Is Your Router Vulnerable to VPNFilter Malware?

The Justice Department last week urged everyone with a small office home office (SOHO) or NAS device to reboot their gadgets immediately in order to thwart VPNFilter, a new strain of malware that can brick your router.

The FBI seized a domain used to send commands to the infected devices, but it can't hurt to reboot anyway.

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."

Those who believe they're infected should do a hard reset, which restores factory settings. Look for a small reset button on your device, though this will wipe any credentials you have stored on the device.

Below is a list of routers Symantec identified as vulnerable to VPNFilter. MikroTik tells Symantec that VPNFilter likely proliferated via a bug in MikroTik RouterOS software, which it patched in March 2017. "Upgrading RouterOS software deletes VPNFilter, any other third-party files and patches the vulnerability," Symantec says.

• Linksys E1200
• Linksys E2500
• Linksys WRVS4400N
• Mikrotik RouterOS for Cloud Core Routers: Versions 1016, 1036, and 1072
• Netgear DGN2200
• Netgear R6400
• Netgear R7000
• Netgear R8000
• Netgear WNR1000
• Netgear WNR2000
• QNAP TS251
• QNAP TS439 Pro
• Other QNAP NAS devices running QTS software
• TP-Link R600VPN

"No other vendors, including Cisco, have been observed as infected by VPNFilter, but our research continues," according to Cisco Talos, which first reported the bug.

To date, Cisco Talos estimates that at least 500,000 in at least 54 countries have been hit by VPNFilter.

The feds are pinning this attack on Fancy Bear, a hacking group also known as APT28 and Sofacy Group, among other monikers. The group is notorious for attacking governments across the world and stealing confidential files from the Democratic National Committee during the 2016 election.

New router-based solution protects home IoT devices

As we bring more and more smart devices into our homes, we potentially open ourselves up to a variety of new risks with devices opening back doors into networks or falling prey to botnets.

German antivirus company Avira is launching a new approach to home security which needs no new infrastructure on the domestic network and no configuration done by the user.

SafeThings sits within the home router and works with cloud-based machine learning. Avira licenses the product to router manufacturers and internet service providers, enabling them to protect networks from misuse and to deliver value-added IoT security services directly to end users.

"At Avira, we have been at the forefront of Artificial Intelligence innovation for a decade, being the first vendor within the security industry to identify how to apply AI to our field and to do it," says Travis Witteveen, CEO of Avira. "We have a wealth of experience in protecting both the privacy of end-users and the security of their traditional devices. Today we stand alone in the cyber security industry with the introduction of Avira SafeThings, an innovative router app and behavioral threat intelligence platform that secures all IoT devices in the home. We've designed SafeThings to effectively solve the IoT vulnerabilities without being too invasive, expensive, or complicated for the end user -- and we've done this in a way that provides additional benefits for the internet service providers and router manufacturers."

SafeThings is made up of a number of modules, Protection Cloud builds category and individual device profiles to create device management and rule definitions and automatically protect the device functionality. By analyzing metadata on gateway traffic, no invasive deep packet inspections are needed.

The Sentinel module is a software agent positioned at the gateway to each smart home, embedded in the firmware on the router, Sentinel fingerprints IoT devices and collects packet header metadata for AI analysis. After communicating with Protection Cloud, Sentinel enforces protection and communication rules.

A web-based user interface shows users in real time what each IoT device in their network is doing and enables them to see and modify firewall policies and device rules. There's also a Data Forefront API service that lets service providers and OEMs access and control SafeThings functionality, for example to drill down into specific details and control rules and actions to be taken in case of a compromised device.

It also allows for custom plugins to let SafeThings clients offer their end users additional security apps via a branded secure app store. These integrated services such as VPN or parental controls would operate at router level with management in the cloud.

"We see SafeThings as a 'B2B2C' product, providing consumers with the security and privacy protection they need while delivering it to them via the internet service providers and router manufacturers. As an embedded software solution, SafeThings is imminently flexible according to each client’s technical and marketing needs,” adds Witteveen.
