What retailers need to know about cybersecurity

Annual global costs tied to destruction of data, intellectual property theft, lost productivity and fraud are on pace to reach $6 trillion by 2021. Here’s how retailers can avoid becoming a statistic. Cybercrime is big business — and retailers are squarely in the crosshairs. Cybercrime — the catch-all term applied to an ever-expanding range of digital assaults from malware to theft of personal data to distributed denial-of-service attacks (DDoS, i.e. coordinated traffic onslaughts on servers, systems or networks designed to make the target difficult or impossible for legitimate users to access) — is rapidly growing more common, more dangerous and more complex. Service interruptions from DDoS attacks alone surged 162% in 2016. Cybercrime is also growing more lucrative: Nearly 90% of all cyberattacks now involve financial or espionage motivations, according to the Verizon 2016 Data Breach Investigations Report. Corresponding annual global costs related to damage and destruction of data, intellectual property theft, lost productivity and fraud are on pace to grow from $3 trillion in 2015 to $6 trillion by 2021. While the second half of 2016 brought to light three of the largest data breaches ever recorded (two raids on web platform Yahoo that impacted at least 1.5 billion accounts combined; the other affecting about 412 million accounts across social network Adult Friend Finder), retailers in fact experience the most cyberattacks of any industry sector — about three times as many as the previous top target, the financial industry — information and communications technology firm NPD Group reports. The list of victims is long and ignominious, and includes Target, Home Depot, Eddie Bauer and Vera Bradley. The question isn’t if and when yet another retailer will fall victim in the weeks and months ahead, experts say, but simply where the wheel of misfortune will land next. “You’ll never be able to put up perimeters and defenses to stop the behavior of malicious attackers. Organizations need to accept the fact that if they’re not breached today, they likely will be breached at some point in the point in the future,” Paul Truitt, vice president of cybersecurity services at managed network solutions firm SageNet, told Retail Dive. “Getting ahead of the criminal and stopping them before they do what they’re going to do is a losing battle. But acting quickly and having the processes in place to respond what it does happen is achievable, and if every organization had that in place, we could significantly shorten the average data breach notification and identification, and also create much less juicy targets for the bad guys.” Threat assessment Retailers are like catnip to cybercriminals because of the wealth of customer data stored on their networks. While hijacking credit card account data has long been the primary objective — about 42 million Target shoppers had their credit or debit information stolen when the retailer was breached in late 2013 — thieves are also keen to acquire personal data like names, mailing addresses, phone numbers and email addresses. “There’s a lot of data around shopping habits and purchasing patterns now being stored by retailers — information they never had before,” Truitt said. “If you’re tying a loyalty program to a mobile payment program, those payment programs are bringing more sensitive data into the retail organization than in the past, and that’s what criminals are looking for.” The threat isn’t lost on retailers. Fully 100% of retail executives surveyed for the 2016 BDO Retail RiskFactor Report cited data privacy and security breaches as major business risks, up from 55% in 2011 and 26% in 2007. But according to Truitt, relatively few retailers have advanced their cybersecurity efforts beyond implementing the basic safeguards necessary to meet payment card industry (PCI) security standards. “[Cybersecurity] varies by retailer,” he said. “We still see a lot of retail organizations putting their eggs into the PCI basket. The feeling is that they’ve secured their organizations by meeting PCI compliance requirements, but in reality, the vectors of attack are outside what PCI mandates needs to be done. When you think about security programs focusing only on PCI at best, we’re going to see a lot of data continue to be exposed.” The media fallout and brand damage associated with past merchant data breaches (not to mention the legal costs and governmental penalties, which can run into the millions) are driving retailer cybersecurity awareness and investment, says Robert Horn, associate director at insurance and risk management solutions provider Crystal & Co. “Retailers have been forced to increase their cybersecurity because of the breaches we’ve had in the last several years. Your public perception takes a hit, there’s customer churn, and the fines and penalties