Network administrators often utilize Pre-boot Execution Environment (PXE) to rapidly deploy new systems on a network easily. Golden system images can be created with all the software and settings already in place for new systems. In this episode of Tradecraft Security Weekly Beau Bullock (@dafthack) discusses some of the potential attack vectors surrounding PXE boot deployments.

Organizations are implementing two-factor on more and more web services. The traditional methods for phishing credentials is no longer good enough to gain access to user accounts if 2FA is setup. In this episode Mike Felch (@ustayready) and Beau Bullock (@dafthack) demonstrate a tool that Mike wrote called CredSniper that assists in cloning portals for harvesting two-factor tokens.
In this episode of Tradecraft Security Weekly hosts Beau Bullock (@dafthack) and Mike Felch (@ustayready) discuss methods for evading network-based detection mechanisms. Many commercial IDS/IPS devices do a pretty decent job of detecting standard pentesting tools like Nmap when no evasion options are used. Additionally, companies are doing a better job at detecting and blocking IP addresses performing password attacks. Proxycannon ...
It is fairly common for pentesters to discover Cross-Site Scripting (XSS) vulnerabilities on web application assessments. Exploiting these issues potentially allow access to a user's session tokens enabling attackers to navigate a site as the victim in the context of the web application. In this episode the hosts Beau Bullock (@dafthack) & Mike Felch (@ustayready) demonstrate how to exploit a XSS vulnerability to access HTML5 local...
After getting a shell on a server you may or may not have root access. To gain privileged access to a Linux system it may take performing more analysis of the system to find escalation issues. In this episode of Tradecraft Security Weekly Beau Bullock (@dafthack) provides a methodology for performing various privilege escalation techniques against Linux-based systems.

In this episode of Tradecraft Security Weekly, Mike Felch discusses with Beau Bullock about the possibilities of using framesets in MS Office documents to send Windows password hashes remotely across the Internet. This technique has the ability to bypass many common security controls so add it to your red team toolboxes.

Google provides the ability to automatically add events to a calendar directly from emails received by Gmail. This provides a unique situation for phishing attempts as most users haven't been trained to watch their calendar events for social engineering attempts. In this episode Beau Bullock (@dafthack) and Michael Felch (@ustayready) show how to inject events into a targets calendar using MailSniper bypassing some security control...
When pentesting web services or an application that leverage XML files, XML External Entity (XXE) attacks are a great way to start. By injecting an XXE into a well crafted XML payload before it's sent to the server, a penetration tester can trick the parser into executing other actions that the developer never intended. This can lead to reading local files, server-side request forgeries (SSRF) or even gaining remote code execution ...
Domain fronting is a technique used to mask command and control (C2) traffic. It is possible for C2 channels to be proxied through CDN's like Cloudfront to make it appear like normal Internet traffic. It is very difficult to detect and block for defenders as it appears as if clients on a network are connecting to valid CDN domains. But, in reality it is transporting a command and control channel. In this episode of Tradecraft Secur...
If you are a penetration tester password cracking is something you will inevitably do. On most engagements we typically don't have months on end to crack passwords. In an effort to help be more efficient in your cracking techniques Beau Bullock (@dafthack) describes various ways to streamline your approach to cracking in episode 17 of Tradecraft Security Weekly.

There are a ton of modules in Metasploit that are extremely useful for performing various attacks post-exploitation. But sometimes there are external tools that you might want to use that are not included in Metasploit. It's possible to proxy other external tools through a Meterpreter session using a module in Metasploit and proxychains. In this episode Derek Banks (@0xderuke) and Beau Bullock (@dafthack) talk about how to pivot ex...
Session management in web applications is extremely important in regards to securing user credentials and integrity within the application. Sometimes session tokens can be predicted provided the overall randomness is weak. If this is possible a remote attacker may be able to compromise the session of an authenticated user. In this episode of Tradecraft Security Weekly both Beau Bullock (@dafthack) and Mike Felch (@ustayready) discu...
A very common attack that many networks are vulnerable to is called LLMNR or NBT-NS poisoning. Through this attack it is possible to gain access to a user's NTLMv1 or v2 password hash. A more interesting attack can be carried out under the same premise though. Instead of just obtaining a password hash the user's authenticated session to another host can be exploited to run arbitrary code on the server. In this episode of Tradecraft...
There were a lot of amazing new tools and techniques released at Hacker Summer Camp 2017. In this week's episode of Tradecraft Security Weekly Beau Bullock (@dafthack) talks about some of the more interesting items he saw at the Black Hat and DEF CON conferences.

On penetration tests we are often-times faced with very large external or internal attack surfaces that are made up of multiple web applications. When there is a need to assess thousands of webapps quickly manually navigating each page with a browser would be very inefficient. In this episode of Tradecraft Security Weekly Beau Bullock (@dafthack) details how to automatically screenshot multiple web applications for quick analysis.
Email tends to be the primary communication platform for employees of an organization. Often times sensitive data is transmitted from one internal employee to another via this mechanism with no regard for security. In this episode of Tradecraft Security Weekly Beau Bullock (@dafthack) shows how to use a PowerShell-based tool called MailSniper to search through the mailboxes of employees at an organization for sensitive data.

How do you perform incident response on systems in your environment at scale or when the system that needs to be analyzed is in a geographically different location than your analysts? What if you need to do this and have no real budget to work with to use commercial tools? The answer is Google Rapid Response (Google GRR). In this Blue Team Edition Episode of Tradecraft Security Weekly we (@0xderuke & @dafthack) demonstrate retrievi...
