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 is a tool that allows pentesters to spin up multiple servers to proxy attempts through to bypass some of these detection mechanisms.

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.

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 storage to steal a cookie.

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 controls that Google has in place.

Domain Fronting - Tradecraft Security Weekly #18 15:33

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 Security Weekly Beau Bullock (@dafthack) is joined by Ralph May (@ralphte1) to talk about what domain fronting is and how to set it up using Cloudfront and PowerShell Empire.

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.

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.

After exploiting a system on a remote & unfamiliar network it is extremely important to gain situational awareness as quickly, and quietly as possible. This will help ensure success moving forward with other attacks. In this episode of Tradecraft Security Weekly Beau Bullock (@dafthack) will show how to use PowerShell to query information about the current computer, user, and domain to avoid running built-in commands like 'net', 'ipconfig', or 'netstat'.

Meterpreter with Categorized Domains & Trusted Certs - Tradecraft Security Weekly #4 12:06

It is common for organizations to proxy web traffic so they can place restrictions on what websites can be visited by employees. To make the management of allowing or denying access to a large number of sites easier many web proxies utilize categorization engines to group sites into various subjects. Uncategorized sites are generally blocked. In this episode I show how it's easy to locate recently expired domains that have been categorized already, and can be utilized to get past web proxy filters. Additionally, I show how easy it is to set up a trusted certificate on the payload handler to encrypt the session using a custom cert.

Microsoft Exchange and Office365 are extremely popular products that organizations use for enterprise email. These services can be exploited by remote attackers to potentially gain access to Active Directory user credentials. In this Tradecraft Security Weekly episode Beau Bullock (@dafthack) demonstrates how to utilize MailSniper to enumerate internal domains, enumerate usernames, perform password spraying attacks, and get the global address list from Exchange and Office365 portals.

Public File Metadata Analysis with PowerMeta - It is very common for organizations to post files (docx, pdf, xlsx, etc.) to publicly available websites on the Internet. Often times these organizations have not taken the time to strip the metadata attached to these files. This leaves the potential for remote attackers to discover sensitive information from them including usernames, software used to create them, or system names. In this episode Beau demonstrates a PowerShell tool called PowerMeta that can be used to discover these files on a target site and extract the metadata from them.
