‘Stegano’ Malvertising Exposes Millions To Hacking

Comments Off on ‘Stegano’ Malvertising Exposes Millions To Hacking

Since October, millions of internet users have been exposed to malicious code embedded in the pixels from tainted banner ads designed to install Trojans and spyware, according to security firm ESET.

The attack campaign, called Stegano, has been spreading from malicious ads in a “number of reputable news websites,” ESET said in a Tuesday blog post. It’s been preying on Internet Explorer users by scanning for vulnerabilities in Adobe Flash and then exploiting them.

The attack is designed to infect victims with malware that can steal email password credentials through its keylogging and screenshot grabbing features, among others.

The attack is also hard to detect. To infect their victims, the hackers were essentially poisoning the pixels used in the tainted banner ads, ESET said in a separate post.

The hackers concealed their malicious coding in the parameters controlling the pixels’ transparency on the banner ad. This allowed their attack to go unnoticed by the legitimate advertising networks.

Victims will typically see a banner ad for a product called “Browser Defense” or “Broxu.” But in reality, the ad is also designed to run Javascript that will secretly open a new browser window to a malicious website designed to exploit vulnerabilities in Flash that will help carry out the rest of the attack.

Hackers have used similar so-called malvertising tactics to secretly serve malicious coding over legitimate online advertising networks. It’s an attack method that has proven to be a successful at quickly spreading malware to potentially millions.

The makers behind the Stegano attack were also careful to create safeguards to prevent detection, ESET said. For instance, the banner ads will alternate between serving a malicious version or a clean version, depending on the settings run on the victim’s computer. It will also check for any security products or virtualization software on the machine before proceeding with the attack.

ESET declined to name the news websites that were found unknowingly displaying the malicious ads, but cautioned that the attack was widespread, and could have been hosted through other popular sites as well.

Can iOS Activation Lock Be Bypassed?

Comments Off on Can iOS Activation Lock Be Bypassed?

Two researchers report that they have discovered a way to bypass the activation lock feature in iOS that’s supposed to prevent anyone from using an iPhone or iPad marked as lost by its owner.

The first report came Sunday from an Indian security researcher named Hemanth Joseph, who started investigating possible bypasses after being confronted with a locked iPad he acquired from eBay.

The activation lock gets enabled automatically when users turn on the Find My iPhone feature via iCloud. It links the device to their Apple IDs and prevents anyone else from accessing the device without entering the associated password.

One of the few things allowed from the activation lock screen is connecting the device to a Wi-Fi network, including manually configuring one. Hemanth had the idea of trying to crash the service that enforces the lock screen by entering very long strings of characters in the WPA2-Enterprise username and password fields.

The researcher claims that, after awhile, the screen froze, and he used the iPad smart cover sold by Apple to put the tablet to sleep and then reopen it. This is supposed to restore the state of the tablet from where it was left off, in this case, loading the WPA2 screen again with the long strings of characters filled in.

“After 20-25 seconds the Add Wifi Connection screen crashed to the iPad home screen, thereby bypassing the so-called Find My iPhone Activation Lock,” he said in a blog post.

Hemanth said he reported the issue to Apple on Nov. 4, and the company is investigating it. He tested the bypass on iOS 10.1, which was released on Oct. 24.

Last week, a researcher named Benjamin Kunz Mejri, from German outfit Vulnerability Lab, posted a video showing the same bypass, but on the newer iOS 10.1.1 version.

Kunz Mejri’s method is similar and also involves overflowing the Add Wi-Fi form fields with long strings of characters but also requires rotating the tablet’s screen in order to trigger the crash after the smart cover trick.

Apple has not yet confirmed that issue and did not immediately respond to a request for comment.

PC Market Showing Signs Of Life

Comments Off on PC Market Showing Signs Of Life

The PC market is showing some signs of growth, with Intel boosting its revenue guidance based on improved chip shipments.

The chip maker has raised its revenue guidance for the third quarter to $15.6 billion, plus or minus $300 million, an improvement from $14.9 million, plus or minus $500 million.

That’s due to PC makers replenishing laptop and desktop inventory, which means Intel is shipping out more chips. It’s likely in anticipation of the holiday season, when PC shipments rocket.

“The company is also seeing some signs of improving PC demand,” Intel said in a statement.

