In today’s digital-first world, the security perimeter of a business extends far beyond the office walls. One increasingly common tactic cybercriminals are using to exploit this fact is domain spoofing — specifically, registering domain names that closely resemble those of legitimate companies, with the intention of extorting money.
A Growing Cyber Threat
Cybercriminals have become adept at purchasing domain names that are deliberately similar to those of targeted organisations. These might involve subtle changes such as switching a letter (‘rn’ instead of ‘m’), adding a hyphen, or using alternative domain extensions (e.g. ‘.co’ instead of ‘.com’). The aim is to create a domain that, at a quick glance, looks virtually identical to the genuine one.
Once this domain is set up, attackers may use it in a number of malicious ways — sending phishing emails to employees, clients, or partners; redirecting traffic to malicious websites; or, increasingly, using it as leverage to demand money from the victim company under threat of reputational damage, impersonation, or further cyber attacks.
This practice not only poses a risk to the company’s data and finances, but also to its reputation. A convincing spoofed domain can trick even vigilant customers and staff, potentially leading to compromised credentials, unauthorised payments, or leaked confidential information.
Real-World Impact
Imagine a scenario where a business owner receives a threatening message from someone using a domain that’s nearly identical to their own. The attacker may claim to have sensitive internal documents or threaten to launch a phishing campaign unless a ransom is paid. This is no longer a hypothetical situation — it’s happening to UK businesses, large and small, with alarming frequency.
What Can Businesses Do?
- As a UK MSP, we urge all businesses to take the following steps to mitigate the risk of domain spoofing.
- Register similar domain names proactively, especially common misspellings and variations.
- Implement strong email authentication protocols such as SPF, DKIM, and DMARC to prevent fraudulent use of your domain.
- Monitor new domain registrations that resemble your own brand — many cybersecurity platforms offer this service.
- Educate employees on how to identify suspicious emails and domain names, and encourage reporting of anything unusual.
- Partner with a trusted MSP who can help monitor, detect, and respond to such threats in real time.
- Report Any Incidents Immediately
If you believe your company has been targeted by this kind of cybercriminal activity — whether you’ve received threats or discovered a spoofed domain — it’s critical to act swiftly and report it to the proper authorities.
In the UK, all suspected fraud and cyber crime should be reported to Action Fraud, the national reporting centre. Visit: https://www.actionfraud.police.uk/reporting-fraud-and… to file a report and seek further guidance.
