Spotting Self-Hacking: Signs & Fixes

TL;DR

Self-hacking – where your own accounts get compromised due to weak security habits or reused passwords – is common. Look for unusual login activity, unexpected changes to settings, and strange emails. Strong passwords, two-factor authentication (2FA), and regular account reviews are key to preventing it.

How to Tell if You’ve Been Self-Hacked

  1. Unusual Login Activity: This is the biggest red flag.
    • Check Account History: Most services (Google, Facebook, banking) show recent logins – location and time. Look for anything you didn’t do.
    • Email Alerts: Enable email notifications for new logins. You’ll get a message every time someone signs in.
      (Example - Google): Settings > Security > Recent security activity
  2. Unexpected Account Changes: Things changing without your input?
    • Password Reset Emails: Receiving password reset requests you didn’t initiate is a serious warning.
    • Profile Updates: Check your profile details (name, email, phone number). Have they been altered?
    • Payment Information: Review saved payment methods and recent transactions for anything unfamiliar.
      (Example - Amazon): Your Account > Payment Options
  3. Strange Emails or Messages: Phishing attempts can lead to self-hacking.
    • Suspicious Links: Don’t click links in emails from unknown senders. Hover over them (without clicking) to see the actual destination URL.
    • Urgent Requests: Be wary of emails demanding immediate action (e.g., “Your account will be locked!”). Legitimate companies rarely use this tone.
      (Tip): Check the sender's email address carefully – is it a legitimate domain?
    • Grammar & Spelling Errors: Phishing emails often have poor grammar and spelling.
  4. Software Warnings: Your devices can alert you to problems.
    • Antivirus/Anti-malware Alerts: Pay attention to warnings about potential threats. Run a full system scan if prompted.
    • Browser Security Warnings: If your browser flags a website as unsafe, don’t proceed.

What To Do If You Suspect Self-Hacking

  1. Change Your Password Immediately: Use a strong, unique password for *every* account.
    • Password Managers: Consider using a password manager (e.g., LastPass, 1Password) to generate and store complex passwords securely.
  2. Enable Two-Factor Authentication (2FA): Adds an extra layer of security.
    • Authenticator Apps: Use apps like Google Authenticator or Authy for 2FA – more secure than SMS codes.
      (Example - Facebook): Settings > Security and Login > Two-Factor Authentication
  3. Review Connected Apps: Revoke access to any apps you don’t recognise or no longer use.
    • Google Account Access: Check which third-party apps have access to your Google account.
  4. Scan for Malware: Run a full system scan with reputable antivirus software.
  5. Contact the Service Provider: Report the incident and follow their instructions.

Preventing Future Self-Hacking

  1. Strong, Unique Passwords: Avoid reusing passwords across multiple accounts.
  2. Two-Factor Authentication (2FA): Enable it wherever possible.
  3. Regular Account Reviews: Check login activity and settings periodically.
  4. Be Careful with Phishing Emails: Don’t click suspicious links or provide personal information.
  5. Keep Software Updated: Updates often include cyber security patches.
