Find base64 code in php files??

Question

PHP

Is there any program or utility, maybe a script of any kind,
that looks for base64 encoded files ???
It would be possible to search immediately by base64_decode, but this function and the base64 code itself are scattered throughout the code.
What are the options ?

Answer 1

The regular expression that matches base64.
As far as I know, searching through files can be done with Notepad++, or grep on Linux.
You may need to first copy the project and remove all whitespace.
Try Revisium if it's a virus. It seems to be looking for not only the base64_encode and _decode functions, but also base64 itself.
