Account Takeovers: What They Are and How to Protect Yourself
As cybercrime continues to evolve, one of the fastest-growing threats to individuals and businesses is the account takeover, when a bad actor gains unauthorized access to an online account and uses it for malicious purposes.
From email and social media to banking and investment platforms, no account is off-limits. But the good news is with the right security practices and awareness, you can dramatically reduce your risk.
What Is an Account Takeover?
An account takeover (ATO) occurs when a cybercriminal gains access to someone’s online account and assumes control. Once inside, they can:
- Steal personal or financial data
- Access payment information
- Impersonate you or your business
- Launch further attacks or scams
The damage depends on the type of account compromised, how long they maintain access, and how quickly the issue is detected.
How Do Account Takeovers Happen?
Cybercriminals use a variety of tactics to compromise accounts. Here are the most common methods:
- Credential Stuffing: Hackers use previously stolen usernames and passwords,often found on the dark web, and try them across multiple platforms, taking advantage of reused credentials.
- Tip: Always use unique passwords for each account.
- Phishing: Fraudulent emails or messages trick users into clicking malicious links or giving away sensitive information. These attacks have become increasingly sophisticated, and often appear to come from trusted sources.
- Tip: Never click unknown links or download unexpected attachments.
- Malvertising: Malicious ads can infect your device with malware that steals session cookies, allowing attackers to “hijack” your login session without needing your password.
- Tip: Keep your browser updated and avoid clicking suspicious ads.
- Man-in-the-Middle (MITM) Attacks: On unsecured public Wi-Fi networks, attackers can intercept unencrypted traffic and hijack your session, all without your knowledge.
- Tip: Avoid public Wi-Fi or use a VPN to encrypt your connection.
How to Defend Against Account Takeovers
Preventing account takeovers comes down to layered security and digital awareness. Here are essential steps you can take today:
- Use strong, unique passwords for every account
- Enable multi-factor authentication (MFA) whenever possible
- Use a reputable password manager to store and encrypt your credentials
- Watch for phishing red flags like typos, urgent language, and unfamiliar email addresses
What to Do If You’re a Victim
Even with the best defenses, no one is 100% immune. If you believe an account has been compromised:
- Disconnect your device from the internet to stop further access.
- Run antivirus and malware scans immediately.
- Change all passwords, especially for key accounts like email, banking, and password managers.
- Freeze your credit and notify your bank to prevent fraud.
- Work with a cybersecurity or IT professional to ensure your device and accounts are secure.
