    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    Threat actors do not see old email archives, forgotten shared drives, and outdated CRM exports as clutter.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. A Russian threat group built a zero-click email exploit that steals 90 days of inbox data the moment a user views a message. And North Korean operatives are applying for software-development jobs at Western companies—and getting hired. 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

    When AI Escapes the Lab: The Hugging Face Breach, PyPI Malware, and What It Means for Defenders

    Fully autonomous attacks are here. AI agents escape a test environment, exploit zero-days, coordinate through shared infrastructure, and breach a production company—generating more than 17,000 security events along the way. Elsewhere, another model autonomously publishes malware to PyPI, while AI agents target real open-source developers with tailored social engineering.  Join hosts John Dilgen and Tehman Tariq as they break down: ✅ How AI agents escaped containment and compromised Hugging Face infrastructure ✅ Why Claude’s autonomous PyPI attack signals growing software-supply-chain risk ✅ How coordinated AI agents deceived real developers 🔑 Two questions your organization should be asking right now: Could your SOC investigate and contain 17,000 coordinated events at machine speed?What deception controls do you have in place to slow an AI agent attack? 👉 Tune in for expert insights and practical takeaways: ShadowTalk – ReliaQuest 👉 Find more podcast platforms, resources, and our listener feedback survey: ShadowTalk Official: X | Linktree

    The Gentlemen, Deadlock, and Clop: The Groups Driving Ransomware & Extortion in 2026

    An affiliate receives a ready-made intrusion kit — pre-compromised targets, an EDR killer, and a full deployment workflow included. No building from scratch. No long ramp-up. Just deploy, observe, and iterate. That's the future of ransomware; it's how the new number-one group operated in Q2 2026. And it's just one of three stories reshaping the extortion landscape right now. Join hosts Brandon Tirado and John Dilgen as they break down: How The Gentlemen's pre-packaged affiliate kit drove 580% leak-site growthWhy Deadlock's Polygon blockchain C2 defeats network defensesClop's latest campaign targeting an industrial enterprise application Two questions your organization should be asking right now: Do you know exactly where your EDR coverage ends?If a critical vendor were compromised tonight, would you hear it from them first — or from your own monitoring?John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.

    Compromised Hotel Gateways, Fake Microsoft Domains, and the APT28-Adjacent Campaign That Bypasses MFA Without a Phishing Click

    An employee connects to hotel Wi-Fi, receives a familiar Microsoft 365 sign-in prompt, and authenticates. No phishing email. No malicious link. No suspicious attachment. Yet an attacker walks away with a valid, MFA-satisfied session token.  Join hosts Alexandra Moore and John Dilgen as they break down: How compromised hotel and conference-center Wi-Fi gateways silently redirect Microsoft authentication trafficWhy hardcoded DNS, opportunistic encrypted DNS, and MFA may not stop the attackHow device-code phishing and WPAD abuse expand the campaign’s reachPractical defenses—including always-on, full-tunnel VPN, strict-mode encrypted DNS, and Conditional Access controls Two questions your organization should be asking right now: Does your always-on VPN tunnel all DNS and authentication traffic, or do split-tunneling exceptions leave traveling employees exposed?Who is permitted to authenticate through the device-code flow, and does each exception have a legitimate business justification?John Dilgen: Cyber Threat Intelligence Analyst at ReliaQuest, where he specializes in researching cyber threats impacting ReliaQuest customers.
