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.

Fudo Security API v2 Compatibility
Summary Tenable is proud to announce compatibility with Fudo API v2. Customers now have the option to use both the API v2 and API v1 of the Fudo Security Privileged Access Management (PAM) solution. The API v2 uses API key authentication and not username and password, so customers using the integration credential now have a field for API URL and API Key. Further information regarding these changes and other helpful configuration tips for scans can be found by following the provided link to the FUDO section of Tenable's documentation page. Impact Existing scan configurations remain unaffected. Customers utilizing the integration will observe that the integration collects identical information, irrespective of the API version employed. Target Release Date 09/16/2025 for TVM and Nessus, TBD for SC
Introducing Enhancements to VPR in Tenable Vulnerability Management!
Today, we launched enhancements to Vulnerability Priority Rating (VPR) in Tenable Vulnerability Management. These updates provide unmatched precision, AI-driven insights, and contextual understanding to help your security teams prioritize and remediate vulnerabilities more efficiently. How this benefits you: Sharpen precision to focus on what matters most: While traditional CVSS scores classify 60% of CVEs as High or Critical, our original VPR reduced this to 3%. The enhanced VPR further refines this, helping your teams focus on just 1.6% of vulnerabilities that represent actual risk to your business. This is achieved by leveraging an even broader spectrum of threat intelligence and real-time data input used to predict near-term exploitation in the wild. Unlock AI-driven insights and explainability: Our new LLM-powered insights deliver instant clarity, helping you quickly understand why an exposure matters, how it has been weaponized by threat actors, and providing clear, actionable guidance for mitigation and risk reduction. Prioritize with industry and regional context: New metadata provides crucial context, helping you understand if a vulnerability is being targeted in your specific industry or geographic region. Leverage advanced querying & filtering: The enhanced VPR model is easily accessible for filtering and querying in the new Explore views, which display Assets and Findings data, enabling faster investigations and response workflows. Both the original VPR and the enhanced VPR (referred to in-product as 'VPR (Beta)') will coexist for a period of time in Tenable Vulnerability Management, ensuring you can make a smooth transition. Future deprecation of the original VPR will be communicated in advance. To learn more about the enhancements to VPR, see the solution overview and click-through demo. For additional information, see our FAQ, release notes, and Scoring Explained help documentation.Include/Exclude Path and Tenable Utils Unzip added to Log4j Detection
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, 2025Nutanix Prism v4 API Compatibility
Summary Tenable is proud to announce compatibility with the version 4 of the Nutanix Prism Central REST API. This provides compatibility with current and future versions of Nutanix Prism. Change Tenable is adding support for API v4 but preserving support for API v3. Customers for whom API v4 is not available will continue to use v3. For all other customers, Tenable’s Nutanix Prism integration will automatically use API v4. Impact Customers should not see scan results change. The integration collects the same information regardless of the API version in use. Customers with Nutanix Prism Central are encouraged to update plugins to utilize the latest version of the integration. Target Release Date 26 Aug 2025 for T.VM, Nessus, and T.SC.Excluding 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. Plugins 178772 - Node.js Modules Installed (Linux / Unix) 190687 - NuGet Installed Packages (Linux / Unix) 164122 - Python Installed Packages (Linux / Unix) 207584 - Ruby Gem Modules Installed (Linux / Unix) Target Release Date September 3, 2025
