Summary
Malicious code in @airbnb-extended/typescript-config (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (8424e4bf8731b950511535a2cb9b41b0bedba02092a73ea304b6730f04aa95fe)

package.json for @airbnb-extended/typescript-config@99.9.1 declares a dependency ltidisafe sourced from a bare HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.8.tgz) instead of a registry version range. On npm install, npm fetches and installs whatever bytes that URL returns, executing any lifecycle scripts inside the fetched tarball. The source is unpinned by integrity hash, is not the npm registry, and is unrelated to any Airbnb-published infrastructure. The scope/name also mimics the well-known @airbnb/typescript-config package, and the version 99.9.1 is implausibly high — a dependency-confusion / lure shape designed to win resolution against a legitimate internal or public package. The tarball URL is mutable by whoever controls the storage bucket, so the delivered payload can change at any time.
