Security News > 2023 > May > ASUS routers knocked offline worldwide by bad security update
ASUS has apologized to its customers for a server-side security maintenance error that has caused a wide range of impacted router models to lose network connectivity.
The problem has been extensively reported on social media and discussion platforms since May 16, 2023, with people appearing puzzled by the simultaneous connectivity issues on multiple ASUS routers and others complaining about the lack of communication from the vendor's side.
"During routine security maintenance, our technical team discovered an error in the configuration of our server settings file, which could potentially cause an interruption in network connectivity on part of the routers," explains ASUS in a support bulletin.
The ASD is a built-in security daemon supplied by Trend Micro, and it is used in a wide range of router models for real-time protection against emerging threats.
ASUS says its technical team has addressed the server issue, so all impacted routers should return to normal operation now.
Hackers can breach networks using data on resold corporate routers.
