The Federal Bureau of Investigation (FBI) has issued an alert warning farm businesses to wary of ransomware attacks. The alert specifically warned agricultural cooperative businesses during critical parts of the season like planting and harvest.
The alert noted: “The FBI noted ransomware attacks during these seasons against six grain cooperatives during the fall 2021 harvest and two attacks in early 2022 that could impact the planting season by disrupting the supply of seeds and fertilizer. Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production. Although ransomware attacks against the entire farm-to-table spectrum of the food and agriculture sector occur on a regular basis, the number of cyberattacks against agricultural cooperatives during key seasons is notable.”
The FBI alert also provided direction on steps farm businesses can take to protect against ransomware and other online attacks.
- Regularly back up data, air gap, and password protect backup copies offline. Ensure copies of critical data are not accessible for modification or deletion from the system where the data resides.
- Implement a recovery plan that includes maintaining and retaining multiple copies of sensitive or proprietary data and servers in a physically separate, segmented, secure location (i.e., hard drive, storage device, the cloud).
- Identify critical functions and develop an operations plan if systems go offline.
- Implement network segmentation.
- Install updates/patch operating systems, software and firmware as soon as they are released.
- Use multi-factor authentication where possible.
- Use strong passwords and regularly change passwords to network systems and accounts, implementing the shortest acceptable timeframe for password changes. Avoid reusing passwords for multiple accounts and use strong pass phrases where possible.
- Disable unused remote access/RDP ports and monitor remote access/RDP logs.
- Require administrator credentials to install software.
- Audit user accounts with administrative or elevated privileges and configure access controls with least privilege in mind.
- Install and regularly update anti-virus and anti-malware software on all hosts.
- Only use secure networks and avoid using public Wi-Fi networks. Consider installing and using a virtual private network (VPN).
- Consider adding an email banner to messages coming from outside your organizations.
- Disable hyperlinks in received emails.
- Focus on cyber security awareness and training. Regularly provide users with training on information security principles and techniques as well as overall emerging cybersecurity risks and vulnerabilities (i.e. ransomware and phishing scams).
