Enjoy this special encore episode, where we are joined by Jon Williams from Bishop Fox, as he is sharing their research on "It’s 2024 and Over 178,000 SonicWall Firewalls are Publicly Exploitable." SonicWall published advisories for CVE-2022-22274 and CVE-2023-0656 a year apart after finding that NGFW series 6 and 7 devices are affected by two unauthenticated denial-of-service vulnerabilities.
The research states "Our research found that the two issues are fundamentally the same but exploitable at different HTTP URI paths due to reuse of a vulnerable code pattern." They also found that when they scanned SonicWall firewalls with management interfaces exposed to the internet, they found that 76% are vulnerable to one or both issues.

This week, we are joined by, Amnon Kushnir from Sygnia, who is sharing their work on "China-Nexus Threat Group ‘Velvet Ant’ Leverages a Zero-Day to Deploy Malware on Cisco Nexus Switches." In early 2024, Sygnia observed the ‘Velvet Ant’ threat group exploiting a zero-day vulnerability (CVE-2024-20399) to infiltrate Cisco Switch appliances and operate undetected within enterprise networks.
This attack enables threat actors to escape Cisco’s command interface and install malware directly on the device’s OS, bypassing standard security tools. The incident underscores the risks posed by third-party appliances and the importance of enhanced monitoring and threat detection to counter advanced persistent threats.

This week, we are pleased to be joined by Mick Baccio, global security advisor for Splunk SURGe, sharing their research on "LLM Security: Splunk & OWASP Top 10 for LLM-based Applications." The research dives into the rapid rise of AI and Large Language Models (LLMs) that initially seem magical, but behind the scenes, they are sophisticated systems built by humans. Despite their impressive capabilities, these systems are vulnerable to numerous cyber threats.
Splunk's research explores the OWASP Top 10 for LLM Applications, a framework that highlights key vulnerabilities such as prompt injection, training data poisoning, and sensitive information disclosure.

We are joined by Yves Younan, Senior Manager, Talos Vulnerability Discovery and Research from Cisco, discussing their work on "How multiple vulnerabilities in Microsoft apps for macOS pave the way to stealing permissions." Cisco Talos has uncovered eight vulnerabilities in Microsoft applications for macOS that could allow attackers to exploit the system's permission model by injecting malicious libraries.
By leveraging permissions already granted to these apps, attackers could gain access to sensitive resources like the microphone, camera, and screen recording without user consent. While Microsoft considers these issues low risk and has declined to fix them, the vulnerabilities pose a potential threat to user privacy and security.
