Upgrade your SonicWall devices to avoid potential ransomware attacks, says CISA

Cyber crime officers at Leicestershire Police alerted us to a ransomware threat which targets vulnerabilities in SonicWall devices, with a local business being hit.

This comes after the Cybersecurity and Infrastructure Security Agency (CISA) warned of threat actors targeting "a known, previously patched, vulnerability" found in SonicWall Secure Mobile Access (SMA) 100 series and Secure Remote Access (SRA) products with end-of-life firmware, as reported by Bleeping Computer recently.

But what does this mean?

Well, the US federal agency added that the attackers can exploit this security vulnerability as part of a targeted ransomware attack.

SonicWall had issued an "urgent security notice" warning customers via email of the "imminent risk of a targeted ransomware attack."

The CISA urges users and administrators to review the SonicWall security notice and upgrade their devices to the latest firmware or immediately disconnect all end-of-life appliances.
