Honda vehicles from 2021 to 2022 are vulnerable to this attack: On Thursday, a security researcher who goes by Kevin2600 published a technical report and videos on a vulnerability that he claims allows anyone armed with a simple hardware device to steal the code to unlock Honda vehicles. Kevin2600, who works for cybersecurity firm Star-V … Read More “Security Vulnerabilities in Honda’s Keyless Entry System” »

Hertzbleed: A New Side-Channel Attack

Posted on June 22, 2022 By infossl
cryptography, keys, Security technology, side-channel attacks, Uncategorized

Hertzbleed is a new side-channel attack that works against a variety of microprocressors. Deducing cryptographic keys by analyzing power consumption has long been an attack, but it’s not generally viable because measuring power consumption is often hard. This new attack measures power consumption by measuring time, making it easier to exploit. The team discovered that … Read More “Hertzbleed: A New Side-Channel Attack” »

Breaking RSA through Insufficiently Random Primes

Basically, the SafeZone library doesn’t sufficiently randomize the two prime numbers it used to generate RSA keys. They’re too close to each other, which makes them vulnerable to recovery. There aren’t many weak keys out there, but there are some: So far, Böck has identified only a handful of keys in the wild that are … Read More “Breaking RSA through Insufficiently Random Primes” »

Determining Key Shape from Sound

It’s not yet very accurate or practical, but under ideal conditions it is possible to figure out the shape of a house key by listening to it being used. Listen to Your Key: Towards Acoustics-based Physical Key Inference Abstract: Physical locks are one of the most prevalent mechanisms for securing objects such as doors. While … Read More “Determining Key Shape from Sound” »

DiceKeys

DiceKeys is a physical mechanism for creating and storing a 192-bit key. The idea is that you roll a special set of twenty-five dice, put them into a plastic jig, and then use an app to convert those dice into a key. You can then use that key for a variety of purposes, and regenerate … Read More “DiceKeys” »

Copying a Key by Listening to It in Action

Researchers are using recordings of keys being used in locks to create copies. Once they have a key-insertion audio file, SpiKey’s inference software gets to work filtering the signal to reveal the strong, metallic clicks as key ridges hit the lock’s pins [and you can hear those filtered clicks online here]. These clicks are vital … Read More “Copying a Key by Listening to It in Action” »

South Africa’s Postbank experienced a catastrophic security failure. The bank’s master PIN key was stolen, forcing it to cancel and replace 12 million bank cards. The breach resulted from the printing of the bank’s encrypted master key in plain, unencrypted digital language at the Postbank’s old data centre in the Pretoria city centre. According to … Read More “Bank Card “Master Key” Stolen” »

Remember Spectre and Meltdown? Back in early 2018, I wrote: Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they — and the research into the Intel ME vulnerability — have shown researchers where to look, more is coming — and what they’ll find will be worse … Read More “Another Intel Speculative Execution Vulnerability” »

Securing Internet Videoconferencing Apps: Zoom and Others

The NSA just published a survey of video conferencing apps. So did Mozilla. Zoom is on the good list, with some caveats. The company has done a lot of work addressing previous security concerns. It still has a bit to go on end-to-end encryption. Matthew Green looked at this. Zoom does offer end-to-end encryption if … Read More “Securing Internet Videoconferencing Apps: Zoom and Others” »
