The Dangers of AI in the Workplace: Security Risks Employees Should Know

How AI tools create security risks

AI tools are powerful but not automatically secure. They collect and process large amounts of data, and when employees share sensitive information with them without thinking, that information can leave company control. Some AI platforms store user data to improve their systems, and others may not clearly explain how data is handled. In addition, AI-generated content can be used to mislead employees or support cyber crime.

Risk 1: Data leakage

One of the biggest security risks comes from unintentionally sharing confidential information. When employees copy and paste internal documents, customer information or source code into public AI tools, that data may be stored by the provider or used to train future AI models. Even if this is not the user’s intention, the result is the same: sensitive information leaves the organisation and may no longer be protected.

For example, someone might ask an AI tool to summarise a contract and include confidential pricing details in the prompt. Another employee might paste customer data into a chatbot to generate a support email template. In both cases, private information has now been shared with an external system.

Risk 2: AI-powered phishing attacks

Cyber criminals are using AI to create more convincing phishing emails, fake websites and even voice recordings. These messages are often well-written and free from spelling or grammar errors, which traditionally helped people spot scams.

AI can also personalise phishing messages using information found online, making them feel more believable. What used to look suspicious now appears more professional, which increases the likelihood of someone clicking a link or sharing a password.

Risk 3: Inaccurate or unsafe output

AI tools are not always right. They can produce convincing but completely false answers, a problem known as hallucination. Employees who rely on AI without checking its output risk spreading misinformation or making poor decisions based on incorrect advice. Using AI to draft legal or financial content without proper review can create serious problems. Security guidance generated by AI might also be unreliable or even harmful if followed without question.

Risk 4: Shadow IT

Shadow IT refers to the use of unauthorised tools without approval from IT or security teams. Many AI tools are easy to access, so employees start using them independently, often with good intentions. However, these tools might not meet company security standards. Without proper oversight, they can introduce vulnerabilities, store sensitive data or even expose the organisation to compliance issues.

Risk 5: Malicious AI tools

Not every AI tool online is safe. Some are fake services designed to spread malware or steal data. Criminals create imitation AI websites and browser extensions that claim to boost productivity, but instead capture passwords, install spyware or give attackers remote access. Employees may not realise the risk if they download tools from unofficial websites or app stores.

How employees can reduce AI risks

Safe use of AI starts with awareness. Employees should avoid entering confidential, personal or company-sensitive information into AI tools unless they are approved for such use. Only official, company-approved AI platforms should be used, and anything involving customer data, financial information or internal documents should be handled carefully. AI-generated output should always be reviewed and edited before sharing or using, especially for professional communication.

It also helps to understand how AI tools process data. Reading the privacy settings and terms of use can prevent accidental data exposure. If a browser extension or app claims to provide AI features, check whether it comes from a trusted source before installing it. When in doubt, ask IT before using a new tool.

Safe use of AI at work

AI can be used safely if handled correctly. The key is to treat it as a helpful assistant, not a decision-maker. Use AI for low-risk tasks such as summarising publicly available information, drafting simple content or generating ideas. Avoid sharing full documents or sensitive information in prompts. If examples are needed, replace real data with fake or anonymised information. Employees should understand that AI does not think or verify facts, so human review is always necessary.

What to do if data is shared by mistake

If sensitive information has already been entered into an AI tool by accident, act quickly. Report the incident to IT or your security team so they can assess the risk. Provide the exact text or file that was shared to determine whether it contains personal data or confidential information. Do not attempt to hide the mistake. Early reporting helps reduce potential damage and allows the company to take corrective action if necessary.

Simple checklist for employees

• Only use AI tools approved by your company
  
  

• Never enter confidential or personal data into public AI tools
  
  

• Double check AI-generated content for accuracy and safety
  
  

• Be cautious of AI-related browser extensions and apps
  
  

• Slow down and think before clicking on AI-generated links or messages
  
  

• Report suspicious AI activity or tools immediately

Conclusion

AI offers huge potential benefits, but it also opens the door to new security threats if used carelessly. The biggest risk is not the technology itself but how people use it. With a few simple habits and an understanding of how AI tools work, employees can use AI safely without putting company data at risk. Security awareness is essential in a workplace where technology continues to evolve.
