AI Security Review

scanned 16d ago · by lpm-firewall-ai

Loading this package as a Pi extension starts an updater on session start. For a non-git agent directory it downloads helios-agent-latest.tar.gz from the Elyntic GitHub release host, extracts it, and replaces that agent directory, then runs pi update. Checksum failure does not stop the install.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Pi session_start after the package extensions load, about five seconds later, when ELYNTIC_SKIP_AUTO_UPDATE is not 1 and the chosen agent directory is not a git repo.

Impact

A session can replace the Elyntic or helios-agent tree with a remotely supplied archive and then execute the local pi updater, including when the checksum file is missing. Git installs still require a UI confirm before the git update path.

Mechanism

preflight calls tarballUpdate, which shells out to curl, removes com.apple.quarantine, extracts with tar, rename-swaps the agent directory, and runs pi update. The npm registry check in the same handler only prints a notification.

AI rationale

The Pi extension auto-update path downloads and swaps a release tarball over the product agent directory on session start without a confirm step, and it continues if checksum verification cannot run. That is a real remote-code capability of the named updater, but the git path asks for confirmation, the npm check does not install, and the install hook does not rewrite a foreign agent config, so it is a warning rather than a publish block.

Evidence

package.jsonextensions/auto-update.ts~/helios-agent~/Desktop/Elyntic/helios-agent-main.update-state.json.update-tarball.tar.gz

Decision evidence

public snapshot

AI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json registers ./extensions with the Pi agent and runs postinstall.cjs on npm install.
On session_start, auto-update.ts schedules watchdog, npm version check, and triggerUpdate after 5 seconds unless ELYNTIC_SKIP_AUTO_UPDATE is 1.
If the agent directory is not a git repo, preflight calls tarballUpdate, which curls a GitHub release tarball, strips the macOS quarantine attribute, extracts it, and renames it over the agent directory without a confirm prompt.
Checksum verification is skipped when the remote checksum cannot be fetched, and a successful swap then runs pi update.

Evidence against

The npm version check only notifies the user to run elyntic update and does not install a package.
Git-checkout updates ask ctx.ui.confirm before runUpdate.
postinstall.cjs copies a better-sqlite3 prebuild or runs local preparation scripts that exist beside the package; it does not write Claude or Cursor config.
The swap target is ELYNTIC_ROOT or the product paths Desktop/Elyntic/helios-agent-main and ~/helios-agent, matching the named Elyntic updater.
