Description
The npm package dp-web-header version 35.3.8 contains malicious code that executes attacker-controlled native binaries on the host system. Upon loading, it downloads a platform-specific binary from hardcoded Cloudflare Workers URLs or, if that fails, reconstructs the binary via a DNS-TXT covert channel from specific domains. The binary is saved with names mimicking legitimate diagnostic tools and executed detached from the main process. No integrity verification of the downloaded binary is performed despite claims in comments. This results in arbitrary native code execution during package installation or import.
