of the in-progress book on Linear Algebra, “A birds eye view of linear algebra”. This book will put a special emphasis on AI applications and how they leverage linear algebra. Linear algebra is a fundamental discipline underlying anything one can do with Math. From Physics to machine learning, probability theory (ex: Markov chains), you name it. No matter what you’re doing, linear algebra is always lurking under the covers, ready to spring at you as soon as things go multi-dimensional. In my experience (and I’ve heard this from others), this was at the source of a big shock between high school and university. In high…

David Fletcher// Join David as he takes a look at one of the many labs that we’ll be offering during Wild West Hackin’ Fest. This lab explores signal analysis and replay attacks executed by Samy Kamkar. The objective is to interpret signals and perform attacks against simple RF wireless systems that we see in everyday life around us. Those attending WWHF will get to complete these labs in person. Brave souls can win a prize for running up the BHIS flag!!   Slides Here: https://www.dropbox.com/s/9xbdj1escpl69z4/RF_Lab_Webcast%20%282%29.pptx?dl=0 Ready to learn more?

In a post on Bugzilla, Mozilla confirmed that Firefox 139 re-enabled a specific DirectComposition path behavior, which caused these issues. In previous releases, Firefox kept…

In brief The wallet behind the trade had built a 40x leveraged long on Bitcoin before being wiped out. The position unraveled even as Bitcoin stayed within a narrow 2% trading range, according to a pseudonymous trading account belonging to “Pentoshi.” Hyperliquid’s on-chain records showed the trader had initially deposited $3 million in stablecoins.

The U.S. government today imposed economic sanctions on Funnull Technology Inc., a Philippines-based company that provides computer infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was being used as a content delivery network that catered to cybercriminals seeking to route their traffic through U.S.-based cloud providers. “Americans lose billions of dollars annually to these cyber scams, with revenues generated from these crimes rising to record levels in 2024,” reads a statement from the U.S. Department of the Treasury, which sanctioned Funnull…

The 2024 Swedish tournament mirrors similar extreme right-wing martial arts tournaments hosted elsewhere in Europe for years. It also indicates the success of the Active Club model in spreading to the European continent. There are dozens of the fight clubs throughout Europe, including more than 50 in France and several in the United Kingdom, where they came under new scrutiny following a February 2025 ITV documentary connecting members to terrorism and violence. The European Active Clubs are also networking increasingly across national boundaries—Swedish Active Club members were present alongside their Dutch and French comrades at a May 10 fascist march…

Cisco unveiled Duo Identity and Access Management (IAM), a new security solution that transforms how organizations combat persistent identity-based attacks that are accelerating in the AI era. Identity is a prime target for bad actors, accounting for 60% of Cisco Talos Incident Response cases in 2024, because current solutions have critical weaknesses that attackers exploit. Duo IAM offers an innovative and security-first approach, with added protection built on its globally trusted multifactor authentication (MFA). Duo IAM is the latest advancement in Cisco’s long-standing commitment to user-friendly Zero Trust security. “The security industry is facing an ‘identity crisis’ as persistent identity-based attacks…

New research from Cyolo found that 67 percent of respondents across the manufacturing sector identified improved third-party collaboration as the leading benefit of secure remote access. Fifty-eight percent reported increased operational efficiency, while half cited significant cost savings. These findings suggest that secure access is more than just a protective measure, as it creates measurable value across the enterprise. The shift challenges the long-standing narrative in the manufacturing sector and comes as the research challenges common assumptions that cybersecurity hinders productivity, showing that these leaders increasingly see secure remote access as a catalyst for business growth and operational efficiency. Titled…
