Due to the enormous distribution and the multitude of plugins, WordPress is also a very popular target for attackers. This cheat sheet focuses on the wp-config.php file a...

kernel: Division by zero in change_port_settings in drivers/usb/serial/io_ti.c resulting in a denial of service

A division-by-zero in settermios, when debugging is enabled, was found in the Linux kernel. When the ioti driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the changeportsettings in the drivers/usb/serial/ioti.c so that the divisor value becomes zero and...

PowerShell Front-End for Windows Debugger Engine: DbgShell

The main impetus for DbgShell is that it’s just waaaay too hard to automate anything in the debugger. There are facilities today to assist in automating the debugger, of course. But in my opinion they are not meeting people’s needs. Using the built-in scripting language is arcane, limited,...

Web-Traffic-Generator - A Quick And Dirty HTTP/S "Organic" Traffic Generator

Just a simple poorly written Python script that aimlessly "browses" the internet by starting at pre-defined rootURLs and randomly "clicking" links on pages until the pre-defined clickDepth is met. I created this as a noise generator to use for an Incident Response / Network Defense simulation. Th...
