Protect your bank, email and social-media accounts as if every text, caller ID, voice, video, profile photo and search result could be forged. Use a different long password for every account, enable phishing-resistant multifactor authentication (MFA) where available, and reach sign-in pages through a bookmark, password-manager launch or the service’s known app—not an advertisement or unsolicited link. Never disclose a one-time code. When a request is urgent, verify it through a previously trusted phone number or channel, even if the caller sounds exactly like someone you know.
AI makes impersonation and phishing more convincing and cheaper to produce, but it does not defeat these controls when you verify the transaction independently. Keep public voice and image samples to a minimum, monitor account activity, and start the recovery steps immediately if a password, session or MFA code may have been exposed.
Why are AI-powered scams harder to recognize?
Generative AI lets criminals create believable text, images, audio, video, fake profiles, fraudulent websites and chatbots at scale. The FBI’s Internet Crime Complaint Center (IC3) says this increases the believability of fraud and can remove the spelling and grammar mistakes that once exposed a phishing message. Its December 3, 2024 alert states: "The FBI is warning the public that criminals exploit generative artificial intelligence (AI) to commit fraud on a larger scale which increases the believability of their schemes." Read the IC3 alert on criminals using generative AI.
The same problem affects every communication layer. A criminal can clone a short voice sample, generate a convincing video call, copy a relative’s profile picture, or place a fake login page in a search advertisement. The Commodity Futures Trading Commission describes scams using fake images, voices, videos, livestream chats, profiles and malicious financial websites in its March 19, 2025 advisory on fraud using generative AI. FinCEN has warned that deepfake media is appearing in phishing, business-email compromise, spear phishing, romance scams and investment fraud, including impersonations of family members and executives; see its November 13, 2024 deepfake-media alert.

Visual or linguistic quality is therefore not authentication. A polished message can still be malicious, and an awkward message can be genuine. The reliable test is whether the request survives an independent check using a contact route you already trust.
Which accounts and scams need the most attention?
Secure accounts in order of the damage a takeover could cause. Start with your primary email because it can reset many other accounts, then protect banking and payment accounts, cloud storage, mobile-carrier accounts, work systems, password-manager vaults and social profiles used for identity or business.
| Scam pattern | What the attacker wants | Safer response |
|---|---|---|
| Fake bank or payment support | Your password, card details, one-time code or remote access | End the contact. Call the number printed on your card or shown on the institution’s known website. |
| AI voice message from a relative or executive | An urgent transfer, gift card purchase, password or sensitive document | Use a previously confirmed number or in-person conversation. A family secret phrase can help with emergencies. |
| Search-ad or social-media login page | Your username, password and MFA code | Open a bookmark, password-manager launch or official app instead of the link. |
| Investment or romance profile with synthetic media | Money, cryptocurrency, identity documents or account access | Do not send funds or documents based on a profile, video or livestream. Verify the person and opportunity through independent records. |
| Executive or supplier impersonation | A wire transfer, payroll change or confidential file | Follow your organization’s approval process and confirm the change through a known internal channel. |
The scale is measurable even though no single statistic captures every AI-enabled account scam. An FBI alert dated November 25, 2025 reports more than 5,100 complaints and losses exceeding $262 million received by IC3 since January 2025 in an account-takeover campaign involving impersonated financial-institution support. Those figures are complaints and reported losses, not a prevalence rate for all AI scams.

Use a unique, randomly generated password for every account. A password manager can generate and store those credentials, but it does not replace MFA or protect you if you approve a fraudulent sign-in.
Start with the email account that resets everything
- Change the email password to a long, randomly generated value that has never been used elsewhere.
- Review the account’s recovery email addresses, phone numbers, forwarding rules, app passwords and signed-in sessions. Remove anything you do not recognize.
- Enable security notifications for new devices, password changes and recovery changes.
- Repeat the process for your bank, mobile carrier, cloud storage, password manager and social accounts.
Check for reuse and exposed sessions
Search your password manager for duplicate entries and replace every reused password, starting with accounts that can move money or reset other logins. Sign out of all other sessions after a suspected exposure; changing a password alone may not invalidate an attacker’s existing session cookie. Do not paste passwords into unsolicited forms, support chats or remote-access windows.

