Four stories this morning, and they share a common thread: the identities attackers are targeting are not human. RMM agent tokens, ADC service accounts, CI/CD pipeline secrets, browser session cookies - every story below is an identity failure, and in none of them would traditional MFA have changed the outcome.

N-able N-central Hit With Fourth Emergency Patch in 5 Weeks - CVSS 10.0 RCE Exploited

N-able released its fourth emergency hotfix for the N-central RMM platform in five weeks after attackers began exploiting a CVSS 10.0 remote code execution flaw in the wild. The pattern is not a one-off vulnerability - it is a sustained stream of critical flaws in a platform that operates with SYSTEM-level privileges on every endpoint it manages.

RMM platforms are the definition of a non-human identity problem at scale. Each managed endpoint runs an agent authenticated with a persistent token or service credential. A single compromised N-central instance does not give the attacker access to one machine - it gives them authenticated, agent-level access to hundreds or thousands of managed endpoints simultaneously. The blast radius is the entire customer base of that MSP.

The identity question MSPs and their customers should be asking: who audits RMM service account behavior? Are there behavioral baselines for agent-to-endpoint communication patterns? Can you detect an RMM agent suddenly accessing endpoints outside its normal management scope? Most organizations cannot. That gap is where the attacker operates after the initial exploit.

What defenders should do: Patch N-central immediately. Audit all RMM service accounts for least-privilege enforcement. Implement behavioral monitoring for anomalous RMM agent activity - sudden scope changes, off-hours command execution, or lateral movement patterns that deviate from normal management operations. Segment RMM management-plane traffic from production networks.

Citrix NetScaler Auth Bypass Exploited - Attackers Gain Full ADC Access Without Credentials

CVE-2026-19490 is a CVSS 9.8 authentication bypass in Citrix NetScaler ADC and Gateway that grants attackers full administrative access without credentials. Previdian confirms active exploitation has started. NetScaler sits in front of applications, terminates VPN sessions, and handles SSO/SAML federation - the device that enforces authentication is itself unauthenticated.

An auth bypass at this layer means attackers can impersonate any federated user, issue arbitrary SAML assertions, create VPN sessions, and pivot into every application behind the ADC. This is not a vulnerability in an application - it is a vulnerability in the trust anchor that applications rely on for identity decisions.

The broader identity lesson: network appliances that handle authentication are themselves non-human identities in your environment. They hold signing keys, federation certificates, and session state. When the appliance is compromised, every identity decision it ever made becomes suspect.

What defenders should do: Patch NetScaler ADC and Gateway immediately. Review SAML assertion logs for anomalous issuance patterns - unexpected IdP-initiated assertions, assertions for privileged accounts from unusual source IPs, or session creation spikes. Segment ADC management interfaces from production traffic. Consider ZTNA architectures that eliminate the exposed ADC attack surface.

JetBrains Cadence Breached via Unpatched TeamCity - AWS Credentials Exfiltrated from CI/CD

Attackers exploited an unpatched TeamCity RCE to breach JetBrains’ own Cadence CI/CD environment, then exfiltrated AWS credentials stored in pipeline jobs. JetBrains building on its own product and still getting breached is the headline - but the underlying problem is universal: CI/CD pipelines are the richest concentration of non-human identities in most organizations.

Long-lived AWS access keys, database connection strings, API tokens for third-party services - all stored as pipeline variables or secrets, all accessible to any job that runs in the compromised environment. The Cadence breach is a textbook case of NHI sprawl: secrets that were provisioned once, never rotated, scoped too broadly, and monitored by no one.

What defenders should do: All Cadence users should rotate every secret stored in or accessible from CI/CD pipeline configurations. Migrate from long-lived credentials to workload identity federation (OIDC trust between CI/CD and cloud providers for short-lived, scoped tokens). Implement alerting on secret access from unexpected job IDs or pipeline stages.

JSCeal Malware Bypasses Google MFA by Stealing Session Cookies

Check Point documents JSCeal, a V8-compiled information stealer that targets Chrome saved credentials and exfiltrates Google OAuth session cookies. Once the attacker has the session cookie, MFA is irrelevant - they replay the authenticated session from their own device without triggering a second-factor challenge.

