Wearable, Implantable and Ingestible Medical Devices Could Revolutionize Your Health Care

Wearable, Implantable and Ingestible Medical Devices Could Revolutionize Your Health Care By Kamran Sayrafian, a senior scientist in NIST’s Information Technology Laboratory

A few years ago, I heard on the news that many people were being hospitalized with a condition of excess fluid in the lungs, called pulmonary edema. It’s common in elderly patients. Pulmonary edema is dangerous and can lead to breathing difficulties and lung failure. Since it has the potential to develop suddenly, it can be a serious medical emergency.

As a NIST researcher interested in the application of technology in health care, I wondered: Is there a way to monitor this condition at home with a simple wearable device?

NIST Finalizes ‘Lightweight Cryptography’ Standard to Protect Small Devices

NIST Finalizes ‘Lightweight Cryptography’ Standard to Protect Small Devices It’s the little things that matter most, as the saying goes, and the National Institute of Standards and Technology (NIST) has got their back.

NIST’s newly finalized lightweight cryptography standard provides a defense from cyberattacks for even the smallest of networked electronic devices. Released as Ascon-Based Lightweight Cryptography Standards for Constrained Devices (NIST Special Publication 800-232), the standard contains tools designed to protect information created and transmitted by the billions of devices that form the Internet of Things (IoT) as well as other small electronics, such as RFID tags and medical implants.

Miniature technologies like these often possess far fewer computational resources than computers or smartphones do, but they still need protection from cyberattacks. The answer is lightweight cryptography, which is designed to defend these sorts of resource-constrained devices.

RECOMMENDATIONS:

We recommend the following actions be taken:

Apply the stable channel update provided by Apple to vulnerable systems immediately after appropriate testing. (M1051: Update Software)
- Safeguard 7.1 : Establish and Maintain a Vulnerability Management Process: Establish and maintain a documented vulnerability management process for enterprise assets. Review and update documentation annually, or when significant enterprise changes occur that could impact this Safeguard.
- Safeguard 7.2 : Establish and Maintain a Remediation Process: Establish and maintain a risk-based remediation strategy documented in a remediation process, with monthly, or more frequent, reviews.
- Safeguard 7.6 : Perform Automated Vulnerability Scans of Externally-Exposed Enterprise Assets: Perform automated vulnerability scans of externally-exposed enterprise assets using a SCAP-compliant vulnerability scanning tool. Perform scans on a monthly, or more frequent, basis.
- Safeguard 7.7 : Remediate Detected Vulnerabilities: Remediate detected vulnerabilities in software through processes and tooling on a monthly, or more frequent, basis, based on the remediation process.
- Safeguard 16.13 Conduct Application Penetration Testing: Conduct application penetration testing. For critical applications, authenticated penetration testing is better suited to finding business logic vulnerabilities than code scanning and automated security testing. Penetration testing relies on the skill of the tester to manually manipulate an application as an authenticated and unauthenticated user.
- Safeguard 18.1 : Establish and Maintain a Penetration Testing Program: Establish and maintain a penetration testing program appropriate to the size, complexity, and maturity of the enterprise. Penetration testing program characteristics include scope, such as network, web application, Application Programming Interface (API), hosted services, and physical premise controls; frequency; limitations, such as acceptable hours, and excluded attack types; point of contact information; remediation, such as how findings will be routed internally; and retrospective requirements.
- Safeguard 18.2 : Perform Periodic External Penetration Tests: Perform periodic external penetration tests based on program requirements, no less than annually. External penetration testing must include enterprise and environmental reconnaissance to detect exploitable information. Penetration testing requires specialized skills and experience and must be conducted through a qualified party. The testing may be clear box or opaque box.
- Safeguard 18.3 : Remediate Penetration Test Findings: Remediate penetration test findings based on the enterprise’s policy for remediation scope and prioritization.

Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. (M1026: Privileged Account Management)
- Safeguard 4.7: Manage Default Accounts on Enterprise Assets and Software: Manage default accounts on enterprise assets and software, such as root, administrator, and other pre-configured vendor accounts. Example implementations can include: disabling default accounts or making them unusable.
- Safeguard 5.4: Restrict Administrator Privileges to Dedicated Administrator Accounts: Restrict administrator privileges to dedicated administrator accounts on enterprise assets. Conduct general computing activities, such as internet browsing, email, and productivity suite use, from the user’s primary, non-privileged account.

Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc. (M1021: Restrict Web-Based Content)
- Safeguard 2.3: Address Unauthorized Software: Ensure that unauthorized software is either removed from use on enterprise assets or receives a documented exception. Review monthly, or more frequently.
- Safeguard 2.7: Allowlist Authorized Scripts: Use technical controls, such as digital signatures and version control, to ensure that only authorized scripts, such as specific .ps1, .py, etc., files, are allowed to execute. Block unauthorized scripts from executing. Reassessbi-annually, or more frequently.
- Safeguard 9.3: Maintain and Enforce Network-Based URL Filters: Enforce and update network-based URL filters to limit an enterprise asset from connecting to potentially malicious or unapproved websites. Example implementations include category-based filtering, reputation-based filtering, or through the use of block lists. Enforce filters for all enterprise assets.
- Safeguard 9.6: Block Unnecessary File Types: Block unnecessary file types attempting to enter the enterprise’s email gateway.

Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. (M1050: Exploit Protection)
- Safeguard 10.5: Enable Anti-Exploitation Features: Enable anti-exploitation features on enterprise assets and software, where possible, such as Microsoft® Data Execution Prevention (DEP), Windows® Defender Exploit Guard (WDEG), or Apple® System Integrity Protection (SIP) and Gatekeeper™.

Block execution of code on a system through application control, and/or script blocking. (M1038:Execution Prevention)
- Safeguard 2.5 : Allowlist Authorized Software: Use technical controls, such as application allowlisting, to ensure that only authorized software can execute or be accessed. Reassess bi-annually, or more frequently.
- Safeguard 2.6 : Allowlist Authorized Libraries: Use technical controls to ensure that only authorized software libraries, such as specific .dll, .ocx, .so, etc., files, are allowed to load into a system process. Block unauthorized libraries from loading into a system process. Reassess bi-annually, or more frequently.
- Safeguard 2.7 : Allowlist Authorized Scripts: Use technical controls, such as digital signatures and version control, to ensure that only authorized scripts, such as specific .ps1, .py, etc., files, are allowed to execute. Block unauthorized scripts from executing. Reassess bi-annually, or more frequently.

Use capabilities to prevent suspicious behavior patterns from occurring on endpoint systems. This could include suspicious process, file, API call, etc. behavior. (M1040: Behavior Prevention on Endpoint)
- Safeguard 13.2 : Deploy a Host-Based Intrusion Detection Solution: Deploy a host-based intrusion detection solution on enterprise assets, where appropriate and/or supported.
- Safeguard 13.7 : Deploy a Host-Based Intrusion Prevention Solution: Deploy a host-based intrusion prevention solution on enterprise assets, where appropriate and/or supported. Example implementations include use of an Endpoint Detection and Response (EDR) client or host-based IPS agent.

Threat Actors Abuse Microsoft 365 Direct Send in Phishing Campaigns

Over the last several months, security researchers have observed threat actors targeting Microsoft 365 (M365) accounts in phishing campaigns that bypass security controls. The technique allows threat actors to spoof internal M365 users and deliver emails using Microsoft Exchange Online’s Direct Send function. Direct Send lacks proper authentication and is easily exploitable, making it a desirable tactic for threat actors. Microsoft allows emails to be sent using Direct Send by default if the emails are sent from the organization’s accepted domain.

Microsoft 365 administrators can implement “Reject Direct Send” to block unauthenticated Direct Send traffic at the tenant level. Direct Send may also be disabled using PowerShell. In addition to disabling Direct Send, the NJCCIC recommends following Microsoft’s Email Security Best Practices for M365, including identifying SPF/DKIM/DMARC failures, use authenticated SMTP client submissions or SMTP relay with specific IP restrictions, implement strict DMARC policies, configure SPF to hardfail, and enforce MFA for M365 accounts.

Comment Now: NIST NCCoE Chatbot Internal Report

The NIST National Cybersecurity Center of Excellence (NCCoE) has re-issued NIST Internal Report (IR) 8579, Developing the NCCoE Chatbot: Technical and Security Learnings from the Initial Implementation. Originally published in June, the document was revised to improve the document’s demonstration of the enhanced abilities of an RAG-based LLM tool over a generic LLM.

The public comment period for the publication has been extended and will close on September 11, 2025.

The NCCoE identified a potential application for a chatbot to support its mission and developed a secure, internal-use chatbot to assist NCCoE staff with searching and summarizing cybersecurity guidelines tailored to specific audiences or use cases.

The chatbot was built using retrieval-augmented generation (RAG)-based LLM technology. This approach combines techniques from information retrieval and natural language generation, enabling the chatbot to provide more focused, contextually relevant responses by leveraging a repository of cybersecurity knowledge, including previous NCCoE publications. Compared to search engines, LLM-based chatbots provide more contextually relevant and precise responses by understanding the nuances of natural language queries.

This report provides a point-in-time examination of the NCCoE Chatbot, outlining the NCCoE’s approach to developing the tool, as well as the NCCoE’s response to specific security challenges. In addition, this report provides an overview of the chatbot and its supporting technologies so that other organizations might consider the benefits of their use.

