Alphabet’s Jigsaw tech incubator just released Intra, a new Android app compatible with Android 4.0 or later and designed to prevent DNS manipulation attacks used in web censoring or phishing and malware attacks.
DNS is short for Domain Name System, a naming system used by Internet-connected devices to translate website URLs into IP addresses. Your device needs to issue DNS queries to a DNS server to convert between the two.
However, DNS queries can be intercepted by third parties and modified to block access to websites and online services or to redirect you to potentially malicious web pages.
Here is where Intra comes in, encrypting your Android device’s connection to the DNS server and thus preventing DNS manipulation attacks and providing you with unrestricted access to the entire Internet.