are increasing,” Horn told Retail Dive. “Cybersecurity is getting much more attention from the C-suite. Before, just the IT director was involved. Now you’ve got legal, you’ve got corporate governance, you’ve got the CFOs and the CEOs wanting to know what’s going on.” But knowing what’s going on is easier said than done, because cybercrime evolves with mind-boggling speed. What began two decades ago with relatively simple viruses and website attacks hatched by malcontents seeking internet notoriety has rapidly mutated into discrete, laser-targeted and highly sophisticated offensives masterminded by thieves, hackers and extortionists motivated by financial gain. “There isn’t a single organization that can say they’re 100% secure,” Maarten Van Horenbeeck, vice president of security engineering at content delivery network Fastly, told Retail Dive. “But there are organizations that have the maturity and the smart people to say, ‘We understand what is happening, and we believe we know how to defend against it and how to protect our customer data.’” Personnel and protection Understanding what’s happening begins with identifying potential cracks in your armor. Verizon found that most attacks exploit known vulnerabilities that businesses failed to patch, despite software providers making patches available months or even years prior to the breach taking place. In fact, the top 10 known vulnerabilities account for about 85% of all successful exploits each year. Avoiding disaster also depends on recognizing the warning signs and criminal patterns: 95% of breaches and 86% of security incidents fall into nine established exploit patterns. Building a more secure retail business begins with smart personnel decisions. “The single biggest thing an organization can do today is hire the right people. There are so many technologies out there,” Van Horenbeeck said. “It’s like putting together a puzzle of the correct pieces to make sure you’re defending yourself against attack. You need to hire the right people who understand that puzzle, and who know how to make the organization as safe as possible.” Perhaps no retail security solution has generated more headlines and discussion than the fall 2015 shift from traditional “swipe-and-signature” credit and debit cards to chip-enabled EMV cards, a move designed in part to better protect consumers from escalating transaction fraud. While EMV (which takes its name from Europay, MasterCard and Visa, the three companies that created its chip-integrated standard) effectively blocks card cloning and other commonplace criminal tactics, its security innovations are limited to transactions where the physical card is present, meaning many cyberthieves are shifting their focus from brick-and-mortar stores to the web. That means retailers dependent on e-commerce must embrace software solutions including end-to-end software encryption, a method of secure communication that prevents hackers, internet service providers or any other third party from accessing, stealing or damaging cardholder data or other information during its transfer from one system or device to another. “Organizations that have made investments in EMV but did not invest in end-to-end encryption have a risk misperception,” said SageNet’s Truitt. “They believe they are secure, but they’ve only accomplished authentication of credit cards. They’ve accomplished nothing related to the security of the actual transaction. Many retailers that don’t have security teams internally, or that outsource their security fully and don’t have anyone with that knowledge in-house, has misinformed themselves about what EMV is doing. We’re going to see more organizations put fewer security controls in place and reduce some spend, because they think they have put the right security in place. But they’ve left themselves more exposed than they used to be.” Beyond the basics, retailers should also consider adopting data loss prevention solutions to help monitor, manage and protect confidential data wherever it’s stored or used, as well as emerging tools like advanced behavioral authentication (methodologies that monitor headquarters and store employees’ attributes and behaviors to prevent imposters from accessing infrastructure and data), data-mining and visualization techniques, and security response automation. There’s no time to waste. Experts anticipate cybercrime to continue to increase in the months to come, and warn that emerging technologies like the Internet of Things and advances in artificial intelligence present a multitude of new opportunities for attack. Only the strong will survive. “It’s hard to predict what new threats will come about,” said Horn. “[Security] all comes down to putting resources into cybersecurity teams. A bad breach can put you out of business.” Source: http://www.retaildive.com/news/what-retailers-need-to-know-about-cybersecurity/435567/

