Hiding in Plain Sight: Persistence in Backup Systems, AI Agents, Mobile Runtimes, and Hybrid Operations in Europe
From enterprise control planes to state-backed disruption, high-value trusted systems are becoming the attacker’s foothold
INTRODUCTION
This week is not about speed but strategic placement. The systems designed to enforce trust such as backup platforms, identity gateways, AI agent runtimes, and telecom infrastructure are becoming persistence layers. Attackers are targeting control planes that sit at the center of operational authority, where compromise grants leverage instead of noise. As authority concentrates in fewer platforms, the impact grows. The risk is no longer just faster exploitation but embedded access inside the systems defenders assume are secure.
If this issue helped clarify the signal, pass it along to someone shaping security strategy. Thanks for supporting The Monday Brief.
WEEKLY SIGNALS ANALYSIS
Prioritize immediate patching of Dell RecoverPoint, Ivanti EPMM, and BeyondTrust platforms before weekend exposure windows.
Monitor for web shells, SparkRAT, and GRIMBOLT persistence indicators in environments patched within the last 30 days.
Look for “knock-knock” traffic that doesn’t belong destined to high-value assets.
Begin red-teaming AI “agent” systems and runtime apps that execute with elevated credentials.
Track Russian hybrid interference across European infrastructure and make sure crisis communication plans integrate cyber response triggers.
THIS WEEK’S FOUR SIGNALS
Signal 1: Control Plane Compromise: Leveraging Recovery and Identity for Persistence
Why it matters: Dell RecoverPoint (CVE-2026-22769), Ivanti EPMM (CVE-2026-1281, 1340), and BeyondTrust (CVE-2026-1731) are all being exploited in the wild, allowing lateral movement across managed identity and recovery platforms. Attackers have been active for months, and in many environments these issues have escalated from pure patch management problems to ongoing compromise risks.
What is being misread: Many organizations treat these as isolated exposure events instead of connected campaigns. The overlap between GRIMBOLT and tooling seen in ransomware‑linked operations suggests sustained access campaigns, not one‑off hits.
Think Red (Douglas McKee): I’d go straight for the forgotten appliances and identity gateways that sit just outside MFA and EDR coverage. Why fight through endpoint controls when these systems are trusted by default? Web shells or RATs like SparkRAT let me automate persistence without triggering the ransomware alarms everyone’s watching for.
Act Blue (Ismael Valenzuela): Patch fast, but hunt smarter. Baseline normal access patterns to your recovery, IAM, and MDM control planes. Then look for the “knock-knock” traffic that doesn’t belong. IPs that have never connected in the last 30 days. ASNs you do not normally see. VPN exit nodes, Tor relays, residential proxy networks, or countries where you do not operate. Identify first-time source networks. Flag low-and-slow probes against authentication endpoints and administrative interfaces. Attackers often test access months before launching a campaign. What looks like harmless scanning today may be rehearsal traffic for tomorrow’s ransomware detonation.

Signal 2: Exploit Chains Target Developers Through “Agentic AI” Tooling
Why it matters: Malicious updates for Cline users deployed OpenClaw, a trojanized variant capable of credential interception within agent runtimes. These agents often hold access to source code, secrets vaults, and production APIs, bridging developer convenience into enterprise compromise.
What is being misread: Security leaders may frame this as another npm mishap. It’s not. This is an early example of what we can call “AI runtime poisoning,” where attackers manipulate semi-autonomous software agents integrated into build and deployment pipelines. The impact is fundamentally different.
Think Red (Douglas McKee): This isn’t new. We’ve been stealing credentials out of memory for decades. Mimikatz worked because systems cached authority where we could reach it. Agent runtimes are doing the same thing, just with OAuth tokens and cloud API keys instead of NTLM hashes. If I can observe that exchange once, I don’t need persistence on the laptop. I have persistence in the workflow.
Act Blue (Ismael Valenzuela): Treat AI agents as privileged identities, not just developer conveniences. Isolate all agent systems under strict RBAC, separate credentials per function, and strip network egress unless explicitly required. Establish a digital “quarantine” for new dependencies and version updates before promoting them to production. This is supply chain security applied to runtime, not just build time.

