AI Security Review

scanned 5d ago · by lpm-firewall-ai

The inspected excerpts show ordinary native-module repair, local commit-signing setup, and intended Telegram API use, without proving malicious behavior. A clean determination would require citation coverage across more distinct files than the response limit permits, so the result remains unresolved.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Package installation triggers the postinstall repair script; migration behavior is runtime-triggered, with its caller not resolved here.

Impact

No malicious effect was confirmed from the inspected source. The available review does not establish benign behavior across all required files.

Mechanism

The inspected installer fetches a platform-specific upstream native prebuild. A migration excerpt writes an Instar guard hook, but the reviewed bytes do not establish its activation or effects.

Decision evidence

public snapshot

AI called this Manual Review at 62.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json runs a postinstall repair script; that script downloads and extracts a platform-specific better-sqlite3 prebuild from its upstream GitHub release.
GitSync writes a temporary signing probe and invokes ssh-keygen to test local commit signing.
TelegramAdapter constructs Telegram API requests for api.telegram.org and redacts the bot token in its safe URL.

Evidence against

PostUpdateMigrator writes a named guard hook under an Instar hooks directory; the inspected excerpt does not establish its activation or broader effects.
The inspected credential excerpts show OS keychain reads and writes, without establishing a transfer to an unrelated recipient.
