The threat actor known as EncryptHub is continuing to exploit a now-patched security flaw impacting Microsoft Windows to deliver malicious payloads. Trustwave SpiderLabs said it recently observed an EncryptHub campaign that brings together social engineering and the exploitation of a vulnerability in the Microsoft Management Console (MMC) framework (CVE-2025-26633, aka MSC EvilTwin ) to trigger the infection routine via a rogue Microsoft Console (MSC) file. "These activities are part of a broad, ongoing wave of malicious activity that blends social engineering with technical exploitation to bypass security defenses and gain control over internal environments," Trustwave researchers Nathaniel Morales and Nikita Kazymirskyi said . EncryptHub, also tracked as LARVA-208 and Water Gamayun, is a Russian hacking group that first gained prominence in mid-2024. Operating at a high tempo, the financially motivated crew is known for leveraging several methods, including fake job of...

Cisco has released security updates to address a maximum-severity security flaw in Secure Firewall Management Center (FMC) Software that could allow an attacker to execute arbitrary code on affected systems. The vulnerability, assigned the CVE identifier CVE-2025-20265 (CVSS score: 10.0), affects the RADIUS subsystem implementation that could permit an unauthenticated, remote attacker to inject arbitrary shell commands that are executed by the device. The networking equipment major said the issue stems from a lack of proper handling of user input during the authentication phase, as a result of which an attacker could send specially crafted input when entering credentials that get authenticated at the configured RADIUS server. "A successful exploit could allow the attacker to execute commands at a high privilege level," the company said in a Thursday advisory. "For this vulnerability to be exploited, Cisco Secure FMC Software must be configured for RADIUS authentica...

Multiple HTTP/2 implementations have been found susceptible to a new attack technique called MadeYouReset that could be explored to conduct powerful denial-of-service (DoS) attacks. "MadeYouReset bypasses the typical server-imposed limit of 100 concurrent HTTP/2 requests per TCP connection from a client. This limit is intended to mitigate DoS attacks by restricting the number of simultaneous requests a client can send," researchers Gal Bar Nahum, Anat Bremler-Barr, and Yaniv Harel said . "With MadeYouReset, an attacker can send many thousands of requests, creating a denial-of-service condition for legitimate users and, in some vendor implementations, escalating into out-of-memory crashes." The vulnerability has been assigned the generic CVE identifier, CVE-2025-8671, although the issue impacts several products, including Apache Tomcat ( CVE-2025-48989 ), F5 BIG-IP ( CVE-2025-54500 ), and Netty ( CVE-2025-55163 ). MadeYouReset is the latest flaw in HTTP/2 after ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added two security flaws impacting N-able N-central to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation.  N-able N-central is a Remote Monitoring and Management (RMM) platform designed for Managed Service Providers (MSPs), allowing customers to efficiently manage and secure their clients' Windows, Apple, and Linux endpoints from a single, unified platform. The vulnerabilities in question are listed below - CVE-2025-8875 (CVSS score: N/A) - An insecure deserialization vulnerability that could lead to command execution CVE-2025-8876 (CVSS score: N/A) - A command injection vulnerability via improper sanitization of user input Both shortcomings have been addressed in N-central versions 2025.3.1 and 2024.6 HF2 released on August 13, 2025. N-able is also urging customers to make sure that multi-factor authentication (MFA) is enabled, particularly for admin...

Zoom and Xerox have addressed critical security flaws in Zoom Clients for Windows and FreeFlow Core that could allow privilege escalation and remote code execution.  The vulnerability impacting Zoom Clients for Windows, tracked as CVE-2025-49457 (CVSS score: 9.6), relates to a case of an untrusted search path that could pave the way for privilege escalation. "Untrusted search path in certain Zoom Clients for Windows may allow an unauthenticated user to conduct an escalation of privilege via network access," Zoom said in a security bulletin on Tuesday. The issue, reported by its own Offensive Security team, affects the following products - Zoom Workplace for Windows before version 6.3.10 Zoom Workplace VDI for Windows before version 6.3.10 (except 6.1.16 and 6.2.12) Zoom Rooms for Windows before version 6.3.10 Zoom Rooms Controller for Windows before version 6.3.10 Zoom Meeting SDK for Windows before version 6.3.10 The disclosure comes as multiple vulnerabiliti...
