SonicWall Gen 7 Firewalls Under Active Attack: What Business Owners Must Do Now

🚨 Core Issue

A large-scale cyberattack campaign is actively targeting businesses using SonicWall Gen 7 firewalls with SSLVPN enabled. Threat actors—linked to the Akira ransomware group—are exploiting what appears to be a zero-day or previously undisclosed vulnerability, putting businesses at serious risk of network breaches and data loss.


📅 Timeline & Context

  • Surge in attacks: Began in late July 2025, with a major spike over the past 72 hours (early August 2025).
  • Global impact: Over 20 confirmed targeted attacks, affecting small and mid-sized businesses worldwide.
  • Ransomware threat: Once inside, attackers move fast—deploying Akira ransomware within hours of gaining access.
  • Ongoing investigation: Security experts from Arctic Wolf, Google Mandiant, Huntress, and SonicWall are actively analyzing the threat.

🔍 How the Attack Works (In Simple Terms)

The attack often starts with an old user account or setting that was carried over when a company upgraded from a Gen 6 to a Gen 7 SonicWall firewall.

If that account wasn’t reset properly or protected with strong Multi-Factor Authentication (MFA), it could be exploited by hackers using stolen credentials or automated brute-force attacks.

Once inside, attackers:

  • Disable your security tools
  • Steal or encrypt your data
  • Delete your backups
  • Then demand a ransom to get your data back

✅ What You Must Do Immediately

Even if you haven’t noticed any issues, your business could be exposed. SonicWall strongly recommends that ALL companies with Gen 7 firewalls and SSLVPN enabled take these steps immediately:

🔧 1. Update Firmware

  • Upgrade to SonicOS version 7.3.0, which includes enhanced protections against brute-force attacks, account lockouts, and more control over user accounts.
  • Use SonicWall’s Firmware Update Guide or work with your IT provider to complete this step.

🔐 2. Reset All VPN-Enabled User Passwords

  • Especially important for accounts migrated from older Gen 6 firewalls.
  • This prevents hackers from logging in using old or reused credentials.

🔁 3. Enforce Strong MFA

  • Make sure Multi-Factor Authentication (MFA) is turned on for every user with remote access.

🚫 4. Enable Security Features

  • Turn on Botnet filtering and Geo-IP blocking to stop access from high-risk countries or IP addresses.
  • Sonicwall Update

📋 Your Action Plan (Checklist)

Phase What To Do
Preparation Identify if you’re using a Gen 7 firewall and whether SSLVPN is active
Immediate Update to firmware 7.3.0 and reset all VPN user passwords
Security Hardening Enable MFA, Geo-IP, and Botnet filtering
Monitor & Detect Ask your IT provider to monitor logs for unusual login attempts or access patterns
Backup Review Ensure your backups are working, offsite, and not accessible from the network
Long-Term Schedule regular firewall audits and updates, and consider advanced security monitoring

🧠 Why This Matters to SMBs

Small and mid-sized businesses are often targeted because they lack the layered security and around-the-clock monitoring of larger enterprises. But with a simple firewall misconfiguration or missed update, a single breach can halt operations, result in lost client trust, or even permanent data loss.

Ransomware attacks today are fast, targeted, and devastating. But the good news is: most breaches are preventable with the right action taken now.


✅ Final Thoughts

If your business relies on a SonicWall Gen 7 firewall—especially if you migrated from Gen 6—you need to act now. Whether you manage IT in-house or rely on a trusted provider, this issue demands immediate attention.
