  • •Anubis is causing server downtime due to its anti-scraping measures.
  • •The tool uses a Proof-of-Work scheme to deter scraping by AI companies.
  • •Users are advised to disable plugins that interfere with Anubis functionality.

Anubis, a tool designed to protect websites from aggressive scraping by AI companies, has caused significant server downtime. Users are unable to access certain resources as the server may be overloaded. Anubis employs a Proof-of-Work scheme similar to Hashcash to deter mass scraping, which adds additional load to the server. The tool requires modern JavaScript features, which may be disabled by certain plugins like JShelter. This situation is currently affecting users trying to access the lore.kernel.org website. No specific vulnerabilities or exploits have been reported in relation to Anubis itself, and the issue appears to be related to server load rather than a security breach.
