Microsoft Bolsters Entra ID Defenses Against Script Injection Attacks
Microsoft is stepping up Entra ID security by blocking external script injections, starting mid-October 2026, to shield users from potential threats during sign-ins. This move will ensure only trusted scripts from Microsoft's content delivery network can run during authentication.
Rogue MFA Providers Exploit Entra ID for Password Theft
Security researchers have uncovered a sneaky technique called TrustSink that allows rogue MFA providers to swipe plaintext passwords during seemingly normal login attempts, and they've demonstrated it works with Microsoft Entra ID. This alarming exploit lets attackers get their hands on sensitive passwords, complete with timestamps and source IP addresses.
Identity Infrastructure Exposes Hidden Risks in Active Directory
In today's cybersecurity landscape, identity has become the new perimeter - and Active Directory and Entra ID are the control centers that keep it all connected, making them prime targets for attackers. Compromising these identity infrastructures can give hackers access to an entire environment, not just a single system.
Microsoft Urges Admins to Migrate Entra ID Users to Phishing-Resistant Auth Methods
Microsoft is sounding the alarm: by February 1, 2027, admins must migrate Entra ID users to phishing-resistant auth methods, as the company will retire SMS and voice authentication, leaving users vulnerable to cyber threats if they don't make the switch.
Public Sector Braces for Identity-Based Attacks
In today's digital landscape, your identity is the key that unlocks access to all your applications and services - making it the new perimeter that public sector organizations must fiercely protect. When identity infrastructure is compromised, attackers can gain a foothold for long-term persistence and privilege escalation, putting entire operations at risk.
Passkey Defenses Targeted in Novel Attacks
Researchers at Black Hat USA 2026 revealed a shocking vulnerability in passkey defenses, demonstrating how attackers can bypass FIDO2 cryptography and exploit a flaw in Windows Event Logging Service (CVE-2026-34348) to defeat passkey protections. This security gap was found to allow unauthorized users to access and replay sensitive YubiKey signatures.
Malware Exploits Windows Hello for Business Keys to Gain Persistent Entra ID Access
Malware can quietly hijack your Windows Hello for Business key to gain long-term access to your Entra ID account, allowing hackers to register a new device and add extra authentication methods. To stay safe, Entra ID researcher Dirk‑jan Mollema advises monitoring unexpected device registrations.
NSA, CISA Warn Federal Agencies of Identity Security Risks
The NSA and CISA are sounding the alarm: identity security risks are now the frontline in federal cybersecurity, with Active Directory and Entra ID being prime targets for cyber attackers. Recent incidents show that nearly 75% of major federal cyber breaches in the last five years involved compromised identities.
Varonis Launches Breach at the Beach, a Hands-On Entra ID Training Experience
Get ready to dive into the world of Entra ID with Varonis' immersive Breach at the Beach training experience, where you'll learn to navigate the complex control plane that connects users, applications, and AI-powered workflows. Discover how to defend against threats that exploit non-human identities and automate breaches.
Nation-State Actors Exploit ROADtools in Cloud Attacks
Cloud attackers are now leveraging ROADtools, a publicly available toolkit, to exploit vulnerabilities in cloud tenants, allowing them to persist, discover, and evade defenses with ease. This dual-use framework's ability to speak Entra ID and Microsoft Graph makes it a red flag for defenders to take notice.
Microsoft Vulnerabilities Spike in Critical Areas
A single critical flaw, like CVE-2025-55241, can give attackers unrestricted access to any tenant, highlighting the alarming rise in critical Microsoft vulnerabilities, which doubled in 2025 despite a stable overall number of vulnerabilities. This sharp increase in high-impact weaknesses demands attention and action.
Active Directory Breaches Persist After Password Resets
Resetting passwords isn't enough to keep hackers at bay, especially in Active Directory environments where cached credentials and sync delays can leave gaping security holes. Even after a password reset, attackers can still find ways to exploit outdated credentials and gain unauthorized access.
Microsoft Fixes Entra ID Flaw That Enabled Service Principal Takeovers
Microsoft has patched a vulnerability in Entra ID that allowed hackers to hijack service principals, potentially leading to full takeover of sensitive systems. A security researcher discovered the flaw, which stemmed from overly broad permissions in the Agent ID Administrator role.
Microsoft Graph API Change Disrupts Universal Print Sharing
Microsoft revealed that a recent code change to the Microsoft Graph API caused a ripple effect, introducing a critical error that disrupted Universal Print sharing and left many users in a frustrating limbo. The error sparked a chain reaction, exposing a long-standing issue that prevented share operations from completing as expected.
