Threat actors are luring unsuspecting users with free or pirated versions of commercial software to deliver a malware loader called Hijack Loader , which then deploys an information stealer known as Vidar Stealer . "Adversaries had managed to trick users into downloading password-protected archive files containing trojanized copies of a Cisco Webex Meetings App (ptService.exe)," Trellix security researcher Ale Houspanossian said in a Monday analysis. "When unsuspecting victims extracted and executed a 'Setup.exe' binary file, the Cisco Webex Meetings application covertly loaded a stealthy malware loader, which led to the execution of an information-stealing module." The starting point is a RAR archive file that contains an executable name "Setup.exe," but in reality is a copy of Cisco Webex Meetings's ptService module. What makes the campaign noteworthy is the use of DLL side-loading techniques to stealthily launch Hijack Loader (aka DOI...

After Equifax massive data breach that was believed to be caused due to a vulnerability in Apache Struts , Cisco has initiated an investigation into its products that incorporate a version of the popular Apache Struts2 web application framework. Apache Struts is a free, open-source MVC framework for developing web applications in the Java programming language, and used by 65 percent of the Fortune 100 companies, including Lockheed Martin, Vodafone, Virgin Atlantic, and the IRS. However, the popular open-source software package was recently found affected by multiple vulnerabilities, including two remote code execution vulnerabilities—one discovered earlier this month, and another in March—one of which is believed to be used to breach personal data of over 143 million Equifax users . Some of Cisco products including its Digital Media Manager, MXE 3500 Series Media Experience Engines, Network Performance Analysis, Hosted Collaboration Solution for Contact Center, and Unified C...

A highly critical vulnerability has been discovered in the Cisco Systems' WebEx browser extension for Chrome and Firefox, for the second time in this year, which could allow attackers to remotely execute malicious code on a victim's computer. Cisco WebEx is a popular communication tool for online events, including meetings, webinars and video conferences that help users connect and collaborate with colleagues around the world. The extension has roughly 20 million active users. Discovered by Tavis Ormandy of Google Project Zero and Cris Neckar of Divergent Security, the remote code execution flaw (CVE-2017-6753) is due to a designing defect in the WebEx browser extension. To exploit the vulnerability, all an attacker need to do is trick victims into visiting a web page containing specially crafted malicious code through the browser with affected extension installed. Successful exploitation of this vulnerability could result in the attacker executing arbitrary code with th...

Security Service Edge (SSE) platforms have become the go-to architecture for securing hybrid work and SaaS access. They promise centralized enforcement, simplified connectivity, and consistent policy control across users and devices. But there's a problem: they stop short of where the most sensitive user activity actually happens—the browser. This isn't a small omission. It's a structural limitation. And it's leaving organizations exposed in the one place they can't afford to be: the last mile of user interaction. A new report Reevaluating SSEs: A Technical Gap Analysis of Last-Mile Protection analyzing gaps in SSE implementations reveals where current architectures fall short—and why many organizations are reevaluating how they protect user interactions inside the browser. The findings point to a fundamental visibility challenge at the point of user action. SSEs deliver value for what they're designed to do—enforce network-level policies and route traffic securely between en...
