Machine Learning SinFP Model Updates for OS Fingerprinting
Summary Updates have been released for the Tenable MLSinFP model, which predicts a host's OS based on SinFP fingerprints, by rebuilding it on a newer tech stack, incorporating new features, and using a larger dataset, resulting in improved accuracy of 67%. Change Before this update, plugin 132935 “OS Identification: SinFP with Machine Learning” was targeting operating systems commonly seen up to January 2021; consequently any newer OSs were not available as predictions. Additionally, the plugin solely relied on TCP header information for model features. After this update, the plugin targets operating systems commonly seen up to May 2025. Additionally the training dataset is larger (was 700K records, now 1.8M) and more varied (was 6K distinct SinFP fingerprints, now 100K), the predicted OSs names are cleaner and more consistent, and model features other than TCP header information are relied on. Ultimately these changes resulted in the plugin's balanced accuracy increasing to 67% (was 54%). Impact Remote detection of operating systems based on the MLSinFP method will have a slightly higher confidence score. Assets whose operating system was determined based on this method might have a different detected operating system. Plugins 132935 - OS Identification: SinFP with Machine Learning Target Release Date October 27, 2025

Tenable Identity Exposure Tenable Identity Exposure uncovers Storm-0501's cloud identity threats: Financially motivated threat actor Storm-0501 is advancing cloud-based ransomware and hybrid identity compromises to move seamlessly between on-premises Active Directory (AD) and Microsoft Entra ID. Tactics include initial identity exploitation that compromises AD and abuses non-human synced Global Admin accounts in Entra ID, along with malicious persistence, where they establish backdoors by adding rogue federated domains with tools like AADInternals to gain persistent access and impersonation capabilities. Attacker tactic How Tenable Identity Exposure prevents it Initial compromise Flags high-privilege, improperly synced Entra ID accounts from on-prem AD, a configuration Microsoft advises against. MFA bypass Identifies critical, privileged accounts missing MFA, one of the most exploited gaps in hybrid identity attacks. Malicious persistence Detects backdoor federated domains and anomalous signing certificates using multiple indicators of exposure (IOEs), including: Known Federated Domain Backdoor, Federation Signing Certificates Mismatch, Unusual Federation Certificate Validity, Federated Domains List for verification against legitimate IDPs. Tenable Identity Exposure continuous monitoring of IoEs uncovers and aids remediation of critical identity risks before groups like Storm-0501 can exploit them.

Summary Tenable has updated the Apache Log4j detection plugins. The Windows plugin will now honor the Include/Exclude Filepath configuration option. The Linux/UNIX plugin will now use the version of ‘unzip’ supplied with the Nessus Agent, when enabled in the Agent’s configuration, and correctly inspect the MANIFEST.MF and pom.properties files. Change Before this update, plugin 156000, Apache Log4j Installed (Linux / Unix), would fail to detect Log4j in specific scan scenarios. The plugin uses several inspection methods to determine if a JAR file is a copy of Log4j. During Nessus Agent scans, as well as scans with ‘localhost’ as a target, the plugin was not properly executing the unzip command to inspect META-INF/MANIFEST.MF and pom.properties files in the JAR archive. If this method was the only option that would result in a successful detection, the copy of Log4j would not be detected properly. In addition, the plugin had failed to launch the unzip binary supplied with the Agent when inspecting files in JAR archives. Note: The Nessus Agent can be configured to use find and unzip binaries that it provides, instead of those supplied by the asset’s operating system. See https://docs.tenable.com/vulnerability-management/Content/Scans/AdvancedSettings.htm#Agent_Performance_Options for more information. Also before this update, plugin 156001, Apache Log4j JAR Detection (Windows), would fail to honor the directories included or excluded for full-disk searches configured in the Windows Include Filepath and Windows Exclude Filepath directives in the Advanced Settings of a scan config. Note: Configuration of these options is described in https://docs.tenable.com/vulnerability-management/Content/Scans/AdvancedSettings.htm#Windows_filesearchOptions. After this update, plugin 156000 will use the Agent-supplied copy of unzip when configured to do so. If this option is not enabled in the scan config, the plugin will use the existing method to find and execute an archive utility supplied by the asset’s operating system. In either case, the plugin will properly inspect Log4j’s MANIFEST.MF and pom.properties files as a version source. Plugin 156001 already properly inspects these files. Also after this update, plugin 156001’s Powershell code will now honor directories included or excluded by the Filepath directives. Plugin 156000 already supported this feature. Impact When scanning Linux / UNIX assets via 'localhost' (i.e. scanning the scanner itself) or with the Nessus Agent, additional Log4j instances from MANIFEST.MF or pom.properties sources may be reported. For Linux Nessus Agents with "Use Tenable supplied binaries for find and unzip" enabled and "Agent CPU Resource Control - Scan Performance Mode" set to Low, plugin 156000 will now properly limit CPU usage during scans. As noted in the product documentation, “Note: Setting your process_priority preference value to low could cause longer running scans. You may need to increase your scan-window timeframe to account for this value.” Customers should be aware of this configuration setting and potential changes to the results provided in the Log4J detection results. When scanning Windows targets, Log4j JAR files stored in paths specified in the Windows Exclude Filepath configuration will no longer be detected. Log4j JAR files stored in paths or drives specified in the Windows Include Filepath configuration that had not been previously scanned will now be detected, assuming they can be assessed before the plugin’s configured timeout has been reached. Plugins 156000 - Apache Log4j Installed (Linux / Unix) 156001 - Apache Log4j JAR Detection (Windows) Target Release Date September 1, 2025Excluding the SUSE Linux Snapshots directory from Language Library enumeration
