“Update required.” “Click to fix.” Stop before proceeding with the instructions. Fake alerts can trick you into compromising your devices, putting not only your information but also others at risk. Don’t click to “fix.” Verify first. #CybersecurityAwarenessMonth

Phishing doesn’t only arrive in your UN inbox. A text can look urgent, familiar or convincing and still be malicious. Before tapping a link or responding to an unexpected request, verify it through a trusted channel. Think before you tap. #CybersecurityAwarenessMonth

UN personnel connect from around the world, but cyber threats don’t take a break when we step away from our desks. Protect your mobile devices. Be cautious with unexpected texts, QR codes, links & login requests. Cybersecurity goes wherever you go. #CybersecurityAwarenessMonth

QR codes are everywhere, including in our digital workplaces. Before you scan, pause and consider where that code could take you. A malicious QR code can lead to a fraudulent website designed to steal information. #CybersecurityAwarenessMonth

At the UN, protecting our accounts helps safeguard the information and systems we rely on to carry out our work. Getting authentication prompts you didn’t initiate? Don’t approve them. Remember: Pause. Verify. Protect. #CybersecurityAwarenessMonth
