Analyzing this in retrospect, I probably could’ve predicted this since I couldn’t load the DLL dependency that 1Password.exe relies on, but oh well. When I attempted to reflectively load the 1Password assembly however, I was greeted with another lovely error message.

How to Reflectively Load and Retrieve Values from 1Password I started my trivial, 15-lines-of-code program, in hopes it’d be as easy I had hoped. Then I could call the same functions in the same order, using data retrieved from dnSpy debugging (such as the item ID, vault ID, etc.), and In theory, it should’ve been simple enough - copy the PInvoke signatures the legitimate 1Password binary used to call the library exports, paste them into my application, and fix up the DLL search order path in order to load the DLL itself. The first thing I tried was to simply load the 1Password DLL into my application and make the requisite function calls. Sounds easy enough, right? Attempt #1: LoadLibrary(“1Password.dll”) We know that if the database is unlocked, we can enumerate over items within the database using 1Password.get_item_data, and by passing the Overview and Details JSON byte arrays to crypt_with_vault_key, we’d have plaintext secret material. Given all this in synthesis, we now have a plan of attack.

The latter, Details, contains the username, the password, additional sections and notes, and even the password history of that secret. When the data from Overview and Details is decrypted, the former contains metadata on the secret, such as the URL it’s used at, what is it’s name or title, and any other miscellaneous information. What the Overview Byte Array Contains before Decryption. That “run” function is part of a larger suite of “Native” function calls from the 1Password DLL, some of which are immediately interesting, such as “decrypt_with_vault_key.” Tracing that function back, we see that it’s called when the user goes to inspect certain elements in the UI as well as responsible for decrypting the contents of secrets when exporting them. Throwing the executable in dnSpy and jumping to the Program’s main function, we see the main loop is short and sweet - it fixes up the DLL import path, imports 1Password.dll, and calls the exported function “run” from it. The 1Password.exe client is located in the user’s AppData folder and built in.
If you simply want to know what “worked,” I’d recommend skipping to the bottom and reading from “Attempt #4” onward. Plus, who doesn’t like reading passwords?Ī final note before proceeding - this post covers my methodology and thought process while attacking this problem. KeeThief leveraged the ClrMd debugging suite by Microsoft to walk the heap for .NET objects of interest and, since the 1Password client application is written in .NET, it felt like the perfect opportunity to get firsthand experience using it. One project that always has intrigued me is KeeThief, by Will and Lee Christensen. This was my initial motivation to dig into what’s happening under the hood.

Downloading a copy of the software and using it for awhile, I noticed that so long as 1Password remained unlocked, the passwords within it remained decrypted and readable in the UI. 1Password is a password manager developed by AgileBits Inc., providing a place for users to store various passwords, software licenses, and other sensitive information in a virtual vaults secured with a PBKDF2 master password.
