Outline
Various messages circulating on Facebook advise users to never click on bit.ly links because they all point to viruses, rogue applications or malicious websites. Some of the warnings suggest that the inclusion of a "bit.ly" link from a friend is an indication that the friend has been "hacked".



Brief Analysis
These messages are inaccurate and misleading. Bitly is a legitimate and very popular URL shortening service. While spammers and scammers do often use bitly links, it is certainly not true that ALL bitly links are suspect. In fact, every day, the bitly service is used to shorten links that lead to very large numbers of perfectly legitimate websites. Reposting these misleading messages is counterproductive.

Detailed Analysis
A new set of inaccurate and misleading warnings is currently circulating rapidly around social network Facebook. The messages advise users that they should never click on links that contain "bit.ly" because such links always lead to viruses, rogue applications or malicious websites. Some of the warnings even suggest that the inclusion of a bitly link in a message is an indication that the sender has been "hacked". The advice is often included as part of warnings about specific malware, rogue apps, or phishing threats. While the overall warnings about these security threats may sometimes be accurate, the claims about bitly links are not.

In fact, bitly is a legitimate and very widely used link shortening service. This service, like others of its kind, allows Internet users to create a shorter version of a website link. Such shortened links make it easier for users to include long links in micro blogging platforms such as Twitter which only allow a relatively small number of characters per post. They can also be useful for email in situations where an overlong URL may wrap to the next line, thereby "breaking" the link so that it will not open the website as intended.

Bitly quite quickly became one of the most popular of the URL shortening services, especially after it began being widely used on Twitter.

Given its popularity, it is true that scammers and spammers regularly use bitly to shorten and disguise links to various malware websites, scam survey sites and rogue Facebook applications. Bitly offers extra features such as the ability to see how many people have clicked on a particular link and other metrics that may be attractive to both scammers and legitimate website operators.

However, just because bitly is sometimes used by criminals certainly does not mean that the service itself is suspect. In fact, many organizations that actively fight against scams, including Australian government anti-scam site ScamWatch regularly use bitly links. Bitly links are also used by a great many other organziations that cover a diverse range of subject areas.

Thus, spreading the spurious advice that people should never click on bitly links is counterproductive. People who take this advice may inadvertently miss out on timely information that actually helps them avoid Internet security threats.

Certainly, users should be cautious of following unknown links, but this is true of all URL shortening service links - and links in general - not just bitly links. Bitly offers browser extensions for the Firefox and Chrome browsers that allow users to review the destinations of shortened links before clicking.

If you do encounter a bitly link that points to a questionable website, you can report it to bitly.
