Cyberside Chats: Cybersecurity Insights from the Experts

Claude Opus 4.6 is generating serious buzz for one reason: it can rapidly spot zero-day vulnerabilities out of the box, suggesting that long-trusted software may no longer be as “safe by default” as security teams assume.

At the same time, Microsoft’s February patch cycle included an unusually high number of zero-days already under active exploitation — real-world evidence that the race is already accelerating, and the window between discovery and impact is shrinking.

In this Cyberside Chats Live, we’ll connect the dots on what this means for defenders in 2026: a shrinking window between discovery and exploitation, shifting assumptions about “well-tested” software, and practical ways to rethink patch prioritization, detection, and exposure management.

 

Key Takeaways:

1. Plan for exploitation before disclosure - The era of negative-day vulnerabilities is here, flaws that may be discovered and weaponized before the broader security community even knows they exist. Assume exploitation could precede public advisories. Build response models around mitigation speed, not just patch timelines.

2. Prioritize exposure, not just severity - In a compressed exploit cycle, CVSS alone won’t protect you. Focus first on internet-facing systems, identity infrastructure, and high-privilege assets. If you cannot quickly identify what is externally reachable, that visibility gap becomes strategic risk.

3. Assume compromise on exposed assets and monitor accordingly - If attackers can exploit vulnerabilities before the world knows they exist, you may be compromised without a CVE to point to. Increase monitoring on internet-facing systems and critical apps for signs of intrusion: unexpected processes, new admin accounts, unusual authentication patterns, suspicious outbound connections, and persistence mechanisms.

4. Treat compensating controls as first-line defense - When patches aren’t available or cannot be deployed immediately rapid mitigations matter. Restrict access, disable vulnerable features, deploy firewall and WAF protections, and tighten segmentation. Mitigation agility should be operational, tested, and pre-authorized.

5. Prepare for containment patches may not exist - If exploitation is confirmed and no fix is available, leadership decisions must happen quickly. Define in advance who can isolate systems, disable services, revoke credentials, or temporarily disrupt operations. Shorten containment decision cycles before you need them.

6. Rehearse a “negative-day” tabletop - Run a scenario where exploitation is active, no patch exists, and public disclosure hasn’t occurred. Measure how fast you can reduce exposure, hunt internally, and communicate with executives. This exercise will expose friction points that policies alone will not.

7. Integrate AI into your vendor risk model - If AI is accelerating vulnerability discovery and code generation, your third parties are likely using it too. Update vendor due diligence to assess how AI-generated code is reviewed, secured, and tested. Ask about model governance, secure development controls, and vulnerability response timelines. If you lack visibility into how vendors manage AI risk, that gap becomes part of your attack surface.

After the FBI announced it recovered previously inaccessible video from Nancy Guthrie’s disconnected Google Nest doorbell, one thing became clear: in releasing the footage, authorities revealed an important truth — deleted surveillance footage may not really be deleted. That means law enforcement (or threat actors) could potentially access it.

The case remains ongoing and deeply serious. For enterprise security leaders, the lesson is bigger than a consumer camera: modern systems often retain residual data across devices, local buffers, and vendor backends, even when teams believe it has been removed. In this episode of Cyberside Chats, we examine what that means for corporate environments, including IoT and physical security systems, data retention and legal exposure, vendor access models, and incident response realities when “deleted” data can still be recovered.

This case underscores a complex reality: data can remain accessible long after we believe it’s gone: sometimes a source of risk, and sometimes invaluable.

 

Key Takeaways:

1. Treat vendors as part of your data perimeter - Review contracts and platform settings to understand who can access footage or logs, what “support access” entails, what data is retained in backend systems, and how data is handled during incident response or legal requests.

2. Control encryption keys and access paths - Know who holds encryption keys, how administrative access is granted and monitored, and whether “end-to-end encryption” claims align with your threat model and regulatory requirements.

3. Include IoT and security devices in your data inventory - Cameras, badge systems, and smart building technology are data systems. Document on-device storage, cloud sync behavior, local buffers, and backend retention — not just cloud repositories.

