Between May and July 2026, security researchers deployed an unauthenticated Model Context Protocol (MCP) honeypot server to observe how threat actors exploit AI agent infrastructure. Of approximately 1,000 sources that reached the decoy, 596 spoke the protocol and 24 proceeded to actively exploit it. These operators executed 628 shell commands, 255 file reads, and 248 secrets-store lookups, with 19 hunting credentials and 4 attempting container escapes. Activity escalated from 39 tool calls in May to 877 by mid-July. Three stolen credentials were subsequently used against a live AWS account, with two cases involving Bedrock model invocation for LLMjacking. The attacks demonstrated automated reconnaissance, credential harvesting, container escape attempts, backdoor account creation, and Kubernetes enumeration, revealing that exposed MCP servers represent a growing attack surface as AI agent infrastructure proliferates.

An AWS environment was targeted in a sophisticated attack, with the threat actor gaining administrative privileges in under 10 minutes. The operation showed signs of leveraging large language models for automation and decision-making. Initial access was obtained through credentials found in public S3 buckets, followed by rapid privilege escalation via Lambda function code injection. The attacker moved laterally across 19 AWS principals, abused Amazon Bedrock for LLMjacking, and launched GPU instances for potential model training. The attack involved extensive reconnaissance, data exfiltration, and attempts to establish persistence. Notable techniques included IP rotation, role chaining, and the use of AI-generated code.
