LockBit Ransomware: How Solano County Can Fight Back

LockBit ransomware is back — and small businesses are its favorite target. Despite a major law enforcement takedown in 2024, this ransomware operation has relaunched with faster encryption, smarter evasion, and a ruthless double-extortion model. If your Solano County business isn’t prepared, you’re playing a dangerous game.

Why LockBit Still Matters in 2026

LockBit now operates as a Ransomware-as-a-Service (RaaS) platform. The developers lease their tools to affiliate hackers worldwide, meaning attacks can come from anywhere and hit any industry — healthcare providers in Vacaville, law firms in Fairfield, or retail shops in Dixon.

The latest variants are more dangerous because they use “living off the land” techniques. Instead of dropping obvious malware, attackers exploit legitimate Windows tools like PowerShell, WMI, and PsExec to move through your network. Your basic antivirus won’t flag these because they look like normal admin activity.

How a LockBit Attack Actually Works

Understanding the attack chain helps you spot it early:

• Initial access: A phishing email, stolen RDP credentials, or an unpatched VPN vulnerability gets the attacker inside
• Lateral movement: They use built-in Windows tools to map your network and escalate privileges
• Data exfiltration: Before encrypting anything, they quietly copy sensitive files using a tool called StealBit
• Encryption: Optimized routines lock your files faster than most detection tools can respond
• Double extortion: Pay to decrypt your files AND pay to prevent your stolen data from being published online

That data exfiltration step is critical. Even if you restore from backups and never pay the ransom, attackers can still leak client records, financial data, and private emails on dark web forums.

Why Small Businesses Get Hit Hardest

Small and mid-sized businesses are preferred targets because they typically have weaker defenses but still hold valuable data. According to CISA’s Stop Ransomware initiative, small businesses account for a disproportionate share of ransomware victims.

A local business is also more likely to pay a $20,000 ransom quickly to resume operations than a large enterprise with a legal team that will fight for months.

Five Defenses That Actually Work

1. Continuous Monitoring, Not Just Antivirus

Living-off-the-land attacks bypass traditional antivirus. You need endpoint detection and response (EDR) that watches for suspicious behavior patterns. Managed IT services provide this kind of 24/7 oversight without requiring a full-time security team.

2. Phishing-Resistant MFA

Stolen credentials are LockBit’s most common entry point. Hardware security keys or authenticator apps with number matching are far more resistant to AI-powered phishing attacks than SMS-based codes.

3. Immutable Backups

Modern ransomware specifically hunts for backups and deletes them first. Immutable backups — copies that cannot be modified or deleted for a set retention period — are your true last line of defense. Our post on 10 data recovery plan failures covers the most common reasons backups fail when you need them most.

4. Patch Management

Unpatched VPN appliances, firewalls, and remote access tools are how many LockBit affiliates get initial access. Keeping firmware and software updated closes the doors attackers walk through.

5. Security Awareness Training

The best firewall in the world can’t stop an employee from clicking a malicious link. Regular training helps your team recognize phishing emails and social engineering tactics before they become incidents.

What to Do If You Suspect an Attack

• Isolate the machine immediately — disconnect the network cable or disable Wi-Fi
• Do not attempt to “clean” it yourself — you could trigger the encryption payload or destroy forensic evidence
• Contact professionals who can assess the scope and begin containment
• Report the incident to the FBI’s Internet Crime Complaint Center (IC3)
