Zero-day bug forces iPhones and iPads to crash and burn

Researchers have revealed a zero-day vulnerability in iOS 8 that, when exploited by a malicious wireless hotspot, will repeatedly crash nearby Apple iPhones, iPads and iPods. The attack will render vulnerable iOS things within range unstable or even entirely unusable by triggering constant reboots.

Anyone can take any router and create a Wi-Fi hotspot that forces you to connect to their network, and then manipulate the traffic to cause apps and the operating system to crash. This is not a denial-of-service where you can't use your Wi-Fi – this is a denial-of-service so you can't use your device even in offline mode.

Can you be sure in a smart TV?

With the continuous advancements made in technology, our online experiences are becoming more streamlined and seemingly user friendly.

We no longer require stationary desktop computers to access the Internet, but instead can reach the web through our laptops, smartphones, tablets and now, televisions.

In January 2014, there was a deeper dive into the safety of smart TVs by inspecting the televisions of major manufactures. Journalists were able to crack into the devices by messing with their SSL certificates.

Microsoft Schannel bug latest in long line of serious crypto flaws

The critical vulnerability in the Schannel technology in Windows that Microsoft patched is ripe for exploitation, experts say, and continues the long line of severe vulnerabilities in major SSL/TLS implementations in recent months.

The technology is in every supported version of Windows, and it can be exploited remotely by unauthenticated attackers. The company said that the vulnerability was found during a “proactive security audit”. That vulnerability enables an attacker to read the memory of systems protected by vulnerable versions of the software under certain circumstances.

POODLE bites: exploiting the SSL 3.0 fallback

There are details of a vulnerability in the design of SSL version 3.0. This vulnerability allows the plaintext of secure connections to be calculated by a network attacker. 

SSL 3.0 is nearly 15 years old, but support for it remains widespread. Most importantly, nearly all browsers support it and, in order to work around bugs in HTTPS servers, browsers will retry failed connections with older protocol versions, including SSL 3.0. Because a network attacker can cause connection failures, they can trigger the use of SSL 3.0 and then exploit this issue. Disabling SSL 3.0 support, or CBC-mode ciphers with SSL 3.0, is sufficient to mitigate this issue, but presents significant compatibility problems, even today.
