我的服务器上的恶意软件攻击

All the Index.php, header.php, footer.php files on my server have this code segment. Possible Malware. Now i would like to remove all this junk data from all my files at once. I'm using PHP on Debian system.

<?php

    Reinstalling the server is indeed the safest option.
    But without recent backups of those php scripts ...

    Anyway, sed isn't the best tool for multi-line replacements in files.
    And you'd want to remove anything between those CACHE comments.
    I would use Perl or Awk for that.

    Here's a single line perl solution that removes those comments from a file.
    (also creates a .bak copy of the original file)

    perl -i.bak -p -0 -e 's@//###=CACHE.*?CACHE END=###@@gs' index.php
    

    Note that @ was used to for the separators of the regex. Typically / is used, but this way the / don't have to be backslashed in the regex.

    For multiple *.php files (without .bak copies)

    perl -i -p -0 -e 's@//###=CACHE.*?CACHE END=###@@gs' *.php
    

    The perl flags used:

    -i[extension]     edit <> files in place (makes backup if extension supplied)
    -p                assume loop like -n but print line also, like sed
    -0[octal]         specify record separator (\0, if no argument)
    -e program        one line of program (several -e's allowed, omit programfile)
