Imminent Risk of Ransomware Attacks Exploiting Flaw in SonicWall SRA/SMA 100 Series VPN Appliances
SonicWall has issued an urgent security notice warning users of its Secure Mobile Access (SMA) 100 series and Secure Remote Access (SRA) products running end-of-life firmware about an imminent ransomware campaign using stolen credentials.
The campaign exploits a known vulnerability in 8.x firmware on the devices. SonicWall patched the vulnerability in later versions of the firmware. All users of these devices that are still running the vulnerable firmware version have been advised to update to version 9.x or 10.x of the firmware immediately.
SonicWall became aware of threat actors targeting the vulnerability in SMA 100 series and SRA products through collaboration with trusted third parties. “The affected end-of-life devices with 8.x firmware are past temporary mitigations. Continued use of this firmware or end-of-life devices is an active security risk,” explained SonicWall.
