Analyze Hard-to-Identify Domains
What is Look-alike Domain?
A look-alike domain (or similar domain) refers to a domain that closely resembles the original domain, either in its form or spelling. Such similar domains are often used in impersonation (spoofing) and phishing attacks. Attackers commonly create domains that mimic trusted companies, brands, or websites and use them to send emails or set up webpages in an attempt to gain the user’s trust. Using these similar domains increases the likelihood that users may fall into malicious activities without receiving warnings.
For example, if the original domain is “example.com,” an attacker might create a similar domain like “examp1e.com” or “exarnple.com” with similar spellings to send phishing emails. When users receive such emails, it can be challenging to detect the differences from the original domain, making them vulnerable to potential harm.
Attack Pathways of Look-alike Domain
Domain Creation
The attacker creates a new domain that closely resembles the original domain. This new domain appears similar to the original one but may include slight modifications or a mixture of upper and lower-case characters to maintain similarity.
Domain Registration
The attacker registers the created look-alike domain. During this process, the attacker may use fake or anonymous information to obtain domain registration.
Email Composition
Using the created domain, the attacker composes phishing emails. These emails are designed to closely mimic the original domain in terms of domain address, logos, signatures, and other elements to emphasize the similarity with the genuine domain.
Mass Distribution
The attacker sends out the phishing emails in bulk. The content of these emails typically aims to lure users into taking action, such as visiting a phishing site or clicking on malicious links.
Phishing Attempt
Some email recipients may receive the phishing email, trust its content, and follow instructions, which can lead them to visit a phishing site or click on malicious links. This allows the attacker to collect sensitive information or prompt the download of malicious software.
Detect domains hard to identify with human eyes using ReceiveGUARD!
Emails using visually similar domains that are difficult to distinguish with the human eye are a type of phishing email designed to trick individuals and organizations into revealing sensitive information. ReceiveGUARD employs machine learning technology based on data from businesses and individual users to identify email domains that mimic those of trusted partners or entities. This proactive approach helps safeguard internal email communications, protect sensitive information, and preserve the integrity of business relationships.
