The security researcher known as Chaotic Eclipse (aka INFINITE NIGHTMARE, MSNightmare, and Nightmare-Eclipse) has dropped a new zero-day dubbed FalconFlank , a proof-of-concept (PoC) for a privilege escalation flaw impacting Crowdstrike Falcon. "FalconFlank is a 0-day privilege escalation that abuses the office malicious macros remediation in CrowdStrike Falcon Sensor," the researcher said in a GitHub README file, adding the cybersecurity company may already have detections for the flaw by now. "So if you want to test, you either have to add it to the exclusions or obfuscate the PoC and change the DLL load technique." The PoC, the researcher added, works in a fully updated Windows 11 25H2 machine or Windows Server 2025 with CrowdStrike Falcon. In a statement shared with The Hacker News, a CrowdStrike spokesperson said they are currently investigating the report. "We are actively investigating these claims and advise customers to disable the Microsof...

A recent wave of cyber attacks targeting financial services, private equity, and professional services has been attributed to a data extortion group known as UNC6671 . "UNC6671 continues to rely on voice phishing (vishing) to target enterprise employees, posing as IT help desk staff facilitating mandatory, urgent security migrations. Significantly, the threat actor often contacts employees via their personal mobile devices," Google Threat Intelligence Group (GTIG) and Mandiant said in a report. These calls are designed to trick victims into spoofed login portals where adversary-in-the-middle (AitM) infrastructure intercepts credentials and multi-factor authentication (MFA) tokens. The threat actors then leverage the captured data to establish session persistence and deploy automated Python and PowerShell scripts for data exfiltration from enterprise cloud environments and SaaS applications, including Microsoft 365 and Okta. According to the tech giant, UNC6671 has d...

The security researcher known as Chaotic Eclipse has dropped a proof-of-concept (PoC) for yet another zero-day in Microsoft Defender. The vulnerability, codenamed ShieldCrash , is assessed to be a patch bypass for CVE-2026-69414 (CVSS score: 7.8), also called ShieldBreak , which the researcher reported last month. "Microsoft has failed to properly patch ShieldBreak CVE-2026-69414," Chaotic Eclipse said. "Under specific conditions it is still possible to trigger the exact same problem that was caused by ShieldBreak. While Microsoft fixed several things to prevent re-exploiting the issue, they missed a spot where ShieldBreak can still be exploited." The PoC demonstrates an arbitrary file read as SYSTEM with the latest version of Windows installed. All supported versions of the desktop operating system are said to be impacted. The development comes days after Redmond shipped an update to the Microsoft Malware Protection Engine to plug CVE-2026-69414. The issue...

Identity visibility is a starting point for modern identity security, because stolen and misused credentials are among the most frequently reported initial access vectors in breach research, including Verizon's annual Data Breach Investigations Report . This article explains what identity visibility means in IAM, why cloud and multicloud environments complicate it, which capabilities matter in identity visibility tools , and how to build a practical program. What is identity visibility? Identity visibility is the ability to see every identity in an environment, what it can access, and how that access is actually used at runtime. It combines inventory, entitlement mapping, and behavioral telemetry into one continuous picture instead of a periodic snapshot. The important distinction is between intent and execution. Identity and access management (IAM) platforms express policy intent: who should have access, under what conditions, and for how long. Applications and infrastructu...
