Mua "Nền Quốc Phòng Vũ Khí Tối Tân"
Trong nền "kỹ thuật rình mò" hiện đại, một cái điện thoại bình thường của chúng ta chính là tên "gián điệp" nằm vùng (hay nội gián) của nhà nước an ninh và tập đoàn lợi nhuận.
Nhưng khi kỹ thuật điện toán và liên tín này được tận dụng trong hệ thống vũ khí hiện đại, nó không chỉ còn là "nằm vùng trộm cắp rình mò" như PlaceRaider, mà nó trở thành "thượng cấp" của vũ khí đó. Nghe có vẻ lạ lùng và "thuyết âm mưu" chăng?
Sự kiện vừa qua, theo tờ Behörden Spiegel của Đức- biệt đội quốc phòng tên lửa của Đức, với dàn vũ khí tối tân do Mỹ chế tạo đã bất ngờ "nhận lệnh khai hỏa" từ một "cấp trên vô danh"!
Hàm ý chính trị của sự kiện này còn nhiều bàn cãi và "điều tra" của nhà nước Đức. Tuy nhiên nó cho chính chúng ta một bài học về CHẤT VẤN và LÝ GIẢI, ít nhất ở tầm căn bản kỹ thuật thông dụng: Khi chúng ta mua một cái Di Động, hay Laptop, và nhất là một ứng liệu (apps) hay hệ điều hành (OS) với "bản quyền" và nội dung kín...không phải ứng liệu mở (open source như Linux, android v.v) LÀM SAO CHÚNG TA BIÊT ĐƯỢC TRONG ĐÓ CÓ NHỮNG CƠ PHẬN ĐẶC BIỆT hay ỨNG LIỆU HIỆU LỆNH ĐẶC BIỆT gì khác hay không? (-How Computer Manufacturers Are Paid to Make Your Laptop Worse)
Ngay như động cơ và máy cũng như hệ điều khiển tự động của các loại máy bay hàng không dân dụng như Air Bus, Boeing, Rollroys v.v đều có gắn cơ phận và ứng liệu vệ tinh để trực tiếp giao chuyển tín hiệu về...các công ty chế tạo...Có nghĩa là "quyền theo dõi và ngay cả điều khiển" máy bay không còn nẳm độc quyền nơi CHỦ NHÂN, NGƯỜI MUA, mà "quyền và khả năng" này vẫn nằm lại nơi NGƯỜI CHẾ TẠO ra nó!!!
Vũ khí tối tân còn cao cấp tế vi hơn rất nhiều. Nghĩa là nên HIỂU rằng khi MUA vũ khí tối tân của kẻ khác tức là cũng đồng nghĩa không chỉ "cõng rắn" vào nhà mà khả năng trở thành "nô lệ tay sai"vô tình hoặc bất đắc dĩ cho kẻ BÁN!
Quí vị cứ nhẩn nha, chẳng cần vội, cứ chất vấn, tham khảo thêm và suy ngẫm lãnh vực "khoa học kỹ thuật thông tin hiện đại" này trong một "NỀN QUỐC PHÒNG MUA VŨ KHÍ TỐI TÂN."

Germany, Hacking, Military, Security, TurkeyThe German Patriot air and missile defense systems, stationed at the Turkish border with Syria, have carried out “unexplained” commands allegedly issued by unknown hackers, according to a German media report since rebutted by the government.
The US-produced missile systems, belonging to the German Bundeswehr armed forces and based on the territory of NATO ally Turkey since 2013, have been compromised, according to a report in the German Behörden Spiegel.
As a result, the systems, consisting of six launchers and two radars, reportedly carried out “unexplained” orders, the publication claimed, providing no further information on the kind of commands.
A spokesman for the Federal Department of Defense however rebutted the report on Tuesday, saying that “there is no base data” for an extremely improbable attack, Die Welt newspaper reported.
According to the magazine, there could be two weak spots in the system, which was first used by the US army over 30 years ago. The first one is the Sensor-Shooter-Interoperability (SSI), which stands for the information exchange between the missile launcher and its control system. Another weakness could be in computer chips, which are responsible for the guidance of the weapon.
Compromising military systems is not something that an amateur hacking group would have the skills to do, or would want to admit doing, believes computer security consultant and former UK-based computer hacker Robert Jonathan Schifreen. He told RT that the “unexplained” commands from the hackers mentioned in the report, while “certainly worrying,” could not possibly be anything of much significance.
“These systems are not linked to public networks, they require special codes to fire the missile, which only a certain number of people have, and you generally need the code from two or three people to fire it, or to do anything that is of significance,” Schifreen said. “I don’t think it’s actually happened, which is not to say that some of these systems are not hackable in some way. It is possible in some way perhaps to detect the presence of it, but anything more than that is going to take some serious skills.”
“It is certainly the case that foreign governments, intelligence agencies do try to hack into these systems, and it may well be that the software built into the missile has been compromised in some way by some foreign government,” he added.
But the main risk, says security expert Billy Rios, stems from software upgrades that provide smart weapon capabilities to the weaponry, along with incompetence of local operators who have only basic understanding of how these military systems work and connect to each other.
“Each individual weapons system presents a different set of systems that someone would have to penetrate in order to take control of it,” Rios told RT. “It is surprising how these things eventually get connected to the internet or to the network. Normally it does not start off that way, normally it’s during an upgrade of some type. One day it’s not connected and the next day it is.”
“It is a good question for commanders to be asking themselves: Hey, are our systems connected? Are they somehow connected to the Internet? Have we had any recent upgrades that made these things smart, like smart weapon, where it can transmit data to and from other places?”
