It’s Been a While: Let’s Talk Cybersecurity and the Latest BlackByte Attack

It’s been a couple of months since we last tackled the topic of cybersecurity, and I’m sure you’ve been busy securing your digital assets—especially with the constant news of emerging threats. Well, buckle up, because there’s a new wave of attacks making headlines, and this time, it’s the BlackByte ransomware group that’s back in the spotlight.

At Convergex, we’ve always prided ourselves on staying ahead of the curve, and with this latest cyberattack, we’re here to break down what’s happening and what you can do to protect your business.

The Latest Threat: BlackByte Ransomware Exploiting VMware ESXi Flaw

In the ever-evolving landscape of cyber threats, the BlackByte ransomware group has once again reared its head. This time, they’ve set their sights on VMware ESXi hypervisors by exploiting a vulnerability known as CVE-2024-37085. This flaw allows attackers to bypass authentication, giving them a dangerous foothold within targeted systems.

But what makes this attack particularly alarming is how swiftly the BlackByte group has incorporated this vulnerability into their arsenal. Within days of the flaw being publicly disclosed, they were already deploying it in real-world attacks. This speed highlights just how agile and resourceful modern cybercriminals have become.

How BlackByte Operates: A Closer Look

The BlackByte ransomware group isn’t new to the scene. They first emerged in 2021, right around the time the infamous Conti ransomware crew was shut down. Since then, they’ve continued to refine their tactics, making each wave of attacks more sophisticated than the last.

One of their signature moves is the use of vulnerable drivers to bypass security protections—a technique known as “bring your own vulnerable driver” (BYOVD). This allows them to disarm critical security processes, making it easier to infiltrate systems and encrypt valuable data. In the most recent attack, they dropped four different vulnerable drivers, each carefully named to avoid detection.

Additionally, they’re leveraging a well-known ransomware-as-a-service (RaaS) model, which means other cybercriminals can rent their tools and techniques to launch their own attacks. This decentralised approach makes it even more challenging to predict where and when the next strike will occur.

Why This Matters to Your Business

You might be wondering: “Why should I care about some ransomware group halfway across the globe?” The truth is, these kinds of attacks are becoming increasingly global, targeting businesses of all sizes and industries.

In fact, the professional, scientific, and technical services sectors are among the most vulnerable, with 15% of all observed attacks targeting them. Manufacturing and educational services aren’t far behind, each accounting for 13% of attacks. If your business falls within these industries, it’s crucial to stay vigilant.

But even if you’re not directly in the line of fire, ransomware attacks can still impact you through supply chain disruptions, data leaks, and financial repercussions. That’s why staying informed and proactive is key.

Lessons from the BlackByte Attack

The BlackByte ransomware group’s latest attack is a stark reminder that cybersecurity is a moving target. As attackers continue to evolve their tactics, we must evolve our defenses. Here are a few key takeaways:

  • Patch Vulnerabilities Immediately: As soon as a new vulnerability is disclosed, cybercriminals are quick to exploit it. Ensure your systems are always up to date with the latest patches.
  • Be Wary of BYOVD Tactics: The use of vulnerable drivers to bypass security measures is becoming more common. Ensure your endpoint protection is capable of detecting and mitigating these types of attacks.
  • Don’t Underestimate the Power of VPN Security: In this attack, BlackByte leveraged compromised VPN credentials to gain access. Make sure your VPNs are secure, with strong authentication measures in place.