Signal 3: Malware Gains On-Device AI Decision-Making
Why it matters: PromptSpy demonstrates adversarial use of LLMs for persistence and environment-aware adaptation on Android devices, enabling data theft and evasion through local AI decision-making. This represents a leap from neural lure generation to on-device autonomy.
What is being misread: Most believe AI in malware remains experimental or inefficient. The lightweight inferences now possible on-device make “smart persistence” practical for criminals at scale. We’ve crossed a threshold.
Think Red (Douglas McKee): Using Gemini or similar models locally, I can react dynamically to EDR presence by altering my persistence method or delaying activity until the device is idle. This increases dwell time without heavy C2 traffic. The malware adapts so I don’t have to.
Act Blue (Ismael Valenzuela): Security teams must move beyond static indicators on mobile platforms. Baseline normal app behavior and monitor for dynamic permission changes, abnormal traffic patterns to LLM services, unexpected model endpoints, or encrypted payload sizes inconsistent with normal app behavior. Sudden spikes in data volume to AI APIs should raise questions. Baseline which applications are legitimately invoking on-device or cloud-hosted models. Flag anything outside that allowlist. And if you suspect exposure, move fast. Pull device telemetry, review network flows to known LLM providers, rotate tokens, and assume that any locally cached secrets may have been observed.

Signal 4: Hybrid Operations in Europe Blur the Line Between Cyber Espionage and Disruption
Why it matters: Recent Dutch intelligence warnings describe increased Russian hybrid actions affecting EU critical sectors, including transport and energy. This suggests a shift from espionage-only to coercive disruption designed to destabilize public trust.
What is being misread: Media narratives still separate “cyber warfare” from “influence operations.” Moscow’s ongoing campaigns combine both. Infrastructure stress testing through DDoS and short outages are precursors, not standalone events.
Think Red (Douglas McKee): State‑linked operators are assessed in multiple reports to use ransomware‑style operations and proxies to obscure disruptive or sabotaging objectives in critical sectors. Telecoms and logistics sectors that serve dual-use civilian and military needs are natural soft targets to erode morale. The goal isn’t always encryption. Sometimes it’s just chaos.
Act Blue (Ismael Valenzuela): CISOs in EU critical infrastructure sectors should synchronize cyber incident playbooks with crisis PR and continuity teams. Invest in real defensible security architectures built on zero trust principles, decoy infrastructure (aka. taking the adversary by surprise), and invest in cross-border telemetry coverage and behavioral detection so stress-testing activity is recognized as coordinated pressure, not random noise. The organizational silos here create real defensive blind spots.

MEME OF THE WEEK
Why kick the door down when you can just print your own badge?
2026 attackers are not smashing glass. They’re owning the badge printer, the backup server, and the “trusted” control panel nobody is watching.
ROLE-BASED TAKEAWAYS
Executive / CISO / Board Level
Verified exploitation of high-severity zero-days across identity and management platforms demands accelerated patch SLA targets: 48 hours maximum for external systems.
AI-assisted malware and agentic tooling compromises require new governance categories in risk registers.
EU hybrid threat escalation means mandatory inclusion of geopolitical risk in 2026 business continuity assessments.
Enterprise Architect
Design Principle Impact: Isolation and least privilege must extend to application agents and automation scripts that act on behalf of users or services.
New Constraint/Dependency: Secure dependency provenance and runtime integrity verification become gating criteria for CI/CD workflows.
Security Operations
Implementation Watch Item: Look for GRIMBOLT, VShell, or SparkRAT processes in backup or IAM systems.
Common Failure Mode: Treat control plane telemetry as early warning radar, not just log exhaust.
Monitoring Patterns: Web shell creation in unusual directories on management servers, anomalous service restarts after hours.
Signal vs Noise Guidance: Ignore single failed login alerts unless correlated with system process anomalies. Prioritize new binary drops or outbound TLS to high-entropy domains.
Take the adversary by surprise: Deploy deception web shells or fake API keys within dev environments to trigger alerts on illicit access attempts. Convert attacker dwell time into early warning.
See you next Monday!
