OMG! I Have Been Hacked
After my recent presentation at DevCon2024, I received an excellent question: “What should you do if you suspect you've been hacked?” This inspired me to write a practical guide on the topic, aiming to help users respond effectively and confidently if they find themselves in this situation.

For the average user, the thought of recovering from a hack can be overwhelming. No one wants to face it, but it’s a reality that everyone should be prepared for. My goal is not to create fear but to empower you with steps to take if it happens.

Stay Calm and Assess the Situation
If you suspect a security breach, the first thing to remember is to stay calm. Feeling alarmed or anxious is normal, but panicking can lead to rushed decisions. Focus on the steps ahead rather than dwelling on what happened. Accepting the situation is key to moving forward.
?
Take a moment to evaluate any unusual signs. Are there strange transactions on your accounts? Do you see unexpected login notifications? Has your device been acting differently, such as running slower, getting hotter, or draining its battery faster than usual?

Some physical symptoms of a hacked device include:
- Device running slower and fans activating more frequently without heavy usage.
- Unexpected heating of your phone or tablet without intensive app usage.
- Battery drain that’s faster than usual.
- Random restarts or shutdowns.

Key Indicators of a Potential Hack
1. Check Login History: Most platforms provide a login history feature showing device details and locations. If you see unfamiliar devices, log them out immediately. Set up login alerts for added security.
2. Password or Account Lockout Notifications: If you receive alerts about password changes you didn’t initiate or multiple failed login attempts, it could signal a hack.
3. Unusual Social Media Activity: Watch for messages, links, or posts sent from your account that you didn’t initiate. Check your activity feed and email logs.

Essential Steps to Secure Your Accounts
1. Change Passwords: Create complex passwords using a mix of uppercase, lowercase, numbers, and special characters. Avoid using easily guessed information, like birthdays or pet names.
2. Use Unique Passwords for Each Account: Using the same password across accounts is risky. A password manager can simplify managing and generating unique passwords for each account.
3. Enable Multi-Factor Authentication (MFA): MFA apps, like Google Authenticator or Microsoft Authenticator, add a valuable layer of security by requiring a code in addition to your password.
4. Log Out of All Devices: After changing your password, log out of all devices to terminate any active sessions.
5. Update Recovery Options: Set up a private recovery email, not used for social media, to enhance account recovery security.

Additional Security Practices
1. Regularly Update Your Software and Operating System: Hackers often exploit known vulnerabilities in outdated software. Regular security updates help protect your device.
2. Stay Informed on Security Threats: Keep yourself and your family updated on cybersecurity best practices to stay aware of common risks.
3. Back Up Important Data Frequently: Regularly backing up your data—whether on an external drive or cloud service—ensures you have access to critical information in case of a hack or device loss.

Being proactive and prepared makes a significant difference. Taking these steps can help you stay resilient in the face of a potential cyberattack, enabling you to manage the situation confidently.
