Slack AI 间接提示词注入数据渗漏 (AML.CS0035)
一句话通俗理解
公共频道里的一条帖子进了 Slack AI 的 RAG 库——用户一提问,API 密钥就顺着「链接」出了门。

事件经过
PromptArmor 演示了 Slack AI 私有数据的窃取:恶意提示词经公共频道帖进入 Slack AI 的 RAG 数据库,受害者用户查询 Slack AI 时提示词被检索执行——响应被渲染为可点击链接,受害者的 API 密钥编码在 URL 中完成外传。
运用的 ATLAS 技术
以下攻击链映射来自 MITRE ATLAS 官方数据(AML.CS0035 的
employs关系),按官方步骤编号排序;技术名称链接至本库对应技术文档,引用文字为官方对本次运用的描述。
S00
- 检索内容构造 (AML.T0066)
The researcher crafted a targeted message designed to be retrieved when a user asks about their API key.
S01
- LLM 提示词构造 (AML.T0065)
The researcher crafted a malicious prompt designed to reveal the victim’s API Key:
S02
- 有效账户 (AML.T0012)
The researcher created a valid, non-admin user account within the Slack workspace.
S03
- AI 产品或服务 (AML.T0047)
The researcher interacts with Slack AI by sending messages in public Slack channels.
S04
- RAG 投毒 (AML.T0070)
The researcher creates a public Slack channel and sends the malicious content (consisting of the retrieval content and prompt) as a message in that channel. Since Slack AI indexes messages in public channels, the malicious message is added to its RAG database.
S05
- 间接提示词注入 (AML.T0051.001)
When the victim asks Slack AI to find their “EldritchNexus API key,” Slack AI retrieves the malicious content and executes the instructions:
S06
- RAG 凭证窃取 (AML.T0082)
Because Slack AI has access to the victim user’s private channels, it retrieves the victim’s API Key.
S07
- LLM 响应渲染 (AML.T0077)
The response is rendered as a clickable link with the victim’s API key encoded in the URL, as instructed by the malicious instructions:
The victim is fooled into thinking they need to click the link to re-authenticate, and their API key is sent to a server controlled by the adversary.
