#237 - Intel Chat: Black Hat roundup - Gemini AI, NeuralTrust & SPLX, VisionSpace Tech, BCM5820X - & CISA/FEMA grant funding

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

• At Black Hat USA in Las Vegas, three security researchers demonstrated how Google's Gemini AI could be hijacked to take control of smart home devices using a novel form of indirect prompt injection.
• Two separate security teams - NeuralTrust and SPLX - have conducted red teaming evaluations of the newly released GPT-5, and both report serious deficiencies in the model’s security posture.
• Another Black Hat story, security researchers Milenko Starcik and Andrzej Olchawa from VisionSpace Technologies presented a compelling case that hacking satellites is not only more cost-effective than deploying anti-satellite missiles, but alarmingly easy due to widespread software vulnerabilities.
• Our final Black Hat story, Cisco Talos researchers disclosed five critical vulnerabilities in Broadcom’s BCM5820X series chips, used in Dell’s ControlVault3 secure enclave hardware.
• CISA and FEMA have jointly announced over $100 million in cybersecurity grant funding for the 2025 fiscal year, targeting state, local, and tribal governments.
