On 25 May 2018, the FBI suggested instead that users simply reboot their routers. This would temporarily remove the dangerous payload of the malware, but leave it infected with Stage 1, leading it to try re-downloading the payload, infecting the router again. The FBI said that this would help them to find the servers distributing the payload.[5][6][7]
As Symantec outlines, VPNFilter is "a multi-staged piece of malware." Stage 1 makes the connection, Stage 2 delivers the goods, and Stage 3 acts as plugins for Stage 2. "These include a packet sniffer for spying on traffic that is routed through the device, including theft of website credentials and monitoring of Modbus SCADA protocols. Another Stage 3 module allows Stage 2 to communicate using Tor."
VPNFilter "is unlike most other IoT threats because it is capable of maintaining a persistent presence on an infected device, even after a reboot," Symantec says.
Still, "rebooting will remove Stage 2 and any Stage 3 elements present on the device, [temporarily removing] the destructive component of VPNFilter. However, if infected, the continuing presence of Stage 1 means that Stages 2 and 3 can be reinstalled by the attackers." https://www.pcmag.com/news/36143 ... o-vpnfilter-malware
