Brute Ratel C4 (often stylized as bruteratel) is a commercial, next-generation red teaming and adversary simulation software. It was developed to counter the growing effectiveness of Endpoint Detection and Response (EDR) and Next-Generation Antivirus (NGAV) systems.
Unlike traditional frameworks that rely on known, heavily signatured payloads, Brute Ratel focuses on living-off-the-land binaries (LOLBins), custom shellcode injection, and unique communication protocols. Its primary selling point is its ability to bypass modern security controls that easily flag tools like Cobalt Strike. brute ratel github

GitHub is a goldmine for C2 profile examples. Profiles define how the agent communicates with the server (jitter, headers, URIs). A generic profile.json might look like: "http-config":
"user-agent": "Mozilla/5
"http-config":
"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)",
"uris": ["/update.php", "/css/main.css"],
"jitter": "15"
Using unique profiles prevents your C2 traffic from being fingerprinted.
Edit the config.py file to configure Brute Ratel according to your needs:
# config.py
# Set the target URL or IP address
TARGET_URL = "https://example.com"
# Set the username or token list
USERNAME_LIST = ["user1", "user2", "user3"]
# Set the password list
PASSWORD_LIST = ["pass1", "pass2", "pass3"]
