Chinese cybersecurity researchers have uncovered a widespread, ongoing malware campaign that has already hijacked over 100,000 home routers and modified their DNS settings to hack users with malicious web pages—especially if they visit banking sites—and steal their login credentials. Dubbed GhostDNS , the campaign has many similarities with the infamous DNSChanger malware that works by changing DNS server settings on an infected device, allowing attackers to route the users' internet traffic through malicious servers and steal sensitive data. According to a new report from cybersecurity firm Qihoo 360's NetLab, just like the regular DNSChanger campaign, GhostDNS scans for the IP addresses for routers that use weak or no password at all, accesses the routers' settings, and then changes the router's default DNS address to the one controlled by the attackers. GhostDNS System: List of Modules and Sub-Modules The GhostDNS system mainly includes four modules:

Another day, another creepy malware for Android users! Security Researchers have uncovered a new Android malware targeting your devices, but this time instead of attacking the device directly, the malware takes control over the WiFi router to which your device is connected to and then hijacks the web traffic passing through it. Dubbed " Switcher ," the new Android malware, discovered by researchers at Kaspersky Lab, hacks the wireless routers and changes their DNS settings to redirect traffic to malicious websites. Over a week ago, Proofpoint researchers discovered similar attack targeting PCs, but instead of infecting the target's machines, the Stegano exploit kit takes control over the local WiFi routers the infected device is connected to. Switcher Malware carries out Brute-Force attack against Routers Hackers are currently distributing the Switcher trojan by disguising itself as an Android app for the Chinese search engine Baidu (com.baidu.com), and as

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, wheneve