Summary The “language library” enumeration plugins will now exclude SUSE Linux’s snapshots directory when searching the filesystem. Change Before the update, when enumerating “language libraries” - such as Python packages, Node.js modules, etc. - on SUSE Linux hosts that use btrfs as their filesystem, reduced scan performance was observed. This is because btrfs creates and maintains snapshots in the /.snapshots directory, which can contain multiple redundant copies of files. This caused unnecessary processing on thorough scans. After the update, this snapshots directory has been excluded from searches executed by the find command for language library enumeration plugins on SUSE Linux. Impact This change is expected to improve the performance of scans on SUSE Linux assets. If language libraries were present in snapshots directory, they will no longer show up in Tenable scan results, along with any associated vulnerabilities. If customers would like to scan the snapshots directory, the "Include Filepath" option in the Advanced Scan Settings configuration can be used to force the scanning of these paths.

Tenable now natively supports Azure Resource Manager (ARM) and Bicep, expanding on existing coverage for AWS CloudFormation, Kubernetes YAML, and Terraform across all major cloud environments. Azure users can now scan for misconfigurations directly in their infrastructure as code. Notably, Tenable Cloud Security uniquely supports Bicep, which is rapidly gaining adoption due to its simplicity. Tenable tags resources in Bicep files, auto-generates underlying ARM templates, and highlights misconfigurations directly in the Bicep code, so you can work in the Bicep layer without parsing ARM output. We’ve also introduced ingestion of Tenable IaC findings via API using the “Findings” query in the GraphQL API. This enables programmatic management of finding status. The code API has full UI parity and is consistent with all Tenable API endpoints. Workload protection now supports Oracle Cloud Infrastructure + streamlined reporting. Expanding our coverage of Oracle Cloud Infrastructure (OCI), Tenable Cloud Security now offers workload protection for OCI environments. You can scan virtual machines, including those using OCI-native and customer-managed key (CMK) encrypted volumes, alongside container images and account-level resources. Additionally, across all supported cloud environments, we have streamlined reporting: you can now generate reports directly from the Vulnerabilities page, simplifying your workflow. Enhanced IAM security across permissions and access. Tenable Cloud Security’s Microsoft Entra ID integration, recently enhanced with third-party support and MFA monitoring, can now monitor and filter all app API and delegated permissions. IAM admins get a clearer, tenant-wide view of app-level permissions, making it easier to remove unnecessary access. Are you still using the now-retired Microsoft Entra Permissions Management? Tenable is a strong replacement, with advanced CIEM, JIT access, and CNAPP capabilities spanning Entra ID, Azure and more. We’ve also improved IAM visibility for AWS and GCP with exportable Permissions Query results and enhanced tracking of custom policy changes. In GCP, access-level evaluation is now deeper with added behavior analysis and resource details. Introducing custom dashboards that you can easily build in minutes. You’ve got the power! You can now customize how dashboards look and how you present security data to help users focus on what matters most. Personalize dashboards by adjusting metrics, findings and visualizations. Choose whether to make them public or private. Save time by duplicating built-in or custom dashboards. Plus, all dashboards are now centrally located in the menu for easier access. “Projects” capability now supports integrations and automations by scope. Tenable is making it easier to manage accounts and access control across multiple accounts and providers. The Projects capability, which logically groups resources in your cloud environment, now lets you configure integrations and automations at the project level. This enables more granular control and flexibility to let specific accounts or resources follow tailored workflows aligned with your organizational structure and security policies. Tenable Identity Exposure New Entra ID IoEs to strengthen identity hygiene. Tenable has added new indicators of exposure (IoEs) to help you identify and remediate hidden risks in Entra ID environments: Managed devices not required for MFA registration: Flags tenants that allow multi-factor authentication (MFA) registration from devices your organization doesn’t manage. Without requiring managed devices, attackers with stolen credentials could set up their own MFA methods without your knowledge. Admin consent workflow not configured: Detects tenants missing an active admin consent workflow. This absence can cause errors for non-admin users trying to access applications that need consent, leading to user friction or unmonitored workarounds. Password expiration enforced: Identifies domains where password expiration policies, intended to enhance security, might actually weaken it. When you force users to change passwords frequently, they often resort to simpler or repeated passwords, which makes them more vulnerable to breaches. For more information, review the release notes. Tenable Enclave Security Tenable Enclave Security 1.5 release. We’re excited to