Which MFA method gives the strongest protection?
Turn on MFA everywhere possible and prefer a phishing-resistant method for high-value accounts. CISA recommends phishing-resistant MFA and passwordless MFA using a cryptographic key; a FIDO2 security key is a practical implementation when the service supports it. A key signs a challenge for the legitimate website, so a fake page cannot simply relay a one-time code.
| Method | Phishing resistance | Device or key binding | Recovery considerations | Compatibility and verification |
|---|---|---|---|---|
| FIDO2 security key | High when correctly enrolled; the origin is checked cryptographically | Dedicated hardware key | Register a second key and store it safely; use the service’s documented recovery process if both are lost | Requires account support and a compatible USB, NFC or Bluetooth connection; confirm enrollment in the account’s security settings |
| Passkey | High when created through the operating system or password manager | Cryptographic credential on approved devices, often synchronized by the platform | Recovery depends on the platform account and enrolled devices; keep a backup method | Support varies by account and device; verify the passkey appears in the official security page |
| Authenticator-app code | Moderate; a code can be typed into a convincing fake site | Secret seeded to an authenticator app | Save the service’s recovery codes offline and plan for a lost phone | Widely supported; enrollment should be done from the official account settings |
| SMS code | Lower; vulnerable to phishing and some phone-number takeover attacks | Bound to the mobile number, not the specific login page | Requires control of the number; ask the carrier about a transfer or port-out lock | Broad compatibility but weaker protection; replace with a stronger method when offered |
| Email code | Depends on the security of the email account and remains phishable | Bound to email access | Protect the email account first and keep alternate recovery options current | Common fallback, not an ideal primary factor for sensitive accounts |
Never surrender a one-time code
A legitimate bank, platform or support representative will not need you to read a one-time code to prove your identity. Enter codes only into the account page you opened yourself. If a caller asks for a code, end the call and contact the organization through its official number. The FBI’s spoofing and phishing guidance explains why caller ID and message appearance cannot establish identity.

Download or print recovery codes when an account provides them, and store them offline in a secure place. Register a spare security key or another approved factor before traveling. Make sure a trusted person knows how to reach you, but never give anyone your password or recovery codes.
How should I reach a login page safely?
Navigate directly rather than following a link supplied in an unexpected message. The FBI has warned about search-engine-optimization (SEO) poisoning, in which advertisements or manipulated results lead to convincing fake login pages; its account-takeover alert describes this technique.
- Open the organization’s known mobile app or type a saved address yourself.
- Use a browser bookmark created during a normal, verified visit, or launch the site from your password manager.
- Check the domain before entering credentials. A padlock only indicates an encrypted connection, not that the organization is genuine.
- Stop if the page asks for an unusual download, remote-control tool, gift card, cryptocurrency payment or repeated MFA approvals.
- Report the advertisement, message or page through the organization’s official abuse channel, then close it.
How can I verify an urgent request from a real person?
Use out-of-band verification: a separate channel that the requester did not initiate. Hang up on a supposed bank employee and call the number on the back of your card. If a known person writes from a new number or platform, contact them at the previously confirmed number or meet them in person. Do not use a phone number, link or email address contained in the suspicious message.

Agree on a family or team secret
Choose a short phrase in advance for emergencies, and do not publish it or reuse it as a password. If a caller cannot provide it, delay the transaction until you verify through another route. For workplaces, require a second approver and a known callback for payment, payroll or bank-detail changes.
Do these 3 things before closing this tab:

AI scams exploit urgency, secrecy and fear. A genuine emergency still allows you to say that you will call back. Treat requests to bypass normal controls, keep a conversation secret, or act while someone stays on the line as a warning sign.
How do I tell whether a voice message or video is fake?
Look for clues, but never treat them as proof. The FBI notes that AI-generated material can be difficult to identify, and modern systems may correct earlier visual and audio glitches.
- Video: Watch for distorted hands, teeth, eyes, jewelry, shadows, reflections, watermarks, lip-sync drift, unnatural movement or abrupt changes in lighting.
- Audio: Notice odd breathing, robotic timing, unusual emphasis, background noise that does not fit the setting, or a voice that responds poorly to unexpected questions.
- Conversation: Be wary of a new account, a request to move to another platform, refusal to answer personal questions, or pressure to keep the exchange secret.
- Context: Check whether the person could realistically be where they claim, whether the request matches their normal behavior, and whether the payment destination has changed.
Ask an unexpected, harmless question and then verify through a separate channel. Do not rely on asking the caller to repeat a phrase; cloning systems can reproduce it. Independent verification—not image quality, accent or emotional realism—is the deciding control.
How can I reduce the material scammers can clone?
Make social profiles private where practical and review old public posts. Limit long, clear recordings of your voice, family members’ faces, home interiors, travel plans and workplace details. Remove public phone numbers, personal email addresses, birth dates and answers to common security questions.

