World's largest 1 Tbps DDoS Attack launched from 152,000 hacked Smart Devices

World's largest 1 Tbps DDoS Attack launched from 152,000 hacked Smart Devices

Sep 28, 2016
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 (
602 Gbps! This May Have Been the Largest DDoS Attack in History

602 Gbps! This May Have Been the Largest DDoS Attack in History

Jan 09, 2016
Cyber attacks are getting evil and worst nightmare for companies day-by-day, and the Distributed Denial of Service (DDoS) attack is one of the favorite weapon for hackers to temporarily suspend services of a host connected to the Internet. Until now, nearly every big website had been a victim of this attack, and the most recent one was conducted against the BBC 's websites and Republican presidential candidate Donald Trump 's main campaign website over this past holiday weekend. Out of two, the largest DDoS attack in the history was carried out against the BBC website: Over 600 Gbps . Largest DDoS Attack in the History The group calling itself New World Hacking claimed responsibility for taking down both the BBC's global website and Donald Trump's website last week. The group targeted all BBC sites, including its iPlayer on-demand service, and took them down for at least three hours on New Year's Eve. At the moment, the BBC news organiz
Code Keepers: Mastering Non-Human Identity Management

Code Keepers: Mastering Non-Human Identity Management

Apr 12, 2024DevSecOps / Identity Management
Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or
ProtonMail Paid Hackers $6000 Ransom in Bitcoin to Stop DDoS Attacks

ProtonMail Paid Hackers $6000 Ransom in Bitcoin to Stop DDoS Attacks

Nov 06, 2015
The Geneva-based encrypted email service ProtonMail was forced to pay a  Ransom of almost $6,000 to stop sustained Denial-of-service (DDoS) attacks that have knocked its service offline since Tuesday. ProtonMail – a full, end-to-end encrypted email service that launched last year – has been dealing with, what it called, the extremely powerful DDoS attack, and is still unavailable at the time of writing. ProtonMail Paid $6,000 to Stop DDoS In an official statement posted on a WordPress blog Thursday, officials of ProtonMail said the powerful DDoS attack by an unknown group of hackers forced them to pay 15 Bitcoins (about $5,850) in exchange for them halting the assault. However, even after paying the ransom amount, the crippling DDoS attacks continued to the ProtonMail service. DDoS Attack Continues Even After Paying Ransom ProtonMail officials said, "We hoped that by paying [ransom], we could spare other companies impacted by the [DDoS] attack again

More Insights On Alleged DDoS Attack Against Liberia Using Mirai Botnet

More Insights On Alleged DDoS Attack Against Liberia Using Mirai Botnet

Nov 05, 2016
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
Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Alert: OracleIV DDoS Botnet Targets Public Docker Engine APIs to Hijack Containers

Nov 14, 2023 Cloud Security / Malware
Publicly-accessible Docker Engine API instances are being targeted by threat actors as part of a campaign designed to co-opt the machines into a distributed denial-of-service (DDoS) botnet dubbed  OracleIV . "Attackers are exploiting this misconfiguration to deliver a malicious Docker container, built from an image named 'oracleiv_latest' and containing Python malware compiled as an ELF executable," Cado researchers Nate Bill and Matt Muir  said . The malicious activity starts with attackers using an HTTP POST request to Docker's API to retrieve a malicious image from Docker Hub, which, in turn, runs a command to retrieve a shell script (oracle.sh) from a command-and-control (C&C) server. Oracleiv_latest  purports to be a MySQL image for docker and has been pulled 3,500 times to date. In a perhaps not-so-surprising twist, the image also includes additional instructions to fetch an XMRig miner and its configuration from the same server. That said, the clo
5 Major Russian Banks Hit With Powerful DDoS Attacks

5 Major Russian Banks Hit With Powerful DDoS Attacks

Nov 11, 2016
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
DDoS Extortionists made $100,000 without Launching a Single Attack

