Why Backups Aren't Enough & Identity Recovery is Key against Ransomware

Cloud Security Podcast

Show Notes

Think your cloud backups will save you from a ransomware attack? Think again. In this episode, Matt Castriotta (Field CTO at Rubrik) explains why the traditional "I have backups" mindset is dangerous. He distinguishes between Disaster Recovery (business continuity for operational errors) and Cyber Resilience (recovering from a malicious attack where data and identity are untrusted) . Matt speaks about the "dirty secrets" of cloud-native recovery, explaining why S3 versioning and replication are not valid cyber recovery strategies . The conversation shifts to the critical, often overlooked aspect of Identity Recovery. If your Active Directory or Entra ID is compromised, it's "ground zero” and you can't access anything. Matt argues that identity must be treated as the new perimeter and backed up just like any other critical data source . We also explore the impact of AI agents on data integrity, how do you "rewind" an AI agent that hallucinated and corrupted your data? Plus, practical advice on DORA compliance, multi-cloud resiliency, and the "people and process" side of surviving a breach.

Is the fear surrounding Anthropic’s Mythos model justified? In this episode, Ashish sits down with Johnny Hand, Global CISO at Trend AI and host of The AI Security Brief. Johnny breaks down why turning on a model like Mythos without a multi-stage orchestration layer is like handing someone the keys to a Ferrari when they don't know how to drive. He talks about the 66,000+ CVE "vulnpocalypse" panic and that only 1% of vulnerabilities are ever actively exploited in the wild. We also examine real-world autonomous threats like "Jade Puffer" (the first documented agentic ransomware path) and walk through 3-step maturity framework for enterprise AI adoption: Visibility, Observability, and Actionability via Agentic Governance Gateways

When companies rapidly migrate to the cloud without strict registrar policies, users often spin up unsanctioned subdomains pointed at third-party services like Vercel or Hugging Face. When those services are spun down but the DNS records remain, it creates "dangling" domains ripe for takeover, a vulnerability that can compromise entire hosted zones, auth tokens, and session cookies. In this episode, Ashish sits down with Ramesh Ramani, Staff Security Engineer at Block, to discuss how his team reduced their domain takeover bug bounty reports from over 80 in a single submission down to near zero. Ramesh breaks down the complex challenge of DNS attribution, explaining why automating DNS cleanup is impossible without first identifying resource owners and consolidating approved registrars. We explore the technical architecture behind Block's stateless, AWS-native automation system, which continuously enumerates their external attack surface and routes vulnerable CNAMEs, MX records, and Elastic IPs directly to the responsible application teams. Ramesh also shares his thoughts on the limitations of AI when evaluating least privilege and parsing logs, emphasizing why security engineers still need deterministic signals.

When an AI coding agent hallucinates a software package name, attackers can simply create malicious packages with that exact name, tricking the AI into downloading malware directly into your environment. In this episode, Ashish sits down with David Gibson, SVP of Strategic Programs at Varonis, to explain why the rapid adoption of AI copilots and autonomous agents is fundamentally a data security crisis. We spoke about how connecting AI to your corporate environment before locking down your data creates massive, unintentional insider threats, allowing employees to instantly discover sensitive information they shouldn't see. We explore the Varonis Atlas framework, which provides a unified control plane to inventory AI systems, implement runtime guardrails, and execute automated red teaming. David also breaks down emerging threats like "hallucination squatting," untrusted agent inputs, and why managing identity groups without understanding data access is like holding a keyring without knowing what doors the keys unlock.

Empowering non-technical users to build production-grade applications requires a proactive, secure-by-design architecture. In this episode, Ashish sits down with Marcus Hallberg and Samuel Kelemen, security engineers at the AI software creation platform Lovable, to discuss how they actively secure AI-generated code and protect creators from supply chain risks. Focusing on solutions rather than alarmism, Marcus and Samuel detail their response to an incident where malicious contractors mimicked AI agent commits. They outline their multi-layered defense strategy: securing a predefined tech stack, utilizing integrated security scanners, and tuning coding agents with strict guardrails to ensure secure output by default. The conversation also covers the evolution of the shared responsibility model in the AI era, the critical importance of foundational hygiene like Git commit signing, and the necessary transition from local "YOLO mode" to secure, sandboxed agent environments. Discover how platforms can leverage AI not just to write code, but to actively assist users in finding and resolving security issues through concepts like "CISO agents."

Hash values, IP addresses, and domains are virtually useless as primary detection mechanisms in the era of AI-driven polymorphic malware and short-lived phishing kits. If your detection strategy is still stuck at the bottom of the Pyramid of Pain, your incident response team is doused in noise while true threats slip through undetected. In this episode, Ashish sits down with Nicole Beckwith, Senior Director of Security Engineering & Operations at Cribl (former Secret Service investigator and Kroger security ops lead), to break down Cribl's open APEX framework. Nicole explains how APEX focuses on behavioral chaining, time-boxing, and clustering over raw telemetry to build high-fidelity detections without needing a thousand individual rules for every MITRE ATT&CK box. We also explore the shift from a "single pane of glass" to a deterministic "single lens" over federated data, why AI agents must be provisioned as true identities rather than unmonitored service accounts, and how to analyze hyper-fast threat archetypes like Anthropic's GTG 1002.
