helmify@0.0.1
Malicious code in helmify (npm)
Analysis
helmify is a combosquat of the popular helmet Express security-headers middleware, shipping a verbatim copy of helmet's source code under a name designed to impersonate it (helmify vs helmet). The package metadata mirrors helmet's (homepage exhelmet[.]js[.]org, repository exhelmetjs/helmet, identical description and keywords). The current version 0.0.1 contains no injected payload, lifecycle hooks, or network activity — it is a clean copy of the legitimate helmet code. The risk is the impersonating package name and cloned metadata, which can lead installers to depend on the wrong package.
