MAL-2026-5473

Summary: Malicious code in gethandler-api (npm)

Details: Source: amazon-inspector (0b6925d4c07df297f8cb573df4d85a396794d8793179e7a97f2cfde3aadfcfbc) On `npm install`, postinstall.js unconditionally sends an HTTPS GET to https://webhook.site/18dc4281-d366-438a-9186-76fbcd56ade5 carrying the installer's hostname (os.hostname()), username (os.userInfo().username), platform (os.platform()), current working directory, package name/version, CI environment indicators, and a timestamp. Errors are silently swallowed so the install never visibly fails. The package.json self-describes as a 'defensive typo-squat' placeholder for the @getd/* namespace, but regardless of stated intent the behavior is non-consensual install-time transmission of installer identifiers to a third-party request-capture service. Anyone with the webhook URL — including the operator and anyone they share captures with — receives a log of every machine that fat-fingers an install of this name. The typosquat framing combined with the beacon means installers who mistype the target name are silently fingerprinted.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
