A typical entry in the Malc0de database is a study in minimalism:
2010-10-08 20:38:58 | http :// 190.112.154.227 / dark / start.exe | 190.112.154.227
That’s it. No YARA rules. No MITRE ATT&CK mapping. No CVSS scores. Just a timestamp, a malicious URL, and an IP address.
For a junior analyst, this looks useless. For a veteran, it’s gold. The URL structure tells a story: the dark directory, the start.exe binary—these are hallmarks of a specific ZeuS or SpyEye variant from the early 2010s. The raw IP address bypasses DNS trickery, allowing an analyst to block traffic at the network layer.
One of the most valuable aspects of Malc0de is its emphasis on live URLs. Many threat intelligence lists suffer from "list rot"—indicators that were malicious six months ago but are now benign or defunct. Malc0de frequently purges dead links, ensuring that security professionals are not wasting firewall rules on inert IP addresses. malc0de database
The malc0de database (stylized as malc0de) is a free, publicly accessible repository that tracks malicious URLs and domains used to distribute malware. Unlike search engines that index the entire web, malc0de specifically focuses on drive-by download sources—websites that automatically download malware to a visitor's computer without their consent or knowledge.
Founded by a security researcher known as "Kafeine" (formerly of Proofpoint), malc0de gained traction between 2010 and 2018 as a go-to resource for tracking Exploit Kits (EKs) such as Angler, Nuclear, and RIG. Today, while the landscape has shifted toward document macros and PowerShell scripts, the database continues to log live malicious payloads.

The Malc0de Database is a long-running, community-driven repository that aggregates and indexes URLs, IPs, and samples associated with malicious software (malware), drive-by downloads, phishing pages, and other web-based threats. It was widely referenced by security analysts, incident responders, and researchers for historical lookup of malicious domains and campaigns. The database collected indicators of compromise (IOCs) such as malicious URLs, download links, and associated metadata (timestamps, referrers, payload hashes) to help detect and analyze web-borne threats.
The cybersecurity world has changed dramatically. In 2015, 80% of malware came from web exploits. Today, 70% comes from email phishing (according to Verizon DBIR). Has the malc0de database become obsolete?
Not entirely, but it has pivoted.
Modern malc0de entries now focus on:
Furthermore, the database now tracks Malicious IP addresses more aggressively. As malicious actors shift to bulletproof hosting on compromised cloud servers (AWS, DigitalOcean), malc0de tracks the IP rotation patterns.
