Note — We have published  an updated article on what really happened behind the alleged DDoS attack against Liberia using Mirai botnet. Someone is trying to take down the whole Internet of a country, and partially succeeded, by launching massive distributed denial-of-service (DDoS) attacks using a botnet of insecure IoT devices infected by the Mirai malware. It all started early October when a cyber criminal publicly released the source code of Mirai – a piece of nasty IoT malware designed to scan for insecure IoT devices and enslaves them into a botnet network, which is then used to launch DDoS attacks. Just two weeks ago, the Mirai IoT Botnet caused vast internet outage by launching massive DDoS attacks against DNS provider Dyn, and later it turns out that just 100,000 infected-IoT devices participated in the attacks. Experts believe that the future DDoS attack could reach 10 Tbps, which is enough to take down the whole Internet in any nation state. One such inciden

The whole world is still dealing with the Mirai IoT Botnet that caused vast internet outage last Friday by launching massive distributed denial of service (DDoS) attacks against the DNS provider Dyn, and researchers have found another nasty IoT botnet. Security researchers at MalwareMustDie have discovered a new malware family designed to turn Linux-based insecure Internet of Things (IoT) devices into a botnet to carry out massive DDoS attacks. Dubbed Linux/IRCTelnet , the nasty malware is written in C++ and, just like Mirai malware , relies on default hard-coded passwords in an effort to infect vulnerable Linux-based IoT devices. The IRCTelnet malware works by brute-forcing a device's Telnet ports, infecting the device's operating system, and then adding it to a botnet network which is controlled through IRC (Internet Relay Chat) – an application layer protocol that enables communication in the form of text. So, every infected bot (IoT device) connects to a mali

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

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

Guess how many devices participated in last Friday's massive DDoS attack against DNS provider Dyn that caused vast internet outage? Just 100,000 devices. I did not miss any zeros. Dyn disclosed on Wednesday that a botnet of an estimated 100,000 internet-connected devices was hijacked to flood its systems with unwanted requests and close down the Internet for millions of users. Dyn executive vice president Scott Hilton has issued a statement , saying all compromised devices have been infected with a notorious Mirai malware that has the ability to take over cameras, DVRs, and routers. "We're still working on analyzing the data but the estimate at the time of this report is up to 100,000 malicious endpoints," Hilton said. "We are able to confirm that a significant volume of attack traffic originated from Mirai-based botnets." Mirai malware scans for Internet of Things (IoT) devices that are still using their default passwords and then enslaves those

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

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

Are your internet-connected devices spying on you? Perhaps. We already know that the Internet of Thing (IoT) devices are so badly insecure that hackers are adding them to their botnet network for launching Distributed Denial of Service (DDoS) attacks against target services. But, these connected devices are not just limited to conduct DDoS attacks ; they have far more potential to harm you. New research [ PDF ] published by the content delivery network provider Akamai Technologies shows how unknown threat actors are using a 12-year-old vulnerability in OpenSSH to secretly gain control of millions of connected devices. The hackers then turn, what researchers call, these " Internet of Unpatchable Things " into proxies for malicious traffic to attack internet-based targets and 'internet-facing' services, along with the internal networks that host them. Unlike recent attacks via Mirai botnet , the new targeted attack, dubbed SSHowDowN Proxy , specifically ma

If you are concerned about the insecurity of Internet of Things, have good hands at programming and know how to hack smart devices, then you can grab an opportunity to earn $50,000 in prize money for discovering the non-traditional ways to secure IoT devices. Internet of Things (IoT) market is going to expand rapidly over the next decade. We already have 6.5 billion to 8 billion IoT devices connected to the Internet worldwide, and the number is expected to reach 50 billion by 2020. While IoT is going to improve life for many, the number of security risks due to lack of stringent security measures and encryption mechanisms in the devices have increased exponentially. This rise in the number of security risks would continue to widen the attack surface, giving hackers a large number of entry points to affect you some or the other way. Recently, we saw a record-breaking DDoS attack (Distributed Denial of Service) against the France-based hosting provider OVH that reached over

