Brand impersonation attacks take place when an attacker assumes the identity of a trusted brand or entity to manipulate and deceive victims. These attacks make use of social engineering techniques to bypass security measures while exploiting human vulnerabilities. Some of the common forms of impersonation attacks are fraudulent phone calls, fake websites, social media scams, and phishing emails. It is important to know about the relevant brand impersonation protection tips.
Attackers tend to collect information that is publicly available from different sources, including corporate websites, social media, and other online resources, to make their impersonations highly convincing. As they pose as legitimate sources, attackers are able to trick victims into revealing sensitive information, like financial details, login credentials, or personal data, which can then be used for malicious purposes.
What is the Impact of Impersonation Attacks?
In most cases, financial losses tend to be the first & foremost impact of any impersonation attack. For brands or companies, this could imply unauthorized fund transfers, fraudulent transactions, and expensive recovery strategies.
In addition to financial effects, impersonation attacks can also cause major reputational damage to brands. Organizations might face negative publicity, lose customer loyalty, and experience a decline in overall market share.
Moreover, these attacks can lead to the exposure of sensitive information. It might further lead to regulatory and legal complications. The overall psychological effect on victims, like loss of trust and stress, can also be significant, affecting professional and personal relationships.
Common Types of Brand Impersonation Attacks
Email Impersonation Attacks
Usually, attackers come up with email addresses closely resembling those of trusted organizations. They create messages that tend to replicate the style, formatting, and tone of the legitimate party to make sure that impersonation appears more convincing. Typically, these emails contain urgent payment instructions, requests for sensitive information, and links to malicious websites.
One of the most common examples of this form of email impersonation attack is a phishing email that has been sent from a bank. This type of email might ask the recipient to verify their bank account details. The email also makes use of the bank’s logo, similar email addresses, and branding to deceive the recipient.
Cousin Domain
These attacks ask the users to register domain names that appear similar to the legitimate ones. However, they come with slight variations, including misspellings or diverse top-level domains. Typically, attackers make use of these domains to send emails that appear to be coming from trusted sources.
For instance, an attacker might register a domain like ‘microsft.com’ and send over emails to Microsoft customers. The attacker might ask them to verify their accounts or reset their passwords. The slightest difference in the domain name is easily overlooked by recipients and lead to a successful phishing attempt.
CEO Fraud or Executive Impersonation
This is a common type of BEC (Business Email Compromise) where attackers impose themselves as high-ranking executives of the organization. They send emails to employees, typically in HR or finance departments, with urgent requests for sensitive information or wire transfers.
For example, an attacker might fake the identity of a CEO while sending emails to the finance department to request an immediate transfer of funds. This type of email creates a sense of authority and urgency. Therefore, it pressurizes the recipient to abide by the request without further verifying the information.
Envelope Impersonation
These types of attacks tend to manipulate the “From” field of the email address to make it appear that the email is sent from a legitimate source. When compared with spoofing, which is easily detected with the help of email filters, envelope impersonation makes use of more advanced techniques to surpass security measures.
An attacker can consider using envelope impersonation to send an email that seems to be received from a trusted party. The attacker might ask the recipient to update the payment details. The email address is created to appear authentic. Therefore, it becomes difficult for both the recipient and the system to detect this fraud.
ATO or Account Takeover
These attacks take place when attackers have access to the account details of a legitimate user. This is typically achieved through phishing or credential theft. Once they have access to such information, they are able to send emails from the compromised account and make their communications appear quite authentic.
For instance, an attacker who has access to a corporate email account will be able to send phishing emails to other employees of the department. The attacker can initiate fraudulent transactions or request sensitive documents from the employees. As the email is known to come from a reliable source, recipients might abide by the request.
How to Prevent Brand Impersonation Attacks
In addition to understanding the concept, it is equally important to know about important brand impersonation protection tips.
Using Email Authentication Protocols
When you make use of email authentication protocols, including SPF (Sender Policy Framework), DMARC (Domain-based Message Authentication, Reporting, and Conformance), and DKIM (DomainKeys Identified Mail), you can easily verify the legitimacy of incoming emails.
Implementing Strong Authentication Methods
MFA or Multi-factor Authentication helps add an extra security layer as it asks the users to provide two or more authentication factors to access an account. This method tends to minimize the risk of unauthorized access. This is because an attacker will need more than just the password to access the account.
Providing User Training & Awareness
As a brand, it is important to educate your users about the dangers of impersonation attacks. You can organize regular training sessions that cover how to identify malicious emails, the best practices for dealing with sensitive information, and the importance of verifying unexpected requests.
You should also encourage users to scrutinize email addresses effectively, particularly for slight variations. You should make them aware that they should avoid clicking on links from unknown sources.
Conclusion
Brand impersonation attacks are a major threat nowadays that target both businesses and consumers through fake websites, deceptive emails, and fraudulent social media accounts. As cyberciminals are becoming more advanced, you should aim to protect your brand identity with the help of effective cybersecurity measures.
