Network attached storage maker QNAP's customers have reported being hit by a mystery issue that disables software updates by hijacking entries in host machines' hosts file. The full effects are, as yet, unknown – but users have reported that the most visible symptom is that some 700 entries are added to the /etc/hosts file that redirect a bunch of requests to IP address 0.0.0.0. This, said forlorn QNAP forum user ianch99, stopped his antivirus from updating by sinkholing all of the software's requests to the vendor's website. So far the only cure appeared to be a script provided by QNAP itself, which one helpful Reddit user posted the link to after apparently being given it by one of the storage firm's techie in live chat.
