EulerOS Virtualization for ARM 64 3.0.6.0 : nss-softokn (EulerOS-SA-2021-1536)

According to the versions of the nss-softokn packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities : - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS. When using multi-part Chacha20, it could...

Cloning Google Titan 2FA keys

This is a clever side-channel attack: The cloning works by using a hot air gun and a scalpel to remove the plastic key casing and expose the NXP A700X chip, which acts as a secure element that stores the cryptographic secrets. Next, an attacker connects the chip to hardware and software that take...

New Attack Could Let Hackers Clone Your Google Titan 2FA Security Keys

Hardware security keys—such as those from Google and Yubico—are considered the most secure means to protect accounts from phishing and takeover attacks. But a new research published on Thursday demonstrates how an adversary in possession of such a two-factor authentication 2FA device can clone it...

Design/Logic Flaw

An electromagnetic-wave side-channel issue was discovered on NXP SmartMX / P5x security microcontrollers and A7x secure authentication microcontrollers, with CryptoLib through v2.9. It allows attackers to extract the ECDSA private key after extensive physical access and consequently produce a...

Air-Gap Attack Turns Memory Modules into Wi-Fi Radios

Super-secure air-gapped computers are vulnerable to a new type of attack that can turn a PC’s memory module into a modified Wi-Fi radio, which can then transmit sensitive data at 100 bits-per-second wirelessly to nearly six feet away. Noted air-gap researcher Mordechai Guri created the...

Exfiltrating Data from Air-Gapped Computers via Wi-Fi Signals (Without Wi-Fi Hardware)

A security researcher has demonstrated that sensitive data could be exfiltrated from air-gapped computers via a novel technique that leverages Wi-Fi signals as a covert channel—surprisingly, without requiring the presence of Wi-Fi hardware on the targeted systems. Dubbed "AIR-FI," the attack hing...

nss: ECDSA timing attack mitigation bypass

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...
