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.

The Identity Protection Maturity Myth That Leaves Enterprises Exposed
🔐 Identity Protection Maturity Is a Dangerous Illusion
⚠️ Many enterprises think they’re secure because they’ve deployed MFA, SSO, and identity tools – yet attackers still slip through.
😱 The shocking truth is that cybercriminals rarely need to hack the technology. They exploit the human layer by convincing employees to “approve” fraudulent requests or reset access controls.
📊 This maturity myth creates a false sense of safety. Dashboards look green, executives feel reassured, but real-world breaches prove otherwise.
💡 Identity protection is not about checkboxes – it’s about resilience against manipulation. The missing piece is continuous, real-world simulations that train employees to recognize and resist these tactics.
🚨 Without this, one compromised account can give attackers the keys to the kingdom.
👉 AUMINT.io’s Trident platform equips teams with tailored, evolving simulations that turn the human factor into your strongest defense.
