Top Three Cybersecurity Threats You Should Mitigate Before It Is Too Late

Article | December 15, 2020

There are three significant and disruptive cybersecurity threats that are catching organizations of all types and sizes by surprise: Ransomware; Cloud misconfigurations; and Supply chain backdoors. Let me explain with recent examples and guide you on what you can do to avoid making other’s mistakes and falling victim to the threats. Let’s start with ransomware. It is one of the most disruptive risks facing your organization today. Why? Because it can literally bring your operations, no matter who you are, to a standstill and inflict significant cost, pain and suffering. Just look at the recent example of one organization. It was infected with ransomware, and IT systems were shut down for several weeks, bringing operations to a standstill. It had to gradually re-start systems over several more weeks. It estimates it will cost around $95 million from lost sales, recovery and remediation, impacting profitability. Also, it announced it will not be able to attain its growth plans for the year. Take another recent example. A three-hospital system was infected and IT systems were shut down and it could not accept any incoming patients for several days. It had to operate using paper, until gradually the IT systems were re-started over several days. Fortunately, in this case, the incoming patients turned away did not suffer any loss of life and were able to be diverted to other hospitals timely, but it could have been tragic. No organization is immune to ransomware and it can rear its ugly head anytime and inflict severe pain. There are many variants and each can be tweaked easily by the attackers to evade the defense. The Ryuk ransomware is an example of one that has already inflicted significant pain to hundreds of organizations this year in the U.S. and across the globe. Previously, the SamSam ransomware attacked a variety of organizations in the U.S. and Canada, and provided over $6 million in ransom payments and inflicted over $30 million in losses. Prior to that, NotPetya ransomware rapidly inflicted hundreds of organizations in various parts of the world, and caused over $10 billion in damages. The attackers are seeing that with ransomware it is quicker and easier to make the intrusion, and encrypt some of the data than try to exfiltrate all of it. They are asking themselves, why take all the time and trouble to look for all of the data and try to steal it, when only some critical systems and data can be locked up, until a ransom is paid? They are seeing that with ransomware there will be immediate adverse impact since the victim will not be able to access critical data and systems, and will not be able to operate. So, there is high probability the ransom will be paid to stop the pain and suffering, especially if the victim has cyber insurance in place. The organization is likely to use the insurance policy to pay the ransom, rather than continue to have its operations disrupted or shut down. They are also seeing that while most organizations have put in place various controls to prevent and detect data theft, they have not placed an equal weight to preventing and detecting ransomware. Most organizations have a lot of data and given all of the data thefts that have occurred and continue to occur and reported in the press, the bias has been to focus on data theft. But ransomware risk cannot be ignored or approached less seriously. Imagine that you are infected with ransomware and your people cannot access documents, files or systems, and operate. All critical files and systems are locked out from the ransomware encryption, and a ransom payment is demanded by the hacker for the keys to unlock the encryption. What if, it will take you days, weeks or months to recover? What impact would it have on your organization? You may think that you will be able to recover quickly from back up files and systems, but are you sure? The new ransomware variants are devised to hunt down and delete or encrypt backup files and systems also, and in some cases, first, before encrypting rest of the files and systems. The organization that was recently infected that estimates $95 million in financial impact from the ransomware thought it had the risk under control, until it was hit with the ransomware and realized it was not prepared to manage the risk. Now, let’s move to the threat from cloud misconfigurations. You are most probably in the cloud completely or partially. Whether you have completely outsourced your infrastructure and services to a cloud provider or are utilizing one partially, remember, ultimately, you own the cybersecurity and that you are responsible for security in the cloud, while the cloud provider is responsible for security of the cloud. While the cloud provider will provide perimeter security, you are responsible for security of your data, IP and other assets in the cloud, and are equally susceptible to attackers in the cloud as you are on the premises. Even if any of the “big six” cloud providers, such as Amazon Web Services or Microsoft Azure or others, provide the cybersecurity, attackers can exploit weak links in the chain, break in and steal data or cause other harm. A common weak link in the chain are misconfigurations of the various systems that the cloud provider makes available as part of its service. You are responsible for all of the configurations, not the cloud provider. So, if your team does not take the time to fully understand all of the configurations that are necessary and complete them timely, security holes will arise and remain open for the attackers to exploit. Just look at the recent example of an organization that fell victim where the data of over 100 million customers was stolen. This organization was using one of the “big six” cloud providers, but missed making all of the necessary configurations. A former employee of the cloud provider, who was familiar with the systems and configurations, discovered a misconfiguration in a web application firewall and exploited it to break in. The attacker then was able to query a metadata service to obtain keys and tokens, which allowed the attacker to query and copy storage object data and eventually exfiltrate it. This was a case where configuration errors in a web application firewall coupled with unrestricted metadata service access and other errors handed the attacker the keys to the kingdom for the theft of 100 million customers data. Other common cloud misconfigurations that create opportunities for attackers to exploit include: Unrestricted in bound access on uncommon ports Unrestricted outbound access Unrestricted access to non-http/https ports Unrestricted metadata service requests Inactivate monitoring of keys and tokens You may think that you do not have any misconfigurations in your cloud environment, but how do you know? The organization that recently lost 100 million customers data thought it had strong security in its cloud infrastructure, until it was hit with the data theft and realized it was not prepared to manage the risk. Now, let’s move to the threat from supply chain backdoors. No matter what type of organization you are or your size, you most probably have a supply chain, comprised of independent contractors, vendors or partners. Each of these could be the weakest link in the chain. In other words, the attackers may find that one of your suppliers may be easier to break into first because of weaker cybersecurity and may have privileged access to your organization, given their role and responsibilities. So why not first attack the weaker supplier, steal their privileged user credentials and use it to break into your organization and eventually attain the ultimate objective, steal data or commit other harm? Or they may find that one of your suppliers has part of your data in order to provide the outsourced service, so they can steal the data simply by breaking into the supplier with the weaker cybersecurity, so no need to attack you directly. There are many examples of supply chain risk, such as with a government agency, where the credentials of a background check vendor were first stolen to access the agency’s systems, then to move laterally and find other unprotected privileged users credentials to access databases and steal data of 21.5 million individuals, including fingerprints data of 5.6 million individuals. But just look at the recent example of an organization that had outsourced billing and collections to a supplier. This is a case where the attackers did not have to attack directly. In this case, attackers broke into the supplier and injected malicious code into the payments webpages managed by the supplier and stole credit card, banking, medical and other personal information, such as social security numbers, of 11.9 million consumers. The attackers had access to the supplier’s system for eight months, during which it skimmed the data being input by consumers on the payments webpages. So, while your cybersecurity may be in good shape, the weakest link in the chain may be one of your suppliers, who may unwittingly provide the attackers the backdoor into your organization or to your data or IP. So, ransomware, cloud misconfigurations and supply chain backdoors are three significant and disruptive threats facing your organization today that you should mitigate. What c

