The industry standard for sharing network abuse reports

XARF – eXtended Abuse Reporting Format

To stop attacks or take down illegal content, informing the owner or maintainer of the source is the only way to mitigate issues and therefore is an essential part of the internet infrastructure.

What is it?

Initially started as an open, community-driven effort, XARF is now the industry standard for sharing network abuse reports that provides free specifications to aid in the automated expressions of information about network abuse observed.

The need for a standard

Attacks on network infrastructure, trademark, or copyright infringements; dangerous content, like phishing or hosted malware or illegal content, like child exploitation material, all have an origin or a source.

Informing the owner or maintainer of the source, to stop the attacks or take down the content in question is the only way to mitigate these issues, and therefore is an essential part of the internet infrastructure.

Unfortunately, the status quo for reporting abuse is a very unstructured and cluttered environment, which is the primary reason for the lack of efficiency in operationalizing abuse report metadata today.

Community effort

XARF is a standard developed to improve the ability of recipients of abuse reports to operationalize the data. Unlike previous methods of sharing network abuse data, X-ARF is simple, extensible, and structured, and, therefore, easily automated.

XARF aims to improve security measures in a few ways:

  • Extend the capabilities of current network abuse report sharing
  • Add the flexibility to adapt to new use cases as they occur quickly
  • Easy to generate
  • Easy to read (machine- as well as human-readable)
  • Provide the basis for a unified and holistic approach to abuse handling

XARF is an open, community-driven effort that provides free specifications to aid in the automated expression of information about network abuse observed.

Use Cases

XARF schemas conform to a wide range of pre-existing report types, so that the receiving network operator may easily automate and consume the format. Field naming in one schema maps to other schemas making scaling easier, allowing the network operator to act on vulnerabilities, abuse, and fraud with higher speed.
