[SOLVED] Typecatcher doesn't work [json.loads()] on Arch [AUR]

Typecatcher is an awesome tool to download and use Google Fonts offline, It's available on AUR & maintained by chelqo as on 8th April 2017.

It might have some dependency problems in your distribution so first we need to make sure that, we have all dependencies, please note that Typecatcher package requires following packages as dependencies, which are not installed as dependencies while installing from AUR in some cases.

In that case you have to get those dependencies installed, on your own. In my case following dependencies were missing

python-gobject 
webkitgtk

I installed following versions of the missing dependencies to get typecatcher working.

 python-gobject  3.22.0-2
webkitgtk  2.4.11-4

Commands to install missing dependencies.
sudo pacman -S python-gobject
sudo pacman -S webkitgtk
Even after installing the missing dependencies typecatcher refused to run on my system and displayed the following error message.
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/typecatcher_lib/Application.py", line 30, in on_activate
    self.window = TypeCatcherWindow.TypeCatcherWindow()
  File "/usr/lib/python3.6/site-packages/typecatcher_lib/Window.py", line 49, in __new__
    new_object.finish_initializing(builder)
  File "/usr/lib/python3.6/site-packages/typecatcher/TypeCatcherWindow.py", line 43, in finish_initializing
    self.fonts = FindFonts()
  File "/usr/lib/python3.6/site-packages/typecatcher/FindFonts.py", line 27, in FindFonts
    fonts = process_json(data)
  File "/usr/lib/python3.6/site-packages/typecatcher/FindFonts.py", line 50, in process_json
    json_data = json.loads(data, "utf-8")
TypeError: loads() takes 1 positional argument but 2 were given
In my case I had to edit two files myself, if you are also getting similar error messages after installing missing dependencies then the following fix is likely to solve your problems.

Run the following command.
sudo nano /usr/lib/python3.6/site-packages/typecatcher/FindFonts.py
 In the def process_json(data):
Add "encoding=" before "utf-8"
Then it should look like this
json_data = json.loads(data, encoding="utf-8")
Use Ctrl X to EXIT and Press "Y" to Confirm then Hit ENTER

After this fix, typecatcher GUI should start. In my case I was getting following error while downloading fonts.
Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/typecatcher/TypeCatcherWindow.py", line 243, in on_download_btn_clicked
    DownloadFont(self.font, uri=None)
  File "/usr/lib/python3.6/site-packages/typecatcher/DownloadFont.py", line 31, in DownloadFont
    font_dict = extract_url(font_name)
  File "/usr/lib/python3.6/site-packages/typecatcher/DownloadFont.py", line 61, in extract_url
    json_data = json.loads(str(data), "utf-8")
TypeError: loads() takes 1 positional argument but 2 were given
We have to follow same procedure to fix this error.
Run the following command. 
sudo nano /usr/lib/python3.6/site-packages/typecatcher/DownloadFont.py
In the def extract_url(family):
Add "encoding=" before "utf-8"
Then it should look like this
json_data = json.loads(data, encoding="utf-8")
Use Ctrl X to EXIT and Press "Y" to Confirm then Hit ENTER

After this you should be able to launch typecatcher and install fonts to your system without any errors.

Site wide CSRF on a popular program

Image
I found this bug in the same program that I explained in this post " Authorization bug every bug hunter missed " I was moving through another target on this program when I noticed that there was no CSRF protection like there were no tokens etc so I wondered what they were using to prevent CSRF, I noticed some high entropy strings in headers but request worked without those headers as well so that wasn't protecting the website from CSRF. Request body consisted of JSON objects basically {key: "value"} pairs the assumption behind using it was that in a typical CSRF attack attackers don't send JSON payloads, so using JSON will naturally protect the application against CSRF. Here's where the trick comes in, It's actually more of check that you should perform while trying to find CSRF bugs, I spotted it on Twitter first you may or may not be familiar with it, here's how it works. It's very simple assume that server side framework is expe

Releasing Flumberbuckets: S3 Bucket Enumeration Tool for Bug Hunters

Image
Flumberbuckets is a part of suite of scripts that I'll be open-sourcing on GitHub in flumberboozle repository, scripts in this repository are supposed to aid bug hunters in hunting, automating workflows, etc. There is also another script in flumberboozle repository which is a portscanner with scan auto-save, auto-startup function called portboozle. What is flumberbuckets? Flumberbuckets is is yet another S3 bucket enumeration tool which you can choose to use while hunting on bug bounty programs or during security assessment. I designed this tool to serve my purposes and now I am open-sourcing it, there are several different tools that exist for people with different tastes. The aim of this tools was to present S3 bucket enumeration results in better format which is visually more appealing than scrolling through output of a bash script that just runs   aws s3 ls  in a loop. How does it work? Flumberbuckets is a really simple script which combines the best of existing S3 bucke

Installing XFCE & other things on Arch Linux

Image
How to do a complete Arch Linux install with XFCE, LightDM, Udisks, Yaourt, and other essentials Arch Linux is a lightweight Linux distribution and installing Arch Linux teaches you a lot about how system works under the hood, after you've installed Arch you'll start to appreciate command line and Arch's install procedure. I used to like distributions such as Parrot and Ubuntu because they already had packages installed and configured for me, but the point of installing Arch is to learn about Linux system. Learning core components of Linux and knowing which packages you've installed will also help you in fixing problems which might arise in the future, also building a system from command line is fun. Like Arch, XFCE Desktop Environment is also lightweight, minimal, and not resource hungry. Though XFCE is simple and lightweight it has some modern features, and if you customize it like me, It'd look really cool while taking about 200 MB to 300 MB of your m
