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” »

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” »

There’s a new, practical, collision attack against SHA-1: In this paper, we report the first practical implementation of this attack, and its impact on real-world security with a PGP/GnuPG impersonation attack. We managed to significantly reduce the complexity of collisions attack against SHA-1: on an Nvidia GTX 970, identical-prefix collisions can now be computed with … Read More “New SHA-1 Attack” »

A malicious Chrome extension surreptitiously steals Ethereum keys and passwords: According to Denley, the extension is dangerous to users in two ways. First, any funds (ETH coins and ERC0-based tokens) managed directly inside the extension are at risk. Denley says that the extension sends the private keys of all wallets created or managed through its … Read More “Chrome Extension Stealing Cryptocurrency Keys and Passwords” »

Really interesting research: TPM-FAIL: TPM meets Timing and Lattice Attacks, by Daniel Moghimi, Berk Sunar, Thomas Eisenbarth, and Nadia Heninger. Abstract: Trusted Platform Module (TPM) serves as a hardware-based root of trust that protects cryptographic keys from privileged system and physical adversaries. In this work, we per-form a black-box timing analysis of TPM 2.0 devices … Read More “TPM-Fail Attacks Against Cryptographic Coprocessors” »

There was a successful attack against NordVPN: Based on the command log, another of the leaked secret keys appeared to secure a private certificate authority that NordVPN used to issue digital certificates. Those certificates might be issued for other servers in NordVPN’s network or for a variety of other sensitive purposes. The name of the … Read More “NordVPN Breached” »

Wow, is this an embarrassing bug: Yubico is recalling a line of security keys used by the U.S. government due to a firmware flaw. The company issued a security advisory today that warned of an issue in YubiKey FIPS Series devices with firmware versions 4.4.2 and 4.4.4 that reduced the randomness of the cryptographic keys … Read More “Yubico Security Keys with a Crypto Flaw” »

MongoDB Offers Field Level Encryption

MongoDB now has the ability to encrypt data by field: MongoDB calls the new feature Field Level Encryption. It works kind of like end-to-end encrypted messaging, which scrambles data as it moves across the internet, revealing it only to the sender and the recipient. In such a “client-side” encryption scheme, databases utilizing Field Level Encryption … Read More “MongoDB Offers Field Level Encryption” »
