SamSam Ransomware variant – December 3, 2018

Preface:

The Department of Homeland Security urge the world and United state staying alert of new wave of cyber attack.

Technical details:
SamSam ransomware is a custom infection used in targeted attacks, often deployed using a wide range of exploits or brute-force tactics. Most likely the goal of the action is interfere the society stability. It can widespread impact on political stability.

Recommendations:
1. Maintain up-to-date antivirus signatures and engines.
2. Keep operating system patches up-to-date.
3. Disable File and Printer sharing services.
4. Monitor users’ web browsing habits; restrict access to sites with unfavorable content.
5. Enforce Awareness training.

Credit reporting agency TransUnion – personal data security flaw (Nov 2018)

Preface:
Transunion offers total credit protection all in one place from credit score, credit report and credit alert. On June 25, 2015, TransUnion became a publicly traded company for the first time, trading under the symbol TRU.

Who is CreditGo?
CreditGo provides free access to credit circular reports and credit scores for Hong Kong residents. Meanwhile the credit information provided by CreditGo comes from TransUnion.

Data privacy leakage incident:
The Hong Kong arm of American consumer credit reporting agency TransUnion was forced to suspend its online services on Thursday after a local newspaper was easily able to access the personal data of the city’s leader and finance minister.

What is the reason?
Incorrect program logic from online web application cause database leak.

Remedy:
Suspend online services.

Comments:
Refer to attached diagram, it is hard to avoid your data personal privacy leakage since when bank or financial institute check the information of a person. It is because a duplicate copy will be generate.
Business world and our daily life is insane now!

Who hinder smart city development?

Preface:

The desire of human being is infinite. It create motivation and innovation. However it embedded greedy and selfishness.

Smart city major domains

In high level point of view, it is easy to interpret smart city major domains. They are Analytics,Transportation,Health & Environment.

You might ask, where is cyber security? I assumed that cyber security equivalent as a hidden parameter. They will pop up during you conduct a gap analysis (see below diagram for reference).

Who causes security gap?

When functional requirements hits design limitation, you can set out strategic solution conduct the remedy, along with a time frame for meeting those objectives.

However the unknown parameters will impact business decisions because of their expectation and budget concerns. As a result, the technology and cyber security gap will carry forward with development cycle.

A study from Hewlett Packard in 2016 concluded that 70 percent of IoT devices contain serious vulnerabilities.

The IoT devices and smart city relationship

IoT involves adding internet connectivity to a system of interrelated computing devices, mechanical and digital machines, objects, animals and/or people. The Internet of Things (IoT) form a bridge in between human and machine. As of today, key terms so called ECO system explicitly describe above mechanism. The key technology behind the success of smart city initiatives is the IoT devices. Thereby IoT devices similar an organ inside the human body. The communication in between IoT devices and IoT ECO system like human blood vessel. So, if the smart city infrastructure characteristics like human. And therefore it is hard to avoid sick and illness.

IoT security

When a electronic device has ability for external communications. A specific TCP or UDP port will operate in listen state. The traditional best practice will deploying Firewall and antivirus software. Since IoT devices OS footprint is small. For example a webcam, even though the manufacturer want to install a defense mechanism. However the design limitation restrict or without space. It could not fulfill the requirement. So IoT devices are the top attack target by cyber criminals. As we know, a so called botnet army will be control by attacker command and control server remotely.

For my observation by far, the IoT security awareness was alerted by security researcher since 2010 (see below diagram for reference).

Perhaps the product development and business trend run in fast way. The smart city and artificial intelligence boots up the growth. As of today, IoT devices implementation covered all around the world. Moreover IoT device owner learn from practice in result reduced the cyber attack hit rate. For instance do the patch management. But due to on demand business economic model (multi vendor, without common standard). It has difficult to sharpen the preventive and detective control in IoT world.

IoT now transform to 4th generation (IIoT). The Industrial Internet of Things (IIoT) or Industry 4.0 refers to interconnected sensors, instruments, and other devices networked together with computers’ industrial applications. The IIoT manufacturer especially SCADA system keen to partnership with famous antivirus vendor. For instance Siemens electronic in high priority installed Trend Micro antivirus products. However the fundamental design of SCADA systems did not focus cyber security . In light of that, on Aug 2018, the Internet Society’s Internet Engineering Task Force is working on IoT standards in areas including authentication and authorization, cryptography for IoT use cases and device life cycle management. Do you think the plethora of IoT security standards could make it difficult for a global IoT standard to emerge?

Internet of Things Embedded Operating Systems is Bad News for the Safety

IoT devices tend to use a type called RTOS, which officially is short for Real-Time Operating System. Unofficially it stands for Not-a-Full-Featured Operating System.

Below diagram bring an idea to you for reference. The Smart TVs, new generation of washing machines, Smart doorbells, Artifical intelligence lawn sprinkler systems, CCTV cameras, smart meter, motion, humidity and temprature sensor and webcam has embedded OS installed. Above IoT devices are capable for WiFi or TCP/IP connection protocol function. TCP protocol integrate to electonic devices was the best of times. But it was the worst of times since it will encountered vulnerability and Zero day attack. But it was the age of wisdom!

FreeRTOS – A real-time operating system microkernel has been developed by chip companies for over 15 years. As of today, IoT industry especially webcam, Smart home devices are deploy this operating system. But serious security flaws in FreeRTOS. The most recent known vulnerabilities are shown as below:

Remote code execution vulnerabilities: CVE-2018-16522, CVE-2018-16525, CVE-2018-16526, CVE-2018-16528.

Denial of service: CVE-2018-16523

Design flaw allow information disclosure: CVE-2018-16524, CVE-2018-16527, CVE-2018-16599, CVE-2018-16600, CVE-2018-16601, CVE-2018-16602, and CVE-2018-16603

Smart city open data platform

Basically Open data is just that – open. The baseline definition is anyone can access, share and use it free of charge to better connect and interact with their cities. Applications include real-time bus timetables, weather report and public safety information sharing initiatives. Basically Open data is just that – open. The baseline defintion is anyone can access, share and use it free of charge to better connect and interact with their cities. Applications include real-time bus timetables, weather report and public safty information sharing initiatives. But the open data platform not limit above data criteria. So it make people including myself has personal data privacy concerns.

It was the worst of times since it make people concerning personal data privacy . But it was the age of wisdom!

In New York City, open data is law, rather than just a policy. In order to driven the development of smart city. The Domain knowledge expert has the following recommendations.

Summary:

Who hinder smart city development? We can say it is the technology limitation and personal data privacy concerns. Whether it was the worst of times on these matters . But it was the age of wisdom!
