AI-Driven Cyber Threats: What SMEs Need to Know

Artificial intelligence is transforming cybersecurity—for both attackers and defenders. Criminals are using AI to create more convincing phishing emails, generate deepfake voices, and automate attacks at unprecedented scale. Here's what your business needs to know.

How Attackers Use AI

AI gives cybercriminals superpowers they didn't have before:

AI-Generated Phishing

No more broken English. AI writes flawless phishing emails in any language, perfectly mimicking corporate tone. It can even respond to replies in real-time, maintaining the deception.

Example: A Belgian manufacturer received a perfect Dutch email from "their supplier" requesting updated payment details. The email matched the supplier's writing style exactly—because AI analyzed their previous correspondence.

Deepfake Voice Fraud

AI can clone anyone's voice from just a few seconds of audio. Attackers call employees pretending to be executives, requesting urgent wire transfers.

Example: In 2024, a UK company lost €25 million when an employee received a call from "the CEO" requesting an urgent transfer. The voice was AI-generated from earnings call recordings.

Deepfake Video

Real-time video deepfakes are now possible. Attackers can impersonate executives in video calls, making verification by sight alone unreliable.

Example: A Hong Kong bank lost $25M when finance staff joined a video call with what appeared to be the CFO and other colleagues—all deepfakes generated in real-time.

Automated Reconnaissance

AI scrapes LinkedIn, company websites, and social media to build detailed profiles of targets. It identifies who to attack, what to say, and when to strike.

Example: AI tools can analyze your entire company org chart, identify who handles payments, find their personal social media, and craft personalized attacks—all automatically.

AI-Powered Malware

Malware that adapts to evade detection, automatically finds vulnerabilities, and optimizes its attack strategy in real-time.

Example: New malware variants use AI to understand security software and modify themselves to avoid detection, making traditional antivirus less effective.

Why AI Changes Everything

The key shift: attacks that required skill and time can now be automated.

Scale

One attacker can now run thousands of personalized campaigns simultaneously. What took weeks takes minutes.

Quality

AI-generated content is often better than human-written attacks. No spelling mistakes, perfect tone matching, culturally appropriate.

Personalization

Every target gets a unique, customized attack based on their digital footprint. Generic "Dear Sir" emails are replaced with detailed knowledge of your business.

Cost

Sophisticated attacks that only nation-states could afford are now available to any criminal with $20/month for AI tools.

Speed

AI responds instantly to victim replies, maintains conversations, and adapts tactics in real-time based on what works.

How to Defend Against AI Threats

The good news: AI attacks still have weaknesses you can exploit.

Establish verification protocols

Never authorize payments or sensitive actions based on email, voice, or video alone. Always verify through a separate, pre-established channel.

Tip: Create a "callback number" policy: for any financial request, call the requester back on a number from your contacts, not from the email or call itself.

Use code words or duress signals

Establish secret phrases that only legitimate employees know. If someone can't provide the code word, treat the request as suspicious.

Tip: Change code words quarterly. Include a "duress word" that signals someone is being coerced.

Train on AI content recognition

Employees should know that AI-generated content exists and that perfect grammar is no longer a trust signal. Encourage healthy skepticism.

Tip: Run deepfake awareness training. Show examples of AI-generated voices and videos so employees know what's possible.

Implement payment controls

Require multiple approvals for large transfers. No single person should be able to authorize significant payments.

Tip: Set thresholds: any payment over €5,000 requires verification through two channels. Any "urgent" request triggers extra scrutiny.

Limit public information

AI attacks often start with reconnaissance. The less you share publicly about internal processes, org structure, and personnel, the harder you are to target.

Tip: Audit what's on LinkedIn and your website. Do you need to publish your org chart? Do executives need to share their schedules?

Monitor for impersonation

Set up alerts for domains similar to yours, social media accounts using your company name, and mentions of executives in unusual contexts.

Tip: Use services that monitor for typosquatting domains (e.g., easyycyberprotection.com instead of easycyberprotection.com).

Red Flags for AI-Generated Attacks

Watch for these signs that you might be dealing with an AI-powered attack:

  • Perfect grammar in a language the sender wouldn't normally use fluently
  • Unusually detailed knowledge of internal processes from an external contact
  • Requests that bypass normal procedures, citing urgency
  • Voice calls where the speaker avoids open-ended questions
  • Video calls with slightly "off" lip sync or unusual lighting
  • Emails that seem to anticipate and answer your objections before you raise them
  • Communications that feel "too polished" compared to the person's normal style
  • Pressure to act immediately without time to verify

What's Coming Next

AI threats will continue to evolve. Prepare for:

Agentic AI attacks

AI systems that autonomously identify targets, craft attacks, respond to defenses, and adapt without human intervention.

Real-time translation attacks

Seamless attacks in any language, with AI handling real-time voice translation during calls.

AI vs AI

Security tools increasingly use AI to detect AI-generated threats. It becomes an arms race.

Synthetic identities

AI-generated "people" with fake social media histories, photos, and work records applying for jobs or requesting partnerships.

How Easy Cyber Protection Helps

Security awareness training — Keep your team updated on AI-powered threats with practical examples
Policy templates — Ready-to-use verification and payment authorization procedures
Incident response planning — Know exactly what to do if you suspect an AI-powered attack
Risk assessment — Identify what public information makes you vulnerable

Frequently Asked Questions

Can AI really clone someone's voice from a short clip?

Yes. Modern voice cloning AI needs only 3-10 seconds of audio to create a convincing clone. Public sources like earnings calls, YouTube videos, podcasts, or even voicemail greetings provide enough material. The technology is widely available and costs less than $20/month.

How can I tell if an email was written by AI?

It's increasingly difficult. AI-generated text has no reliable tells. Instead of trying to detect AI, focus on verifying the sender and request through independent channels. Assume any written communication could be AI-generated and verify accordingly.

Should we stop using email and phone for financial decisions?

Not necessarily, but you should never rely on a single channel. Use multi-channel verification: if you receive an email request, verify by phone using a known number. If you receive a call, verify by email to a known address. The more channels you verify through, the harder you are to fool.

Are SMEs really targeted by these sophisticated attacks?

Increasingly yes. AI makes sophisticated attacks cheap and scalable. Criminals no longer need to choose between "big targets" and "easy targets"—they can pursue both simultaneously. SMEs often have weaker security than enterprises but still process significant funds.

What should I do if I suspect I received an AI-generated attack?

Don't engage or click any links. Verify the request through a completely separate channel (call using a number from your own records, not from the suspicious message). Report it to your IT team and consider reporting to local authorities. If you've already acted on the request, contact your bank immediately.
