Java class to generate a Groovy serialized payload
View ManualPayloadGenerate.java
/*
DiabloHorn - https://diablohorn.com
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

View YubiHSM2 Backed SSH Certificates
### 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:

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.
