The report warns that routine financial due diligence misses such cyber risks, and urges early security-led inventory, segmentation, and credential rotation during M&A onboarding.

New SonicWall SonicOS Flaw Lets Attackers Crash Firewalls

⚠️ SonicWall has released patches for a high-severity SonicOS SSLVPN vulnerability (CVE-2025-40601) that can trigger a stack-based buffer overflow and remotely crash Gen7 and Gen8 firewalls. The company says the flaw allows a remote unauthenticated attacker to cause a DoS but reports no active exploitation or public PoC. Fixed versions are 7.3.1-7013+ for Gen7 and 8.0.3-8011+ for Gen8; admins unable to patch should disable SSLVPN or restrict access.

Hijacked VPN Credentials Drive Half of Ransomware Access

🔐 Beazley's Q3 2025 analysis shows ransomware activity rose, with three groups — Akira, Qilin and INC Ransomware — responsible for 65% of leak posts and an 11% increase in leaks versus the prior quarter. Initial access increasingly relied on valid VPN credentials (48% of incidents, up from 38%), with external service exploits accounting for 23%. The report highlights an Akira campaign abusing SonicWall SSLVPNs via credential stuffing where MFA and lockout controls were absent, and warns that stolen credentials and new infostealer variants like Rhadamanthys are fuelling the underground market. Beazley urges adoption of comprehensive MFA, conditional access and continuous vulnerability management to mitigate risk.

Akira ransomware linked to $244M in illicit proceeds

🔒 A joint US and international advisory on 14 November attributes approximately $244.17m in illicit proceeds to the Akira ransomware group since late September 2025.

Chinese Hackers Exploit Enterprise Network Appliances

🔒 A Chinese state-sponsored group tracked as RedNovember carried out a global espionage campaign from June 2024 to July 2025, compromising defense contractors, government agencies, and major corporations by exploiting internet-facing network appliances. The attackers rapidly weaponized disclosed flaws in devices from SonicWall, Ivanti, Cisco, F5, Sophos, and Fortinet, often within 72 hours of public exploit code. They deployed Go-based tools including Pantegana, Cobalt Strike, and SparkRAT, and relied on open-source tooling and legitimate services to obfuscate attribution and maintain persistent access.

Surge in SonicWall SSL VPN Attacks by Akira Actors

🔒 Security experts warn of a sharp increase in activity from Akira ransomware operators targeting SonicWall SSL VPN appliances, with intrusions traced to late July. Arctic Wolf links initial access to exploitation of CVE-2024-40766 and describes rapid credential harvesting that can enable access even to patched devices. Observed traces include hosting-provider-origin VPN logins, internal scanning, Impacket SMB activity and Active Directory discovery; organizations are advised to monitor hosting-related ASNs, block VPS/anonymizer logins and watch for SMB session patterns consistent with Impacket to detect and disrupt attacks early.

Akira Bypasses MFA on SonicWall VPNs via Reused Logins

🔐Akira ransomware operators are successfully authenticating to SonicWall SSL VPN accounts even when one-time password (OTP) multi-factor authentication is enabled. Arctic Wolf links the logins to credentials and OTP seeds harvested via an improper access control flaw tracked as CVE-2024-40766, and notes attackers can reuse those secrets after devices are patched. Once inside, actors rapidly scan internal networks, harvest backup server credentials, and use techniques such as BYOVD to sideload vulnerable drivers and disable protections. Administrators are urged to install the latest SonicOS (recommended 7.3.0) and reset all SSL VPN credentials immediately.
