Bitcoin exchanges must remain vigilant to low value coins

Heard that a vulnerability found on cryptocurrency (FuturXE (FXE)). The problem is that smart contact designer make a programming logic mistake. Department of Homeland Security confirm the bug this week. (CVE-2018–12025) –

The vulnerabilities and cyber attack looks never stop so far. Do you still remember virtual currency exchange Coincheck lost $400 million in NEM cryptocurrency in Jan 2018?

The hack only involved NEM, because the security breach was caused by the lack of strong security measures of Coincheck with regards to their implementation of NEM, lacking the use of mutlisignature support or a cold wallet.

It looks that criminal group will be intereted of low market value cryptocurrency. For instance, CVE-2018-10468 hacker exploits useless token combine with vulnerability steal the token. Coincheck lost $400 million in NEM but the market price of each coin is in lower value.

FutureXE market price equal to zero buy still avaiable to buy on the market. I think this type of coins will be lure criminal group interest. The fact is that this type of coins willl be exploits for money laundering. Since the coin has vulnerability occured, criminal group can hiring hacker to steal the coin and waiting for bitcoin exchanges reimburse the fund to achieve the money laundering objective.

June 2018 – Red Shell service arousing public question!

DNS logs explicitly shown the internet user activities. For instance a malicious network traffic that can be identified in DNS logs. The technical details includes command and control (C2) traffic of the following cyber attacks.
Ransomware, malicious ads and redirects, exploit kits, phishing, typosquatting attacks, DNS hijacking; denial of service (DoS) attacks; and DNS tunneling.

Pi-hole is a Linux network-level advertisement and internet tracker blocking application which acts as a DNS sinkhole. DNS Sinkholing is a mechanism aimed at protecting users by intercepting DNS request attempting to connect to known malicious or unwanted domains and returning a false, or rather controlled IP address. The controlled IP address points to a sinkhole server defined by the DNS sinkhole administrator.

The Sinkhole server can be used to collect event logs, but in such cases the Sinkhole administrator must ensure that all logging is done within their legal boundaries and that there is no breach of privacy.

Red Shell helps PC & console games uncover where their players
come from through reliable attribution. Their system architecture build by PI-HOLE and bind opensourece application. Meanwhile PI-HOLE and BIND can do reverse engineering. It can do the end point monitoring, aim to keep track the customer behaviour.

A concerns of public and question the analytics package provided by Innervate, Inc., to game publishers.
Innervate, a Seattle-based company founded to help game makers reach more customers, is launching its new Red Shell service today.

My reflections – Why do we require complete artificial intelligence into daily life?

The important thing is to never stop questioning, said Albert Einstein.

Since there is no prefect design items in the world. and therefore bug fix or so called software patch update is the acceptable method. So when I heard Apple issued the security update for Siri (speech recognition application program). As usual I will be interested of the techincal details of the security update. But my consideration this time not on cyber security. My question is that why do we require complete artifical intelligence into daily life. As we know after Apple Siri, Microsoft launched Cortana, Amazon launched Alexa. The speech recongnition was significant success (see attached diagram). The aim of this function not target smartphone only. The major goal is integrate this function into Artifical Intellgence system. The situation of today technology world similar following circumstances. That is once we accept our limits, we go beyond them. But my personal opinion is that we are on the way go to simple thinking logical model. The logical thinking steps will be replaced and transfer to another parties.  In fact that it will enhace the security and operation effeciency. Meanwhile the resources in the world is limit. For instance the existing resources in normal non AI environment can be consume for 100 years. But when we integrate our life to AI, how long will be maintain in the consuming cycle?

Why do we require AI (Artifical intelligence)?


When a child is born, his destiny is learning. He requires continuous learning the knowledge. His objective looks simple because his goal is survival.

What is the objective of AI (Artificial Intelligence)?

The aim of the development of AI it is to mimic in machines the “intelligent” behavior of humans.

The major element of AI (Artifical Intelligence). It is learning. The computer similar a baby, the world empower the knowledge to him. As a result, his learning path including human behaviour, human thinking logic, languages, decision making logic. But how does artificial intelligence do the correct decision not jeopardize the world? This is the ethics.

Does science world ignore the key element before A successful build?

The super computer contains super processing power with high calulation speed. It is without difficulties to do the data analytic. But emulate a human logic thinking require huge volume of data set includes human behaviour data set, differect catagories of data, the historical of crime activities, business decisions logic,…etc.

Hey! Is there any contradition found on this place. For instance, a ethic will be bound to human logical thinking? For instance, you visit library to read the book. This is equilvant learning mode. But in the libray, the book could not contain personal data, personal behaviour acivities provides. So this is the classical learning mode.

You pick up sister or brother letter in the mail box. The ethics will guide you are not allow to open the letter, right? But why does the artificial intelligence have this privileges to read the personal data? The AI read the personal data without consent!

