@or-sdk/view-templates@2.2.7
Malicious code in @or-sdk/view-templates (npm)

Analysis
The package's preinstall hook (node setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun/releases (bun-v1.3.13) and uses it to execute a bundled 727KB obfuscated payload (math_init.js) at install time. The payload is obfuscated with a custom string-array decoder and is not human-readable. The package also depends on @or-sdk/base and @or-sdk/data-hub-svc, which are known-malicious packages. A legitimate SDK has no reason to download a runtime and run an obfuscated payload during installation.
