When macOS gets frostbite.

Daniel Schwalbe, DomainTools Head of Investigations and CISO, is sharing their work on "Inside the Great Firewall." This two-part research project analyzes an extraordinary 500–600GB leak that exposes the internal architecture, tooling, and human ecosystem behind China’s Great Firewall. Across both parts, you break down thousands of leaked documents, source code repositories, diagrams, packet captures, and telemetry that reveal how systems like the Traffic Secure Gateway, MAAT, Redis-based analytics, and modular DPI engines work together to censor, surveil, and fingerprint users at scale. Taken together, the research shows how the Great Firewall functions not just as a technical system, but as a living censorship-industrial complex that adapts, learns, and coordinates across government, telecoms, and security vendors.

Jaron Bradley, Director of Jamf Threat Labs, is sharing their work on "ChillyHell: A Deep Dive into a Modular macOS Backdoor." Jamf Threat Labs uncovers a newly notarized macOS backdoor called ChillyHell, tied to past UNC4487 activity and disguised as a legitimate applet. The malware showcases robust host profiling, multiple persistence mechanisms, timestomping, and flexible C2 communications over both DNS and HTTP. Its modular design includes reverse shells, payload delivery, self-updates, and a brute-force component targeting user credentials.

Please enjoy this encore of Research Saturday. This week, we are joined by ⁠Michael Gorelik⁠, Chief Technology Officer from ⁠Morphisec⁠, discussing their work on "New Noodlophile Stealer Distributes Via Fake AI Video Generation Platforms." A new threat dubbed Noodlophile Stealer is exploiting the popularity of AI-powered content tools by posing as fake AI video generation platforms, luring users into uploading media in exchange for malware-laced downloads. Distributed through convincing Facebook groups and viral campaigns, the malware steals browser credentials, cryptocurrency wallets, and can deploy a remote access trojan like XWorm. The campaign uses a layered, obfuscated delivery chain disguised as legitimate video editing software, making it both deceptive and difficult to detect.

Alex Berninger, Senior Manager of Intelligence at Red Canary, and Mike Wylie, Director, Threat Hunting at Zscaler, join to discuss four phishing lures in campaigns dropping RMM tools. Red Canary and Zscaler uncovered phishing campaigns delivering legitimate remote monitoring and management (RMM) tools—like ITarian, PDQ, SimpleHelp, and Atera—to gain stealthy access to victim systems. Attackers used four main lures (fake browser updates, meeting invites, party invitations, and fake government forms) and often deployed multiple RMM tools in quick succession to establish persistent access and deliver additional malware. The report highlights detection opportunities, provides indicators of compromise, and stresses the importance of monitoring authorized RMM usage, scrutinizing trusted services like Cloudflare R2, and enforcing strict network and endpoint controls.

Dr. Renée Burton, Vice President of Threat Intelligence from Infoblox, is sharing the team's work on "Deniability by Design: DNS-Driven Insights into a Malicious Ad Network." Infoblox returns with new threat actor research uncovering Vane Viper, a Cyprus-based holding company behind PropellerAds—one of the world’s largest advertising networks. The report reveals that Vane Viper isn’t just being exploited by criminals but operates as a criminal infrastructure itself, built to profit from fraud, malware, and disinformation through offshore entities and complex ownership structures. The findings highlight the growing convergence between adtech, cybercrime, and state-linked influence operations, suggesting that elements of the global digital advertising ecosystem are now functioning as infrastructure for large-scale cyber and disinformation campaigns.

Tal Peleg, Senior Product Manager, and Coby Abrams, Cyber Security Researcher of Varonis, discussing their work and findings on Rusty Pearl - Remote Code Execution in Postgres Instances. The flaw could allow attackers to execute arbitrary commands on a database server’s operating system, leading to potential data theft, destruction, or lateral movement across networks. While the vulnerability existed in PostgreSQL, Amazon RDS and Aurora were not affected, thanks to built-in protections like SELinux and AWS’s automated threat detection. Still, the research underscores the importance of patching and configuration hygiene in managed database environments.

Today we are joined by Dario Pasquini, Principal Researcher at RSAC, sharing the team's work on WhenAIOpsBecome “AI Oops”: Subverting LLM-driven IT Operations via Telemetry Manipulation. A first-of-its-kind security analysis showing that LLM-driven AIOps agents can be tricked by manipulated telemetry, turning automation itself into a new attack vector. The researchers introduce AIOpsDoom, an automated reconnaissance + fuzzing + LLM-driven telemetry-injection attack that performs “adversarial reward-hacking” to coerce agents into harmful remediations—even without prior knowledge of the target and even against some prompt-defense tools. They also present AIOpsShield, a telemetry-sanitization defense that reliably blocks these attacks without harming normal agent performance, underscoring the urgent need for security-aware AIOps design.

Noam Moshe, Claroty’s Vulnerability Research Team Lead, joins Dave to discuss Team 82's work on "Turning Camera Surveillance on its Axis." Team82 disclosed four vulnerabilities in Axis.Remoting—deserialization, a MiTM “pass-the-challenge” NTLMSSP flaw, and an unauthenticated fallback HTTP endpoint—that enable pre-auth remote code execution against Axis Device Manager and Axis Camera Station. They found more than 6,500 Axis.Remoting services exposed online (over half in the U.S.), letting attackers enumerate targets, install malicious Axis packages, and hijack, view, or shut down managed camera fleets.Axis published an urgent advisory, issued patches for ADM 5.32, Camera Station 5.58 and Camera Station Pro 6.9, accepted Team82’s disclosure, and organizations are urged to update.

Eclypsium researchers Jesse Michael and Mickey Shkatov to share their work on "BadCam - Now Weaponizing Linux Webcams." Eclypsium researchers disclosed “BadCam,” a set of vulnerabilities in certain Lenovo USB webcams that run Linux and do not validate firmware signatures, allowing attackers to reflash the devices and turn them into BadUSB-style tools. An adversary who supplies a backdoored camera or who gains remote code execution on a host can weaponize the webcam to emulate human-interface devices, inject keystrokes, deliver payloads, and maintain persistence — even re-infecting systems after OS reinstalls. The findings were presented at DEF CON 2025, Lenovo issued updated firmware/tools in coordination with SigmaStar, and researchers warn the same vector could affect other Linux-based USB peripherals, underscoring the need for firmware signing and stronger device attestation.

John Fokker, Head of Threat Intelligence at Trellix is discussing "Gang Wars: Breaking Trust Among Cyber Criminals." Trellix researchers reveal how the once-organized ransomware underworld is collapsing under its own paranoia. Once united through Ransomware-as-a-Service programs, gangs are now turning on each other — staging hacks, public feuds, and exit scams as trust evaporates. With affiliates jumping ship and rival crews sabotaging each other, the RaaS model is fracturing fast, signaling the beginning of the end for ransomware’s criminal empires.
