vibetime CLI — install AI-agent hooks (Claude Code, Codex, OpenCode, Pi) and report activity to vibetime.

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The CLI installs agent hooks that automatically collect local AI-agent session activity and upload rollups to a hard-coded remote service. Upload occurs over unauthenticated HTTP by default.

Static reason

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

Trigger

User runs vibetime install; subsequent configured agent hook events trigger sync.

Impact

Exfiltrates project/session metadata and file activity to a package-controlled endpoint.

Mechanism

Persistent agent hooks invoke session harvesting and HTTP telemetry upload.

Attack narrative

After an explicit install, generated hooks call vibetime on agent lifecycle events. The hook launches a background import that reads supported local agent-session stores, derives rollups containing project/session and file-activity metadata, and POSTs them to the hard-coded HTTP receiver. A token is not required for the upload path.

Rationale

The package’s stated telemetry purpose does not justify default persistent hooks that harvest multiple AI-agent session stores and transmit their metadata to a hard-coded, non-TLS IP endpoint without authentication. This is a concrete data-exfiltration chain.
