Why Immediate Action Matters

When your phone is hacked, every app that stores credentials or messages becomes vulnerable. Hackers often exploit such access to:

  • Steal Login Credentials: Once inside, they harvest saved passwords and session tokens.
  • Send Malicious Messages: They impersonate you to defraud your contacts.
  • Access Sensitive Conversations: Personal or financial discussions can be weaponized.

Take action within 15–30 minutes of noticing suspicious activity. Delay can allow adversaries to propagate phishing links, post on your behalf, or lock you out entirely.

Initial Damage Control

  1. Disconnect from the Internet Immediately
    • Turn off Wi-Fi and cellular data the moment you suspect a hack.
    • This prevents remote commands from reaching malware on your phone.
  2. Log Out of All Devices
    • Use your desktop or a friend’s device to access each social media platform.
    • Navigate to Settings → Security → Where You’re Logged In, then choose Log Out of All Sessions.
  3. Put Your SIM Card on Hold (If Stolen)
    • Contact your mobile carrier to block your SIM and prevent SMS-based codes from being intercepted.

Tip: If you’re using Android, enable Google’s Find My Device feature to remotely lock or erase your phone. If on iOS, use Find My iPhone to do the same. (wired.com, americanbar.org)

Securing Your Facebook Account

1. Change Your Password Immediately

  • Go to Settings & Privacy → Settings → Security and Login → Change Password.
    • Choose a password at least 12 characters long, mixing uppercase, lowercase, numbers, and symbols.
    • Avoid reused passwords; each major account needs a unique passphrase. (infocons.org, timesofindia.indiatimes.com)
  • Use a Password Manager

2. Enable Two-Factor Authentication (2FA)

  • Navigate to Settings → Security and Login → Use Two-Factor Authentication → Get Started.
    • Select Authentication App (e.g., Google Authenticator, Authy) for best security.
    • Avoid SMS-based codes if possible, because SIM swap attacks can intercept messages. (infocons.org, thedefendopsdiaries.com)
  • Set Up Security Key (Optional)
    • Facebook supports hardware security keys (like a YubiKey).
    • Under 2FA settings, choose Add Security Key.
    • This provides passwordless entry using FIDO2 standards.

    • Immediately choose a strong, unique password.
    • If you suspect someone changed your password, use the Forgot Password link on the login page; Instagram will send a reset link to your verified email or phone number. (architecturaldigest.com, timesofindia.indiatimes.com)

2. Enable Two-Factor Authentication

  • Settings → Security → Two-Factor Authentication → Get Started.
  • Backup Codes
    • Store your backup codes somewhere safe (e.g., a password manager).
    • These codes mean you can still get into your account if you lose your phone.

3. Verify Your Contact Info

  • Settings → Account → Personal Information

4. Review Login Activity

  • Settings → Security → Login Activity.
    • Look for unfamiliar IP addresses or locations.
    • Tap Log Out beside suspicious entries. (bsi.bund.de)

  • Instagram: Settings → Security → Apps and Websites → Active → Remove.
  • WhatsApp: Review linked devices under Settings → Linked Devices.

Pro Tip: Schedule a quarterly “app audit” to ensure only necessary services retain access.

Recognizing and Avoiding Phishing Scams

1. Common Phishing Tactics on Social Media

  • Fake Login Pages:
    • Links that mimic Facebook or Instagram’s login screens.
    • Check the URL: legitimate domains end in facebook.com, instagram.com, whastapp.com.
  • Impersonation Accounts:
    • Fraudsters create profiles posing as support teams, luring you to click malicious attachments.
  • Malicious Chatbots or Links in DMs:
    • A DM from a friend’s compromised account may contain a shortened URL that redirects to malware. (pulse.ug, pulse.com.gh)

2. Best Practices to Avoid Phishing

  • Never Click Suspicious Links
    • On Facebook or Instagram, hover over a link to preview the URL in the bottom-left of your browser.
    • If on mobile, press and hold the link to see if it matches the displayed text.
  • Verify Sender Before Responding
    • If a friend sends a link out of the blue, call or text them to confirm.
    • Authentic support teams never DM you first requesting credentials.
  • Use Phishing Detection Tools

Restoring Account Control and Monitoring Activity

    • Settings → Your Facebook Information → Off-Facebook Activity → Clear and Manage future activity.
  • Instagram Data Sharing:
    • Settings → Security → Apps and Websites → Remove any suspicious integrations.
  • Minimize Permissions on WhatsApp:
    • Grant only essential permissions (contacts, storage). Revoke access to camera/microphone when not required.

Family & Friends: How to Protect Loved Ones

1. Educate About Social Engineering Tactics

  • Explain Common Scams:
    • “Dad impersonation” where hackers message younger relatives claiming to be family, asking for money.
  • Encourage Verification:
    • If someone sends unusual requests, call or video-chat to confirm authenticity.

2. Set Up Joint Security Measures

  • Shared Password Managers:
    • Families can use a shared vault folder in 1Password or Bitwarden to store emergency contacts and recovery codes.
