KeePassXC currently does not encrypt data in memory nor explicitly clear sensitive data from deleted data structures. Our memory protections can be readily tested by using Process Hacker as shown in the following screenshots comparing KeePassXC to KeePass: (Note: it is not possible to prevent an administrator from accessing memory) We also disable “core dumps” which can expose secrets if the application crashes. If they had, the ISE attacks would have failed outright! We specifically disable reading the memory of KeePassXC. #KEEPASSXC ENCRYPTED DATABASE PASSWORD#None of the other password managers featured in the ISE report have implemented this security. #KEEPASSXC ENCRYPTED DATABASE WINDOWS#KeePassXC uses modern Windows memory security techniques available to all processes. Nonetheless, here are the techniques KeePassXC uses to protect your data: Windows Memory Protection Your best defense against this threat is to have an up-to-date virus scanner and keeping your computer physically secure. If your computer is compromised in this way, then there is very little a program can do to protect its data. Please Note: memory attacks are generally not possible unless an attacker has physical access to your machine or a malicious application is running. The following is a succinct breakdown of our security across the three platforms. This is a very complex topic with a lot of nuance. Each of these operating systems have different methods of handling memory that must be taken into account. We have worked very hard to be consistent across Windows, Linux, and MacOS platforms in terms of user experience and security. However, unlike KeePass, KeePassXC is a cross-platform application written in C++ using the Qt framework. Aside from non-sensitive header data (such as initialization information for the encryption algorithms), your entire database (usernames, passwords, notes, etc) is encrypted using industry standard methods. Similar to KeePass, we protect all data “at rest” (that is, when it is saved in the password database file *.kdbx). Although KeePassXC was not mentioned, we have thoroughly reviewed the report and address some questions it raises below. Some of you may have seen the recent vulnerability report from ISE that details various memory attacks against 1Password and KeePass, among others.
