One of the most dangerous myths in business today? That cyberattacks only happen to other companies.
Between March and May 2025, nearly 400,000 Windows computers were infected by a credential-stealing malware called Lumma Stealer (also known as LummaC2). Microsoft confirmed that this malware campaign extracted everything from saved passwords and credit card details to cryptocurrency wallet data—an attack vector now commonly used by cybercriminal groups like Scattered Spider.
These weren’t outdated systems in a forgotten server room. Many of the infected devices belonged to active businesses and individuals who simply clicked the wrong link. Lumma was distributed through phishing emails, spoofed websites, and impersonated login pages. It worked.
The Good News: Microsoft, along with international law enforcement, successfully shut down over 2,300 malicious domains and dismantled the malware’s command structure. Cloudflare also stepped in to block many of the servers supporting Lumma’s underground marketplace.
But here’s the thing: that takedown won’t stop the next wave.
Why This Matters for Your Business
Cybercriminals don’t need to break down the front door when we’re leaving windows open. Tools like Lumma don’t rely on brute force—they rely on neglect: weak password hygiene, outdated antivirus tools, and untrained staff clicking fake login pages.
At ITGuys, we specialize in turning those weak points into walls. Our information security services are built around proactive defense. That means:
✅ Credential monitoring
✅ Endpoint detection & response (EDR)
✅ Employee phishing training
✅ Multi-factor authentication implementation
✅ Secure password and access management
✅ Routine vulnerability assessments
Lumma may be gone (for now), but its playbook is here to stay. If your team isn’t prepared, you’re at risk.
Don’t Wait for a Headline to Include You
Think of information security not as a cost—but as insurance for your reputation. Small and mid-sized companies are now prime targets because attackers know defenses are often lighter.
One bad click shouldn’t become a company-ending event.
Let’s make sure it never does.
Contact ITGuys today to review your current defenses and get a custom security strategy that fits your business.
