It features a few tools:. We have used this tool as part of an RDP honeypot which records sessions and saves a copy of the malware dropped on our target machine.
PyRDP was first introduced in a blogpost in which we demonstrated that we can catch a real threat actor in action. In May a presentation by its authors was given at NorthSec and two demos were performed.
The first one covered credential logging, clipboard stealing, client-side file browsing and a session take-over. The second one covered the execution of cmd or powershell payloads when a client successfully authenticates. This tool has been tested to work on Python 3. It has not been tested on OSX. First, make sure to install the prerequisite packages on Ubuntu :.
You will make a mess, and using a directory name like venv is more standard anyway. Before installing the dependencies, you need to activate your virtual environment:. This should install all the dependencies required to run PyRDP. If you ever want to leave your virtual environment, you can simply deactivate it:.
Note that you will have to activate your environment every time you want to have the PyRDP scripts available as shell commands. Installing on Windows The steps are almost the same. There are two additional prerequisites.
To store the PyRDP output permanently logs, files, etc. For example:. Make sure that your destination directory is owned by a user with a UID ofotherwise you will get a permission denied error. This redirects the GUI of the player to the host screen. To do so, add the -e and —net options to the run command:.
If you plan on using the player, X11 forwarding using an SSH connection would be a more secure way. If you get this error, it means that you are using the module pycrypto instead of pycryptodome. Assuming you have an RDP server running on These are used when TLS security is used on a connection.
Note: the port argument is optional, the default port is Once this is done, you pass Running payloads on new connections PyRDP has support for running console commands or PowerShell payloads automatically when new connections are made. Here is how it works:. You must give it an amount of time to wait for before running the payload.
After this amount of time has passed, it will send the fake key sequences and expect the payload to run properly. To do this, you use the --payload-delay argument. The delay is in milliseconds. For example, if you expect the user to be logged in within the first 5 seconds, you would use the following arguments:. We recommend you set this to the maximum amount of time you would expect the console that is running your payload to be visible. In other words, the amount of time you would expect your payload to complete.A Microsoft Windows component, RDP was designed to provide administrators, engineers, and users with remote access to systems.
However, threat actors have been using the technology for nefarious purposes, and the trend continues, especially since an RDP attack is usually more difficult to detect than a backdoor.
Not only RDP is the perfect tool for accessing compromised systems externallybut RDP sessions can also be daisy chained across multiple systems as a way to move laterally through an environment. FireEye has observed threat actors using the native Windows Network Shell netsh command to utilize RDP port forwarding as a way to access newly discovered segmented networks reachable only through an administrative jump box. If RDP is enabled, threat actors have a way to move laterally and maintain presence in the environment through tunneling or port forwarding.
To mitigate vulnerability to and detect these types of RDP attacks, organizations should focus on both host-based and network-based prevention and detection mechanisms.

AWS's policy regarding the use of security assessment tools and services allows significant flexibility for performing security assessments of your AWS assets while protecting other AWS customers and ensuring quality-of-service across AWS. The term "security assessment" refers to all activity engaged in for the purposes of determining the efficacy or existence of security controls amongst your AWS assets, e.
Prohibited activities include, but may not be limited to:.
A security tool that solely performs a remote query of your AWS asset to determine a software name and version, such as "banner grabbing," for the purpose of comparison to a list of versions known to be vulnerable to DoS, is NOT in violation of this policy.
Additionally, a security tool or service that solely crashes a running process on your AWS asset, temporary or otherwise, as necessary for remote or local exploitation as part of the security assessment, is NOT in violation of this policy. However, this tool may NOT engage in protocol flooding or resource request flooding, as mentioned above. A security tool or service that creates, determines the existence of, or demonstrates a DoS condition in ANY other manner, actual or simulated, is expressly forbidden.Attacking RDP with Seth
It is the sole responsibility of the AWS customer to: 1 ensure the tools and services employed for performing a security assessment are properly configured and successfully operate in a manner that does not perform DoS attacks or simulations of such, and 2 independently validate that the tool or service employed does not perform DoS attacks, or simulations of such, PRIOR to security assessment of any AWS assets.
This AWS customer responsibility includes ensuring contracted third-parties perform security assessments in a manner that does not violate this policy. Furthermore, you are responsible for any damages to AWS or other AWS customers that are caused by your Testing or security assessment activities.
Prohibited activities include, but may not be limited to: Protocol flooding e. Have Questions? Contact Us. Exploring security roles? Want AWS Security updates?I also get that error! How to find someones external ip adress and is it possible finding it on facebook. The easiest way is via email header. Finding IP via skype is pretty easy too. There is no direct method as such for Facebook that I'm aware of. Please elaborate. There is no redirect mechanism per se on this website. Any details would be appreciated.
Setting up USB wireless adapter? I don't get it. That'll be it. Hi A emergency questions: i 'm not found answer in internet and youtube :: please note :i have compete complete full access to the victim ADSL rouer web interface. I can't think of a simple way for the attacker to enable RDP if it's not running that sort of change requires administrator privileges, and if we had that in first place the crash exploit would be a joke.
Also, I think tracing IP won't be hard. Depending on the method of attack, even a wireshark capture can give the victim your IP. I'm not into forensics at all, but if you make no efforts to hide your ass, it won't take the victim much efforts to find you ass :p. I have no idea how easily if at all the victim can find you once you've removed the payload, i. Checking RDP status Hi are using Wordpress for your site platform?

