State-sponsored threat actors (such as Lazarus Group) create thousands of fake LinkedIn recruiter profiles with AI-generated headshots. They reach out to software developers, defense contractors, and Web3 engineers with lucrative job offers, asking them to clone a GitHub repo or execute a coding challenge that installs remote access trojans (RATs).

Signs to look for

1AI headshot with perfectly centered eyes

Headshot aligns with the StyleGAN/Midjourney eye-centering rule: pupils sit at the exact horizontal midpoint of the image canvas.

2Urgent request to run a coding challenge on your local machine

They send a zip file or GitHub link containing obfuscated npm/pip dependencies with post-install malware scripts.

How to protect yourself and take action

1

Run recruiter headshot through Sealed Rose

Check for GAN/Diffusion face synthesis markers.

2

Never run unvetted candidate code on your bare metal

Always sandbox coding challenges in ephemeral cloud VMs or isolated containers.

The "contagious interview" malware attack

  • Malicious dependency poisoning: The coding test includes a `package.json` with a malicious `preinstall` hook that exfiltrates browser cookies and SSH keys.

Frequently asked questions

Why are fake recruiters sending coding tests?

They use coding tests as a trojan horse to deliver malware directly onto developer laptops, stealing API keys, crypto wallets, and proprietary source code.
