Security News > 2021 > July > SonicWall Warns of Imminent Ransomware Attacks Targeting Firmware Flaw
Network appliance vendor SonicWall has issued an urgent security notice to warn of imminent data-encrypting ransomware attacks targeting known - and already patched - firmware vulnerabilities.
The San Jose, Calif.-based SonicWall said its own threat-intelligence indicates that ransomware actors are "Actively targeting" security defects in its Secure Mobile Access 100 series and Secure Remote Access products running unpatched and end-of-life 8.x firmware.
"The exploitation targets a known vulnerability that has been patched in newer versions of firmware," the company warned, urging organizations still using its 8.x firmware to take immediate action.
The company did not provide any additional information on the imminent ransomware attacks.
Instead, the urgent notice was used to push businesses to discontinue appliances running end-of-life SMA and/or SRA firmware 8.x. "If your organization is using a legacy SRA appliance that is past end-of life status and cannot update to 9.x firmware, continued use may result in ransomware exploitation."
SonicWall said it will provide a free virtual SMA 500v through October 31, 2021 to help customers with end-of-life devices that cannot upgrade to 9.x or 10.x firmware.
