Can AI Hack You? What AI-Assisted Cyberattacks Really Look Like and How to Defend

Key takeaways

• AI mostly improves existing attacks such as phishing and impersonation; it rarely invents new ones.
• Spotting bad grammar no longer works; verify the request, not the writing.
• Deepfake voice or video calls asking for money need a call-back on a known number.
• Multi-factor authentication, preferably with passkeys or app prompts, blocks most stolen-password attacks.
• Report scams quickly; speed limits the loss.

Can AI really hack you?

The honest answer is: indirectly, yes. AI tools help attackers work faster and more convincingly, but a human criminal is usually directing the attack. The phrase "AI hacked me" often describes a very good phishing message or a cloned voice, not a machine breaking in alone. Understanding this shifts your defence from "spot the robot" to "verify every unusual request".

How is AI used in attacks?

What is exaggerated?

• Fully autonomous AI that finds and exploits systems with no human involvement is far less common than headlines suggest.
• Passwords are not "cracked by AI in seconds" when they are long and unique and protected by multi-factor authentication.
• Deepfakes are real but still need a plausible story and a victim who acts under pressure.

How do you defend yourself?

1. Turn on multi-factor authentication on email, banking and social accounts, and prefer passkeys or an authenticator app to SMS.
2. Use a password manager and a different password for every account.
3. Pause on urgency. Requests for money, OTPs or gift cards are red flags whoever seems to ask.
4. Verify through a second channel: call the person on a number you already hold.
5. Never share an OTP, even with someone claiming to be your bank.
6. Keep phones and computers updated, and install apps only from official stores.
7. Limit what you share publicly, since voice and photos feed impersonation.

What should organisations do?

• Require two-person approval and call-back for payments and bank detail changes.
• Run phishing simulations and teach staff that polished writing is no proof of honesty.
• Use email authentication (SPF, DKIM, DMARC) and filtering.
• Have an incident plan and report incidents to CERT-In where required.

What if you think you were scammed?

1. Contact your bank immediately to block cards and transfers.
2. Change the passwords of affected accounts and enable multi-factor authentication.
3. Save screenshots, numbers and messages as evidence.
4. Report at cybercrime.gov.in or the national helpline, and file a police complaint if money was lost.

Common mistakes

• Trusting a message because it is well written.
• Acting on a voice call without a call-back.
• Reusing passwords across accounts.
• Delaying a report because of embarrassment.
