    DPRK Insider Threats: How Remote-Worker Tactics Are Evolving

    Security leaders should be asking a hard question: if a remote hire looks legitimate at every checkpoint, what would expose the operation?

    Fake NDAs, Real Money: Inside the M&A Social Engineering Playbook

    In this episode, we examine the Phantom Deal campaign, in which threat actors used publicly available details about companies’ acquisition histories, subsidiaries, executives, and employees to create convincing fake M&A scenarios. The goal: persuade employees to initiate large financial transfers while keeping conversations off corporate communication channels. We also cover a recent series of zero-day disclosures affecting major endpoint-security and Windows products. These vulnerabilities reinforce a critical operational reality: organizations must be prepared to detect and respond even when endpoint-security visibility is weakened or unavailable. Two questions your organization should be asking right now: If an employee received an urgent, confidential payment request from an apparent executive, could they independently verify the request without using the communication channel chosen by the attacker?If an endpoint-security tool went blind during an attack, what identity, network, cloud, and Windows telemetry could your team use to detect and contain the activity?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    From Vulnerability Research to Domain Admin in Minutes

    AI is changing the economics of cyberattacks. In this episode, we examine how a suspected threat actor used AI agents to accelerate PaperCut vulnerability research, exploit development, target identification, and post-compromise activity—moving from initial access to domain administrator access in as little as seven minutes. We also explore recent reporting on large-scale AI-model distillation campaigns by China-based companies and what the increasing availability of frontier-level AI capabilities could mean for future nation-state and criminal threat operations. Two questions your organization should be asking right now: If an attacker gained initial access through an internet-facing system tomorrow, could your team detect and contain the activity in less than seven minutes?Are you evaluating vulnerabilities, exposed services, and identity privileges as connected attack paths—or as separate security issues?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    One Empty Field: The Email Security Bypass Letting Attackers Impersonate Your Executives

    Organizations rely on Microsoft 365's RejectDirectSend control to block internal email spoofing—but a structural gap lets attackers walk right past it. With nothing more than a basic Python script and an empty envelope sender, threat actors are impersonating executives, IT support, and finance teams to launch Business Email Compromise, payment fraud, and follow-on account takeover. Join hosts Alexandra Moore and John Dilgen as they discuss: How an empty email header field bypasses RejectDirectSend and lands phishing in executive inboxesHow help desk impersonation combined with spoofed internal email creates a dangerous new pretextWhich controls—IP-restricted connectors, automated containment, and out-of-band verification—actually close the gap Two questions your organization should be asking right now: If someone attempted a Direct Send from an unauthorized IP into your tenant tomorrow, would it be rejected?When was the last time you tested whether your employees follow out-of-band verification procedures under pressure?Resources: https://linktr.ee/ReliaQuestShadowTalk John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    From Data Dumps to Critical Findings: The New Era of Data Extortion

    Threat actors do not see old email archives, forgotten shared drives, and outdated CRM exports as clutter. They see them as searchable inventory. With AI-assisted analysis, attackers can rapidly identify sensitive communications, regulatory exposure, customer relationships, and credentials buried in stolen data. Join hosts John Dilgen and Brandon Tirado as they discuss: Why data theft has become a central component of modern extortion operationsHow AI and automation are helping attackers analyze hundreds of thousands of files at machine speedWhy “soft data,” including invoices and project documents, can fuel downstream fraud and social engineeringHow strong retention, credential-rotation, and OAuth-management practices reduce breach impactTwo questions your organization should be asking right now: How much data does your organization retain beyond its business or regulatory need?Could your team rotate hundreds of exposed credentials—not just one—before an attacker uses them?John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    Nation-State Actors: Iran’s PLC Attacks, Russia’s Zero-Click Email Exploit, and North Korea’s Fake Employees

    Three nation-states. Three distinct playbooks. Iranian actors are targeting internet-exposed industrial controllers and disabling critical safety systems.

Join hosts John Dilgen and Tehman Tariq as they break down: ✅ How Iranian actors manipulate PLC safety logic while keeping operators in the dark ✅ Why Russia’s zero-click exploit creates a major email-security and data-exfiltration risk ✅ How North Korean operatives use forged and stolen identities to infiltrate organizations as employees 🔑 Two questions your organization should be asking right now: Could your security team identify and secure internet-exposed PLCs, HMIs, and SCADA systems before an adversary does?Does your hiring process include controls to detect AI-generated documents, stolen identities, and malicious job applicants?👉 Tune in for expert insights and practical takeaways: ShadowTalk – ReliaQuest 👉 Find more podcast platforms, resources, and our listener feedback survey: ShadowTalk Official: X | Linktree
