Arctic Wolf says the agentic tool planted web shells, ran OS commands, and exposed secrets and S3 data.

Dark Reading reports that Artex, an agentic penetration-testing tool released as open source in August by a Chinese developer and delisted on October 8, continues through variants. Arctic Wolf Labs says attackers recently used AntiFox against internet-facing web services and AWS, breaching Microsoft IIS servers, deploying web shells, running OS commands, enumerating services, exposing production secrets, and manipulating S3 buckets. Defenders quoted say defense is mostly a matter of willingness; the article's mitigation advice is cut off.

Unconfirmed: The eight-vulnerability result is one vendor benchmark, and the article does not name the flaws AntiFox exploited.

Key facts
  • A Security says its benchmark run found eight vulnerabilities in about 45 minutes.
  • The original Artex listing was removed on October 8, but variants remain.
  • AntiFox activity described includes IIS web shells and AWS S3 manipulation.
  • No named CVE or fixed product version is given.
