Ransomware isn’t the only cyberthreat your business will face this year. Here are five emerging threats that leaders need to know about.
The cyberthreat landscape continues to evolve, with new threats emerging almost daily. The ability to track and prepare to face these threats can help security and risk management leaders improve their organization’s resilience and better support business goals.
The number of high-profile breaches and attacks making headlines has led business leaders to finally take cybersecurity seriously, said Sam Olyaei, senior principal and analyst at Gartner.
“Today, not only are business leaders and the business community understanding cybersecurity, they know it’s important to their business outcomes and objectives,” Olyaei said. “The problem is, there is still a lack of understanding as to why it’s important.”
Firms must work to bridge the gap between communicating the technical aspects of cybersecurity and the business outcomes, such as customer satisfaction, financial health, and reputation, Olyaei said.
Keeping track of new threats and not just established ones like ransomware is key for a strong security posture, said Josh Zelonis, senior analyst at Forrester.
“Whenever we develop our strategies for how we’re going to protect our organizations, it’s really easy to look at things that you’re familiar with, or that you have a good understanding of,” Zelonis said. “But if you’re not looking ahead, you’re building for the problems that already exist, and not setting yourself up for long-term success. And that is really the number one reason why you need to be looking ahead — to understand how attack techniques are evolving.”Bringing the Power of Lithium-Ion for IoT and Edge Computing Applications through APC Smart-UPSLi-Ion battery technology offers a host of benefits that make it an attractive and affordable option for a growing set of businesses reliant on distributed IT infrastructure.Sponsored by Schneider Electric
Here are five emerging cybersecurity threats that business, technology, and security leaders need to take seriously this year.
1. Cryptojacking
Ransomware has been one of the biggest threats impacting businesses in the past two years, exploiting basic vulnerabilities including lack of network segmentation and backups, Gartner’s Olyaei said.
Today, threat actors are employing the same variants of ransomware previously used to encrypt data to ransom an organization’s resources or systems to mine for cryptocurrency — a practice known as cryptojacking or cryptomining.
“These are strains of malware that are very similar to strains that different types of ransomware, like Petya and NotPetya, had in place, but instead it’s kind of running in the background silently mining for cryptocurrency,” Olyaei said.
The rise of cryptojacking means the argument that many SMB leaders used in the past — that their business was too small to be attacked — goes out the window, Olyaei said. “You still have computers, you still have resources, you still have applications,” he added. “And these application systems, computers, and resources can be used to mine for cryptocurrency. That’s one of the biggest threats that we see from that standpoint.”
2. Internet of Things (IoT) device threats
Companies are adding more and more devices to their infrastructures, said Forrester’s Zelonis. “Organizations are going and adding solutions like security cameras and smart container ships, and a lot of these devices don’t have how you’re going to manage them factored into the design of the products.”
Maintenance is often the last consideration when it comes to IoT, Zelonis said. Organizations that want to stay safe should require that all IoT devices be manageable and implement a process for updating them.
3. Geopolitical risks
More organizations are starting to consider where their products are based or implemented and where their data is stored, in terms of cybersecurity risks and regulations, Olyaei said.
“When you have regulations like GDPR and threat actors that emerge from nation states like Russia, China, North Korea, and Iran, more and more organizations are beginning to evaluate the intricacies of the security controls of their vendors and their suppliers,” Olyaei said. “They’re looking at geopolitical risk as a cyber risk, whereas in the past geopolitical was sort of a separate risk function, belonging in enterprise risk.”
If organizations do not consider location and geopolitical risk, those that store data in a third party or a nation state that is very sensitive will run the risk of threat actors or nation state resources being used against them, Olyaei said. “If you do that then you also impact the business outcome.”
4. Cross-site scripting
Organizations struggle to avoid cross-site scripting (XSS) attacks in the development cycle, Zelonis said. More than 21 percent of vulnerabilities identified by bug bounty programs are XSS areas, making them the leading vulnerability type, Forrester research found.
XSS attacks allow adversaries to use business websites to execute untrusted code in a victim’s browser, making it easy for a criminal to interact with a user and steal their cookie information used for authentication to hijack the site without any credentials, Forrester said.
Security teams often discount the severity of this attack, Zelonis said. But bug bounty programs can help identify XSS attacks and other weaknesses in your systems, he added.
5. Mobile malware
Mobile devices are increasingly a top attack target — a trend rooted in poor vulnerability management, according to Forrester. But the analyst firm said many organizations that try to deploy mobile device management (MDM) solutions find that privacy concerns limit adoption.
