The Claude Fable Saga - The 443 Podcast - Episode 375

This week on the podcast, we unpack the Claude Fable 5 release and subsequent revocation following an export control directive from the US federal government. After that, we cover the recent FortiBleed credential dump, discussing its likely origins, before reviewing the most recent Windows 0day disclosed by Nightmare Eclipse.

Episode 17 - Home Labs and Tinted Windows: Why Network Visibility Starts at Your Front Door

In this episode, host Richard Bejtlich and guest Ricky Lin explore the practical—and often personal—side of network defense: monitoring the home network. Ricky shares how he uses Corelight and Zeek to track everything from his children's YouTube habits to the constant chatter of IoT devices like Tesla vehicles and smart appliances. They delve into the "tinted windows" analogy to explain why visibility into encrypted traffic is still possible through network metadata, even when the contents are hidden.

20,000 Instagram accounts hacked with AI tool abuse

A bug in Meta's AI-powered account recovery tool compromised 20,000 Instagram accounts. In this week's Intel Chat, Chris and Matt discuss how the flaw allowed attackers to bypass email verification. Meta patched the tool after discovering the abuse on May 31st. Matt's takeaway: tools given broad API access become attractive targets. Meta should have caught this in basic testing, yet it took an adversary to expose the weakness.

An independent code review of Persona's data practices

We believe trust is earned through demonstration and transparency, not promises. That’s why we worked with Trail of Bits, an independent security firm that has spent years reviewing the code behind widely-used software from cryptography libraries to critical open-source infrastructure. Persona regularly undergoes independent third-party audits across our security, privacy, and product programs.

How to layer fraud checks on top of Anthropic's KYC Screener agent

Anthropic released a pre-built KYC Screener agent last month. It runs a four-step workflow on onboarding records to extract structured data from KYC documents, evaluate that data against a firm's KYC rules, screen named parties, and escalate exceptions to a compliance file for human review. The Anthropic template is purpose-built for meeting basic KYC compliance requirements during onboarding, and it lowers the cost of getting it right.

What is continuous application assurance? A new model for enterprise risk

Most CISOs can’t answer a simple question with confidence: are the controls protecting our most critical applications actually working right now? Not last quarter, or the last time someone ran an assessment, but right now. That’s not a failure of effort. Enterprise security teams run on thousands of applications. Each one carries contracts, regulatory obligations, and customer trust.

The World Cup Creates the World's Largest Attack Surface

When 48 teams, 104 matches, 16 host cities, and a broadcast audience approaching half the planet converge across six weeks, something else converges at the same time: opportunity for the people trying to exploit it. The 2026 FIFA World Cup is the most complex digital event in history, and the security challenge it creates is not limited to the tournament organizers.

The Easiest Security Add of 2026 Is Also the Most Urgent

For years, cybersecurity conversations have focused on endpoints, networks, and email. Meanwhile, attackers have quietly shifted their attention elsewhere. Today, many breaches begin in the cloud. Compromised Microsoft 365 accounts. Misconfigured SaaS applications. Third-party integrations with excessive permissions. Employees are adopting AI tools without IT approval. These aren't edge cases anymore; they're becoming everyday realities for managed service providers (MSPs).
