Easily Bypass iPhone Encryption – Apr 2018

Headline news report that law enforcement agencies across the country have purchased GrayKey, a relatively cheap tool for bypassing the encryption on iPhones, while the FBI pushes again for encryption backdoors. It looks that a great opportunities for technology firm. It can receive rewards. It is indeed a win win situation. Tech firm can earn money. The court is able to collect the evidences to do the right judgement. Meanwhile, I was wonder whether this is the only way to open the backdoor? As we know, jailbreak the iPhone not a secret. The default password looks easily to collect. So far, the cheap tool to do the magic are available. Perhaps you cannot unlock the phone directly. However you are able to get in (see attached diagram for reference). I beleive that there are more possible way and idea will be coming soon.

Microsoft security update – April 10, 2018 – KB4093112

1 Comment

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?

Allen Bradley – The design flaw of the programmable logic controller – system vulnerability

1 Comment

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.

Bank ATM Framework QUICK TOUR

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.
