But that’s not necessarily always a problem - as we’ve seen in the LastPass exploit saga, hackers can gain access to a target’s computer using vulnerable remote access apps installed on the computer. The one caveat to this security breach is it requires physical access to the machine from which the master password is to be extracted.
It’s these remnant characters that the PoC tool finds and extracts. Despite the name, it turns out this box is not so secure after all, since every character typed into the box essentially leaves a leftover copy of itself in the system memory. When you enter your master password, you do so in a custom box called SecureTextBo圎x. The exploit exists thanks to some custom code KeePass uses. As the researcher explains, this can be obtained in a variety of ways: “It doesn’t matter where the memory comes from - can be the process dump, swap file (pagefile.sys), hibernation file (hiberfil.sys) or RAM dump of the entire system.” That’s because it extracts the master password from KeePass’s memory.