The next generation of cyber attacks — PDoS, TDoS, and others

2016 was a landmark year in cyber security. The cyber landscape was rocked as Internet of Things (IoT) threats became a reality and unleashed the first 1TB DDoS attacks — the largest in history. Security experts had long warned of the potential of IoT attacks, and a number of other predictions also came true; Advanced Persistent Denial of Service (APDoS) attacks became standard, ransom attacks continued to grow and evolve and data protection agreements dominated privacy debates. So what’s coming in 2017? Well, for years there have been theories about how a cyber attack could cripple society in some way. So what would this look like, and how could it come to fruition in 2017? An attack type that has been largely ignored that could prove to be key in a major cyber attack is the Permanent Denial of Service (PDoS) attack. This attack type is unique as rather than collecting data or providing some on-going nefarious function its only aim is to completely prevent its target’s device from functioning. PDoS, or Phlashing PDoS, also known as “phlashing”, often damages its target to such an extent that replacement or reinstallation of hardware is usually required. Although the attack type itself has been around for some time now, but it’s easy to imagine how much damage they could do it today’s connected world, and therefore it could quickly gain momentum in 2017. For example, one method PDoS leverages to accomplish its damage is remote or physical administration on the management interface of the victim’s hardware, such as routers, printers, or other networking hardware. In the case of firmware attacks, the attacker may use vulnerabilities to replace a device’s basic software with a modified, corrupt, or defective firmware image. This “bricks” the device, rendering it unusable for its original purpose until it can be repaired or replaced. Other attacks include overloading the battery or power systems. We’ve already seen the potential harm that a PDoS attack could cause, when in November last year an attack on residential apartments in Finland targeted the building management system. The attack took the system offline by blocking its Internet connection, causing it to keep rebooting itself in order to reconnect. As a result, the system was unable to supply heating at a time when temperatures were below freezing. Fortunately, the facilities service company were able to relocate residents while the system was brought back online. You only have to consider devices like Samsung’s Note 7 to see the safety hazards that the devices we all carry around with us can potentially harbor. There have been numerous test cases of malware and bots overheating devices, causing them to physically distort or worse. These attacks, bundled into a cyber attack, could have devastating and lasting effects beyond what we commonly think about in the world of the “nuisance” DDoS attack. Another attack type that has flown under the radar is Telephony Denial of Service (TDoS). This attack type will likely rise in sophistication and become a key tool in cyber attackers’ arsenals, particularly those who are more interested in wreaking havoc than having financial gain as a motivator. The rise of the Darknet Just imagine an attacker with the ability to cut off communications during a crisis period. This would hinder first responders, exacerbate suffering and in some situations it could potentially increase loss of life. A physical attack, such as a terror attack, followed by a targeted TDoS attack on communication systems could be devastating. Like PDoS, TDoS has been around for some time but again, as we depend more and more on these connected systems the impact of a targeted attack becomes magnified. One prediction that has come true in the past few years is the rise of the Darknet. However, in 2017 it could go a step further and become a mainstream tool that almost anyone can use to launch attacks or manipulate data. The Darknet offers easy and affordable access to attacks that can terrorize or otherwise alter someone’s personal details for financial or other benefits. The scope of the Darknet is also reaching further than ever thanks to the huge increase in connected devices that the general public has at their disposal. Examples include the ability to rent compromised surveillance systems, access to legal information including lawyers’ emails and the ability to view and manipulate medical or educational records. 2017 could see a frightening scenario develop where the definitive source of who we are and how our details are recorded and accessed is unknown. Just imagine being in a job interview and your CV doesn’t match your online school records. Who will the potential employer trust? This analogy can be extended to numerous scenarios, but the common thread is that your online records require high security and fidelity in order for you to function properly in society. In light of that, one of the single most personalized acts of terror that can occur is a wide-scale loss, alteration or deletion of records — with no reconstitution capability. This should strike fear in us all. Source: https://betanews.com/2017/02/09/the-next-generation-of-cyber-attacks-pdos-tdos-and-others/

Everything old is new again: Experts predict a flood of denial-of-service attacks

