The security update of Microsoft this week included provides support to control usage of Indirect Branch Prediction Barrier (IBPB) within some AMD processors (CPUs) for mitigating CVE-2017-5715. Apart from that it also provides Windows Client Guidance for IT Pros to protect against speculative execution side-channel vulnerabilities. However I was wondering the mitigation plan coverage provided by AMD?
A insidiousness of the SIMD instruction extensions of ARM, MIPS, and x86? Does AMD cover this part because SIMD Instructions considered harmful?Any advice or we just ignore it?

Traditional layer 2 communication system (without TCP/IP), proprietary OS system and without internet technology similar as a antibody protect the important facilities especially electricity power supply, water supply and natural gas facilities. But the element of civilization like a non stop vehicles moving forward. Whereby the man kind went through industrial revolution till today digital technology revolution. Our daily lifes support by electricity, water and natural gas. In order to maintain the stability and quality of those resources of supply. A analogue to digital (electronics) conversion was done, Thereby those facilities are under governance and control by PLC and SCADA today. However a design limitation was found since the components embedded Microsoft operation system and Linux opensource. So we heard power facilities encountered cyber attacks. This time the design flaw found in Allen Bradly PLC product. Regarding to the CVE reference number, we found that the vulnerabilities reported last year and believed that vulnerabilities has been fix. But a reminder to all of us is that vulnerabilities not limit to your office automation system and smartphone.The vulnerabilities are go with us daily.
Below url provides an overview of cyber attack on nuclear power facilities for reference.

The design objective of the Command Line Parser is used to parse the command line arguments. The parser parsing a string and returns an object representing the values extracted. This is the the regular expression design objective. The Cisco IOS XE is a train of Cisco Systems’ widely deployed Internetworking Operating System (IOS), introduced with the ASR 1000 series. IOS XE is a combination of a linux kernel and a (monolithic) application (IOSd) that runs on top of this kernel. The goal of IOS SE aim to integrate the IOS feature set for routing and switching cope with modern business critical applications. Vulnerability found daily we have not surprise. A CLI command injection vulnerability has been found on CISCO IOS XE this month. For more details, please find below url for reference.
Believe that ATM scammer or criminal activities will be signigicant dropped after ATM thief are under sentence. It looks that I am overlook the attraction of bank note since a new jackpotting malware is under development. I surprise to me that the malware originate country is in Hong Kong. We known that bank of China did the system update (perhaps including ATM machine) during easter Hoilday. The ATM infrastructure looks prefect under the custodiance of Hong Kong monetary authority. However there are system design bugs and limiations on both hardware and software so it lure the hacker interest. It bring misunderstanding of ATM technology to the IT people so far, ATM archiecture is old fashion. But the truth is that ATM system architecture has been line up with Microsoft client-server architecture for financial applications on the Microsoft Windows platform in last decade. Threat actors can appear all around the world. The highlight of this news incidentally let the world know that Hong Kong is also a technology development zone. It is not only limit to business financial area.

- Allowing the attacker to execute arbitrary code on the device.
- Causing an indefinite loop on the affected device that triggers a watchdog crash.
Perhaps the side effect of this vulnerability looks dangerous especially allowing the attacker to execute arbitrary code on the device.
But there is quick way to do the remedation of this vulnerability.
a. Go to your router configuration mode and input no vstack command.
b. Since victim report that a special message show on the console screen. And therefore it is recommended to use your ios backup file to replace existing ios.

Blockchain technology contains advanced security features fundamentally. However the heist occurs in such secure platform are in frequent. The questions of a retrospective and why was hacked? It proof that the problem not given by blockchain technology design flaw. Most likely the root causes are given by end point (client side), operation management (show the privilesge credential in the system event log). Rumors happened yesterday, verge user feared the attacker might use his dominant network position to siphon funds from their accounts. Verge technical team announce that it is a hash attack and it only some blocks were affected during a 3 hour period, not 13 hours. But what do you think? Do you think there is a zero day happens in e-wallet? Headline News can be found in following url.
