Cybersecurity Basics: Protecting Yourself Online in 2026

Why You're a Target (Yes, You)

The misconception:

"I'm not important enough to hack"

Wrong. You're valuable because:

1. Your data sells:

• Stolen credit card info: $1-50 on dark web
• Full identity (SSN, DOB, address): $50-200
• Email account access: $1-20
• Social media account: $5-50
• Medical records: $50-250 (most valuable—used for insurance fraud)

Hackers target thousands at once—you're one of many

2. You're a stepping stone:

• Hack your email → reset passwords for banking, shopping, social media
• Hack your Facebook → scam your friends and family
• Hack your work email → access company systems (ransomware attacks)

One compromised account = dominoes fall

3. Automated attacks don't discriminate:

• Bots try millions of common passwords on millions of accounts
• If your password is "Password123" or "Summer2023", you're getting hacked
• Takes zero human effort—pure volume

You're not individually targeted, but you're definitely targeted

The Password Problem (And Solution)

Biggest security vulnerability:

Why most passwords fail:

Common mistakes: ❌ Using same password everywhere ("Password123" for Netflix, bank, email) ❌ Weak passwords ("fluffy123", "iloveyou", "qwerty") ❌ Predictable patterns (name + birth year: "Sarah1995") ❌ Writing passwords on sticky notes ❌ Sharing passwords with friends/family

If ONE site gets hacked (happens constantly), hackers try that username/password combo EVERYWHERE

The solution: Password manager

What it is: Software that generates and stores unique, complex passwords for every account

How it works:

1. Create ONE master password (only one you remember)
2. Password manager generates random passwords for each site (example: "X7$mK9!pL2@vN4")
3. Auto-fills when you log in
4. Encrypted, so even password company can't see your passwords

Best password managers:

1Password: $2.99/month ⭐⭐⭐⭐⭐

• Most user-friendly
• Works on all devices
• Family plan $4.99/month (5 people)

Bitwarden: Free or $10/year ⭐⭐⭐⭐⭐

• Open-source (security experts can audit code)
• Free version excellent
• Best value

Dashlane: $4.99/month ⭐⭐⭐⭐

• Dark web monitoring
• VPN included
• More expensive

LastPass: $3/month ⭐⭐⭐

• Was great, had security breach (2022)
• Still okay but trust damaged

Setting up password manager (30 minutes):

Step 1: Choose one (start with Bitwarden free) Step 2: Create strong master password

• 4-5 random words: "correct-horse-battery-staple"
• 16+ characters
• Memorize it (write it down temporarily, destroy after memorized) Step 3: Install browser extension + phone app Step 4: As you log into sites, save passwords in manager Step 5: Go to important accounts (email, bank), change passwords to randomly generated ones

After setup: You'll only remember ONE password (master), manager handles rest

Two-Factor Authentication (2FA): Your Second Line of Defense

What it is:

2FA = something you know (password) + something you have (phone)

How it works:

1. You enter password
2. Site sends code to your phone (via text or app)
3. You enter code
4. You're logged in

Why it matters: Hacker steals your password, but they don't have your phone—can't get in

Statistics: 2FA blocks 99.9% of automated attacks (Microsoft study)

Types of 2FA (from worst to best):

SMS/Text codes (okay, but not best):

• ✅ Better than nothing
• ❌ Vulnerable to SIM swapping (hacker transfers your number to their SIM)
• ❌ Requires cell signal

Authenticator apps (better): ⭐⭐⭐⭐⭐

• Google Authenticator, Microsoft Authenticator, Authy (best—cloud backup)
• Generates 6-digit codes that change every 30 seconds
• Works offline
• Free

Hardware keys (best, but overkill for most): ⭐⭐⭐⭐⭐

• Physical USB device (YubiKey: $25-45)
• Must physically insert to log in
• Unhackable remotely
• For high-security needs (journalists, activists, executives)

Which accounts MUST have 2FA:

Priority 1 (enable immediately): ✅ Email (Gmail, Outlook, etc.)—controls password resets for everything ✅ Banking/financial accounts ✅ Password manager ✅ Cloud storage (Google Drive, Dropbox, iCloud)

Priority 2 (enable this week): ✅ Social media (Facebook, Instagram, Twitter) ✅ Amazon/shopping accounts (saved payment methods) ✅ PayPal/Venmo/Zelle ✅ Work email

How to enable:

• Go to account security settings
• Look for "Two-factor authentication" or "Two-step verification"
• Follow setup (usually scan QR code with authenticator app)
• Save backup codes somewhere safe (if you lose phone)

Phishing: The #1 Way People Get Hacked

What it is:

Phishing = fake emails/texts/websites tricking you into giving up info

Common phishing tactics:

1. Fake company emails:

• "Your Amazon order for $800 TV is processing. Didn't order this? Click here to cancel."
• Link goes to fake Amazon site (amazon-verify-account.com instead of amazon.com)
• You enter password → hacked

2. Urgent warnings:

• "Your Netflix account has been suspended. Update payment now."
• "Your bank account has suspicious activity. Log in immediately."
• Creates panic → bypasses critical thinking

3. Package delivery scams:

• "Your package couldn't be delivered. Click to reschedule."
• Fake UPS/FedEx/USPS sites

4. IRS/Government impersonation:

• "You owe back taxes. Arrest warrant issued unless you pay."
• Real IRS never contacts via email/text

5. Romance/Social engineering:

• Match on dating app, quickly moves to text/WhatsApp
• Builds relationship, eventually asks for money or gift cards
• Preys on loneliness

How to spot phishing:

Red flags:

🚩 Urgency/Threats: "Act now or account will be closed!" 🚩 Generic greetings: "Dear customer" (real companies use your name) 🚩 Misspellings/Grammar: Professional companies proofread 🚩 Suspicious sender: hover over email address—is it really from amazon.com or amazon-support-center.com? 🚩 Unexpected attachments: Don't open unless you were expecting it 🚩 Too good to be true: "You've won $1,000,000!" 🚩 Shortened URLs: bit.ly links hide true destination

What to do instead:

✅ Don't click links in emails

• Instead, manually type website (amazon.com) in browser
• Or use bookmarked link
• Or use company's official app

✅ Verify sender:

• Call company using number from official website (not number in email)
• "Did you send me an email about suspended account?"

