The bitter conclusion: if you have a compromised system and use Google Chrome or another Chromium browser, you have no protection against password theft. I didn't find any passwords in the search.Ungoogled browser: Passwords show up in plain text.Google Chrome: Passwords show up in plain text.I decided to use Contains or the case-insensitive variant for the search term. The results window lists all the strings that the process hacker has found in the memory for the respective process.Īfterwards a menu with commands for the search can be opened in the result window by means of the Filter button. In the dialog box that appears, specify a string length (the default is 10). In the Properties window go to the Memory tab and select the Strings button. It is enough to right-click the main process and then click Properties in the context menu. For this I downloaded the tool Process Hacker for Windows from GitHub and used it to evaluate the memory contents. I took this as an opportunity to briefly run my own test on Saturday using Google Chrome, the Ungoogled browser (Chromium clone), and the Firefox browser. The details of his investigation can be read in the blog post Extracting Clear-Text Credentials Directly From Chromium's Memory. 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).
