DDoS prevention as part of a robust I.T. Strategy

A decade ago the idea of loss prevention (LP) had been limited to the idea of theft of merchandise. With the advent of online retailing, retailers have discovered that loss must be viewed more broadly to “intended sales income that was not and cannot be realized” [Beck and Peacock, 28]. While Beck and Peacock regard malicious loses such as vandalism as part of sales that cannot be realized, Distributed Denial of Service (DDoS) attacks certainly could fit with that definition. Unlike other kinds of LP, where the attempt of the thief is to conceal their activities, a DDoS attack is designed for maximal visibility so the purpose of the attack is to deny the target customer’s access, and especially susceptible are businesses that have online payment gateways [Gordon, 20] which today includes many business and non-profit entities. Particularly problematic for CIOs is that the nature of DDoS attacks is constantly changing. Many of these attacks occur at networking layers below the application level, which means for the CIO that buying an off-the-shelf software product is unlikely to provide an effective countermeasure [Oliveira et al, 19]. Of course, the determination of financial impact is an important consideration when weighing allocations of the IT security budget. While it is clear that the “loss of use and functionality” constitutes true losses to a company [Hovav and D’Arcy, 98], estimating a potential loss encounters difficulties given the lack of historical data and a perceived risk to putting an exact figure upon security breach losses. This presents a problem for the CIO because of the need to show ROI on security investments [Hovav and D’Arcy, 99]. Yet, a successful DDoS attack has the potential to cost a company millions of dollars in real financial losses from the direct costs of work time, equipment leases, and legal costs to the indirect costs, such as, loss of competitive advantage and damage done to the company’s brand. The direct cost of “a more complex breach that affects a cross-section of a complex organization” can often exceed £500,000 (624,000 USD) and does not include additional five or six figure fines if government regulatory agencies are involved [Walker and Krausz, 30]. If the CIO cannot buy an off-the-shelf software product to prepare against a DDoS attack, how does the CIO develop an I.T. security strategy that is appropriate to this specific threat? While this is by no means an exhaustive list: here are a few approaches that one can take that may help to developing an effective I.T. strategy that can deal with the DDoS threat. (1) Accept that developing an I.T. strategy effective against mitigating loss caused by DDoS requires resources, but your business is worth protecting. (2) Remember that the purpose of technology is to connect your business to people [Sharif, 348], and that connectivity is itself an asset that has real value. (3) Developing effective business partners can help you ensure business continuity. These partnerships could be with consultants, alliance partnerships that have successfully dealt with DDoS attacks, or businesses that specialize in dealing with this kind of security issue.

