While preparing for my Black Hat and DEF CON talks in July of this year, I found the most impactful Entra ID vulnerability that I will probably ever find. One that could have allowed me to compromise every Entra ID tenant in the world (except probably those in national cloud deployments). If you are an Entra ID admin reading this, yes that means complete access to your tenant. The vulnerability consisted of two components: undocumented impersonation tokens that Microsoft uses in their backend for service-to-service (S2S) communication, called “Actor tokens”, and a critical vulnerability in the (legacy) Azure AD Graph API that did not properly validate the originating tenant, allowing these tokens to be used for cross-tenant access.

That NPM attack could have been so much worse.

A critical vulnerability in Docker Desktop for Windows and macOS allows compromising the host by running a malicious container, even if the Enhanced Container Isolation (ECI) protection is active.

Introduction: when the trust model can’t be trusted Secrets vaults are the backbone of digital infrastructure. They store the credentials, tokens, and certificates that govern access to systems, services, APIs, and data. They’re not just a part of the trust model, they are the trust model. In other words, if your vault is compromised, your […]

CISA says the U.S. government has extended MITRE's funding to ensure no continuity issues with the critical Common Vulnerabilities and Exposures (CVE) program.

The Common Vulnerabilities and Exposures (CVE) Program has become the cornerstone of vulnerability management. Nearly all technology vendors and service providers identify vulnerabilities with CVEs when they publish security advisories. Most security products and services related to vulnerabilities

After DHS did not renew its funding contract for reasons unspecified, MITRE’s 25-year-old Common Vulnerabilities and Exposures (CVE) program was slated for an abrupt shutdown on April 16, which would have left security flaw tracking in limbo. CISA stepped in to provide a bridge.

A new class of supply chain attacks named 'slopsquatting' has emerged from the increased use of generative AI tools for coding and the model's tendency to "hallucinate" non-existent package names.

Critical authentication bypass vulnerabilities were discovered in ruby-saml up to version 1.17.0. See how they were uncovered.

Introduction Hello, I’m RyotaK (@ryotkak ), a security engineer at Flatt Security Inc. A few days ago, I was upgrading my home lab network, and I decided to upgrade the OpenWrt on my router.1 After accessing the LuCI, which is the web interface of OpenWrt, I noticed that there is a section called Attended Sysupgrade, so I tried to upgrade the firmware using it. After reading the description, I found that it states it builds new firmware using an online service.

Google’s Project Zero hackers and DeepMind boffins have collaborated to uncover a zero-day security vulnerability in real-world code for the first time using AI.

No patches yet, can be mitigated, requires user interaction

Critical Unauthenticated RCE Flaw, no Common CVE identifiers have been assigned yet, although experts suggest there should be at least three to six.

Welcome back to another watchTowr Labs blog. Brace yourselves, this is one of our most astounding discoveries.

Download the Writeup Illustration Romain Flamand – Flamingo Studio – [email protected] Abstract Secure elements are small microcontrollers whose main purpose is to generate/store secrets and then execute cryptographic operations. They undergo the highest level of security evaluations that exists (Common Criteria) and are often considered inviolable, even in the worst-case attack scenarios. Hence, complex secure […]
