From the first computer worm to modern ransomware — explore the attacks that shaped cybersecurity.
I'm self-taught in cybersecurity, learning it the way most of us actually do in 2026 — one breach write-up, one CVE, one late-night rabbit hole at a time — and I built this timeline because I wanted a single place to actually explore how these attacks unfolded instead of another wall of text. The deeper reason is simple: studying something like the Morris Worm or WannaCry teaches you the exact same patterns — phishing, unpatched software, weak MFA — that show up in attacks on regular people every day, not just banks and hospitals. So if you're new to this, welcome in; and if you already know your stuff, I hope the "why it happened" behind each entry adds something a plain summary doesn't.
Long, unique passwords for every account beat memorized ones every time. A single reused password is how most account breaches start. See recommended password managers →
MFA is the single biggest thing you can do to stop a stolen password from becoming a compromised account. App-based authenticators are safer than SMS codes. See recommended MFA apps →
Your inbox is the recovery key to almost every other account you own, so it's worth using a client that isn't mining it for ad data. See recommended email clients →
A VPN shifts trust from your network to the VPN provider — it's not automatically "more private," so the provider you pick actually matters. See recommended VPN providers →
Your browser sees everything: every site, every search, every login. The default browser on your OS is rarely built with blocking trackers or fingerprinting in mind, so it's worth switching to one that is, and pairing it with a solid ad/tracker blocker.
Most major attacks in this timeline exploited a bug that already had a patch available. Turn on automatic updates for your OS, browser, and apps.
Phishing is still behind the majority of breaches. If a message creates urgency or asks you to click something unexpected, pause before acting.
Keep an offline or cloud backup separate from your main device. It's the one thing that makes ransomware a nuisance instead of a disaster.
Avoid logging into sensitive accounts on open networks, or use a trusted VPN if you have to. Public Wi-Fi is easy to eavesdrop on.
