![]() ![]() ![]() Choose to use a proxy when you need a quick, reliable proxy-backed web connection, or use VPN when you require maximum security. Subscribers can access all of NetShade's fast, secure proxy and VPN servers around the world. Optional VPN enables strong encryption of all your network traffic, to secure your activity from prying eyes on the network. It also helps protect your privacy and anonymity by masking your IP address from the sites you visit. Using VPN and proxy servers allows you to access overseas web content while traveling. NetShade has been a trusted service provider since 2004. Visit websites from different parts of the world, and protect your privacy online. Route your Internet connection through another server to change your IP address. Access the world's content through some of the best VPN and proxy servers available. If we wanted to avoid RDP another option could be to check if WinRM is enabled.This app is a VPN and proxy client for the NetShade service. We’ve gained valid user credentials and have “stealthily” RDP’d onto CALVIN’s machine. In reality the \SUPERSTITIONS\share\accounts.txt file was opened remotely from CALVIN’s machine. One message in particular seems to stand out…ĭo you see anything juicy in this message? The contents of the text file is being read by the buffer, including precious credentials. Using a simple string in the “Find Message” text box as Summary contains accounts.txt we can investigate each message, checking for the buffer value… It seems this file is being opened and written to. Diving into the functionalities and filtering options is out of scope for this blog post, but after a quick superficial glance, SMB2 is observed as a Module being ran.ĭiving deeper into these SMB traces, a new source IP is found along with a file named accounts.txt. MS Message Analyzer has some nifty bells and whistles, including filter capabilities. Another option is to use logman.exe, or convert the etl to pcap for wireshark. I’m new to drilling down into ETL files, and found the simplest way to investigate is through Microsoft’s Message Analyzer tool. To end the packet capture, execute netsh trace stop We are capturing on the local IIS box, and outputting as an ETL file to C:\Users\Public\file2.etl. C:\>netsh.exe trace start capture=yes filemode=append persistent=yes \ I didn’t have any luck capturing activity on a remote share, so in this case we’ll start out capturing local packets, outputting to an ETL file. This built-in binary provides significant capabilities to interact with the network, including packet capture locally or on remote file shares. One alternative option would be to capture packets on the local share using Netsh. In this example we will avoid digging around in the share, opening any files we don’t have permissions to. ![]() You’re on a webserver owned by ACME and you start poking around and find a locally hosted file share - \SUPERSTITIONS\share. Again, these examples are simply showcasing what you can accomplish by Living Off the Land. For simplicity we’ll assume we have a secure RDP connection to the IIS server. From here, you wish to pivot onto the ACME CEO’s machine CALVIN. You’ve gained access to a public facing IIS server with Domain credentials ran by ACME. These LOLBin examples will be focused on persistence at a beginner/intermediate level. PowerShell can accomplish most of the scenario objectives, but I’ll avoid this route as it’s already heavily documented and seems to be more commonly targeted by defensive countermeasures. The primary goal of this post is to show off the capabilities of LOLBins vs the practicality of the scenario. This approach sparked my interested, so I decided to map out a lab scenario. A great blog showcasing LOLBins – Hexacorn.Talk on LOLBins with some great examples - Derb圜on2018 presentation.Solid intro into this approach – Derb圜on2013 presentation.First, I’d highly recommend to checkout a few sources first. Avoiding detection is a constant battle, so what’s the harm in using trusted built in tools?Īlthough some binaries have little documentation and take a bit of massaging to work with, there are plenty of benefits, from application white listing to remote file retrieval. Windows/UNIX - Domains/Subnets - Initial/Post/Lateral - Low Cost VPN Ranges - With Windows BinariesĪ naturally-aspirated approach focusing on the use of native built-in binaries to exploit and persist on target systems. ![]()
