”Extortionware: 比Ransomware 更難處理。 首先單靠backup 已經不能成為擋箭牌， 當攻擊者進入你的網絡後， 他有可能將敏感資料送到你的「同業」手裡。 從MultiLayer Defense 到Zero Turst ..awareness Education.. 是攻/也是防..

Extortionware is a lot more difficult to predict and protect against. Extortionware attacks are usually highly targeted and are more about the retrieval of data than its destruction or encryption. Once cyber criminals have gained access to your system and taken sensitive information demands are made, usually for money, followed by a threat. For example, criminals may send your company’s intellectual property to competitors or distribute your data online unless they’re paid. However, money isn’t always the motivation behind this sort of attack. The 2015 information leak from website Ashley Maddison was carried out only after hackers gave the company a chance to change their operating policies. The policies weren’t changed and as a result around 36 million user details were released in a highly-publicised leak.

The main concern with this sort of attack is that a backup can’t be you get out of jail free card. Once the criminals have your data there is nothing you can do.

Đề Cambridge IELTS 14 Test 2 - passage 2:
BACK TO THE FUTURE OF SKYSCRAPER DESIGN

Answers to the problem of excessive electricity use by skyscrapers and large public buildings can be found in ingenious but forgotten architectural designs of the 19th and early-20th centuries

A. The Recovery of Natural Environments in Architecture by Professor Alan Short is the culmination of 30 years of research and award-winning green building design by Short and colleagues in Architecture, Engineering, Applied Maths and Earth Sciences at the University of Cambridge.
'The crisis in building design is already here,' said Short. 'Policy makers think you can solve energy and building problems with gadgets. You can't. As global temperatures continue to rise, we are going to continue to squander more and more energy on keeping our buildings mechanically cool until we have run out of capacity.'

B. Short is calling for a sweeping reinvention of how skyscrapers and major public buildings are designed - to end the reliance on sealed buildings which exist solely via the 'life support' system of vast air conditioning units.
Instead, he shows it is entirely possible to accommodate natural ventilation and cooling in large buildings by looking into the past, before the widespread introduction of air conditioning systems, which were 'relentlessly and aggressively marketed' by their inventors.

C. Short points out that to make most contemporary buildings habitable, they have to be sealed and air conditioned. The energy use and carbon emissions this generates is spectacular and largely unnecessary. Buildings in the West account for 40-50% of electricity usage, generating substantial carbon emissions, and the rest of the world is catching up at a frightening rate. Short regards glass, steel and air-conditioned skyscrapers as symbols of status, rather than practical ways of meeting our requirements.

D. Short's book highlights a developing and sophisticated art and science of ventilating buildings through the 19th and earlier-20th centuries, including the design of ingeniously ventilated hospitals. Of particular interest were those built to the designs of John Shaw Billings, including the first Johns Hopkins Hospital in the US city of Baltimore (1873-1889).
'We spent three years digitally modelling Billings' final designs,' says Short. 'We put pathogens• in the airstreams, modelled for someone with tuberculosis (TB) coughing in the wards and we found the ventilation systems in the room would have kept other patients safe from harm.

E. 'We discovered that 19th-century hospital wards could generate up to 24 air changes an hour-that's similar to the performance of a modern-day, computer-controlled operating theatre. We believe you could build wards based on these principles now.
Single rooms are not appropriate for all patients. Communal wards appropriate for certain patients - older people with dementia, for example - would work just as well in today's hospitals, at a fraction of the energy cost.'
Professor Short contends the mindset and skill-sets behind these designs have been completely lost, lamenting the disappearance of expertly designed theatres, opera houses, and other buildings where up to half the volume of the building was given over to ensuring everyone got fresh air.

F. Much of the ingenuity present in 19th-century hospital and building design was driven by a panicked public clamouring for buildings that could protect against what was thought to be the lethal threat of miasmas - toxic air that spread disease. Miasmas were feared as the principal agents of disease and epidemics for centuries, and were used to explain the spread of infection from the Middle Ages right through to the cholera outbreaks in London and Paris during the 1850s. Foul air, rather than germs, was believed to be the main driver of 'hospital fever', leading to disease and frequent death. The prosperous steered clear of hospitals.
While miasma theory has been long since disproved, Short has for the last 30 years advocated a return to some of the building design principles produced in its wake.

G. Today, huge amounts of a building's space and construction cost are given over to air conditioning. 'But I have designed and built a series of buildings over the past three decades which have tried to reinvent some of these ideas and then measure what happens. 'To go forward into our new low-energy, low-carbon future, we would be well advised to look back at design before our high-energy, high-carbon present appeared. What is surprising is what a rich legacy we have abandoned.'

