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.

Meet the ambassador to the future

Tilly Lockey, 14, lost her hands as a toddler, but sees it as a massive opportunity to embrace technology. She chatted with ARTHUR GOLDSTUCK about the human of tomorrow.

It is a description that defines 14-year-old Tilly Lockey: She lost her hands at the age of 15 months, and now uses bionic hands to show the world how to overcome disability.

That could easily read as an advertisement for a prosthetics company, but Tilly refuses to be defined by marketing messages. She has not only embraced what is supposed to be a disability, but wants to become nothing less than an ambassador to the future.

That is in effect what she is achieving by pushing the boundaries of what is possible with artificial hands. It means that, eventually, she will have more capabilities built into her body than most able-bodied humans can imagine. She collaborates closely with Open Bionics, a start-up that is using 3D printing to create low-cost prosthetics with high-tech capabilities.

“I have very high hopes for the future,” she said during a chat on the sidelines of the SingularityU Summit at Kyalami north of Johannesburg. From Newcastle-on-Tyne in the United Kingdom, she was at the Summit as a guest speaker, chaperoned by her father Adam and sister Tia. 

“When I started working with Open Bionics, I wanted it to include lighting, music, Bluetooth, a projector in my palm, all over-optimistic things. But then I feel that is not too far away, and then a disability would turn into and enhancement of normal human hands. I’m really excited about it.

“I know there’s a couple of things they are working on right now, like trying to get the built-in battery thinner, because it’s hard to get overcoats and jackets over it, so they are trying to get the hands slimmer. They’re working on haptic feedback, to give a sense of touch of vibration, which tells me of I have a good grip on something. It could be coming soon. These hands I’m using now were made in the past five years. In another five years, I think we’ll have all of it.”

The hands in question are called Hero Arms, which its creators, Open Bionics, say is “the world’s first clinically approved 3D-printed bionic arm, with multi-grip functionality and empowering aesthetics”.

How Tilly Lockey became a Hero

Part 2 of ARTHUR GOLDSTUCK’s interview with Tilly Lockey explores her amazing career.

Published

This is the second part of this series of articles. To start from the beginning, click here.

Tilly Lockey was diagnosed with Meningococcal Septicaemia Strain B when she was 15 months old.

Her mother spotted the tell-tale signs one day in 2007: a fast-spreading skin rash that looks like pinpricks, along with symptoms like lethargy and bruising. She was rushed to hospital, but the bacterial poisoning spread so aggressively, doctors gave Tilley no chance of survival. They had to make a quick decision to amputate her hands to save her life.

Twelve years later, her future truly came into focus: “I was surprised with really cool Alita: Battle Angel bionic Hero Arms and went on the blue carpet at the world premiere of the movie with Rosa Salazar and director James Cameron.”

That pivotal moment in her life would not have been possible without the intensive efforts of her mother, Sara, to raise funds to buy something better than the metal prosthetics issued by the National Health Service in the UK. She increased Tilley’s profile with a campaign to “Give Tilley a Hand”, and today works as a fundraiser and events organiser for the Meningitis Now support group. Her involvement in an event meant she was unable to join Tilley on her trip to South Africa last week, when she spoke at the SingularityU Summit. After coming off stage, Tilley told us that Sara was her biggest inspiration in her life, and the closest to a role model.

“I’m usually a speaker at her events. I tell everyone my story and what I’m doing now and give these kids inspiration, because they often feel they can’t do anything because of what Meningitis did to them.

“I am home schooled now, which is pretty cool, because I’m able to have a career and get educated at the same time. I feel I can do a lot of things that friends can’t do. I can take a whole class on an aeroplane. I have a great time traveling and meeting so many inspiring people who are making a difference in the world.”

The form of Mengingitis that attacked her leaves hidden scars and issues that only become apparent years later. She is almost absurdly cheerful about the challenges that have faced her.

“I personally figured out that my left leg had stopped growing. I’m still finding out things it has caused, but you survive. At least I’m here and I’m alive.”

It does help that she’s comfortable in the spotlight, happy to give interviews, and eager to show what she can do with her bionic hands.

“I want to go into public speaking a lot more, and it could be an option as career. I want it to continue because it’s a lot of fun, and I feel I’ve got a story to share. If I can inspire people to change the world, I will. “

Her travels this year will still take her to Barcelona, Jakarta and New York. In the Big Apple, she will accept a humanitarian award, and intends “to give a funky speech”.

In Jakarta, Indonesia, she will take part in a fashion catwalk and do a makeup tutorial live. She learned to do makeup with one of her bionic hands when she fractured her right elbow in a fall at school

“I got makeup for Christmas and wanted to play with it, and got the idea of doing it with an open hand. It took a lot of perseverance and patience, but after studying how to do it, I was able to recreate a full makeup routine using one hand. It wasn’t a great situation at the time, but now I’m happy it happened because it got me into doing what I do now.”

What she is doing with makeup is remarkable in its own right. She gives tutorials on YouTube, where she says she is “kinda new”, as she has “only around 16,000 followers”. That may well soon expand into cooking videos.

In other words, everything is an opportunity: “I could be sad, just sit on my bed and cry, or I can live my life and realise what I’ve got: these amazing bionic Hero Arms.

“All I want to do is help give people confidence in themselves, accept who they are, accept their scars and everything about them. That they don’t have to impress everybody and just be themselves.”
