Darwin flaw found in iOS

Published

on

Kaspersky Lab has discovered a vulnerability in the Darwin kernel of the Apple operating system that if exploited, leaves OS X and iOS 8 devices exposed to the remote activation of denial of service attacks on the devices.

Kaspersky Lab security researchers have discovered a vulnerability in the kernel of Darwin – an open-source component of both the OS X and iOS operating systems. This “Darwin Nuke” vulnerability leaves OS X 10.10 and iOS 8 devices exposed to remotely-activated denial of service (DoS) attacks that can damage the user’s device and impact any corporate network to which it is connected. The experts call on users to update devices with the OS X 10.10.3 and iOS 8.3 software releases, which no longer include this vulnerability.

Analysis of the vulnerability by Kaspersky Lab revealed that the devices affected by the threat include those with 64-bit processors and iOS 8: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad Air 2, iPad mini 2, and iPad mini 3.

The “Darwin Nuke” vulnerability is exploited while processing an IP packet of specific size and with invalid IP options. Remote attackers can initiate a DoS (denial of service) attack on a device with OS X 10.10 or iOS 8, sending an incorrect network packet to the target.  After processing the invalid network packet, the system will crash. Kaspersky Lab’s researchers discovered that the system will crash only if the IP packet meets the following conditions:

–          The size of the IP header should be 60 bytes.

–          The size of the IP payload should be less than or equal to 65 bytes.

–          The IP options should be incorrect (invalid option size, class, etc.)

“At first sight, it is very hard to exploit this bug, as the conditions attackers need to meet are not trivial ones. However persistent cybercriminals can do so, breaking down devices or even affecting the activity of corporate networks. Routers and firewalls would usually drop incorrect packets with invalid option sizes, but we discovered several combinations of incorrect IP options that are able to pass through the Internet routers. We’d like to encourage all OS X 10.10 and iOS 8 users to update devices to OS X 10.10.3 and iOS 8.3 releases,” – says Anton Ivanov, Senior Malware Analyst at Kaspersky Lab.

Kaspersky Lab’s products protect OS X against the “Darwin Nuke” vulnerability with the Network Attack Blocker feature. Starting with Kaspersky Internet Security for Mac 15.0, this threat is detected as DoS.OSX.Yosemite.ICMP.Error.exploit.

Kaspersky Lab’s tips for boosting the security of Mac devices include:

1.      Use a web browser that has a solid track record of fixing security issues promptly.

2.      Run “Software Update” and patch the machine promptly when updates are available.

3.      Use a password manager to help cope with phishing attacks.

4.      Install a good security solution.

CES: And thanks for all the beer!

Last week, the Las Vegas expo showed off its fun side with state-of-the-art technologies for making and enjoying beer, writes BRYAN TURNER

Published

on

From craft beer-making machines to robots that pour beer, CES had more beer than usual in Las Vegas last week. And even free beer if you found the right stand. Stampede’s saloon-style booth offered beer to visitors who tried out its latest drones, virtual reality, and other gaming products. No beer tech, though.

Here are some of the beer technologies that stood out:

LG HomeBrew – Craft beer made at home

LG’s HomeBrew craft beer-making machine,  debuted at CES 2019, brings the brewing process home thanks to single-use capsules,  a self-cleaning feature, and an algorithm optimised for fermentation. 

Like a Nespresso coffee machine, the beer maker uses capsules, which contain malt, yeast, hop oil and flavouring. At the press of a button, LG HomeBrew automates the whole procedure from fermentation and carbonation to ageing. A companion app lets users check HomeBrew’s status at any time during the process, from their handsets.

The beer machine not only offers a simple way to make craft beer, but also enhances the quality of beer it makes. The fermentation algorithm intelligently controls the fermenting process with precise temperature and pressure control. It automatically sanitises itself, using nothing more than hot water, ensuring everything is hygienically clean for the next batch.

Designed with discerning beer lovers in mind, HomeBrew allows for in-home production of batches of more than 4 litres of beer in a variety of styles. The following five distinctive, flavoured beers are available now: 

  • Hoppy American IPA
  • Golden American Pale Ale
  • Full-bodied English Stout
  • Zesty Belgian-style Witbier
  • Dry Czech Pilsner

The only catch? It takes about two weeks to make, depending on the beer type.

“LG HomeBrew is the culmination of years of home appliance and water purification technologies that we’ve developed over the decades,” said Dan Song, president of LG Electronics Home Appliance & Air Solutions Company. “Homebrewing has grown at an explosive pace, but there are still many beer lovers who haven’t taken the jump because of the barriers to entry, like complexity, and these are the consumers we think will be attracted to LG HomeBrew.”

CES: Alienware gets Legend-ary

Published

on

At CES in Las Vegas last week, Dell’s Alienware released a family of high-end, thin, light, and affordable machines for both amateur and professional gamers – and a new identity.

Alienware marked CES 2019 as a brand milestone with the debut of a new design identity, Alienware Legend. It aims to set a new bar of excellence for what gamers want most – performance and function. Alienware says it evaluated multiple concepts and chose one that was the biggest and boldest departure from its current look.

Alienware Legend, says the company, stays true to the brand’s core design tenets, taking cues from its deep roots in sci-fi culture and its early industrial designs, to distinguish the brand from the rest of the industry. The new Legend design is optimised with cutting-edge thermal cooling technology to achieve and sustain overclocking power, improved AlienFX lighting, and ultra-thin screen borders. It also unveiled a new “three-knuckle hinge” design that reduces the overall dimension while creating a stronger assembly, all combining to yield a better gaming experience.

“We’re excited to come to this year’s CES with some truly groundbreaking products, next-gen software and strategic partnerships that will bring more people to experience PC gaming and advance the industry,” said Frank Azor, vice president and general manager of Alienware. “The legend design answers the call for more and better from our gaming community, and the new G Series laptops will make PC gaming even more accessible to those looking for high-performance gaming at a cost they can appreciate.”
