Many Internet service providers (ISPs) worldwide are alerting customers of an outage that started Saturday night and triggered DrayTek router connectivity problems.
Those affected by this incident reported seeing routers across multiple series models intermittently losing connectivity and entering boot loops.
Impacted ISPs (including
Gamma,
Zen Internet,
ICUK, and
A&A in the United Kingdom and elsewhere) confirmed these reports and linked the Internet connection issues to attacks targeting unspecified vulnerabilities, knocking the routers offline, or a buggy software update pushed by DrayTek that caused impacted devices
to enter a boot loop.
As first reported by
ISPreview, affected customers (including those in
Australia and
outside the UK) were told to upgrade their devices to the latest firmware, disable SSLVPN/Remote Access, or even switch to routers from other vendors if the issues weren't fixed.
"The cause has been narrowed down to vulnerable firmware versions on Draytek routers. If you are seeing broadband circuits exhibiting repeat short sessions, please upgrade the firmware to the latest version," ICUK added.
"We urge customers to upgrade the DrayTek router to the latest firmware, or switch out the router entirely, to restore connectivity. We have had confirmation from other end users that the latest firmware from DrayTek resolves the fault," Zen Internet said.
