Could your employees be letting cybercriminals into your business without even realizing it?
A new type of cyberattack is targeting businesses by exploiting something most employees trust every day: IT support.
In late June 2026, security researchers identified attacks involving cybercriminals impersonating IT support personnel through Microsoft Teams. Their goal? Convince employees to install malicious software that can give attackers access to company systems and potentially lead to ransomware, data theft, and costly business disruptions.
The alarming part is that these attacks don’t necessarily require hackers to break through your firewall or defeat your security software. Instead, they exploit the trust your employees place in someone who claims to be there to help.
For small and midsize businesses, this is a serious reminder that cybersecurity requires more than technology alone.
How the IT Support Impersonation Attack Works
The process is surprisingly simple:
Step 1: The Impersonation
An employee receives a message from someone claiming to be IT support. The person may report an email problem, a spam-filter issue, or another technical concern that needs immediate attention.
Step 2: The Convincing Request
The supposed technician directs the employee to an official-looking webpage and instructs them to install a tool, browser extension, or software update.
Step 3: The Compromise
The employee follows the instructions, unknowingly allowing malicious software onto their computer.
Step 4: The Potential Damage
Attackers may then attempt to steal credentials, access sensitive information, move through the network, or deploy ransomware.
The employee isn’t necessarily careless or poorly trained. The request arrives through a familiar business communication tool, sounds legitimate, and appears to solve a real problem. When someone believes they’re following instructions from IT, complying can feel like the responsible thing to do.
That’s precisely what makes this type of social engineering so effective.
Why Your Business Should Pay Attention
For an SMB, a successful cyberattack can have consequences far beyond a single infected computer.
Operational Downtime
Employees may be unable to access email, applications, files, or critical business systems.
Financial Losses
Recovery expenses, incident response services, lost productivity, and potential ransom demands can add up quickly.
Data Exposure
Customer records, employee information, financial documents, and confidential business data may be at risk.
Reputational Damage
Customers and business partners may lose confidence if their information is compromised.
Compliance Concerns
Depending on your industry and the information involved, a security incident could trigger contractual, regulatory, or notification obligations.
Many smaller businesses assume they’re unlikely targets because they aren’t large enterprises. Unfortunately, cybercriminals often look for opportunities where employees have broad access to company systems but security procedures may be less formalized.
Three Steps to Protect Your Business From IT Support Scams
The good news is that a few straightforward practices can help reduce the risk.
1. Establish a Trusted Verification Process
Give employees a clear, reliable way to confirm that an IT support request is genuine. This could be a known support phone number, an established help desk, or a verification procedure communicated through a trusted channel.
If someone contacts an employee unexpectedly, the employee should independently verify the request before taking action.
2. Make Software Installation a Controlled Process
Employees should never install a browser extension, remote-access tool, or other software simply because someone requested it in a chat or email. Establish a policy requiring approval through your authorized IT support process.
Where possible, use technical controls to restrict unauthorized installations and limit administrative privileges.
3. Prepare Employees to Recognize Suspicious Requests
Train your team to question unexpected requests involving software installations, password resets, multifactor authentication, or remote access. Urgency, unfamiliar support contacts, and unusual instructions should prompt verification—not immediate action.
Make it clear that employees will be supported for reporting suspicious activity, even when they’re unsure whether something is legitimate.

Employee awareness is important, but it shouldn’t be your only line of defense. Effective protection combines people, processes, and technology.
