UPDATE — How an army of million of hacked Internet-connected smart devices almost broke the Internet today. Cyber attacks are getting evil and worst nightmare for companies day-by-day, and the Distributed Denial of Service (DDoS) attack is one such attacks that cause a massive damage to any service. Recently, the Internet witnessed a record-breaking largest DDoS attack of over 1 Tbps against France-based hosting provider OVH, and now the latest victim of the attack is none other than Dyn DNS provider. A sudden outage of popular sites and services, including Twitter, SoundCloud, Spotify, and Shopify, for many users, is causing uproar online. It's because of a DDoS attack against the popular Domain Name System (DNS) service provider Dyn, according to a post on Ycombinator . DNS act as the authoritative reference for mapping domain names to IP addresses. In other words, DNS is simply an Internet's phone book that resolves human-readable web addresses, like thehackerne

In past months, we have reported about critical vulnerabilities in many wireless Routers including Netgear, Linksys,  TP-LINK, Cisco, ASUS, TENDA and more vendors, installed by millions of home users worldwide. Polish Computer Emergency Response Team (CERT Polska) recently noticed a large scale cyber attack ongoing campaign aimed at Polish e-banking users. Cyber criminals are using known router vulnerability which allow attackers to change the router's DNS configuration remotely so they can lure users to fake bank websites or can perform Man-in-the-Middle attack. ' After DNS servers settings are changed on a router, all queries from inside the network are forwarded to rogue servers. Obviously the platform of a client device is not an issue, as there is no need for the attackers to install any malicious software at all. ' CERT Polska researchers said. That DNS Hijacking trick is not new, neither most of the router vulnerabilities are, but still millions of r

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

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

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

After having attended the past couple of DEFCONs, I'm really excited to be speaking at DEFCON 18 this year. In anticipation of my presentation, "How to Hack Millions of Routers", I thought I'd take this opportunity to answer some questions, offer some background information, and give a quick teaser about the talk. Most people assume that because they don't have remote administration enabled on their router, external attackers cannot access their router's administrative Web interface. However, for many routers this is simply not true; anyone with a registered domain can in fact gain full interactive access to the router's internal Web interface in order to exploit vulnerabilities or log in to the device (either via the router's default password or a brute-force attack), at which point they can view settings, change settings and generally do whatever else they want with the router*. However, this attack is not restricted to the primary Web

It is no secret that cybercriminals are becoming dramatically more adept, innovative, and stealthy with each passing day. While new forms of cybercrime are on the rise, traditional activities seem to be shifting towards more clandestine techniques that involve the exploitation of standard system tools and protocols, which are not always monitored. The latest example of such attack is DNSMessenger – a new Remote Access Trojan (RAT) that uses DNS queries to conduct malicious PowerShell commands on compromised computers – a technique that makes the RAT difficult to detect onto targeted systems. The Trojan came to the attention of Cisco's Talos threat research group by a security researcher named Simpo, who highlighted a tweet that encoded text in a PowerShell script that said 'SourceFireSux.' SourceFire is one of Cisco's corporate security products. DNSMessenger Attack Is Completely Fileless Further analysis of the malware ultimately led Talos researchers to

Threat actors associated with the Roaming Mantis attack campaign have been observed delivering an updated variant of their patent mobile malware known as Wroba to infiltrate Wi-Fi routers and undertake Domain Name System ( DNS ) hijacking. Kaspersky, which carried out an  analysis  of the malicious artifact, said the feature is designed to target specific Wi-Fi routers located in South Korea. Roaming Mantis, also known as Shaoye, is a long-running financially motivated operation that singles out Android smartphone users with malware capable of stealing bank account credentials as well as harvesting other kinds of sensitive information. Although primarily  targeting the Asian region  since 2018, the hacking crew was detected  expanding  its  victim range  to include France and Germany for the first time in early 2022 by camouflaging the malware as the Google Chrome web browser application. The attacks leverage smishing messages as the initial intrusion vector of choice to deliver

Cybersecurity researchers have disclosed a new class of vulnerabilities impacting major DNS-as-a-Service (DNSaaS) providers that could allow attackers to exfiltrate sensitive information from corporate networks. "We found a simple loophole that allowed us to intercept a portion of worldwide dynamic DNS traffic going through managed DNS providers like Amazon and Google," researchers Shir Tamari and Ami Luttwak from infrastructure security firm Wiz  said . Calling it a "bottomless well of valuable intel," the treasure trove of information contains internal and external IP addresses, computer names, employee names and locations, and details about organizations' web domains. The findings were  presented  at the Black Hat USA 2021 security conference last week. "The traffic that leaked to us from internal network traffic provides malicious actors all the intel they would ever need to launch a successful attack," the researchers added. "More than t

