How to Protect Your Data Against a Spook.js Attack
The Internet has become an indispensable part of our lives these days. Everything we do today involves its usage. We go on the browser and then look for whatever we want.
We do not think about whether it is safe or not, because we never had to worry about it. However, the recent developments have made us realize that it is far from true. One of the most trusted web browsers, Google Chrome, was attacked which brought to everyone’s attention its vulnerabilities.
Even though it is still one of the safest browsers to use, the Sppok.js attack has made us realize that there need to be some changes done to it.
Now, the first order of business is understanding exactly what Spook.js is.
The Spook.js was developed by some developers who brought it to the attention that even after security upgrades that took place after Spectre, it was possible to retrieve sensitive data.
If you are also interested in finding the loopholes in top-notch security systems, then you can opt for a cyber security course, or information security courses. You can also go for a diploma in cyber security. In the 21st century there is going to be a lot of demand for people that possess such skills. Anyone who can find out how to stop a cyber attack even before it happens will have a lot of great career opportunities.
Now, coming back to Spook.js attacks and how to protect ourselves from them. But before that, let us take a look at how exactly it works.
So, the first thing that it attacked was a Tumblr blog. They placed Spook.js in the blog and targeted a password that was auto-filled in the login page. The password was filled in using the credential manager that is built-in in Chrome. It was observed that the blog was opened by the same Chrome process as the Login page, however, Spook.js was able to retrieve the password that was auto-filled. We show that our blog can be rendered by the same Chrome process as the login page, and that Spook.js can consequently recover the password.
In the next attempt, now Spook.js was used inside a Chrome extension. It can be seen that when a specific set of conditions are met, it is possible to access multiple extensions and execute the same process. Now, using this extension, it is possible to know which other websites were visited by the user and retrieve the sensitive information from there. They used Spook.js to read the memory of the LastPass credential manager extension. With this, they were able to recover the master password of the user’s vault.
There is a high chance that hackers will go on to use these sophisticated methods for a cyber attack. Therefore, it is the right time to do some information security courses or do a cyber security course. If you want to learn the advanced version then you can go for the diploma in cyber security.
Now, that we know what it. Let us know how we can counter Spook.js attacks.
There are three ways in which it can be done:
2. It is possible for sites to register their domain name to the Public Suffix List (PSL). It is a list of domain names under which users can register names directly, and it is maintained by Mozilla. Chrome will not be able to consolidate these pages.
3. Google has introduced a feature known as Strict Extension Isolation that is going to prevent multiple extensions from being processed at the same time, under the same memory pressure. Strict Extension Isolation, a feature that prevents multiple extensions from being consolidated into the same process under memory pressure. It will prevent Spook.js from accessing the memory of any other extension.
So, as of now after following these measures, one can avoid these attacks. However, one can expect that there is a high chance that such a cyber attack can take place. Therefore, there are going to be abundant career opportunities for people who have expertise in this field. So, now is the right time to upgrade yourself and do some information security courses or go for a cyber security course. You can do a diploma in cyber security for deeper knowledge in this field.
