Arctic Wolf links AntiFox AI pentest tool to intrusions that read an AWS production secret

See how this story connects

Arctic Wolf Labs reported on 10 November that self-hosted instances of AntiFox, an open source Chinese-language agentic penetration testing platform, were linked to intrusions that used valid IAM users and an assumed EC2 role to enumerate dozens of AWS services and reach a production secret through GetSecretValue. In one intrusion the source cycled through multiple AWS identities and sent hundreds of cross-service API requests in about half an hour, and a separate case used a valid AWS identity for S3 object reads, copies and deletes. Arctic Wolf also reports an IIS compromise in which w3wp.exe created an ASPX web shell and ran commands that read web.config connection strings.

Why it matters

Arctic Wolf advises organisations running internet-facing web applications or AWS workloads to rotate exposed credentials, enforce IMDSv2 and limit broad listing permissions, because agentic frameworks increase the speed and consistency of these attacks.
