@or-sdk/payments@3.2.7
Malicious code in @or-sdk/payments (npm)
T1059.007 · JavaScriptT1105 · Ingress Tool TransferT1027 · Obfuscated Files or Information
Analysis
The package's preinstall hook (node setup.mjs) downloads the Bun runtime from the official oven-sh/bun GitHub releases and uses it to execute a bundled 727KB script (math_init.js) at install time. The script is heavily obfuscated with a custom encoded string-array decoder, concealing its behavior; no readable logic or network destination is recoverable from the source. The payload executes on every install of the package.
