Flopped Humane “AI Pin” Gets An Experimental SDK

June 19, 2025 by Donald Papp 10 Comments

The Humane AI Pin was ambitious, expensive, and failed to captivate people between its launch and shutdown shortly after. While the units do contain some interesting elements like the embedded projector, it’s all locked down tight, and the cloud services that tie it all together no longer exist. The devices technically still work, they just can’t do much of anything.

Since then, developers like [Adam Gastineau] have been hard at work turning the device into an experimental development platform: PenumbraOS, which provides a means to allow “untrusted” applications to perform privileged operations.

As announced earlier this month on social media, the experimental SDK lets developers treat the pin as a mostly normal Android device, with the addition of a modular, user-facing assistant app called MABL. [Adam] stresses that this is all highly experimental and has a way to go before it is useful in a user-facing sort of way, but there is absolutely a workable architecture.

When the Humane AI Pin launched, it aimed to compete with smartphones but failed to impress much of anyone. As a result, things folded in record time. Humane’s founders took jobs at HP and buyers were left with expensive paperweights due to the highly restrictive design.

Thankfully, a load of reverse engineering has laid the path to getting some new life out of these ambitious devices. The project could sure use help from anyone willing to pitch in, so if that’s up your alley be sure to join the project; you’ll be in good company.

This Week In Security: Roundcube, Unified Threat Naming, And AI Chat Logs

June 6, 2025 by Jonathan Bennett 4 Comments

Up first, if you’re running a Roundcube install prior to 1.5.10 or 1.6.11, it’s time to update. We have an authenticated Remote Code Execution (RCE) in the Roundcube Webmail client. And while that’s not quite the level of chaos that an unauthenticated RCE would cause, it’s still to be taken seriously. Mainly because for the majority of the 53 million Roundcube installs out there, the users aren’t entirely trusted.

The magic at play in this vulnerability is the Roundcube user session code, and specifically the session deserialization scheme. There’s a weird code snippet in the unserialize function:
if ($str[$p] == '!') { $p++; $has_value = false;

The exclamation mark makes the code skip a character, and then assume that what comes next has no value. But if it does actually have a value, well then you’ve got a slightly corrupted deserialization, resulting in a slightly corrupted session. This really comes into force when combined with the file upload function, as the uploaded filename serves as a payload delivery mechanism. Use the errant exclamation mark handling to throw off deserialization, and the filename can contain arbitrary session key/value pairs. A GPG class from the PEAR library allows running an arbitrary command, and this can be hijacked with the session manipulation.

This Week In Security: CIA Star Wars, Git* Prompt Injection And More

May 30, 2025 by Jonathan Bennett 3 Comments

The CIA ran a series of web sites in the 2000s. Most of them were about news, finance, and other relatively boring topics, and they spanned 29 languages. And they all had a bit of a hidden feature: Those normal-looking websites had a secret login and hosted CIA cover communications with assets in foreign countries. A password typed in to a search field on each site would trigger a Java Applet or Flash application, allowing the spy to report back. This isn’t exactly breaking news, but what’s captured the Internet’s imagination this week is the report by [Ciro Santilli] about how to find those sites, and the fact that a Star Wars fansite was part of the network.

This particular CIA tool was intended for short-term use, and was apparently so effective, it was dragged way beyond it’s intended lifespan, right up to the point it was discovered and started getting people killed. And in retrospect, the tradecraft is abysmal. The sites were hosted on a small handful of IP blocks, with the individual domains hosted on sequential IP addresses. Once one foreign intelligence agency discovered one of these sites, the rest were fairly easily identified.

Hackaday Links: May 25, 2025

May 25, 2025 by Dan Maloney 24 Comments

Have you heard that author Andy Weir has a new book coming out? Very exciting, we know, and according to a syndicated reading list for Summer 2025, it’s called The Last Algorithm, and it’s a tale of a programmer who discovers a dark and dangerous secret about artificial intelligence. If that seems a little out of sync with his usual space-hacking fare such as The Martian and Project Hail Mary, that’s because the book doesn’t exist, and neither do most of the other books on the list.

The list was published in a 64-page supplement that ran in major US newspapers like the Chicago Sun-Times and the Philadelphia Inquirer. The feature listed fifteen must-read books, only five of which exist, and it’s no surprise that AI is to behind the muck-up. Writer Marco Buscaglia took the blame, saying that he used an LLM to produce the list without checking the results. Nobody else in the editorial chain appears to have reviewed the list either, resulting in the hallucination getting published. Readers are understandably upset about this, but for our part, we’re just bummed that Andy doesn’t have a new book coming out.