DDoS Extortionists made $100,000 without Launching a Single Attack

Apr 26, 2016
In Brief Cyber crooks find a new and ingenious way to make hundreds of thousands of dollars with no effort. An unknown cyber gang, pretending to be Armada Collective , has made more than $100,000 in less than two months simply by threatening to launch DDoS attack on websites, but never actually launched a single attack. A group of Cyber Extortionists is sending threatening emails to businesses across the globe involves the launching of powerful distributed denial-of-service (DDoS) attacks against victim's website unless a ransom is paid. But, the group never actually launched a single DDoS attack. In a typical scenario, attackers disrupt a targeted website with a short-term DDoS attack in order to demonstrate its power, followed by an e-mail containing ransom note threatening further disruption, if the ransom does not get paid. Armada Collective is the same criminal gang that was responsible for one of largest DDoS attacks against ProtonMail in November 2015 and ext
Massive HTTP DDoS Attack Hits Record High of 71 Million Requests/Second

Massive HTTP DDoS Attack Hits Record High of 71 Million Requests/Second

Feb 14, 2023
Web infrastructure company Cloudflare on Monday disclosed that it thwarted a record-breaking distributed denial-of-service (DDoS) attack that peaked at over 71 million requests per second (RPS). "The majority of attacks peaked in the ballpark of 50-70 million requests per second (RPS) with the largest exceeding 71 million," the company  said , calling it a "hyper-volumetric" DDoS attack. It's also the largest HTTP DDoS attack reported to date, more than 35% higher than the previous 46 million RPS DDoS attack that  Google Cloud mitigated in June 2022 . Cloudflare said the attacks singled out websites secured by its platform and that they emanated from a botnet comprising more than 30,000 IP addresses that belonged to "numerous" cloud providers. Targeted websites included a popular gaming provider, cryptocurrency companies, hosting providers, and cloud computing platforms. HTTP attacks of this kind are designed to send a tsunami of HTTP requests t

Vulnerability Allows Anyone to DDoS Websites Using Facebook Servers

Apr 25, 2014
Reading a 'Note' created by anyone on the Facebook could trick you automatically to do malicious attacks against others unknowingly. A Security researcher Chaman Thapa, also known as chr13 claims that the flaw resides in 'Notes' section of the most popular social networking site - Facebook, that could allow anyone to launch the distributed denial-of-service (DDoS) attack of more than 800 Mbps Bandwidth on any website. A Distributed Denial-of-Service (DDoS) attack is one in which multiple compromised systems attacks a single target system or service to make it unavailable to its intended users. The flood of incoming requests essentially forces the target system or service to shut down, thereby denying service to the system to its legitimate users. While demonstrating the vulnerability on his blog , he explained that Facebook allows its users to include tags inside the post in order to draft a note with beautiful related images from any source.

Friday's Massive DDoS Attack Came from Just 100,000 Hacked IoT Devices

Oct 27, 2016
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

Cloudflare Saw Record-Breaking DDoS Attack Peaking at 26 Million Request Per Second

Jun 15, 2022
Cloudflare on Tuesday disclosed that it had acted to prevent a record-setting 26 million request per second (RPS) distributed denial-of-service (DDoS) attack last week, making it the largest HTTPS DDoS attack detected to date. The web performance and security company said the attack was directed against an unnamed customer website using its Free plan and emanated from a "powerful" botnet of 5,067 devices, with each node generating approximately 5,200 RPS at peak. The botnet is said to have created a flood of more than 212 million HTTPS requests within less than 30 seconds from over 1,500 networks in 121 countries, including Indonesia, the U.S., Brazil, Russia, and India. Roughly 3% of the attack came through Tor nodes. The attack "originated mostly from Cloud Service Providers as opposed to Residential Internet Service Providers, indicating the use of hijacked virtual machines and powerful servers to generate the attack — as opposed to much weaker Internet of Things
DDoS Attack Takes Down Central Heating System Amidst Winter In Finland

