Suprising no one, the security of police bodycams is terrible. Mitchell even realized that because he can remotely access device storage on models like the Fire Cam OnCall, an attacker could potentially plant malware on some of the cameras. Then, when the camera connects to a PC for syncing, it could deliver all sorts of … Read More “Hacking Police Bodycams” »
Bluetooth has a serious security vulnerability: In some implementations, the elliptic curve parameters are not all validated by the cryptographic algorithm implementation, which may allow a remote attacker within wireless range to inject an invalid public key to determine the session key with high probability. Such an attacker can then passively intercept and decrypt all … Read More “Major Bluetooth Vulnerability” »
Interesting research in using traffic analysis to learn things about encrypted traffic. It’s hard to know how critical these vulnerabilities are. They’re very hard to close without wasting a huge amount of bandwidth. The active attacks are more interesting. Powered by WPeMatico
The IEEE came out in favor of strong encryption: IEEE supports the use of unfettered strong encryption to protect confidentiality and integrity of data and communications. We oppose efforts by governments to restrict the use of strong encryption and/or to mandate exceptional access mechanisms such as “backdoors” or “key escrow schemes” in order to facilitate … Read More “IEEE Statement on Strong Encryption vs. Backdoors” »
Last week, researchers disclosed vulnerabilities in a large number of encrypted e-mail clients: specifically, those that use OpenPGP and S/MIME, including Thunderbird and AppleMail. These are serious vulnerabilities: An attacker who can alter mail sent to a vulnerable client can trick that client into sending a copy of the plaintext to a web server controlled … Read More “E-Mail Vulnerabilities and Disclosure” »
Google and Microsoft researchers have disclosed another Spectre-like CPU side-channel vulnerability, called “Speculative Store Bypass.” Like the others, the fix will slow the CPU down. The German tech site Heise reports that more are coming. I’m not surprised. Writing about Spectre and Meltdown in January, I predicted that we’ll be seeing a lot more of … Read More “Another Spectre-Like CPU Vulnerability” »
A new PGP vulnerability was announced today. Basically, the vulnerability makes use of the fact that modern e-mail programs allow for embedded HTML objects. Essentially, if an attacker can intercept and modify a message in transit, he can insert code that sends the plaintext in a URL to a remote website. Very clever. The EFAIL … Read More “Details on a New PGP Vulnerability” »
EFF is reporting that a critical vulnerability has been discovered in PGP and S/MIME. No details have been published yet, but one of the researchers wrote: We’ll publish critical vulnerabilities in PGP/GPG and S/MIME email encryption on 2018-05-15 07:00 UTC. They might reveal the plaintext of encrypted emails, including encrypted emails sent in the past. … Read More “Critical PGP Vulnerability” »
Researchers have disclosed a massive vulnerability in the VingCard eletronic lock system, used in hotel rooms around the world: With a $300 Proxmark RFID card reading and writing tool, any expired keycard pulled from the trash of a target hotel, and a set of cryptographic tricks developed over close to 15 years of on-and-off analysis … Read More “Security Vulnerabilities in VingCard Electronic Locks” »
This vulnerability is a result of an interaction between two different ways of handling e-mail addresses. Gmail ignores dots in addresses, so bruce.schneier@gmail.com is the same as bruceschneier@gmail.com is the same as b.r.u.c.e.schneier@gmail.com. (Note: I do not own any of those email addresses — if they’re even valid.) Netflix doesn’t ignore dots, so those are … Read More “Obscure E-Mail Vulnerability” »