This Week In Security: Signal DRM, Modern Phone Phreaking, And The Impossible SSH RCE

May 23, 2025 by Jonathan Bennett No comments

Digital Rights Management (DRM) has been the bane of users since it was first introduced. Who remembers the battle it was getting Netflix running on Linux machines, or the literal legal fight over the DVD DRM decryption key? So the news from Signal, that DRM is finally being put to use to protect users is ironic.

The reason for this is Microsoft Recall — the AI powered feature that takes a snapshot of everything on the user’s desktop every few seconds. For whatever reason, you might want to exempt some windows from Recall’s memory window. It doesn’t speak well for Microsoft’s implementation that the easiest way for an application to opt out of the feature is to mark its window as containing DRM content. Signal, the private communications platform, is using this to hide from Recall and other screenshotting applications.

The Signal blogs warns that this may be just the start of agentic AI being rolled out with insufficient controls and permissions. The issue here isn’t the singularity or AI reaching sentience, it’s the same old security and privacy problems we’ve always had: Too much information being collected, data being shared without permission, and an untrusted actor having access to way more than it should.

Christmas Comes Early With AI Santa Demo

May 18, 2025 by Tyler August 6 Comments

With only two hundred odd days ’til Christmas, you just know we’re already feeling the season’s magic. Well, maybe not, but [Sean Dubois] has decided to give us a head start with this WebRTC demo built into a Santa stuffie.

The details are a little bit sparse (hopefully he finishes the documentation on GitHub by the time this goes out) but the project is really neat. Hardware-wise, it’s an audio-enabled ESP32-S3 dev board living inside Santa, running the OpenAI’s OpenRealtime Embedded SDK (as implemented by ExpressIf), with some customization by [Sean]. Looks like the audio is going through the newest version of LibPeer and the heavy lifting is all happening in the cloud, as you’d expect with this SDK. (A key is required, but hey! It’s all open source; if you have an AI that can do the job locally-hosted, you can probably figure out how to connect to it instead.)

This speech-to-speech AI doesn’t need to emulate Santa Claus, of course; you can prime the AI with any instructions you’d like. If you want to delight children, though, its hard to beat the Jolly Old Elf, and you certainly have time to get it ready for Christmas. Thanks to [Sean] for sending in the tip.

If you like this project but want to avoid paying OpenAI API fees, here’s a speech-to-text model to get you started.We covered this AI speech generator last year to handle the talky bit. If you put them together and make your own Santa Claus (or perhaps something more seasonal to this time of year), don’t forget to drop us a tip!

MCP Blender Addon Lets AI Take The Wheel And Wield The Tools

May 18, 2025 by Donald Papp 8 Comments

Want to give an AI the ability to do stuff in Blender? The BlenderMCP addon does exactly that, connecting open-source 3D modeling software Blender to Anthropic’s Claude AI via MCP (Model Context Protocol), which means Claude can directly use Blender and its tools in a meaningful way.

MCP is a framework for allowing AI systems like LLMs (Large Language Models) to exchange information in a way that makes it easier to interface with other systems. We’ve seen LLMs tied experimentally into other software (such as with enabling more natural conversations with NPCs) but without a framework like MCP, such exchanges are bespoke and effectively stateless. MCP becomes very useful for letting LLMs use software tools and perform work that involves an iterative approach, better preserving the history and context of the task at hand.

Unlike the beach scene above which used 3D assets, this scene was created from scratch with the help of a reference image.

Using MCP also provides some standardization, which means that while the BlenderMCP project integrates with Claude (or alternately the Cursor AI editor) it could — with the right configuration — be pointed at a suitable locally-hosted LLM instead. It wouldn’t be as capable as the commercial offerings, but it would be entirely private.

Embedded below are three videos that really show what this tool can do. In the first, watch it create a beach scene using assets from a public 3D asset library. In the second, it creates a scene from scratch using a reference image (a ‘low-poly cabin in the woods’), followed by turning that same scene into a 3D environment on a web page, navigable in any web browser.

Back in 2022 we saw Blender connected to an image generator to texture objects, but this is considerably more capable. It’s a fascinating combination, and if you’re thinking of trying it out just make sure you’re aware it relies on allowing arbitrary Python code to be run in Blender, which is powerful but should be deployed with caution.