The biggest pain point in this space is the Android installed base, Zelonis said. “The Google developer site shows that the vast majority of Android devices in the world are running pretty old versions of Android,” he said. “And when you look at the motivations of a lot of IoT device manufacturers, it’s challenging to get them to continue to support devices and get timely patches, because then you’re getting back to mobile issues.”
Organizations should ensure employee access to an anti-malware solution, Forrester recommended. Even if it’s not managed by the organization, this will alleviate some security concerns.

Cybercrime, DDoS, IoT – what should you pay attention to next year?
1. Increase in crime, espionage and sabotage by rogue nation-states
With the ongoing failure of significant national, international or UN level response and repercussion, nation-state sponsored espionage, cyber-crime and sabotage will continue to expand. Clearly, most organisations are simply not structured to defend against such attacks, which will succeed in penetrating defences. Cybersecurity teams will need to rely on breach detection techniques.
2. GDPR – The pain still to come
The 25th of May, 2018 has come and gone, with many organizations breathing a sigh of relief that it was fairly painless. They’ve put security processes in progress and can say that they are en route to a secure situation – so everything is OK?
We are still awaiting the first big GDPR penalty. When it arrives, organizations are suddenly going to start looking seriously at what they really need to do. Facebook, BA, Cathay Pacific, etc. have suffered breaches recently, and will have different levels of corporate cost as a result, depending on which side of the May 25th deadline they sit. So GDPR will still have a big impact in 2019
3. Cloud insecurity – it’s your head on the block
Cloud insecurity grew in 2018 and, unfortunately, it will carry on growing even more in 2019. Increasing amounts of data are being deployed from disparate parts of organizations, with more and more of that data ending up unsecured.
Despite the continual publicity around repeated breaches, the majority of organizations do not have good housekeeping deployed and enforced across their whole data estate in the cloud. To give an idea of the scale, Skyhigh Networks research indicated that 7 percent of S3 buckets are publicly accessible and 35 percent are unencrypted.
4. Single factor password – the dark ages
As if we need the repetition, single-factor passwords are one of the simplest possible keys to the kingdom (helped by failure to manage network privileges once breached). Simple passwords are the key tool for attack vectors, from novice hackers right the way up to nation-state players. And yet they still remain the go-to security protection for the majority of organizations, despite the low cost and ease of deployment of multi-factor authentication solutions. Sadly, password theft and password-based breaches will persist as a daily occurrence in 2019.
5. Malware – protect or fail
Ransomware, crypto mining, banking Trojans and VPN filters are some of the key malware challenges that continue to threaten businesses and consumers. Live monitoring by Malwarebytes, Kaspersky and others, has shown that the mix of threats varies during the year, but the end result of malware threats will be a bad 2019.
Increasing sophistication will be seen in some areas such as ransomware, alongside new malware approaches and increased volumes of malware in other areas. Traditional AV will not provide sufficient protection. Solutions that have a direct malware focus are essential for organizations, alongside tracking of network activity (in and out of the network). With Cybersecurity Ventures predicting that ransomware damage costs will exceed $11.5 billion by 2019, it certainly won’t be going away. Oh yes, and make sure that your backup plan is working and tested.
6. Shift in attack vectors will drive cyber hygiene growth
The ongoing shift of attack vectors, from the network to the user, is causing a reappraisal of how to manage security. Driven partly by the shift in boardroom awareness, and partly by GDPR, many organizations are recognizing, perhaps belatedly, that their users are their weakest link.
Not only is there a greater awareness of the insider threat from malicious current and ex-staff, but there is also a growing recognition that staff cyber awareness and training is a crucial step in securing this vulnerable area. The response from organzations will take the form of cyber education, coupled with testing, measuring, and monitoring staff cyber behavior. Increasingly, Entity and User Behaviour Analytics (EUBA) systems will be adopted, alongside training programs and automated testing, such as simulated phishing and social engineering attacks.
7. IoT – the challenge will only increase
We’ve already seen some of the security challenges raised by IoT, but 2019 will significantly demonstrate the upward trend in this area. Driven by the convenience and benefits that IoT can deliver, the technology is being increasingly deployed by many organizations, with minimal thought by many as to the security risks and potential consequences.