With rapidly growing Internet of Thing (IoT) devices, they have become a much more attractive target for cybercriminals. Just recently we saw a record-breaking Distributed Denial of Service (DDoS) attacks against the France-based hosting provider OVH that reached over one Terabit per second (1 Tbps), which was carried out via a botnet of infected IoT devices. Now, such attacks are expected to grow more rapidly as someone has just released the source code for IoT botnet, which was 'apparently' used to carry out world's largest DDoS attacks. Internet of Things-Botnet 'Mirai' Released Online Dubbed Mirai , the malware is a DDoS Trojan that targets BusyBox systems , a collection of Unix utilities specifically designed for embedded devices like routers. The malware is programmed to hijack connected IoT devices that are using the default usernames and passwords set by the factory before devices are first shipped to customers. Spotted by Brian Krebs , the

Do you know — Your Smart Devices may have inadvertently participated in a record-breaking largest cyber attack that Internet has just witnessed. If you own a smart device like Internet-connected televisions, cars, refrigerators or thermostats, you might already be part of a botnet of millions of infected devices that was used to launch the biggest DDoS attack known to date, with peaks of over 1 Tbps of traffic. France-based hosting provider OVH was the victim to the record-breaking Distributed Denial of Service (DDoS) attacks that reached over one terabit per second (1 Tbps) over the past week. As the Internet of Things (IoT) or connected devices are growing at a great pace, they continue to widen the attack surface at the same time, giving attackers a large number of entry points to affect you some or the other way. 1 Tbps DDoS Attack Hits OVH IoTs are currently being deployed in a large variety of devices throughout your home, businesses, hospitals, and even entire cities (

Internet of Things (IoT) is the latest buzz in the world of technology, but they are much easier to hack than you think. Until now we have heard many scary stories of hacking IoT devices , but how realistic is the threat? Just think of a scenario where you enter in your house, and it's sweltering, but when you head on to check the temperature of your thermostat, you find out that it has been locked to 99 degrees. And guess what? Your room thermostat is demanding $300 in Bitcoins to regain its control. Congratulations, Your Thermostat has been Hacked! This is not just a hypothetical scenario; this is exactly what Ken Munro and Andrew Tierney of UK-based security firm Pen Test Partners have demonstrated at the DEFCON 24 security conference in Las Vegas last Saturday. Two white hat hackers recently showed off the first proof-of-concept (PoC) ransomware that infects a smart thermostat. Ransomware is an infamous piece of malware that has been known for locking up comput

The Internet of things or connected devices are the next big concerns, as more Internet connectivity means more access points which mean more opportunities for hackers. When it comes to the threat to Internet of Things, Car Hacking is a hot topic. Since many automobiles companies are offering cars that run mostly on the drive-by-wire system, a majority of functions are electronically controlled, like instrument cluster, steering, brakes, and accelerator. No doubt these auto-control systems in vehicles improve your driving experience, but at the same time increase the risk of getting hacked. Recently, security researcher Benjamin Kunz Mejri  have disclosed zero-day vulnerabilities that reside the official BMW web domain and ConnectedDrive portal and the worst part: the vulnerabilities remain unpatched and open for hackers. Benjamin from Vulnerability-Labs has discovered both the vulnerabilities. The first one is a VIN ( Vehicle Identification Number ) session vulnerabil

The Internet of Things (IoTs) or Internet-connected devices are growing at an exponential rate and so are threats to them. Due to the insecure implementation, these Internet-connected embedded devices, including Smart TVs, Refrigerators, Microwaves, Set-top boxes, Security Cameras and printers, are routinely being hacked and used as weapons in cyber attacks. We have seen how hackers literally turned more than 100,000 Smart TVs and Refrigerator into the cyber weapon to send out millions of malicious spam emails for hacking campaigns; we have also seen how hackers abused printers and set-top-boxes to mine Bitcoins. And now… Cyber crooks are hacking CCTV cameras to form a massive botnet that can blow large websites off the Internet by launching Distributed Denial-of-service (DDoS) attacks. Researchers at Security firm Sucuri came across a botnet of over 25,000 CCTV cameras targeting business around the globe while defending a small jewelry shop against a DDoS attack . Al