Great article Lot's of information to Read Great Man Keep Posting and update to People. Thanks curved monitor gaming.
Such a very useful article. Very interesting to read this article. I would like to thank you for the efforts you had made for writing this awesome article. Great tips and very easy to understand. This will definitely be very useful for me when I get a chance to start my blog. Crashing Windows 7.Awesome post Seth! Thanks a lot! Thanks Jarvis. Once I finish up that post, I can finally get to the good stuff. All the cool things you can test once you have your own AD playground! This is exactly what I was looking for!
I was about to set up an on premise lab, but using AWS will be so much easier! After this, I may still set up on premise so I can expand.
Thanks for the comment Jimmy. Good luck and let me know if there is anything i should add to this post for others. At some point in the future I'm going to investigate exactly how much you can save by taking snapshots and storing them on s3, in the event you know you are not using the lab for a few months. It still costs money, but less money for sure. Another option I want to investigate would be to use some of the automation functionality within AWS to completely build a lab without any interaction.
Then you can just terminate and rebuild a few months later when you need it again. Awesome post Seth. I did have a question that wasn't covered in your write-up.
Are you attacking from AWS Kali machine? If so did you have to request permission through AWS to conduct any testing on the instances you are using?
Passing the Hash with Remote Desktop
Anonymous - Yes. From what I have observed, you can do what you want inside your VPC without issue. You need to notify AWS if you are going to attack your instances from something outside your VPC though, like your home network. For this, there is a penetration testing request form. For this, AWS calls this "simulated events", and if you need that one, reach out to me via email -- I can send you the email address. Hope that helps.
Post a Comment. In this post, I'm going to walk through the process o This post covers building your lab on AWS. Even if you have a lab at home, setting up a small second home lab on AWS is a worthwhile exercise. You'll learn a lot about AWS in the process. At the end of this post, you will have a fully functional AD environment in AWS that you can use to make yourself a better penetration tester.
I'm not going to assume you are familiar with AWS or setting up Active Directory, so some of this might be review. You will create a Windows domain, promote one server to be a DC, and add additional hosts to the domain:. To get started, you really only need a Domain Controller and a Workstation. To be able to test out more stuff, you'll probably end up wanting at least two workstations User 1's workstation and User 2's workstationand at least one more non DC server.
Time to configure your security group. If you are unfamiliar with security groups, but familiar with traditional firewalls, think about it like this: A security group is like a firewall rule and you apply as many rules as you want to each AWS instance.
The combination of applied rules is kind of like your per instance firewall policy. The cool thing is that if this changes, you can just log into the AWS console from anywhere and change the IP in the security group. If you have, you know what to do here.Remote Desktop Protocol RDP is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection.
The user employs RDP client software for this purpose, while the other computer must run RDP server software from here. Default port: Be careful, you could lock accounts. You can launch a new cmd to wich new credentials will be attached so, every interaction this new shell makes with the network will use the new credentials:.
With Administrator rights you can access any opened RDP session by any user without need to know the password of the owner. Get openned sessions:. Access to the selected session. Now you will be inside the selected RDP session and you will have impersonate a user using only Windows tools and features. Important : When you access an active RDP sessions you will kickoff the user that was using it. You could get passwords from the process dumping it, but this method is much faster and led you interact with the virtual desktops of the user passwords in notepad without been saved in disk, other RDP sessions opened in other machines You could also use mimikatz to do this:.
Combining this technique with stickykeys or utilman you will be able to access a administrative CMD and any RDP session anytime. Pentesting Methodology. Tunneling and Port Forwarding.

One set of such tools belongs to the Pass-the-Hash toolkit, which includes favorites such as pth-winexe among others, already packaged in Kali Linux.
An example of easy command line access using pth-winexe is shown below. We constantly strive to include new, useful tools to our repositories. Sometimes we feel that some of these tools do not get the attention they deserve and go under-reported. One such recent addition is the version of FreeRDP, which allows a penetration tester to use a password hash instead of a plain text password for authentication to the remote desktop service in Windows R2 and Windows 8. Although in most cases that is enough, sometimes GUI access is just a better way to accomplish things.
Inadvertently however, this new security feature actually enabled the use of a password hash for RDP authentication purposes, thereby giving many pentesters once again a reason to smile. To enjoy this new feature, simply install freerdp-x RDP sessions using harvested password hashes. Again, keep in mind that this only works on Windows R2 and Windows 8.