In the second quarter of the year, PC makers slowed down chip orders and were clearing out existing stock of laptops and desktops. PC shipments declined by 4.5 percent during that period, according to IDC.

Shipments of gaming PCs, 2-in-1s and Chromebooks are driving PC shipments. Microsoft’s free upgrade offer to Windows 10 has also ended, which means users are more likely to buy new PCs to get Windows 10.

Meanwhile, new laptops with Intel’s Kaby Lake chips are now available. All the top PC makers have announced new 2-in-1s and laptops with Intel’s new chips. New Kaby Lake chips for gaming PCs will be announced in January.

Intel also has started shipping Pentium and Celeron chips, both aimed at low-cost laptops, based on the same architecture and code-named Apollo Lake. Many Chromebooks are based on Apollo Lake chips.

Google And Yahoo Get Blocked

Comments Off on Google And Yahoo Get Blocked

The IT department of the U.S. House of Representatives is prohibiting access to Yahoo Mail and the Google App Engine platform due to malware threats.

On April 30, the House’s Technology Service Desk informed users about an increase in ransomware-related emails on third-party email services like Yahoo Mail and Gmail.

“The House Information Security Office is taking a number of steps to address this specific attack,” the Technology Service Desk said in an email obtained and published by Gizmodo. “As part of that effort, we will be blocking access to Yahoo Mail on the House Network until further notice.”

The ban on Yahoo Mail access suggests that some House of Representatives workers accessed Yahoo mailboxes from their work computers. This raises questions: Are House workers using Yahoo Mail for official business, and, if they’re not, are they allowed to check their private email accounts on work devices?

If they use the same devices for both personal and work activities, one would hope that there are access controls in place to separate the work and personal data. Otherwise, if they are allowed to take those devices outside of the House’s network, they could just as easily become infected there, where the ban is not in effect.

“The recent attacks have focused on using .js files attached as ZIP files to e-mail that appear to come from known senders,” the House’s Technology Service Desk said. “The primary focus appears to be through Yahoo Mail at this time.”

The increase in ZIP and RAR attachments that contain malicious JavaScript (JS) files has been observed by multiple security companies in recent months. Microsoft offers several recommendations, like using the Windows AppLocker group policy to restrict the execution of .JS files.

The House Information Security Office also banned access to appspot.com, the domain name used by applications hosted on the Google App Engine platform, Reuters reported.

Are Tablets Dead?

Comments Off on Are Tablets Dead?

There more evidence that tablets were never the game-changer that Steve Jobs tried to peddle them as, and were just the keyboardless netbooks we said they were.

IDC siad that for the first quarter of 2016, overall worldwide tablet shipments fell to 39.6 million, a 14.7 percent drop from the same period a year ago,  However the only part of the segment which did ok were tablets with keyboards – or as we used to call them, netbooks.

IDC said that the decline of ordinary tablets was partly due to traditional first-quarter slumps but also a complete lack of interest on the part of customers.

Traditional tablets accounted for 87.6 percent of all tablet shipments. But tablets that come with detachable keyboards increased of more than 4.9 million units last quarter. That was a gain of 120 percent from the same period last year and an all-time high for tablets with detachable keyboards.

Tablets are dying because more people are buying big-screened phones as an alternative. You remember Fablets? They were what Steve Jobs claimed would never work because they prefered smaller smartphones or bigger tablets. In fact he was talking rubbish and was trying to keep his keyboardless netbook idea going.

IDC said that the newer tablets don’t offer enough new features to entice people to upgrade. After all tablets were always looking for an app which made them useful, which never arrived.

To counteract the downturn, more manufacturers are turning to tablets with detachable keyboards that can thus serve as laptops – on otherwords returning to the netbooks that the Tablets were said to replace.

“With the PC industry in decline, the detachable market stands to benefit as consumers and enterprises seek to replace their aging PCs with detachables,” IDC senior research analyst Jitesh Ubrani said in a statement.

Apple saw its shipments and market share drop but remained in first place. Apple’s latest 9.7-inch iPad Pro and the new 256GB storage option for the 12.9-inch iPad Pro are “healthy additions” to the lineup, IDC said. Samsung also saw its shipments and market share decline. Though the Samsung Galaxy Tab lineup is still popular, its detachable TabPro S is dead in the water thanks to its $900 price tag.

