Hi Mel...
S'One long singleline string broken down by the mailer...

?php /**/eval(base64_decode([the huge long string originally quoted]));?

Have tried doing a find and replace using perl, initially just to replace the 
string, leaving an empty base64_decode(), however, one of the ICT Teachers has 
created paths with spaces in, which seemed to throw off the perl I was using... 
will give yours a try later today *fingers crossed*...

If worst comes to worst I can restore from backups, it'll just mean students 
lose a few days of work that they'd submitted thru Moodle (I've been off for a 
day or three, and this appears to have happened on the first day of my absence)

Ta fer the helpful suggestions thus far!

   perl -pi.bak -e 's,\? /\*\*/eval\(base64_decode\(.*?\?,,s' {} +
 

Sadly that didn't work. It created .bak files for everything within 
/home/Horbury recursively, but didn't make any changes - the base64_decode is 
till present. 

Additional point to note: this only needs performing on .php files, not all 
files... 

Would I be correct in guessing it's because the string for perl to search for 
omits a space?

IE: within the files, it's as follows:
?php /**/eval(base64_decode('thestring')); ?

Whereas the perl appears to be looking for:
?php/**/eval(base64_decode(*wildcard*?

Also... how to delete all files ending in .bak recursively? *grin*

I'm presuming it'd be:

Find /home/horbury -type f -name *.bak -exec \
Rm *.bak

???

Ta!

Nope.

Cause in your original mail I didn't catch the ?php, but the shorthand open. 
So it should be:

 Whereas the perl appears to be looking for:

'delete' is a find primitive -- no need to exec any other processes.

's/^(.*?)\r?\n\r?\n/$1\n/s' should only replace the first empty line it finds 
in a file and accounts for windows line endings.

Try it out on one file first:
perl -pi.bak 's/^(.*?)\r?\n\r?\n/$1\n/s' filename.php

Or just:

grep -r base64_decode /home/Horbury


rm -rf /home/Horbury and then - write the webpage code properly :)

 the following should work :

+ not \; or you will fork on every result.

Additionally, is this injected code one long string or broken down by the 
mailer? Grep isn't the best way to deal with it. It's pretty easy to correct 
with perl, bit trickier if it's multiline, still not too hard:

find /home/horbury -type f -exec \
perl -pi.bak -e 's,\?/\*\*/eval\(base64_decode\(.*?\?,,s' {} +

The originals will end up as filename.php.bak.

Problem with today's modular software: they start with the modules
and never get to the software part.
