![]() ![]() How to extract all passwords from Google Chome If you know how to decrypt it, then write in the comments. What happens if I transfer the crypted.txt file to another computer and try to decrypt it with the same command? Let's try:Īnd on another computer, the decryption failed and an error was displayed:ĮRROR kuhl_m_dpapi_unprotect_raw_or_blob NTE_BAD_KEY_STATE, needed Masterkey is: How to decrypt DPAPI files on another computer If you want the decrypted data to be saved to a file, then use the /out option. You can see the source line on the screen. To decrypt, you also need to specify the /unprotect flag, otherwise information about blob (encrypted data) will only be shown without decryption: This function has one required option, it is /in, after which you need to specify the data for decryption. This file contains encrypted data, namely the line ‘Test string to encrypt’.Īs you can see, we do not need to think about master keys and passwords – the operating system does everything itself.įor decryption, the blob function is used (blob is data encrypted by this method) from the same dpapi module. Instead of displaying the encrypted data on the screen, they can be saved using the /out option:ĭpapi::protect /data:"Test string to encrypt" /out:crypted.txtĪs a result, the crypted.txt file will be created. Pay attention to the section “ Blob:” - this is the encrypted data in binary form. This command has one required option /data, after which you need to specify the path to the file you want to encrypt, or a text string.įor example, I want to encrypt the string ‘Test string to encrypt’:ĭpapi::protect /data:"Test string to encrypt" The dpapi module is used to work with DPAPI, the protect command is used to encrypt data. We will perform all subsequent actions in the mimikatz program, so run it as described in this article. Instead of going into the theoretical details of DPAPI, let's take a practical step: encrypt a string or file using DPAPI. ![]() I will not try to retell them, but simply provide links at the end of this article. Many good articles have already been written explaining how DPAPI works. ![]() DPAPI is quite simple not only for end users, but also for developers who want to use this encryption – there are two functions to encrypt and decrypt, they can be called from the application.īefore moving on to extracting passwords from web browsers and other passwords stored on Windows, let's take a closer look at DPAPI. But if you copy the file where the passwords of this browser are stored to another computer without the necessary master key, you will not be able to decrypt these passwords.Īs mentioned just above, DPAPI is used to encrypt and decrypt data. This is an important consequence: in the system for the current user it is possible to decrypt, for example, passwords from the Google Chrome web browser. A mechanism is provided in case the user password is changed: in fact, hashes from all old passwords are stored and an attempt is made to decrypt the master key until a suitable hash is found. More precisely, master keys are generated, with the help of which the data is encrypted and decrypted, and the user password is used to decrypt the master keys. The user password is used to encrypt this data. For the end user, all processes of encryption and decryption of data are transparent, that is, they do not require any action on their part. To encrypt the listed passwords and credentials, DPAPI (the Data Protection Application Programming Interface) is used. Google Talk, Skype, Dropbox, iCloud, Safari credentialsĪll these passwords are stored encrypted. Passwords for connecting to Wi-Fi networks In addition to the user password for logging into Windows (which, incidentally, may not be set), other passwords are stored in the OS: We will also continue to get acquainted with the capabilities of mimikatz. In this article, we will continue to get acquainted with Windows internals, namely how this operating system stores passwords of other applications. We also got acquainted with the mimikatz program, which we used to extract passwords in the current system, or from Windows registry files from another computer. In the article “ How to hack a Windows password” we learned where and how Windows stores user OS login passwords, learned how to extract these passwords in the form of a hash, and learned how to brute-force the password.