Because some IoT deployments are well away from the main network areas, they have slipped in under the radar. In the absence of a standard, or indeed a perceived need for security, IoT will continue to be deployed, creating insecurity in areas that were previously secure. For the greatest percentage of IoT deployments, it is incredibly difficult or impossible to backfit security. This means that the failure to segment on the network will further exacerbate the challenges IoT will create in 2019 and beyond.
8. Increasing risks with shadow IT systems and bad housekeeping
Shadow IT systems continue to proliferate, as do the number of applications and access points into systems, including legacy applications. In the case of shadow IT systems, these are indefensible as they are; and in the case of increasing applications and access points, if they relate to old or abandoned applications, they are difficult to identify and defend.
In both cases, these are an easy attack surface with significant oversight, internal politics and budget challenges, and were previously seen as a lower priority for resolution. However, there has been both an increased awareness of the opportunity for attack via this route, and an increase in the number of attacks, which will accelerate in 2019.
9. DDoS – usually unseen, but still a nightmare
DDoS is the dirty secret for many organizations and attacks will continue to grow in 2019, alongside the cost of defending against them. Nevertheless, DDoS attacks aren’t generally newsworthy, unless a big name organization is involved, or the site is down for a long time. And, of course, the victim does not want to draw attention to their lack of defence. That’s not good for custom or for share prices.
The cost of launching an attack is comparatively low, often shockingly low, and the rewards are quick – the victim pays for it to go away. Additionally, cryptocurrencies have aided the money transfer in this scenario. Yet the cost for the victim is much higher than the ransom, as it involves system analysis, reconstruction and, naturally, defending against the next attack.
10. Cybersecurity in the boardroom

A decade, perhaps two decades, late for some organisations, cybersecurity is now considered a key business risk by the board. 2019 will see this trend accelerate as boards demand clarity and understanding in an area that was often devolved as a sub-component of the CISO’s role, and was not really a major topic for the boardroom. The financial, reputational and indeed C- Suite employment risks of cyber breach will continue to drive board focus on cybersecurity up the agenda.

As digital transformation takes hold, organizations must learn what their cybersecurity risks are – and how best to address them.
Cybersecurity is in the news, but the risks posed by weak and outdated security measures are hardly new. For more than two decades, organizations have struggled to keep pace with rapidly evolving attack technologies.
With the arrival in May of WannaCry, a massive and highly coordinated ransomware attack that left tens of thousands of organizations around the world hoping for the safe restoration of their data, the threat posed by malware creators took an ominous turn. The attack sent an unambiguous wake-up call to organizations worldwide that now is the time to reassess and reinforce existing cybersecurity strategies.
Connectivity Creates Opportunities and Challenges
Emerging technologies, particularly the Internet of Things (IoT), are taking global connectivity to a new level, opening fresh and compelling opportunities for both adopters and, unfortunately, attackers.
Sadik Al-Abdulla, director of security solutions for CDW, says growing connectivity has ushered in a new era of critical security threats. “The same viruses we’ve been fighting for 20 years, now those viruses grow teeth,” he adds, noting that organizations are just beginning to respond to more dangerous cybersecurity adversaries. “Suddenly, just in the last 18 months, with the explosion of ransomware, we’ve seen really substantial support from outside IT to actually start getting these projects done, because there has been real pain experienced.”
IoT poses a significant new challenge, Al-Abdulla observes. “As new devices are connected, they represent both a potential ingress point for an attacker as well as another set of devices that have to be managed,” he says. “Unfortunately, most of the world is trying to achieve the promise provided by IoT projects as rapidly as possible, and they are not including security in the original design, which creates greater weakness that is very, very hard to get back after the fact and correct.”
Al-Abdulla also notes that many organizations are unintentionally raising their security risk by neglecting routine network security tasks. “Every time our assessment team looks at the inside of a network, we find systems that haven’t been patched in 10 years,” he says. “Sometimes, it’s IoT devices.”
Al-Abdulla’s team has observed devices with “a flavor of Linux or Windows embedded” that have not been updated since they left the factory. Security cameras, badge readers, medical devices, thermostats and a variety of other connected technologies all create potential attack gateways.
“All it takes is the wrong guy to click the wrong thing in the wrong part of the network,” says Martin Roesch, vice president and chief architect of the Cisco Security Business Group. “You get mass propagation throughout the environment, and then you have a huge problem.”
“It’s a very complicated world that we live in right now, because the attacker and defense problem is highly asymmetrical,” Roesch adds.
