Steps to Mitigate the Potential Risks Associated with Compressed URLs
A compressed URL is simply a web address that has been shortened. These shortened web links are often created through services like Bitly, TinyURL, and Ow.ly, and they offer a practical solution for sharing long and complex web addresses.
While this feature looks excellent and convenient, it also poses potential risks because it obfuscates a link’s true destination, making it easier for cybercriminals to deceive unsuspecting users into clicking on malicious links.
The European Union Agency for Cybersecurity (ENISA) published its list of the top ten (10) cybersecurity threats for 2030, with ‘Advanced disinformation campaigns’ in second place. This also emphasizes the importance of preventing related risks.
This blog article will examine some risks associated with compressed URLs, how they could be identified, and some best practices for mitigating them.
Potential risks associated with compressed URLs
Risk is the likelihood of a threat agent exploiting a vulnerability to create a security attack. Therefore, to ensure online safety, it is essential to understand the risks associated with compressed links. These risks include;
Misdirection and Phishing
Malicious actors or cyber attackers can exploit compressed links to reroute users to harmful websites. They often use this technique in phishing attacks, where they illicitly mimic legitimate websites to obtain sensitive information, like login credentials.
For example, a cybercriminal might send an email message with a compressed link resembling one from a bank or a reputable source. However, once the recipient clicks on the link, they are redirected to a counterfeit website that prompts them to input their login information.
One way banks and other payment card industries protect the security of their users is by complying with PCI DSS requirements.
Malware Distribution
Shortened URLs have the potential to conceal links to websites that distribute malware. Users might unknowingly download malicious software or fall prey to drive-by downloads, resulting in compromised devices and data breaches.
A recent study by SpringerLink shows that Twitter’s 280-character restriction and automatic URL compression make the network particularly susceptible to the propagation of malware involved in drive-by download attacks.
Cybercriminals or malware actors were able to exploit this vulnerability to distribute malware to unsuspecting users.

Loss of Trust and Credibility
Another security risk exists if users encounter short URLs that seem suspicious or deceptive, they can undermine trust in the sender or the platform where the link was posted. This can negatively impact the reputation of businesses, organizations, or individuals.
An organization can also lose its reputation if, for instance, one of its employees clicks a malicious link that guides them to breach their privacy and security policies or mishandle a customer’s personal information.
Noncompliance
A compressed URL attack can also lead to noncompliance. If it leads a victim to violate the organization’s policy or a regulatory body, they may face disciplinary actions.

Identifying Security Vulnerabilities in Compressed Web Links
Identifying potential security vulnerabilities associated with compressed URLs is crucial to stay ahead of the attacker. Here are some methods to identify them;
Hover over the shortened URL
Before clicking the link, hover over the shortened URL to preview the complete destination. This precautionary step can help prevent falling victim to phishing or being redirected to malicious websites.
Use a reliable URL Checker tool
Utilizing a trustworthy URL checker tool to assess the safety of any shortened URL is an effective method for identifying a potentially malicious link.
A reliable URL checker can examine the link and thoroughly report its security status.
Recognizing Typical Indicators of Phishing Attempts
Recognizing the common signs of phishing attempts, such as requests for personal data, login credentials, credit card information, grammatical errors, and a sense of urgency, enables individuals to identify and avoid potential security risks linked to compressed URLs.
Exercise self-awareness when dealing with unfamiliar sources
Be cautious when clicking on shortened URLs from unfamiliar or suspicious sources, mainly if they come unexpectedly or through unsolicited messages. Always verify the source and context of the link before opening it.
How to mitigate the risks of a potential compressed URL attack
Here are some recommendations that can help prevent a compressed URL attack;
Opt for trustworthy URL-shortening services
Trust is crucial, Opting for a trustworthy URL-shortening service is one of the best ways to mitigate the potential risks associated with compressed URLs.
You can explore reputable URL shortening services like Bit.ly, TinyURL, or Rebrandly is advisable. These services incorporate security-by-design measures to identify and thwart attackers’ attempts to conceal malicious links.
Confirm the destination of a link before clicking on it
As previously mentioned, a quick way to spot malicious links is by hovering over them to preview their destination. Additionally, specific tools can reveal the end of a link from its outset, such as URL expansion tools like CheckShortURL or GetLinkInfo.
This extra step can offer valuable insights into the destination’s safety before proceeding.
Implement link detection technologies or dependable software
In the present day, advanced technologies and software applications are available for installation that help identify the destination of a link.
A typical security browser extension or plugin can also automatically expand and preview shortened URLs, providing an additional layer of security.
Moreover, implementing logical access controls through the use of reliable security software programs can flag potentially harmful links, preventing malware infections.
If you need more clarification about a link, consider reporting it to a more experienced colleague, a help desk or IT department member, or reaching out to the relevant authorities.
Participate in information security awareness programs
Investing in personal development is a crucial strategy for continual professional improvement.
By staying informed and educating yourself, you can stay ahead of emerging trends. This proactive approach enables you, or your organization, to better recognize common phishing tactics and indicators.
Conducting a Cybersecurity Risk Assessment
Implementing cybersecurity risk management helps organizations proactively identify, prioritize, and address potential risks associated with compressed URLs.
It involves targeted security measures, enhanced awareness, and continuous monitoring to strengthen the overall cybersecurity posture.
Conclusion
In conclusion, addressing the potential risks associated with clicking on shortened links is crucial to enhance an organization’s cybersecurity stance.
With awareness of the risks, identification methods, and adherence to best practices, individuals and organizations can safely navigate the use of compressed URLs.
