The Five Eyes intelligence alliance has issued a warning about China’s ongoing campaign to recruit Western government employees and contractors via LinkedIn, offering cash in exchange for state secrets. The tradecraft involves seemingly innocuous connection requests that escalate into paid intelligence relationships. This is a long-running threat that intelligence officials say continues to grow in scale and sophistication.

Architect’s Take: Cloud security architects with clearances or access to sensitive government cloud environments should review their organisation’s social media policies and ensure staff handling sensitive infrastructure are briefed on LinkedIn-based social engineering. Consider implementing insider threat monitoring and reinforcing acceptable use policies around unsolicited professional contact from unknown foreign nationals.
