Flagging an important warning from the FBI / IC3, and sharing resources to help you assess and reduce risk. Alert Number: I-082025-PSA - Russian Government Cyber Actors Targeting Networking Devices, Critical Infrastructure The High-LevelThe FBI is alerting that Russian FSB cyber actors (aka Center 16 / “Berserk Bear” / “Dragonfly”) are actively exploiting a known vulnerability in Cisco Smart Install (SMI) — CVE-2018-0171 — to target networking devices globally. These actors are using SNMP (especially older/insecure versions v1 and v2) and unpatched / end-of-life devices to:Collect configuration files. Modify configs to insert or enable unauthorized access. Do reconnaissance inside victim networks, with particular interest in protocols & applications used in critical infrastructure / industrial control systems.The vulnerability and use of legacy/unsecured protocols make aging equipment especially risky. Even if a device is not directly breached, weak practices may allow attackers in

This NQE extracts the config for each ACL, accounting for all syntaxes used in Cisco devices. The order is determined by the line number, which is used to compare the line of the deny statement with the last line of the ACL config and returns the failures by device and ACL name.standard(config) = foreach match in patternMatches(config, `access-list {aclName:string} {!"remark"}`) group match.line as config by match.data.aclName as name select { name, config };nested(config) = foreach match in patternMatches(config, `ip access-list {string} {name:string}`) let config = (foreach line in match.line.children where !hasMatch(line.text, re`.*remark.*`) select line) select { name: match.data.name, config };foreach device in network.devicesforeach acl in standard(device.files.config) + nested(device.files.config)let maxLine = max(foreach line in acl.config select line.lineNumber)foreach line in acl.configwhere hasMatch(line.text, re`.*deny\s*ip any any.*`) &&

Hello:   Hopefully this isnt a repeat as i couldn’t find the answer on here so I wanted to post it.  im trying to match against “tags” within  the application, and everything I am tying, regarding the ‘where matches” command is used, isnt working.  This is in the regular inventory so i have the statement “foreach device in network.devices” list as well above where i think the match line should go.  I can it list the tags, just not match/filter on tags.

Avoiding device management being exposed on interfaces to the internet is something that we all want to avoid, but if such an exposure was to occur wouldn’t you want to know?This query inspects all interfaces and specifically checks whether http, https, fgfm (FortiManager), snmp, and SSH are enabled via the set allowaccess command.  To run this check you’ll need to configure a custom command.Custom Command Required.show system interfacesThe Query:/** * @intent Do not present fgfm, SSH, HTTPS on the internet ports * @description Check all interfaces that face the internet to ensure * "SSH","HTTPS" and "fgfm" are not present. Example Interface: edit "mgmt1" set vdom "root" set ip 169.254.255.2 255.255.255.255 set allowaccess ping https ssh snmp set status down set type physical set dedicated-to management set role lan set snmp-index 1 next */ifacePattern = ```config system interface edit {ifaceName:string} set ip

This is to discuss a common practice with the use of the interface Description field.It is really common to look at CDP or LLDP and find the neighbor device name, then put that remote device name into the interface Description of the interface that connects these two devices together.  It is also common to add the remote device interface as well./** * @intent Verify if the interface description includes the device name of the linked device * @description Use the Link element of the data model to determine the device name and interface * of a networking device that is connected to this interface. * Verify that the remote device name and remote interface an included in the interface Description. */export getL3Interfaces(device: Device) =  foreach iface in device.interfaces  where length(iface.links) > 0  foreach ifaceIpInfo in getSvis(iface) + getSubIfaces(iface)  select {    name: ifaceIpInfo.name,    adminStatus: ifaceIpInfo.adminStatus,    operStatus: ifaceIpInfo.operStatus,    ipv

If you’ve ever waded into the world of cybersecurity, you’ve probably run across the acronyms CWE, CVE, and KEV. They sound similar, and they’re all related to security flaws — but each serves a different purpose. Here’s a clear breakdown: CWE (Common Weakness Enumeration)Think of CWE as a blueprint of mistakes. Maintained by MITRE, CWE is a catalog of weakness types — ways that software or hardware can go wrong. A CWE is not tied to a single product; instead, it describes a class of design or coding errors. CWEs can be abstract (like “improper input validation”) or very specific (like “integer overflow in arithmetic operations”). Example: CWE-269 (Improper Privilege Management), which outlines the general problem of failing to correctly enforce privilege levels.  CVE (Common Vulnerabilities and Exposures)CVE zooms in from the abstract to the concrete and specific. A CVE is an actual, identified vulnerability in a particular product or version. Every CVE entry includes metadata

Chinese state-sponsored threat actors are targeting network infrastructure worldwide, leveraging compromised routers and edge devices to establish long-term persistence and exfiltrate sensitive data. A recent joint cybersecurity advisory from NSA, CISA, FBI, and international partners highlights the scale of this threat and provides detailed mitigation guidance.At Forward Networks, we’ve created a purpose-built NQE query to help customers quickly identify two of the most common risks associated with this campaign:Known exploited vulnerabilities used by the threat actors to gain initial access   Permissive ACLs that may allow traffic to flow to attacker-controlled IP addresses  Why this threat mattersThe campaign—tracked in industry reporting under names such as Salt Typhoon and RedMike—isn’t limited to a single vendor or region. Attackers embed themselves in network devices, sometimes at ISPs or providers, then use those footholds to:Steal authentication information by redirecting TACA

