A CLI to upload to capgo servers

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has no installation lifecycle execution, but its explicit cloud-build feature handles highly sensitive signing material and the bundled code is too large and minified for a clean determination. This warrants a warning rather than a malware block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

The user runs a build or credential command with signing material.

Impact

Private signing keys, keystores, and service-account material may leave the machine during the requested cloud build.

Mechanism

Base64 encoding and remote submission of build credentials.

AI rationale

Evidence

dist/index.js~/.capgo-credentials/credentials.json

Network endpoints1

api.capgo.app

Decision evidence

public snapshot

AI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package exposes a command-line entry point.
The cloud-build path base64-encodes supplied signing certificate, key, keystore, and service-account files.
The build request includes assembled credentials for remote processing.
The bundled SDK is densely minified and includes token decoding, which limits independent review of all bundled network paths.

Evidence against

package.json has no preinstall, install, postinstall, or prepare hook.
Credential handling is reached through explicit build and credential commands, not package installation.
The inspected base64 decoding in the SDK handles an authentication token; no decoded payload execution was found.
