Prometheus ransomware’s flaws inspired researchers to try to build a near-universal decryption tool

This blog is part of our live coverage from RSA Conference 2022: Prometheus—a ransomware build based on Thanos that locked up victims’ computers in the summer of 2021—included a major “vulnerability” that led security researchers at IBM to try and build a one-size-fits-all ransomware decryptor th...

Insecure Cryptographic Function

ssh.net is vulnerable to Insecure Cryptographic Function. The vulnerability exists in Start function in KeyExchangeECCurve25519.cs due to the use of cryptographically insecure random number generator which allows an attacker to easily predict the generated pseudo-random values...

Code injection

SSH.NET is a Secure Shell SSH library for .NET. In versions 2020.0.0 and 2020.0.1, during an X25519 key exchange, the client’s private key is generated with System.Random. System.Random is not a cryptographically secure random number generator, it must therefore not be used for cryptographic...

CVE-2022-29245 Weak private key generation in SSH.NET

SSH.NET is a Secure Shell SSH library for .NET. In versions 2020.0.0 and 2020.0.1, during an X25519 key exchange, the client’s private key is generated with System.Random. System.Random is not a cryptographically secure random number generator, it must therefore not be used for cryptographic...

GHSA-GWF7-VFJF-WF6X matrix-sydent and matrix-synapse Use Cryptographically Weak PRNG

An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID...

CVE-2020-28924

An issue was discovered in Rclone before 1.53.3. Due to the use of a weak random number generator, the password generator has been producing weak passwords with much less entropy than advertised. The suggested passwords depend deterministically on the time the second rclone was started. This limi...

PT-2022-7279 · Linux +2 · Linux Kernel +2

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the qcom rng read function in the Linux kernel, which can cause an infinite loop when the max value is not a multiple of WORD SZ. This can be reproduced by...

Java Cryptography Implementation Mistake Allows Digital-Signature Forgeries

Interesting implementation mistake: The vulnerability, which Oracle patched on Tuesday, affects the company’s implementation of the Elliptic Curve Digital Signature Algorithm in Java versions 15 and above. ECDSA is an algorithm that uses the principles of elliptic curve cryptography to authentica...

CVE-2022-26852

Dell PowerScale OneFS, versions 8.2.x-9.3.x, contain a predictable seed in pseudo-random number generator. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to an account compromise...

Use of cryptographically weak random number generator for password generation

Description Umbraco has a GeneratePassword function that is used to generate passwords that should be unpredictable, this function uses the .NET Random class which isn't cryptographically secure. Impact This vulnerability is capable of allowing attackers to predict generated passwords and use the...

Linux Improves Its Random Number Generator

In kernel version 5.17, both /dev/random and /dev/urandom have been replaced with a new -- identical -- algorithm based on the BLAKE2 hash function, which is an excellent security improvement...