The changing nature of networks and the devices located within them, combined with the fact that organizations keep introducing new software and hardware into their IT environments, make it nearly impossible to keep pace with a new generation of skilled attackers. “It becomes very, very difficult to respond and be effective against the kind of threat environment that we face today because the attackers are highly motivated,” he says.
The Danger of Giving in to Ransomware
Ransomware is like a thug with a gun: “Pay up, or your data gets it!”
Facing such a blunt demand, many organizations simply cave in and hand over whatever amount of money (usually in the form of bitcoin) is necessary to regain their data.
Problem solved? Not necessarily, says Michael Viscuso, co-founder and chief technology officer of endpoint security provider Carbon Black, who sees no easy way out of a ransomware attack. “It’s still surprising to me that people who have paid the ransom think that the game is over,” he says. “The reality is that the attacker has access to your system and is encrypting and decrypting your files whenever he wants to – and charging you every time.”
James Lyne, global head of security research at security technology company Sophos, notes that many ransomware attackers hide code within decrypted data, allowing them to reinfect the host at a future date. “Because if you’ll pay once, you’ll pay twice,” he explains.
Lyne also warns about the emerging threat of “shredware,” malware that encrypts data without requesting a ransom, effectively destroying it. “I bring that up because I’ve had a lot of board advisory meetings recently where people have said, ‘Well surely, we’ll just keep a fund, and if our data is encrypted, we will just pay the cybercriminals,’” he says.
Instead, organizations can take steps to defend themselves against ransomware. These steps include:
Effective backups: IT staff can save themselves trouble and money by implementing regular backup practices to an external location such as a backup service. In the event of a ransomware infection, backup data can get organizations back on their feet quickly.
User training: Most infections are the result of users clicking on links or attachments that are connected to malicious payloads. IT teams can avoid these pitfalls by training users to look out for them.
Deployment of security solutions: Measures such as anti-malware, firewalls and email filters can help detect ransomware and prevent infections.
The Human Factor
While following security best practices is essential to network security, many organizations remain unaware of or pay little attention to, the weakest link in the security chain: people.
It doesn’t make sense to try to solve what is essentially a human problem solely with technical means, says Mike Waters, director of enterprise information security for management consulting firm Booz Allen Hamilton. “We have to create an atmosphere, an environment, where people can tell us what risks they know about, and we can document them and work through it in a deliberative manner,” he adds.
Booz Allen has 25,000 people working for it, Waters says, adding, “I need 25,000 people to defend Booz Allen.” Educating users — and instilling in them just a touch of paranoia, he quips — leads to an alert organization in which users report every suspicious thing they encounter. “Ninety-nine percent of what they report is not bad, but the 1 percent that’s critical can get to us,” he says. “We reinforce that behavior — tell us everything.”
Meet the Evil Entrepreneurs
In much the same way that organizations boost their results through ambition and innovation, cybercriminals also are improving the way they operate. “The bad guys are entrepreneurial,” says Martin Roesch, vice president and chief architect of the Cisco Security Business Group.
Most successful cybercriminals are part of large and well-structured technology organizations. “There’s a team of people setting up infrastructure and hosting facilities; there’s a team of people doing vulnerability research; there’s a team of people doing extraction of data; there’s a team of people building ransomware; there’s a team of people delivering ransomware; there’s a team of people doing vulnerability assessment on the internet; there’s a team of people figuring out how to bypass spam filters,” says Michael Viscuso, co-founder and CTO of Carbon Black.
Roesch says organizations have found it “very difficult to respond and be effective against the kind of threat environment that we face today,” but says security experts within Cisco have specifically targeted cybercrime organizations and achieved some success in shutting them down.
Weighing Risk Against Benefits
Security boils down to measuring risk against anticipated benefits. “One of the fascinating things about risk is that low-level engineers know where the risks are, but they don’t necessarily tell anybody,” Waters says. As an example, he cites Operation Market Garden, a World War II Allied military effort (documented in the book and movie A Bridge Too Far) that was fatally hampered by poor radio communication. “People knew those radios weren’t going to work when they got over there,” Waters says. “They didn’t tell anybody because they didn’t want to rock the boat.”
Once a risk is identified, users and IT professionals must be committed to addressing it, with the support of executives. Across all departments and in all situations, calm person-to-person communication is always a reliable and effective security tool. “If we’re running around with our hair on fire all the time, they don’t want to talk to us,” Waters adds. “We want everybody to be able to talk with us and share their risks, so we know to prioritize and trust them.”
