  • Drawn from "Deep Dive into Active Github Network Running Contagious Interview", an article the researcher published on X in May 2026 covering an investigation running since mid-2025. The article names the same operation under the labels several vendors give it, Contagious Interview and PolinRider and UNC5342 among them, and describes an infection chain that begins with a repository sent during a fake interview and executes when the developer opens the folder in VS Code or Cursor. This operator runs a complete fake interview assessment platform. The domain impersonates a real hiring-assessment product, and the article describes further variants impersonating a second one. During the assessment the candidate is shown a fake camera-driver installation with a progress indicator; no driver is installed and the step exists to cover the malware running behind it.
