What's Happening?
SonicWall has issued a warning to its customers to disable SSLVPN services on their Gen 7 firewalls due to potential exploitation by ransomware gangs. The advisory follows reports from Arctic Wolf Labs, which observed multiple Akira ransomware attacks likely using a SonicWall zero-day vulnerability since mid-July. Although the exact method of initial access remains unconfirmed, the possibility of a zero-day vulnerability is considered high. Cybersecurity firm Huntress corroborated these findings, noting that threat actors are exploiting the vulnerability to bypass multi-factor authentication and deploy ransomware. SonicWall has recommended several security measures, including disabling SSLVPN services, limiting connectivity to trusted IP addresses, and enforcing multi-factor authentication.