Web hosting company has announced that Amazon would have access to the Domain Name System (DNS) services, the game will give the DNS hosting as well. Thus, Route 53 will become part of the web hosting, pay-as-you-go DNS hosting service, which pays the amount of DNS issues can be resolved. DNS is the term used when the domain name has been translated into a numeric IP address. Compared with other traditional DNS server that contains the zone file, Route 53 has some differences. It supports the traditional types of records, including records IPv4 and IPv6, and can be displayed in the web services hosted in the cloud providers and traditional single server. The service is likely to encourage users who want a backup DNS server to a remote network, taking into account that large sites usually prefer to monitor the Internet a vital service. However, after the controversial case, Wikileaks, the ability Amazon DNS hosting provider can be called into question for many, especially sites that

When you are trying to get another layer of cyber protection that would not require a lot of resources, you are most likely choosing between a VPN service & a DNS Security solution. Let's discuss both.  VPN Explained VPN stands for Virtual Private Networks and basically hides your IP and provides an encrypted server by redirecting your traffic via a server run by a VPN host. It establishes a protected connection in public networks. It does protect your actions from being seen by your ISP and potential hackers, however, it does not provide full protection and can still let intrusions happen.  Worth noting, VPN does gain access to restricted resources in your region, but bear in mind, it might be collecting your personal data. This problem relates mostly to free and cheap VPN services. In addition to that, VPNs, depending on their type, can proxy requests or not. Most of the free ones do not even encrypt your data. According to Cybernews, last year 20 million emails and othe

DDoS attackers attempted to bring down an Banking services earlier this week using one of the largest Distributed denial of service attack using DNS reflection technique. Prolexic, the global leader in Distributed Denial of Service (DDoS) protection services, announced  that it has successfully mitigated the largest DNS reflection attack ever recorded, which peaked at 167 Gigabits per second (Gbps). The company did not name the target of the digital assault. DNS-reflection was the attack method used in Operation Stophaus , an attack waged in March by The Spamhaus Project, a Geneva-based not-for-profit organization dedicated to fighting Internet spam . When Spamhaus was assaulted by a vast 300Gbps peak DNS reflection attack, it engaged the help of a content delivery network (CDN) called CloudFlare to help defend itself. The DNS Reflection Denial of Service (DrDoS) technique exploits security weaknesses in the Domain Name System (DNS) Internet protocol. Using Internet protocol spoof

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

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:

Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users' sensitive information, login credentials and the secret code for two-factor authentication. In order to trick victims into installing the Android malware, dubbed Roaming Mantis , hackers have been hijacking DNS settings on vulnerable and poorly secured routers . DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more. Hijacking routers' DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher —both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers. Discovered by security researchers at Kaspersk

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

Microsoft on Tuesday released fixes for 58 newly discovered security flaws spanning as many as 11 products and services as part of its final  Patch Tuesday of 2020 , effectively bringing their CVE total to 1,250 for the year. Of these 58 patches, nine are rated as Critical, 46 are rated as Important, and three are rated Moderate in severity. The December security release addresses issues in Microsoft Windows, Edge browser, ChakraCore, Microsoft Office, Exchange Server, Azure DevOps, Microsoft Dynamics, Visual Studio, Azure SDK, and Azure Sphere. Fortunately, none of these flaws this month have been reported as publicly known or being actively exploited in the wild. The fixes for December concern a number of remote code execution (RCE) flaws in Microsoft Exchange (CVE-2020-17132), SharePoint (CVE-2020-17118 and CVE-2020-17121), Excel (CVE-2020-17123), and Hyper-V virtualization software (CVE-2020-17095), as well as a patch for a security feature bypass in Kerberos (CVE-2020-16996)

An analysis of over 70 billion DNS records has led to the discovery of a new sophisticated malware toolkit dubbed  Decoy Dog  targeting enterprise networks. Decoy Dog , as the name implies, is evasive and employs techniques like strategic domain aging and DNS query dribbling, wherein a series of queries are transmitted to the command-and-control (C2) domains so as to not arouse any suspicion. "Decoy Dog is a cohesive toolkit with a number of highly unusual characteristics that make it uniquely identifiable, particularly when examining its domains on a DNS level," Infoblox  said  in an advisory published late last month. The cybersecurity firm, which identified the malware in early April 2023 following anomalous DNS beaconing activity, said its atypical characteristics allowed it to map additional domains that are part of the attack infrastructure. That said, the usage of Decoy Dog in the wild is "very rare," with the DNS signature matching less than 0.0000027%

Google on Tuesday officially announced support for DNS-over-HTTP/3 (DoH3) for Android devices as part of a Google Play system update designed to keep DNS queries private. To that end, Android smartphones running Android 11 and higher are expected to use DoH3 instead of DNS-over-TLS ( DoT ), which was incorporated into the mobile operating system with Android 9.0. DoH3 is also an alternative to DNS-over-HTTPS ( DoH ), a mechanism for carrying out remote Domain Name System (DNS) resolution through an encrypted connection, effectively preventing third parties from snooping on users' browsing activities. HTTP/3 , the first major upgrade to the hypertext transfer protocol since HTTP/2 was introduced in May 2015, is designed to use a new transport layer protocol called  QUIC  that's already supported by major browsers such as Google Chrome, Microsoft Edge, Mozilla Firefox, and Apple Safari. The low-latency protocol, developed by Google in 2012, relies on the User Datagram Prot
