Technology is a double-edged sword. When used correctly, it can result in cutting-edge solutions and digitization. Its misuse, on the other hand, can wreak havoc. As people and organizations become increasingly dependent on technology, it is crucial to be aware of cybercrime trends and potential risks. Only then can we ensure fortified protection against these threats. As businesses expand their digital footprints on communication and social platforms, cybercriminals also find novel ways to infiltrate and swindle them with impersonation attacks. With phishing attacks, a cybercriminal poses as a person or company to gain unauthorized access to sensitive information.

Types of Impersonation Attacks

Impersonation attacks can be implemented on several communication platforms, including social media, email, websites, SMS, voicemail, and even the phone. They can also involve misleading targets with scams executed through spoofed domains, fake mobile apps, phony social media accounts, and so on.

Email Impersonation and Spoofing

Cybercriminals send an estimated 3.4 billion emails daily, designed to look like they come from trusted senders. That’s not all: Email impersonation makes up an estimated 1.2% of all email traffic globally. Email impersonation occurs when cyber attackers create emails that seem to originate from a legitimate source by imitating the sender’s name, address, and writing style. In email spoofing, the header is forged. The goal is to make the email look as authentic as possible to convince the receiver that it’s from a trusted source or a reputable organization.

Executive Impersonation (CEO Fraud)

As the name suggests, this is business email compromise (BEC), in which criminals pose as high-authority executives of reputable organizations. They send emails to employees with urgent requests for money or sensitive information, using the combination of urgency and authority to pressure the receiver to comply without authenticating the request.

Account Takeover (ATO)

In this case, attackers gain unauthorized access to a legitimate user account, usually through phishing or credential theft. They then send emails to other people from this account, making the communication appear authentic. These emails typically ask receivers for sensitive information or initiate fraudulent monetary transactions. Because the emails are thought to come from a reliable source, receivers tend to comply and get defrauded.

Social Media Impersonation

Cybercriminals set up fraudulent accounts to impersonate high-ranking executives employed by well-known businesses or financial institutions. These phony social media accounts can defraud people, steal confidential data, or manipulate victims into giving away their credentials to unlock secure systems. This can ruin the executive’s and company’s credibility and cause severe reputational damage.

Voice and Video Impersonation

Approximately 70% of people say they aren’t confident they can tell the difference between a real and cloned voice. No wonder cybercriminals are exploiting generative AI to clone voices and produce images/videos to scam others! This is done by creating short audio and video clips using content obtained from public sources or social media. The final goal of voice and video impersonation is to gain access to private information or secure systems.

Prevention Strategies

Alarmed? We won’t be surprised. Mentioned ahead are a few effective ways to protect individuals and organizations from becoming victims of impersonation attacks.

Human Firewalls

Educating people and spreading awareness about the perils of impersonation attacks can help curtail them to some extent. This means conducting regular training sessions that focus on ways to identify suspicious requests, their verification, and best practices for using sensitive data.

Employees should know how to be vigilant and examine email addresses closely before opening them, clicking on links, or downloading malicious attachments. Organizations looking to thwart impersonation attacks must be mindful of the following:

• Avoid any emails that contain suspicious attachments
• Report unusual transaction requests, like making huge wire transfers or buying gift cards in bulk
• Flag any email received from strange locations, especially if it comes at an unusual time of the day
• Report requests for financial details or identification
• Filter emails from unknown addresses and senders

Together, these practices help create a human firewall where employees become well-equipped defenders against cybersecurity risks. As the last line of defense against cyber threats, your company’s human firewall will proactively check for potential attacks or malicious emails and report suspicious activities to the concerned authorities before the situation spirals.

Website Verification

Cybercriminals are now setting up fake websites that closely resemble those of reputed companies in design and name. These fake websites are actually phishing websites created to steal a user’s login credentials or credit card information. While there’s no way to prevent this kind of website spoofing, organizations can still take necessary steps to safeguard themselves and their customers.

Companies must set up alerts for newly registered domain names that are similar to theirs. Website verification can help here. Real-time monitoring of spoofed websites is key. Organizations can leverage AI-based threat intelligence solutions that scan the internet for domain name spoofing and website cloning. Once detected, they alert companies to take immediate action against them.

A tool like Memcyco, for instance, that provides real-time protection against impersonation attacks, can alert organizations when their website is spoofed and issue red alerts to visitors. These warnings will continue until the phony website is taken down. This simple step can ensure that companies preserve their reputation and security while retaining the faith of potential customers.

Advanced Email Security

Advanced email security solutions use machine learning algorithms to identify phishing attempts. They harness real-time threat intelligence to detect and block malicious emails and use sandboxing to evaluate suspicious attachments.

Organizations can use anti-impersonation techniques like DNS (Domain Name Server) authentication, which are equipped with protocols such as:

• DMARC (Domain-based Message Authentication, Reporting, and Conformance)
• DKIM (Domain Keys Identified Mail)
• SPF (Sender Policy Framework)

These protocols can detect and mitigate phishing attempts while blocking spoofed email addresses.

Monitoring and Quick Response

One of the most effective ways of preventing impersonation attacks is by leveraging machine learning tools that aid constant monitoring for unusual activities. A swift incident response plan should be the natural next step. This includes eliminating any fraudulent infrastructure mimicking your business.

Continuous monitoring will help you locate the impersonation and submit a takedown request to the concerned website host or social media platforms.

You can also proactively destroy attempts to create spoofed domains, fake social media accounts, or even fraudulent apps before the impersonation attack can reach your employees and/or customers.

Secure Communication Practices

Following secure communication practices involve double-checking website names, social media handles, and email addresses, especially if you suspect something.

• Verify the sender’s identity before responding to any unusual requests for information.
• Type URLs directly into the web browser’s address bar instead of clicking on an email link.
• Double-check the destination URL before clicking on an embedded link.

If you’re unsure about an email’s authenticity or detect any suspicious activity, report it to your company’s IT department immediately.

Wrapping Up

As you can see, technological innovations can be both a boon and a bane, like impersonation attacks. Fortunately, companies and individuals can take preventative and remediation actions to avoid becoming victims and curb their losses. Hopefully, this post will help you understand, identify, and avoid malicious attacks, safeguarding your organization’s reputation and credibility among customers.
