Google to Experiment 'DNS over HTTPS' (DoH) Feature in Chrome 78

Google to Experiment 'DNS over HTTPS' (DoH) Feature in Chrome 78
September 11, 2019Swati Khandelwal
Immediately after Mozilla announced its plan to soon enable ' DNS over HTTPS ' (DoH) by default for Firefox users in the United States, Google today says it is planning an experiment with the privacy-focused technology in its upcoming Chrome 78. Under development since 2017, ' DNS over HTTPS ' performs DNS lookups—finding the server IP address of a certain domain name—over an encrypted HTTPS connection to a DNS server, rather than sending DNS queries in plaintext. The protocol that sends DNS queries over secure HTTPS connections has specifically been designed to prevent miscreants from interfering with domain name lookups, eventually stopping network observers, including your ISPs and attackers, from figuring out what sites you visit. Though the privacy-focused technology is also helpful in preventing attackers from redirecting unsuspecting visitors to phishing and malware sites, DNS over HTTPS could also bring its own new challenges to the enterprise security so

GhostDNS: New DNS Changer Botnet Hijacked Over 100,000 Routers

GhostDNS: New DNS Changer Botnet Hijacked Over 100,000 Routers

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:

DNSChanger Malware is Back! Hijacking Routers to Target Every Connected Device

DNSChanger Malware is Back! Hijacking Routers to Target Every Connected Device

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, wheneve

An Army of Million Hacked IoT Devices Almost Broke the Internet Today

An Army of Million Hacked IoT Devices Almost Broke the Internet Today

A massive Distributed Denial of Service (DDoS) attack against Dyn , a major domain name system (DNS) provider, broke large portions of the Internet on Friday, causing a significant outage to a ton of websites and services, including Twitter, GitHub, PayPal, Amazon, Reddit, Netflix, and Spotify. But how the attack happened? What's the cause behind the attack? Exact details of the attack remain vague, but Dyn reported a huge army of hijacked internet-connected devices could be responsible for the massive attack. Yes, the same method recently employed by hackers to carry out record-breaking DDoS attack of over 1 Tbps against France-based hosting provider OVH. According to security intelligence firm Flashpoint , Mirai bots were detected driving much, but not necessarily all, of the traffic in the DDoS attacks against DynDNS. Mirai is a piece of malware that targets Internet of Things (IoT) devices such as routers, and security cameras, DVRs, and enslaves vast numbers of

SRTT Vulnerability in BIND Software Puts DNS Protocol Security At Risk

SRTT Vulnerability in BIND Software Puts DNS Protocol Security At Risk

After the Heartbleed bug that exposed half of the Internet vulnerable to hackers thereby marking as one of the largest Internet vulnerability in recent history, the critical flaw in the implementation of the DNS protocol could also represent a serious menace to the Internet security. A Serious security vulnerability has been discovered in the algorithms of DNS software – BIND by the two Israeli students ' Roee Hay ' and ' Jonathan Kalechstein ', who are working under a project out at the Laboratory of Computer Communication & Networking in the Faculty of Computer Science at the Technion , which was led by Dr. Gabi Nakibly from Rafael (Rafael Advanced Defense Systems Ltd.). Although, Technion students have not provided any detail explanation about the vulnerability , but indicated that by exploiting the DNS protocol flaw an attacker could redirect the users who are trying to visit a legitimate website to a fake and bogus website which the attacker con

Twitter , the biggest Social Media platform used for vital communication is now banned in Turkey from the last few days, after Prime Minister Recep Tayyip Erdoğan promised to root out the social media service during an election rally this week with the help of a court order. " Twitter and so on, we will root them out. The international community can say this or that – I don't care. They will see the power of the Turkish Republic ." After the ban imposed on Twitter late on Thursday, millions of Turkey users began using Google's DNS service to bypassing censorship, that briefly helped Turks stay connected to Twitter. Turkey Government is trying to close all the possible loopholes that had allowed users to circumvent the ban and finally today the authorities have also blocked the Google DNS service (8.8.8.8 and 8.8.4.4), However the number of tweets jumped 138% in the last 24 Hours and almost 2.5 million tweets have been posted from the country after the ban imposed. Why

Recent disclosures by whistleblower Edward Snowden claiming that internet traffic is being intercepted and used by the Americans in their war on terror, force to re-think about the user's privacy and online anonymity. It has been relatively common knowledge for years that wherever we go on the web, we leave clear tracks, so it shouldn't really have come as much of a surprise to discover this has been going on. The best thing you can do to stay anonymous online is to hide your IP address . If someone knows your IP address, it is the easiest way to trace your online activity back to you and they can easily determine the geographic location of the server that hosts that address and get a rough idea of where you're located. TOR is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. Browsing with TOR is a lot like simultaneously using hundreds of different proxies that are randomized periodically.
