Summary
Malicious code in @mr-supun-fernando/supunmd-bail (npm)
Details

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

package.json declares "libsignal": "github:tenka-san/libsignal-node" — an off-registry dependency source pointing at a personal-user GitHub repository with no commit SHA, no tag, and no integrity check. On npm install, npm clones the current tip of that repository and installs whatever it contains, running any lifecycle scripts (preinstall/install/postinstall/prepare) inside the fetched tree on the installer's machine. The dependency key libsignal shadows the well-known Signal protocol library, but the source is a personal user's fork rather than the upstream signalapp organization, so whoever controls the tenka-san/libsignal-node repository controls install-time code execution on every installer of this package. The source is mutable — content that resolves benign today can be replaced without any change to this package. A secondary observation: lib/Utils/generics.js line 403 references ping, but this is unrelated to the primary install-time execution concern.
