Recently I needed to get the data off of a LUKS encrypted partition on a Virtual Machine that “wasn’t mine” and I’d never done it before.

In iOS if you are: Using Apple Maps for directions Playing Music Connected to a car over Bluetooth (not Apple CarPlay) …when you pause your music it will remain paused until the next direction is audibly announced by Apple Maps.

In this blog, the second in the series, you will learn about how to build a database of Bluetooth Low-Energy (BTLE) Generic Attribute (GATT) Universally Unique Identifiers (UUIDs) capable of remotely identifying Bluetooth Low-Energy devices for the purposes of vulnerability research, exploitation, and quantifying impact.

Recently Sift caught an interesting payload. As it turns out, the exploit was CVE-2024-0769, which is now tagged here: D-Link DIR-859 Information Disclosure Attempt .

The M5Stack CoreMP135 w/ STM32MP135D is a versatile little DevKit recently released by M5Stack at the $75 price range. I’m a big fan of M5Stack and have purchased many of their kits over the years, with each kit being versatile enough to have served for 10+ projects each over it’s lifetime without issue.

For this last years Binary Golf Grand Prix the goal was to: Create the smallest self-replicating file. Requirements:

On April 18th, 2020 during peak COVID I did my first real foray into Bluetooth Low-Energy (BTLE) privacy and security. A neighbor in my apartment complex lost their Fitbit Charge 2 smartwatch.

In order to see CVE-2023-50164 in the wild, I expect that in the coming weeks, we will see research into vendor and product specific implementations leveraging Apache Struts2 in order to determine exactly what path must be traversed to in order to drop a web shell so that it can be called remotely through a public interface over the defined routes.

Do you know all of the default Windows file formats? I’ve certainly seen a few in my time, though I can’t say I’ve seen a corpus of all the samples in one place.

At GreyNoise we work with network protocols. When a new vulnerability is published we are quick to jump into investigation mode and gather any and all resources we can find in order to write a tag and provide messaging to our customers and community.

Hello, we’re going to be trying something a little bit different today. A colleague recommended this whisper.cpp thing, which is a port of open.

The real motive of this series of blogs may take a few iterations to become clear to the reader, assuming of course I can actually pull it off.

This blog is far overdue and unfortunately isn’t really a “Part 1”. The truth is, I’ve poked around with Wi-Fi Direct for several months now with mild success and many dead-ends that resulted in learning a lot.

For this years Binary Golf Grand Prix I started off by learning to fuzz properly, use a debugger properly, and various tooling.

The 3rd Annual Binary Golf Grand Prix (BGGP3) is to find the smallest file which will crash a specific program.

Where we last left off, I had done an initial reverse engineering pass of Windows Update Delivery Optimization see: DOing Harm.

There’s this thing called Windows Delivery Optimization which allows “you to get Windows updates and Microsoft Store apps from sources in addition to Microsoft, like other PCs on your local network, or PCs on the internet that are downloading the same files.

Where last I left off in Adventures in Bluetooth: Part 1, I was originally attempting to flash custom firmware to a Fitbit Charge 2 smartwatch and ended up taking a quite large side-quest.

Have you ever had an idea you couldn’t quite shake? Something that worms it’s way into your brain for one reason or another and just wont leave.

I was a Private Internet Access (PIA) customer for many, many years. Some recent changes spurred me to look for a new VPN provider and I ended up landing on ProtonVPN which I’ve been using for a few months now.

Symbian OS, Android, Radio Frequencies, BTSNOOZ, BTSNOOP, and getting kicked in the teeth. Below follows a chronicling of deciding to explore Bluetooth by hacking the firmware for a Fitbit Smartwatch and realizing I was in way over my head and slowly trying to regain any hope of understanding.

So far I’ve managed to have just enough reverse engineering skills as is useful to me at the time, but recently I’ve taken an interest in getting a bit more in depth.

Recently I stumbled across a thread on Reddit r/AskNetsec Now, without looking at the post: What do you think the answers looked like?

Last week a friend of mine asked me to debug/RE some phishing emails that had been sent to them. These phishing emails were visually very clever and looked identical to the real site!

It’s easy to set up an IDS or other infrastructure to drop packets that match rules. There are many tools for real-time inspection of connections that can handle higher level protocols like HTTP or TLS.
