![]() NET CLR allocates these strings means that they are likely to be nicely ordered in memory. However, I've discovered that even if there are multiple passwords per session or typos, the way. Reliability of this attack can be influenced depending on how the password was typed and how many passwords were typed per session. The POC application searches the dump for these patterns and offers a likely password character for each position in the password. For example, when "Password" is typed, it will result in these leftover strings: NET works, it is nearly impossible to get rid of it once it gets created. ![]() The flaw exploited here is that for every character typed, a leftover string is created in memory. This text box is not only used for the master password entry, but in other places in KeePass as well, like password edit boxes (so the attack can also be used to recover their contents). KeePass 2.X uses a custom-developed text box for password entry, SecureTextBo圎x. No one can steal your passwords remotely over the internet with this finding alone. If you use full disk encryption with a strong password and your system is clean, you should be fine. Worst case scenario is that the master password will be recovered, despite KeePass being locked or not running at all. If you have a reasonable suspicion that someone could obtain access to your computer and conduct forensic analysis, this could be bad. ![]() However, it might be easier for the malware to be stealthy and evade the antivirus, since unlike KeeTheft or KeeFarce, no process injection or other type of code execution is necessary. If your computer is already infected by malware that's running in the background with the privileges of your user, this finding doesn't make your situation much worse.
