In this episode of The Cybersecurity Defenders Podcast, we discuss some intel being shared in the LimaCharlie community.

• A high-profile phishing incident has resulted in the compromise of several widely-used JavaScript packages on npm, after a developer known as "Qix" inadvertently clicked a malicious link from a fake support email.
• Multiple undersea cable cuts in the Red Sea have led to degraded internet connectivity across the Middle East and South Asia, affecting key infrastructure and cloud services.
• North Korean-aligned threat actors operating under the Contagious Interview campaign have been systematically abusing cyber threat intelligence (CTI) platforms to monitor exposure of their own infrastructure and scout for new assets.
• Researchers from Ontinue have detailed a sophisticated phishing campaign leveraging the Salty2FA phishing kit - a framework that reflects how cybercriminal tooling is increasingly mimicking enterprise-grade software in terms of design, capability, and operational maturity.

On this episode of the Cybersecurity Defenders Podcast we speak with Robert Boles, Founder / CEO of BLOKWORX.

A veteran of the U.S. Marine Corps, Rob founded BLOKWORX in 2006 to further his passion for creating fast, secure networks. Since 1999 Rob was a core technical contributor and presenter on an Advanced IP Team, delivering bleeding edge WAN and Managed Security services to Small, Mid-level and Fortune 500 businesses around the world.

The experience led him back to the same conclusion, regardless of size and resources, every company struggled with the same uncertainty – multiple vendors with infinite solutions, and no real clarity how to make it all “work.” Rob focused BLOKWORX on security, reliability, and positive user experience. He has built a team that leverages their expertise with extensive research and testing, alignment with vendors, partners, and clients, and the experience of 1000’s of nodes managed and monitored, all supported by a mature delivery model built on years of operational experience. Rob is an avid outdoorsman and his favorite place to be is in a raft or a kayak with his son Jack.
