I built free decoy keys for websites. A stolen fake AWS key was used for a takeover attempt 2 hours 39 minutes later

Side project from the last few weeks. I left fake keys and files on my own sites where attackers look: .env files, AWS credentials, OpenAI keys, Cursor and Claude configs, a fake admin login, a fake MCP server. On Oct24 a scanner on a cloud server took the fake AWS key at 03:04 UTC. At 05:43 it used it: listed servers, checked whether it could send email, then tried to make itself admin. If that key had been real, the bill and the cleanup would have been mine. So I turned

AI 分析

痛点:开发者的 .env 文件与云凭证被暴露后,往往在几小时内就会被扫描器盗用,并用于提权与刷云账单,而当事人事后才发现;他们缺少低成本的早期预警和自动止损手段。

目标用户:独立开发者、小型 SaaS 团队、WordPress 站长、开源仓库维护者

证据:On Oct24 a scanner on a cloud server took the fake AWS key at 03:04 UTC. At 05:43 it used it: listed servers, checked whether it could send email, then tried to make itself admin. If that key had been real, the bill and the cleanup would have been mine.

变现:以免费用开源诱饵引流,对团队版收费:为多个站点提供统一告警(邮件、Slack)、攻击者 IP 全网联动封禁、托管扫描与合规报告;也可做按站点数的低价订阅($5–15/月)。

MVP:两周内做 npx 包与极简托管告警后端:把诱饵文件放进仓库或站点,一旦被访问就发送告警,并自动通过 Cloudflare API 或 WAF 封禁来源 IP;差异化点在于识别访问者是脚本、人还是 AI agent,并做跨站点封禁名单同步,而不是自建完整扫描器。

竞品:Thinkst Canarytokens(免费,事实标准)、GitGuardian Honeytoken、TruffleHog / gitleaks(密钥泄露扫描)、AWS GuardDuty 凭证泄露检测

摘要:作者在自己站点布置假 AWS/OpenAI 密钥、假 MCP server 等诱饵,10月24日一枚假 AWS key 在 03:04 UTC 被云上扫描器取走,05:43 就被用于列服务器、试探发信与自我提权;若为真钥,账单与善后都由他承担。他把这套方案做成开源免费的 AgentDecoy(npx、WordPress 插件、单 PHP 文件),并支持多站点联动封禁被盗密钥来源 IP。项目完全免费且无任何付费意愿或收入数据,刚发布即寻求反馈,变现路径尚待验证。
