Stay Safe Online: How to Protect Yourself from Pass-the-Cookie Attacks

Pass-the-Cookie Attacks

What is a Pass-the-Cookie Attack? 

A pass-the-cookie attack is a way to bypass authentication in a web application using a stolen session cookie. When a user logs in to any application on the Internet, a session cookie is created in the browser that identifies the user and allows them to keep the session active without constantly authenticating themselves. However, someone can steal and inject this session cookie into their browser. In that case, the web application will trust the session cookie and grant the thief complete access.

How Do Hackers Steal Session Cookies? 

There are several ways that hackers can steal session cookies. One standard method is through cross-site scripting (XSS) attacks, where an attacker injects malicious code into a website that steals the user’s session cookie when they visit the site. 

Another method is through phishing attacks, where an attacker sends an email or message that appears to be from a legitimate source but contains a link to a fake login page that steals the user’s session cookie when they enter their login information. Man-in-the-middle (MITM) attacks and trojan attacks are other methods that hackers use to steal session cookies.

How Can You Protect Yourself from Pass-the-Cookie Attacks? 

There are several steps you can take to protect yourself from pass-the-cookie attacks. One of the most effective ways is to use two-factor authentication (2FA) whenever possible. This adds an extra layer of security by requiring users to enter a code sent to their phone or email in addition to their password when logging in. This makes it much more difficult for hackers to access your account, even if they have stolen your session cookie.

Another way to protect yourself is by being cautious when clicking links or entering website login information. Always ensure you are on the correct website before entering your login information. Be wary of emails or messages asking you to click a link or enter your login information.

Finally, make sure that your computer and internet connection are secure. Use anti-virus software and keep it up-to-date, and avoid using public Wi-Fi networks when accessing sensitive information.

Pass-the-cookie attacks are a severe threat that can allow hackers to bypass authentication and gain access to sensitive information. Using two-factor authentication, being cautious when clicking on links or entering login information, and keeping your computer and internet connection secure can help protect yourself from these attacks and stay logged in to websites safely.

New Apple Flaw Exposes Users’ Browser History and Google Account Details

 

A bug has been detected on Apple’s Safari 15, that can leak your recent browsing activity and expose your Google User ID to other sites. The flaw was introduced to Safari 15 via the Indexed Database API (IndexedDB), which is part of Apple's WebKit web browser development engine, according to a Saturday blog post by FingerprintJS. IndexedDB can be utilized to save data on the computer, such as websites visited, so that they load faster when one returns. 

IndexedDB likewise adheres to the same-origin principle, which prohibits websites from freely interacting with one another unless they have the same domain name (among other requirements). Imagine it being under quarantine and only being able to interact with members of your family.  

Moreover, the problem discovered by FingerprintJS allows IndexedDB to break the same-origin policy, revealing data it has gathered to websites from which it did not collect it. Unfortunately, some websites, such as those in the Google network, include unique user-specific identifiers in the information sent to IndexedDB. This implies that if you're logged into your Google account, the information gathered can be utilized to accurately identify the browsing history as well as account information. It can also figure out whether you're logged into more than one account. 

FingerprintJS stated, "Not only does this imply that untrusted or malicious websites can learn a user’s identity, but it also allows the linking together of multiple separate accounts used by the same user." 

They also posted a video demonstrating the type of data that the attack can disclose. The flaw was reported by FingerprintJS at the end of November, but Apple has yet to patch it. All of this is alarming, but there's not much one can do about it at the moment. Because a private tab can't see what's happening in any other tabs, whether private or public, browsing in Safari's Private mode can limit the potential damage. However, it isn't without flaws. 

"[I]f you visit multiple different websites within the same [private] tab, all databases these websites interact with are leaked to all subsequently visited websites," wrote FingerprintJS.

Switching from Safari to another browser can protect Mac users from the flaw, but iOS and iPadOS users are out of luck. While only Safari has been affected on Mac, Apple's requirement that both iOS and iPad web browsers utilize WebKit implies the IndexedDB flaw has affected all of these systems' browsers.
