Deepfakes and AI Voice Scams

Until recently, hearing a familiar voice or seeing a face on a video call was good evidence that you were speaking to the right person. That is no longer a safe assumption. Software can now imitate voices from a few seconds of audio, generate convincing faces and produce video of people saying things they never said.

Most scams still rely on old tricks: urgency, secrecy and money. The new tools make those tricks more convincing. The defense is a habit rather than a gadget: when something important or unusual is requested, verify it through a second channel you already trust.

Technology and laws evolve quickly. This guide is general information and describes principles rather than specific tools. If you are a victim, seek help from your university, the platform and the authorities.

What the terms mean

• Deepfake: synthetic or altered audio, video or images that imitate a real person.
• Voice cloning: software that mimics someone's voice from samples.
• Face swapping: replacing one person's face with another in an image or video.
• Generated images: pictures created entirely by software, sometimes used for fake profiles.
• Shallowfake or cheapfake: simpler edits such as cropped, slowed or relabeled real media, which also mislead.

Not all synthetic media is malicious, but it can be used for fraud, harassment and misinformation.

How scammers use them against students

Cloned-voice emergency calls

You receive a call that sounds like a parent, sibling, friend or partner saying they are in trouble: arrested, in an accident, stranded abroad. They need money quickly, often by unusual means. Scammers rely on panic to stop you thinking. Students far from home, or whose relatives live abroad, are especially vulnerable.

Fake video calls

A scammer joins a call with a convincing face or recorded clip, claiming to be a recruiter, landlord, official or someone you know. They request personal data, payments or login codes.

Impersonation of lecturers, staff and institutions

Messages or calls that appear to come from a professor, finance office or IT team, sometimes with a voice message to add credibility. They ask you to transfer fees, share codes or click links.

Romance and investment scams

Fake profiles with generated photos, plus voice or video calls using synthetic media. The relationship builds trust and then leads to requests for money or investments.

Blackmail and sextortion

Offenders use manipulated images, including faces edited into intimate images, to threaten victims.

Harassment and humiliation

Fake images or clips of classmates circulated in group chats or social media. This is a serious form of bullying and in many places a crime.

Fake endorsements and misinformation

Videos of public figures promoting investments, giveaways or false claims. Scammers use them to promote fraud.

Warning signs

Synthetic media is improving, so visual and audio clues are not reliable on their own. Treat these as hints, not proof.

• Urgency and pressure. The core of most scams.
• Requests for money, gift cards, crypto or secrecy.
• Unusual communication channels, such as a new number, a different app or a call at an odd time.
• Reluctance to answer personal questions only the real person would know.
• Odd audio: flat tone, strange pauses, background noise that does not fit.
• Odd video: blurry edges, mismatched lighting, unnatural blinking, distorted hands or teeth, or lips that do not match words.
• Refusal to switch to another method of contact.
• The story does not fit what you know.
• Poor quality blamed on a bad connection.

Some fakes are very good, so do not rely on your ability to spot flaws.

Verify before you act

Make verification a routine.

1. Pause. Do not act on urgency.
2. Hang up and call back on a number you already have for the person, not one given in the call.
3. Use a second channel: message another family member, a mutual friend or the person's official account.
4. Ask a question only the real person would answer, and one that is not on social media.
5. Use a code word. Agree a secret word or phrase with close family and friends for emergencies, and do not post it online.
6. Check with the institution. For anything claiming to be from your university, a landlord or a bank, contact them via official channels.
7. Do not send money or codes until verified.
8. Report suspected scams.

Tell relatives about these scams. Older relatives are often targeted, but students can be too.

Protect your voice and images

You cannot eliminate risk, but you can reduce it.

• Limit public audio and video where practical, especially long clips of your voice.
• Review privacy settings on social media.
• Be cautious with voice notes and video messages to strangers.
• Avoid unknown callers. Do not engage with unfamiliar callers, which can be used to collect voice samples.
• Use strong account security so that real recordings are not stolen.
• Be careful about sharing photos that show your face clearly in many angles.
• Watermarking and metadata tools may help creators, though they are not foolproof.
• Respect others' images. Do not use or share synthetic media of classmates.

If you receive a suspicious call or video

• End the call and verify.
• Do not provide personal data, codes or payment.
• Note details such as the number, time and what was said.
• Block the number and report it to your provider.
• Tell your family and friends if the scam used their identity.
• Report to the police or national fraud service if money or personal data was involved.

If a fake of you appears online

1. Stay calm and save evidence: screenshots, links, usernames and dates. Do not forward the content widely.
2. Report it to the platform as impersonation, non-consensual content or harassment.
3. Use takedown tools offered by platforms and search engines, including those for non-consensual intimate imagery.
4. Tell trusted people, your university and, where appropriate, your employer or placement provider.
5. Contact the police if it involves blackmail, threats, stalking or sexual content. Laws on synthetic content are developing in many countries.
6. Seek legal advice from a student union or legal clinic if you want to pursue removal or action.
7. Look after yourself. Being targeted can be distressing. Use your university's counseling or wellbeing service.

If a fake was created by a classmate

Report it to your university's conduct office and the platform. Creating or sharing sexual deepfakes, harassment and impersonation may break university rules and the law. Do not retaliate. Preserve evidence and ask for support.

Be a careful consumer of media

• Check the source. Who posted it, and is there corroboration from reliable outlets?
• Do a reverse image or video search.
• Look for context. Is the clip edited or taken from elsewhere?
• Be skeptical of shocking content that confirms your beliefs.
• Do not share unverified media.
• Remember that real videos can be dismissed as fake, and fake ones can be believed. Verification matters either way.

Talking with family and friends

These scams work best on people who have never heard of them. Spend ten minutes explaining the pattern to the people most likely to be called in a panic: parents, grandparents and siblings. Agree the code word, a second contact number and a rule that nobody sends money after a call until they have spoken to you directly or to another family member.

Make it a normal topic, like locking the door, instead of a scary lecture. If someone does fall for a scam, respond kindly and help them report it, because shame stops people from warning others.

Common mistakes

• Trusting a voice or face alone.
• Acting on urgency.
• Calling back on a number the caller supplied.
• Posting a family code word online.
• Sharing synthetic or unverified media.
• Staying silent after being targeted.
• Skipping account security.

A quick checklist

• Do my family and close friends have a code word?
• Do I verify unusual requests through a second channel?
• Are my social profiles set to limit public audio and video?
• Do I know how to report and remove fake content?
• Have I secured my accounts?

Final thoughts

Deepfakes and voice cloning make old scams more convincing, but the defense is still simple. Slow down, verify through a trusted second channel and refuse to pay or share codes under pressure. Limit what you post publicly, secure your accounts and know how to report and remove harmful content. A calm routine beats trying to out-detect software.