As IoT goes mainstream Mirai-style denial-of-service botnet attacks are escalating, and hackers are targeting health care companies, financial services, and the government. The hottest trend in cyberattacks is an archaic and simplistic hacker tool. Propelled by the rise of IoT, the popularity of denial-of-service attacks rebounded in late 2016 and early 2017. Accompanying the rapid acceleration of the IoT and connected device market, warn cybersecurity experts, will be a zombie botnet swarm of network-crippling attacks. Denial-of-service attacks are simple but effective weapons that bring down websites and services by flooding networks with junk traffic from commandeered botnets. Digital fallout will often cripple the target and ripple across the web to knock out unaffiliated but connected services and sites. “After an attack [clients] often feel angry and violated,” said Matthew Prince, CEO of denial-of-service mitigation service CloudFlare in an interview with TechRepublic. “A distributed denial-of-service (DDoS) attack is not a sophisticated attack. It’s the functional equivalent of a caveman with a club. But a caveman with a club can do a lot of damage.” “DDoS outages are causing companies to completely rethink their cybersecurity strategies,” said cyber-defence strategist Terrence Gareau in a report by threat identification firm Nexusguard. Nexusguard examines network data to identify threat vector trends like duration, source, and variation of denial-of-service attacks.”Hackers’ preferences for botnets over reflection attacks are typical of cyclical behavior, where attackers will switch to methods that have fallen out of popularity to test security teams with unexpected vectors.” Denial-of-service attacks are a broad umbrella used to describe a number of technological sub-tactics. Denial-of-service attacks are common and relatively easy to pull off because these attacks simply crowdsource web IP addresses. The hacker group Anonymous made DDoS attacks famous by championing a tool nicknamed the “Low Orbit Ion Cannon” that made denial-of-service accessible and easy. The downside, of course, is that all cyberattacks are illegal, and unsophisticated DDoS attacks are easy for law enforcement to pursue. The Nexusguard report shows that hackers are switching from DDoS to IoT botnet-based attacks like last year’s devastating Mirai hack. “Distributed denial-of-service attacks fell more than 40 percent to 97,700 attacks in the second quarter of the year,” Gareau said. IoT attacks targeted at French data provider OVH broke records for speed and size, the report said, and were so severe that France broke into Nexusguard’s Top 3 [cyberattack] victim countries. “The preferred programming language for the Mirai botnet helped to better handle a massive number of nodes compared to other typical languages for DDoS attacks,” Gareau said. “Researchers attribute the [DDoS] attack dip and these massive attacks to hackers favoring Mirai-style botnets of hijacked connected devices, demonstrating the power IoT has to threaten major organizations.” Hackers are also diversifying attacks against large organizations in financial services, healthcare, and government sectors, Gareau said in the Nexusguard report. “Hackers favored blended attacks, which target four or more vectors, in attempts to overload targeted monitoring, detection, and logging systems.” To fend off attacks, experts like Prince, Gareau, and Cyberbit’s chief technology officer Oren Aspir agree enterprise companies need to develop a response plan. “Attacks on an endpoint device will always leave some sort of trail or evidence to analyze,” Aspir said. “Since the speed of detection is vital, analysts need tools that will allow them to quickly detect behavior at the endpoint, validate the threat, and perform an automated forensic investigation in real time on that endpoint.” Aspir also suggested companies prepare for DDoS and other hacks by reviewing previous attack metrics, conduct vulnerability assessment and penetration testing exercises, and simulate attacks to help evaluate team preparedness. “It’s important for organizations to build a baseline that consists of what ‘good behavior’ should look like on an endpoint. This allows for organizations to take unknown threats and validate them quickly.” Though IoT botnet denial-of-service attacks are relatively new enterprise organizations have learned from previous attacks and already shifted defense tactics. “Researchers predict the attention from recent botnet attacks will cause companies to strengthen their cybersecurity… and ensure business continuity despite supersized attacks,” Gareau said.

