Memcached DDoS Exploit Code and List of 17,000 Vulnerable Servers Released

Memcached DDoS Exploit Code and List of 17,000 Vulnerable Servers Released
March 07, 2018Swati Khandelwal
Two separate proofs-of-concept (PoC) exploit code for Memcached amplification attack have been released online that could allow even script-kiddies to launch massive DDoS attacks using UDP reflections easily. The first DDoS tool is written in C programming language and works with a pre-compiled list of vulnerable Memcached servers. Bonus—its description already includes a list of nearly 17,000 potential vulnerable Memcached servers left exposed on the Internet. Whereas, the second Memcached DDoS attack tool is written in Python that uses Shodan search engine API to obtain a fresh list of vulnerable Memcached servers and then sends spoofed source UDP packets to each server. Last week we saw two record-breaking DDoS attacks— 1.35 Tbps hit Github and 1.7 Tbps attack against an unnamed US-based company—which were carried out using a technique called amplification/reflection attack. For those unaware, Memcached-based amplification/reflection attack amplifies bandwidth of th

Unpatched DoS Flaw Could Help Anyone Take Down WordPress Websites

Unpatched DoS Flaw Could Help Anyone Take Down WordPress Websites
February 05, 2018Mohit Kumar
A simple yet serious application-level denial of service (DoS) vulnerability has been discovered in WordPress CMS platform that could allow anyone to take down most WordPress websites even with a single machine—without hitting with a massive amount of bandwidth, as required in network-level DDoS attacks to achieve the same. Since the company has denied patching the issue, the vulnerability ( CVE-2018-6389 ) remains unpatched and affects almost all versions of WordPress released in last nine years, including the latest stable release of WordPress (Version 4.9.2). Discovered by Israeli security researcher Barak Tawily , the vulnerability resides in the way " load-scripts.php ," a built-in script in WordPress CMS, processes user-defined requests. For those unaware, load-scripts.php file has only been designed for admin users to help a website improve performance and load page faster by combining (on the server end) multiple JavaScript files into a single request.

Three Hackers Plead Guilty to Creating IoT-based Mirai DDoS Botnet

Three Hackers Plead Guilty to Creating IoT-based Mirai DDoS Botnet
December 13, 2017Mohit Kumar
The U.S. federal officials have arrested three hackers who have pleaded guilty to computer-crimes charges for creating and distributing Mirai botnet that crippled some of the world's biggest and most popular websites by launching the massive DDoS attacks last year. According to the federal court documents unsealed Tuesday, Paras Jha (21-year-old from New Jersey), Josiah White (20-year-old Washington) and Dalton Norman (21-year-old from Louisiana) were indicted by an Alaska court last week on multiple charges for their role in massive cyber attacks conducted using Mirai botnet. Mirai is a piece of nasty IoT malware that scans for insecure routers, cameras, DVRs, and other Internet of Things devices which are still using their default passwords and then add them into a botnet network, which is then used to launch DDoS attacks on websites and Internet infrastructure. According to his plea agreement, Jha " conspired to conduct DDoS attacks against websites and web ho

Europol has announced that the law enforcement agencies from 13 countries around the globe have arrested 34 users of Netspoof DDoS attack tool and interviewed and warned 101 suspects in a global crackdown. According to the report published on the official website of Europol, law enforcement authorities worldwide have made the arrest between 5 December and 9 December 2016. Europol's European Cybercrime Centre (EC3) supported the law enforcement agencies in their efforts to identify suspects in the European Union and beyond. Arrested Suspects Are Mainly Teenagers All those arrested are mainly "young adults under the age of 20," who are suspected of paying for Netspoof stresser as well as booters services to maliciously deploy DDoS-for-hire software and using them to launch cyber attacks. The ddos attacks flooded target websites and web servers with massive amounts of data, leaving those services inaccessible to users. Europol's European Cybercrime Cent

Mirai Botnet Itself is Flawed; Hacking Back IoTs Could Mitigate DDoS Attacks

Mirai Botnet Itself is Flawed; Hacking Back IoTs Could Mitigate DDoS Attacks

The infamous botnet that was used in the recent massive distributed denial of service (DDoS) attacks against the popular DNS provider Dyn, causing vast internet outage  last Friday, itself is flawed. Yes, Mirai malware, which has already enslaved millions of Internet of Things (IoT) devices across 164 countries, contains several vulnerabilities that might be used against it in order to destroy botnet's DDoS capabilities and mitigate future attacks. Early October, the developer of the malware publically released the source code of Mirai , which is designed to scan for IoT devices – mostly routers, cameras, and DVRs – that are still using their default passwords and then enslaves them into a botnet, which is then used to launch DDoS attacks. However, after a close look at the source code, a researcher discovered three vulnerabilities, one of which could be used to shut down Mirai's ability to flood targets with HTTP requests. A stack buffer overflow vulnerability wa

You might be surprised to know that your security cameras, Internet-connected toasters and refrigerators may have inadvertently participated in the massive cyber attack that broke a large portion of the Internet on Friday. That's due to massive Distributed Denial of Service (DDoS) attacks against Dyn, a major domain name system (DNS) provider that many sites and services use as their upstream DNS provider for turning IP addresses into human-readable websites. The result we all know: Twitter, GitHub, Amazon, Netflix, Pinterest, Etsy, Reddit, PayPal, and AirBnb, were among hundreds of sites and services that were rendered inaccessible to Millions of people worldwide for several hours. Why and How the Deadliest DDoS Attack Happened It was reported that the Mirai bots were used in the massive DDoS attacks against DynDNS, but they "were separate and distinct" bots from those used to execute record-breaking DDoS attack against French Internet service and hosting

Six British teenagers arrested and released on bail on suspicion of launching cyber attacks on websites and services with the help of Lizard Squad DDoS attack tool, called Lizard Stresser . Lizard Squad is infamous for hacking and knocking down the largest online gaming networks – PlayStation Network and Xbox Live – last year by launching massive Distributed Denial-of-Service (DDoS) attacks. The notorious hacker group set up a website to let customers use its Lizard-branded DDoS-for-hire tool Lizard Stresser to launch similar DDoS attacks. The six teens, arrested by the National Crime Agency , are accused of using Lizard Stresser DDoS tool to launch cyber attacks against a school, a national newspaper, gaming companies and a number of online retailers. However, according to the law enforcement, none of the teenagers are believed to be the member of Lizard Squad, nor had any connection with the last year's Christmas hack against Sony and Microsoft's gami

China Using A Powerful 'Great Cannon' Weapon to Censor The Internet
April 11, 2015Swati Khandelwal
China has something very impressive that we are not aware of. The country has a powerful and previously unknown weapon that its government is using to bolster their cyber attack capabilities: Dubbed " The Great Cannon. " INTERNET CENSORSHIP IN CHINA When I talk about Internet censorship, it is incomplete if I don't mention China. China is famous for its Great Wall of China and Great Firewall of China . The censoring of Internet access and blocking an individual website in China by its government, known as the Great Firewall of China. But, why the Chinese government does that? The answer is very simple: The Chinese government restricts those contents it deems sensitive for its country's so-called democracy. It illegalize certain online speech and activities, block selected websites, and filter keywords out of searches initiated from computers located in Mainland China. The worse: Those Chinese citizens who offend authorities against Int