We encourage you to review this document and provide comments by September 11, 2025. If you have any questions, please email the team at nlp-nccoe@nist.gov.

Russia Cyber Threat Operations

Russian nation-state cyber actors remain among the most persistent, capable, and strategically aligned threats in the global cyber landscape. Their operations routinely target Western governments, critical infrastructure, defense contractors, and political institutions, using a combination of cyber espionage, advanced malware, and living-off-the-land techniques. These campaigns are characterized by prolonged presence, covert operations, and strategic alignment with Russia’s geopolitical goals, making them especially challenging to detect and mitigate.

A key takeaway from this analysis is that Russian cyber activity is not merely opportunistic; it is intentional and ongoing, designed to maintain persistent access for future disruption, espionage, or influence efforts. Russia’s ability to blend into trusted environments and exploit legitimate platforms significantly raises the threat to national security, essential services, and the private sector.

In the broader risk context, Russia exemplifies the intersection of cyber operations and hybrid warfare, where espionage, sabotage, and geopolitical strategy align. Organizations must prioritize detection and hardening against known Russian tactics, techniques, and procedures (TTPs), particularly those involving credential theft, cloud environment exploitation, and lateral movement, as these remain core elements of Russia’s offensive cyber strategy.

Key Points

Who: Russian state-sponsored actors, including APT28 (Fancy Bear), APT29 (Cozy Bear), Sandworm, and Gamaredon.
What: Conducted cyber espionage, prepositioned in networks, and launched disruptive operations aligned with Russian geopolitical goals.
How: Used spearphishing, credential harvesting, zero-day exploits, cloud service abuse, and stealthy tools like living-off-the-land binaries (LOLBins) and custom malware.
Why it matters: These operations are designed not only for data theft but also to maintain persistent access, evade detection, and retain the ability to disrupt critical infrastructure or manipulate information at strategic moments.

Risk Assessment

The NJCCIC has assessed that Russian state-sponsored cyber actors represent a persistent and evolving threat with the demonstrated capability and intent to conduct both intelligence-gathering and disruptive operations. Their activities seriously threaten national security, essential public services, and critical industries.

Recently, these groups have changed tactics by increasingly targeting cloud infrastructure and identity management platforms like Microsoft 365. This evolution includes deploying new malware variants designed to evade traditional detection methods, allowing them to infiltrate previously considered lower-risk environments.

Russian actors have a well-documented history of targeting entities across government, critical infrastructure, healthcare, defense, and election systems. The likelihood of exposure or compromise is significantly higher if environments include legacy technology or commonly used third-party platforms. The combination of their strategic intent, advanced techniques, and a sector’s relevance makes proactive defense and visibility into these threat vectors essential.

Capabilities

Advanced Persistent Threats (APTs): Russia maintains multiple state-sponsored groups (APT28, APT29, Sandworm) capable of long-term, covert operations across sectors.
Malware Toolsets: Known for deploying malware such as NotPetya, Snake, Drovorub, WellMess, and CosmicDuke.
Tradecraft: Uses living-off-the-land binaries (LOLBins), legitimate credentials, and cloud platform abuse (Microsoft 365).
Operational Focus: Supports espionage, prepositioning in critical infrastructure, disinformation, and destructive attacks aligned with geopolitical goals.
Supply Chain Intrusions: Demonstrated ability to compromise software providers and abuse trusted relationships (SolarWinds, Ukrainian tax software).
ICS/OT Disruption: Proven capacity to target and impact operational technology systems (BlackEnergy, Industroyer).
Information Warfare: Coordinates cyber operations with disinformation and influence campaigns targeting elections and public opinion.

Key Intelligence Gaps

The NJCCIC has assessed that several intelligence gaps limit a full Russian cyber threat landscape assessment. One of the most pressing concerns is whether Russian threat actors are currently positioning themselves within networks to carry out future physical or disruptive attacks, particularly amid ongoing geopolitical tensions and hybrid warfare strategies.

Another critical intelligence gap concerns developing and deploying new malware strains, particularly malware designed to target industrial control systems (ICS), satellite infrastructure, or emerging space technologies, where visibility remains low.

The degree of coordination between Russian intelligence services and non-state criminal cyber groups (such as ransomware-as-a-service operators) also remains unclear. It is essential to determine how much operational freedom these groups have and whether they receive explicit support or protection from the state. There is also a lack of clarity about whether Russia’s agencies are working together or against each other.

Additionally, there is limited insight into evolving Russian tactics for evading detection, especially in hybrid and multi-cloud environments, where traditional monitoring tools may fall short.

The impact of economic sanctions and wartime constraints on Russia’s cyber strategy and operational capabilities is also poorly understood, leaving a gap in forecasting future shifts in tactics or targeting priorities.
