The Risks Behind Short Links

August 27, 2023



Short links have become ubiquitous in the online world, providing a convenient way to share lengthy URLs. Services like,, and are used to compress URLs, making them more visually appealing and suitable for platforms with character limits. However, while short links offer convenience, they also present several privacy and security threats that users should be aware of.

In this blog, we will go through how URL shorteners work, how they can be used, and the privacy and security threats they pose.

How Short Links Work


When you click on a short link, you're directed to the final destination URL. However, before reaching the intended website, the link takes a detour through a URL shortener service. This redirection is usually swift, but it provides enough time for potential electronic threats to occur.


The Motivation Behind Short Links


The primary reason for using short links is to save space and character limits, especially on platforms like social media. Unfortunately, the motivations behind creating short links aren't always user-centric. Link creators might have their own agendas, often involving tracking and marketing purposes.


User Tracking via Short Links


Long URLs can include tracking parameters (UTM tags) for monitoring click-through rates, ad campaign effectiveness, and more. While these parameters are generally harmless, shorteners are used to make URLs more concise. This action can raise privacy concerns since URL shorteners might collect additional data about users. This information becomes accessible not only to the short link creator but also to the URL shortening service.


Disguised Malicious Links


One significant risk of short links is the potential for disguised malicious links. Unlike regular URLs, where you can often discern the destination by inspecting the link, short links mask the actual target. This leaves users vulnerable to falling into cybercriminal traps, such as phishing sites or sites exploiting browser vulnerabilities.


Dynamic Redirects and Persistent Threats


Cybercriminals can exploit short links to dynamically change the target address as needed. For example, if a phishing site is detected and blocked, attackers can rehost it at a different address and modify the short link accordingly. This strategy makes it challenging to mitigate threats effectively.


Man-in-the-Middle Attacks


Certain shortening services enable man-in-the-middle attacks by tracking link clicker activities on the destination site. This approach allows the shortening service to intercept and potentially misuse exchanged data, including sensitive information like credentials.


Personal Spying and Doxing


While short links are commonly found on social media and websites, personalized short links sent via private messages or emails can be particularly harmful. Attackers can redirect users to phishing sites pre-filled with personal data, aiming to extract sensitive information like passwords or payment details. Moreover, advanced shortening services might facilitate doxing and tracking, further compromising privacy.


Protecting Yourself from Short Link Threats


Total avoidance of short links is often impractical, given their widespread use. However, certain precautions can help safeguard your online experience:


1. Exercise caution with short links received via direct messages and emails.

2. Consider using tools like GetLinkInfo or UnshortenIt to preview short links before clicking.

3. Keep your devices and browsers up to date to reduce the risk of zero-click vulnerabilities.

4. Be vigilant when entering personal information on unfamiliar sites.

5. Regularly review your privacy settings on social media platforms to limit data exposure.





While short links offer convenience, they can also introduce various privacy and security risks. Being aware of these threats and adopting protective measures is crucial for maintaining a safe online presence. By staying informed and cautious, users can navigate the digital landscape with greater confidence.
