    Quishing for trouble.

    Adam Khan, VP of Security Operations at Barracuda, joins to discuss his team's work on "The evolving use of QR codes in phishing attacks." Cybercriminals are evolving phishing tactics by embedding QR codes, or “quishing,” into PDF documents attached to emails, tricking recipients into scanning them to access malicious websites that steal credentials. Barracuda researchers found over half a million such emails from June to September 2024, with most impersonating brands like Microsoft, DocuSign, and Adobe to exploit urgency and trust. To counter these attacks, businesses should deploy multilayered email security, use AI-powered detection tools, educate employees on QR code risks, and enable multifactor authentication to safeguard accounts.

    Watching the watchers. IoT vulnerabilities exposed by AI.

    This week, we are joined by Andrew Morris, Founder and CTO of GreyNoise, to discuss their work on "GreyNoise Intelligence Discovers Zero-Day Vulnerabilities in Live Streaming Cameras with the Help of AI." GreyNoise discovered two critical zero-day vulnerabilities in IoT-connected live streaming cameras, used in sensitive environments like healthcare and industrial operations, by leveraging its AI-powered detection system, Sift. The vulnerabilities, CVE-2024-8956 (insufficient authentication) and CVE-2024-8957 (OS command injection), could allow attackers to take full control of affected devices, manipulate video feeds, or integrate them into botnets for broader attacks. This breakthrough underscores the transformative role of AI in identifying threats that traditional systems might miss, highlighting the urgent need for robust cybersecurity measures in the expanding IoT landscape.

    The JPHP loader breaking away from the pack.

    Shawn Kanady, Global Director of Trustwave SpiderLabs, to discuss their work on "Pronsis Loader: A JPHP-Driven Malware Diverging from D3F@ck Loader." Trustwave SpiderLabs has uncovered Pronsis Loader, a new malware variant using the rare programming language JPHP and stealthy installation tactics to evade detection. The malware is capable of delivering high-risk payloads like Lumma Stealer and Latrodectus, posing a significant threat. Researchers highlight its unique capabilities and infrastructure, offering insights for bolstering cybersecurity defenses.

    Leaking your AWS API keys, on purpose?

    Please enjoy this encore episode: Noah Pack, a SANS Internet Storm Center Intern, sits down to discuss research on "What happens when you accidentally leak your AWS API keys?" This research is a guest diary from Noah and shares a project he worked on after seeing an online video of someone who created a python script that emailed colleges asking for free swag to be shipped to him. The research states "In this article, I will share some research, resources, and real-world data related to leaked AWS API keys." In this research, Noah shares what he learned while implementing his experiment. The research can be found here: What happens when you accidentally leak your AWS API keys?

    Exposing AI's Achilles heel.

    This week, we are joined by Ami Luttwak, Co-Founder and CTO from Wiz, sharing their work on "Wiz Research Finds Critical NVIDIA AI Vulnerability Affecting Containers Using NVIDIA GPUs, Including Over 35 percent of Cloud Environments." A critical vulnerability in the NVIDIA Container Toolkit, widely used for GPU access in AI workloads, could allow attackers to escape containers and gain full access to host environments, jeopardizing sensitive data. Wiz estimates that at least 33% of cloud environments are affected and urges immediate updates to NVIDIA's patched version. This discovery highlights the broader issue of young, under-secured codebases in AI tools, emphasizing the need for stronger security measures and collaboration.

    Credential harvesters in the cloud.

    This week we are joined by, Blake Darché, Head of Cloudforce One at Cloudflare, to discuss their work on "Unraveling SloppyLemming’s Operations Across South Asia." Cloudforce One's investigation into the advanced threat actor "SloppyLemming" reveals an extensive espionage campaign targeting South and East Asia, with a focus on Pakistan's government, defense, telecommunications, and energy sectors. Leveraging multiple cloud service providers, SloppyLemming employs tactics like credential harvesting, malware delivery, and command-and-control (C2) operations, often relying on open-source adversary emulation tools like Cobalt Strike. Despite its activities, the actor's poor operational security (OPSEC) has allowed investigators to gain valuable insights into its infrastructure and tooling.

    A firewall wake up call.

    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.

    Velvet Ant's silent invasion.

    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.
