ddos attack | Breaking Cybersecurity News | The Hacker News

The Dutch hacker, who in 2013 was accused of launching the biggest cyberattack to date against the anti-spam group Spamhaus, escaped prison Monday even after he was sentenced to nearly 8 months in jail because most of his term was suspended. Sven Olaf Kamphuis , 39, was arrested in April 2013 by Spanish authorities in Barcelona based on a European arrest warrant for launching massive distributed denial of service (DDoS) attack against Spamhaus that peaked at over 300 Gbps. Spamhaus is a non-profit group based in Geneva and London that tracks spam and cyber-related threats, creates blacklists of those sites and then sells them to Internet Service Providers. However, the DDoS attacks on the company were so sustained that put "the proper functioning of the Internet at risk and thus the interests of many individuals, businesses and institutions," said the court. Kamphuis was initially sentenced to a total of 240 days, but he has already served 55 days in on remand aft

Yes, you only need a single laptop with a decent internet connection, rather a massive botnet, to launch overwhelming denial of service (DoS) attacks in order to bring down major Internet servers and modern-day firewalls. Researchers at TDC Security Operations Center have discovered a new attack technique that lone attackers with limited resources (in this case, a laptop and at least 15Mbps of bandwidth) can use to knock large servers offline. Dubbed a BlackNurse attack or the low-rate " Ping of Death " attack, the technique can be used to launch several low-volume DoS attacks by sending specially formed Internet Control Message Protocol (ICMP) packets, or 'pings' that overwhelm the processors on server protected by firewalls from Cisco, Palo Alto Networks, among others. ICMP is a protocol used by routers and other networking devices to send and receive error messages. According to a technical report [ PDF ] published this week, the BlackNurse attack is mo

Imagine a world where the software that powers your favorite apps, secures your online transactions, and keeps your digital life could be outsmarted and taken over by a cleverly disguised piece of code. This isn't a plot from the latest cyber-thriller; it's actually been a reality for years now. How this will change – in a positive or negative direction – as artificial intelligence (AI) takes on a larger role in software development is one of the big uncertainties related to this brave new world. In an era where AI promises to revolutionize how we live and work, the conversation about its security implications cannot be sidelined. As we increasingly rely on AI for tasks ranging from mundane to mission-critical, the question is no longer just, "Can AI  boost cybersecurity ?" (sure!), but also "Can AI  be hacked? " (yes!), "Can one use AI  to hack? " (of course!), and "Will AI  produce secure software ?" (well…). This thought leadership article is about the latter. Cydrill  (a

Distributed Denial of Service (DDoS) attacks have risen enormously in past few months and, mostly, they are coming from hacked and insecure internet-connected devices, most commonly known as Internet of Things (IoT). Recent DDoS attack against DNS provider Dyn that brought down a large chunk of the Internet came from hacked and vulnerable IoT devices such as DVRs, security cameras, and smart home appliances. This DDoS was the biggest cyber attack the world has ever seen. Now, in the latest incident, at least five Russian banks have been subject to a swathe of DDoS attacks for two days, said the Russian banking regulator. The state-owned Sberbank was one of the five targets of the attacks that began on last Tuesday afternoon and lasted over the next two days. According to Kaspersky Lab, the longest attack last for 12 hours and peaked at 660,000 requests per second came from a botnet of at least 24,000 hacked devices located in 30 countries. Although the culprit appears

As announced on Tuesday, the OpenSSL project team released OpenSSL version 1.1.0c that addresses three security vulnerabilities in its software. The most serious of all is a heap-based buffer overflow bug (CVE-2016-7054) related to Transport Layer Security (TLS) connections using *-CHACHA20-POLY1305 cipher suites. The vulnerability, reported by Robert Święcki of the Google Security Team on September 25, can lead to DoS attack by corrupting larger payloads, resulting in a crash of OpenSSL. The severity of the flaw is rated "High" and does not affect OpenSSL versions prior to 1.1.0. However, the OpenSSL team reports there is no evidence that the flaw is exploitable beyond a DoS attack. The OpenSSL project also patches a moderate severity flaw (CVE-2016-7053) that can cause applications to crash. "Applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0

Just Imaging — What if, you enter into your home from a chilling weather outside, and the heating system fails to work because of a cyber attack, leaving you in the sense of panic? The same happened late last month when an attack knocks heating system offline in Finland. Last week, a Distributed Denial of Service (DDoS) attack led to the disruption of the heating systems for at least two housing blocks in the city of Lappeenranta, literally leaving their residents in subzero weather. Both the apartments are managed by a company called Valtia, a facilities services company headquartered in Lappeenranta. Valtia CEO Simo Rounela confirmed to English language news outlet Metropolitan.fi that the central heating system and hot water system in both buildings had become a target of DDoS attacks. In an attempt to fight back the cyber attacks, which lived for a short time, the automated systems rebooted — and unfortunately got stuck in an endless loop, which restarted repeatedly a