4. Align retention decisions with legal and regulatory risk - Longer retention may aid investigations but increases eDiscovery scope, breach exposure, and privacy obligations. Retention should be a deliberate business risk decision made with Legal and Compliance.

5. Test whether deletion actually works - Validate purge workflows across vendor platforms and internal systems, including backups and disaster recovery, because “logical deletion” often isn’t “forensic deletion.” Build policies around how long data persists in replicas, backups, buffers, and vendor systems — and plan accordingly in both incident response and governance strategy.

Ransomware gangs aren’t operating alone anymore and the lines between them are increasingly blurry.

In this episode of Cyberside Chats, we look at how modern ransomware groups collaborate, specialize, and team up to scale attacks faster. Using ShinyHunters’ newly launched data leak website as an example, we discuss how different crews handle access, social engineering, and data exposure, and why overlapping roles make attribution, defense, and response harder.

We also explore what this shift means for security leaders, from training and identity protection to preparing for data extortion that doesn’t involve encryption.

 

Key Takeaways

1. Harden identity and SaaS workflows, not just endpoints - Review help desk procedures, SSO flows, OAuth permissions, and admin access. Many recent incidents succeed without malware or exploits.

2. Train staff for voice phishing and IT impersonation - Add vishing scenarios to security awareness programs, especially for help desk and IT-adjacent roles.

3. Limit blast radius across cloud and SaaS platforms - Enforce least privilege, audit third-party integrations, and regularly review OAuth scopes and token lifetimes.

4. Plan for data extortion without ransomware - Update incident response plans and tabletop exercises to assume data theft and public exposure, even when no systems are encrypted.

5. Practice executive decision-making under data exposure pressure - Tabletop exercises should include legal, communications, and leadership discussions about public leaks, reputational risk, and extortion demands.

AI is no longer a standalone tool—it is embedded directly into productivity platforms, collaboration systems, analytics workflows, and customer-facing applications. In this special CyberSide Chats episode, Sherri Davidoff and Matt Durrin break down why lack of visibility and control over AI has emerged as the first and most pressing top threat of 2026.

Using real-world examples like the EchoLeak zero-click vulnerability in Microsoft 365 Copilot, the discussion highlights how AI can inherit broad, legitimate access to enterprise data while operating outside traditional security controls. These risks often generate no alerts, no indicators of compromise, and no obvious “incident” until sensitive data has already been exposed or misused.

Listeners will walk away with a practical framework for understanding where AI risk hides inside modern environments—and concrete steps security and IT teams can take to centralize AI usage, regain visibility, govern access, and apply long-standing security principles to this rapidly evolving attack surface.

 

Key Takeaways

1. Centralize AI usage across the organization. Require a clear, centralized process for approving AI tools and enabling new AI features, including those embedded in existing SaaS platforms.

2. Gain visibility into AI access and data flows. Inventory which AI tools, agents, and features are in use, which users interact with them, and what data sources they can access or influence.

3. Restrict and govern AI usage based on data sensitivity. Align AI permissions with data classification, restrict use for regulated or highly sensitive data sets, and integrate AI considerations into vendor risk management.

4. Apply the principle of least privilege to AI systems. Treat AI like any other privileged entity by limiting access to only what is necessary and reducing blast radius if credentials or models are misused.

5. Evaluate technical controls designed for AI security. Consider emerging solutions such as AI gateways that provide enforcement, logging, and observability for prompts, responses, and model access.

The recent Verizon outage underscores a growing risk in today’s technology landscape: when critical services are concentrated among a small number of providers, failures don’t stay isolated.

In this live discussion, we’ll connect the Verizon outage to past telecom and cloud disruptions to examine how infrastructure dependency creates cascading business impact. We’ll also explore how large-scale outages intersect with security threats targeting telecommunications, where availability, confidentiality, and integrity failures increasingly overlap.

The session will close with actionable takeaways for strengthening resilience and risk planning across cybersecurity and IT programs.

 

Key Takeaways

1. Diversify your technology infrastructure. Relying on a single carrier, cloud provider, or bundled service creates a single point of failure. Purposeful diversification across providers can reduce the impact of large-scale outages and improve overall resilience.

