In 2026, cybercriminals are increasingly using AI to create convincing phishing emails, generate fake voices and videos, automate malicious activities, and develop more sophisticated online scams. These developments make it harder for ordinary internet users and businesses to recognize potential threats.

At the same time, cybersecurity professionals are using AI to detect suspicious activities, identify vulnerabilities, and protect sensitive information. This creates a new digital environment where both attackers and defenders benefit from artificial intelligence.

In this guide, we will explore how AI is changing cybersecurity, the seven major online threats you should know about in 2026, and practical ways to protect yourself.

What Is AI in Cybersecurity?

AI in cybersecurity refers to using artificial intelligence and machine learning technologies to identify, prevent, analyze, and respond to digital security threats.

Security professionals use AI-powered systems to monitor network activity, detect unusual login attempts, identify suspicious emails, and investigate potential cyberattacks.

However, cybercriminals can also misuse these technologies. They can generate realistic scam messages, impersonate trusted individuals, automate attacks, and search for weaknesses in digital systems.

According to Microsoft's 2026 Digital Defense Report, AI is changing the speed, scale, and automation of cyberattacks while also providing new opportunities for security professionals.

7 Major AI-Powered Cybersecurity Threats in 2026

Artificial intelligence is making several traditional cybercrime techniques more sophisticated. Here are seven important threats that individuals and businesses should understand.

1. AI-Powered Phishing Attacks

Phishing is one of the most common forms of cybercrime. It involves sending fake emails, text messages, or website links to trick people into revealing sensitive information such as passwords, banking details, or account credentials.

AI has made these attacks more convincing. Previously, phishing emails often contained spelling mistakes, poor grammar, and suspicious wording. AI tools can now generate professional-looking messages with personalized information and natural language.

For example, you might receive an email that appears to come from your bank, workplace, or an online shopping platform. The message may ask you to verify your account or update your payment information through a fake website.

Because these messages can look realistic, identifying phishing attempts has become more difficult.

How to Stay Safe:

• Never click suspicious links in unexpected emails or messages.
• Check the sender's actual email address before responding.
• Never share passwords or verification codes through unexpected requests.
• Visit official websites directly instead of following unfamiliar links.
• Enable multi-factor authentication on important accounts.

2. Deepfake Voice and Video Scams

Deepfake technology is another growing cybersecurity concern in 2026. AI can generate realistic audio and video that imitate another person's voice or appearance.

Cybercriminals can misuse this technology to impersonate family members, company executives, employees, or other trusted individuals.

Imagine receiving a phone call that sounds exactly like your manager. They urgently ask you to transfer money or share confidential business information. Although the voice sounds familiar, the person behind the call could be a criminal using AI-generated audio.

These scams can also involve fake video calls, making it harder to verify someone's identity through ordinary communication.

How to Stay Safe:

• Verify unusual financial requests through a separate communication channel.
• Confirm the identity of callers before sharing sensitive information.
• Use a private verification phrase with family members if appropriate.
• Follow company approval procedures before transferring money.
• Do not rely entirely on someone's voice or video to confirm their identity.

3. AI-Generated Malware and Automated Cyberattacks

Malware is malicious software designed to damage computer systems, steal information, or gain unauthorized access to devices and networks.

AI is helping attackers research vulnerabilities, develop malicious code, and automate certain stages of cyberattacks. Some criminals use AI to speed up technical tasks, while more advanced systems can coordinate multiple activities with less human intervention.

Google Threat Intelligence Group reported in September 2026 that some threat actors had moved beyond basic AI prompting toward agentic AI workflows and automated attack operations.

This means cybercriminals can potentially use AI systems to perform multiple connected tasks more quickly than traditional manual methods.

How to Stay Safe:

• Keep Windows, Android, iOS, and other applications updated.
• Download software only from official websites and trusted app stores.
• Use reputable antivirus and endpoint protection software.
• Avoid opening unexpected email attachments.
• Regularly back up important files and documents.

4. AI-Powered Identity Theft and Online Scams

Identity theft occurs when criminals use another person's personal information without permission. AI makes this problem more complicated because attackers can generate fake identities, profile pictures, documents, and convincing conversations.

For example, scammers may create fake social media accounts using AI-generated profile pictures. They can then contact people, build trust, and promote fraudulent investment opportunities or other scams.

AI can also help criminals produce personalized messages in different languages, allowing them to target more people.

How to Stay Safe:

• Avoid sharing sensitive personal information publicly.
• Enable two-factor authentication on important accounts.
• Verify unfamiliar social media profiles before trusting them.
• Be careful with investment offers promising guaranteed returns.
• Monitor your bank accounts and online transactions regularly.

5. AI-Powered Password and Account Attacks

Passwords remain one of the most important parts of online security. Cybercriminals use different techniques to gain access to accounts, including stolen credentials, password reuse, and automated login attempts.

AI can help attackers analyze available information and create more personalized social engineering attempts.

Another concern is session token theft. If attackers obtain valid session tokens, they may gain access to an account without entering its password again.

This means that even accounts protected by additional authentication methods can face risks if their active sessions are compromised.

How to Stay Safe:

• Use unique passwords for different websites.
• Create long and difficult-to-guess passwords.
• Use a trusted password manager.
• Enable passkeys or multi-factor authentication where available.
• Review account activity and sign out of unfamiliar sessions.

6. Attacks Against AI Chatbots and Applications

AI applications themselves are becoming targets for cybercriminals. Businesses increasingly use AI chatbots, virtual assistants, and automated agents to process information and perform tasks.

However, poorly secured AI applications may expose sensitive information or respond to malicious instructions.

One example is prompt injection. This occurs when malicious instructions are placed inside content that an AI system processes. These instructions may attempt to manipulate the system into ignoring its intended behavior or revealing information it should not disclose.

For example, a company employee might ask an AI assistant to summarize a document containing hidden malicious instructions. If the application is not properly protected, those instructions could influence its response.

The OWASP GenAI Security Project's 2026 Top 10 identifies prompt injection, sensitive information disclosure, and excessive agency among the major security risks affecting AI applications.

How to Stay Safe:

• Avoid entering passwords or confidential information into untrusted AI tools.
• Use reputable AI applications and services.
• Businesses should restrict AI access to sensitive information.
• Review application permissions regularly.
• Use security testing and monitoring for AI-powered systems.

7. AI-Driven Social Engineering Attacks

Social engineering involves manipulating people into sharing confidential information or performing actions that benefit criminals.

AI makes these attacks more convincing because scammers can create personalized messages, imitate communication styles, and generate realistic voices.

For example, a criminal might impersonate a technical support representative and contact someone about a fake account security issue. The attacker may create a sense of urgency and persuade the victim to reveal a password or verification code.

Unlike traditional hacking, social engineering often targets human trust rather than technical weaknesses.

How to Stay Safe:

• Be suspicious of unexpected urgent requests.
• Never share one-time passwords or verification codes.
• Confirm the identity of people requesting sensitive information.
• Avoid installing remote-access applications at the request of unknown callers.
• Contact organizations through their official communication channels.
