Comments Off on Did Hackers Attack Water System?
Federal investigators are investigating a report that hackers managed to remotely shut down a utility’s water pump in central Illinois last week, in what could be the first known foreign cyber attack on a U.S. industrial system.
The November 8 incident was described in a one-page report from the Illinois Statewide Terrorism and Intelligence Center, according to Joe Weiss, a prominent expert on protecting infrastructure from cyber attacks.
The attackers obtained access to the network of a water utility in a rural community west of the state capital Springfield with credentials stolen from a company that makes software used to control industrial systems, according to the account obtained by Weiss. It did not explain the motive of the attackers.
He said that the same group may have attacked other industrial targets or be planning strikes using credentials stolen from the same software maker.
The U.S. Department of Homeland Security and the Federal Bureau of Investigation are examining the matter, said DHS spokesman Peter Boogaard.

Comments Off on at&t iPhone 4S Has Fastest Speeds
A study measuring the performance of the iPhone 4S on the three major U.S. wireless carriers found AT&T to be the best in Web browsing and data downloads and uploads when compared to Apple’s latest smartphone on either the Verizon Wireless or Sprint networks.
iPhone newcomer Sprint was found to be superior with its iPhone 4S for network voice quality on the uplink (when the user is speaking), but Sprint was also about five times slower in Web browsing and data downloads than AT&T, according to the study released Friday by Metrico Wireless, a mobile performance measurement company. Verizon finished in the middle on those data tests, but trailed the other two carriers in voice quality.
Metrico measured five performance factors shortly after the iPhone 4S was launched on all three carriers in October: whether calls could be connected and held; voice quality; data performance; Web browsing by page load speeds and video performance.

Apple’s Patent Hints At Tablet-Macbook Hybrid
Comments Off on Apple’s Patent Hints At Tablet-Macbook Hybrid
Apple has received approval from the U.S. Patent Office this week for a patent for a MacBook with a cellular antenna and a rotating display. Such a MacBook could have the super thin qualities of the MacBook Air and the cellular connectivity and touchscreen versatility of the iPad.
It could also strengthen Apple against the onslaught of Ultrabooks that PC makers are gearing up to unleash. “This officially announces to the Wintel camp that Apple now has the ability to match or beat the Ultrabook design that is to come to market in 2013 with the [Intel] Haswell processor,” declared Jack Purcher, of Patently Apple.
Intel announced the Ultrabook category of PC laptops in May. The line is squarely aimed at the MacBook Air. The first wave of Ultrabooks, based on existing Intel processors, has already begun to hit the market. The units are supposed to be priced under $1000 and be super thin–0.78 inches–or in the case of the HP Folio announced today, even less–0.70 inches.
Next year, the platform is expected to be advanced further with the introduction of units based on Intel’s Ivy Bridge processor. A third wave of Ultrabooks is planned for 2013. They would be based on the Haswell processor and consume half the power of today’s laptops. Some of them also will sport Windows 8 with its touchscreen-enabled Metro interface.
Intel Gives Details On Their Xeon E5 Processors
Comments Off on Intel Gives Details On Their Xeon E5 Processors
Intel finally gave more details at the supercomputing conference SC2011 about its upcoming Xeon E5 processors and been showing off its Knights Corner many integrated core (MIC) solution.
We don’t expect to see the new Xeons until the first half of 2012, but Intel has has been shipping the new chips to “a small number of cloud and HPC customers” since September. The E5 family has the same core as the 3960X which Intel launched this week. So far though Intel does not seem to be keen to ramp up any mass production. Some of this might have something to do with problems in production which were rumoured earlier this year. However early benchmarks indicate that it could be a winner.