Protest Aims to ‘Take Down’ WhiteHouse.Gov on Inauguration Day

National PR service circulates—then pulls—release highlighting campaign to crash government website BY: Morgan Chalfant January 14, 2017 4:56 am A leading public-relations service blasted and then removed a news release this week highlighting a campaign to protest the inauguration of Donald Trump by crashing WhiteHouse.gov. PR Newswire, a global news-release distribution service, circulated a release on Thursday highlighting a campaign launched by Protester.io, a digital protest organizing platform, to “take down” the White House website next Friday in protest of Trump’s inauguration. “On January 20th, hundreds of thousands of Americans are going to Washington, DC to march in protest of the inauguration of Donald Trump. Millions more around the country will be joining the cause from home. If you can’t make it to Washington DC on inauguration day, you can still participate by occupying whitehouse.gov online,” the release read. “Why is it important to participate? Isn’t this just another election? We haven’t lost our democracy yet, but it is most definitely under threat. The only way we’re going to defend and revive our democracy is by mobilizing.” Protester.io describes itself as a platform that helps individuals “organize protests like a crowdfunding campaign.” A description of the Inauguration Day protest on its website, named “Occupy WhiteHouse.gov,” instructs interested parties to go to the White House website on Jan. 20 and refresh the page as often as possible throughout the day. The page also includes instructions for protesters to “automate” page refresh so that their computers do this automatically. “When enough people occupy www.WhiteHouse.gov the site will go down. Please join us and stand up against this demagogue who is threatening our democracy and our security,” the protest page states. Shortly after blasting the news release, PR Newswire issued a correction, changing the headline of the release from “Protester.io Launches Campaign to Take Down WhiteHouse.gov on Inauguration Day” to “Protester.io Launches Campaign to Voice Your Opinion at WhiteHouse.gov on Inauguration Day.” Later, the news-release service removed the press release entirely. PR Newswire was purchased by Cision, a global public relations software company based in Chicago, for $841 million from British business events organizer UBM in 2015. PR Newswire is based in New York and distributes public relations messages for companies largely located in the United States and Canada, according to the New York Times. When contacted, a spokesman for Cision confirmed to the Washington Free Beacon that the original release had been modified and later removed entirely “after further evaluation.” “The issuer modified the original release at our request, but after further evaluation, we ultimately decided to remove the release in its entirety and have requested that the rest of our network remove the content as well,” Stacey Miller, director of communication for Cision, wrote in an email Friday afternoon. An organizer for the protest did not respond to a request for comment. Federal investigators have probed what are called distributed denial of service, or DDoS, attacks, which block users from websites by overloading them with traffic. Such attacks brought down Twitter, Spotify, and Amazon last October, prompting investigations by the FBI and Department of Homeland Security. It is unclear whether the planned “Occupy WhiteHouse.gov” protest campaign would constitute a DDoS attack. Attempts to reach the FBI on Friday were unsuccessful. Several protests have been organized around Inauguration Day, including the “Women’s March on Washington” that is expected to draw some 200,000 women to the nation’s capital on Jan. 21, the day following Trump’s inauguration. Fox News reported that protesters are also planning to blockade security checkpoints at the inauguration and organize a “dance party” outside the home of Vice President-elect Mike Pence.

Three ways retailers can safeguard against cybercrime

Chinese New Year is always a shopping boom time in town. People are generous in spending on food, decorations, and fashion during the important cultural festival. While retailers are focused on ensuring that they successfully take advantage of spikes in online and in-store sales, are they as prepared as they need to be to defend against major distributed denial of service (DDoS) attacks? Avoiding a cyber-crime catastrophe Thanksgiving officially kicks off the biggest shopping period of the year globally. The period through to Chinese New Year may be a sales bonanza, but it’s also a period of high vulnerability that criminals exploit to maximize the threat to a retailer’s business. Along with gaming and finance companies, retailers are popular targets because they store sensitive data that thieves can use for financial gain. Additionally, DDOS attacks are often used to distract organizations so that even more costly web application attacks can take place at the same time. But the truth is no industry is immune and the threat is increasing in its relentlessness. With Chinese New Year sales accounting for a sizeable chunk of most retailers’ revenues, from a criminal’s perspective, there could hardly be a better time to launch a cyber attack. What’s more, with systems already creaking under a load of peak volumes, it might not take much of a straw to break the camel’s back. The last thing a retailer wants is for their business to spectacularly and very visibly come to a sudden halt because they can’t defend against and mitigate a major distributed denial of service (DDoS) attack. Retailers face a growing threat Talk of cyber attacks are more than mere scaremongering – the threat is very real. For example, in September, the release of the Mirai code — a piece of malware that infects IoT devices enabling them to be used for DDoS attacks — opened a Pandora’s box of opportunities for ruthless cyber entrepreneurs who want to disrupt their target markets and exploit the vulnerabilities and weaknesses of companies who honestly serve their customers. This code gives criminals the ability to orchestrate legions of unsecured Internet of Things (IoT) devices to act as unwitting participants in targeted DDoS attacks. These objects could be anything from domestic hubs and routers to printers and digital video recorders — as long as they’re connected to the internet. The latest large DDoS attacks have used botnets just like this — proving that the bad guys are multiplying and, most likely, gearing up for bigger things. Asia is not immune and Hong Kong is a prime target According to a recent report by Nexusguard, DDoS attacks increased 43 percent in Q2 to 34,000 attacks in the Asia-Pacific region and 83 percent worldwide. The largest increase was seen in Hong Kong, where attacks rose an astonishing 57 percent. China, which saw a 50% increase in attacks, is the number one target in the region. According to the report, over the course of a month, a Chinese website was attacked 41 times. The fact is, that every company needs to pay this issue serious attention and put effective plans in place. Prevention is the better than the cure There are no easy answers to the question of how to secure IoT smart devices — especially at the ‘budget conscious’ end of the market. That’s why we expect that these DDoS attacks will continue to proliferate, meaning that targeted DDoS attacks of increasing scale and frequency will almost certainly occur as a result. So how can retailers defend themselves against the threat of an attack? Organizations have to use a combination of measures to safeguard against even the most determined DDoS attack. This include: 1. Limiting the impact of an attack by absorbing DDoS traffic targeted at the application layer, deflecting all DDoS traffic targeted at the network layer and authenticating valid traffic at the network edge 2. Choosing an ISP that connects directly to large carriers and other networks, as well as internet exchanges — allowing traffic to pass efficiently 3. Employing the services of a network-based DDoS provider — with a demonstrable track record of mitigating DDoS attacks and sinking significant data floods. This will safeguard specific IP address ranges that organizations want to protect. Chinese New Year is a critical period for retailers — and hopefully for all the right reasons. But in an increasingly digital world, consideration needs to be given to the IT infrastructure that underpins today’s retail business and the security strategy that protects it.

