A new “coordinated” supply chain attack campaign has impacted eight packages on Packagist including malicious code designed to run a Linux binary retrieved from a GitHub Releases URL. “Although the affected packages were all Composer packages, the malicious code was not added to composer.json,” Socket said. “Instead, it was inserted into package.json, targeting projects that…
