Slack capture+reader adapter for USRCP — vision-proof cross-channel memory via @slack/bolt + Socket Mode

AI Security Review

scanned 3h ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The package is a Slack adapter that stores user-provided config, connects to Slack, and calls Anthropic for summaries/replies during explicit setup/runtime use.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install postinstall; explicit usrcp-slack runtime or setup invocation

Impact

Install rebuilds better-sqlite3; runtime may send allowlisted Slack message content to the configured Anthropic API key as part of documented bot behavior.

Mechanism

package-aligned native rebuild plus Slack/Anthropic adapter behavior

Rationale

Static inspection found risky primitives, but they are package-aligned and user-invoked: lifecycle rebuilds a native dependency, setup validates user-supplied credentials, and runtime operates as a Slack bot using configured allowlists. No unconsented install-time agent control hijack, credential harvesting, persistence, remote payload execution, or unrelated exfiltration was found.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for block

package.json has postinstall deleting better-sqlite3 build dirs then running npm rebuild better-sqlite3
dist/index.js runtime connects Slack Socket Mode and processes allowlisted Slack messages
dist/setup.js validates user-entered Slack and Anthropic credentials over network

Evidence against

postinstall is limited to better-sqlite3 rebuild paths under node_modules; no home/project agent control-surface writes
dist/index.js child_process execSync only runs user-invoked --reset-config command: usrcp setup --adapter=slack
dist/setup.js writes package config through config.js and requires interactive TTY/masterKey
credential handling is setup/runtime aligned: Slack tokens and Anthropic key are user-entered, validated, then encrypted via usrcp-adapter-kit
no eval/vm/remote code loading, persistence, destructive broad file operations, or exfiltration endpoint outside Slack/Anthropic flow found
