Website problem - Undefined index: HTTP_REFERER eval()'d code on line 147

Hey everyone!

Recently my website just stopped working. At around 13:00 it was all fine then 2 hours later or so i have the following error messages:

Notice: Undefined index: HTTP_REFERER in /var/www/bkkvszi/data/www/bkkvszi.hu/index.php(2) : eval()'d code(1) : eval()'d code on line 147

Warning: require(/var/www/bkkvszi/data/www/bkkvszi.hu/wp-blog-header.php): failed to open stream: No such file or directory in /var/www/bkkvszi/data/www/bkkvszi.hu/index.php(2) : eval()'d code(1) : eval()'d code on line 151

Fatal error: require(): Failed opening required '/var/www/bkkvszi/data/www/bkkvszi.hu/wp-blog-header.php' (include_path='.:/opt/alt/php73/usr/share/pear') in /var/www/bkkvszi/data/www/bkkvszi.hu/index.php(2) : eval()'d code(1) : eval()'d code on line 151

I checked every file so far and I just cannot solve it myself.
I didn't do any upgrades or anything at all it just stopped working.
Did the site get hacked by any chance?

PHP 7.3.21, Joomla 3.9.22 versions

I'd be really really glad if somebody could help!

It looks like the website was hacked. Joomla does not have any file called wp-blog-header.php. Hack code often includes eval() function calls to hide the malicious code.

Study the sticky topics in this forum how to clean the website and follow best security practice. There are also online services that audit the Joomla software.

Yes confirmed sadly it has been hacked by some [redacted] guy.
Found some comments in some files.

I'll check the forum as you've just mentioned not really sure tho how will i set everything back to its place.

Thank you for the reply tho!

Good evening,

do you have a backup if so, maybe restore it and then see if those files are clean.

Your limit has also been reached, so your hosting has taken your site offline.
