AppSec Knowledge Base. However, this can be overcome by using the 'alternating' technique described below , i. Alternating between typing the login credentials and typing characters somewhere else in the focus window [48] can cause a keylogger to record more information than they need to, although this could easily be filtered out by an attacker. Similarly, a user can move their cursor using the mouse during typing, causing the logged keystrokes to be in the wrong order e. Lastly, someone can also use context menus to remove, cut, copy, and paste parts of the typed text without using the keyboard.

An attacker who is able to capture only parts of a password will have a larger key space to attack if he chose to execute a brute-force attack. Another very similar technique uses the fact that any selected text portion is replaced by the next key typed. Then, these dummies could be selected with the mouse, and the next character from the password "e" is typed, which replaces the dummies "asdfsd". These techniques assume incorrectly that keystroke logging software cannot directly monitor the clipboard, the selected text in a form, or take a screenshot every time a keystroke or mouse click occurs.