H. Successful examples of Short's approach include the Queen's Building at De Montfort University in Leicester. Containing as many as 2,000 staff and students, the entire building is naturally ventilated, passively cooled and naturally lit, including the two largest auditoria, each seating more than 150 people. The award-winning building uses a fraction of the electricity of comparable buildings in the UK.
Short contends that glass skyscrapers in London and around the world will become a liability over the next 20 or 30 years if climate modelling predictions and energy price rises come to pass as expected.

I. He is convinced that sufficiently cooled skyscrapers using the natural environment can be produced in almost any climate. He and his team have worked on hybrid buildings in the harsh climates of Beijing and Chicago - built with natural ventilation assisted by back-up air conditioning - which, surprisingly perhaps, can be switched off more than half the time on milder days and during the spring and autumn.
“My book is a recipe book which looks at the past, how we got to where we are now, and how we might reimagine the cities, offices and homes of the future. There are compelling reasons to do this. The Department of Health says new hospitals should be naturally ventilated, but they are not. Maybe it’s time we changed our outlook.”

👨‍🏫 ในรูปได้ยกตัวอย่าง ช่องโหว่ของการเขียนโปรแกรม
ที่เปิดโอกาสให้ผู้ประสงค์ร้ายสามารถโจมตีด้วยวิธี
Command Injection
.
ช่องโหว่นี้เกิดจากในหลายๆ ภาษาโปรแกรมมิ่ง
ได้อนุญาติให้เรียกคำสั่งของระบบปฏิบัติการได้โดยตรง
ซึ่งสุ่มเสี่ยงให้ผู้โจมตีฉวยโอกาสนี้ฉีดคำสั่งเข้าไปในโค้ด
ด้วยการต่อท้ายด้วยข้อความ &&
จึงทำให้แทรกคำสั่งอันตรายเข้าไปได้ เช่น
:
del /F * บน window
หรือ rm -rf * บน linux
:
ในรูปได้ยกตัวอย่างโค้ดภาษา Java
ซึ่งทำงานบน Window
จะเห็นว่าสามารถใช้ && แล้วต่อท้ายด้วยคำสั่งอะไรก็ได้
เช่น && tasklist && dir เป็นต้น
.
แล้วถ้าโปรแกรมมันรันใน linux/Unix
ก็สามารถต่อคำสั่งเป็นลูกโซ่ด้วยข้อความ && หรือ ; ก็ได้
:
และไม่ใช่ Java ภาษาเดียว ที่มีช่องโหว่ประเภทนี้
มันเกิดได้หลายภาษา
ที่อนุญาติให้เรียกคำสั่งของระบบปฏิการโดยตรง
เช่น C#, Python, PHP และหลายๆ ภาษาที่ไม่ได้เอ่ยถึง
:
++++วิธีป้องกัน+++
🤔 ต้อง validate ข้อมูล input อย่างเข้มงวด เช่น
- กรอง input ที่เข้ามา กำหนดว่ามีอะไรได้บ้าง?
- input ที่เข้ามา ห้ามเป็นคำสั่งของระบบปฏิบัติการเด็ดขาด
- ห้ามมี && และ ; อยู่ใน input ที่เข้ามา
- เป็นต้น
.
😏 หรือจะเลี่ยงวิธีเขียนเรียกคำสั่งของระบบปฏิบัติการโดยตรง ไม่ต้องใช้ก็ย่อมได้

👨 🏫 In the photo, for example, the loophole of programming.
Open doors for the evil wills to attack by the way.
Command Injection
.
This loophole is born in many programming languages.
Permission to call direct order of operating system
Who randomly risked this opportunity attacker to inject an order into code.
By ending with a text &&
It's so dangerous to insert like
:
del / F F on window
or rm-rf rf on linux
:
In the picture, for example, Java language code.
Which works on Window
Will see that I can use && and then end up with any order.
Like && tasklist && dir etc.
.
And if the program runs in linux / Unix
Can continue with chain order with text && or; either.
:
And not Java the only language has this type of loophole
It can be born in many languages.
Allowing to call direct command of the operational system.
Like C #, Python, PHP and many languages that are not mentioned.
:
++++ How to prevent +++
🤔 Must strictly validate input information like
- Input filter that comes to determine what's available?
- Input that comes to prohibit is an order of an operating system.
- Don't have && and; stay input that comes.
- etc.
.
😏 or avoid the way to write, call direct command of an operating system. No need to use it.

