AI Phishing Attacks: How to Secure Your Accounts

AI-powered phishing can make fake emails, texts, calls, and login pages unusually convincing. These steps help protect your accounts by reducing the chance that a stolen password or one mistaken click gives someone access. Start with access to your important accounts and a few minutes to review their security settings.

What You’ll Need

• A trusted device and internet connection, updated with current security and browser updates.
• Access to the email account and phone number used for account recovery.
• A password manager, if available, and an authenticator app or security key for multifactor authentication.
• A few minutes to review your most important accounts, starting with email, financial services, cloud storage, and social media.

Step-by-Step

1. Secure your primary email account first. Email is often the reset route for other accounts. Open the service by typing its known address or using its official app, not a link in a message. Review the account’s security page, recovery email and phone number, signed-in devices, and recent activity. Remove anything you do not recognize, and change the password if there is suspicious activity.
2. Use a unique, long password for every account. A password manager can generate and store different passwords, so one breach does not expose several services. Change reused or exposed passwords, prioritizing email and accounts that can reset other passwords. Never share a password or one-time verification code with someone who contacts you.
3. Turn on multifactor authentication (MFA). Find it in the account’s security or sign-in settings. Use a passkey or hardware security key where supported; these are designed to resist fake-site credential theft. Otherwise, an authenticator app is generally preferable to text messages, which can be vulnerable to phone-number takeover. Any MFA is usually better than none. Save recovery codes somewhere private and offline, not in the same account they protect.
4. Protect account recovery. Check that recovery addresses and phone numbers belong to you and are current. Add a separate recovery method if the service supports it, and secure that method with a unique password and MFA too. Do not approve an unexpected sign-in prompt or recovery request. Attackers may repeatedly prompt you, hoping you will accept one by mistake.
5. Make sign-in links a deliberate choice. A convincing message can use your name, familiar logos, fluent writing, or details gathered from public posts. Do not rely on spelling errors as the test. When a message asks you to sign in, verify a payment, or fix an account, open the official app or type the service’s address yourself. Check the full domain before entering credentials; a padlock alone does not prove a site is genuine.
6. Verify urgent or unusual requests through another channel. A voice that sounds like a colleague or relative can be imitated or spoofed. If a request involves money, passwords, codes, confidential files, or changing payment details, pause and contact the person using a number or contact method you already trust. Do not use the number or link supplied in the suspicious message. Agree on a simple verification phrase with close contacts if that suits your circumstances.
7. Limit exposure and keep devices updated. Avoid posting details that could help someone tailor a convincing message, such as travel plans or internal work information. Install operating-system, browser, and app updates through their normal settings. Use a screen lock, and avoid signing in to sensitive accounts on shared devices. If you must use one, sign out afterward and do not save credentials.
8. Review sessions and connected apps. In important accounts, check the list of devices, active sessions, forwarding rules, and apps with account access. Remove unfamiliar sessions or integrations and revoke permissions you no longer need. For email, check that messages are not being forwarded to an address you did not set. Repeat these checks after any suspicious alert.
9. Report suspicious messages and act quickly if you interacted. Use the service’s report-phishing option or your organization’s security reporting process. If you entered a password on a questionable page, visit the real service directly from a trusted device, change that password and any reused passwords, revoke unknown sessions, and review recovery settings. If you shared a one-time code or approved a prompt, contact the service’s official support promptly and secure the account. Tell your workplace security team if work credentials or data may be involved.

Common Mistakes

• Trusting a message because it sounds right. AI can produce polished, personalized language. Judge the request and verify it independently rather than judging its grammar.
• Clicking a link to check whether a warning is real. A link can lead to a lookalike sign-in page. Navigate to the service yourself instead.
• Reusing passwords or relying only on SMS codes. Reuse lets one stolen password unlock other accounts; SMS may be less resistant to takeover than passkeys, security keys, or authenticator apps.
• Sharing a code or accepting an unexpected prompt. A caller may claim it is needed to stop fraud. Treat codes as private and reject sign-in requests you did not initiate.
• Ignoring recovery settings and sessions. A strong password cannot help if an attacker has added a recovery method or remains signed in on an unknown device.

Tips

• Prioritize accounts that can reset others: primary email, mobile-provider account, password manager, and identity or cloud accounts.
• Use a password manager’s alerts to find reused or known-exposed passwords, then change them at the real service.
• Turn on account activity notifications where available, and investigate alerts by opening the official app or site independently.
• For work, follow your organization’s reporting and verification process. Do not forward suspicious attachments to coworkers as a warning.
• Keep a written, offline record of where recovery codes are stored, but do not leave the codes where visitors or other device users can access them.

Troubleshooting

You cannot access the account: Use the service’s official account-recovery page, reached by typing its address or opening its app. Follow its identity checks. If you suspect your email or phone account was taken over, secure that account as well. Avoid anyone offering recovery in exchange for your password or code.

You lost your authenticator or security key: Use a saved recovery code or the provider’s documented recovery process. A backup method is useful only if it is also secure. After regaining access, remove the lost method, add a replacement, generate fresh recovery codes, and review active sessions.

You clicked but did not enter information: Close the page without downloading files or approving prompts. Update your browser and device, run the security scan provided by your operating system or security software, and watch for unusual account activity. If a file was downloaded or opened, disconnect the device from the network if you suspect it is compromised and contact a trusted IT support person.

You entered a password, code, or payment details: Act from a trusted device and go directly to the legitimate service. Change the password, revoke sessions, check recovery settings, and enable MFA. If you reused that password, change it everywhere it was used. Contact the relevant service or your organization’s security team; if payment information was involved, contact the payment provider using its official contact route.

Frequently Asked Questions

How can I tell whether a message was written by AI?
There is no dependable way to identify every AI-written message from its wording. Treat unexpected requests as unverified and check them through a separate, trusted channel.

Are passkeys safer than passwords?
Passkeys can resist fake login pages because they are tied to the legitimate site or app. Availability and recovery options vary, so keep your devices and account recovery methods secure.

Is an authenticator app enough?
It adds a useful layer, but it does not make every scam harmless. Never enter codes into a page opened from a suspicious message, and prefer passkeys or security keys when practical.

Should I answer a suspicious message to test the sender?
No. Replying can confirm that your address or number is active. Report it through the service or workplace process, then delete or block it if appropriate.

What if I approved a sign-in prompt by mistake?
Open the service directly, change your password, revoke unknown sessions, check recovery details, and contact official support. Secure any other account that used the same password.

How often should I review account security?
Review key settings periodically and whenever you receive an unexpected security alert, lose a device, change recovery details, or suspect a message was a scam.