Many businesses are relying on others to fight DDoS attacks

With large scale cyber attacks constantly hitting the headlines, businesses ought to be aware of the need to protect themselves. But a new study by Kaspersky Lab shows that 40 percent of businesses are unclear on how to protect themselves against targeted attacks and DDoS. Many believe that someone else will protect them and therefore don’t take their own security measures. 40 percent think their ISP will provide protection and 30 percent think data center or infrastructure partners will protect them. Moreover, the survey finds that 30 percent fail to take action because they think they are unlikely to be targeted by DDoS attacks. Surprisingly, 12 percent even admit to thinking that a small amount of downtime due to DDoS would not cause a major issue for the company. The reality of course is that any company can be targeted because such attacks are easy for cybercriminals to launch and the potential cost of a single attack can be millions. “As we’ve seen with the recent attacks, DDoS is extremely disruptive, and on the rise,” says Kirill Ilganaev, head of Kaspersky DDoS protection at Kaspersky Lab. “When hackers launch a DDoS attack, the damage can be devastating for the business that’s being targeted because it disables a company’s online presence. As a result business workflow comes to a halt, mission-critical processes cannot be completed and reputations can be ruined. Online services and IT infrastructure are just too important to leave unguarded. That’s why specialized DDoS protection solution should be considered an essential part of any effective protection strategy in business today”. The findings are based on Kaspersky Lab’s annual Corporate IT Security Risks survey conducted in cooperation with B2B International. In 2016, it surveyd more than 4,000 representatives of small, medium (50 to 999 employees) and large businesses (1000+) from 25 countries to find their views on IT security and the real incidents they had to deal with.

