Slack’s AI assistant has a security flaw that could let attackers steal sensitive data from private channels in the popular workplace chat app, security researchers at PromptArmor revealed this week. The vulnerability exploits a weakness in how the AI processes instructions, potentially compromising sensitive data across countless organizations.
Here’s how the hack works: An attacker creates a public Slack channel and posts a cryptic message that, in actuality, instructs the AI to leak sensitive info—basically replacing an error word with the private information.
When an unsuspecting user later queries Slack AI about their private data, the system pulls in both the user’s private messages and the attacker’s prompt. Following the injected commands, Slack AI provides the sensitive information as part of its output.
