Coding in Assembly is easy. It's like riding a bike. Except the bike is on fire & you're on fire & everything is on fire & you're in Hell.
I really hated Linux auditing until I found this. Couple it with Laurel and it becomes really easy to ingest these types of logs. Best of all, logging on linux is so rare most adversaries won't see it coming and get caught instantly. Demo here: youtube.com/watch?v=lc1i9h…

Just added support to LDAP Serialized Payloads in the JNDI-Exploit-Kit. This attack path works in *ANY* java version as long the classes used in the Serialized payload are in the application classpath. Do not rely on your java version being up-to-date and update your log4j ASAP!
