Replaces each keyword character with mixed case value (e.g. SELECT -> SeLeCt)
|
|
|
|
Tested against:
|
|
* SQLite 3
|
|
|
|
Notes:
|
|
* Useful to bypass very weak and bespoke web application firewalls
|
|
that has poorly written permissive regular expressions
|
|
* This tamper script should work against all (?) databases
|
|
* Usefull when some keywords like 'as' are part or words like 'last'
|
|
and that randomcase temper script get you caught because it outputted
|
|
'lasT' ('as' is flagged where 'aS' or 'As' is not).
