I know we all have freedom of speech, but unfortunately it's not free, especially in the countries govern by the governments where they are ready to kill our voice anyhow, even by censoring the social media. The same happened few days before, when Twitter , the biggest Social Media platform, was banned by the Turkey government after an audio clip was leaked on YouTube and Twitter about the massive corruption of Turkey Prime Minister Recep Tayyip Erdoğan instructing his son to dispose of large amounts of cash in the midst of a police investigation. The Prime minister of the country, Erdoğan has full control on the old media, the television and the printing press, but he failed to stop the Ten Million Turkish citizen on twitter from sharing the audio all over the social media site, when Twitter itself reportedly refused to delete the incriminating audio of him. But it doesn't work very well, since the users have all way out. Millions of Turkey users began using Google's DNS servi...

Israeli cybersecurity researchers have disclosed details about a new flaw impacting DNS protocol that can be exploited to launch amplified, large-scale distributed denial-of-service (DDoS) attacks to takedown targeted websites. Called NXNSAttack , the flaw hinges on the DNS delegation mechanism to force DNS resolvers to generate more DNS queries to authoritative servers of attacker's choice, potentially causing a botnet-scale disruption to online services. "We show that the number of DNS messages exchanged in a typical resolution process might be much higher in practice than what is expected in theory, mainly due to a proactive resolution of name-servers' IP addresses," the researchers said in the paper. "We show how this inefficiency becomes a bottleneck and might be used to mount a devastating attack against either or both, recursive resolvers and authoritative servers." Following responsible disclosure of NXNSAttack, several of the companies i...

Cloudflare, a well-known Internet performance and security company, announced the launch of 1.1.1.1 —world's fastest and privacy-focused secure DNS service that not only speeds up your internet connection but also makes it harder for ISPs to track your web history. Domain Name System (DNS) resolver, or recursive DNS server, is an essential part of the internet that matches up human-readable web addresses with their actual location on the internet, called IP addresses. For example, when you try to open a website, say thehackernews.com, your DNS looks up for the IP address linked to this domain name and load the site. Since the default DNS services provided by ISPs are often slow and insecure, most people rely on alternative DNS providers—such as OpenDNS (208.67.222.222), Comodo DNS (8.26.56.26) and Google (8.8.8.8), to speed up their Internet. But if you use Cloudflare new 1.1.1.1 DNS service , your computer/smartphone/tablet will start resolving domain names within a bla...

Cybersecurity researchers have uncovered multiple vulnerabilities in Dnsmasq, a popular open-source software used for caching Domain Name System (DNS) responses, thereby potentially allowing an adversary to mount DNS  cache poisoning attacks  and remotely execute malicious code. The seven flaws, collectively called " DNSpooq " by Israeli research firm JSOF, echoes previously disclosed weaknesses in the DNS architecture, making Dnsmasq servers powerless against a range of attacks. "We found that Dnsmasq is vulnerable to DNS cache poisoning attack by an off-path attacker (i.e., an attacker that does not observe the communication between the DNS forwarder and the DNS server)," the researchers noted in a report published today. "Our attack allows for poisoning of multiple domain names at once, and is a result of several vulnerabilities found. The attack can be completed successfully under seconds or few minutes, and have no special requirements. We also found ...

A group of academics from the University of California and Tsinghua University has uncovered a series of critical security flaws that could lead to a revival of DNS cache poisoning attacks. Dubbed " SAD DNS attack " (short for Side-channel AttackeD DNS), the technique makes it possible for a malicious actor to carry out an off-path attack, rerouting any traffic originally destined to a specific domain to a server under their control, thereby allowing them to eavesdrop and tamper with the communications. "This represents an important milestone — the first weaponizable network side channel attack that has serious security impacts," the researchers said. "The attack allows an off-path attacker to inject a malicious DNS record into a DNS cache." Tracked as CVE-2020-25705, the findings were presented at the ACM Conference on Computer, and Communications Security (CCS '20) held this week. The flaw affects operating systems Linux 3.18-5.10, Windows Serv...

If you use the Firefox web browser, here's an important update that you need to be aware of. Starting today, Mozilla is activating the DNS-over-HTTPS security feature by default for all Firefox users in the U.S. by automatically changing their DNS server configuration in the settings. That means, from now onwards, Firefox will send all your DNS queries to the Cloudflare DNS servers instead of the default DNS servers set by your operating system, router, or network provider. As you may know, DNS-over-HTTPS (DoH) protocol performs DNS lookups — i.e., finding the server I.P. address of a certain domain name — over an encrypted connection to a DNS server rather than sending queries in the plaintext. This privacy-focused technology makes it harder for man-in-the-middle attackers, including your ISPs, to manipulate DNS queries, eavesdrop on your Internet connection, or learning what sites you visit. "This helps hide your browsing history from attackers on the network, ...

