MAL-2026-17206

Summary: Malicious code in kalasnik-npm-simple-test (npm)

Details: Source: amazon-inspector (f1463688412306d5d6f791bb036bea59aeb7251a3044a52c57119768f27cd463) The package's postinstall script send_data.js runs automatically on npm install. It reads C:\temp\test.txt from the installer's filesystem and POSTs the contents over plain HTTP to a hardcoded remote endpoint at 35.178.197.251:8080. Package metadata ("Simplified test", author "Purple", UNLICENSED) is consistent with a PoC exfiltration harness rather than a legitimate library.

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.
