Chlonium is an application designed for cloning Chromium Cookies. From Chromium 80 and upwards, cookies are encrypted using AES-256 GCM, with a state key which is stored in the Local State file. This state key is encrypted using DPAPI. This is a change from older versions, which used DPAPI to encrypt each cookie item in the cookie database. What this means is that if you have the state key, you will always be able to decrypt the cookie database offline, without needing continual access to DPAPI keys.This essentially makes cookie databases "portable", meaning they can be moved from machine to machine, provided you have dumped the state key. The cookies themselves need to be re-encrypted when they are imported, because the state keys will differ on each user profile & machine. This can be done using the same process as decryption, by first decrypting the state key from the "target" browser, and then re-encrypting each item with the new key. The project is written in C# and has two separate components to it. The first component, chlonium.exe is the collector binary. It simply decrypts the state key and prints it. Keep a note of this key and you can decrypt cookies in the future by downloading the Cookies database file whenever you need updated cookies. By default it will attempt to decrypt the Chrome state key. If you want to dump the state key for another browser (e.g. Edge), you can specify a path to the key. For example: Chlonium.exe "c:\users\user\AppData\Local\Microsoft\Edge\User Data\Local State" [+] Statekey = 3Cms3YxFXVyJRUbulYCnxqY2dO/jubDkYBQBoYIvqfc='>> Chlonium.exe "c:\users\user\AppData\Local\Microsoft\Edge\User Data\Local State" [+] Statekey = 3Cms3YxFXVyJRUbulYCnxqY2dO/jubDkYBQBoYIvqfc= The second component, ChloniumUI.exe is the "importer" tool. This takes care of decrypting a given Cookies database file with a given state key, re-encrypting the values with the current users state key, and importing the cookies into your chosen browser. You run this on the machine you want to import the cookies into. To use it, run the ChloniumUI.exe executable. Enter the previously extracted state key, choose the Cookies file you wish to import, and select the browser you wish the import the cookies into. Now click "Import Cookies" and the cookies will be imported. ChloniumUI currently supports three Chromium based browsers: Edge, Chrome and Vivaldi. Additional browsers can be added in Browsers.cs. This adds the unintended benefit of being able to import an Edge cookie file into Chrome, or vice versa (for example), though it's probably not a good idea given that the user-agent will mismatch. Important Note: When importing the cookie file into your browser, all old cookies are cleared! A backup is copied to the current directory (https://www.kitploit.com/search/label/Directory) (with relevant time stamp). If you need to restore the previous cookies, simply copy the backup file over the Cookies file. Why Tools such as Mimikatz (https://github.com/gentilkiwi/mimikatz/wiki/module-~-dpapi) and SharpChromium (https://github.com/djhohnstein/SharpChromium) already have the capability to dump Chrome 80 cookies, why another tool? This tool is specifically aimed at making it easier to import cookies into another browser. Whilst these tools do a great job of dumping Chromium cookies (and more!), I wanted to have something that let me easily import into another browser. Third-party cookie manager (https://www.kitploit.com/search/label/Cookie%20Manager) plugins exist, but I've always found these fiddly and prone to failure. CloniumUI is designed to make this process easier by importing the cookies directly into your browser's sqlite database. Whilst this project comes with the chlonium.exe collector, which aids in dumping the state key, this is really only an example. Other tools such as Mimikatz will also dump the state key for you, in a potentially stealthier way (depending on your operating environment, execution method

etc.). Additionally, SharpDPAPI (https://github.com/GhostPack/SharpDPAPI#statekeys) will allow you to decrypt the Chromium state key file if you have DPAPI state keys, current password, or domain backup key - allowing you to dump cookies remotely over SMB! When carrying out Red Teaming, I sometimes need to dump a user's cookies multiple times over a sustained period (e.g. daily/weekly). Using a .NET assembly, Reflective DLL or other in-memory execution technique to extract individual cookies from the cookie file directly on the target system is unneccesary and exposes the operator to increased risk of detection. Instead you can simply dump the state key once, and copy the Cookies database file off whenever you need fresh cookies, without requiring additional execution. Demo See here (https://vimeo.com/452632559?quality=1080p) for a video demo. Password Import/Export ChloniumUI also supports password import and export. To use this feature, simply supply the Login Data database path instead of the Cookies db, along with the state key, and select the browser you wish to import them into (for export this doesn't matter). This allows you to either export passwords in plaintext to a file, or import them into your browser. As with cookies, you can import Chrome passwords into Edge, Edge passwords into Vivaldi etc. Offline Statekey Decryption Chlonium supports offline state key decryption (https://www.kitploit.com/search/label/Decryption) whereby you can decrypt the users statekey offline if you have all of the following files: The Local State file from: C:\Users\\AppData\Local\\User Data\Local State The DPAPI masterkey files from: C:\Users\\AppData\Roaming\Microsoft\Protect\\ and one of the following: Domain backup key .pvk file (e.g. from NTDS.dit) Domain backup key in base64 (e.g. from Mimikatz/SharpDPAPI LsaRetrievePrivateData API method) The user's password Now simply provide these values under the "Offline statekey decryption" tab, and Chlonium will attempt to decrypt the encrypted statekey by first decrypting the DPAPI masterkeys (using the backup key or password), and then using these keys to decrypt the statekey. Once the statekey is decrypted, this can be used in the "Import or Export Database" tab to retrieve cookies/passwords. Usage Note: When using the user's password to decrypt the DPAPI masterkey, Chlonium will first attempt to extract the user's SID from the BK- file from within the DPAPI masterkey folder. If this fails (or if the file does not exist), it will try to get the SID from the DPAPI masterkey folder name instead (which by default will be named after the user's SID). If you have renamed the folder, or do not have a copy of the BK file, you will not be able to decrypt the masterkey using a password. This feature makes use of the excellent SharpChrome (https://github.com/GhostPack/SharpDPAPI/tree/master/SharpChrome) and SharpDPAPI (https://github.com/GhostPack/SharpDPAPI) projects by @harmj0y. Full credit goes to the original authors of SharpDPAPI. Detection Set a SACL on the Chrome Local State and Cookies files (as well as other sensitive files such as Login Data and History). Look for suspicious (e.g. non browser related) processes opening any of these files. Take a look at this great blog post (https://medium.com/@cryps1s/detecting-windows-endpoint-compromise-with-sacls-cd748e10950) from @cryps1s about setting up SACLs for detection. For AV vendors that use a file system filter driver, consider blocking non browser-related processes from opening these files. e.g. PowerShell (https://www.kitploit.com/search/label/PowerShell) opening the Cookies file.

How to get admin password/rights while not having admin privileges

I am on a school computer managed by the school, who have admin rights. I know the admin domain name is 'admin' but I don't the password. I've tried net user admin password but access is denied. If anyone knows how to get admin rights or get the password on a non-admin account, tell me please.