Privacy settings cannot erase material already copied. Ask friends and relatives not to tag you in public posts, and avoid livestreaming sensitive meetings. Before posting a photo, consider whether it reveals an ID card, boarding pass, address, school uniform or security badge that could support a later impersonation.
How should I monitor accounts for signs of takeover?
Turn on every alert your bank, card issuer, email provider and social platform offers. Check activity rather than dismissing notifications as spam.
- Look for missing deposits, unfamiliar withdrawals, new payees, changed transfer limits and small test charges.
- Review password-reset notices, new-device alerts, recovery-setting changes and unfamiliar sessions.
- Inspect email forwarding rules and social-account messages for conversations you did not start.
- Check your mobile account for a new SIM, eSIM or port-out request.
- Keep a dated record of alerts so you can identify the first unauthorized event.
Monitoring choices differ in speed, coverage and remediation. Compare them on the accounts and identities covered, how quickly an alert arrives, whether a specialist helps with recovery, how long data is retained and the total recurring cost. The official guidance does not endorse a particular monitoring vendor; your bank’s built-in alerts are often the fastest way to see a transaction, while broader identity services may cover additional records.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should I do if a scammer gets my password or MFA code?
Act immediately, even if you do not yet see a fraudulent transaction. Fast containment can prevent an attacker from changing recovery details or moving money.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Call the financial institution. Use the number on your card or its known website. Ask it to secure the account, stop transfers, and request a recall or reversal for unauthorized transactions.
- Change the exposed credential. Use a clean device if malware or remote access may be involved. Change every account where that password was reused, starting with email and your password manager.
- Revoke access. Sign out other sessions, remove unknown devices and app passwords, delete unfamiliar forwarding rules, and reset recovery email addresses or phone numbers.
- Replace the MFA factor. If a code or authenticator seed was exposed, remove it and enroll a new factor. Generate fresh recovery codes.
- Preserve evidence. Keep messages, caller numbers, email headers, URLs, transaction IDs, screenshots and downloaded files. Do not edit or forward suspicious files unnecessarily.
- Notify the impersonated organization. Use its fraud or abuse channel so it can warn other customers and preserve relevant logs.
- Report the incident. File a detailed report with the FBI Internet Crime Complaint Center account-takeover page. Use terms such as "account takeover" or "SEO poisoning" when they describe what happened.
If your phone number was hijacked, contact the carrier from another phone and ask it to restore control, add a port-out lock and document the case. If an attacker accessed work data, tell your employer’s security team immediately; do not investigate by deleting logs or wiping a company device.

What mistakes make otherwise strong defenses fail?
- Trusting caller ID: Numbers and names can be spoofed. Use a known callback route.
- Approving repeated MFA prompts: Unexpected prompts may mean someone already has your password. Deny them, change the password and report the attempt.
- Using SMS as the only factor for critical accounts: Move to a security key or passkey where supported.
- Clicking a sponsored search result: Open a bookmark or the official app instead.
- Believing a video proves identity: Verify the request independently.
- Keeping recovery information outdated: Review it after changing phone numbers, email addresses or devices.
- Waiting to report: Banks and platforms have more options before funds are withdrawn or sessions are converted into permanent access.
How should a small business or family make these controls routine?
Write a one-page rule set: no one shares MFA codes; payment or payroll changes require a callback; urgent requests are verified through a second channel; and incidents are reported immediately. Practice the callback process with a harmless example so people know which number and approval path to use under pressure.
For shared finances, assign separate user accounts instead of sharing one password, require transaction alerts for every authorized user and keep an offline list of the institution’s official contact numbers. For children and older relatives, enable automatic updates, private-by-default profiles and a trusted-contact plan that makes it easy to pause a suspicious conversation without embarrassment.
What do official agencies recommend about phishing?
NIST advises taking a second or third look at any message that asks you to click a link, download a file, transfer funds, log in or submit sensitive information. Its phishing guidance says that super-intelligent systems can craft increasingly convincing attacks. The practical implication is simple: do not make the message itself your proof. Verify the destination, the person and the requested action separately.

The IC3 social-engineering advisory and the CISA ransomware guide reinforce layered defenses: strong unique credentials, MFA, careful handling of links and files, least-privilege access, backups and a rehearsed response. AI changes the realism and scale of deception; it does not remove the value of slowing down, checking through a trusted channel and limiting what one compromised account can reach.
Frequently Asked Questions
Can AI-generated voices bypass two-factor authentication?
A cloned voice cannot directly defeat a properly implemented security key or passkey, because those methods verify the website cryptographically. It can still persuade you to reveal a code, approve a login prompt or transfer money, so treat voice identity and account authentication as separate questions.
Should I delete my social-media accounts to avoid deepfakes?
Deletion is not required for most people. Set profiles to private, remove unnecessary public recordings and photos, limit tagging, and assume anything previously public may already have been copied.
What if I clicked a fake login link but did not submit anything?
Close the page, clear any downloaded files, update the device and run its built-in security scan. Check the account for unexpected sign-in prompts; if you entered a password, change it immediately from the official app or a trusted bookmark and revoke other sessions.
Are paid identity-monitoring services necessary after an AI scam?
They are optional and vary in alert speed, coverage, support, retention practices and cost. Start with your bank, card issuer, email provider and carrier alerts, then decide whether broader monitoring fills a specific gap in the identities or accounts you need watched.
