S2 Dynamic Tracer And Decompiler For Gdb

Decompiling is very useful for understanding srtipped binaries, most dissasemblers like IDA or Hopper have a plugin for decompiling binaries, generating a c like pseudocode.

Static analysis, is very useful in most of cases, specially when the binary is not so big, or when you just have an address where to start to analyze. But some algorithms will be learned in less time by dynamic analysis like tracing or debugging.

In cookiemonsters team, we are working on several tracers with different focus, but all of them mix the concept of tracing and decompiling to generate human-readable traces.

S2 is my tracer & decompiler plugin for gdb, very useful for ctfs.
Some of the features are:

- signed/unsigned detecion
- conditional pseudocode (if)
- syscall resolution
- unroll bucles
- used registers values
- mem states
- strings
- logging

TorghostNG: Make All Your Internet Traffic Anonymized With Tor Network

About TorghostNG
   TorghostNG is a tool that make all your internet traffic anonymized with Tor network. TorghostNG is rewritten from TorGhost with Python 3.

   TorghostNG was tested on:
  • Kali Linux 2020a
  • Manjaro
  • ...

What's new in TorghostNG 1.2

Before you use TorghostNG
  • For the goodness of Tor network, BitTorrent traffic will be blocked by iptables. Although you can bypass it with some tweaks with your torrent client 😥 It's difficult to completely block all torrent traffic.
  • For security reason, TorghostNG is gonna disable IPv6 to prevent IPv6 leaks (it happened to me lmao).

Screenshots of Torghost (Version 1.0)
   Connecting to Tor exitnode in a specific country: torghostng -id COUNTRY ID

   Changing MAC address: torghostng -m INTERFACE

   Checking IP address: torghostng -c

   Disconnecting from Tor: torghostng -x

   Uninstalling TorghostNG: python3 install.py

Installing TorghostNG
   TorghostNG installer currently supports:
  • GNU/Linux distros that based on Arch Linux
  • GNU/Linux distros that based on Debian/Ubuntu
  • GNU/Linux distros that based on Fedora, CentOS, RHEL, openSUSE
  • Solus OS
  • Void Linux
  • Anh the elder guy: Slackware
  • (Too much package managers for one day :v)

   To install TorghostNG, open your Terminal and enter these commands:
   But with Slackware, you use sudo python3 torghostng.py to run TorghostNG :v

Help
    You can combine multiple choices at the same time, such as:
  • torghostng -s -m INTERFACE: Changing MAC address before connecting
  • torghostng -c -m INTERFACE: Checking IP address and changing MAC address
  • torghostng -s -x: Connecting to Tor anh then stop :v
  • ...
   If you have any questions, you can watch this tutorial videos 🙂
   I hope you will love it 😃

How to update TorghostNG
   Open Terminal and type sudo torghostng -u with sudo to update TorghostNG, but it will download new TorghostNG to /root, because you're running it as root. If you don't like that, you can type git pull -f and sudo python3 install.py.

Notes before you use Tor
   Tor can't help you completely anonymous, just almost:
   It's recommended that you should use NoScript before before surfing the web with Tor. NoScript shall block JavaScript/Java/Flash scripts on websites to make sure they won't reveal your real identify.

And please
  • Don't spam or perform DoS attacks with Tor. It's not effective, you will only make Tor get hated and waste Tor's money.
  • Don't torrent over Tor. If you want to keep anonymous while torrenting, use a no-logs VPN please.
   Bittorrent over Tor isn't a good idea
   Not anonymous: attack reveals BitTorrent users on Tor network

Changes log
   Version 1.2
  • Fixed update_commands and others in torghostng.py
  • Changed a few things in theme.py
  • Changed a few things in install.py
  • Now you can change Tor circuit with -r
   Version 1.1
  • Check your IPv6
  • Change all "TOR" to "Tor"
  • Block BitTorrent traffic
  • Auto disable IPv6 before connecting to Tor

Contact to the coder

To-do lists:
  • Block torrent, for you - Tor network (Done 😃)
  • Connect to IPv6 relays (maybe?)
  • GUI version
  • Fix bug, improve TorghostNG (always)

And finally: You can help me by telling me if you find any bugs or issues. Thank you for using my tool 😊
