##### NOTES #####
#
# 1. Undestanding Protection Policy:
#   - Paranoid: When an  attack is detected, lock down any further keypresses until the correct password is entered. (set password in .conf file). Attack will also be logged.
#   - Normal :  When an attack is detected, keyboard input will temporarily be disallowed. (After it is deemed that the treat is over, keyboard input will be allowed again). Attack will also be logged.
#   - Sneaky: When an attacks is detected, a few keys will be dropped (enough to break any attack, make it look as if the attacker messed up.) Attack will also be logged.
#   - LogOnly: When an attack is detected, simply log the attack and in no way stop it. 

# 2. How To Use
#   - Modify the user configurable vars below. (particularly policy and password)
#   - Turn the program into a .pyw to run it as windowless script.
#   - (Opt) Use py2exe to build an .exe

Undestanding Protection Policy: #   - Paranoid: When an  attack is detected, lock down any further keypresses until the correct password is entered. (set password in .conf file). Attack will also be logged. #   - Normal :  When an attack is detected, keyboard input will temporarily be disallowed. (After it is deemed that the treat is over, keyboard input will be allowed again). Attack will also be logged. #   - Sneaky: When an attacks is detected, a few keys will be dropped (enough to break any attack, make it look as if the attacker messed up.) Attack will also be logged. #   - LogOnly: When an attack is detected, simply log the attack and in no way stop it. # 2. How To Use #   - Modify the user configurable vars below. (particularly policy and password) #   - Turn the program into a .pyw to run it as windowless script. #   - (Opt) Use py2exe to build an .exe # ################# # Speed Threshold # Size of history array # Designate Policy Type # Password used in Paranoid Mode # Allow AutoType Software (eg. KeyPass or LastPass) ################################################################################ # Password Counter (If using password) # Current Average Keystroke Speed # Previous Keypress Timestamp # History Array Timeslot # Boolean Flag to be raised in case of intrusion detection # Array for keeping track of average speeds across the last n keypresses # How often should one drop a letter (in Sneaky mode) # What was the previous window # Filename to save attacks # Program Blacklist # Logging the Attack # Paranoid Policy # MB_SYSTEMMODAL = 4096 -- Always on top. # Sneaky Policy # Drop every 5th letter # Logging Only Policy # Normal Policy # This is triggered every time a key is pressed # If an intrusion was detected and we are password protecting # Then lockdown any keystroke and until password is entered # MB_SYSTEMMODAL = 4096 -- Always on top. # Initial Condition # TypeSpeed = NewKeyTime - OldKeyTime # Blacklisting # Intrusion detected # pass execution to next hook registered # create and register a hook manager # register the hook and execute forever
