Razer Mouse Grants Windows Admin Privileges

As the common saying goes, “all networked computers are vulnerable to exploits, but some networked computers are more vulnerable than others”. While not the exact wording from Animal Farm, the saying does have plenty of merit nonetheless. Sure, there are some viruses and issues with Linux distributions but by far most of the exploits target Windows, if only because more people use it daily than any other operating system. The latest Windows 10 exploit, discovered by [jonhat], is almost comically easy too, and involves little more than plugging in a mouse.

While slightly comforting in that an attacker would need physical access to the device rather than simple network access, it is very concerning how simple this attack is otherwise. Apparently plugging in a Razer mouse automatically launches Windows Update, which installs a driver for the mouse. The installation is run with admin privileges, and a Power Shell can be opened by the user simply by pressing Shift and right-clicking the mouse. While [jonhat] originally tried to let the company know, they weren’t responsive until he made the exploit public on Twitter, and are now apparently working on solving the issue.

Others have confirmed the exploit does in fact work, so hopefully there is a patch released soon that solves the issue. In the meantime, we recommend not allowing strangers to plug any devices into your personal computers as a general rule, or plugging in anything where its origins are unknown. Also remember that some attacks don’t required physical or network access at all, like this one which remotely sniffs keystrokes from a wireless keyboard with less than stellar security, also coincidentally built by Microsoft.

Razer Laptop Gets A Sneaky Fan Mod

Some people love fan noise, using it to help get to sleep or just create some ambience in a room. Others hate it, like [Dimitris], and will take severe measures to eliminate it where possible. When his Razer Blade laptop was incessantly whirring away, it was time to get to work.

The Razer laptop uses a controller that outputs a variable duty cycle signal to control fan speed. Unfortunately, the fans never fully switch off, even when the laptop is cold, leading to frustrating excessive noise. [Dimitris] implemented an ATtiny85 to intercept this signal, giving him full control over the fans. Two modes are implemented, one which keeps the fans off when the duty cycle is at its minimum, and the other that attempts to keep the fans at a minimum speed wherever possible.

While modifying the critical cooling system of a high-performance laptop is a risky business, it’s a decent price to pay for some peace and quiet. We’ve seen quite the opposite to this mod, too – like this Xbox 360 outfitted with additional cooling.

Hackaday Links: May 12, 2019

The future of the musical instrument industry is in tiny, cheap, handheld synthesizers. They’re sold as ‘musical toys’. They bleep and bloop, and that’s about it. Korg may have just released the minimum viable product for this category, and thus the most popular product for this category. On the surface, the Korg Nu:Tekt doesn’t look like much, just a box with three knobs, a speaker, a (crappy) keyboard, and a few buttons. I/O includes MIDI in, Sync in and out, audio in, and headphones out. What’s inside is what counts. There’s a high-powered ARM core (STM32F446, a Cortex-M4 running at 180 MHz) and a ton of RAM. What’s the play here? It’s compatible with the Korg Prologue/Minilogue SDK, so you can put the same sounds from the flagship synthesizer on a tiny box that fits in your pocket. Things are starting to get weird, man. This is a toy, with the same sounds as the ‘pro’ level synth. Let it be known that the synth market is the most interesting segment of consumer electronics right now.

Bird, that ride share scooter startup, is now selling their scooters. It costs thirteen hundred dollars. Alternatively, you can pick some up for cheap at your city’s impound lot. Or for the low, low, price of free.

Razer, the company that makes garish computer peripherals aimed at ‘gamers’ and other people who are sucked deep into the existential turmoil of disempowerment, depression, and playing video games all day, are building a toaster. Gamers aren’t known for eating food that isn’t prepared by their mom, but the Razer consumer community has been clamoring for a professional gaming toaster since it was first teased on April Fool’s Day three years ago. You only eat so many cold Pop Tarts straight out of the box, I guess.

Everyone loves cupcake cars, and this year we’re in for a treat! We’re ringing the bell this weekend with the 6th annual Hackaday x Tindie meetup for the Bay Area Maker Faire. We got a few things going on here. Next Thursday we’ll be greeted with talks by The Only Makers That You Want To Meet. That’s HDDG, the monthly San Francisco meetup happening at the Supplyframe office, and it’s going to be packed to the gills this month. Don’t miss it. Next Saturday, we’re renting a bar close to the Faire. The 6th Annual Hackaday x Tindie MFBA Meetup w/ Kickstarter is usually at an Irish pub in San Mateo, but we’re getting a bigger venue this year. You’ll be able to move around in this venue.
