Good essay on the inherent vulnerabilities in the cell phone standards and the market barriers to fixing them. So far, industry and policymakers have largely dragged their feet when it comes to blocking cell-site simulators and SS7 attacks. Senator Ron Wyden, one of the few lawmakers vocal about this issue, sent a letter in August … Read More “Security Vulnerabilities in Cell Phone Systems” »

No one doubts that artificial intelligence (AI) and machine learning (ML) will transform cybersecurity. We just don’t know how, or when. While the literature generally focuses on the different uses of AI by attackers and defenders ­ and the resultant arms race between the two ­ I want to talk about software vulnerabilities. All software … Read More “Machine Learning to Detect Software Vulnerabilities” »

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” »

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” »

Security Vulnerability in Internet-Connected Construction Cranes

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” »

Security Vulnerability in ESS ExpressVote Touchscreen Voting Computer

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” »
