The FBI, CISA, and MS-ISAC have issued a joint advisory about Ghost (Cring) ransomware. These cybercriminals have been attacking outdated software and firmware since early 2021. They target vulnerable networks in over 70 countries, including China. With Windows 10’s end-of-life coming up, users are even more concerned about outdated systems.
Their victims include critical infrastructure, healthcare, schools, government agencies, tech companies, and small businesses. Ghost actors, based in China, carry out these attacks for financial gain. They frequently change their methods, making it harder to track them.
How Ghost Ransomware Works
Ghost actors switch ransomware payloads, change file extensions, and modify ransom notes to avoid detection. They also use names like Crypt3r, Phantom, and Strike. Their ransomware files include Cring.exe and Ghost.exe. Access is gained by exploiting known security flaws in unpatched systems. The FBI, CISA, and MS-ISAC recommend following their security advice to lower the risk of a Ghost ransomware attack.
Why Ransomware Is Such a Major Threat
Ransomware does more than lock data; it puts businesses in a tough spot. Extortion-based attacks force victims to choose between paying a ransom or losing critical files. Some use double extortion, where hackers steal data before encrypting it and threaten to leak it. Financial loss, downtime, and reputational damage can have lasting effects even if businesses regain access.
The risk doesn’t end after one attack. Many threats are human-operated, meaning hackers steal credentials, move through networks, and leave backdoors. Some even sell stolen logins, making future attacks easier. Ransomware-as-a-service has lowered the barrier for criminals to launch repeat attacks. A proactive, layered defense is the best way to stay ahead.
Backups Are a Key Defense Against Ransomware
Backups are one of the best ways to recover from a ransomware attack, but they must be protected. If hackers can access them, they may encrypt or delete the files, making recovery impossible. To prevent this, store backups offline or in a separate, secure network that attackers can’t easily reach.
It’s also vital to test backups regularly to make sure they work when needed. Keeping multiple copies, both on-site and in the cloud, adds extra protection. With secure, up-to-date backups, businesses can restore their systems quickly without paying a ransom.
Ghost Ransomware Isn’t the Only Threat
Beyond the recent FBI ransomware warning, this type of threat has been a growing problem for years. Some attacks spread fast, while others target specific industries or use new tricks to avoid detection. Here are some of the most well-known ransomware threats and what makes them stand out.
- CryptoLocker (2013-2014): One of the first major ransomware attacks. It spread through email attachments and locked files until law enforcement shut it down.
- Reveton (2012-2014): Also called “police ransomware.” It froze victims’ screens and claimed they had committed a crime, demanding a fake fine.
- WannaCry (2017): Spread worldwide in just days. It used a Windows flaw to infect hundreds of thousands of computers.
- Petya & NotPetya (2016-2017): These attacks encrypted entire hard drives instead of just locking files. NotPetya later turned out to be a cyberweapon.
- Ryuk (2018-Present): Targets big businesses, hospitals, and government agencies. It’s known for demanding huge ransom payments.
- Conti (2019-2022): A ransomware group that offered attacks as a service. They also leaked stolen data to pressure victims into paying.
- LockBit (2019-Present): One of today’s most active ransomware types. It spreads automatically and steals data before encrypting files.
- DarkSide (2020-2021): Infamous for shutting down the Colonial Pipeline, causing major fuel shortages in the U.S.
- BlackCat (2021-Present): A modern ransomware strain written in Rust. It’s known for targeting large companies and using double-extortion tactics.
Ransomware keeps evolving, with attackers finding new ways to break in. Staying safe means using strong cybersecurity, keeping systems updated, and training employees to spot threats. The best defense is always staying prepared.
More Ways To Protect Your Business Against Ransomware
Ghost ransomware spreads by exploiting weak security. Organizations can lower their risk by strengthening defenses, monitoring for threats, and training employees to spot attacks.
Apply Security Updates
Hackers target outdated software and firmware to break into systems. Regularly installing updates and security patches helps close these gaps and blocks attackers from exploiting known weaknesses.
Limit Ransomware Spread
Once inside a network, ransomware spreads fast. Segmenting networks prevents attackers from moving freely. Disable unused ports and protect remote access with firewalls or VPNs to limit entry points.
Require Multi-Factor Authentication (MFA)
Weak or stolen passwords make it easy for hackers to break in. Phishing-resistant MFA adds an extra layer of protection, keeping accounts secure even if login details are stolen.
Monitor for Suspicious Activity
Ransomware operations create unusual network activity, like scanning for devices or running hidden scripts. Monitoring and investigating early signs can help stop an attack before it spreads. Limiting PowerShell access also reduces risk since attackers often misuse it.
Strengthen Email Security
Many attacks start with phishing emails. Train employees to spot suspicious messages and avoid clicking unknown links. Advanced email security filters and protections like DMARC, DKIM, and SPF help block fake emails.
Invest in Cybersecurity Training
Technology alone isn’t enough. Employees need regular training on phishing, passwords, and security best practices to recognize and report threats before they cause damage.
Taking these steps makes ransomware attacks harder to launch and easier to stop. Strong security, monitoring, and employee awareness are key to staying protected.
