dnschanger-router-malware Next time when you see an advertisement of your favorite pair of shoes on any website, even if it is legitimate, just DO NOT CLICK ON IT.
…Because that advertising could infect you in such a way that not just your system, but every device connected to your network would get affected.
A few days ago, we reported about a new exploit kit, dubbed Stegano, that hides malicious code in the pixels of banner advertisements rotating on several high profile news websites.
Now, researchers have discovered that attackers are targeting online users with an exploit kit called DNSChanger that is being distributed via advertisements that hide malicious code in image data.
Remember DNSChanger? Yes, the same malware that infected millions of computers across the world in 2012.

DNSChanger works by changing DNS server entries in infected computers to point to malicious servers under the control of the attackers, rather than the DNS servers provided by any ISP or organization.
So, whenever a user of an infected system looked up a website on the Internet (say, facebook.com), the malicious DNS server tells you to go to, say, a phishing site. Attackers could also inject ads, redirect search results, or attempt to install drive-by downloads.
The most worrisome part is that hackers have combined both threats in their recent widespread malvertising campaign, where DNSChanger malware is being spread using Stegno technique, and once it hit your system, instead of infecting your PC, it takes control of your unsecured routers.
