Purpose

Bootstrap knowledge of LLMs ASAP. With a bias/focus to GPT.

Avoid being a link dump. Try to provide only valuable well tuned information.

Prelude

Neural network links before starting with transformers.

ChatGPT Builds A Rudimentary Whiteboarding App

Here's the conversation I had collaborating with ChatGPT to build a basic diagramming app.

Features

Canvas based rendering
You can create rectangles (click to create a rectangle)
You can move rectangles (click on Move Rectangle)
You can change the fill color of rectangles (Click on Change Color, then click on a rectangle to randomly assign it a fill color)

Notes

Certifried combined with KrbRelayUp

Certifried (CVE-2022-26923) gives Domain Admin from non-privileged user with the requirement adding computer accounts or owning a computer account. Kerberos Relay targeting LDAP and Shadow Credentials gives a non-privileged domain user on a domain-joined machine local admin access on (aka owning) the machine. Combination of these two: non-privileged domain user escalating to Domain Admin without the requirement adding/owning computer accounts.

The attack below uses only Windows (no Linux tools interacting with the Domain), simulating a real-world attack scenario.

Prerequisites:

Script and the decoded strings from the EKANS/Snake ransomware. Original script written by @sysopfb - I've only modified the regexp to cover all cases where decryption was used in the sample.

Script:

import re
import sys
import pefile
import struct

Based on the Host communication instructions, but with a tweak for when the usb0 address is not found:

$ /sbin/ip link set usb0 up
Cannot find device "usb0"

Because of the predictable network interface name scheme, though, usb0 may be renamed to something else:
