Enterprise-grade Juniper Networks routers have become the target of a custom backdoor as part of a campaign dubbed J-magic . According to the Black Lotus Labs team at Lumen Technologies, the activity is so named for the fact that the backdoor continuously monitors for a "magic packet" sent by the threat actor in TCP traffic.  "J-magic campaign marks the rare occasion of malware designed specifically for Junos OS, which serves a similar market but relies on a different operating system, a variant of FreeBSD," the company said in a report shared with The Hacker News. Evidence gathered by the company shows that the earliest sample of the backdoor dates back to September 2023, with the activity ongoing between mid-2023 and mid-2024. Semiconductor, energy, manufacturing, and information technology (IT) sectors were the most targeted. Infections have been reported across Europe, Asia, and South America, including Argentina, Armenia, Brazil, Chile, Colombia, Indone...

Zyxel has released software updates to address a critical security flaw impacting certain access point (AP) and security router versions that could result in the execution of unauthorized commands. Tracked as CVE-2024-7261 (CVSS score: 9.8), the vulnerability has been described as a case of operating system (OS) command injection. "The improper neutralization of special elements in the parameter 'host' in the CGI program of some AP and security router versions could allow an unauthenticated attacker to execute OS commands by sending a crafted cookie to a vulnerable device," Zyxel said in an advisory. Chengchao Ai from the ROIS team of Fuzhou University has been credited with discovering and reporting the flaw. Zyxel has also shipped updates for eight vulnerabilities in its routers and firewalls, including few that are high in severity, that could result in OS command execution, a denial-of-service (DoS), or access browser-based information - CVE-2024...

Are you tired of dealing with outdated security tools that never seem to give you the full picture? You're not alone. Many organizations struggle with piecing together scattered information, leaving your apps vulnerable to modern threats. That's why we're excited to introduce a smarter, unified approach: Application Security Posture Management (ASPM). ASPM brings together the best of both worlds by connecting your code insights with real-time runtime data. This means you get a clear, holistic view of your application's security. Instead of reacting to threats, ASPM helps you prevent them. Imagine reducing costly retrofits and emergency patches with a proactive, shift-left strategy—saving you time, money, and stress. Join Amir Kaushansky, Director of Product Management at Palo Alto Networks, as he walks you through how ASPM is changing the game. In this free webinar , you'll learn to: Close the Security Gaps: Understand why traditional AppSec tools fall short and how ASPM fills ...
