SOAPHound's LDAP query (!soaphound=*) never appears in Event 1644 logs, but it transforms into (! (FALSE)) through LDAP optimization. Understanding this transformation reveals a unique detection signature that most defenders have never seen.
This blog uncovers DeadLock’s stealthy usage of Polygon smart contracts for proxy address storage, a poorly-documented and under-reported technique that Group-IB analysts have observed increased usage in the wild. Variants of this technique are very wide and offer great alternatives to threat actors for bypassing traditional defenses by abusing decentralized blockchains available worldwide.
Huntress researchers weigh in on the challenge of getting feature parity across Windows, macOS, and Linux. And learn how unique security models and platform maturity shape the way products are built.

One year from now, with the release of Chrome 154 in October 2026, we will change the default settings of Chrome to enable “Always Use Secure Connections”. This means Chrome will ask for the user's permission before the first access to any public site without HTTPS. The “Always Use Secure Connections” setting warns users before accessing a site without HTTPS Chrome Security's mission is to make it safe to click on links. Part of being safe means ensuring that when a user types a URL or clicks o…
Huntress has observed threat actors exploiting a Microsoft Windows Server Update Services (WSUS) vulnerability (CVE-2025-59287).
In today’s sprawling digital landscape, the question for security leaders isn’t whether Attack Surface Management (ASM) matters; it’s whether your ASM platform is doing enough to earn its place in the budget. If your board or finance team is asking you to justify the spend, you’re not alone. Saying it “improves visibility” or “reduces risk” isn’t enough anymore. You need to show real outcomes, saved hours, reduced incidents, lower cloud costs, and stronger operational resilience. That’s where C…
Posted by Elie Bursztein and Marianna Tishchenko, Google Privacy, Safety and Security TeamEmpowering cyber defenders with AI is critical to tilting the cybersecurity balance back in their favor as they battle cybercriminals and keep users safe. To help accelerate adoption of AI for cybersecurity workflows, we partnered with Airbus at DEF CON 33 to host the GenSec Capture the Flag (CTF), dedicated to human-AI collaboration in cybersecurity. Our goal was to create a fun, interactive environment, …
1. Introduction The vibe coding revolution has empowered millions to build and deploy websites using natural languages. Entrepreneurs, artists, and small businesses can now bring their ideas to life online without writing a single line of code. But has this convenience come at a hidden security cost? In this post, we present the 15th wave of Project Resonance: A RedHunt Labs Research Initiative, investigating the security posture of websites built on modern “vibe coding” platforms. Our research…
A critical vulnerability discovered in Microsoft's Entra ID (formerly Azure AD) allowed for cross-tenant access and potential global admin privilege escalation. The flaw was found in the legacy Azure AD Graph API, which improperly validated the originating tenant for undocumented "Actor tokens." An attacker could use a token from their own tenant to authenticate as any user, including Global Admins, in any other tenant. This vulnerability bypassed security policies like Conditional Access. The …
Don’t fall for common Microsoft 365 identity security myths. Here, Huntress debunks misconceptions around logins, MFA, Conditional Access, Impossible Travel, and security tuning.
This blog describes attacks on victims in Central Asia and APAC. Research into the attack has identified a group also called YoroTrooper. We also identified profiles of attackers on hacker forums, their malicious web-panels, test infections of attackers' own machines, and screenshots of attackers' desktops.

Scams like Classiscam automate fake websites to steal financial data, exploiting digitalization’s rise in developing countries, making fraud both effective and hard to detect. In this blog, we dissect the inner working of the scam and its prevalence in Central Asia.
A bug in Entra ID restricted management administrative units allowed creating immutable users that couldn't be modified or disabled, even by Global Administrators. This could enable an attacker to protect a compromised account from containment. The issue was caused by a timing vulnerability when removing users from restricted AUs and required specific steps to remediate affected accounts.