Intelligence is not bestowed by whom, but are the condition of each person is born with and enjoys. However the whole way is for human survival in the earth. If machine contains artifical intelligence. From techincal point of view, it looks like human build a new competitor for himself? The major point is that AI will be wind their way to survivail in the world once their technology is mature.

I am not speaking the conspiracy. It is reality since they are in the machine learning phase. Their evolutions are shown as below:

1st Generation

Data science: Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from data in various forms, both structured and unstructured,similar to data mining.

2nd Generation

Machine learning: Machine learning is a subset of artificial intelligence in the field of computer science that often uses statistical techniques to give computers the ability to “learn”.

Final stage

Artifical intelligence: Artifical intelligence is intelligence demonstrated by machines, in contrast to the natural intelligence (NI) displayed by humans and other animals.

Source of data of machine learning nowadays

Datasets of population, economic and development across the world:

Data operate in educational institutions and education demographics from the US and around the world:

The collection of social, economic and population data in UK:

The national crime statistics, with free data available at national, state and county level:

Information gathered by NASA’s space exploration missions:


Human pollute the world because of living standard growth and modern industries.
Artificial intelligence in final phase will be …..
A song is on the way!

Don’t kill the world, don’t let it down. Do not destroy basic ground…..

Who is most faster? Crossbar SW or PCR?


China won 1st of the TOP500 list of the world’s top supercomputers on June 2016. Can we say PCR is the mainstream? Or still keep crossbar switch deployment?

Who’s ready to break a record today?

IBM announced on June 2018. SUMMIT’s do mathematical calculations at the rate of 200 quadrillion per second, or 200 petaflops.

The Sunway TaihuLight has a processing speed of 93 petaflops.

What are the key components of the Chinese supercomputer architecture?

Do you remember the Parallel Capacity Resource (PCR) clusters? The mature technology found in 2002. The success of the PCR clusters was followed by the purchase of the Multiprogrammatic Capability Resource (MCR) cluster in July, 2002 from Linux NetworX (see below diagram). The PCR cluster debuted as the Top 500 Supercomputers list in November, 2002.

The Sunway TaihuLight uses a total of 40,960 Chinese-designed SW26010manycore 64-bit RISC processors based on the Sunway architecture.Each processor chip contains 256 processing cores, and an additional four auxiliary cores for system management (also RISC cores, just more fully featured) for a total of 10,649,600 CPU cores across the entire system.

Parallel Capacity Resource (PCR) cluster architecture create the mystery power!

The differences between China supercomputer and traditional mainframe supercomputer.

I speculated that China supercomputer architecture established by Parallel Capacity Resources Cluster concept for system development. Some technical details as finger print to proof of concept. Detail is shown as below:

1. Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes.

2. System OS not mentioned on technical report, however I believed that the OS kernel development on top of System V (Unix/Linux).

Programming lanugage:

X10 is an open-source programming language being developed at IBM Research in collaboration with academic partners. The programming language designed specifically for parallel computing using the partitioned global address space (PGAS) model. A computation is divided among a set of places, each of which holds some data and hosts one or more activities that operate on those data. It has a constrained type system for object-oriented programming, a form of dependent types.

System Architecture:

Processor Security – When a partition is booted, the hypervisor initializes all of the hardware registers available to the partition to a known state. Later, when the partition is no longer running on a hardware thread, the hypervisor copies the current register contents to a save area associated with this specific logical processor. This copying of the registers is done for both dedicated and shared processor partitions. These virtualized registers are maintained in hypervisor memory (physical real memory) so that the memory cannot be altered.

Memory – The HPT (Hardware Page Table) is a mapping from the partitions address space to physical real addresses. Each partition that is created has its own HPT. Whenever a partition is running on a hardware thread, the hardware always uses the information from that partition’s HPT to translate the addressing. The HPT is part of the firmware memory usage on the server and since it is maintained only in real memory, only the PowerVM hypervisor can make changes to the HPT.

Linux NetworX and next generation

The specific cyber security did not mentioned since it priority to focusing the processing power. Should you have interest of the parallel capacity resource (PCR) computer architecture. Please refer below URL for referemce.

29th May 2018 – VMware security update – CVE-2018-6964

Found VMware Horizon Client (Linux) contains design weakness causes privilege escalation vulnerability. I speculate that the vulnerability only happened on Horizon client for Linux. And therefore it can’t bring the IT guy attention. But do not ignore this vulnerability. As we know, ESXi 6.5 could allow an autenticated VNC session to cause a heap overflow via specific set of VNC packes resulting in heap corruption. But hacker would exploit this deisgn bug. Meanwhile the environment must fulfill the requirement. VNC must be enabled. Apart from that ESXi must configured to allow VNC traffic through the build in firewall. As a matter of fact, IT operations would like to increase their fexibility. And sometimes enable this function in data center. If this is the way or you require to use VNC for remote access. Then you must stay alert.
If this is not a require function, it is recommend to disable it.

For the vulnerability details found on 29th May 2018. Techncial detials is shown as below:
