Could you build this?
No This is offensive cybersecurity research demonstrating 0-click remote code execution via multi-stage prompt injection, requiring deep penetration testing expertise.
What it would actually take: Building these exploits involves analyzing agent execution loops, reverse-engineering tool sandboxes, and crafting complex payload encoding chains (such as base64/base85) to bypass multi-layer system guardrails. The core hurdle is offensive security methodology and low-level sandbox escape analysis rather than application programming. Executing this work demands seasoned application security researchers and penetration testers.
Discussion
2 comments analyzed.
Competitors mentioned: hackmyclaw.com
Concerns raised: Challenge setup is a black box with unknown user intent, making realistic prompt injection testing difficult, Batch processing of emails every 3 hours may bias model behavior and introduce detection artifacts, Lack of disclosed information about version, config, and setup reduces realism, Email-only injection vector is limiting, False security claims based on unsolved challenges rather than actual security
Feature requests: Disclose setup details including version, user intent, and exact configuration, Provide access to fresh context for each experiment, Allow multiple injection vectors beyond email
