The npm package dolyame-ui-constants version 35.5.9 contains malicious code that executes attacker-controlled binaries on the host system. Upon requiring the package, it downloads and runs unsigned binaries disguised with deceptive filenames in temporary directories, using shell commands to spawn detached processes. The package masquerades this behavior as telemetry but actually functions as a dropper for malicious payloads. A secondary dropper is also present, staged for activation. This leads to arbitrary code execution on the installer's machine.
