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

Article | January 19, 2021

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.

Information Security Management System to Protect Information Confidentiality, Integrity, and Availability

Article | June 18, 2021

In this modern world of technology, ensuring information security is very important for the smooth running of any organization. Unfortunately, there are many information/cyber security threats, including malware, ransom ware, emotet, denial of service, man in the middle, phishing, SQL injection, and password attacks. Whatever your business is, no doubt, it can collapse your business and your dreams. However, the severity of its after-effects depends upon the type of business you do. As information security threat has become a hurdle for all organizations, companies must implement an effective information security management system. In 2019 alone, the total number of breaches was 1473. It is increasing every year as businesses are doing digital transformation widely. Phishing is the most damaging and widespread threat to businesses, accounting for 90% of organizations' breaches. This article lets you understand what ISMS is and how it can be effectively implemented in your organization. Information Security Management System (ISMS) According to ISO/IEC 27001, Information Security Management System (ISMS) refers to various procedures, policies, and guidelines to manage and protect organizations' information assets. In addition, the system also comprises various other associated resources and activities frameworks for information security management. Organizations are jointly responsible for maintaining information security. People responsible for security in an organization ensure that all employees diligently meet all policies, guidelines, and other objectives regarding protecting information. Also, they safeguard all assets of the organization from external cyber threats and attacks. The goal and objective of the system are to protect the confidentiality, integrity, and availability of assets from all threats and vulnerabilities. Effectively implementing an information security management system in your organization avoids the possibility of leaking personal, sensitive, and confidential data and getting exposed to harmful hands. The step-by-step implementation of ISMS includes the process of designing, implementing, managing, and maintaining it. Implementing ISMS in Organizations The standard for establishing and maintaining an information security management system in any organization is ISO 27001. However, as the standard has broad building blocks in designing and implementing ISMS, organizations can shape it according to their requirements. Effectively implementing ISMS in organizations in compliance with ISO 27001 lets you enjoy significant benefits. However, an in-depth implementation and training process has to be ensured to realize these benefits comprehensively. Therefore, let us look into how an information security management system can be successfully implemented in your organization. Identification The first step in implementing ISMS is identifying the assets vulnerable to security threats and determining their value to your organization. In this process, devices and various types of data are listed according to their relative importance. Assets can be divided across three dimensions: confidentiality, integrity, and availability. It will allow you to give a rating to your assets according to their sensitivity and importance to the company. Confidentiality is ensuring that the assets are accessed by authorized persons only. Integrity means ensuring that the data and information to be secured are complete, correct, and safeguarded thoroughly. Availability is ensuring that the protected information is available to the authorized persons when they require it. Policies and Procedures and Approval from the Management In this step, you will have to create policies and procedures based on the insights you got from the first step. It is said to be the riskiest step as it will enforce new behaviors in your organization. Rules and regulations will be set for all the employees in this step. Therefore, it becomes the riskiest step as people always resist accepting and following the changes. You also should get the management approval once the policies are written. Risk Assessment Risk assessment is an integral part of implementing an Information Security Management System. Risk assessment allows you to provide values to your assets and realize which asset needs utmost care. For example, a competitor, an insider, or a cybercriminal group may want to compromise your information and steal your information. With a simple brainstorming session, you can realize and identify various potential sources of risk and potential damage. A well-documented risk assessment plan and methodology will make the process error-free. Risk Treatment In this step, you will have to implement the risk assessment plan you defined in the previous step. It is a time-consuming process, especially for larger organizations. This process is to get a clear picture of both internal and external dangers that can happen to the information in your organization. The process of risk treatment also will help you to reduce the risks, which are not acceptable. Additionally, you may have to create a detailed report comprising all the steps you took during the risk assessment and treatment phase in this step. Training If you want effectively implement all the policies and procedures, providing training to employees is necessary. To make people perform as expected, educating your personnel about the necessity of implementing an information security management system is crucial. The most common reason for the failure of security management failure is the absence of this program. Implementing ISMS Once policies and procedures are written, and necessary training is provided to all employees, you can get into the actual process of implementing it in your organization. Then, as all the employees follow the new set of rules and regulations, you can start evaluating the system's effectiveness. Monitoring and Auditing Here you check whether the objectives set were being met or not. If not, you may take corrective and preventive actions. In addition, as part of auditing, you also ensure all employees are following what was being implemented in the information security management system. This is because people may likely follow wrong things without the awareness that they are doing something wrong. In that case, disciplinary actions have to be taken to prevent and correct it. Here you make sure and ensure all the controls are working as you expected. Management Review The final step in the process of implementing an information security management system is management review. In this step, you work with the senior management to understand your ISMS is achieving the goals. You also utilize this step to set future goals in terms of your security strategy. Once the implementation and review are completed successfully, the organization can apply for certification to ensure the best information security management practices. Summing UP Organizations benefit from implementing and certifying their information security management system. The organization has defined and implemented a management system by building awareness, training employees, applying the proper security measures, and executing a systematic approach to information security management. Thus implementation has the following benefits: Minimized risk of information loss. The increased trust of customers in the company as the company is ISO/IEC 27001 certified. Developed competencies and awareness about information security among all employees The organization meets various regulatory requirements. Frequently Asked questions What are the three principles of information security? Confidentiality, integrity, and availability (CIA) are the three main principles and objectives of information security. These are the fundamental principles and the heart of information security. How does information security management work? Information security management works on five pillars. The five pillars are assessment, detection, reaction, documentation, and prevention. Effective implementation of these pillars determines the success of the information security management in your company. What are the challenges in information security management?
