An abuse report is a formal notification documenting observed malicious activity originating from or targeting specific network assets. These reports contain critical forensic data including source IP addresses, domain names, timestamps, affected URLs, and categorization of the abuse type—such as phishing, malware distribution, DDoS attacks, or spam campaigns. Generated by automated monitoring systems or security analysts, abuse reports serve as actionable intelligence for identifying and mitigating cyber threats.

These documents are systematically sent to responsible entities like Internet Service Providers (ISPs), hosting providers, or domain registrars to alert them of security incidents within their infrastructure. Abuse reports empower Computer Security Incident Response Teams (CSIRTs) and Security Operations Centers (SOCs) to initiate swift investigations, remediate compromised systems, and disrupt malicious operations. By contributing detailed observations of suspicious activity, they play a fundamental role in enriching collective threat intelligence and fostering collaborative defense across the digital ecosystem.
