SonicWall Credential Stuffing Attack Compromises 30 Organizations in July 2026
In late July 2026, Huntress researchers identified a credential stuffing campaign targeting SonicWall VPN and firewall accounts, compromising 30 organizations within 41 hours. Attackers utilized legitimate credentials to access 92 unique user accounts across various SonicWall devices, indicating a broad and opportunistic approach. The intrusions ceased abruptly, suggesting potential pre-positioning for future attacks. This incident underscores the persistent threat of credential-based attacks on network infrastructure. Organizations must prioritize robust authentication mechanisms and continuous monitoring to mitigate such risks.
