Critical Flaws in VxWorks affect 200 Million Connected Things

Serious and exploitable security flaws in VxWorks, a commonly used operating system for embedded devices, span 13 years and could leave hundreds of millions* of connected devices vulnerable to remote cyber attacks and hacks. The security firm Armis on Monday published a warning about 11 critical, zero day vulnerabilities in the VxWorks operating system, which is owned and managed by the firm Wind River. The vulnerabilities expose more than 200 million devices and could allow attackers to remotely take control of everything from networked printers and security appliances to industrial and medical devices, according to Ben Seri, the Vice President of Research at Armis. Move over, EternalBlue! At least a couple of the flaws were described as “more serious” than EternalBlue, the Microsoft Windows flaw that powered both the WannaCry and NotPetya malware outbreaks. SCADA and industrial control system devices, healthcare devices like patient monitors and MRI machines, as well […]

Die Hard is a Movie About Building Automation Insecurity. Discuss.

In this episode of the Security Ledger Podcast (#126): Die Hard has finally been embraced as the bloody, violent, feel-good Christmas movie its always been. But the film, which turns 30 this year, is about more than the power of ordinary guys to stand up to evil. Did you know it’s also a (very) early warning about the dire insecurity of building automation systems? We speak with Ang Cui of the firm Red Balloon Security about the dire risk of cyber attacks on building automation software and company’s work to secure this often-overlooked critical infrastructure.

Also: Mark Loveless of DUO discusses his research into how poor implementation of wireless protocols make personal security trackers a privacy risk. And have we seen peak ransomware? Adam Kujawa of the firm Malwarebytes joins us to talk about the findings of that company’s State of Malware Report. 

Researchers Warn of Physics-Based Attacks on Sensors

Billions of sensors that are already deployed lack protections against attacks that manipulate the physical properties of devices to cause sensors and embedded devices to malfunction, researchers working in the U.S. and China have warned.