2. Treat outages as security incidents, not just reliability problems. Large-scale telecom and cloud outages directly disrupt authentication, monitoring, and incident response, and should trigger security workflows—not just IT troubleshooting.

3. Identify and document your dependencies on carriers and cloud providers. Many security controls rely on SMS, voice, cloud identity, or single regions; understanding these dependencies ahead of time prevents dangerous blind spots during outages.

4. Plan and test incident response without phones, SMS, or primary cloud access. Assume your normal communication and authentication methods will fail and ensure your teams know how to coordinate securely when core services are unavailable.

5. Expect outages to increase fraud and social engineering activity. Attackers exploit confusion and urgency during service disruptions, so security teams should prepare staff for impersonation and “service restoration” scams during major outages.

6. Use widespread outages as learning opportunities. Review what happened, assess how your organization was—or could have been—impacted, identify potential areas for improvement, and update incident response, communications, and resilience plans accordingly.

The FTC has issued an order against General Motors for collecting and selling drivers’ precise location and behavior data, gathered every few seconds and marketed as a safety feature. That data was sold into insurance ecosystems and used to influence pricing and coverage decisions — a clear reminder that how organizations collect, retain, and share data now carries direct security, regulatory, and financial risk. 

In this episode of Cyberside Chats, we explain why the GM case matters to CISOs, cybersecurity leaders, and IT teams everywhere. Data proliferation doesn’t just create privacy exposure; it creates systemic risk that fuels identity abuse, authentication bypass, fake job applications, and deepfake campaigns across organizations. The message is simple: data is hazardous material, and minimizing it is now a core part of cybersecurity strategy. 

Key Takeaways:

1. Prioritize data inventory and mapping in 2026 

You cannot assess risk, select controls, or meet regulatory obligations without knowing what data you have, where it lives, how it flows, and why it is retained. 

2. Reduce data to reduce risk 

Data minimization is a security control that lowers breach impact, compliance burden, and long-term cost. 

3. Expect that regulators care about data use, not just breaches 

Enforcement increasingly targets over-collection, secondary use, sharing, and retention even when no breach occurs. 

4. Create and actively use a data classification policy 

Classification drives retention, access controls, monitoring, and protection aligned to data value and regulatory exposure. 

5. Design identity and recovery assuming personal data is already compromised 

Build authentication and recovery flows that do not rely on the secrecy of SSNs, dates of birth, addresses, or other static personal data. 

6. Train teams on data handling, not just security tools 

Ensure engineers, IT staff, and business teams understand what data can be collected, how long it can be retained, where it may be stored, and how it can be shared.

When Venezuela experienced widespread power and internet outages, the impact went far beyond inconvenience—it created a perfect environment for cyber exploitation. 

In this episode of Cyberside Chats, we use Venezuela’s disruption as a case study to show how cyber risk escalates when power, connectivity, and trusted services break down. We examine why phishing, fraud, and impersonation reliably surge after crises, how narratives around cyber-enabled disruption can trigger copycat or opportunistic attacks, and why even well-run organizations resort to risky security shortcuts when normal systems fail. 

We also explore how attackers weaponize emergency messaging, impersonate critical infrastructure and connectivity providers, and exploit verification failures when standard workflows are disrupted. The takeaway is simple: when infrastructure collapses, trust erodes—and cybercrime scales quickly to fill the gap. 

The December release of the Epstein files wasn’t just controversial—it exposed a set of security problems organizations face every day. Documents that appeared heavily redacted weren’t always properly sanitized. Some files were pulled and reissued, drawing even more attention. And as interest surged, attackers quickly stepped in, distributing malware and phishing sites disguised as “Epstein archives.” 

In this episode of Cyberside Chats, we use the Epstein files as a real-world case study to explore two sides of the same problem: how organizations can be confident they’re not releasing more data than intended, and how they can trust—or verify—the information they consume under pressure. We dig into redaction failures, how AI tools change the risk model, how attackers weaponize breaking news, and practical ways teams can authenticate data before reacting.
