Black Friday iTunes malware alert

Criminals are targeting internet users with a new gift certificate scam, according to security experts.

Users receive an email that claims to be from Apple's iTunes store, warns the Eleven security blog.

The ZIP file attached contains malware that may allow hackers to gain access to the recipient's computer.

The blog says the attack appears to have been timed to coincide with Black Friday, one of the US's busiest shopping days.

Black Friday was the name used by Philadelphia's police department in the 1960s to describe the day after Thanksgiving because of all the traffic jams caused by people visiting the city's stores.

It is now viewed by many retailers as the start of the Christmas shopping season. They mark the day with one-off discounts and other special offers.

Eleven says the period has become one of the most popular times for internet scammers to target users.

Infected offer

The security firm says that users are told they have been sent $50 (�32) of iTunes store credit and need to open an attached file to find out their certificate code.

The file contains a program known as Mal/BredoZp-B.

PCthreat.com says the software opens up a backdoor on the users' computers and may also capture passwords and other information.

It says the code may also slow down the infected computer's performance and make files disappear.

The malware can be removed with the use of anti-spyware tools.

Facebook phishing

Security adviser Sophos warns of a separate threat linked to Facebook.

It says users are receiving emails claiming that they have violated the social network's policy regulations by annoying or insulting other members.

An attached link take users to a web page that presents them with a fake "Facebook Account Disabled" form.

The firm says that members are then asked to fill in a series of forms requesting their login details, country of residence and the first six digits of their credit card number.

If the users refuse they are told their account will be blocked automatically.

"New day, new attempt," writes Sophos's security writer Lisa Vaas on the company's blog.

"All these phishing scams boil down to a naked grab for your account details. Remember, neither Facebook nor other reputable social media sites would ask for this information."

Cyborg insect power breakthrough

Efforts to create an army of cyborg insects are being pursued by a team of US-based engineers.

The group is investigating ways to harvest energy from the creatures to power sensors and other equipment fastened to their bodies.

The team has created an energy scavenging device that is attached close to the insects' wings.

It suggested the creatures might one day be used to aid search-and-rescue operations and surveillance.

The University of Michigan team of engineers published their study in the Journal of Micromechanics and Microengineering.

Power source

The report noted that, despite major advances in micro-air-vehicle technology, no-one had been able to match the aerodynamic performance and manoeuvring capability of insects.

However, it said that if insects were to be equipped with control mechanisms and other add-on kit, the equipment would require a power source.

The team rejected the idea of using miniature solar panels because they would be dependent on available light. So the group decided to develop a vibration energy collector.

The resulting device consists of a tiny three-layered spiral generator.

The outer two layers are made up of PZT-5H - a ceramic substance that produces an electrical charge when mechanical stress is applied. An inner layer of brass provides reinforcement.

Muscle power

The researchers used Green June Beetles to determine the best place to locate the device.

They identified the wings as the most promising power source.

However, the creatures' wing membranes were not rigid or strong enough to support the device, and it also made them less aerodynamic. So the team focussed, instead, on the animals' wing muscle.

The engineers ultimately decided to attach two of the spiral beams to each beetle's thorax. The end of each coil extended out to touch a hardened part of the insect's body close to its wing base where it could pick up energy.

The two devices weighed less than 0.2 grams and generated 45 microwatts of power during flight.

Cyborgs

The researchers suggested that the devices could eventually become the power source for a race of remote controlled cyborg insects with neural electrodes implants, communications equipment, microphones and other sensors.

The team suggested the creatures could wear the equipment in tiny "backpacks".

The animals could then be released into dangerous or hard-to-access locations after an accident has occurred. The information they gathered could be beamed back to the emergency services to help prepare a response.

They said the creatures could usher in "a new era for search-and-rescue operations, surveillance, monitoring of hazardous substances, and detection of explosives".

This is not the first time researchers have tried to work out how to turn animals into remote-controlled automatons.

The report's authors noted experiments to control rats through the parts of their brains related to their whiskers, an attempt to direct sharks by stimulating the part of their brain linked to their sense of smell and research into the locomotion control of cockroaches.

