Temperature and Humidity readings capture using DHT22/AM2302 on Raspberry PI

Following from the previous article, in this one we are going to record temperature and humidity using the following setup, a link to the wiring can be found below.

**A humble setup**



**the wiring diagram***



First, follow the instructions to install wiringpi here. Further download and make the program to access the sensor readings,

cd /opt/
git clone https://github.com/technion/lol_dht22
cd lol_dht22
./configure
make

here's the output

pi@raspberrypi:~/lol_dht22 $ sudo ./loldht 7
Raspberry Pi wiringPi DHT22 reader
www.lolware.net
Humidity = 55.20 % Temperature = 27.20 *C

 #7 is the Pi1 mobel B GPIO pin#

The correct way to install Jython (for Burpsuite)

You need to install Jython the correct way in order to ensure some of the Burp plugins work correctly. Some of these Burp plugins depend on Python libraries for e.g. requests, so installing Jython and then using  $ wget https://repo1.maven.org/maven2/org/python/jython-installer/2.7.2/jython-installer-2.7.2.jar $ java -jar jython-installer-2.7.2.jar -s -d /path/to/install/jython -t standard Further for e.g. if you need requests install it like this: Download requests-2.25.1.tar.gz from the official repo ( https://pypi.org/project/requests/#files ), then go to that directory in terminal, and type the following command, java -jar /Users/brutus/Downloads/jython-standalone-2.7.2.jar setup.py install

RFID cloning with Proxmark3 Easy

Image
In this post, I would like to explain how in a recent Red Team engagement, I successfully managed to clone an RFID Access Control card and gained entry into the premise. #TheKit The client was using HiD 125khz cards. I used "Proxmark 3 Easy" which is a low cost RFID cloning kit, is a stripped down version of the real “ Proxmark 3 RDV 2 ”. The "Proxmark3 easy" does not support several things like battery, relaying and doesn't have an amplifier, also it has a smaller memory. But the device is quite sufficient during a Red Team Physical engagement. It looks something like this when you order on Amazon. I wanted to build a mobile RFID cloning kit and use it for my Red Team engagements, but note with this setup the scanning distance of 6cm is useless in real engagements, I'm not that brave enough and you really have to get up close to clone a card so the setup initially didn't work, however I got lucky and me and my partner found a lost targe

Extracting an IPA; App distributed through Testflight

So in one of my iOS app pentest the app was distributed on TestFlight, I needed a clean IPA to makesure, I review the app after unpacking it. The option was for me to use a Jailbroken device and use Ext3nder, which allows the app to be re-packaged. Once you do that you could use SCP to download the IPA and use it to analyse or side load through xCode.
