For one of my old projects last year, I need mod a micro servo to rotate continuously 360 degrees for a small robot tank, this hack will work with just about any servo. To do so you need to for open up the servo casing. Carefully remove the bottom portion first (where the wires are coming out of). Continue reading →
Affected configurations: All versions of OpenSSH prior to 7.2p2 with X11Forwarding enabled.
Vulnerability: Missing sanitisation of untrusted input allows an authenticated user who is able to request X11 forwarding to inject commands to xauth(1).
Injection of xauth commands grants the ability to read arbitrary files under the authenticated user’s privilege, Other xauth commands allow limited information leakage, file overwrite, port probing and generally expose xauth(1), which was not written with a hostile user in mind, as an attack surface.
Mitigation / Workaround:
disable x11-forwarding: sshd_config set X11Forwarding no
disable x11-forwarding for specific user with forced-commands: no-x11-forwarding in authorized_keys
Researchers, Kai Cao and Anil Jain, from the Department of Computer Science and Engineering at Michigan State University have loaded up an inkjet printer with cartridges designed for printing electronic circuits, and used the output to fool smartphone fingerprint sensors on a Samsung Galaxy S6 and a Huawei Honor 7. They just needed a reversed scan of the victim’s fingerprint, and an inkjet printer loaded up with ink and paper from printed electronics specialist AGIC. Read more of their paper ::HERE::
All installations having Exim set-uid root and using ‘perl_startup’ are
vulnerable to a local privilege escalation. Any user who can start an
instance of Exim (and this is normally *any* user) can gain root
privileges. ::POC Here::
Got my new RPi3 today , I was able to get it ordered early Monday morning by poking around Element14’s website. Even though they didn’t have it posted they did an available part number, 77Y6520, so I used that to place an order and I got notified on Tuesday that it was sent 🙂 The CPU is a little beefier and its 64bit and the board now has wifi and bluetooth onboard. So I’ll probably implement some bluetooth geo-fencing with IFTTT in my home automation project.
Using Flask and JQuery, a friend helped me out with automating capturing the 433mhz signal from remotes so you don’t have to manually add them in the code.
Basically the Flask starts a webserver when you click n the add button, the code executes the RFSniffer binary and receives the data when a signal is received, then displays it to the webpage. Still have to finish the code for adding the data to the MySQL db , but thats the easy part.
So I received an official 7″ touch display for xmas. Even though it’s $60, it brings my total cost over 200$ for the project. But I thought it would be an awesome addition to the project because you don’t have to whip out your phone just to control everything. I’s a pretty sweet 800 x 480 10 point capacitive touchscreen display all you need to do is connect the DSI ribbon cable and feed ground/5v from the Pi’s GPIO pins. Im thinking starting the browser in kiosk mode should suffice once I finish the node.js interface. The only issue I havent resolved was to power down the screen fully when the Pi shutdowns. If anyone knows how to let me know.
Working on mini MAME arcade machine. It was designed in Solid Works 2015 then cut out of 1/4″ MDF on our Epilog laser cutter. Will be powered by a Raspberry Pi and a 9″ TFT screen. The software is MAME4ALL-Pi running the MAME 0.375b5 romsets. The joystick and buttons are connected directly to the GPIO pins and the 9” monitor is connected to the Video out port.
Pilybius is based off an arcade cabinet described in an urban legend about a game called Polybius, which is said to have induced various psychological effects on players. The story describes players suffering from amnesia, night terrors, and a tendency to stop playing all video games.
Bizarre rumors about this game are that it was supposedly developed by some kind of weird military tech offshoot group, used some kind of proprietary behavior modification algorithms developed for the CIA. According to an operator who ran an arcade with one of these games, guys in black coats would come to collect “records” from the machines. They’re not interested in quarters or anything, they just collected information about how the game was played.
Around a month after its supposed release in 1981, Polybius is said to have disappeared without a trace. There is no evidence that such a game has ever existed.
