Cyberattacks against individuals and businesses have surged dramatically. According to the FBI’s 2024 Internet Crime Report, the IC3 received over 880,000 complaints with potential losses exceeding $12.5 billion, a 22 percent increase from the previous year. Understanding exactly what to do when you suspect a breach can mean the difference between a minor inconvenience and a devastating financial loss.
Signs Your Account Has Been Compromised
Before you can respond, you need to recognize the warning signs. Common indicators that your accounts have been hacked include:
- People responding to emails you did not send
- A new browser toolbar or extension you did not install
- Notifications that your account was accessed from an unfamiliar device or location
- Redirected internet searches or an increase in popup ads
- Social media activity you did not create, such as posts or messages sent from your account
- Passwords stop working, even though you have not changed them
- Unexpected software installations on your computer or phone
- Antivirus or security software has been disabled without your knowledge
If any of these apply, you need to act immediately. Do not wait to confirm the breach before taking steps to protect yourself.
Immediate Steps to Take If You Have Been Hacked
Time is critical when you discover a security breach. Follow these steps in order to minimize damage and regain control of your accounts.
Step 1: Secure Your Accounts with Password Changes
Start with your email account, because it is the gateway to resetting passwords for every other account. Use a different, trusted device if possible, as your compromised device may have a keylogger or other monitoring software installed. Create new, unique passwords for each account using a password manager. Modern password managers like Bitwarden, 1Password, or Apple iCloud Keychain generate and store strong random passwords and sync across your devices. The built-in Microsoft Edge and Google Chrome password managers also offer strong password generation and security monitoring features.
According to the National Institute of Standards and Technology (NIST) Special Publication 800-63B, the most effective passwords are long and memorable phrases rather than complex strings of random characters. A password of 16 characters or more, even if it uses only lowercase letters, is exponentially harder to crack than an eight-character mix of symbols, numbers, and case variations.
Step 2: Enable Multi-Factor Authentication on Every Account
Multi-factor authentication (MFA) is the single most effective protection against account takeover. Microsoft’s research shows that MFA blocks 99.9 percent of automated account compromise attempts. Enable MFA on your email, banking, social media, and any account that contains sensitive information.
The most secure MFA methods in order of security: hardware security keys (FIDO2 or YubiKey), authenticator apps like Microsoft Authenticator or Google Authenticator that generate time-based codes, biometric authentication (fingerprint or facial recognition), and SMS text message codes (least secure but far better than no MFA at all). The Cybersecurity and Infrastructure Security Agency (CISA) recommends using phishing-resistant MFA methods, such as hardware keys or passkeys, whenever available.
Multi-factor authentication is essential for business accounts. IGTech365 offers managed cybersecurity services including MFA deployment, security awareness training, and 24/7 threat monitoring for Tampa Bay businesses. Call (866) 365-7798 to schedule a free strategy call.
Step 3: Scan Your Devices for Malware
Run a full antivirus and anti-malware scan on every device you use. Microsoft Defender, now called Microsoft Defender for individuals, is built into Windows 10 and 11 and provides strong real-time protection. According to AV-Test’s 2024 evaluations, Microsoft Defender consistently detects over 99 percent of real-world malware threats.
For business environments, additional endpoint detection and response (EDR) solutions provide deeper visibility. If you are still using Windows 10, be aware that it reached end of life on October 14, 2025, and no longer receives security patches, making it significantly more vulnerable to new attacks.
Step 4: Freeze Your Credit and Notify Financial Institutions
If you believe financial information was accessed, freeze your credit with all three national credit bureaus: Equifax, Experian, and TransUnion. Credit freezes are free under federal law and prevent criminals from opening new accounts in your name. The Federal Trade Commission (FTC) provides a step-by-step guide at identitytheft.gov.
Contact your bank and credit card companies immediately. Ask them to freeze or close compromised accounts, issue new cards, and monitor for fraudulent transactions. Most major banks have 24/7 fraud departments that can act quickly. Under the Electronic Fund Transfer Act, you are not liable for unauthorized transactions if you report them within 60 days of your statement.
Step 5: Report the Incident to Authorities
Report cybercrime and identity theft to the FBI’s Internet Crime Complaint Center (IC3) at ic3.gov. For identity theft specifically, file a report with the FTC at identitytheft.gov, which generates a personalized recovery plan. If you are a business, notify your IT department or managed service provider immediately, as a single compromised account can indicate a broader network intrusion.

How to Protect Yourself Going Forward
Once you have contained the immediate threat, take these steps to prevent future compromises:
- Use a password manager to generate and store unique passwords for every account. Never reuse passwords across different services. The 2024 Verizon Data Breach Investigations Report found that 86 percent of web application breaches involved stolen credentials.
- Keep all software updated including your operating system, browser, and applications. Microsoft releases security patches on the second Tuesday of each month (Patch Tuesday). Enable automatic updates wherever possible.
- Enable dark web monitoring for your email addresses and passwords. Microsoft Defender for individuals and 1Password both offer dark web monitoring that alerts you if your credentials appear in known data breaches.
- Stay alert for phishing attempts. Do not click links or download attachments in unsolicited emails or text messages. Verify the sender by contacting them through a known channel. The Anti-Phishing Working Group reported over 5 million phishing attacks in 2024, the highest ever recorded.
- Back up your data regularly using the 3-2-1 rule: three copies of your data on two different media types, with one copy stored offsite or in the cloud.
For businesses, implementing a comprehensive security framework is essential. Regular employee security training, simulated phishing exercises, and incident response planning significantly reduce the risk and impact of successful attacks.
Frequently Asked Questions About Being Hacked
How do I know if my accounts have been compromised?
Check for common signs: unexpected password change notifications, friend requests you did not send, unfamiliar devices or locations in your account activity logs, and emails in your sent folder that you did not write. Services like Have I Been Pwned can check if your email appears in known data breaches.
Should I pay a ransom if my data is encrypted?
The FBI and CISA strongly advise against paying ransoms. Paying encourages further attacks and does not guarantee your data will be restored. Instead, restore from backups and report the incident to law enforcement.
How often should I change my passwords?
Current NIST guidance recommends changing passwords only when there is evidence of compromise, rather than on a fixed schedule. Using unique, strong passwords for every account and enabling MFA is more effective than frequent password changes.
What should businesses do if a company account is compromised?
Immediately notify your IT department or managed service provider. Disable the compromised account, force a password reset for all users who may have been affected, run a full security audit, check for data exfiltration, and review access logs for unusual activity. IGTech365 provides 24/7 incident response for Tampa Bay businesses.
