Orcus is a RAT that is used to access or have control of computers remotely. These tools can be legitimately used by anyone but are mostly used by criminals for malicious reasons. Most of the time they trick s to install these programs and then use them to different information in order to generate revenue. We bring you Orcus RAT to try it using the official code, all for free on Windows 10/11 or Mac.
You will be amazed to know that it carries features similar to TeamViewer and other software. Moreover, it has some features which are not legal like:
- Disable webcam activity light.
- Open microphone remotely.
- Get codes from apps that are popular.
- Get browser cookies.
What is Orcus RAT
It records sound using the microphone, performs keylogging and much more. Keep in mind that such features are not included in its basic version and can be bought at $40.
It is being promoted on the hacking forum on which s are able to buy and sell malicious programs, hacks, exploits and other stuff. Research indicates that security thefts use spam campaigns like emails to trick people to install this specific tool. This is why DarkComet RAT was also popular because it was very stealthy.
Now what they do is send in emails that are presented as messages from “Lathe and CNC Machines” as invoices. Such emails carry attachments that when opened and install. These campaigns are common means to proliferate system infections or legitimate tools like RAT which are then used in malicious ways.
How does Orcus RAT works
If this gets installed on the system then it can:
- Steal s, sensitive data and s of the .
Certain plug-ins can files including ransomware. If one is tricked into installing this then it results in:
- Privacy issues.
- Financial losses.
- PC infections.
Sometimes it is also disguised as another app running in the background system.
Many of these can be found of the internet. A few examples are Imminent Monitor, Agent Tesla, CrimsonRAT, and H-Worm. Security thefts can use these tools for malicious reasons. If RAT is present on the system and is not installed intentionally, it can be immediately removed.

How Orcus RAT Infects Victims PC
Computer infections are caused by spam campaigns. Emails with files attached are sent to them which are mostly Microsoft Office Documents, Java Scripts files, Executables (.exe files), PDF docs and archives like ZIP, RAR and much more.
Once they are opened, they and install malicious programs. Other ways include unofficial or fake s, Trojans, software which is not trustworthy and software cracking tools. Trojans are malicious programs that can and get programs of such kinds.
The following are used to proliferate malicious programs:
- Freeware .
- Free file-hosting sites.
- Peer-to-peer networks like torrent clients, e-mail and other such programs.
- Unofficial pages and other dubious software channels.
Security thefts present infected files as normal, legitimate and harmless however once they get ed and opened install malware. s usually use software cracking tools to by paid activation of installed software or OS. However, such tools can proliferate system infections.
Now despite activating programs, they usually and install malicious programs.
It carries a certain standard but a robust feature set for technologically advanced RAT. It can:
- Get screenshots.
- Record input.
- Activate the webcam.
- Steal codes.
- Record audio.
- Steal information.
Moreover, it can detect it is being launched on a virtual machine in order to complicate analysis by researchers.
It carries functions that make it capable. It also has certain functions, like ing plug-ins. Besides, offering the ability to build them, it carries a complete library or plug-ins that have been created from which attackers can select. Moreover, these can be written in languages like C#, C++ and VB net.
Creators of malware made a dedicated development program to make extension development more streamlined. Those who do not have enough skills to build plug-ins from scratch take help from tutorials and get benefits from document libraries.
It also carries a GitHub page where samples of created plug-ins are published by the authors.
Another feature is that malware that has been packed into this virus is real-time scripting, allowing it to write and run code on machines it has caused an infection on.
John Revesz developed the virus is also known as Armada. Back in 2019, it got accused by Canadian authorities of operating an international malware distribution scheme.
Revesz in his defense claimed that it is a legitimate program for remote istration and his company, Orcus Technologies is a legal business. However, when its functions were examined it was revealed that it is meant for malicious use cases and resulted in the author’s arrest.
He was not working alone therefore the t development theory makes sense especially when we consider the tech complexity of certain aspects of this. It carries different components, with the control being separate. Moreover, the server established by malware connects after infection and does not hold any . This benefits attackers in many ways such as sharing access to infected systems from the same server and allowing greater scalability or infected networks.
How To Use Orcus RAT
This is a straightforward process. It mostly disguises itself as cheat code or cracks; therefore, it is delivered to a system as an archive file with the compressed executable file within. As it is written down in C# it at times uses .NET infrastructure present in Windows, now to complete the C# source code our sample started visual C# complier which began resource file to COFF object conversation utility.
Once this was compiled, the executable file started its execution and malicious activity. Keep in mind that this tool does not all the time make its way into the system that has been infected. In certain cases, it comes as a pre-compiled executable file that requires a to double-hit on it, to begin with, the execution.
It makes its way into the target machine as a able attachment in spam emails. The campaigns usually target organizations rather than individuals.
Attackers use phishing and social engineering to trick people into ing an attachment or visiting a link that points toward a server that holds a payload. To start with execution it needs input. However, in many cases, it cannot infect the system without interaction.
Note: The Orcus website was shut down because of legal issues however it may still be available on the Wayback Machine. If you can you can buy it? No, and any sites with such claims are fraudulent.

Orcus RAT Free – #1 Remote Access Trojan
This Remote tool has not been around for a long time and only recently came into development. The best part is that Orcus RAT free is open source and the code is available online on GitHub to access and analyze. The founder of this project was arrested however the code and files are available for educational and informational purposes only. You are responsible for any damage you do to it.
Caution: It does work on Mac but may crash various times.