DDoS Attack Takes Down Austrian Parliament Website

The DDoS attack, one of the most common cyber threats, is being investigated by authorities The Austrian parliament’s website was hit by a suspected cyber attack over the weekend which took the site down for 20 minutes. Hackers are believed to have used a Distributed Denial of Service (DDoS) attack to flood the website with digital service requests and, although no data was lost, authorities are now investigating the attack. “The hacker attack was most likely a so-called DDoS-attack; a similar attack took place last November targeting the websites of the Foreign Affairs and Defence Ministries,” the parliament said in a statement. Cyber attack One of the most common cyber threats around, DDoS attacks have been growing in size and prevalence in recent times, with Corero Network Security predicting that such threats will become the top security priority for businesses and the new norm in 2017. “While the Mirai botnet is certainly fearsome in terms of its size, its capacity to wreak havoc is also dictated by the various attack vectors it employs, said Dave Larson, CTO/COO at Corero Network Security. “If a variety of new and complex techniques were added to its arsenal next year, we may see a substantial escalation in the already dangerous DDoS landscape, with the potential for frequent, Terabit-scale DDoS events which significantly disrupt our Internet availability.” In January, a DDoS attack was responsible for an outage at Lloyds Banking Group that left customers unable to access online banking services for three days, after web security firm Imperva had earlier that month issued a warning to businesses after fending off the largest DDoS attack ever recorded on its network. But the most high-profile attack in recent months affected domain name service provider Dyn and resulted in a slew major sites – including Twitter, Spotify and Reddit – being taken offline.

DDoS attack on Dyn costly for company: claim

A distributed denial of service attack on Dynamic Network Services, otherwise known as Dyn, in October 2016, led to the company losing a considerable amount of business, according to data from the security services company BitSight. A report at the Security Ledger website said while Internet users endured short-term pain because they were cut off from popular websites during the attack, the company, Dyn, lost the business of about 8% of the domains — about 14,500 — it was hosting shortly thereafter. This figure was based on statistics in a talk given on 24 January by Dan Dahlberg, a research scientist at BitSight Technologies in Cambridge, Massachusetts. Dyn is based in Manchester, New Hampshire. It was recently bought by Oracle Corporation. During the outage, Dyn was targeted by hackers who are said to have used digital video recorders and security cameras which were compromised by malware known as Mirai and used to form a massive botnet. The first attack, on 21 October 2016 US time, began at 7.10am EDT (10.10pm AEDT) and, once this was resolved by Dyn, further waves caused disruptions throughout the day. While major US websites like Twitter, Spotify, Netflix and Paypal were disrupted, the application performance management software company Dynatrace said that Australian websites were affected as well. Among the Australian sites that took a hit, Dynatrace listed AAMI, ANZ, BankWest, Coles, The Daily Telegraph, Dan Murphy’s, ebay, HSBC, The Herald Sun, NAB, 9News, The Age, Ticketmaster, The Australian, Woolworths, The Sydney Morning Herald, and Westpac. BitSight provides security rating services for companies. It analysed 178,000 domains that were hosted on Dyn’s managed DNS infrastructure before and after the attacks; of these 145,000 used Dyn exclusively, while the remaining 33,000 used Dyn and others too. After the attack, according to Dahlberg, 139,000 of the 145,000 domains managed exclusively by Dyn continued to use its services, a loss of 4% or 6000 domains. Among domains that used Dyn and other providers as well, there was a loss of 8000 domains, or 24%. Security Ledger said it had tried to get a comment from Dyn but was refused one. It is not clear whether any of the 14,500 domains that were found not to be using Dyn’s services in the aftermath of the attack returned to the provider.

SQL Sequel: Sequel Slammer worm resurfaces after more than a decade

SQL Slammer, a fast-moving worm that generated a wave of distributed denial of service (DDoS) attacks in 2013, mysteriously resumed high levels of activity in late 2016 after more than a decade of dormancy. According to a company blog post Thursday, Check Point Software Technologies detected a “massive” surge in SQL Slammer attacks between Nov. 28 and Dec. 4, 2016. “What we’ve been seeing is not the actual worm, but its attempts to reach more servers,” said Maya Horowitz, group manager, threat Intelligence at Check Point, in an email interview with SC Media. “Therefore we cannot know for sure if any changes have been [made to] the worm or the vulnerabilities it exploits.” When it first surfaced in 2003, the worm managed to infect tens of thousands of servers and routers in a matter of minutes by exploiting a buffer overflow vulnerability (CVE-2002-0649) in Microsoft SQL Server 2000 or Microsoft SQL Server Data Engine 2000 – both of which are no longer supported. These infected, exploited machines would then bombard ransom IP addresses with an enormous stream of malicious packets that would infect other vulnerable systems, while simultaneously overloading Internet-based network devices with traffic. Microsoft patched this vulnerability in Jan. 2003 and over the years has issued multiple new versions of the affected products. This makes these latest attacks ever stranger, because unless the worm has evolved in some way, it is hard to imagine that users remain susceptible to this threat. “One theory to why it’s attempting to make a comeback is that cybercriminals are seeking easy ways to cause DoS and slow down the entire Internet, just like with the recent Mirai botnet,” said Horowitz. “And reusing old malware is the easiest way.” Source:https://www.scmagazine.com/sql-sequel-sequel-slammer-worm-resurfaces-after-more-than-a-decade/article/636156/

