WordPress Gutenberg Editor fails on modsecurity2

If you use modsecurity2 Plugin Filter on a Apache2 / Apache24 Setup then on my Blogs Gutenberg fails to SAVE Pages and Drafts. Workaround: Install the old but useful “Classic Editor Plugin” and replace Gutenberg for all Users! Background: It seems the lastest stable mod_security2 Rules not modified for Gutenberg post urls!

Apache MEMCACHED UDP Protection

Current a lot of sites blogging about memcached attacks on Servers here some details: Memcached Servers need a installed and running Service called “memcached” Websites need a php-plugin like php7.0-memcached to connect via API to the memcached Service The Memcached Service uses a own Config File at debian /etc/memcached.conf By default it MUST listen to localhost or socket Admins MUST setup a FIREWALL like “ufw” (iptables) and MUST check own Server for OPEN PORTS with nmap The Problem is that Attackers can run Scripts against to your Server in a 10^6 Range like a BOTNET !! with ONE PC cause […]

Apache: Count Visits on Console

If you use a Webserver like Apache, you can use a small script to Analyse your Logs. Create a analyse-web.sh Script with: $sudo nano /home/user/analyse-web.sh insert: #!/bin/bash cat /var/log/apache2/access.log | awk '{ print $1 }' | sort | uniq -c exit 0 System Output: 1573 www.domain2.de 3568 www.domain3.de .. If you change the “$1” to other value like “$8” you will get the count of touched files or folders! This shows you attacks on single Files by abnormal high counts! You can use cron to run it every 15Minutes and send it to mailbox of a user. And this way […]

On info pages this Company says Admins should disallow crawl by robots.txt, but they IGNORE the settings! This x-guys is in my opinion against German Law “Datenschutz”. "Mozilla/5.0 (compatible; XoviBot/2.0; +http://www.xovibot.net/)" Solution: On Linux Setup a Firewall like ufw and block these IP Ranges To find out the IPs do: $sudo cat /var/log/apache2/access.log|grep xovibot.net| awk '{ print $2 }' | sort | […]
