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.

Welcome to world of 2099
The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says one visionary. ARTHUR GOLDSTUCK met him in Singapore.
Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks. Cosmetic stores sell their wares via public touch-screens, with products delivered instantly in drawers below the screens.
This is not a vision of the future. It is a sample of Singapore today. But it is also an inkling of the world we may all experience in the future.
Singapore was the venue, last week, of the World Cities Summit, where engineers, politicians, investors and visionaries rubbed shoulders as they talked about the strategies and policies that would enhance urban living in the future.
As part of the Summit, global payment technologies leader Mastercard hosted a small media briefing by one of Singapore’s leading thinkers about the future, Dr Damian Tan, managing director of Vickers Venture Partners. The company’s slogan “We invest in the extraordinary,” offers a small clue to Tan’s perspective.
“We look as far forward as 2099 because, as a venture capital firm, we invest in the long term,” he tells a group of journalists from Africa and the Middle East. “Companies explode in growth because there is value in the future. If there is no growth, they won’t explode.”
The big question that the Smart Cities Summit and Mastercard are trying to help answer is, what will cities look like in the year 2099? Tan can’t give an exact answer, but he offers a framework that helps one approach the question.
“If you want to look at 81 years into the future, and understand the change that will come, you need to double that amount and look into the past. That takes us to 1856. The difference between then and now is the difference you can expect between now and 2099.”

Street art goes electric
Kaspersky Lab and British street artist D*Face have unveiled the first-ever “art helmet” design at the Formula E finale for electric cars in New York.
The ‘Save The World’ helmets will be raced by DS Virgin Racing’s drivers, Sam Bird and Alex Lynn, as they traverse the New York street circuit during the final races of the Formula E season.
The announcement signals the first art helmet by a Formula E team, continuing the heritage of art in motorsport and the cybersecurity brand’s commitment to contemporary art, creativity and innovation. D*Face took inspiration from Kaspersky Lab’s tagline, “A Company To Save The World”, and hopes that his colourful work will inspire people to take positive action.
D*Face will announce his first-ever art car design with a custom-made livery for the DS Virgin Racing Team. Its design will be released at the “Art Goes Green” event after Saturday’s race. The helmets and art car are the latest installations in the “Save the World” collection, following a major permanent public mural that was installed in Brooklyn, New York, in May.
D*Face, whose real name is Dean Stockton, said: “It is exciting to work with Kaspersky Lab on this project and create art with a real message of hope for a better future. After all, this is our world and we need to look after it. It will take every one of us to make a real lasting, impactful change. I love the mentality of the DS Virgin Racing Team and that of Formula E by showcasing sport in a way that doesn’t harm the environment, but is still just as exhilarating and fun.
“It is time for us all to stand together and make a change… be that stopping data steals, climate change, plastic waste or using damaging fuels. I want everyone to make a pledge to do one thing that will help make a change.”
As a sponsor of DS Virgin Racing Team, Kaspersky Lab is responsible for protecting the team’s devices against cyber threats. The company sees the technical environment in the global sport of Formula E as the next frontier in furthering its research and development of new technologies to keep vehicles secure in the digital world.
Sylvain Filippi, Managing Director at DS Virgin Racing, said: “The whole team fully supports this great initiative and our thanks got to Kaspersky and D*Face for their collaboration. It’s an honour to have such an innovative artist bring his talents to bear in our team ahead of the season-finale; the car, drivers’ crash helmets and mural all look amazing.”
Aldo Fucelli Pessot del Bo, Head of Global Partnerships and Sponsorships at Kaspersky Lab added: “There is a need for innovation on a global scale, both in contemporary art and in the fast-growing sport of Formula E. Now, for the first time ever, Kaspersky Lab is proudly bringing together the two sectors in an effort to Save the World and unleash creativity, encourage freedom of expression and further innovation.”
