SonicWall Alerts on Surge of Attacks Against Gen 7 Firewalls Over Past 72 Hours

SonicWall has issued an urgent security advisory following a significant escalation in cyberattacks targeting Generation 7 firewalls with enabled SSLVPN functionality over the past three days.

The cybersecurity company is actively investigating whether these incidents stem from a previously disclosed vulnerability or represent a new security threat, working closely with prominent threat research organizations including Arctic Wolf, Google, Mandiant, and Huntress to assess the scope and nature of the attacks.

Attack Pattern and Scope

The recent surge encompasses both internally detected incidents within SonicWall’s monitoring systems and externally reported cases from cybersecurity research teams.

These attacks specifically target Gen 7 SonicWall firewalls where SSLVPN services remain active, suggesting a coordinated effort by threat actors to exploit remote access vulnerabilities.

The concentrated timeframe of 72 hours indicates either an organized campaign or the potential discovery and exploitation of a zero-day vulnerability affecting these enterprise-grade security appliances.

The involvement of multiple prestigious cybersecurity firms in identifying and reporting these incidents underscores the severity and widespread nature of the threat.

Arctic Wolf, Google Mandiant, and Huntress represent leading authorities in threat detection and incident response, making their collective attention to this issue particularly significant for the cybersecurity community.

SonicWall’s response demonstrates the urgency of the situation, with the company immediately engaging external threat research partners to accelerate the investigation process.

The collaborative approach includes continuous communication with both partners and customers as new information emerges.

This transparency reflects industry best practices for handling potential zero-day vulnerabilities that could affect thousands of enterprise networks worldwide.

The company has committed to releasing updated firmware and comprehensive instructions promptly should investigators confirm the existence of a new vulnerability.

This proactive stance aims to minimize potential damage while ensuring customers receive timely protection against emerging threats.

SonicWall strongly advises immediate implementation of several mitigation measures. The primary recommendation involves disabling SSLVPN services where operationally feasible, though the company acknowledges this may not be practical for all organizations.

Alternative protective measures include restricting SSLVPN connectivity exclusively to trusted source IP addresses and enabling comprehensive security services such as Botnet Protection and Geo-IP Filtering.

Additional recommendations emphasize enforcing multi-factor authentication for all remote access, though reports suggest MFA alone may provide insufficient protection against the current threat.

Organizations should also remove unused local accounts, particularly those with SSLVPN access privileges, and implement robust password hygiene practices across all user accounts.

This security incident highlights the persistent threats facing network infrastructure and the critical importance of proactive security measures.

Organizations using SonicWall Gen 7 firewalls should immediately implement recommended mitigations while awaiting further updates from the ongoing investigation.
