Malc0de Database ((link)) Site
Malc0de database is a well-known repository of malicious URLs and IP addresses, though many automated tools (like
) have noted its offline or deprecated status in recent years. If you are looking to create a
for a security tool or research project using this data, you should focus on extracting specific indicators of compromise (IoCs). Key Features from Malc0de
A standard feature for a malware detection engine or SIEM using Malc0de would typically include the following data points: Malicious Domain malc0de database
: The specific URL or hostname identified as serving malware. IP Address : The server IP hosting the malicious content. CC (Country Code) : The geographical origin of the hosting server. ASN & Autonomous System Name
: Data to identify the network provider responsible for the IP. : Often used to pivot to a VirusTotal report for further analysis of the payload. Implementation Idea: Real-time Blocklist Sync
If you're building a feature for a firewall or network monitor (like Automated Fetching : Set up a script to pull from the Malc0de IP Blacklist periodically. Normalization : Parse the text file to extract clean IP/Domain strings. Threat Mapping Malc0de database is a well-known repository of malicious
: Use the ASN and Country Code data to visualize where the highest density of threats is originating from in your specific network traffic. Python script

Research use cases
- Measuring exploit-kit activity over time by tracking landing page families.
- Studying domain churn and patterns in typosquatting or domain-shadowing abuse.
- Correlating URL-based campaigns with malware families via payload hash matches.
- Analyzing referrer patterns to identify compromised advertising networks or distribution chains.
Third-Party Aggregation
Major threat intelligence aggregators (such as AlienVault OTX and MISP) often referenced Malc0de data as a primary source for their own composite intelligence reports. Research use cases
What is the Malc0de Database?
At its core, Malc0de (pronounced "Mal-code") is a free, web-based database dedicated to tracking and listing URLs that host malicious software (malware). Unlike aggregated search engines that rely on multiple antivirus engines, Malc0de traditionally focused on a specific niche: drive-by download websites and exploit kits.
Launched in the late 2000s, during the golden age of exploit kits like Blackhole, Nuclear, and Fiesta, Malc0de served as a community-driven watchlist. When a security researcher discovered a live URL serving a malicious payload, they would submit it to Malc0de. The system would then verify the threat and make the data available to the public via a simple web interface and a structured RSS feed.