39% of businesses not ready to protect themselves against DDoS

Companies are not ready to protect themselves against DDoS, with four in ten (39%) businesses unclear about the most effective protection strategy to combat this type of attack, according to research from Kaspersky Lab. A lack of knowledge and protection is putting businesses at risk of grinding to a halt. DDoS attacks can quickly incapacitate a targeted business’s workflow, bringing business-critical processes to a stop. However, the research found that nearly a fifth (16%) of businesses are not protected from DDoS attacks at all, and half (49%) rely on built-in hardware for protection. This is not effective against the increasing number of large-scale attacks and ‘smart’ DDoS attacks which are hard to filter with standard methods. Large-scale cyberattacks are now commonplace, such as the recent attack on telecommunications provider StarHub, which faced a high-profile DDoS attack in October last year. Hackers are also showing a preference for DDoS attacks, with the proliferation of IoT devices today. As IoT devices have weak security protocols, they are easy targets for hackers to launch DDoS attacks from. As IoT devices are forecasted to hit 21 billion in 2020, each potential entry point into an organisation increases vulnerability to DDoS attacks. Many businesses are in fact aware that DDoS is a threat to them – of those that have anti-DDoS protection in place, a third (33%) said this was because risk assessments had identified DDoS as a potential problem, and one in five (18%) said they have been attacked in the past. For some, compliance, rather than awareness of the security threat, is the main driver, with almost half (43%) saying regulation is the reason they protect themselves. The problem for businesses is that, in many cases, they may assume they’re already protected. Almost half (40%) of the organizations surveyed fail to put measures in place because they think their Internet service provider will provide protection, and one in three (30%) think data center or infrastructure partners will protect them. This is also not always effective, because these organizations mostly protect businesses from large-scale or standard attacks, while ‘smart’ attacks, such as those using encryption or imitating user behavior, require an expert approach. Moreover, the survey found that a third (30%) fail to take action because they think they are unlikely to be targeted by DDoS attacks. Surprisingly, one in ten (12%) even admit to thinking that a small amount of downtime due to DDoS would not cause a major issue for the company. The reality is that any company can be targeted because such attacks are easy for cybercriminals to launch. What’s more, the potential cost to a victim can reach 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.” Source: http://www.networksasia.net/article/39-businesses-not-ready-protect-themselves-against-ddos.1486046674

The emergence of new global cybercriminal attack patterns

The findings of a new Malwarebytes report illustrate a significant shift in cybercriminal attack and malware methodology from previous years. Ransomware, ad fraud and botnets, the subject of so much unjustified hype over previous years, surged to measurable prominence in 2016 and evolved immensely. Cybercriminals migrated to these methodologies en masse, impacting nearly anyone and everyone. To better understand just how drastically the threat landscape evolved in 2016, researchers examined data taken from Windows and … More ?

