Cloudbleed – Behind the scenes

Cloudbleed is a bug which is alleged to have originated from the renowned company Cloudflare. As you may already know, Cloudflare offers internet security and infrastructure to some of the world’s biggest tech companies. These include Cisco, Zendesk, Nasdaq etc. As such, if you have used a website that uses CloudFlare’s services, chances are that your information may also have been leaked unceremoniously by this bug.

How does it work?

Cloudbleed may not be as dangerous as Heartbleed. However, it is being speculated that the damage caused by Cloudbleed is still not completely known. As such, the actual damage may be a lot more. Up till now, only 3400 websites are reported to have been affected by the bug. However, these websites were Cloudflare’s clients. There might be a number of other websites that might also have been affected.

Essentially, secured websites whose addresses have “https”, instead of just “HTTP”, in the beginning, prevent private information such as one’s address or passwords to be leaked and Cloudflare provides the necessary infrastructure for the secure movement of information between such websites. However, due to Cloudbleed, the information got saved and was also cached by search engines such as Google. Hence, the information could be easily retrieved by any hacker.

As of now, all that is known is that, Uber, OKCupid, and FitBit are among the websites that were affected. However, the good news is that Cloudflare has now fixed the bug and it is no longer on the loose.

How to defend oneself from the bug?

To date, there is no clear-cut answer to this. What has been leaked cannot be made secure again. Nevertheless, one should change one’s passwords immediately. Furthermore, websites that use Cloudflare are to be avoided. Cloudflare has a list of the clients that it serves on its website.

For Cloudflare’s clients, it might be a good idea to release a forced alert to your visitors instructing them to change their passwords.

If you have an account on it is advised to change your password. Also, lets users sign in with their Facebook account so if you have ever signed in using your Facebook account change your Facebook account password as well.