DDoS Attack Takes Down Central Heating System Amidst Winter In Finland

Nov 09, 2016
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

IoT Botnet — 25,000 CCTV Cameras Hacked to launch DDoS Attack

Jun 28, 2016
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
Imperva Thwarts 2.5 Million RPS Ransom DDoS Extortion Attacks

Imperva Thwarts 2.5 Million RPS Ransom DDoS Extortion Attacks

Mar 05, 2022
Cybersecurity company Imperva on Friday said it recently mitigated a ransom distributed denial-of-service (DDoS) attack targeting an unnamed website that peaked at 2.5 million requests per second (RPS). "While ransom DDoS attacks are not new, they appear to be evolving and becoming more interesting with time and with each new phase," Nelli Klepfish, security analyst at Imperva,  said . "For example, we've seen instances where the ransom note is included in the attack itself embedded into a URL request." The top sources of the attacks came from Indonesia, followed by the U.S., China, Brazil, India, Colombia, Russia, Thailand, Mexico, and Argentina. Distributed denial-of-service (DDoS) attacks are a subcategory of denial-of-service (DoS) attacks in which an army of connected online devices, known as a botnet, is used to overwhelm a target website with fake traffic in an attempt to render it unavailable to legitimate users. The California-headquartered firm s
Docker Images Containing Cryptojacking Malware Distributed via Docker Hub

Docker Images Containing Cryptojacking Malware Distributed via Docker Hub

Jun 25, 2020
With Docker gaining popularity as a service to package and deploy software applications, malicious actors are taking advantage of the opportunity to target exposed API endpoints and craft malware-infested images to facilitate distributed denial-of-service (DDoS) attacks and mine cryptocurrencies. According to a report published by Palo Alto Networks' Unit 42 threat intelligence team, the purpose of these Docker images is to generate funds by deploying a cryptocurrency miner using Docker containers and leveraging the Docker Hub repository to distribute these images. "Docker containers provide a convenient way for packaging software, which is evident by its increasing adoption rate," Unit 42 researchers said . "This, combined with coin mining, makes it easy for a malicious actor to distribute their images to any machine that supports Docker and instantly starts using its compute resources towards cryptojacking." Docker is a well-known platform-as-a-servic

DDOS attack on Change.org from China !

Apr 20, 2011
DDOS attack on Change.org from China ! Change.org, an online petitioning platform, has come under an ongoing distributed denial of service (DDoS) attack originating from China after the site hosted a call urging Chinese authorities to release artist Ai Weiwei from custody. The attacks, which started late Sunday, have nearly brought down the site, according to Change.org founder Ben Rattray. DDoS attacks work by using hundreds or thousands of hacked computers to send traffic to a website, overwhelming it with data so it becomes inaccessible to normal users. Change.org said the current attack originates from an expanding group of computers primarily based in China, and has yet to stop. This is the first time the site has been hit with a DDoS attack. Change.org has been hosting a online petition calling for the release of Chinese artist Ai Weiwei, who is currently under arrest. The petition has attracted almost 100,000 people from 175 countries, making it one of Change.org'
Memcached Servers Abused for Massive Amplification DDoS Attacks

Memcached Servers Abused for Massive Amplification DDoS Attacks

Feb 28, 2018
Cybercriminals have figured out a way to abuse widely-used Memcached servers to launch over 51,000 times powerful DDoS attacks than their original strength, which could result in knocking down of major websites and Internet infrastructure. In recent days, security researchers at Cloudflare , Arbor Networks , and Chinese security firm Qihoo 360 noticed that hackers are now abusing "Memcached" to amplify their DDoS attacks by an unprecedented factor of 51,200. Memcached is a popular open-source and easily deployable distributed caching system that allows objects to be stored in memory and has been designed to work with a large number of open connections. Memcached server runs over TCP or UDP port 11211. The Memcached application has been designed to speed up dynamic web applications by reducing stress on the database that helps administrators to increase performance and scale web applications.
