Keyboard cache
Keyboard cache is captured and saved in the dynamic-text.dat file. The file is loc-
ated at /private/var/mobile/Library/Keyboard/dynamic-text.dat and
contains keyboard cache, which comprises of text entered by the user. This text is cached
as part of the device's autocorrect feature and was designed to autocomplete the predictive
common words. The file keeps a list of approximately 600 words per language used on the
iOS device.
It is a binary file and can be viewed using a hex editor, as shown in the following screen-
shot. This file may contain passwords cached by the iOS device and can be used to achieve
brute force attacks on the device or an encrypted backup of the device.
