FBI Issues Ransomware Warning About Interlock Group

New FBI Warning: Interlock Ransomware

The FBI has issued a warning about a dangerous ransomware group called Interlock. If you run a business, this is a situation you cannot ignore.

Interlock first appeared in September 2024 and is already targeting companies and infrastructure in North America and Europe. Their goal is financial gain. They infiltrate systems, steal sensitive data, encrypt files, and demand a ransom. If the payment is not made quickly, they threaten to release the stolen data online.

This "double-extortion" method is common among ransomware gangs, but Interlock has proven particularly aggressive. They use fake browser and security updates, booby-trapped websites, and other tactics to trick users into giving them access. Once inside, their tools can steal passwords, monitor activity, and move across networks. They can target both Windows and Linux systems, meaning almost any business could be at risk.

Why Your Business Could Be a Target

Ransomware is not just a threat to large corporations. Small and medium-sized businesses are often targeted because attackers know security budgets are smaller, making them easier targets. Losing access to client data, financial records, or day-to-day systems can be devastating. Even if files are restored, downtime and reputational damage can have a lasting effect.

Steps to Protect Your Business

The FBI recommends the following actions to defend against Interlock and similar ransomware threats:

• Keep all systems updated and patched.
• Enable multi-factor authentication wherever possible.
• Use web filtering and firewalls to block malicious sites.
• Segment your network to prevent widespread infection.
• Invest in security tools that detect suspicious behavior before it spreads.

Taking these steps now can save your business time, money, and stress in the future. Acting proactively is far better than dealing with the consequences of an attack.

Cyber threats like Interlock ransomware are real, but with the right preparation, your business can stay safe and secure.
