VPNFilter: New Router Malware with Destructive Capabilities

Unlike most other IoT threats, malware can survive reboot.

A new threat which targets a range of routers and network-attached storage (NAS) devices is capable of knocking out infected devices by rendering them unusable. The malware, known as VPNFilter, is unlike most other IoT threats because it is capable of maintaining a persistent presence on an infected device, even after a reboot. VPNFilter has a range of capabilities including spying on traffic being routed through the device. Its creators appear to have a particular interest in SCADA industrial control systems, creating a module which specifically intercepts Modbus SCADA communications.

While VPNFilter has spread widely, data from Symantec's honeypots and sensors indicate that unlike other IoT threats such as Mirai, it does not appear to be scanning and indiscriminately attempting to infect every vulnerable device globally.

Q: What devices are known to be affected by VPNFilter?

A: To date, VPNFilter is known to be capable of infecting enterprise and small office/home office routers from Linksys, MikroTik, Netgear, and TP-Link, as well as QNAP network-attached storage (NAS) devices. These include:
