Microsoft Flags Multi-Stage AitM Phishing in Energy Sector

🔒 Microsoft warns of a multi-stage adversary-in-the-middle (AitM) phishing and BEC campaign targeting the energy sector. The attackers abused SharePoint file-sharing and legitimate trusted addresses (a living-off-trusted-sites, LOTS, technique) to deliver credential-harvesting links, then used stolen session cookies and inbox rules to persist and hide activity. Microsoft says simple password resets are insufficient; organizations must revoke sessions, remove malicious rules, and enforce phishing-resistant controls.

Malicious Google Chrome Extensions Hijack Workday and Netsuite

🔒 Security researchers at Socket have identified a set of malicious Google Chrome extensions that targeted major HR and ERP platforms including Workday, Netsuite and SAP SuccessFactors. The extensions, which masqueraded as productivity tools, stole authentication cookies and session tokens, uploading them to a command-and-control server and revisiting targets every 60 seconds. More than 2,300 users downloaded the extensions from the Chrome Web Store before they were removed. Socket recommends using Chrome Enterprise extension allowlists and monitoring for extensions with similar platform targeting and permission requests.

Malicious Chrome extensions hijack enterprise sessions

🔒 A cluster of five malicious Chrome extensions posed as productivity tools but exfiltrated session cookies to attacker-controlled infrastructure, enabling account takeover. Researchers from Socket.dev identified variants such as DataByCloud Access, Data By Cloud 1/2, Software Access and Tool Access 11 targeting HR and ERP platforms like Workday, NetSuite and SuccessFactors. Some extensions stole cookies as often as every 60 seconds and used cookie injection (e.g., chrome.cookies.set()) while others blocked admin security pages, hampering incident response.

Credential-stealing Chrome extensions target HR platforms

🔒 Socket discovered malicious Chrome extensions on the Web Store that mimicked productivity and security tools for enterprise HR and ERP systems and had been installed over 2,300 times. The five extensions targeted Workday, NetSuite, and SAP SuccessFactors, employing cookie exfiltration, DOM manipulation to block admin pages, and cookie injection to enable session hijacking. Google removed the extensions after notification; affected users should report use to administrators, perform incident response, and change credentials on impacted platforms.

Reprompt Attack Could Hijack Microsoft Copilot Sessions

⚠️ Security researchers at Varonis disclosed a vulnerability, dubbed Reprompt, that could let attackers hijack a user's Copilot Personal session by embedding malicious instructions in a URL. The attack leverages the 'q' URL parameter to inject prompts that execute when the page loads, then uses chained server-side follow-up requests to maintain access and exfiltrate data after a single click. Varonis reported the issue to Microsoft on August 31, and Microsoft issued a fix on the January 2026 Patch Tuesday; users should apply the latest Windows update promptly.

YoSmart YoLink Vulnerabilities Affect Server, Hub, App

🔒 CISA reported several vulnerabilities in the YoSmart YoLink ecosystem impacting the cloud server, Smart Hub, and mobile application. Exploitation could let attackers remotely control other users' devices, intercept unencrypted MQTT traffic, and hijack sessions. YoSmart pushed server-side fixes and will deliver a hub firmware update over-the-air; users should update the YoLink mobile app to 1.40.45 or later.

Open WebUI SSE Flaw Allows Malicious Model Server Takeover

⚠ Security researchers at Cato Networks disclosed CVE-2025-64496, a vulnerability in Open WebUI that lets external model servers inject JavaScript via Server-Sent Events (SSE) when the Direct Connections feature is enabled. An attacker controlling a malicious model endpoint can exfiltrate JSON Web Tokens (JWTs) from the browser, enabling account takeover and access to documents, chats, and embedded API keys. If the compromised account has Workspace Tools privileges, the session token can be used to execute authenticated Python code on the backend, leading to remote code execution. The flaw affects versions up to 0.6.34 and is fixed in 0.6.35; organizations are urged to update and implement HttpOnly cookies, strict CSPs, and ban dynamic code evaluation.

When Browsers Become the Attack Surface: Rethinking Security

🔒 As enterprises shift more critical work to the browser, adversary Scattered Spider (UNC3944) targets live browser data—saved credentials, calendars, and session tokens—to achieve account takeover and persistent access. The article highlights techniques like Browser-in-the-Browser overlays, JavaScript injection, malicious extensions, and token theft that evade conventional EDR. It recommends elevating browser-native controls: runtime JavaScript protection, session-token binding, extension governance, API restrictions, and integrated browser telemetry so CISOs treat browser security as a primary defense layer.
