Git 2.51: Preparing for the future with SHA-256

Git 2.51 is out, and the release continues the long process of modernizing the version control system. The update includes several technical changes, but one of the most important areas of work is Git’s move toward stronger cryptographic security through SHA-256 support. Git has relied on SHA-1 since its creation in 2005. SHA-1 has been showing its age for years, with researchers demonstrating collision attacks that make it unsuitable for long-term use. The community has … More → The post Git 2.51: Preparing for the future with SHA-256 appeared first on Help Net Security.

What happens when penetration testing goes virtual and gets an AI coach

Cybersecurity training often struggles to match the complexity of threats. A new approach combining digital twins and LLMs aims to close that gap. Researchers from the University of Bari Aldo Moro propose using Cyber Digital Twins (CDTs) and generative AI to create realistic, interactive environments for cybersecurity education. Their framework simulates IT, OT, and IoT systems in a controlled virtual space and layers AI-driven feedback on top. The goal is to improve penetration testing skills … More → The post What happens when penetration testing goes virtual and gets an AI coach appeared first on Help Net Security.

As AI grows smarter, your identity security must too

AI is no longer on the horizon, it’s already transforming how organizations operate. In just a few years, we’ve gone from isolated pilots to enterprise-wide adoption. According to a recent SailPoint survey, 82% of companies are running AI agents today, often across multiple business functions. These agents aren’t just passive tools; they’re autonomous systems that act, decide, and adapt at remarkable speed and scale. These systems now handle responsibilities once reserved for skilled human oversight, … More → The post As AI grows smarter, your identity security must too appeared first on Help Net Security.

The cybersecurity myths companies can’t seem to shake

Cybersecurity myths are like digital weeds: pull one out, and another quickly sprouts in its place. You’ve probably heard them before: Macs don’t get viruses, we’re too small to be a target, or changing passwords often keeps us safer. Experts have been busting these myths for years, yet they still stick around and shape bad strategies while giving people a false sense of security. Myth 1: AI can replace your security team No matter how … More → The post The cybersecurity myths companies can’t seem to shake appeared first on Help Net Security.

What makes airport and airline systems so vulnerable to attack?

In this Help Net Security video, Recep Ozdag, VP and GM at Keysight Technologies, explains why airline and airport systems are so difficult to secure. He explores the complex aviation ecosystem, from legacy systems and third-party vendors to the challenges of testing in safety-critical environments. Ozdag emphasizes the importance of packet-level monitoring, real-time validation, and a zero-trust mindset, urging aviation leaders to treat cybersecurity as a core element of safety, not just compliance.
