FBI issues new ransomware warning

When was the last time you paused to consider, “What would happen to my business if all our files were suddenly inaccessible?”

This is precisely the alarming scenario the FBI is currently warning about. They've issued a new security alert regarding a dangerous ransomware group called Interlock.

If you're unfamiliar with them, don’t worry, here's what you need to know…

They emerged in September 2024, but they’re already gaining notoriety by targeting businesses and infrastructure in North America and Europe.

Interlock is motivated by money. Their strategy involves infiltrating your systems, discreetly stealing sensitive data, then encrypting everything to prevent access. They then demand a ransom, usually giving a short deadline (around four days) to pay, or they threaten to release your files on the dark web.

This “double-extortion” tactic is common among ransomware groups, but Interlock is notably aggressive.

Their methods of entry are clever. They create fake browser or security updates, booby-trapped websites, and other tricks designed to make you click without hesitation. Once inside, they deploy various malicious tools to spy, steal passwords, navigate your network, and lock files.

They're not selective about systems either. They’ve developed tools to target both Windows and Linux machines, meaning virtually any business could be at risk.

You might wonder what this means for your business. The truth is, ransomware doesn't only affect large companies you hear about in the news. Small and medium-sized businesses are prime targets because attackers know their security budgets are smaller, often viewing them as easier targets.

Imagine losing access to your client files, financial data, or essential daily systems. Even if you recover, the reputational damage can be as costly as the downtime.

So, what can you do?

The FBI’s recommendations are clear:

·         Keep your systems patched and updated to prevent attackers from exploiting old vulnerabilities.

·         Enable multi-factor authentication (the extra code you enter after your password) wherever possible. It’s one of the simplest ways to block them.

·         Use web filtering and firewalls to block malicious sites.

·         Segment your network so if one part is compromised, the entire business isn’t affected.

·         Most importantly, invest in security tools that can detect and stop suspicious activity before it spreads.

It might sound technical, but taking action now is far less painful (and cheaper) than dealing with the aftermath of an attack. The FBI doesn’t issue these warnings lightly. Interlock isn’t disappearing anytime soon, and this is the perfect opportunity to ensure your business isn’t their next target.
