[Technical Overview] The recent discussion surrounding Dart/Flutter’s pseudo-random number generator (PRNG) highlights a critical misunderstanding of cryptographic security in software development. While using a 32-bit seed for a PRNG is commonplace, the core issue wasn’t the PRNG itself, but rather the widespread misuse of an insecure PRNG for applications demanding cryptographic security. This oversight led to vulnerabilities in various projects that relied on the default Random class for tasks requiring strong randomness....

[Technical Overview] Wazuh is a powerful open-source Security Information and Event Management (SIEM) system that provides real-time threat detection, security monitoring, and compliance auditing capabilities. It leverages a multi-layered approach incorporating log analysis, file integrity monitoring (FIM), and vulnerability detection. Unlike many commercial SIEM solutions, Wazuh’s open-source nature allows for customization, extensibility, and cost-effectiveness. Its architecture is built upon a central management server and multiple agents deployed across various endpoints, enabling centralized monitoring and management of diverse IT infrastructures....
