Security audit

Dr.Binary

Security checks across malware telemetry and agentic risk

Overview

This skill does what it claims for remote binary analysis, but users should understand that selected files are uploaded to an external sandbox.

Install only if you are comfortable using Dr. Binary/Deepbits as a remote analysis provider. Do not submit proprietary, regulated, or personal binaries unless you have permission and understand the provider’s retention and privacy terms. Use a scoped API key if available and rotate it if exposed.

MCP Least Privilege
Confidence
96% confidence
Finding
The skill reads local files, uses environment-provided credentials, invokes shell/Python, and transmits data to an external service, yet declares no permissions. That mismatch removes an important trust boundary for users and agents, making silent exfiltration of sensitive binaries or proprietary samples possible during what appears to be a local analysis workflow.

Tp4

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding
The stated purpose suggests binary analysis and reverse engineering, but the documented behavior first uploads the user's local binary to a remote external service and returns a sandbox path. In this context, that is more dangerous because malware samples, proprietary executables, credentials embedded in binaries, or regulated data may be sent off-host without the user realizing the analysis is not purely local.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
This script uploads the full contents of any local file path provided to a remote service with no interactive confirmation, allowlist, size/type restriction, or explicit warning at the point of transfer. In a security-sensitive binary-analysis workflow, that creates a real risk of accidental exfiltration of proprietary, personal, or otherwise sensitive binaries to a third party.
