Root Causes: A PKI and Security Podcast

Inexpensive and easily obtained deepfake photographs of IDs, generated by AI, are available online. These pose a problem for KYC initiatives.

In the latest in our ongoing series of discussions of the Bugzilla Bloodbath, we delve deep into the problem of failure to revoke on time and the multiple causes that lead to this ongoing failure. And what to do about them.

If you issue public certificates that are fully compliant except that they do not reflect what your CPS says, are they misissued? Do they require revocation? This is a question with real stakes as we see multiple current instances of a CA denying revocation for that reason. In this episode we explore this issue.

Gartner has released a new framework for Certificate Lifecycle Management, called the Seven Core Functions of Certificate Automation. We walk through this framework and answer how it fits in with our own Five Pillars of CLM.

In this guest episode we discuss name space hygiene with Geir Rasmussen, founder of NodeZro. CNAMEs, SPF, DMARC, name server entries, and other DNS identifiers, left unattended, can expose companies to identity-based attacks. We lay out the steps in addressing name space cleanup.

NIST Cyber Security Framework version 2.0 is released. It includes guidance on identity management and authentication. In this first episode of a series, we describe this framework's basic structure and its effect on industry.

A massive name space attack has hijacked more than 21,000 domains and subdomains, including a who's who list of major global brands. This huge and innovative attack takes advantage of inherited trust in abandoned domains. We explain what is happening.

It's a bloodbath on Bugzilla. Since March 9, more than 25 new Bugzilla bugs been written up, which is 10x the typical pace. And it's not over. In this episode we explain what is going on and why.

A ballot for Multi-perspective Issuance Corroboration (MPIC), formerly known as MPDV, has entered a discussion period in the CA/Browser Forum (CABF). We explain the details of what it contains.

An evolving incident on Bugzilla has garnered a lot of attention and touches several important issues in the WebPKI ecosystem. We report what went on and unpack the issues involved.

Apple has announced that iMessage will employ post-quantum cryptography (PQC). We explain the implications of this announcement.

What has been known as CRYSTALS-Kyber now has the new official name of Module Lattice-based Key Encryption Module, or ML-KEM. We give an update on the state of the NIST round 3 winners.

A story circulated earlier this year about a botnet composed of millions of IoT toothbrushes, which later was debunked. We tell you the whole tale.

eIDAS 2.0 has been making headlines recently with its proposed expansion to the European digital identity ecosystem. But what is eIDAS? What does it do, and why does it exist? In this episode we give you the basics.

In this episode we explain subdomain hijacking, including dangling subdomains and how they can constitute vulnerabilities.

Deepfakes continue to show themselves as part of the standard criminal toolkit. A recent deepfake spear phish enabled a $25 million Business Email Compromise (BEC). We explain what happened.

CloudFlare recently published details of an attack it suffered as a downstream effect of a November 2023 breach against Okta and what it did to nullify its success. We discuss the steps enterprises can take to protect themselves against malicious use of stolen access credentials.

In this episode we share the details of a recent nation state actor attack on Microsoft and some of the lessons learned.

In this episode we examine commonly held belief that on-premise systems give system administrators greater levels of control and that that is better for security or other reasons. We explore the pros and cons of extra control, to what degree it is a benefit, and if it's worth it.

A deepfake of Joe Biden's voice made an appearance in robocalls leading up to the New Hampshire primary. We discuss this latest development and its implications.

With maximum 90-day term coming for public SSL certificates and DCV reuse also moving to 90 days, we explain why we do not expect a similar reduction in the reuse period for organization validation.

In this episode we present a catalog of "security questionnaire sins," which are avoidable problems and errors that frequently occur in the security questionnaires enterprises send to vendors. Categories include difficulty of access, poor technical implementation, poor policies, and poor questions.

Three major camera manufacturers have joined to create a standard for signed digital images from their cameras.

Multi-perspective Domain Validation (MPDV) is a necessary evolution of Domain Control Validation (DCV) to protect against Border Gateway Protocol (BGP) attacks. We explore how MPDV may affect accepted DCV methods, especially the email method.

In this episode we explore whether a managed PKI provider should give complete control over PKI decisions to the end customer or if it should enforce certain minimum standards and principles regardless of what the customer asks for.
