Gootloader infection cleaned up

February 27th, 2022

Dear blog owner and visitors,

This blog had been infected to serve up Gootloader malware to Google search victims, via a common tactic known as SEO (Search Engine Optimization) poisioning dialux kostenlos herunterladen. Your blog was serving up 158 malicious pages. Your blogged served up malware to 0 visitors.

I tried my best to clean up the infection, but I would do the following:

Upgrade WordPress to the latest version (one way the attackers might have gained access to your server)
Upgrade all WordPress themes to the latest versions (another way the attackers might have gained access to your server)
Upgrade all WordPress plugins (another way the attackers might have gained access to your server), and remove any unnecessary plugins lego technic app herunterladen.
Verify all users are valid (in case the attackers left a backup account, to get back in)
Change all passwords (for WordPress accounts, FTP, SSH, database, etc.) and keys microsoft office word 2010 kostenlos downloaden deutsch. This is probably how the attackers got in, as they are known to brute force weak passwords
Run antivirus scans on your server
Block these IPs (5.8.18.7 and 89.238.176.151), either in your firewall, .htaccess file, or in your /etc/hosts file, as these are the attackers command and control servers, which send malicious commands for your blog to execute
Check cronjobs (both server and WordPress), aka scheduled tasks haushaltsbuch zum downloaden kostenlos. This is a common method that an attacker will use to get back in. If you are not sure, what this is, Google it
Consider wiping the server completly, as you do not know how deep the infection is fussball.de herunterladen. If you decide not to, I recommend installing some security plugins for WordPress, to try and scan for any remaining malicious files. Integrity Checker, WordPress Core Integrity Checker, Sucuri Security,
and Wordfence Security, all do some level of detection, but not 100% guaranteed
Go through the process for Google to recrawl your site, to remove the malcious links (to see what malicious pages there were, Go to Google and search site:your_site.com agreement)
Check subdomains, to see if they were infected as well
Check file permissions

Gootloader (previously Gootkit) malware has been around since 2014, and is used to initally infect a system, and then sell that access off to other attackers, who then usually deploy additional malware, to include ransomware and banking trojans herunterladen. By cleaning up your blog, it will make a dent in how they infect victims. PLEASE try to keep it up-to-date and secure, so this does not happen again mehrer fotos von icloud herunterladen.
