Instead of connecting to a clean site or service, when your router is hacked, you’ll visit a rogue and hacked one. This is called a man-in-the-middle attack. When hackers exploit router vulnerabilities, gain access to it, and modify the DNS servers settings, all your Internet traffic can be forwarded to rogue servers. WHAT HAPPENS WHEN YOUR ROUTER IS ATTACKED?Īccording to an Avast Blog, this means that the router has been hacked and the DNS settings have been modified to serve hacked contents to a cyberthief. “Given the increased reliance on home networks for telehealth, distancing learning and telework, I also ask you to consider public outreach to alert your customers to steps they can take to better secure these products, including applying security updates,” Warner wrote.
Mark Warner, D-Va., the vice-chair of the Senate Intelligence Committee, sent letters to Google and other tech firms asking them to ramp up the security of their devices as a way to counter some of the security concerns raised by the work-at-home movement.
“With employees working from the comfort of their own home, attackers could use these attacks on home routers that are not properly secured to compromise work devices and gain access to sensitive data or phish employee credentials and use them to connect to the employer’s infrastructure,” Liviu Arsene, a senior cybersecurity analyst at Bitdefender, tells Information Security Media Group. These DNS hijacking attacks, which are mainly targeting users in the U.S., France, and Germany, come at a time when the COVID-19 pandemic is forcing more employees to telework, which means they’re relying on home routers to conduct business. Hijacked Routers Steering Users to Fake COVID-19 SitesĬybercriminals are waging brute-force attacks that enable them to change DNS settings on home and small business routers to redirect victims to fake/bogus COVID-19 websites that push an “infostealer” malware, according to the security firm Bitdefender.
