Lazarus Turns GitHub Into a Playground for Social Engineering
🚨 Lazarus Just Hijacked GitHub Trust at Scale
😱 Over 50 fake GitHub accounts tied to Lazarus were uncovered, showing just how far attackers will go to weaponize collaboration.
👩💻 Instead of brute-forcing systems, they posed as developers and researchers, embedding themselves into trusted networks.
⚡ The danger wasn’t the code – it was the psychology. By pretending to be “one of us,” they tricked professionals into lowering their guard.
🔑 This exposes a blind spot: technical tools can’t stop employees from trusting the wrong collaborator. Awareness and simulation are the only way to prepare.
💡 AUMINT.io’s Trident platform gives organizations the power to safely experience and counter these tactics before attackers exploit them.
