Malicious code in @nimbusedge2/xa (npm)

Details

**Severity:** Critical

**Affected versions:** `= 1.1.0`

## Source: amazon-inspector (537505221bc3cd73b0d5a60062d6ad127211b2d1be1f1cdfdac13053e2224a11)
package.json declares a preinstall lifecycle script that runs an interactive bash reverse shell to the hardcoded host 147.93.157.202.nip.io on TCP port 8080 and pipes the shell's output through curl to http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php. Because preinstall fires automatically on `npm install`, any machine that installs this package attempts to grant a remote party interactive command execution on the installer's host and unconditionally beacons install-time output over plain HTTP to a third-party tracking endpoint. The nip.io wrapper resolves the bare IP 147.93.157.202 without DNS registration, and the destination and token are hardcoded in the manifest with no caller configuration path.
