    Device Code, OAuth, PhaaS: How Session Token Theft is Breaking the Phishing Playbook

    Your user clicked a link, landed on a real Microsoft login page, typed their password, completed MFA, and walked away thinking nothing happened. Somewhere across the internet, an attacker's device just received an authenticated session token. The password is irrelevant. The MFA prompt already fired and passed. With PhaaS platforms now converging on token-theft tradecraft and post-compromise automation executing in seconds, defenders are racing a scripted attacker with a manual playbook. Join hosts Brandon and John as they discuss: How device code phishing uses real authentication infrastructure to capture valid session tokensHow one campaign hit 35,000+ users across 13,000+ organizations in 26 countriesWhy rogue device registrations complete before the average analyst reads the alert Two questions your organization should be asking right now: Has your Conditional Access policy been reviewed specifically for device code grant flows, not whether CA policies exist, but whether they cover the OAuth flows that session-token theft actually exploits?When a phishing confirmation fires, how many manual steps stand between that alert and full token revocation with rogue device deregistration, and is that response faster than the attacker's automation?Resources: https://linktr.ee/ReliaQuestShadowTalk Brandon Tirado: Director of GreyMatter Operations for ReliaQuest. A skilled cyber defense professional with a unique combination of management and hands-on experience. With a deep understanding of adversary motives and the tactics, techniques, and procedures (TTPs) they use to achieve their goals, Brandon enjoys operationalizing his knowledge to make it more difficult for adversaries to operate within the environments of ReliaQuest customers. His managerial and hands-on experience enriches ShadowTalk with practical and strategic viewpoints.

    SQLite, Mistral, OpenAI: How AI Attacks Are Reshaping the Attack Surface

    What happens when an AI agent uncovers a zero-day in hours instead of weeks, and state-backed groups are already operationalizing the same tools? With self-hosted AI infrastructure sprawling outside asset registers and supply chain worms reaching inside AI vendors themselves, defenders need a new operating model. Join hosts Tehman and John as they discuss:  How an AI agent surfaced a memory-safety zero-day in SQLiteHow Mini Shai-Hulud reached Mistral AI and OpenAI devicesWhy the intel-to-action chain still runs at multi-day tempoTwo questions your organization should be asking right now: Do you have visibility into the shadow AI infrastructure, self-hosted models, and inference endpoints sitting unauthenticated on your network?When high-confidence intel lands, what's your median time from "advisory published" to "response action executed"?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    Akira, ShinyHunters, and The Gentlemen: Extortion Lessons From Early 2026

    What factors have driven the top ransomware and extortion groups' success in early 2026? And how should organizations structure their defenses to protect against them? Join hosts Alexandra and John as they discuss: How Akira is exploiting unknown assets inherited through M&AWhy ShinyHunters' vishing and SaaS misconfiguration models workHow The Gentlemen grew 588% quarter-over-quarter Two questions your organization should be asking right now: Have you run a full asset discovery sweep on every environment inherited through acquisition in the last few years?Do you have automated containment rules in place for anomalous MFA device enrollment and EDR-killing behavior?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    What Happened to Black Basta's Playbook? The Automated Teams Phishing Threat Hitting Executives

    Black Basta disbanded in February 2025, but their playbook didn't go with them. In March 2026, 77% of observed incidents targeted executives and directors, and attackers moved from first contact to malicious script execution in as little as 12 minutes. The tactic has been automated, refined, and is now running faster than most SOCs can respond.  Join hosts Alexandra and John as they discuss: How attackers leverage Microsoft Teams phishing to target high-privilege accounts with alarming speedWhy automation is compressing attack timelines and sharpening target selectionThe controls that can stop it, from help desk verification to automated containment workflows Two questions your organization should be asking right now: When IT requests remote access to a senior leader's endpoint, is identity verified through a channel separate from the one the request came from?Do your highest-privilege accounts have dedicated automated containment workflows — or are they the gap in your response playbook?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    Did ShinyHunters Compromise Vercel? Every CISO's Cloud Security Visibility Problem