Qualcomm Releases New S4 Processors
Comments Off on Qualcomm Releases New S4 Processors
Qualcomm has announced a slew of Krait-based Snapdragon system-on-chips (SoC) processors to fit in its S1 and S4 performance classes.
Qualcomm’s Snapdragon range of SoC chips have proven to be extremely popular in smartphones and tablets, however the firm is facing a growing challenge from Texas Instruments and Nvidia. Coming little over a week after Nvidia revealed its quad-core Tegra 3 processor, Qualcomm has announced eight Snapdragon S4 processors and four Snapdragon S1 processors.
Since Qualcomm showed off the Krait architecture in February with three chips, the firm has not extended its headline S4 range of processors. Now it has added eight SKUs, with models including the MSM8660A, MSM8260A, MSM8630, MSM8230, MSM8627, MSM8227, APQ8060A and APQ8030. Qualcomm was cagey about when devices sporting these chips will appear, only mentioning an early 2012 timeframe.
Perhaps more important for Qualcomm’s sales figures are its entry level Snapdragon S1 chips. The four new chips in this category are the MSM7225A, MSM7625A, MSM7227A and MSM7627A models, with the firm claiming that they have been optimised for those OEM customers that are making the transition from 2G to 3G devices.
Apple Has A Hole In MAC OS X
Apple has failed to fix a bug in its Mac OS X operating system that allows processes to bypass the sandbox protection in place.
The flaw was discovered by Anibal Sacco and Matias Eissler from Core Security Technologies. They let Apple know about the problem on 20 September, and while Apple acknowledged their submission, it said that it did not see any security threat, forcing the Core Security Technologies team to publish the report to the public this month.
The problem appears to be with the use of Apple events in several default profiles, including the no-network and no-internet ones. When Apple events are dispatched a process can escape the sandbox, which could be exploited by hackers.
The vulnerability could lead to a compromised application restricted by the use of the no-network profile gaining access to network resources through the use of Apple events to execute other applications that are not restricted by the sandbox, making it a significant security threat.
Only the more recent versions of Mac OS X are vulnerable to this bug, including 10.5.x, 10.6.x, and 10.7.x. Those using 10.4.x are safe from the exploit.
DoJ Charges Clickjacking Perpetrators
Comments Off on DoJ Charges Clickjacking Perpetrators
The U.S. Department of Justice is charging seven individuals with 27 counts of wire fraud and other computer-related crimes, accusing the group of hijacking 4 million computers across 100 countries in a sophisticated clickjacking scam.
According to the indictment, the defendants had set up a fake Internet advertising agency, entering into agreements with online ad providers that would pay the group whenever its ads where clicked on by users. The group’s malware, which it had planted on millions of user computers, would redirect the computers’ browsers to its advertisements, thereby generating illicit revenue.
The malware worked by capturing and altering the results of a user’s search engine query. A user would search for a popular site, such as ones for Netflix, the Wall Street Journal, Amazon, Apple iTunes and the U.S. Internal Revenue Service. Whenever the user would click on the provided link, however, the browser would be redirected to another website, one that the group was paid to generate traffic for.
The malware the group used also blocked antivirus software updates, which left users vulnerable to other attacks as well, according to the DOJ.

Google, which last week created a bit of chaos with the launch of a Gmail application for Apple iOS devices, has decided to put out discontinue its Gmail application for the BlackBerry.
As of Nov. 22, Google will no longer offer technical support to users of the application, nor will it allow people to download it anymore, the company wrote in a blog post.
However, people will be able to continue using it, although Google will put its development efforts on the version of the application for mobile browsers, available at gmail.com.
Comcast Starts IPv6 Network Rollout
Comcast has begun the production rollout of its new IPv6 service, with 100 customers upgraded in San Francisco’s East Bay in one week.
IPv6 is an upgrade to the Internet’s main communications protocol, which is called IPv4. IPv6 features an expanded addressing scheme that can support billions of devices connected directly to the Internet at faster speeds and lower cost than IPv4, which is running out of addresses.
Comcast began an IPv6 trial 18 months ago and is a leader in the deployment of IPv6-based services among U.S. ISPs.
The production rollout began on Oct. 31. It offers customers “native dual-stack service,” which means Comcast is supporting both IPv6 and IPv4 services.
The initial subscribers of Comcast’s production-quality IPv6 service have stand-alone computers running Microsoft Windows 7, Windows Vista or Apple Mac OS X that are connected directly to a Comcast cable modem. Comcast plans to support IPv6 for customers with home routers at a later date.
White House Threatens Net Veto
The executive office of U.S. President Barack Obama stated Tuesday that the White House strongly opposes passage in the Senate of a resolution that could impact the equal availability of the Internet to all classes of users.
The resolution introduced in the Senate disapproves a rule submitted by the Federal Communications Commission in December on the net neutrality issue, and states that it should have “no force or effect”.
If the President is presented with the resolution, S.J. Res. 6, which would not safeguard the free and open Internet, his senior advisers would recommend that he veto it, the administration said.
The FCC Report and Order adopted the rule that fixed broadband providers may not unreasonably discriminate in transmitting lawful network traffic”. A “no blocking” rule states that fixed broadband providers may not block lawful content, applications, services, or non-harmful devices. Mobile broadband providers are also prohibited from blocking lawful websites, or block applications that compete with their voice or video telephony services.
The U.S. House of Representatives has already passed in April a Republican-backed resolution disapproving the FCC rules, and asking for their roll back.