Amazon has found success with its starting-at-$49 Fire, showing that consumers will still buy bargain-priced tablets. Missing from the list was Microsoft in spite of the popularity of its Surface Pro products, which start at $900.

IDC said:

“The Surface line is great. But it’s tough to drive volume in the first quarter. Prices of Surface products are fairly high, but Microsoft is in the top five list for tablets with detachable keyboards. The top five for tablets as a whole is a tougher nut to crack given the large slate volumes compared to detachables.”

Intel Opens Up Core M

Comments Off on Intel Opens Up Core M

Intel has extended its Core M range of fanless mobile chips by adding four models to the three initial Core M processors launched at the IFA trade show in September.

Like those first fanless models, Intel’s new Core M processors are dual-core chips that support Hyperthreading in up to four threads and have thermal design power (TDP) ratings of 4.5W.

They’re faster than the initial Core M chips, with base clock speeds ranging from 800MHz to 1.2GHz and Turbo Boost speeds from 2GHz to 2.9GHz.

The firm’s initial Core M chips were also rated at 4.5W TDP but topped out at 1.1GHz and 2.6GHz under Turbo Boost.

These additional fanless mobile chips are configurable by system designers, in that OEMs can scale the chip speeds and power consumption up or down depending on the purpose and configuration of the device.

A compact tablet or notebook can conserve power by limiting processor speed, while a larger device can offer higher speed at the cost of higher power draw and heat.

Thus, these new Core M chips can be configured from 600MHz base clock speed and 3.5W TDP to 1.4GHz base clock speed and 6W TDP in the fastest model.

Intel has also boosted the integrated graphics processors in these latest Core M chips, offering GPU base clock speeds ranging from 300MHz to 900MHz, whereas the initial models supported 100MHz to 850MHz.

The detailed specifications of all of Intel’s Core M mobile processors are available on the firm’s website.

Intel said that these new fanless Core M processors will start hitting the market early next year.

Intel Debuts A Slew Of Core M Chips

Comments Off on Intel Debuts A Slew Of Core M Chips

Intel’s new Core M chips — which bring PC-like performance to slim design tablets — will initially be in many Windows 8.1 tablets, but no Android devices are yet on the radar.

The chips will be in five to seven detachable tablets and hybrids by year end, and the number of devices could balloon to 20 next year, said Andy Cummins, mobile platform marketing manager at Intel.

Core M chips, announced at the IFA trade show in Berlin on Friday, are the first based on the new Broadwell architecture. The processors will pave the way for a new class of thin, large-screen tablets with long battery life, and also crank up performance to run full PC applications, Intel executives said in interviews.

“It’s about getting PC-type performance in this small design,” Cummins said. “[Core M] is much more optimized for thin, fanless systems.”

Tablets with Core M could be priced as low as US$699, but the initial batch of detachable tablets introduced at IFA are priced much higher. Lenovo’s 11.6-inch ThinkPad Helix 2 starts at $999, Dell’s 13.3-inch Latitude 13 7000 starts at $1,199, and Hewlett-Packard’s 13.3-inch Envy X2 starts at $1,049.99. The products are expected to ship in September or October.

Core M was also shown in paper-thin prototype tablets running Windows and Android at the Computex trade show in June. PC makers have not expressed interest in building Android tablets with Core M, but the OS can be adapted for the chips, Cummins said.

The dual-core chips draw as little as 4.5 watts, making it the lowest-power Core processor ever made by Intel. The clock speeds start at 800MHz when running in tablet mode, and scales up to 2.6GHz when running PC applications.

The power and performance characteristics make Core M relevant primarily for tablets. The chips are not designed for use in full-fledged PCs, Cummins said.

“If you are interested in the highest-performing parts, Core M probably isn’t the exact right choice. But if you are interested in that mix of tablet form factor, detachable/superthin form factor, this is where the Core M comes into play,” Cummins said.

For full-fledged laptops, users could opt for the upcoming fifth-generation Core processor, also based on Broadwell, Cummins said. Those chips are faster and will draw 15 watts of power or more, and be in laptops and desktops early next year.

New features in Core M curbed power consumption, and Intel is claiming performance gains compared to chips based on the older Haswell architecture. Tablets could offer around two more hours of battery life with Core M.
