Security News > 2022 > January > Targeted ransomware takes aim at QNAP NAS drives, warns vendor: Get your updates done pronto
QNAP has urged NAS users to act "Immediately" to install its latest updates and enable security protections after warning that product-specific ransomware called Deadbolt is targeting users' boxen.
Security advice from QNAP includes disabling port-forwarding and UPnP port forwarding if your NAS is internet-facing.
A post on the QNAP user forums suggests the ransomware targets a large number of common filetypes, including CSV, various database formats such as DBF and DBX, Word DOCX, PDF files, JPG images and so on.
QNAP has long been a target of crooks looking to extort money out of people using its products.
Last year a similar alert was issued after two ransomware strains named Qlocker and eCh0raix were seen targeting QNAP boxen.
If you have a QNAP NAS, the steps to follow are outlined here.
