Revision as of 17:39, 17 February 2012

Overview

Get the status of files found in maldet scans. There are several different functions that can then be run.

Script

There are two main versions:

1) Look at only the last scan

2) Look at the entire log

Last Scan Version

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | xargs ls -lah $i 2>/dev/null

All Scans Version

[bash,n] grep "malware hit" /usr/local/maldetect/event_log | grep "{hexstring}\|{md5hash}" | awk '{print $11}' | xargs ls -lah $i 2>/dev/null

What to change

Remove everything between the do and done

Read Files

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | xargs vim 2>/dev/null

Chmod 000

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | xargs chmod 000 2>/dev/null

Remove

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | xargs rm -f 2>/dev/null

Other uses

Check Directory Permissions

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | rev | cut -d "/" -f2- | rev | uniq | xargs ls -ldh 2>/dev/null

Chmod 644 (images)

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | rev | cut -d "/" -f2- | rev | uniq | grep "image" | xargs chmod 0644

Chmod 755 (other)

[bash,n] cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | rev | cut -d "/" -f2- | rev | uniq | grep -v "image" | xargs chmod 0755

Stop Script Execution (images)

Careful with this one, they may have legitimate scripts in these directories =_= [bash,n] for i in $(cat /usr/local/maldetect/sess/session.`cat /usr/local/maldetect/sess/session.last` | grep "{HEX}\|{MD5}" | awk '{print $3}' | rev | cut -d "/" -f2- | rev | uniq | grep -v "image"); \ do if [ ! -e $i/.htaccess] then; echo -e "Options None\nAddType text/plain .html .htm .shtml .php .php3 .phtml .phtm .pl .py .cgi\n" > $i/.htaccess; else; echo "$i already has .htaccess"; fi; done

Scan Types

Scan All Users Full Home Directories

[bash,n] maldet --update-ver; maldet --update; maldet -a /home?/?/

Scan All Users Public_HTML Directories

[bash,n] maldet --update-ver; maldet --update; maldet -a /home?/?/public_html
