VPNFilter Network Malware

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.

According to new research from Cisco Talos, activity surrounding the malware has stepped up in recent weeks and the attackers appear to be particularly interested in targets in Ukraine. 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.

The VPNFilter malware is a multi-stage, modular platform with versatile capabilities to support both intelligence-collection and destructive cyber attack operations.
