The Hidden Dangers of Deepfake Video & Voice Calls
Imagine this:You get a video call from your boss. Their face appears. Their voice is familiar.They ask you to send over a document — or worse, approve a payment.
Would you do it?
What if I told you… that wasn’t really them?
Welcome to the world of deepfakes and deepcalls — where AI-generated voices and faces are used to deceive, manipulate, and scam.
🤖 What Are Deepfakes & Deepcalls?
Deepfake video: AI-generated faces or videos that look like a real person — talking, blinking, moving… but totally fake.
Deepfake voice (deepcall): AI mimics someone’s voice in real-time, making phone or video calls sound authentic.
🎯 Both use deep learning algorithms trained on recordings, photos, or videos of a real person.
🎯 Think this is science fiction?
Already happened:
CEO voice cloned in a fraud call → €220,000 stolen in Europe (source: [The Guardian, 2020])
Deepfake video of Zelenskyy posted online, telling Ukrainian soldiers to surrender
Scammers clone the voice of a child or relative to demand ransom or urgent help
🚨 Why Is This Dangerous?
Type of Attack | What Happens |
🎥 Fake boss call (video) | Employee sends sensitive info or money |
📞 Fake family emergency (voice) | You’re tricked into acting emotionally |
🏦 Bank call impersonation | Login credentials or transfers are stolen |
🎙️ Fake interviews or Zooms | Disinformation or infiltration |
🔍 Quick Self-Check — Would You Fall for It?
✅ Have you ever acted quickly on a phone call from a superior?
✅ Would you trust a video call based on voice and face alone?
✅ Do you verify caller identity before sending info?
If you hesitated… you’re exactly who attackers hope to target.
🔐 Expert Tips: How to Stay Safe from Deepfakes
1. Never act on voice or video alone
👉 Always verify the request through a second channel (email, SMS, or face-to-face)
2. Have a code word for emergencies
🔒 Especially in families or small teams→ If someone calls in a panic: “Say the passcode.”
3. Pause and breathe — social engineers hate silence
Fake urgency is a red flag.❗ Deepcall attacks rely on you reacting before thinking.
4. Use video filters or low-quality calls for privacy
🛑 High-res video and audio makes cloning easier→ Ironically, blurry is safer.
5. Stay informed and educate others
🧠 The best defense is awareness.Train your team. Talk to your family. Share examples.
🧠 Final Thought from a Cybersecurity Expert:
“If a face can lie and a voice can trick you… trust must come from elsewhere.”