As part of my onboarding with Forward Networks, I’ve been exploring its native dashboarding capabilities. While the built-in dashboards offer useful insights, I’m not fully convinced they’ll meet the specific reporting needs of our leadership team.To address this, I’m evaluating two integration options:SharePoint: Using the Forward API to retrieve and transform data, then render dashboards tailored to our requirements directly within SharePoint. Grafana Cloud: If SharePoint proves limiting, I’ll explore leveraging our existing Grafana Cloud instance for more flexible visualization.Has anyone integrated Forward with either platform? I’d really appreciate any experiences, suggestions, or recommendations.Below is the format I think supports the SLT teams requirements.Thanks for any feedback. 

OverviewWorking with IP addresses in NQE opens up all kinds of possibilities, but it’s not always clear what tools are available out of the box. I’ve worked with several customers who wanted to do everything from filtering IPv6 neighbors to calculating subnet utilization across thousands of devices—and the good news is, NQE makes a lot of this simpler than you might expect.In this post, I’m sharing five of my favorite IP address-related techniques that you might not know about, along with tips for using them in your own queries. 1. Use toNumber() to Compare IP AddressesWhen you want to compare IP addresses (e.g., sort them, find the lowest one, etc.), you can use toNumber() to convert each address into a numeric value.Note that this can only be applied to an IPv4 address.toNumber(10.1.2.3) // Converts to an integer based on its position in the full IPv4 rangeThis is useful for identifying router IDs or evaluating address ranges, especially when you don’t know in advance how the addres

Curious about AWS but not sure where to start? In this step-by-step walkthrough, I’ll show how to set up your own AWS Free Tier account, configure billing safeguards, and follow best practices for security and user management. Whether you’re preparing for certifications or just experimenting with cloud services, this guide will help you get started with confidence.   Cloud infrastructure has become essential in today’s IT landscape, and gaining hands-on experience with AWS (Amazon Web Services) is a valuable step for any engineer. The AWS Free Tier allows you to experiment with building, using, and tearing down AWS services at little to no cost—an excellent way to learn without breaking the budget.In this article, I’ll walk you through: Why you might want to create an AWS Free Tier account How to set one up safely Best practices for billing, security, and user management How to clean up or close your account when you’re done  Why Use AWS Free Tier?Creating your own AWS Free Tier

In dynamic network environments, engineers often make quick changes directly to a device’s running configuration to resolve issues or apply updates. But if those changes aren’t saved to the startup configuration, they’ll be lost on the next device restart—potentially causing outages or security gaps.This oversight can lead to:Devices booting with outdated configurations   Outages and service disruptions   Security vulnerabilities if critical policy changes aren’t retained  Manually verifying that all running configs are saved can be time-consuming and error-prone, especially in large environments. Forward Networks’ Network Query Engine (NQE) simplifies this process by automatically comparing the running and startup configurations across devices in your network.PrerequisitesAccess to Forward Enterprise with NQE enabled   Cisco devices modeled in Forward Networks   Network Admin role to create custom commands   Add the following Custom Commands (requires Network Admin Role) show startup-

Forward NQE includes several under-the-hood optimizations that can improve query performance. This post focuses on the _lookup optimization, which can reduce execution time when filtering on a single key field using an exact equality comparison. Leveraging _lookup is considered a best practice whenever possible.In a recent query I wrote joining device CVE information with the EPSS database in a network containing 10,000 devices, re-writing the NQE to take advantage of _lookup reduced the execution time by over 50%. While this kind of optimization isn’t as dramatic as parallelization—where a multi-minute query might drop to seconds—it can still offer a significant and worthwhile improvement, particularly in queries with repeated key-based lookups over large lists. What _lookup DoesNormally, when you write a loop in NQE that scans a list for a match, the query engine will iterate over every item in that list and check the condition. This can be slow if the list or number of devices in th

When an NQE runs in parallel, it executes the same logic across all devices in the snapshot inventory simultaneously, rather than one device at a time in sequence. In practice, this can be the difference between a query that risks hitting the 20-minute timeout and one that completes in a fraction of the time. When Parallelization HappensA query will run in parallel if:It starts with an iteration over network.devices It does not access network.devices in any other way (only one iteration) It does not access network.endpoints It does not use the group … by qualifierHow to CheckFrom the NQE IDE:Windows: Alt + left-click Execute Mac: Option + left-click ExecuteIn the debug panel, look for:parallel_foreach device in network.devicesIf you only see foreach device in network.devices, it’s not parallelized.Example 1 — Pass the Device Object, Not Its Name Broken (serial)Passing device.name into a function and then re-looking up the device causes a second iteration over network.devices.getDeviceV
