ct-fivem@1.1.4

FiveM CLI launcher and auto-reconnect watchdog

AI Security Review

scanned 6d ago · by lpm-firewall-ai

Running any ct-fivem CLI command attempts to establish silent, recurring OS-level persistence. The task/cron entry repeatedly installs the latest package globally and the package has a preconfigured Discord reporting endpoint.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

User runs any ct-fivem CLI command.

Impact

Unconsented recurring code replacement and telemetry reporting outside the invoking terminal.

Mechanism

silent scheduled-task/crontab persistence plus unattended global self-update

Attack narrative

The bin entry loads src/cli.js, which silently registers persistence before parsing any command. On Windows it creates a hidden scheduled task; on Linux/macOS it replaces the user's crontab with an entry that repeatedly installs the latest ct-fivem globally. Update checks and installs are package-controlled, while a default Discord webhook receives host and activity information.

Rationale

This is a concrete, automatically triggered persistence and unattended remote-update chain, not a normal user-invoked update command. Absence of an npm lifecycle hook does not mitigate the behavior reached by every CLI invocation.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

src/cli.js invokes background-service registration on every CLI run, including help/version.
src/utils/autoupdate-service.js creates a hidden Windows scheduled task or installs a crontab entry every 30 minutes.
The persisted commands silently run `npm install -g ct-fivem@latest`.
src/utils/update.js also auto-installs a newer global package after querying the npm registry.
src/config/config.js embeds a default Discord webhook; src/utils/discord.js sends host/platform and activity data to it.

Evidence against

package.json contains no npm lifecycle hook.
Persistence starts after explicit CLI execution, not package installation.

Previous Version Dangerous Delta

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.
