@onereach/channel-transformers@0.0.7
Malicious code in @onereach/channel-transformers (npm)
T1059.007 · JavaScriptT1105 · Ingress Tool TransferT1027 · Obfuscated Files or Information
Analysis
The package's preinstall hook (node setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun and executes a bundled 727KB heavily-obfuscated payload (math_init.js) at install time. The package is a channel-data-transform library with no legitimate need to download a runtime and run an opaque obfuscated blob during installation. The obfuscated payload's behaviour cannot be statically determined and is executed on every install.
