malc0de (malc0de.com) is a long-standing, free malware URL and malicious domain database. It primarily tracks websites hosting malware (drive-by download pages, exploit kits, malware payloads). It’s maintained by a single researcher (often referred to as unknown or Mike), with updates dating back to 2008.

The malc0de database is a relic of an older internet—a time when drive-by downloads were the primary infection vector and security researchers shared raw URLs on Pastebin and private IRC channels. If you are building a modern SOC (Security Operations Center), you should prioritize feeds from AlienVault OTX, MISP (Malware Information Sharing Platform), or URLhaus.
However, for the tinkerer, the legacy system administrator, or the threat historian, Malc0de represents a golden era of OSINT. It proves that cybersecurity does not always require a six-figure budget. Sometimes, a simple list of malicious URLs, diligently maintained, can block a zero-day exploit kit before your commercial antivirus even releases a signature.

Final Recommendation: Use Malc0de as a secondary, free layer of defense. Combine it with DNS sinkholing and strict browser security policies. Do not let its outdated interface fool you; the data, when available, is still live malicious infrastructure. Always verify before blocking, and always analyze in a sandboxed environment.
Disclaimer: URLs, IP addresses, and the status of the Malc0de database change constantly. Always verify the current status of the service at the official domain and practice safe browsing habits when handling threat intelligence feeds. Navigate to malc0de
Here’s a proper, structured review of the malc0de database based on its known features, utility, and limitations in the cybersecurity community.
For over a decade, the Malc0de RSS feed has been a cornerstone for free automation. Security engineers could write Python or Bash scripts to poll the feed every hour and automatically update blocklists on their SIEM (Security Information and Event Management), IDS/IPS (Intrusion Detection/Prevention System), or DNS sinkhole.
