Official description
package.json declares
"loadash": "^1.0.0" as a runtime dependency. loadash is a well-known typosquat of lodash and is never required or imported anywhere in this package's source — the dependency is unused by the scanner itself. Every installer of this package pulls loadash@^1.0.0 into their node_modules transitively, executing whatever code that namesquat ships. The remaining static signals on this package (curl/ping/POST/child_process/https patterns across src/scanner/, src/ioc/, src/rules/, src/ml/, src/sandbox/) are consistent with the package's stated purpose (a supply-chain security scanner that inspects other packages' lifecycle scripts, fetches package metadata from registry.npmjs.org, and analyzes IOC patterns like curl http://evil.com as data); literal strings like curl http://evil.com and $(whoami) appear as detection rule examples, not as executed commands. The block is on the namespace-abuse vector — a security tool has no legitimate reason to ship an unused typosquat dependency, and installers should not silently acquire it.What should I do about MAL-2026-4616?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
