The @marketfront/footer npm package version 7.0.0 is part of a malicious campaign involving 25 packages published under the @marketfront scope. It contains a heavily obfuscated postinstall script that harvests sensitive credentials and environment data from the host system during npm install. The stolen data includes SSH keys, AWS credentials, Docker and npm configuration files, and environment variables, which are exfiltrated via DNS TXT queries and HTTPS POST requests to attacker-controlled infrastructure. The package does not provide any legitimate functionality and uses dependency confusion tactics to target specific organizations.