ขั้นตอนการผลิต All-New 2019 BMW 3-Series Sedan (G20) production โฉมใหม่ล่าสุด (โดยละเอียด)

The BMW 3 Series Sedan represents the heartbeat of the BMW brand and the epitome of sporty driving pleasure in the premium midsize segment. The Mondial de l’Automobile 2018 is the venue for the world premiere of the seventh generation of the sports sedan. The new-edition 3 Series sees BMW building above all on the sporting tradition of the best-selling car. New powertrain technology and a body and chassis design geared squarely to maximising agility and dynamics create an ideal platform for an enthralling driving experience. The new BMW 3 Series Sedan comes as standard with a newly developed lift-related damper control system, which plays a significant role in giving the car its successful blend of sporting prowess and ride comfort. Options include an M Sport differential with electronically controlled locking function in the rear differential.

Precisely drawn lines and strikingly contoured surfaces mark out the exterior of the new BMW 3 Series Sedan, which showcases the brand’s new design language. The interior also has a clear, modern and sophisticated design.

Other features of the car that highlight its innovative character are BMW Operating System 7.0 and the BMW Intelligent Personal Assistant. Presented here for the first time, the Intelligent Personal Assistant responds to the prompt “Hey BMW”. The driver and passengers can speak with “him”, he is capable of learning and he gets better at his job all the time. The Intelligent Personal Assistant opens up a whole new avenue of interaction between the driver and car. It is a digital vehicle expert, knows the most important functions of the car and can explain them; if the driver wants to access navigation, office or entertainment functions, the BMW Intelligent Personal Assistant is there to help. One unique feature over other digital assistants is that drivers can give him a name, so they can activate him by saying “Hey Charlie”, for example, and therefore give him an even more defined personality. The Intelligent Personal Assistant awaits the driver’s every command and is always there to assist them. BMW is also taking a leading role in progress towards automated driving in the midsize class, thanks to a significantly extended range of driver assistance systems.

The latest results of BMW’s ongoing product offensive are taking centre stage at the brand’s Mondial de l’Automobile 2018 show stand in Paris. Emotion-packed design, pioneering technology and an even more richly engaging form of driving pleasure define the character of the new models BMW is presenting at the most important date on Europe’s 2018 car show calendar. The fresh arrivals introduce the brand’s new design language to a number of vehicle segments and represent significant advances in the areas of digitalisation, operation, sustainability and driving dynamics. For example, visitors to the Paris show will discover the first models to feature the new BMW Operating System 7.0, which creates a fully digital grouping of instrument cluster and Control Display and allows system operation to be adapted even more precisely to the driver’s personal preferences.

The BMW Group is set to revolutionise driving pleasure with the BMW Intelligent Personal Assistant. From March 2019, BMW drivers and passengers will be joined by an intelligent, digital character that responds to the prompt “Hey BMW”. This will mark the start of a new era for the BMW Group in which drivers will increasingly be able to operate their car and access its functions and information simply by speaking. Further innovations include BMW Laserlight and the Steering and lane control assistant, which are also available for other new models from the brand, plus the unique Reversing Assistant, which takes over steering for reversing manoeuvres in tight areas where visibility is restricted

The selection of series-production models due for market launch in the near future and innovative technology developments preparing to greet visitors to the Paris show from 4 – 14 October 2018 also reflect the rigorous implementation of NUMBER ONE - NEXT. The BMW Group’s corporate strategy spotlights development fields particularly relevant to the company’s future performance, i.e. design, automated driving, connectivity, electrification and services. The advances in these areas presented in Paris underscore the premium carmaker’s leading role in shaping the future of personal mobility. Also of key importance are BMW’s model offensive in the luxury segment (launched with the show premiere of the new BMW 8 Series Coupe), the continued expansion of the BMW X model family with the debut of the new BMW X5 and the addition of the new BMW M5 Competition (fuel consumption combined: 10.8 – 10.7 l/100 km (26.2 – 26.4 mpg imp); CO2 emissions combined: 246 – 243 g/km) to the BMW M GmbH line-up. The BMW Group’s leading role in premium-segment electric mobility is underscored most prominently in Paris by the presentation of the new generation of high-voltage batteries for the BMW i3 (fuel consumption combined: 0.0 l/100 km; electric power consumption combined: 13.1 – 13.0 kWh/100 km; CO2 emissions combined: 0 g/km) and BMW i3s (fuel consumption combined: 0.0 l/100 km; electric power consumption combined: 14.6 – 14.0 kWh/100 km; CO2 emissions combined: 0 g/km).