Assessing The Massive Security Vulnerability Of The Internet Of Things

The increase in connected devices could make 2017 a banner year for cyber attacks. A report by global professional services company Deloitte said that Distributed Denial of Service (DDoS) attacks will grow in size and scale in 2017, thanks in part to the growing multiverse of connected things. According to Deloitte’s annual Technology, Media and Telecommunications Predictionsreport, DDoS attacks will be more frequent, with an estimated 10 million attacks in total over the next 12 months. DDoS attacks are no new phenomena. The potential impact on an organization from this category of cyber threat should never be underestimated, Deloitte said. The report said that the size of DDoS attacks has increased year-on-year. Between 2013 and 2015, the largest attacks did not exceed 500 gigabits per second. In 2016, there were two attacks that exceeded one terabit per second. Over the next 12 months, the average attack size is forecast to be between 1.25- and 1.5 GBs per second, with at least one per month exceeding 1 TB per second. On a basic level, the success of DDoS attack is focused on making a website or network resource—a server, for example—unusable. This scenario is achieved by creating a flood of Internet traffic from multiple sources that are launched simultaneously. The website or resource is then overwhelmed, resulting in a suspension of service or access. For example, an ecommerce website that is hit by a DDoS attack would be unable to sell its products until the attack was contained. At the same time, any exposed vulnerabilities could produce a knock-on effect and take other organizations or websites down with it. “DDoS attacks are the equivalent of hundreds of thousands of fake customers converging on a traditional shop at the same time,” the report said. “The shop quickly becomes overwhelmed. The genuine customers cannot get in and the shop is unable to trade as it cannot serve them.” Connected Devices Are An Easy Target There are several methods for creating this type of chaos but the most common are botnets and amplification attacks. A DDoS attack generated through a botnet accesses hundreds of thousands of connected devices that have been told to act in disruptive manner via malicious code. An amplification attack also uses malicious code by instructing a server to generate multiple fake IP addresses that are then sent to a website—known as “spoofing”—which then overwhelm that service. Both of these approaches are widely known, although it is the botnet that has become more prevalent. Irrespective of how widespread the impact is on an organization or network, Deloitte said that three concurrent trends will escalate the potential for DDoS attacks in 2017—the Internet of Things, widely available malware and high bandwidth speeds. The prime culprit will be the Internet of Things. Connected devices are notoriously insecure and ripe for being taken over by a third party. The standard way to gain remote access to a device is through a user ID or password, but some people may not be aware that a device’s firmware offers hackers a way in, Deloitte said. Deloitte said: The majority of users are familiar with the need to change user ID and passwords before using a device for the first time, and at regular intervals thereafter. But approximately half a million of the billions of IoT devices worldwide—a small proportion of the total, but a relatively large absolute number—reportedly have hard-coded, unchangeable user IDs and passwords. In other words, they cannot be changed, even if the user wants to. Hard-coded user IDs and passwords are not an issue provided that a third party doesn’t know what they are. The problem is that they can be easy to find. The Internet Of Things Is Always Exploitable Anyone with a degree of programming knowledge can sift through a device’s firmware to discover what these IDs and passwords are, the report said. In addition, a compromised Internet of Things device may not show any signs of being compromised to its owner, especially if there is no obvious deterioration in performance. Theoretically, millions of devices could be affected without their owners having any idea that the device was part of a botnet, Deloitte said. Consumer confidence in the Internet of Things is aligned with how secure a connected device is, confidence that can be shattered if that device can be exploited with little effort. For example, the cyber attack on October 21, 2016, that affected the Dyn network was attributed to a botnet that used Internet-connected devices to take down numerous high-profile services that included Twitter, Amazon.com, Spotify, Comcast, Fox News and PayPal. Thousands of connected devices were used in this attack, which is now accepted as one of the largest of its kind to date. Any company or organization that has a presence on the Internet should be aware that DDoS attacks are not going to stop anytime soon. The report cited several sectors that should be alert to the impact that a successful DDoS attack could have including (but not limited to) retailers with a high proportion of online revenue, video streaming services, financial or professional service companies and online video games providers. “Some organizations may have become a little blasé about DDoS attacks, however these attacks are likely to increase in intensity in 2017 and beyond, and the attackers are likely to become more inventive,” said Deloitte. “Unfortunately, it may never be possible to relax about DDoS attacks. The DDoS genie is out of the bottle, and is unlikely to pop back in.” Source: https://arc.applause.com/2017/01/27/ddos-iot-vulnerability-asssessment/
