15. datAshur SSD Brute Force Protection

What is Brute Force Attack?
A Brute Force Attack is a means of breaching a cryptographic data defense scheme by systematically running an astronomi-
cal number of decryption possibilities. With AES 256 having never been cracked, the data stored on a datAshur SSD is well
protected against Brute Force. Brute Force attacks aren't necessarily aimed at the bulk of the data itself, but rather, at the
drive's access PINs. PINs are usually the weakest links of any data protection plan, and as such, PINs are essentially all that a
brute-force attack needs to decrypt.
Brute Force Feature:
1. After three unsuccessful attempts, the datAshur SSD will add additional time delays to each subsequent try thereafter.
The RED LED will blink the number of failed attempts after three, all the way to the tenth (and final) try.
2. After up to ten unsuccessful attempts, the keypad will lock and no functions will work and the LED will blink
rate of three flashes per second.
3. From this point, the datAshur SSD will only allow up to ten additional attempts before the datAsshur SSD assumes that it
is under brute-force attack and automatically deletes all of its data.
4. To gain these ten extra attempts, press and hold the 5 button and then press the
GREEN LED's blink alternately.
5. Enter the code "LastTry" (5278879) and press the
You will now have ten additional attempts. If after this point 10 more attempts have failed, the
datAshur SSD will need to be reset
6. When the datAshur SSD is successfully unlocked, the Brute Force counter will return to zero.
Note: The number of attempts possible, both before and after the LastTry (5278879) code is entered, can
be set (in Admin mode) between two and ten attempts. Setting the before/after attempts to the minimum of
two would allow for a total of four attempts (two before entering the last try code and two after.)
To reduce the number of Brute Force attempts:
1. Enter the Admin mode. (Hold
Admin PIN and press the
2. Press and hold the UNLOCK
3. Press the number of before/after attempts desired on the numeric keypad ( 2 - 9 .) The
number of times to correspond to the number you have entered (for example: the 8 button will result in eight blinks,
and yield eight attempts before the LastTry code and another eight attempts after, yielding a total of 16.) To return the
datAshur SSD to its default setting, press the 1 then the 0 button to change the number back to ten attempts.
Note: The number of before and after attempts are the same, i.e. 4 before / 4 after, 8 before / 8 after, etc.
