He found similar vulnerabilities in Microsoft's Edge browser and suspects it is no different for other Chromium clones. The security researcher successfully tested examples of session hijacking for Gmail, OneDrive and GitHub. This is true even if they are protected by an MFA mechanism – because then "session cookies" could be read and used.

The extracted data can be used to hijack user accounts. This information can be effectively extracted from a standard process (without elevated state) running on the local computer that has direct access to Chrome's memory (using the OpenProcess and ReadProcessMemory APIs).

Cookie data (value and properties of cookies) is stored in Chrome's memory in plain text (if the application in question is active).

In addition to the data entered dynamically when logging into certain web applications, an attacker can trick the browser into loading all passwords stored in the password manager into memory ("login data" file).

This included the issue of "passwords being stored in the memory of running processes." A nightmare for usersĪfter these findings, the security researcher started to take a closer look at what the Google Chrome browser was up to and could hardly believe his eyes what he found out: He then started looking a little deeper and found that Satyam Singh had already addressed security issues in browsers in his 2015 blog post Browser-based vulnerabilities in web applications.

To his surprise, he found that the password was stored in plain text in several different places in the memory of two of those processes. Spontaneously, he decided to check if a password he had recently entered into the browser appeared in one of these dumps.

He had created a mini-dump of all active Chrome.exe processes as part of a project. It's a discovery by chance, what Zeev Ben Porat made. I came across the following tweet on Twitter this week from CyberArk Labs security researchers, who disclose the issue and describe it in more detail in the blog post Extracting Clear-Text Credentials Directly From Chromium's Memory.
