Ghost Ransomware Alert
What Small Businesses Need to Know

Ransomware

The FBI and CISA have issued a cybersecurity alert about a ransomware threat called Ghost (Cring), which has been targeting businesses—including small businesses—since 2021. This ransomware exploits outdated software and security weaknesses, encrypting files and demanding payment for their release.

Cybercriminals behind Ghost ransomware are based in China and have attacked organizations across more than 70 countries. Victims include critical infrastructure, schools, healthcare providers, government entities, and many small businesses. If your business relies on outdated technology or lacks cybersecurity protections, you could be at risk.

How to Protect Your Business from Ghost Ransomware

While ransomware attacks can be devastating, there are proactive steps you can take to reduce your risk:

  1. Keep Your Systems Updated

Hackers exploit known security vulnerabilities in outdated software. Ensure that your operating systems, applications, and firmware are regularly updated with the latest security patches.

  1. Back Up Your Data

Regularly back up important files and store them offline or in a separate, secure location. If ransomware encrypts your files, having backups can help restore operations without paying a ransom.

  1. Use Strong Authentication

Enable multi-factor authentication (MFA) for all user accounts, especially email and administrative logins. This extra layer of security makes it harder for attackers to gain unauthorized access.

  1. Train Your Employees

Many ransomware attacks start with phishing emails. Educate your staff on how to recognize suspicious emails and avoid clicking on unknown links or downloading attachments from unknown senders.

  1. Segment Your Network

By limiting the ability of ransomware to spread across your entire system, network segmentation can help contain the damage in case of an attack.

  1. Monitor for Unusual Activity

Keep an eye out for unusual login attempts, unexpected software downloads, or unexplained system slowdowns. Early detection can prevent a full-scale attack.

What to Do if Your Business is Affected

If you suspect your business has been targeted by Ghost ransomware:

  • Do not pay the ransom—there is no guarantee you’ll get your files back.
  • Disconnect infected devices from your network to prevent further spread.
  • Report the attack to the FBI or CISA (Report@cisa.gov or call (888) 282-0870).
  • Contact a cybersecurity professional to assess and mitigate the damage.
