Ransomware Hits Georgia Court System

The court's IT department is meeting with external agencies to determine the scope and severity of the cyberattack.

News reports have confirmed the Georgia court system has been struck with a ransomware attack, which has resulted in at least part of its digital information systems being taken offline.

An investigation is now underway; it remains unclear how many systems were compromised. Bruce Shaw, spokesman for the Administrative Office of the Courts, confirmed the attack and reports not all court systems have been affected. As a precaution, the network was taken offline and the IT department is working with external parties to determine the attack's extent.

This isn't Georgia's first foray into ransomware investigations. Back in March 2018, computer systems of the City of Atlanta were hit with a ransomware campaign that significantly disrupted government operations and caused millions of dollars in losses. In that case, Atlanta refused to pay the $50,000 ransom and is paying millions more to recover from the incident.

Georgia security recommendations
Per the article, it was stated that GA is spending millions of dollars in resolving this issue with Ransomware. So how is it that the GA court got hit again (no lessons learned from March) and they had to still fork over money to address a similar issue? Is it me or has the security staff become extremely lax or individuals from the office have forgotten aspects of their training?

Timeline:


In March, ransomware hit the court system in rural Jackson County Georgia, between Atlanta and Athens. Jackson County paid attackers $400,000. And throughout June, three Florida municipalities—Key Biscayne, Lake City, and Riviera Beach—were hit with ransomware. Lake City paid 42 bitcoin (almost $500,000) to attackers, and Riviera Beach paid 65 bitcoin (almost $600,000).


Ok, so it seems the solutions we are putting place are not working, there needs to be a radical change in how we address this issue. If the person is click on the link, shouldn't there be adequate precautions, examples as follows:
  • Segment the network where web-traffic goes to a DMZ (proxied and filtered), two diferent types of FW, utilize the firewall on the servers "iptables -I INPUT 1 -p tcp -m multiport --dport 22,80,443 -m conntrack --ctstate NEW -j ACCEPT" and drop packets from china or Russia using iptables (shell script can help with this process)
    for i in `cat china.txt`; do iptables -A INPUT -s $i -j DROP; done
    python -c "import os; file = open('chinaip.txt', 'r'); for i in file: os.system('iptables -A INPUT -s i -j DROP'); print(f'Entry succeeded: ' $?)
  • If web traffic comes through, put it on IPv6 traffic, put the network on a different type of protocol all together (internally)
  • If the data is stored on a segmented network, remove SMB/CIFS from the "Zone 0" data. The filesystem should not have a way of encrpting the data at all, the module for encrption should be removed (put this on Linux or Z/OS), even if there is a payload, the AV should catch this because the application or user is not an approved user from an SELinux standpoint.
  • Employ SELinux (MIT's file, process, filesystem, domain application used for controlling the type of execution, if it comes from the web, then the data that comes in in a folder should be setup using "setsebool -P use_encryptfs_home_dirs off" and "semanage fcontext -a -t use_encryptfs_home_dirs "/home/<username>(/.*)?" and finally run ls -lZ /home/<username> to disable encryption on the home dirs.