announce the release of Tenable Enclave Security 1.5. This release includes exciting new features: Deployment assessment scanning: Quickly assess new and updated deployments before they go live, improving visibility and risk reduction during rapid delivery cycles. Expanded software composition analysis (SCA): Broaden insight into your software supply chain with deeper enumeration of third-party libraries and components, including Go, Java, PHP and unpatched vulnerabilities in container images. SecurityCenter 6.6: Now powered by PostgreSQL, the latest version enhances performance, scalability and long-term support for mission-critical environments. Policy management: New and improved experience for managing policies for CI/CD pipelines or Kubernetes clusters. For more information, review the release notes. Tenable Vulnerability Management (TVM) Tenable PCI agent scan template now available. As a result of the PCI DSS 4.x specification release, credentialed scanning is now a requirement for PCI internal scanning. In response, Tenable created the Tenable PCI Agent, which you can use to scan your network via the PCI Internal Nessus Agent scan template in Tenable Vulnerability Management. PCI DSS 4.x enables you to use a customized approach objective. Using PCI DSS 4.x, the PCI Internal Nessus Agent provides the most comprehensive view of local vulnerabilities on your systems. Please visit the Scan Settings site for more details on configuring the PCI Agent and scans. Tenable Patch Management Tenable Patch Management 9.2.967.22 (on-premises). This release features minor quality improvements and bug fixes across the platform. Server updates: Bug fixes: We fixed an issue where the Business Units by Waves column in cycle tables was empty if no deployment waves existed for the cycle owner. Modified the patch server framework component to depend on the feed server, preventing a race condition during registration. Fixed a bug where patching cycles could lose business unit information after a server restart. Improved the update process for supported platforms within existing workflows and activities during server upgrades. Client updates: Bug fixes: Change to WUAHttpServer to include a content-length header on a full GET request for a file. This resolves the Windows Server 2016 patch download issue. Tenable OT Security Tenable OT Security 4.3: Scalable visibility and control for your modern enterprise. The Tenable OT Security 4.3 release delivers powerful new features to enhance visibility and control across your operational technology (OT) environments and entire attack surface. Key updates in this release include: Scalable OT agents: Extend asset discovery to hard-to-reach areas and embedded systems, closing critical visibility gaps with lightweight, easy-to-deploy agents that leverage your existing IT infrastructure. Enhanced Tenable One data integration: Accelerate investigations and improve risk remediation with new Policy Violation Findings and richer Exposure Signals for more comprehensive Attack Path Analysis. Streamlined asset management: Benefit from a responsive Vulnerability Findings side-panel for quick investigations, custom asset tags and groups for better organization, and batch data and ruleset updates in Enterprise Manager to ensure consistent administration across distributed sites or locations. Additional user interface enhancements in v4.3: You can now search the asset serial number in the inventory Updated Sensor page navigation System Log pagination To learn more about what’s new in the latest version of Tenable OT Security, watch the latest customer update and review the release notes.

Summary Tenable is proud to announce our new integration with Cisco Meraki Dashboard. Cisco Meraki Dashboard is a centralized cloud-based platform used to manage and monitor Cisco Meraki devices. It provides a web-based interface for configuring, troubleshooting, and securing global network and IoT deployments. Tenable’s integration with the Cisco Meraki Dashboard API allows users to leverage our vulnerability management solutions against devices that are managed in their Meraki environment including security appliances, switches, routers, and other supported devices. Scope Customers using Tenable Vulnerability Management and Nessus Manager will be able to configure up to a maximum of five Cisco Meraki credentials in a single scan policy. The Cisco Meraki credential can be found under the "Miscellaneous" category of credentials. Detailed information about the integration and configurations can be found by visiting our integration documentation page in the link for Cisco Meraki. https://docs.tenable.com/Integrations.htm Plugins Plugins related to the integration can be divided into two categories; integration and supporting plugins. The integration plugins gather the credential settings, collect data from the Cisco Meraki API, and store this data for usage by the supporting plugins. Whereas supporting plugins detect the presence of Cisco Meraki devices and perform vulnerability detections against the device attributes; mainly primarily firmware. Integration Plugins Cisco Meraki Settings Cisco Meraki Data Collection Integration Status Supporting Plugins Cisco Meraki Detection Tenable Research will also release 6 initial plugins to detect Cisco Meraki versions vulnerable to several different high-impact CVEs. Please note that these plugins will require a paranoia level of 2 (“Show potential false alarms”). Impact The Nessus Scan Information plugin (plugin ID 19506) will report credentialed checks for Cisco Meraki devices through the use of the Cisco Meraki integration. Customers will see credentialed checks ‘no’ if a Cisco Meraki Device was detected while using the integration and the firmware version that we collected for the device is not configured or absent. Otherwise, customers can expect to see ‘yes, via HTTPS’ if successful. Release Date Tenable Vulnerability Management and Nessus Manager: July 3rd, 2025 Tenable Security Center: TDB
