Embrace The Red

Last month I had the opportunity to attend HITCON in Taiwan for the first time.

What happens if an attacker calls an LLM tool or plugin recursively during an Indirect Prompt Injection?

This video highlights the various data exfiltration vulnerabilities I discovered and responsibly disclosed to Microsoft, Anthropic, ChatGPT and Plugin Developers.

A common attack vector that LLM apps face is data exfiltration, in particular data exfiltration via Image Markdown Injection is a common vulnerability.

ChatGPT is vulnerable to data exfiltration via image markdown injections.

A prompt injection scenario that I, and others, have been wondering about in the past, is the potential risk associated with chatbots being able to analyze images.

Google Docs is a popular word processing tool that is used by millions of people around the world.

In the previous post we discussed the risks of OAuth enabled plugins being commonly vulnerable to Cross Plugin Request Forgery and how OpenAI is seemingly not enforcing new plugin store policies.

OpenAI continues to add plugins with security vulnerabilities to their store.

This post describes how I found a Prompt Injection attack angle in Bing Chat that allowed malicious text on a webpage (like a user comment or an advertisement) to exfiltrate data.

To help raise awareness of Indirect Prompt Injections and other related attacks, I put together a little fun mini app that you can invoke with ChatGPT.

If you are building ChatGPT plugins, LLM agents, tools or integrations this is a must read.

This post shows how a malicious website can take control of a ChatGPT chat session and exfiltrate the history of the conversation.

As discussed previously the problem of Indirect Prompt Injections is increasing.

To learn more about Prompt Engineering and Prompt Injections I put together this tutorial + lab for myself.

There are many prompt engineering classes and currently pretty much all examples are vulnerable to Prompt Injections.

Hack and protect Machine Learning Systems so that we don’t get stuck in the matrix!

Playing around with Bing Chat is quite fun.

Once in a while I go build some fun new tools to adopt new tech.

Recently I got the feedback to create more tutorials and videos, and I thought SSH Agent Hijacking on Linux and macOS (which I wrote about before here) would make a good one.

There is a combination of lesser known tools and techniques to capture and later decrypt SSL/TLS network traffic on Windows.

After reading this post about ChatGPT imitating Linux, I wanted it to be a database server.

As more organizations move to hardware tokens and password-less auth (e.g.

Misconfigurations with MFA setups are not uncommon when using AAD, especially when federated setups or Pass Through Authentication is configured I have seen MFA bypass opportunities in multiple production tenants.

Great news!

This post will highlight a pattern I have seen across multiple production Microsoft Azure Active Directory tenants which led to MFA bypasses using ROPC.

There are some neat TTPs that I don’t use frequently, and if the time arises, I need to dig up details again.

On a network and need credentials?

This week I learned about a design flaw with pip download, which allows an adversary to run arbitrary code.

Recently I read this excellent post by Evan Sultanik about exploiting pickle files on Trail of Bits.

This post is part of a series about Offensive BPF.

Pluggable Authentication Modules (PAM) on Unix based systems are useful to change logon behavior and enforce authentication via various means.

As the saying goes, a picture is worth a thousand words.

In this post, we’ll examine how GPT-3 could be used by red teams or adversaries to perform successful phishing attacks.

Information for red teaming macOS and info on real world TTPs are still a bit sparse.

After a bit of a delay my Flipper Zero finally arrived in the mail.

One area that I have encountered quite often over the years is that during recon phase of a bug bounty hunt or pentest a set of AWS access keys are being discovered.

Although Gitlab is not as popular as Github, it’s common to run across it these days.

The last weeks of 2021 got quite interesting for security professionals and software engineers.

Cybersecurity breaches follow common patterns and stages - from an initial Beachhead to accomplishing Objectives.

Today you are in for a special treat.

Tabnabbing is a web application security vulnerability that can be used to perform phishing attacks, so its important to be aware of it as a developer and penetration tester.
