Как работает это гигантское регулярное выражение?

Недавно я нашел код ниже в одном из моих каталогов в файле doc.php . Файловые функции или ссылки на файловый менеджер. Это очень приятно. В основном, он перечисляет все файлы в текущем каталоге и позволяет вам изменять каталоги.

Он имел доступ ко всем моим файлам (добавление, переименование, информация, удаление …). Я не помню, чтобы установить его. Я удалил его, удалил несколько подозрительных и больших файлов, простыми называемыми core и сбросил все мои пароли.

Разбивка некоторых фрагментов кода приводит к большим результатам, большинство из которых не очень информативны … Однако здесь более информативный результат.

Однако я не уверен, что понимаю, как это работает. У меня есть несколько вопросов:

Какие возможные способы могли быть получены на моем сайте / каталоге?

Как я могу отследить, как выглядят результаты preg_replace?

How to lock down your server:

There are a number of ways this could have gotten on your site. Most likely you have been hacked using Exploit Code because one of your web applications is out of date. Try updating everything, including libraries. Change passwords for everything, especially FTP, although should be using sftp or ftps.

If you control your MySQL server make sure your web application's MySQL user account is not root , and make sure you remove MySQL FILE privileges from the account. You should also go a step further and do a chmod 500 -R /path/to/web/root and do a chown www-data -R /path/to/web/root www-data is a common user for apache, but it might be differnt for your system try running <?php system("whoami")?> to figure out the user account.

Next run phpsecinfo . Modify your php.ini or .htaccess and remove all RED, and try and remove as much yellow as possible.

The e pattern modifier means the replaced code should be executed as PHP code. The series of \x?? 's as the beginning of the string are hex characters to hide the ASCII they correspond to; \x65\x76\x61\x6C is equivalent to just typing eval , but someone who sees eval in a script is going to realize immediately that something is up. The complete replacement string translates to:

 eval(gzinflate(base64_decode("...")));

I left out the ... contents, but that's the complete code the malware author is executing. You can execute just the gzinflate(base64_decode("...")) part to see the code; it's over 1000 lines long and probably not worth posting here

Q: What possible ways could this have gotten on my site / directory?

A: It probably did not got to / when it first got injected. A single 777 directory on your host would do, and so would a slew of other security holes, including compromised FTP access, trojans, blog-engines plug-ins, or cross-pollination.

The PHP initialization process of this backdoor starts by scanning the host for anti-virus utilities. Here is the specific list:

 kav nod32 bdcored uvscan sav drwebd clamd rkhunter chkrootkit iptables ipfw tripwire shieldcc portsentry snort ossec lidsadm tcplodg sxid logcheck logwatch sysmask zmbscap sawmill wormscan ninja

Since this is an obfuscation war, wouldn't it make sense to somehow obfuscate the name of these tools, or hide their very presence, as to not let malign hackers annihilate them from the get go?

Danger! A much more compact, equally evil remote access tool is described in details at http://thegothicparty.com/dev/article/server-side-virus-rat/ .

Unlike the doc.php backdoor, it is meant to be remote controlled. Same hazards and methods of eradication apply.

This all most likely happened due to the timthumb.php hack.

If you are running an outdated version of timthumb.php with your theme this is the most common exploit. I noticed that these obfuscated PHP files were appearing in timthumb's /cache/ folder so I attributed it to this hack.

Updating the timthumb file should solve this problem.
