Router malware worse than experts realize

Posted on Wednesday June 20, 2018

In May, security experts discovered one of the most widespread malware infections in history. Now, they're warning businesses and consumers that it's even worse than their first assessment. The VPNFilter malware poses a threat to small businesses and requires immediate attention from anyone who hasn't taken action against it.

VPNFilter recap

A team of security researchers from Cisco released a report that a strain of malware had been discovered on hundreds of thousands of routers and network devices. Originally, researchers believed it affected only Linksys, MikroTik, Netgear, and TP-Link devices.

Like many malware strains, VPNFilter infects devices that use default login credentials. But it's worse than the average cyberattack because it can destroy router hardware and cannot be removed by resetting infected devices.

As if destroying 500,000 routers wasn't bad enough, VPNFilter lets its creators spy on networks and intercept passwords, usernames, and financial information.

What's new

Just two weeks after VPNFilter was discovered, security experts announced that it targets 200,000 additional routers manufactured by ASUS, D-Link, Huawei, Ubiquiti, UPVEL, and ZTE. Worse yet, VPNFilter can alter data passing through infected routers. That means when you enter a username and password into a banking website, hackers could steal that information and show you an incorrect account balance to hide fraudulent deductions.

How to stop VPNFilter

Rebooting a router won't remove the malware, you need to factory-reset the device. Usually, all this requires is holding down the Reset button on the back of the device for 10-30 seconds. If your router has no reset button or you're unsure whether pressing it did the trick, contact a local IT provider immediately.