With just two days before the presidential election, WikiLeaks late Sunday night published a new trove of emails apparently hacked from the Democratic National Committee (DNC). The most recent dump of more than 8,000 emails came after the whistleblowing site, on a daily basis over last four weeks, has already leaked over 50,000 emails stolen from the key figure in the DNC – Hillary Clinton's campaign chairman John Podesta. However, this time, not everything went as planned by WikiLeaks. WikiLeaks early Monday morning announced on Twitter that shortly after the release of hacked DNC emails the organization was the target of a major Distributed Denial of Service (DDoS) attack. What's more?  Soon after WikiLeaks reported the DDoS attack on its email publication servers, Twitter also went down, and the outage lasts for at least 30 minutes. According to a status monitor, the Twitter outage began at around 6.45am GMT and continued for nearly half an hour, though report

On Thursday, we compiled a story based on research published by a British security expert reporting that some cyber criminals are apparently using Mirai Botnet to conduct DDoS attacks against the telecommunication companies in Liberia, a small African country. In his blog post , Kevin Beaumont claimed that a Liberian transit provider confirmed him about the DDoS attack of more than 500 Gbps targeting one undersea cable servicing Internet connectivity for the entire country. Later, some media outlets also confirmed that the DDoS attack caused Internet outage in some parts of the country, citing 'slow Internet' and 'total outage' experienced by some local sources and citizens. "The DDoS is killing our business. We have a challenge with the DDoS. We are hoping someone can stop it. It's killing our revenue. Our business has frequently been targeted" an employee with one Liberian mobile service provider told PC World . Network firm Level 3 confirmed Zack Whittaker

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

Due to the worldwide promotion of Mirai botnet that knocked down half of the Internet last Friday, hackers and even script kiddies have started creating their own botnet networks by hacking millions of IoT devices and selling them as DDoS-for-hire service to overwhelm targets with data. A 19-year-old student from Hertford has pled guilty to running one such DDoS-for-hire service that shortly became one of the most popular DDoS booter tools in the market to conduct distributed denial of service (DDoS) attacks. Dubbed Titanium Stresser , the tool was used to conduct coordinated DDoS attacks around the world and brought Adam Mudd an income of more than US$385,000 (£315,000 A$505,000), according to the Eastern Region Special Operations Unit (ERSOU). On 28 October at the Old Bailey, Mudd pleaded guilty to two counts of the Computer Misuse Act and one count of money laundering offense and will be sentenced in December. Mudd, who was arrested at his home in 2015, admitted to comm

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

Just last month, researchers explained how an attacker can knock the 911 service offline in an entire state by launching automated Distributed Denial of Service (DDoS) attacks using a botnet of just 6000 smartphones. But, doing so, in reality, could not only land public in danger but the attacker as well. The same happened to an 18-year-old teen from Arizona, who was arrested this week following a severe disruption of 911 emergency systems caused due to one of his iOS exploits. Meetkumar Hiteshbhai Desai discovered an iOS vulnerability that could be exploited to manipulate devices, including trigger pop-ups, open email, and abuse phone features, according to a press release from the Cyber Crimes Unit of Maricopa County Sheriff's Office. In order to prove the flaw, Desai allegedly created several exploits and posted a link to one of his JavaScript exploits on his Twitter account and other websites. People accessing the exploit link from their iPhones and iPads were

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

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

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 (

The OpenSSL Foundation has patched over a dozen vulnerabilities in its cryptographic code library, including a high severity bug that can be exploited for denial-of-service (DoS) attacks. OpenSSL is a widely used open-source cryptographic library that provides encrypted Internet connections using Secure Sockets Layer (SSL) or Transport Layer Security (TLS) for the majority of websites, as well as other secure services. The vulnerabilities exist in OpenSSL versions 1.0.1, 1.0.2 and 1.1.0 and patched in OpenSSL versions 1.1.0a, 1.0.2i and 1.0.1u. The Critical-rated bug ( CVE-2016-6304 ) can be exploited by sending a large OCSP Status Request extension on the targeted server during connection negotiations, which causes memory exhaustion to launch DoS attacks, the OpenSSL Project said . What is OCSP Protocol? OCSP (Online Certificate Status Protocol), supported by all modern web browsers, is a protocol designed to perform verification and obtain the revocation status of a digital