Security researchers Thursday disclosed a new critical vulnerability affecting Domain Name System (DNS) resolvers that could be exploited by adversaries to carry out reflection-based denial-of-service attacks against authoritative nameservers. The flaw, called  'TsuNAME ,' was discovered by researchers from SIDN Labs and InternetNZ, which manage the national top-level internet domains '.nl' and '.nz' for the Netherlands and New Zealand, respectively. "TsuNAME occurs when domain names are misconfigured with cyclic dependent DNS records, and when vulnerable resolvers access these misconfigurations, they begin looping and send DNS queries rapidly to authoritative servers and other resolvers," the researchers said. A recursive DNS resolver is one of the core components involved in  DNS resolution , i.e., converting a hostname such as www.google.com into a computer-friendly IP address like 142.250.71.36. To achieve this, it responds to a client's r...

A Latin America (LATAM)-based financially motivated actor codenamed FLUXROOT has been observed leveraging Google Cloud serverless projects to orchestrate credential phishing activity, highlighting the abuse of the cloud computing model for malicious purposes. "Serverless architectures are attractive to developers and enterprises for their flexibility, cost effectiveness, and ease of use," Google said in its biannual Threat Horizons Report [PDF] shared with The Hacker News. "These same features make serverless computing services for all cloud providers attractive to threat actors, who use them to deliver and communicate with their malware, host and direct users to phishing pages, and to run malware and execute malicious scripts specifically tailored to run in a serverless environment." The campaign involved the use of Google Cloud container URLs to host credential phishing pages with the aim of harvesting login information associated with Mercado Pago, an onli...

Thousands May Lose Net Access On July 9th July The warnings about the Internet problem have been splashed across Facebook and Google. Internet service providers have sent notices, and the FBI set up a special website. Thousands of Canadians could be among the hundreds of thousands of people around the world who might lose Internet access on July 9.That's the day the FBI will shut down all the "clean servers" it set up to combat a massive hacking operation. Last November the FBI arrested and charged six Estonian men behind the malware as part of Operation Ghost Click. These hackers were able to make a fortune off their project, raking in millions for ads placed on their fraudulent websites.On the eve of the arrests, the FBI hired Paul Vixie, chairman of the Internet Systems Consortium (ISC) to install two temporary Internet servers that would prevent infected users from losing access to the Internet once the DNSChanger botnet was shut down. DNS (Domain Name System) is a...

In what has become a yearly tradition, it's now time for us to present 10 of the most noteworthy incidents on the Internet from this past year. As you'll see, 2010 has been very interesting. Just like previous years, we have included problems ranging from website outages and service issues to large-scale network interruptions. If you're an avid Web user, you are bound to recognize several of them. Let's get started! The major incidents on the Internet in 2010 were… Wikipedia's Failover Fail Wikipedia has become so ubiquitous that it can't go down for a minute without people noticing. According to Google Trends for Websites , the site has roughly 50 million visitors per day. In March, servers in Wikimedia's European data center overheated and shut down. The service was supposed to fail over to a US data center. Unfortunately, the failover mechanism didn't work properly and broke the DNS lookups for all of Wikipedia . This effectively rendered the site unreachable worldwide. It took...

The Egyptian government shut down most of its country's internet not by phoning ISPs one at a time, but by simply throwing a switch in a crucial data center in Cairo. That according to a February presentation to the Department of Homeland Security's Infosec Technology Transition Council. The presentation — made by Bill Woodcock, research director of the Packet Clearing House — argues that the Egyptian Communications Ministry acted quite responsibly in the procedure it used to cut ties from the net, after the shutdown was ordered by Egypt's much-feared intelligence service. "Most of the outage was effected through a breaker flipped in the Ramses exchange, and the rest was phone calls and arm-twisting," the presentation says. 'Ramses exchange' refers to a central building in Cairo where Egyptian ISPs meet to trade traffic and connect outside of the country, a facility known as an Internet Exchange Point. The report's timeline also contradicts many observers' guesses that a smal...

Cloudflare on Tuesday said it automatically mitigated a record-setting volumetric distributed denial-of-service (DDoS) attack that peaked at 11.5 terabits per second (Tbps). "Over the past few weeks, we've autonomously blocked hundreds of hyper-volumetric DDoS attacks, with the largest reaching peaks of 5.1 Bpps and 11.5 Tbps," the web infrastructure and security company said in a post on X. "The 11.5 Tbps attack was a UDP flood that mainly came from Google Cloud." The entire attack lasted only about 35 seconds, with the company stating its "defenses have been working overtime." Volumetric DDoS attacks are designed to overwhelm a target with a tsunami of traffic, causing the server to slow down or even fail. These attacks typically result in network congestion, packet loss, and service disruptions. Such attacks are often conducted by sending the requests from botnets that are already under the control of the threat actors after having infected t...
