A major legal battle is unfolding after a ransomware incident involving SonicWall has prompted one of its customers to file suit over a firewall vulnerability that allegedly exposed sensitive data.<\/p>\n

What Happened?<\/strong><\/span><\/p>\n

According to reports, the Akira Ransomware gang targeted SonicWall\u2019s backup server infrastructure, stealing customer-related data during an attack that took place between July and August 2025.<\/p>\n

Initially, in mid-September 2025, SonicWall stated that approximately 5% of its customers were affected. However, following a more detailed internal review in October, the company reportedly acknowledged that all its customers using its backup servers were impacted.<\/p>\n

SonicWall later attributed the breach to a configuration error in its Firewall APIs dating back to February 2025, which created a vulnerability that was eventually exploited by the attackers.<\/p>\n

The Lawsuit<\/strong><\/span><\/p>\n

Fintech firm Marquis has filed a lawsuit in a Texas district court against SonicWall, alleging that the company failed to adequately safeguard critical customer information.<\/p>\n

According to the complaint, attackers stole personally identifiable information (PII), of over 400,000 of its customers including:<\/p>\n

\u2022\u00a0 \u00a0 Dates of birth
\u2022\u00a0 \u00a0 Full names
\u2022\u00a0 \u00a0 Postal addresses
\u2022\u00a0 \u00a0 Debit and credit card information
\u2022\u00a0 \u00a0 Social Security numbers<\/p>\n

Marquis claims the breach caused:<\/strong><\/p>\n

\u2022\u00a0 \u00a0 Financial losses
\u2022\u00a0 \u00a0 Operational disruptions
\u2022\u00a0 \u00a0 Reputational damage
\u2022\u00a0 \u00a0 Erosion of customer trust<\/p>\n

The firm argues that SonicWall\u2019s failure to secure its firewall APIs directly enabled the breach.<\/p>\n

SonicWall\u2019s Response<\/strong><\/span><\/p>\n

SonicWall has stated it is still investigating the matter and is currently seeking legal counsel before commenting directly on the lawsuit. The company maintains that the breach resulted from a configuration issue rather than a deliberate failure of its core security architecture.<\/p>\n
