Capture Wireless Traffic

Wireless Frame Format

Using Tcpdump

tcpdump -i <interface> -s 0 -nne 'wlan type <type> subtype <subtype>'

Note older versions of tcpdump and wireshark capture filter dosn't support the "wlan" keyword, just use "type <type> subtype <subtype>"

Sniffing wireless in monitor mode, ignore beacon's

tcpdump -i <interface> -s 0 -nne '(type mgt or type ctl or type data) and (not type mgt subtype beacon)'

type	subtype
mgt	assoc-req
	assoc-resp
	reassoc-req
	reassoc-resp
	probe-req
	probe-resp
	beacon
	atim
	disassoc
	auth
	deauth
ctl	ps-poll
	rts
	cts
	ack
	cf-end

Wlan Capture

Using Wireshark

wlan.fc.type == 0           Management frames
wlan.fc.type == 1           Control frames
wlan.fc.type == 2           Data frames
wlan.fc.type_subtype == 0   Association request
wlan.fc.type_subtype == 1   Association response
wlan.fc.type_subtype == 2   Reassociation request
wlan.fc.type_subtype == 3   Reassociation response
wlan.fc.type_subtype == 4   Probe request
wlan.fc.type_subtype == 5   Probe response
wlan.fc.type_subtype == 8   Beacon
 
wlan.addr = 12:34:56:AB:CD:EF  Select frames where any of the four address
                               fields matches the given MAC address.

Hacking Windows 10 UWP App: DLL Injection & common Vulnerabilities

I recently started working on widows 10 Apps( Apps not Applications) security. Before diving deep in hacking terms lets try to understand what's new in Windows 10 UWP( Universal Platform) as compared to old Apps. Lets begin with how apps actually work on windows 10(desktop/tablet). Now windows 10 comes with a container only for running apps inside the isolated environment. By default, /APPCONTAINER(Linker Flag) is off. This option modifies an executable to indicate whether the app must be run in the appcontainer process-isolation environment. Specify /APPCONTAINER for an app that must run in the appcontainer environment—for example, a Windows Store app. (The option is set automatically in Visual Studio when you create a Windows Store app from a template.) For a desktop app, specify /APPCONTAINER:NO or just omit the option. The /APPCONTAINER option was introduced in Windows 8. Now there is no registry entry concept for these app in the System HIVE rather they install they own hiv

SSI Injection Attack

SSIs are directives present on Web applications used to feed an HTML page with dynamic contents. They are similar to CGIs, except that SSIs are used to execute some actions before the current page is loaded or while the page is being visualized. In order to do so, the web server analyzes SSI before supplying the page to the user. The Server-Side Includes attack allows the exploitation of a web application by injecting scripts in HTML pages or executing arbitrary codes remotely. It can be exploited through manipulation of SSI in use in the application or force its use through user input fields. It is possible to check if the application is properly validating input fields data by inserting characters that are used in SSI directives, like: Code: < ! # = / . " - > and [a-zA-Z0-9] Another way to discover if the application is vulnerable is to verify the presence of pages with extension .stm, .shtm and .shtml. However, the lack of these type of pages does not mean that th
