Overview

node-ipc is a malicious package. This package contains malicious code, that targets users with IP located in Russia or Belarus, and overwrites their files with a heart emoji.

Note: from versions 11.0.0 onwards, instead of having malicious code directly in the source of this package, node-ipc imports the peacenotwar package that includes potentially undesired behavior.

Malicious Code:

Note: Don't run it!
