@or-sdk/graph@1.10.7
Malicious code in @or-sdk/graph (npm)
T1059.007 · JavaScriptT1105 · Ingress Tool TransferT1027 · Obfuscated Files or Information
Analysis
The package's preinstall hook (setup.mjs) downloads the Bun JavaScript runtime from github[.]com/oven-sh/bun and uses it to execute a 727KB obfuscated script (math_init.js) bundled in the package. The script is obfuscated with a large encoded string array and a custom decoder, and contains eval/Function-constructor and child_process invocations. The obfuscated payload is unrelated to the package's declared purpose as a graph-query SDK client; installing the package triggers this download-and-execute behaviour automatically.
