A comprehensive guide to personal cybersecurity, emphasizing the evolving threat landscape from mid-2024 to mid-2025, marked by unprecedented data exposures like the 16-billion credential "GOAT" leak.

We highlight the shift in risk from corporate servers to individual user devices, largely due to infostealer malware.

The document details major data breaches across various sectors, identifying common attack vectors such as supply chain vulnerabilities, insider threats, and the sophisticated evolution of ransomware.

Crucially, we outlines a modern password and authentication strategy, advocating for long, unique passphrases, the ubiquitous adoption of multi-factor authentication (MFA)—prioritizing hardware keys and authenticator apps—and the essential role of password managers as a "digital vault" for secure credential management.

Finally, we underline the importance of proactive breach monitoring through services like "Have I Been Pwned?", cultivating phishing awareness, diligent software updates, and securing home and public Wi-Fi networks to build robust digital resilience.