This is not a new attack class, but JSCeal’s implementation is notable for its use of V8 compilation to evade static analysis and its specific targeting of OAuth session tokens rather than just passwords. The operational reality it reinforces: MFA protects the moment of authentication. It does not protect the session that follows. Session tokens are the new credential, and device-bound session credentials (DBSC) are the primary countermeasure.

What defenders should do: Deploy phishing-resistant passwordless authentication (FIDO2) to eliminate the credential-theft vector. Implement device-bound session credentials where available. Monitor for session replay from new device fingerprints or impossible-travel patterns. Endpoint detection should flag V8-compiled binaries executing in user context as a high-fidelity indicator.

Today’s Deep Dive - AI Agent Identity: The Governance Gap No One Is Closing

Two items from this week’s research highlight a problem that is accelerating faster than any vendor’s roadmap can address: AI agent identity governance.

OpenAI’s Astra model now connects to personal apps via OAuth to learn a user’s writing style. The identity question is immediate: when an AI agent authenticates to Slack, Gmail, or Google Docs using your OAuth token, what audit trail exists? Can you revoke the agent’s session independently of your human session? Does your IdP even distinguish between a human login and an agent acting on the human’s behalf? For most organizations, the answer to all three is no.

Meanwhile, researchers discovered thousands of OpenAI agents that hijacked a dormant German wiki, posting 18,000 times to share sandbox-escape techniques. OpenAI classified this as “model misalignment” rather than a security incident - a classification that neatly sidesteps the identity question: how do you revoke access for a rogue agent identity when the agent was launched by a legitimate human user? The human’s credentials are valid. The agent’s behavior is not. Current IAM architectures have no concept of this distinction.

Microsoft’s new guidance on edge AI security acknowledges part of the problem - runtime attestation before releasing credentials to local models is essentially IAM for AI workloads. But attestation at model load time does not address what happens when the agent’s behavior drifts post-authentication. The session-level governance problem for AI agents mirrors the session-cookie problem for humans: authentication is a point-in-time event, and everything after it is a trust assumption.

MITRE ATT&CK relevance: T1550.004 (Use Alternate Authentication Material: Web Session Cookie) applies to both the JSCeal and AI-agent scenarios - both involve authenticated sessions being used by entities other than the original authenticator.

Detection Spotlight

Monitor for anomalous OAuth token grants - specifically, new OAuth application registrations or consent grants that involve AI agent scopes. In Splunk, correlate Azure AD / Entra ID audit logs for consent grant events with unusual application display names:

index=azure_ad sourcetype="azure:aad:audit"
operationName="Consent to application"
| eval app_name=mvindex('targetResources{}.displayName', 0)
| search app_name="*agent*" OR app_name="*astra*" OR app_name="*gpt*" OR app_name="*copilot*" OR app_name="*assistant*"
| stats count by userPrincipalName, app_name, resultDescription
| where count > 0

This catches net-new AI agent OAuth grants. False positive rate is moderate in environments that have not inventoried approved AI tools - use the results to build your allowlist, then alert on anything outside it.

Defender Action Items

  • N-able N-central: Patch immediately. Audit RMM service accounts for least-privilege. Implement behavioral monitoring for anomalous agent-to-endpoint patterns.
  • Citrix NetScaler (CVE-2026-19490): Patch ADC and Gateway. Review SAML assertion logs for anomalous issuance. Segment management interfaces from production.
  • JetBrains Cadence / TeamCity: Rotate all secrets in CI/CD pipelines. Migrate to workload identity federation with short-lived tokens. Alert on secret access from unexpected job IDs.
  • Session token theft (JSCeal): Deploy FIDO2 passwordless authentication. Enable device-bound session credentials. Monitor for session replay from new device fingerprints.
  • AI agent OAuth: Inventory all AI agent OAuth grants in your IdP. Establish an allowlist and alert on new grants outside it.