Guest Blog: Cyber security guidance for remote working

Article | December 15, 2020

In these challenging times, it’s sad to learn that cyber criminals are only increasing their activity as they look to capitalise on the Covid-19 crisis. With the NCSC (National Cyber Security Centre) issuing warnings of such activity on a daily basis, it’s important that we all work to protect our businesses from the damage of cybercrime. As many of us move to working from home, the opportunity for cyber attacks only increases, so it’s vital that we work together with our IT colleagues to adopt good cyber health practices. If you are working from home, you should only be using a VPN (Virtual Private Network) or a secure home network with strong end-to-end encryption; e.g. Office 365 SSL session. Don’t be tempted to use public wifi, as hackers can position themselves between you and the access point.

What Lessons Can We Takeaway from Las Vegas’ Recent Thwarted Cyberattack?

Article | December 15, 2020

Picture this: a news story detailing a cyberattack in which no data was exfiltrated, thousands (or even millions) of credit card details weren’t stolen, and no data was breached. While this isn’t the type of headline we often see, it recently became a reality in Las Vegas, Nev. On January 7, 2020, news broke that the city of Las Vegas had successfully avoided a cyberattack. While not many details were offered in the city’s public statement, local press reported that the attack did employ an email vector, likely in the form of a direct ransomware attack or phishing attack. The use of the word “devastating” in the public statement led many to believe ransomware was involved. This inference isn’t farfetched—and is likely a correct conclusion—given that cities throughout the U.S. have seen ransomware attacks on critical systems. Attacks that have cost those cities millions of dollars.

Noxious Zero-Click Attack: What Is It And How To Avoid It

Article | December 15, 2020

For years, we have been told that cyber-attacks happen due to human-errors. Almost every person has stressed about training to prevent cyber-attacks from taking place. We have always been on the alert to dodge errant clicks or online downloads that might infect devices with security threats. However, not all attacks need a user’s oversight to open the door. Although avoiding clicking on phishing emails is still significant but there is a cyber threat that does not need any human error and has been in the recent news. It is known as Zero-Click attack where some vulnerabilities can be misused by hackers to launch attacks even without interaction from the victim. Rather than depending on the hardware or software flaws to get access to the victim’s device, zero-click attacks eliminate the human error equation. There is nothing a victim can do once coming into the limelight of the hacker. Also, with the flourishing use of smartphones around the world that entails all the personal information and data, this thread has expanded enormously. How Zero-Click Attacks Occur? The core condition for successfully pulling off a zero-click is creating a specially designed piece of data which is then sent to the targeted device over a wireless network connection including mobile internet or wifi. This then hit a scarcely documented vulnerability on the software or hardware level. The vulnerability majorly affects the messaging or emailing apps. The attacks that have begun from Apple’s mail app on iPhone or iPad, have now moved ahead on Whatsapp and Samsung devices. In iOS 13, the vulnerability allowed zero-click when the mail runs in the background. It enables attackers to read, edit, delete, or leak the email inside the app. Later these attacks moved to Samsung’s android devices having version 4.4.4 or above. The successful attacks provide similar access to the hackers as an owner, entailing contacts, SMS, and call logs. In 2019, a breach on Whatsapp used the voice call functionality of the app to ring the victim’s phone. Even if the victim didn’t pick the call and later deleted it, the attacks still installed malicious data packets. These grants access to the hacker to take complete control of call logs, locations, data, camera, and even microphone of the device. Another similar attack had happened due to the frangibility in the chipset of WI-FI that is used in streaming, gaming, smart home devices, and laptops. The zero-click attack blooms on the increase of mobile devices as the number of smartphones have reached above 3 billion. How To Avoid Zero-Click Attacks? Most of the attacks of zero-click target certain victims including corporate executives, government officials, and journalists. But anyone using a smartphone is a possible target. These attacks cannot be spotted due to the lack of vulnerabilities. So the users have to keep the operating system along with the third-party software updated. Also, it is a must to give minimal permissions to apps that are being installed on the device. Moreover, if you own a business and are afraid of the zero-click attacks on your company’s app, you can always seek IT consultations from top-notch companies orhire developersthat will help in developing applications with hard-to-creep-into programming languages where detecting an attack is efficient.
