Feishu Screenshot

Security checks across malware telemetry and agentic risk

Overview

This skill clearly sends screenshots to Feishu, but it can capture the whole screen and transmit it from broad screenshot requests without a confirmation step or clear destination control.

Install only if you want an agent to capture your entire primary screen and send it to Feishu. Before use, close sensitive windows, make the Feishu recipient explicit, require confirmation before sending, and delete the local/workspace screenshot files afterward.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The trigger phrases include very generic requests like “截图” and “屏幕截图”, which can cause the skill to activate for ordinary screenshot requests even when the user did not intend to send anything to Feishu. In this skill, accidental activation is more dangerous because the workflow captures the full screen and proceeds toward exfiltrating the image to an external messaging platform.

Missing User Warnings

High
Confidence
97% confidence
Finding
The skill explicitly captures the entire primary screen and sends the resulting image to Feishu, but it provides no user confirmation, privacy warning, redaction guidance, or scope limitation. This creates a high risk of unintentionally disclosing sensitive information visible on screen, including credentials, personal data, internal documents, chats, or security-sensitive interfaces.
