. These tools are designed to gain unauthorized access to computers by systematically trying thousands of username and password combinations.
If you are looking for information on how to use or configure this software, please be aware of the following: Cybersecurity Risks
: Using or distributing brute-forcing tools is often associated with malicious activity and can lead to severe legal consequences under computer crime laws (such as the CFAA in the US). Malware Warning
: Files labeled as "RDP Brute" or "z668" on public forums or Telegram channels are frequently "backdoored." This means the tool itself may contain a trojan designed to steal data or use your computer as part of a botnet. Ethical Alternatives
: If you are interested in security testing, I recommend exploring Penetration Testing frameworks like Metasploit within a controlled, legal environment (such as Hack The Box How to Protect Against RDP Brute Forcing
If you are trying to secure a server against these types of attacks, follow these best practices:
: Never expose RDP (Port 3389) directly to the internet. Require a VPN connection first. Enable MFA
: Use Multi-Factor Authentication (like Duo or Microsoft Authenticator) for all remote logins. Account Lockout Policies
: Configure your system to lock accounts after a small number of failed attempts. Change Default Ports

Purpose: It is designed to find potential open RDP ports and systematically guess login credentials by attempting various username and password combinations.
Architecture: The tool is reportedly written in C#, though research suggests it may utilize native DLLs or forked projects like FreeRDP for its core scanning capabilities.
Operational Role: In the threat landscape, it serves as an "initial engagement" tool. Once a foothold is established, threat actors use it for lateral movement, privilege escalation, and eventually the deployment of ransomware such as Bucbi or LockCrypt. Key Features
Credential Transformations: The tool utilizes "markers" or "transforms" in its password lists—such as %OriginalUsername% or %domain%—to dynamically generate variations of passwords based on the targeted user.
Customization: It has been observed in the wild with command-line arguments like /install and /uninstall to manage persistent services (e.g., FileService) on compromised machines.
Stealth & Logging: The tool can generate debugging statements and logs in hidden directories like %ALLUSERSPROFILE% to help attackers track their progress. Threat Actor Usage
The tool is a staple in the "cybercrime underground" and has been linked to several high-profile groups:
Truniger hacking group: Used the tool to deploy crypto-locking malware. The text "RDP Brute (Coded by z668)" refers

to run as a background service and generate hidden log files for the attacker. ⚠️ Risks & Security Implications For security professionals, the presence of on a network is a critical alert indicating an ongoing or successful breach. Ransomware Delivery
: Attackers use this tool to gain the initial foothold required to disable antivirus software and deploy crypto-locking payloads. Resource Drain
: The intensity of the automated login attempts can significantly degrade server performance. Lateral Movement
: Once one machine is cracked, the tool can be used to harvest further credentials and spread throughout the organization. How to Protect Your System
If you are reviewing this tool for defensive purposes, the following steps are essential to neutralize the threat: Enable Network Level Authentication (NLA)
: This forces users to authenticate before a full RDP session is established, making banner scraping much harder. Implement Account Lockouts
: Set a threshold (e.g., 5-10 failed attempts) to temporarily lock accounts, which effectively stops brute-force tools in their tracks. Use a VPN or Gateway
: Never expose RDP (Port 3389) directly to the public internet. Use a Remote Desktop Gateway or VPN instead. MFA is Mandatory
: Multi-factor authentication is the single most effective defense against credential-based attacks like those performed by If you'd like, I can help you: firewall rules to block common RDP scanning IPs.

Despite being an older tool, RDP brute-forcing remains a top attack vector in 2026 because many organizations still leave RDP ports (3389) exposed to the public internet. Attackers use it to establish a foothold, move laterally within a network, and eventually deploy ransomware. Fox-IT Logo How to Defend Against It
To protect your systems from "RDP Brute (Coded by z668)" and similar tools, cybersecurity experts from organizations like Palo Alto Networks recommend: Security Measures : To protect against these attacks,
How Does it Work?
- Automated Tools: Attackers use automated tools or scripts that can try thousands of login combinations per minute.
- Dictionary Attacks: These tools often use dictionary words, common passwords, and variations, including adding numbers or special characters to common words.
- Credential Stuffing: Sometimes, attackers use lists of credentials obtained from other breaches to try and gain access.
3. Safety and Legality (Zero)
This is the most critical part of the review.
- Malware Risk: Tools shared under names like "Z668" on Telegram, cracking forums, or Pastebin are frequently backdoored. There is a very high chance that while you are trying to hack a server, the tool is installing a cryptocurrency miner or information stealer on your computer.
- Legal Consequences: Using this tool against servers you do not own is illegal in almost every jurisdiction. It falls under computer misuse acts (e.g., CFAA in the US, Computer Misuse Act in the UK). Even scanning IP ranges can result in your ISP terminating your service.