The team also noted that a previous attempt to harvest vibration energy from moths had failed because the 1.28g weight of the device involved proved too heavy for the insects to carry.

Google, Samsung confirm Nexus bug

Google and Samsung have confirmed that there are volume issues with their flagship mobile phone the Galaxy Nexus.

It follows complaints on net forums about unexplained changes in volume.

The handset, the first to feature Google's operating system Android Ice Cream Sandwich, is currently available in the UK and is due to go on sale in the US in December.

Samsung said that it is aware of the problem and will offer a repair but did not say when.

"Regarding the Galaxy Nexus, we are aware of the volume issue and have developed a fix," Samsung said in a statement. "We will update devices as soon as possible."

Google issued an almost identical statement.

Silent alarm

Posting on Google's Android user forum Damian M summed up the problem many seem to be experiencing: "Volume drops to nothing seemingly at random, volume rocker becomes unresponsive for a few seconds," he said.

Some users reported that the issues became worse when using the 2G network. Others complained that they were unable to rely on the device.

"Had this problem since buying the phone on the 17 Nov. Happened so far on 3G, wifi and using the sat nav. It also happened this morning again when my alarm went off," wrote one user nicknamed Stuartea.

"I was already awake and had not touched the phone yet, the alarm sounded for a second and then went silent. Thought that was weird so checked the phone and the volume was down. I can't trust the alarm to wake me up now for work!"

It is unclear at this stage whether the issues are caused by hardware or software faults.

Rivalry

The problem comes as Apple rushes to fix a bug in its new operating system iOS 5.

Users complain that iPhone batteries are running down too quickly.

An initial software patch issued by Apple to solve the problem has not appeared to have helped.

Apple and Samsung are engaged in a fierce rivalry for market share.

Research from Strategy Analytics suggested that Samsung had overtaken Apple to become the world's biggest shipper of smartphones between July and September.

The study said that the South Korean firm had shipped 27.8 million smartphones in the three-month period, compared with 17.1 million from Apple and 16.8 million from Nokia.

Meanwhile, Samsung and Apple remain locked in intellectual property disputes around the world. Both are trying to ban sales of each other's products.

HTC shares plunge on growth cut

Shares of smartphone maker HTC have fallen by 7%, the maximum allowed in one day, after the company cut its growth forecast.

Taiwan-based HTC said on Wednesday that it expected revenues for the final three months of 2011 to be little changed from a year earlier.

The firm had earlier forecast growth of 20% to 30%.

HTC, the world's fourth-biggest smartphone brand, blamed increased competition and weakening demand.

Analysts and the markets were surprised by the statement filed with the Taiwan Stock Exchange.

"This new guidance takes us by complete surprise and is at odds with recent discussions we have had with distribution channels, especially in Europe," said Sanford Bernstein from Pierre Ferragu in a note to clients.

In October, the company had warned that fourth quarter revenue was slowing, predicting 125bn to 135bn New Taiwan dollars ($4.1bn-$4.4bn; �2.6bn-$2.9bn), compared with T$135.8bn in the previous three months.

Although HTC did not give a specific forecast for Wednesday's further downward revision, it said it predicted no growth compared to the same period last year. HTC's revenue in the last three months of 2010 was T$104bn.

Analysts said the grim outlook could be blamed on lack of new products to compete with an expansion in Apple's distribution channels in the US.

However, the company said it expected a pick up in revenue in the first half of 2012.

Firms 'not ready for IT failure'

Almost three-quarters of firms and public sector organisations across nine European countries may not fully recover their computer systems or data after an IT failure, a survey suggests.

The report by IT group EMC said 74% were "not very confident" they could fully restore their networks.

It also found that 54% admitted they had lost data or suffered systems downtime in the past 12 months.

A total 1,750 IT bosses in countries including the UK were questioned.

The other countries covered in the survey were Germany, France, Italy, Spain, Belgium, Netherlands, Luxembourg and Russia.

EMC said firms needed to put more focus on backup and recovery systems.

Its report found that the most common cause of data loss and downtime was hardware failure, followed by power outage and software malfunction.
