Back in January, we learned about a class of vulnerabilities against microprocessors that leverages various performance and efficiency shortcuts for attack. I wrote that the first two attacks would be just the start: It shouldn’t be surprising that microprocessor designers have been building insecure hardware for 20 years. What’s surprising is that it took 20 … Read More “More Spectre/Meltdown-Like Attacks” »
This is really just to point out that computer security is really hard: Almost as soon as Apple released iOS 12.1 on Tuesday, a Spanish security researcher discovered a bug that exploits group Facetime calls to give anyone access to an iPhone users’ contact information with no need for a passcode. […] A bad actor … Read More “iOS 12.1 Vulnerability” »
Consumer Reports is starting to evaluate the security of IoT devices. As part of that, it’s reviewing wireless home-security cameras. It found significant security vulnerabilities in D-Link cameras: In contrast, D-Link doesn’t store video from the DCS-2630L in the cloud. Instead, the camera has its own, onboard web server, which can deliver video to the … Read More “Consumer Reports Reviews Wireless Home-Security Cameras” »
Interesting research: “Self-encrypting deception: weaknesses in the encryption of solid state drives (SSDs)“: Abstract: We have analyzed the hardware full-disk encryption of several SSDs by reverse engineering their firmware. In theory, the security guarantees offered by hardware encryption are similar to or better than software implementations. In reality, we found that many hardware implementations have … Read More “Security of Solid-State-Drive Encryption” »
This seems bad: The F25 software was found to contain a capture replay vulnerability — basically an attacker would be able to eavesdrop on radio transmissions between the crane and the controller, and then send their own spoofed commands over the air to seize control of the crane. “These devices use fixed codes that are … Read More “Security Vulnerability in Internet-Connected Construction Cranes” »
The US Government Accounting Office just published a new report: “Weapons Systems Cyber Security: DOD Just Beginning to Grapple with Scale of Vulnerabilities” (summary here). The upshot won’t be a surprise to any of my regular readers: they’re vulnerable. From the summary: Automation and connectivity are fundamental enablers of DOD’s modern military capabilities. However, they … Read More “Security Vulnerabilities in US Weapons Systems” »
Of course the ESS ExpressVote voting computer will have lots of security vulnerabilities. It’s a computer, and computers have lots of vulnerabilities. This particular vulnerability is particularly interesting because it’s the result of a security mistake in the design process. Someone didn’t think the security through, and the result is a voter-verifiable paper audit trail … Read More “Security Vulnerability in ESS ExpressVote Touchscreen Voting Computer” »
A security vulnerability in Belkin’s Wemo Insight “smartplugs” allows hackers to not only take over the plug, but use it as a jumping-off point to attack everything else on the network. From the Register: The bug underscores the primary risk posed by IoT devices and connected appliances. Because they are commonly built by bolting on … Read More “Security Vulnerability in Smart Electric Outlets” »
This is really interesting research: “BlackIoT: IoT Botnet of High Wattage Devices Can Disrupt the Power Grid“: Abstract: We demonstrate that an Internet of Things (IoT) botnet of high wattage devices — such as air conditioners and heaters — gives a unique ability to adversaries to launch large-scale coordinated attacks on the power grid. In … Read More “Using Hacked IoT Devices to Disrupt the Power Grid” »
Another speculative-execution attack against Intel’s SGX. At a high level, SGX is a new feature in modern Intel CPUs which allows computers to protect users’ data even if the entire system falls under the attacker’s control. While it was previously believed that SGX is resilient to speculative execution attacks (such as Meltdown and Spectre), Foreshadow … Read More “Speculation Attack Against Intel’s SGX” »
