Bitcoin wallets created between 2011 and 2015 are susceptible to a new kind of exploit called Randstorm that makes it possible to recover passwords and gain unauthorized access to a multitude of wallets spanning several blockchain platforms. "Randstorm() is a term we coined to describe a collection of bugs, design decisions, and API changes that, when brought in contact with each other, combine

Plus: The FBI's baffling inaction on a ransomware group, a massive breach of Danish electric utilities, and more.

### Summary The json-web-token library is vulnerable to a JWT algorithm confusion attack. ### Details On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To exploit this vulnerability, an attacker needs to craft a malicious JWT token containing the HS256 algorithm, signed with the public RSA key of the victim application. This attack will only work against this library is the RS256 algorithm is in use, however it is a best practice to use that algorithm. ### PoC Take a server running the following code: ```javascript const express = require('express'); const jwt = require('json-web-token'); const fs = require('fs'); const path = require('path'); const app = express(); const port = 3000; // Load the keys from the file const publicKeyPath = path.join(__dirname, 'public-key.pem'); const publicKey = fs.readFileSync(publicKeyPath, 'utf8'); ...

joaquimserafim/json-web-token is a javascript library use to interact with JSON Web Tokens (JWT) which are a compact URL-safe means of representing claims to be transferred between two parties.

An unknown threat actor has been observed publishing typosquat packages to the Python Package Index (PyPI) repository for nearly six months with an aim to deliver malware capable of gaining persistence, stealing sensitive data, and accessing cryptocurrency wallets for financial gain. The 27 packages, which masqueraded as popular legitimate Python libraries, attracted thousands of downloads,
