Piotr Wojtyla, Head of Threat Intel and Platform at Abnormal AI, is discussing their work on "InboxPrime AI: New Phishing Kit Fueling Scalable, AI-Powered Cybercrime." A new AI-powered phishing kit called InboxPrime AI is rapidly gaining traction in underground forums, automating the creation and delivery of highly believable phishing emails that mimic legitimate business communications and leverage Gmail’s web interface to evade detection.

First spotted in October 2025, the kit combines AI-generated content, template variation, sender identity spoofing, and built-in spam checks to maximize inbox placement and dramatically lower the barrier to running large-scale phishing campaigns. Its shift to a one-time $1,000 purchase and growing user base underscore the industrialization of phishing and highlight how quickly AI-driven attack tools are outpacing legacy email defenses.

Muhammad Danish, University of New Mexico lead author and cybersecurity researcher, discussing his team's work on "Private Links, Public Leaks: Consequences of Frictionless User Experience on the Security and Privacy Posture of SMS-Delivered URLs". This paper examines how the push for frictionless user experiences has led many services to rely on SMS-delivered, single-click URLs—an inherently insecure channel that can be intercepted or leaked.

Analyzing more than 322,000 unique URLs from 33 million messages, the researchers found widespread security failures, including exposed PII across 701 endpoints at 177 services due to weak, token-based authentication that treats possession of a link as sufficient authorization. The study also identified low-entropy tokens enabling mass URL enumeration and data overfetching issues, though disclosures prompted 18 services to fix flaws, improving privacy protections for at least 120 million users.

Today we have Andrew Northern, Principal Security Researcher at Censys, discussing "From Evasion to Evidence: Exploiting the Funneling Behavior of Injects". This research explains how modern web malware campaigns use multi-stage JavaScript injections, redirects, and fake CAPTCHAs to selectively deliver payloads and evade detection.

It shows that these attack chains rely on stable redirect and traffic-distribution chokepoints that can be monitored at scale. Using the SmartApe campaign as a case study, the report demonstrates how defenders can turn those chokepoints into high-confidence detection and tracking opportunities.

Today we are joined by Ben Folland, Security Operations Analyst from Huntress, discussing their work on "ClickFix Gets Creative: Malware Buried in Images." This analysis covers a ClickFix campaign that uses fake human verification checks and a realistic Windows Update screen to trick users into manually running malicious commands.

The multi-stage attack chain leverages mshta.exe, PowerShell, and .NET loaders, ultimately delivering infostealers like LummaC2 and Rhadamanthys, with payloads hidden inside PNG images using steganography. While technically sophisticated, the campaign hinges on simple user interaction, underscoring the importance of user awareness and controls around command execution.

This week, we are joined by Martin Zugec, Technical Solutions Director from Bitdefender, sharing their work and findings on "EggStreme Malware: Unpacking a New APT Framework Targeting a Philippine Military Company." Built for long-term espionage, the campaign uses DLL sideloading, in-memory execution, and abused Windows services to stay stealthy and persistent.

We walk through how the multi-stage framework delivers a powerful backdoor with reconnaissance, lateral movement, data theft, and keylogging capabilities—and what this operation reveals about the evolving tactics defenders need to watch for.

Today we are joined by ⁠⁠Selena Larson⁠⁠, co-host of ⁠⁠Only Malware in the Building⁠⁠ and Staff Threat Researcher and Lead Intelligence Analysis and Strategy at ⁠⁠Proofpoint⁠⁠, sharing their work on "Microsoft OAuth App Impersonation Campaign Leads to MFA Phishing." Proofpoint researchers have identified campaigns where threat actors use fake Microsoft OAuth apps to impersonate services like Adobe, DocuSign, and SharePoint, stealing credentials and bypassing MFA via attacker-in-the-middle phishing kits, mainly Tycoon.

These attacks redirect users to fake Microsoft login pages to capture credentials, 2FA tokens, and session cookies, targeting nearly 3,000 Microsoft 365 accounts across 900 environments in 2025. Microsoft’s upcoming security changes and strengthened email, cloud, and web defenses, along with user education, are recommended to reduce these risks.

This week, we are joined by ⁠Tom Hegel⁠, Principal Threat Researcher from ⁠SentinelLabs⁠ research team, to discuss their work on "Ghostwriter | New Campaign Targets Ukrainian Government and Belarusian Opposition." The latest Ghostwriter campaign, linked to Belarusian government espionage, is actively targeting Ukrainian military and government entities as well as Belarusian opposition activists using weaponized Excel documents.

SentinelLabs identified new malware variants and tactics, including obfuscated VBA macros that deploy malware via DLL files, with payload delivery seemingly controlled based on a target’s location and system profile. The campaign, which began preparation in mid-2024 and became active by late 2024, appears to be an evolution of previous Ghostwriter operations, combining disinformation with cyberattacks to further political and military objectives.

Darren Meyer, Security Research Advocate at Checkmarx, is sharing their work on "Bypassing AI Agent Defenses with Lies-in-the-Loop." Checkmarx Zero researchers introduce “lies-in-the-loop,” a new attack technique that bypasses human‑in‑the‑loop AI safety controls by deceiving users into approving dangerous actions that appear benign.

Using examples with AI code assistants like Claude Code, the research shows how prompt injection and manipulated context can trick both the agent and the human reviewer into enabling remote code execution. The findings highlight a growing risk as AI agents become more common in developer workflows, underscoring the limits of human oversight as a standalone security control.

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.