“And it’s probably a question they are not very comfortable asking themselves,” he added.
Meanwhile a former MI5 agent and whistleblower, Annie Machon, noted the reports of unauthorized access to US-made military systems “is a parallel with some of the disclosures that Edward Snowden has come out with.”
“The US based software is often very closed, very proprietary, nobody is allowed to see what their codes contain and the NSA has lent on companies to make sure that back doors are built in, which is for NSA to look at and its vassal states,” Machon told RT, talking on the vulnerabilities of the military hardware, governed by American software.
Last month, Germany announced that it planned to replace Patriot missiles with MEADS (Medium Extended Air Defense System), a new air defense system developed by the USA, Italy and Germany. The cost of the move is estimated at more than €4 billion.
“Who actually has their finger on the trigger? This is a basic problem for partners of the US. If they buy US software, if they buy US military hardware, do they really have control of it?” Machon wondered.
“Now, any country that is serious about its national security, its national interests should surely be building its own weaponry. And it should be making sure it’s developing its own population knowledge base, its skills base – to be able to do that, too.”

How Computer Manufacturers Are Paid to Make Your Laptop Worse
A laptop is a marvel of engineering. So much work goes into designing and manufacturing all the individual pieces of hardware before combining them with software that’s taken decades to build. After going through all this work, laptop manufacturers are paid to make their laptops slower and more frustrating to use.
The PC ecosystem’s race to the bottom and cut-throat pricing means that many computer manufacturers aren’t focused on providing a good experience — they’re focused on releasing the cheapest laptops possible and making some additional money by loading the laptop with bloatware.
The Bloatware Is There Because It PaysYour laptop’s manufacturer doesn’t really believe Norton antivirus is the best security solution, or that some obscure casual game portal has the best games available for Windows. Instead, they’re paid by software companies to preinstall this stuff.
Instead, laptop manufacturers load their computers up with shovelware — so-named because it seems as if manufacturers just shovel a pile of software onto the computer without much thought given to is usefulness. This often-useless software slows a laptop down, making it take longer to boot, reducing available memory, and generally cluttering up the computer. Toolbars may insert themselves into browsers and pop-up messages may urge the user to upgrade to paid copies of trial software. Messages for trial antivirus programs can be particularly scary, warning users they may be at risk if they don’t open their wallets and pay additional money.
These programs are generally trial versions that urge you to purchase paid software, links to places where you can purchase software, or browser toolbars that encourage you to use bad search engines. Software companies pay the manufacturers so inexperienced users will end up purchasing complete versions of the trial software, paying for bad casual games, and using less-useful search engines.
How Much Does Bloatware Slow a Laptop Down, Really?Do we geeks exaggerate the significance of bloatware on a laptop? Benchmarks would help us understand just how significantly bloatware can drag down a new computer.
Luckily, such benchmarks exist. They even come from an unlikely source — Microsoft. Microsoft sells “Microsoft signature” PCs in its Microsoft stores, which are laptops free of the usual manufacturer-installed crapware. Microsoft even offers to turn any laptop into a Signature laptop, getting rid of the bloatware for you –for only $99. Microsoft is making money coming and going here — you pay them for a Windows license that comes with your computer and then you pay them more than the cost of a Windows license so your new laptop will work like it should.
Microsoft advertises their signature PCs by pointing out how much faster a signature PC is than a non-signature PC — these statistics really tell us how much faster a new laptop is once all the bloatware is removed. They’ve now removed the statistics from their latest Signature PC page — maybe they were a bit embarrassing to Microsoft’s hardware partners — but we can view them with archive.org.
Based on Microsoft’s tests with six different Windows 7 laptops, removing bloatware made the laptops start up nearly 40% faster on average. That’s a significant improvement that shows us just how much bloatware can affect performance.
Worse yet, a 2009 PC Pro study found that bloatware could add over a minute to boot-up times, with Acer’s laptops taking an additional two minutes to boot because of all the included bloatware.
Banishing BloatwareIf you have a new laptop packed full of bloatware but don’t want to pay Microsoft $99 for the privelage of getting rid of it, you have some options:
Manually Uninstall Bloatware: You can uninstall bloatware that comes with your laptop from the standard Uninstall Programs pane in the Windows Control Panel. You’ll need to know the programs you should uninstall and the ones you should keep. Some utilities may help you take full advantage of your laptop’s hardware, while some are completely useless. Preinstalled bloatware will vary wildly from laptop to laptop — if you perform some Google searches, you should be able to find an explanation of what each program does. You may even find a a full, user-created guide to the bloatware that comes on your specific laptop, what it does, and which programs you should remove.
Automatically Uninstall Bloatware: If you don’t want to do all of the grunt work yourself, try using the free PC Decrapifier program. It will scan your computer for known bloatware and automatically uninstall it. However, PC Decrapifier isn’t perfect and it won’t catch all the bloatware.
Reinstall Windows: Many geeks prefer to install a clean copy of Windows on their new PCs, removing all the manufacturer software and starting with a clean slate. If you opt to do this, you’ll need a Windows disc. You’ll also need to download and install the appropriate drivers and hardware utilities for your laptop afterwards — you can generally find them on the manufacturer’s support site for your laptop.
If you’ve ever purchased a new laptop and found yourself spending minutes watching the bloatware load every time you power on your laptop, you can probably understand why so many people buy Macs.
We geeks may know how to deal with bloatware, but the average computer buyer is getting stuck with a laptop made worse by its manufacturer.
