The cryptocurrency fintech startup Prime Trust lost the encryption key to its hardware wallet—and the recovery key—and therefore $38.9 million. It is now in bankruptcy. I can’t understand why anyone thinks these technologies are a good idea. Powered by WPeMatico
Cryptographic flaws still matter. Here’s a flaw in the random-number generator used to create private keys. The seed has only 32 bits of entropy. Seems like this flaw is being exploited in the wild. Powered by WPeMatico
A bunch of networks, including US Government networks, have been hacked by the Chinese. The hackers used forged authentication tokens to access user email, using a stolen Microsoft Azure account consumer signing key. Congress wants answers. The phrase “negligent security practices” is being tossed about—and with good reason. Master signing keys are not supposed to … Read More “Microsoft Signing Key Stolen by Chinese” »
A bunch of Android OEM signing keys have been leaked or stolen, and they are actively being used to sign malware. Łukasz Siewierski, a member of Google’s Android Security Team, has a post on the Android Partner Vulnerability Initiative (AVPI) issue tracker detailing leaked platform certificate keys that are actively being used to sign malware. … Read More “Leaked Signing Keys Are Being Used to Sign Malware” »
Suspected members of a European car-theft ring have been arrested: The criminals targeted vehicles with keyless entry and start systems, exploiting the technology to get into the car and drive away. As a result of a coordinated action carried out on 10 October in the three countries involved, 31 suspects were arrested. A total of … Read More “Hacking Automobile Keyless Entry Systems” »
Nice work: Radio relay attacks are technically complicated to execute, but conceptually easy to understand: attackers simply extend the range of your existing key using what is essentially a high-tech walkie-talkie. One thief stands near you while you’re in the grocery store, intercepting your key’s transmitted signal with a radio transceiver. Another stands near your … Read More “Relay Attack against Teslas” »
This is a dumb crypto mistake I had not previously encountered: A developer says it was possible to run their own software on the car infotainment hardware after discovering the vehicle’s manufacturer had secured its system using keys that were not only publicly known but had been lifted from programming examples. […] “Turns out the … Read More “Hyundai Uses Example Keys for Encryption System” »
My personal definition of a brilliant idea is one that is immediately obvious once it’s explained, but no one has thought of it before. I can’t believe that no one has described this taxonomy of access control before Ittay Eyal laid it out in this paper. The paper is about cryptocurrency wallet design, but the … Read More “A Taxonomy of Access Control” »
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 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” »
