In recent times there were many attacks on SMF sites by a user named krisbarteo. One of the things he did was to insert a code "base64_decode(xxxxxx)" in numerous files [xxxxxx refers to some undecipherable codes].
To be on the safe side, I tried to look for such a code in my php files. I found one in the Gallery.php file, Lite version 1.7.5, see below:
function ViewC()
{
die(base64_decode('UG93ZXJlZCBieSBHYWxsZXJ5IEZvciBTTUYgIG1hZGUgYnkgdmJnYW1lcjQ1IGh0dHA6Ly93d3cuc21maGFja3MuY29t'));
}
For curiosity, I downloaded version 1.8.2 and checked the Gallery.php file. The code is also found.
My question is "Is this a legitimate code?"