Trump must focus on cyber security

When Donald Trump takes the oath of office on Jan. 20, he’ll face an urgent and growing threat: America’s vulnerability to cyberattack. Some progress has been made in fortifying the nation’s digital defenses. But the U.S. is still alarmingly exposed as it leaps into the digital age. If the 45th president wants to make America great again, he needs to address this growing insecurity. Three areas — energy, telecommunications and finance — are especially vital and vulnerable. The government must commit itself to defending them. And it must recognize that the risks posed to all three are increasing as more and more parts of our lives are connected to the Internet. Start with energy. There is already malware prepositioned in our national power grid that could be used to create serious disruptions. It must be cleaned up. Last December, three of Ukraine’s regional power-distribution centers were hit by cyberattacks that caused blackouts affecting at least 250,000 citizens. The U.S. is just as vulnerable, because the malware used in that attack is widespread and well placed here. It would be a federal emergency if any region or city were to lose power for an extended period, and it could easily happen — taking down much of our critical infrastructure in the process. The government historically has taken steps to ensure the availability of communications in an emergency (for instance, the 911 system). It should do the same for power. In particular, Trump should direct the Federal Emergency Management Agency to use the Homeland Security Grant Program to improve cyber resilience at state and local power facilities. These efforts must be focused on removing malware and fielding better defenses, beginning with the highest-risk facilities crucial to the centers of our economic and political power. Next, protect telecommunications. The integrity our telecommunications system is essential for the free flow of goods, services, data and capital. Yet the U.S. is home to highest number of “botnets,” command-and-control servers and computers infected by ransomware in the world. Compromised computers are being used to launch paralyzing distributed denial of service (or DDoS) attacks against a wide range of companies. In October, such an attack knocked numerous popular services offline, including PayPal, Twitter, the New York Times, Spotify and Airbnb. Thousands of citizens and businesses were affected. To address this problem, the next president should start a national campaign to reduce the number of compromised computers plaguing our systems. This campaign should be managed like the Y2K program — the largely successful effort, led by the White House in tandem with the private sector, to fix a widespread computer flaw in advance of the millennium. With the same sense of urgency, the government should require that internet service providers give early warning of new infections and help their customers find and fix vulnerabilities. Just as water suppliers use chlorine to kill bacteria and add fluoride to make our teeth stronger, ISPs should be the front line of defense. Third, the U.S. must work with other countries to protect the global financial system. In recent years, financial institutions have experienced a wide range of malicious activity, ranging from DDoS attacks to breaches of their core networks, resulting in the loss of both money and personal information. In the past year, a number of breaches at major banks were caused by security weaknesses in the interbank messaging system known as SWIFT. The entire financial system is at risk until every connected institution uses better security, including tools to detect suspicious activities and hunt for the malicious software that enables our money to be silently stolen. The U.S. should work with China and Germany — the current and future leaders of the G-20 — to deploy better cyberdefenses, use payment-pattern controls to identify suspicious behavior and introduce certification requirements for third-party vendors to limit illicit activity. The Treasury Department should work with its global partners and U.S. financial institutions to set metrics and measure progress toward improving the trustworthiness and security of the financial ecosystem. All these problems, finally, may be exacerbated by the rise of the Internet of Things. As more and more devices are connected to the internet, it isn’t always clear who’s responsible for keeping them secure. Without better oversight, the Internet of Things will generate more botnets, command-and-control servers, and computers susceptible to ransomware. Flawed products will disrupt businesses, damage property and jeopardize lives. When medical devices can be subject to serious e-security flaws, and when vulnerable software in security cameras can be exploited to knock businesses off-line, government intervention is required. Manufacturers, retailers and others selling services and products with embedded digital technology must be held legally accountable for the security flaws of their wares. We need to put an end to the “patch Tuesday” approach of fixing devices after they’re widely dispersed. A better approach is an Internet Underwriters Laboratory, akin to the product-testing and certification system used for electrical appliances. Such a system could help ensure that internet-connected devices meet a minimum level of security before they’re released into the marketplace. Trump should make it clear in his first budget proposal that these four steps are vital priorities. The digital timer on our national security is ticking.

