I am running into a lot of issues with some files being infected, however, I figured they are very similar code inside and I was thinking about grep-ing through files to find this snip of code. The code is below, you can clearly see it has a common malware form. I have checked couple more, except for the different numbers/strings, everything else is the same. I tried with globals but that obviously found millions of strings.

This is the wrong approach. ClamAV is designed for this exact purpose. Install clamav from EPEL, update it with freshclam, and scan files with clamscan or if you start the daemon, clamdscan.

That's absolutely a great idea which I tried already but it didn't seem to work = found nothing.

Did you have the opportunity to scan the files with another AV tool? If you can prove a file is indeed infected, it's good community practice to submit the file for analysis to ClamAV, here: clamav.net/reports/malware

I did not, what I did is: grep -r --include=*.html --include=*.php --include=*.htm "$GLOBALS[" /some/path/ and saved to txt file, just by running a simple search (from windows though) on that file, I found out 700+ infected files with a very similar snippet.

Mar 22 at 22:36

how is grepping for html and php files finding infections? You have a server with 700+ infected files and clamav found none of them?

This is the wrong approach. ClamAV is designed for this exact purpose. Install clamav from EPEL, update it with freshclam, and scan files with clamscan or if you start the daemon, clamdscan.

That's absolutely a great idea which I tried already but it didn't seem to work = found nothing.

Did you have the opportunity to scan the files with another AV tool? If you can prove a file is indeed infected, it's good community practice to submit the file for analysis to ClamAV, here: clamav.net/reports/malware

I did not, what I did is: grep -r --include=*.html --include=*.php --include=*.htm "$GLOBALS[" /some/path/ and saved to txt file, just by running a simple search (from windows though) on that file, I found out 700+ infected files with a very similar snippet.

how is grepping for html and php files finding infections? You have a server with 700+ infected files and clamav found none of them?

This is the wrong approach. ClamAV is designed for this exact purpose. Install clamav from EPEL, update it with freshclam, and scan files with clamscan or if you start the daemon, clamdscan.

That's absolutely a great idea which I tried already but it didn't seem to work = found nothing.

Did you have the opportunity to scan the files with another AV tool? If you can prove a file is indeed infected, it's good community practice to submit the file for analysis to ClamAV, here: clamav.net/reports/malware

– Rich
Mar 22 at 22:31

I did not, what I did is: grep -r --include=*.html --include=*.php --include=*.htm "$GLOBALS[" /some/path/ and saved to txt file, just by running a simple search (from windows though) on that file, I found out 700+ infected files with a very similar snippet.

Mar 22 at 22:36

how is grepping for html and php files finding infections? You have a server with 700+ infected files and clamav found none of them?

grep -hrils

-r : --recursive // might not need this

-i : --ignore-case // file names... maybe known unobfuscated malware function names

-l : --files-with-matches // see -n usage below

-s : --no-messages // suppress error messages

-c : count matches

-n : --line-number

Each output line is preceded by its relative line number in the file, starting at line 1. The line number counter is reset for each file processed. This option is ignored if -c, -L, -l, or -q is specified.

--include=PATTERN
--exclude=PATTERN

This might work on a file with commands, but if it were obfuscated (minified, uglified) this would not work. It would be non-trivial to permute the possibilities.

AV searches for malware by hashing files and comparing it to a database of known malware hash strings. Changing a 1 to a 0 in the file would change the file signature, so it is trivial to bypass AV. You could encode the malware in all different types of payloads and add that to your malware signature DB. https://en.wikipedia.org/wiki/Entropy_(information_theory)

The best thing you could do is look at assembly level vulns and bin diff to find issues in your code / programs. This is time consuming. For this you need a debugger.

https://reverseengineering.stackexchange.com/questions/1879/how-can-i-diff-two-x86-binaries-at-assembly-code-level

x86 assembly sound scary and confusing? Never heard of microcode?

My suggestion is to use secure software, observe and practice secure coding standards, use more secure languages, frameworks, OSes, and try not to take shortcuts.

Configuration over convention sometimes gives better security results, sometimes it doesn't.

grep -hrils

-r : --recursive // might not need this

-i : --ignore-case // file names... maybe known unobfuscated malware function names

-l : --files-with-matches // see -n usage below

-s : --no-messages // suppress error messages

-c : count matches

-n : --line-number

--include=PATTERN
--exclude=PATTERN

This might work on a file with commands, but if it were obfuscated (minified, uglified) this would not work. It would be non-trivial to permute the possibilities.

The best thing you could do is look at assembly level vulns and bin diff to find issues in your code / programs. This is time consuming. For this you need a debugger.

x86 assembly sound scary and confusing? Never heard of microcode?

My suggestion is to use secure software, observe and practice secure coding standards, use more secure languages, frameworks, OSes, and try not to take shortcuts.

Configuration over convention sometimes gives better security results, sometimes it doesn't.
