cmd to generate random numbers: Fail case: jot -r 20001 1 400000 | tee tokens-larger Pass case: for i in ` seq 1 5000 `; do uuidgen | tee -a tokens-uuid; done
- Find in Comments, Scripts are available only from Target.
