RT by @TheHackersNews: How long does it take modern attackers to brute-force guess user passwords with the help of newer hardware?

See how long it will take a criminal to brute force guess passwords hashed with MD5.: https://specopssoft.com/blog/best-password-practices-to-defend-against-modern-cracking-attacks/

@kubikpixel @Stark9837 #Encrypting #passwords doesn't get better because you use a library someone else has written to implement the #encryption.

Salted slow #hashing for passwords, yes. (Again, with the exception of #PasswordManagers where passwords really need to be stored securely in a reversible fashion.) But then you still aren't doing #encryption, you're doing #hashing, which was the point of my previous post.

@Stark9837 Passwords should never be stored encrypted. (The one exception being #PasswordManagers.) There is no legitimate reason to store passwords encrypted. Any service which encrypts, rather than hashes, #passwords should be treated as highly suspect.

I know a lot of people don't know the difference, but there is a HUGE one.

#Encryption is by definition reversible.

#Hashing is irreversible (if done right).

That said, I absolutely agree that every #password should be random and unique.

Paper 2023/331 A Vulnerability in Implementations of SHA-3, SHAKE, EdDSA, and Other NIST-Approved Algorithm

Abstract

This paper describes a vulnerability in several implementations of the Secure Hash Algorithm 3 (SHA-3) that have been released by its designers. The vulnerability has been present since the final-round update of Keccak was submitted to the National Institute of Standards and Technology (NIST) SHA-3 hash function competition in January 2011, and is present in the eXtended Keccak Code Package (XKCP) of the Keccak team. It affects all software projects that have integrated this code, such as the scripting languages Python and PHP Hypertext Preprocessor (PHP). The vulnerability is a buffer overflow that allows attacker-controlled values to be eXclusive-ORed (XORed) into memory (without any restrictions on values to be XORed and even far beyond the location of the original buffer), thereby making many standard protection measures against buffer overflows (e.g., canary values) completely ineffective. First, we provide Python and PHP scripts that cause segmentation faults when vulnerable versions of the interpreters are used. Then, we show how this vulnerability can be used to construct second preimages and preimages for the implementation, and we provide a specially constructed file that, when hashed, allows the attacker to execute arbitrary code on the victim's device. The vulnerability applies to all hash value sizes, and all 64-bit Windows, Linux, and macOS operating systems, and may also impact cryptographic algorithms that require SHA-3 or its variants, such as the Edwards-curve Digital Signature Algorithm (EdDSA) when the Edwards448 curve is used. We introduce the Init-Update-Final Test (IUFT) to detect this vulnerability in implementations. #cryptography #encryption #sha #sha3 #cybersecurity #hash #hashing #algorithm #algorithms #nist #nistcybersecurityframework

@campuscodi The need for these confuses me because in 2023 I have a hard time imagining that fitting AES and SHA2 into connection capable microcontrollers on a power budget is difficult. What is my imagination missing?

Introduction to Locality-Sensitive Hashing https://tylerneylon.com/a/lsh1/ #Hashing

[Paper of the day][#18] How do you triage #malware? How do you tell two files are similar? An interesting static analysis approach is to use #similarity #hashing tools, such as #ssdeep and #sdhash. However, to be effective, their application can't be straightforward, but should follow a protocol. In this paper, we discuss how to efficiently apply these functions for malware family classification. We show that hashing only the instruction disassembly has a greater impact than hashing the entire file. Check this result and much more.
