New domain extensions are garnering newfound attention from cybercriminals. What may be thought of as a touch of uniqueness, or perhaps necessity, could in fact drive up cybercrime.

Some of the newest extensions mirror well-known and widely used existing file extension types. Using these mirror-image domain extensions is problematic and opens the door to user confusion. Let’s highlight the risks posed, the potential for exploitation by hackers, and some tips to avoid falling victim yourself.

The Rising Threat: Domain Extension Confusion

We’ve all seen and grown familiar with using common domains like .com, .org, and .net.

These extensions have gained credibility and trustworthiness through extensive usage. For many, a .gov extension or .edu may hold the ultimate superiority when looking for answers to questions or guidance on a particular topic, but new domains like .mov, .zip, and others present a real problem. These new domain extensions mimic well-known file-type extensions. For instance, .mov and .zip make it easier for hackers to exploit unsuspecting users expecting an attachment instead of a hyperlink.

Exploitation Potential on Social Media Platforms

Social media platforms have become breeding grounds for cybercriminals seeking to deceive users and compromise a security system. Hackers often employ techniques like phishing and URL hijacking (also known as “clickjacking”) to manipulate users into clicking on malicious links. Deceptive domain extensions significantly enhance the success rate of such attacks.

Phishing Attacks and Malware Distribution

Phishing attacks involve tricking users into divulging sensitive information, such as passwords or credit card details, by impersonating legitimate companies or people. Hackers can create malicious websites with URLs resembling trusted domains, leveraging similar extensions to deceive users into believing they are interacting with familiar platforms.

By using domain extensions like .zip to distribute malware disguised as an expected file or document, hackers can intercept and trick users. Disguising malware within a compressed file format drives user action to extract the documents within, unknowingly downloading and executing harmful software onto their devices.

Preventive Measures and Awareness

To mitigate the risks associated with deceptive domain extensions, it is crucial for users to remain vigilant and adopt best practices:

  • Double-check URLs: Examine before clicking on a link, especially when dealing with unfamiliar domain extensions. Look for slight misspellings or inconsistencies that may indicate a deceptive website.
  • Verify website security: Ensure websites are encrypted and secure by checking for the padlock symbol and "https" in the URL. This indicates a secure connection and reduces the chances of falling victim to phishing attacks. Remember, cybercriminals can deploy scams via secure sites as well so be sure to steer clear of providing private or privileged information on any site without knowing it’s legitimate.
  • Implement robust cybersecurity measures: Use reputable antivirus software, keep operating systems and applications up to date, and regularly back up important data to protect against potential malware attacks stemming from accidental fraudulent domain clicks.
  • Stay informed: Current affairs and recent news articles or company blogs can keep you abreast of the latest cybersecurity threats and trends. Follow reputable sources and subscribe to trusted industry social media channels for in-depth information. Knowledge is a powerful tool in safeguarding company security.

Bottom Line

New domain extensions present new opportunities for business owners and associations to expand their reach and creativity. With this new expansion also comes significant security concerns and challenges.

The exploitation potential of deceptive or tricky extensions, as seen with .mov and .zip on platforms like Twitter and beyond, underscores the importance of user vigilance and awareness.
