Huge China based computer ring broke into computers worldwide

For the past several years, there has been an active discussion among researches about the impact that a sustained attack on the computer infrastructure of developed countries could achieve. With modern infrastructures such as electricity, water, transport, finance, etc all being controlled through computational technologies, there is a persisting fear that all of this infrastructure is under threat from any clever band of cyber attackers. Modern military games incorporate threats by hackers who are affiliated to sovereign countries, and in many cases, it is claimed that developing the ability to bring down the computer networks of other countries is part of the game plan for offensive action. In the past, it has been feared that countries such as China and Russia have developed capabilities for offensive cyber-warfare.
Consider this case where a computer network, based in China, and dubbed as the 'GhostNet' by a team of Canadian researches turned up a huge network based on computers located in China; these computers were the initiators of hacking attempts that broke into computers all over the world; this probe was based on a need by the Dalai Lama office in India to ensure that its own computers were not infected (link to article):


In "Tracking GhostNet: Investigating a Cyber Espionage Network," issued over the weekend, the Canadian researchers say that the GhostNet comprises 1,295 infected computers in 103 countries, almost one third of them being "high-value targets, including ministries of foreign affairs, embassies, international organizations, news media, and NGOs."
The breaches tended to stem from a so-called social-engineering exploit, in which targets in the Tibetan community were sent an e-mail that appeared to be from the address campaigns@freetibet.org and that carried an attached Word document titled "Translation of Freedom Movement ID Book for Tibetans in Exile"--and that Word document was infected with the malicious code. The University of Cambridge report, "The snooping dragon: social-malware surveillance of the Tibetan movement," doesn't refrain from charging that the Chinese government was directing malware attacks: "(I)t was a targeted surveillance attack designed to collect actionable intelligence for use by the police and security services of a repressive state, with potentially fatal consequences for those exposed."


These incidents are also warnings to Governments about how their infrastructural systems are only as strong as their weakest links. One node in the system getting hacked can lead into other nodes also falling, and lead to a risk that the entire system is being compromised. In the current system, it was also found that the exploit had the powers to turn on the voice recording and the camera systems of the infected computer, leading to a spying of the proceedings happening in front of the computer.

Sony changes plan to charge for removing 'bloatware'

When you buy a new OEM machine, it comes with a lot of programs that are on trial, such as anti-virus software trial versions, and numerous other software. There are 2 advantages for the makers of these software as well as for the computer manufacturers. The software makers depend on a proportion of consumers becoming attracted enough towards these applications that they are willing to pay for buying these programs. Getting these softwares pre-installed on the machine helps expose them to a much higher number of consumers and increases the chances of conversion. For this advantage, these trial software makers pay computer manufacturers for the chance of placing their software on these machines. It is estimated that xomputer manufacturers can make more than $50 per machine from such software.
For a vast majority of the final consumers / buyers of the machine, these software consume hard disk space, as well as run all the time slowing the machine down. Most consumers will not know how to remove such software, and suffer. For an advanced user, the options include removing the programs one by one, or by doing a fresh install on the machine that will remove these software, called 'bloatware'. So, imagine the pleasure of consumers when Sony declared that it will give a machine that does not come pre-loaded with such software; then this pleasure turned to shock when they found out that Sony will charge them $49.99 for removing this bloatware. There was a strong reaction to such a move; imagine paying extra to have the manufacturer not loading extra stuff on the machine:


"Bloatware" is a term that is familiar to many new computer buyers. Most new computers come saddled with HDD and memory-robbing applications like trial versions of antivirus programs, various desktop search and chat applications, or perennial offenders like Adobe Acrobat. Computer makers rely on these add-on programs to generate additional revenue in the age of decreasing computer prices -- bloatware can add as much as $60 in additional revenue for each computer sold.
Sony, however, made the unwise decision to charge customers a $49.99 fee for the bloatware removal. Whether the charge was intended to somewhat makeup for the estimated $60 windfall from the application publishers or just an effort to squeeze more money from its customers remains to be seen. News of the $49.99 Fresh Start fee quickly spread around the Internet Saturday with sites taking Sony to task over the blunder. Sony quickly recoiled and removed the Fresh Start fee.


This quick reaction by consumers and Sony's quick acceptance of this customer outrage shows that corporations are quickly cottoning onto the fact that customers, especially in this age of quick communications can turn reactions against a company very fast. Sony last suffered such a bad reaction over their Rootkit fiasco, and the prolonged bad press at that time would have made them much nimbler this time.

Some of Microsoft's dealings with Intel and HP revealed

It is not often that the internal dealings of a company such as Microsoft are released to the public for analysis, especially when it deals with the interaction of the company with other major chip and computer manufacturers such as HP and Intel. But, a federal class-action lawsuit provides access to internal emails that are worrisome to customers who have bought machines labeled Vista capable; they can no longer be sure that the certification provided by Microsoft to such machines is genuine. Read this article and these excerpts to understand more:


But documents show that in early 2006, a full year before Vista's release, there was intense discord within Microsoft over its dealings with Intel, HP and others in preparing to roll out the new system. The documents suggest Microsoft bowed to Intel's pressure in certifying certain chips as capable of running the new operating system to enhance sales. Intel declined to comment on assertions that it had pressured Microsoft. "It's private litigation between plaintiffs and Microsoft, and we're not a party to it," Intel spokesman Chuck Mulloy said.
At issue is whether Microsoft misled customers by labeling PCs carrying the Intel 915 chipset as "Vista Capable" when they were put on sale in spring 2006, ahead of the much-anticipated launch of the Vista operating system. Only computers labeled "Premium Ready" carried the more advanced Intel 945 chip and could operate Vista's touted features, such as Aero graphics.


If all this is true, it is tantamount to deceiving computers. Customers buying computers do not have the technical competency to evaluate whether a particular chip and computer were capable of running Vista; if the certification says that the chip is capable, the customer would believe so.

HBO joins the online TV content fray

HBO, one of the last holdouts in the age of providing digital entertainment media online, has finally given up (or maybe acknowledged that it will lose out on a whole bunch of subscribers if it does not enter the race) and launched a service called HBO On Broadband that features 400 hours of both movies and serials that can be downloaded onto a computer. However, as of now, there are several restrictions, with these restrictions across computer platforms, and locations:


The catch: To gain access, you must be a digital cable customer who subscribes to HBO, and you must use your cable company as your Internet provider. And, at least initially, you must live in Milwaukee or Green Bay, where Time Warner Cable will first test the service. (There's no extra cost for online access.)
HBO Broadband offers a broad selection of programming, including 130 movie titles that rotate monthly and top hits ranging from The Sopranos to Sex and the City, as well as documentaries. Usually, about six episodes will be offered at any one time, but for one series every month, every episode ever produced will be available. HBO co-president Eric Kessler blames technological issues for the delay in offering online video but says the new service continues the network's plan to "enhance the value of the HBO subscription by giving viewers greater access to our content."


This is almost like testing the waters, and one can forecast that geographical locations will get added, and so will more controls to prevent piracy. And right now this service is free, but one can be sure that at some point, HBO will want to make money with this.