Group that attacked Tumblr threatens to DDoS Xbox for Christmas

A new hacking group is taking credit for a distributed denial-of-service (DDoS) attack that took down Tumblr this week. But so far, little is known about R.I.U. Star Patrol other than its motive of attacking for fun. Tumblr went down for more than two hours Wednesday afternoon and R.I.U. Star Patrol contacted Mashable to explain its reason for attacking: “There is no sinister motive,” the group told Mashable.”It’s all for light hearted fun.” The site was first reported offline shortly after 3:15pm ET. The service said on Twitter that some users were experiencing “latency”. Mashable reported that the site was back up for a few minutes around 3:52pm ET but went back down, returning at around 4:22pm ET. Full service was restored around 5:45pm ET. The Mirai connection Some in the security community believe the group carried out the attack using Mirai, malware tied to a record 620Gpbs attack on the website of noted journalist Brian Krebs and the coordinated assault against DNS hosting provider Dyn last fall. That DDoS crippled such major sites as Twitter, Paypal, Netflix and Reddit and shifted the world’s attention to threats against the so-called Internet of Things (IoT) – everyday devices and appliances connected to the web. What happened to Tumblr was a more typical DDoS, but it demonstrates how easy it has become to launch attacks since the source code for Mirai was openly published. In such attacks, a hacker attempts to overload or shut down a service so that legitimate users can no longer access it. Typical DoS attacks target web servers and aim to make websites unavailable. No data is stolen or compromised, but the interruption to the service can be costly for an organization. The most common type of DoS attack involves sending more traffic to a computer than it can handle. There are a variety of methods for DoS attacks, but the simplest and most common is to have a botnet flood a web server with requests. This is called a distributed denial-of-service attack (DDoS). What we know about R.I.U. Star Patrol so far A scouring of the internet produced few details about this hacking group. From what we can tell, its Twitter account (@StarPatrolling) came online on December 13 and that its self-described leader goes by the Twitter handle @ ANTIPEACESP . Gaming news site 7421Max conducted an interview with @StarPatrolling and published it on Youtube. Those interviewed said they plan to launch coordinated attacks against Xbox on Christmas day. Asked about their motive, the hackers said, “We do it because we can.” They claim they are not motivated by money. “We have not been paid a single dollar for what we do,” one of the hackers said. On December 19, 7421Max reported that the group had taken down League of Legends and Warframe servers, and warned in a follow-up tweet that R.I.U. Star Patrol plans to knock down PSN and Xbox Live for Christmas 2016. The group confirmed this in the Youtube video: The threat is going to sting for users who remember the Christmas 2014 DDoS blockage of PlayStation and Xbox systems.   Parents of kids who hope to play their new Christmas presents on Sunday might want to brace themselves for some tears.

Cyber criminals compromising virtual machines in cloud to increase scale of DDoS

The recently released Microsoft’s latest Security Intelligence Report states that cyber-criminals are compromising virtual machines in the cloud as a way to vastly increase the scale of Distributed Denial of Service Attacks (DDoS). Microsoft has warned of many new cyber risks faced by IT companies in the report. It says that hackers have learned how to use compromised virtual machines running in the cloud to launch massive cyber-attacks. The report says: “In the cloud weaponisation threat scenario, an attacker establishes a foothold within a cloud infrastructure by compromising and taking control of a few virtual machines. The attacker can then use these virtual machines to attack, compromise, and control thousands of virtual machines—some within the same public cloud service provider as the initial attack, and others inside other public cloud service providers.” Attackers can easily issue commands to launch DDoS attacks that cripple online services and websites or flood the internet with spam. Microsoft’s cloud computing platform, Azure, has witnessed attempts to exploit the cloud to establish communications with malicious IP addresses and brute force RDP, the Remote Desktop Protocol used by Microsoft to allow users to access their desktops over a network, representing 41% and 25.5% of all outbound attacks, respectively. Spam followed at just over 20% and DDoS attempts made up 7.6% of attacks. The company is also warning IT administrators to be on the lookout for targeted threats aimed at taking control of an email account that has a high probability of containing credentials that can be used to gain access to the public cloud administrator portal. If successful, the threats may open both their on-premises and cloud infrastructures to attack. The attacker, after logging into the administrator portal, can gather information and make changes to gain access to other cloud-based resources, execute ransomware, or even pivot back to the on-premises environment. They are also keeping tabs on GitHub and other public code repositories, hoping that developers will accidentally publish secret keys that can potentially grant access to cloud accounts and services. Microsoft has further warned of “Man in the Cloud” (MitC) attacks wherein victims are tricked into downloading and installing malware, typically with an email containing a malicious link. Once active, the malware searches for a cloud storage folder and replaces the victim’s synchronisation token with that of the attacker’s. After this, whenever a user adds a file to their cloud storage accounts each time, a copy is delivered to the attacker. http://www.cloudcomputing-news.net/news/2016/dec/16/cyber-criminals-compromising-virtual-machines-cloud-increase-scale-ddos/ http://www.eweek.com/security/microsoft-report-says-hackers-weaponizing-cloud-virtual-machines.html Source: https://www.ddosattacks.net/wp-admin/post-new.php