In a perfect world, security professionals would strive to create a risk-free environment. “We want it all down to zero,” Waters says. That’s not possible, however, because some degree of risk is inherent in every action an organization takes. “As challenging as it may seem, there are risks businesses are willing to accept,” Waters adds.
Too much caution blocks or degrades benefits, particularly when security mandates unnecessarily interfere with routine activities. Simply telling people what not to do is rarely effective, particularly if what they’re doing saves time and produces positive results. “We talk about Dropbox and things like that,” Waters says. “If your policies are too restrictive, people will find a way around them.”

If there’s an attack on the country, the military mobilizes. When a natural disaster strikes, recovery plans go into effect. Should an infectious disease start to spread, health officials launch a containment strategy. Response plans are critical to recovery in emergency situations, but when it comes to cybersecurity, a majority of industries are not paying attention.“The reality is no matter how amazing you are with your prevention capabilities, you’re going to be hacked,” said Mohammad Jalali, a research faculty member at MIT Sloan whose work is currently focused on public health and organizational cybersecurity. “Then what are you going to do? Do you already have a good response plan in place that is continuously updated? And communication channels are defined, and stakeholder responsibilities are defined? Typically the answer in most organizations is no.”To help address cybersecurity weaknesses in organizations, Jalali and fellow researchers at Cybersecurity at MIT Sloan Bethany Russell, Sabina Razak, and William Gordon, built an eight aggregated response strategies framework. They call it EARS.
Jalali and his team reviewed 13 journal articles involving cybersecurity and health care to develop EARS. While the cases are related to health care organizations, the strategies can apply to a variety of industries.
The EARS framework is divided into two halves: pre-incident and post-incident.
Pre-incident
1 — Construction of an incident response plan: This plan should include steps for detection, investigation, containment, eradication, and recovery.
“One of the common weaknesses that organizations have is they put together an incident response plan, but the problem is that documentation is usually very generic, it’s not specific to the organization,” Jalali said. “There is no clear, specific, actionable list of items.”
Make sure that everyone in the organization knows the plan, not just the employees in the IT department. Set clear channels of communication, and when assigning responsibilities, make sure they are clearly defined.
2 — Construction of an information security policy to act as a deterrent: Clearly defined security steps establish and encourage compliance.
“Many companies think that compliance is security,” Jalali said. “[That] if you just follow the information you’ll be taken care of.”
Don’t set the bar so low that the organization is not secure. Regulations should ensure an understanding of cyber threats. Establish motivational reasons for the response teams to follow reporting policies. Compliance should go hand in hand with continuous improvement.
3 — Involvement of key personnel within the organization: No matter the size of an organization, key leaders need to be educated on the importance of cybersecurity and be ready to act according to the response plan.
Leaders don’t have to be cybersecurity experts, but they need to understand the impact an incident will have on their organization. The more informed they are, the more involved they can be in a response plan.
4 — Regular mock testing of recovery plans: Recovery exercises help organizations stress-test plans and train employees on proper response protocols.
If the organization only tests its recovery plan during an actual emergency, it’s likely to run into serious issues, which could increase the amount of damage caused by the cyber incident.
The shift from a reactive to proactive stance can help an organization identify weaknesses or gaps in its recovery plan, and address them before an incident occurs.
Post-incident
5 — Containment of the incident: Containment involves both proactive and reactive measures.
It’s easier to cut off infected devices from a network if they’re already segmented from other devices and connections, prior to an incident. The researchers concede that it’s not always possible to segment networks, nor to immediately disconnect it from the whole system. At the very least, immediately report the infected device to the organization’s IT team to contain the incident.
6 — Embedded ethics and involvement of others beyond the organization: It’s important to remember that all of an organization’s stakeholders could be impacted by a cyber incident.
Promptly notify legal counsel and relevant regulatory and law enforcement agencies. Consider help from external resources and share information about the cyber threat.
7 — Investigation and documentation of the incident: Be timely and thorough; every step of the pre- and post-incident reaction should be documented.
The investigation should aim to find the root technical cause of the issue, as well as weaknesses that could prevent future attacks. Proper documentation is a necessity for this analysis.
8 — Construction of a damage assessment and recovery algorithm: Organizations should self-evaluate after the incident.
While computers are where cyber attacks happen, they can also be used to help with recovery. Organizations can leverage the power of computers, especially artificial intelligence, for real-time detection and containment of incidents.
“The commonly used frameworks for incident response strategies often miss this essential step,” Jalali said, “even though there are already AI-based products for this very purpose.”