Do you own a Smartwatch, Smart TV, Smart fridge, or any Internet-connected smart device? If your answer is yes, then you need to know the latest interest of the cyber criminals in the field of Internet of Things. Ransomware! After targeting hospitals, universities, and businesses, Ransomware has started popping up on Smart TV screens. A new version of the Frantic Locker (better known as FLocker ) Ransomware has now the ability to infect and lock down your Smart TVs until you pay up the ransom. Researchers at Trend Micro have discovered the updated version of FLocker that is capable of locking Android smartphones as well as Smart TVs . Originally launched in May 2015, the FLocker ransomware initially targeted Android smartphones with its developers constantly updating the ransomware and adding support for new Android system changes. Here's what the new version of FLocker does to your Android-powered Smart TVs: FLocker locks the device's screen. Displays a

The cyber attack vectors available to hackers will continue to grow as the Internet of Things (IoTs) become more commonplace, making valuable data accessible through an ever-widening selection of entry points. Although it's not the hackers alone, the NSA is also behind the Internet of Things. We already know the United States National Security Agency's (NSA) power to spy on American as well as foreign people – thanks to the revelations made by whistleblower Edward Snowden in 2013. But, now the agency is looking for new ways to collect even more data on foreign intelligence, and for this, the NSA is researching the possibilities of exploiting internet-connected biomedical devices ranging from thermostats to pacemakers. During a military technology conference in Washington D.C. on Friday, NSA deputy director Richard Ledgett said his agency officials are "looking at it sort of theoretically from a research point of view right now." Ledgett totally agreed o

Anything connected to the Internet could be hacked and so is the Internet of Things (IoTs) . The market fragmentation of IoTs or Internet-connected devices is a security nightmare, due to poor security measures implemented by their vendors. Now, the researchers at security firm ESET have discovered a piece of Malware that is targeting embedded devices such as routers, and other connected devices like gateways and wireless access points, rather than computers or smartphones. Dubbed KTN-Remastered or KTN-RM , the malware is a combination of both Tsunami (or Kaiten) as well as Gafgyt. Tsunami is a well-known IRC ( Internet Relay Chat ) bot used by miscreants for launching Distributed Denial of Service (DDoS) attacks while Gafgyt is used for Telnet scanning. KTN-RM, which researcher dubbed ' Remaiten ,' features an improved spreading mechanism by carrying downloader executable binaries for embedded platforms and other connected devices. How Does the

Do you know that your daily household items can be turned into deadly weapons? Yes, it's possible to convert some of your everyday household appliances into explosives, weapons or surveillance devices. DARPA – the agency which does research in various fields for improving the US Military and US Department of Defense capabilities – had announced a new project dubbed " Improv " to transform simple household appliances into deadly weapons i.e. homemade weapons. In previous years, various military grade weapons had been found malfunctioned by the ordinary household things that could cripple the military inventions. By various incidents happening around the Military grounds, officials observed that "how easily-accessed hardware, software, processes, and methods could be used to create products or systems that could pose a future threat." So, DARPA ( Defense Advanced Research Projects Agency ) proceeded with a program and is seeking proposals

More than a Billion of Android devices are at risk of a severe vulnerability in Qualcomm Snapdragon chip that could be exploited by any malicious application to gain root access on the device. Security experts at Trend Micro are warning Android users of some severe programming blunders in Qualcomm's kernel-level Snapdragon code that if exploited, can be used by attackers for gaining root access and taking full control of your device. Gaining root access on a device is a matter of concern, as it grants attackers access to admin level capabilities, allowing them to turn your device against you to snap your pictures, and snoop on your personal data including accounts' passwords, emails, messages and photos. The company's own website notes that Qualcomm Snapdragon SoCs (systems on a chip) power more than a Billion smart devices, including many Internet of Things (IoTs) as of today. Thus, the issue puts many people at risk of being attacked. Although Google has pus
