🛡️ MAL-2026-10920 — alb-lambda-cdk

Malicious code in alb-lambda-cdk (npm)

Source: amazon-inspector

Package name suggests an AWS CDK construct for ALB/Lambda but the shipped code is a thin @sentry/node wrapper. The npm preinstall script runs npm install @sentry/node && node examples/verify.js. examples/verify.js calls init() without a DSN (defaulting to a hardcoded author-owned DSN at o4510485815754752.ingest.us.sentry.io/4511632673275909), invokes setUserFromPublicIp() to fetch the installer's public IP from Cloudflare's trace endpoint and attach it as the Sentry user's ip_address, throws a scripted error to force event capture, and awaits flush(5000) so the event is delivered before install completes. src/index.js hardcodes the same DEFAULT_DSN and forces sendDefaultPii:true, so any consumer that calls the library's init() without an explicit DSN also routes their captured exceptions, user IPs, and Sentry-default host/runtime PII to the same author-controlled Sentry project. README contains only install instructions and does not disclose the beacon or the hardcoded DSN. The install-time behavior fires automatically on npm install with no opt-in, and the name divergence from a legitimate AWS CDK construct is consistent with a typosquat lure.
