There’s a new ransomware playbook.
It doesn’t try to evade your security tools.
It just kills them.

Attackers are using BYOVD (Bring Your Own Vulnerable Driver):

• They load a legitimate, signed Windows driver
• Exploit it to get kernel-level access
• Then shut down your EDR/antivirus like any normal process

No alerts. No resistance. Just silence.

From there, encryption is trivial.

This is already being packaged into single payloads:
break in → disable security → encrypt
All in one move.

Execution time: minutes, not days.

The uncomfortable truth:

“We have EDR” is no longer a security strategy.

Attackers don’t need to bypass your defenses anymore.
They just turn them off.

What actually matters now for SMBs

If you’re running a small or mid-sized business, don’t overcomplicate this. Focus on what still works:

1. Assume endpoint security will fail
Get logs off the machine.
If the endpoint goes dark, you still need visibility.

2. Lock down drivers
Enable Microsoft’s vulnerable driver blocklist and HVCI.
This directly breaks the BYOVD path.

3. Remove admin-by-default
Most of these attacks require elevated privileges.
Reduce them aggressively.

4. Secure your entry points
MFA everywhere.
No exposed RDP.
Monitor logins.

5. Fix your backups (seriously)
Immutable.
Isolated.
Tested.
If you can’t restore fast, nothing else matters.

6. Watch behavior, not just malware
Multiple security tools stopping at once = incident.
Treat it that way.

The shift

Cybersecurity is no longer about detection.
It’s about resilience when detection fails.
Attackers are faster, cheaper, and more automated than ever.
SMBs are the easiest targets.

So the real question is no longer:
“Can we stop every attack?”

It’s:
“Can we survive one?”

Why we’re building EspressoLabs

At EspressoLabs, we’re building for exactly this reality.
We assume:

• Endpoints will get compromised
• Security tools can be disabled
• Attacks will move fast

So instead of relying on a single control point (like EDR), we focus on:

• Out-of-band visibility (you still see the attack when endpoints go dark)
• Behavior-based detection (not signature games)
• Fast containment + recovery workflows

The goal is simple:

Even if attackers get in and kill your defenses — they still lose.