✅ Check URL carefully:

• Real: https://www.amazon.com
• Fake: https://www.amazon-account-verify.com
• Fake: https://www.arnazon.com (looks similar, but wrong)

✅ When in doubt, delete

• Legitimate companies don't threaten via email
• If it's real, they'll contact you another way

Public WiFi: Danger Zone

Why it's risky:

Public WiFi = broadcasting your data

What hackers can see on unsecured public WiFi:

• Websites you visit
• Passwords (if site not using HTTPS)
• Credit card numbers
• Messages

Attacks:

• Evil twin: Fake WiFi hotspot named "Starbucks WiFi"—you connect, hacker sees everything
• Man-in-the-middle: Hacker intercepts traffic between you and website

How to stay safe on public WiFi:

Option 1: Use VPN (Virtual Private Network) ⭐⭐⭐⭐⭐

What VPN does:

• Encrypts all your internet traffic
• Even on public WiFi, hacker sees gibberish

Best VPNs:

• NordVPN: $3.99/month (2-year plan) ⭐⭐⭐⭐⭐
• Surfshark: $2.49/month ⭐⭐⭐⭐⭐
• Mullvad: $5.50/month (privacy-focused) ⭐⭐⭐⭐⭐

Free VPNs: Avoid (they sell your data—defeats purpose)

Option 2: Use phone hotspot instead of public WiFi

• Your cellular data is encrypted
• Safer than coffee shop WiFi
• Check data plan limits

Option 3: Only visit HTTPS sites

• Check for padlock icon in browser
• HTTPS = encrypted (safer)
• HTTP = unencrypted (avoid on public WiFi)

Option 4: Don't do sensitive tasks on public WiFi

• Banking, shopping, entering passwords = wait until home

Software Updates: Boring But Critical

Why updates matter:

Updates patch security holes hackers exploit

Famous example:

• WannaCry ransomware (2017) exploited Windows vulnerability
• Microsoft released patch months earlier
• People who didn't update = infected, files encrypted, ransom demanded
• People who updated = safe

Enable automatic updates: ✅ Operating system (Windows, macOS, iOS, Android) ✅ Web browsers (Chrome, Firefox, Safari) ✅ Apps (especially banking, shopping, social media)

"Remind me later" = eventually getting hacked

Social Media Privacy

Oversharing = identity theft goldmine:

Information hackers piece together:

Public info:

• Full name + birthday (security question answers)
• Hometown (security question)
• Mother's maiden name (in tagged photos/posts)
• Pet's name (security question)
• High school (security question)
• Where you are right now (burglars know you're not home)

Privacy settings (do now):

Facebook:

• Settings → Privacy → Who can see your posts? → Friends (not Public)
• Settings → Timeline and Tagging → Review posts you're tagged in
• Hide birth year (month/day okay, year = identity theft)

Instagram:

• Settings → Privacy → Private Account (approve followers)
• Don't share live location
• Disable location on old posts (Settings → Privacy → Location Services)

LinkedIn:

• Settings → Visibility → Edit public profile → Limit visible info

General rule: If you wouldn't shout it in a crowded mall, don't post it publicly

Email Security

Your email = keys to your digital kingdom:

Email security checklist:

✅ Unique password (via password manager) ✅ 2FA enabled (authenticator app) ✅ Recovery email/phone updated (for account recovery) ✅ Check "Devices & activity" (Google/Outlook)—see if someone logged in from unknown location ✅ Review "Connected apps" (revoke access for apps you don't use)

If email gets hacked:

1. Change password immediately (from secure device)
2. Check recovery email/phone (hacker may have changed it)
3. Scan all devices for malware
4. Change passwords on linked accounts (banking, social, shopping)
5. Enable 2FA
6. Notify contacts (hacker may have sent scam emails)

Device Security

Physical and digital:

Computer/Phone basics:

✅ Screen lock (PIN/password/fingerprint)

• Auto-lock after 1-2 minutes ✅ Encryption (enabled by default on iPhone/modern Android, check Windows/Mac settings) ✅ Antivirus (Windows: built-in Windows Defender sufficient, Mac: less critical but consider Malwarebytes) ✅ Firewall enabled (usually default on) ✅ Find My Device enabled (iPhone: Find My, Android: Find My Device)—remotely wipe if stolen

Backup data:

• Cloud (iCloud, Google Drive) + external hard drive
• If device hacked/ransomed, you don't lose everything

What to Do If You Get Hacked

Damage control:

Immediate steps:

1. Change passwords (from secure device):

• Start with email (most important)
• Then banking, social media, shopping
• Use password manager to generate new strong passwords

2. Enable 2FA (if not already)

3. Check financial accounts:

• Unauthorized charges?
• Report to bank immediately
• Fraud protection usually covers you

4. Scan for malware:

• Malwarebytes (free scan)
• Delete suspicious programs

5. Alert contacts:

• "My account was hacked, ignore any weird messages"

6. Freeze credit (if identity stolen):

• Equifax, Experian, TransUnion (free)
• Prevents hackers opening accounts in your name

7. File identity theft report:

• IdentityTheft.gov (FTC)
• Creates recovery plan
