A cyber attack has just targeted one of our clients.
A member of staff followed the instructions on what looked like a normal website verification. Without realising it, they ran a hidden command created by a cybercriminal.
The deception worked, but the attack did not.
The security and monitoring we had already put in place stopped it before it could cause any damage. Our team contained the risk, investigated what had happened and briefed the client once we knew their computer was safe.
This is a real incident. It happened recently, it could happen to a business of any size, and it shows why cyber security cannot rely on employees spotting every convincing threat.
It started with a familiar security check
The employee was taken to a website that asked them to prove they were human.
We see these checks all the time. Select the traffic lights. Tick a box. Confirm you are not a robot.
The website gave the employee a few simple instructions to follow. Those steps secretly copied and ran a hidden command.
What appeared on screen looked like an innocent verification code because the dangerous part had been hidden from view. To the employee, it looked like a familiar security check.
The instructions were the attack
This type of attack is known as ClickFix. Despite the technical name, the idea is simple. A fake message persuades someone to complete the attack without realising it.
Following the instructions tells the computer to run something harmful. That hidden command can then try to contact the cybercriminal, download harmful software or send information outside the business.
That is what it attempted to do here. Fortunately, it could not get any further.
This could happen to any business
Nothing about this attack depended on the client’s size, sector or turnover. It only needed one employee to encounter a convincing website and follow what appeared to be genuine instructions.
They could work for a family business, charity, manufacturer or national organisation. Any business with employees, computers and valuable information could face the same situation.
No business is too small to be affected. A good starting point is Cyber Essentials, which helps organisations put fundamental cyber security controls in place.
The protection was already in place
The attacker tried to misuse a powerful tool built into the employee’s computer.
Most employees would never need this tool in their day-to-day work. As part of the client’s cyber security, we had already restricted what it could do.
When the hidden command attempted to connect to the attacker’s systems, those controls blocked it. The attack could not download anything further or send information outside the business.
This protection had been put in place long before it was needed. It turned a potentially serious cyber attack into a contained near miss.
We knew before the client did
The employee did not realise they had triggered an attack, but they did not need to spot it before action could be taken.
Our security monitoring detected the unusual activity and alerted our team. We contained the risk, investigated what had happened and checked the affected computer.
Once we had confirmed that the attack had not progressed, we briefed the client with the facts. By the time they became aware of the incident, the immediate risk had already been handled.
Cyber awareness matters, but it cannot stand alone
With Cyber Security Awareness Month approaching this October, many businesses will be reminding employees how to recognise suspicious emails, websites and online requests.
The theme for 2026 is “Don’t Make It Easy for Them.”
It is a fitting message for this incident. Good cyber security is not about relying on one person to make the perfect decision every time. It is about building good habits and putting safeguards in place that make it much harder for an attacker to succeed.
Employee training remains important. Staff should understand the warning signs, know how to report a suspicious website to the NCSC and feel confident raising concerns.
But no person will spot every threat.
These attacks are designed to appear genuine, often using something familiar like a “prove you are human” check. One understandable mistake should not be enough to give a cybercriminal access to the business.
This October is an opportunity to review both employee awareness and the protection working quietly behind it.
What could have happened?
If the command had continued, it could have downloaded harmful software or opened a connection with the attacker.
The consequences could have included stolen information, disrupted systems, lost working time, ransomware, financial loss and reputational damage.
For a smaller business, even a short disruption can have a serious effect. Prevention should be the priority, but every organisation should also know what to do if a cyber attack succeeds.
Would your business be ready?
Most businesses have some sort of antivirus protection, and some may even provide awareness training. Both matter, but the real test is what happens next.
Would unusual activity be noticed? Who would investigate it? Could the attack be contained before it caused damage?
Effective cyber security accepts that mistakes happen and puts barriers in place to limit the consequences.
A Cyber Risk Assessment can identify where your business may be exposed and provide clear priorities for improvement.
As an NCSC-assured Cyber Advisor, Start Tech provides practical cyber security guidance and support to small and medium-sized organisations across the UK.
For this client, the protection we had put in place turned a potentially serious attack into a contained near miss. Would your business be ready to do the same?
