Ransomware in Healthcare: It's Disruption, Distraction, and Data Theft

Ransomware attacks are about disruption, distraction, and data theft happening at the same time. Nelson Carreira breaks down how modern threat actors operate. While one attack disrupts operations, another may be quietly exfiltrating sensitive data. That complexity is why healthcare organizations must prepare for recovery environments that allow clinical operations to continue safely while production systems are rebuilt.

AI Takes Over RSAC Conference (Now What?) with Dave Bittner

In this RSAC 2026 Conference recap, Dave Bittner, Host of the CyberWire Daily podcast, joins Data Security Decoded host Caleb Tolin from the guest seat to discuss the biggest theme dominating the conference: artificial intelligence, and, more specifically, agentic AI. From wall-to-wall AI messaging across San Francisco to in-depth conversations with security leaders and analysts, one thing became clear: the industry has moved past debating whether AI will take hold. It already has. Now, the focus has shifted to making it safe.

Poisoned Axios: npm Account Takeover, 50 Million Downloads, and a RAT That Vanishes After Install

On March 30-31, 2026, threat actors published two malicious versions of the popular HTTP library axios (versions 1.14.1 and 0.30.4) to the npm registry. Both versions included a new dependency named plain-crypto-js which, in its 4.2.1 release, contained a fully-featured cross-platform dropper that silently installed a Remote Access Trojan (RAT) on developer machines.

Emerging Threat: Axios npm Supply Chain Attack Drops Remote Access Trojan (RAT)

On March 31, 2026, two malicious versions of axios were published to npm, , using credentials stolen from a lead axios maintainer. The attacker injected a hidden dependency into both releases that drops a remote access trojan (RAT) on any machine that ran npm install during the exposure window. No CVE identifier has been assigned at the time of writing. The malicious dependency executes automatically at install time via a postinstall hook, without any action by the developer.

The State of Ransomware in Financial Services 2025

369 IT and cybersecurity leaders reveal the ransomware realities for financial services providers today. The report examines how the causes and consequences of ransomware attacks on financial services providers have evolved over time. This year's edition also sheds light on previously unexplored areas, including the organizational factors that left providers exposed and the human toll ransomware takes on IT and cybersecurity teams in the financial services sector.

Why Incident Response Fails (And It's Not the Technology)

Incident response plans rarely fail because of technology. It’s usually because of coordination, or the lack of. Nelson Carreira explains why organizations that build isolated recovery environments should use them not only for recovery testing but also to strengthen incident response planning. Simulation exercises reveal a critical need: clear roles, leadership authority, and secure communication channels during a crisis.

Cyber Resilience in Healthcare: Why Recovery Starts at the Endpoint

On this episode of Building Cyber Resilience: A Healthcare Leader’s Guide, Nelson Carreira explains why recovery planning in healthcare has to consider the entire environment, from user devices to network architecture. In large incidents, the blast radius can extend far beyond servers, sometimes forcing organizations to rebuild tens of thousands of endpoints before operations can safely resume. As he puts it.

How to protect yourself from ransomware

• Ransomware complaints filed with the FBI rose 9% in 2024; the FBI describes ransomware as the most pervasive threat to critical infrastructure (FBI IC3 2024 Annual Report). • The average ransom payment reached $2 million in 2024 — a fivefold increase from 2023 — while recovery costs averaged $2.73 million excluding any ransom paid (Sophos State of Ransomware 2024).

What Happens When Healthcare Systems Go Dark

The AI Malware Surge: Behavior, Attribution, and Defensive Readiness

Over the last year, AI-assisted malware development has evolved from an experimental practice into a common part of the attacker toolkit. In a rolling window from February 2025 to February 2026, Arctic Wolf Labs observed over 22,000 distinct files triggering AI-focused YARA rules across multiple malware repositories. These files included AI-generated code, large language model (LLM)-style scaffolding, runtime AI API integration, and DeepSeek-derived artifacts.

Analyzing FAUX#ELEVATE: Threat Actors Target France with CV Lures to Deploy Crypto miners and Infostealers Targeting Enterprise Environments

Securonix threat researchers have been tracking an ongoing campaign targeting French-speaking corporate environments through fake resumes. The campaign uses highly obfuscated VBScript file disguised as resume/CV documents, delivered through phishing emails. Once executed, the malware deploys a mutli-purpose toolkit that combines credential theft, data exfiltration, and Monero cryptocurrency mining for maximum monetization.

TeamPCP Supply Chain Attack Part 2: LiteLLM PyPI Credential Stealer

Part 1 covered CanisterWorm, the self-spreading npm worm. This post covers the next wave: a malicious LiteLLM PyPI package carrying the most capable credential stealer TeamPCP has deployed yet. On March 24, 2026, two versions of litellm, one of the most widely used Python libraries for working with AI language model APIs, were published to PyPI carrying a hidden credential stealer. Versions 1.82.7 and 1.82.8 never appeared on the official LiteLLM GitHub repository.

BewAIre: Detecting Malicious Pull Requests at Scale with LLMs

As AI coding assistants accelerate software development, the volume of pull requests at Datadog has grown to nearly 10,000 per week, increasing the risk that malicious changes slip through due to review fatigue. To address this, Datadog built BewAIre, an LLM-powered code review system designed to identify malicious source code changes introduced by threat actors. By reducing approval fatigue for developers while increasing friction for attackers, BewAIre guides human reviewers to the areas where judgment matters most, without slowing developer velocity.

CanisterWorm: The Self-Spreading npm Attack That Uses a Decentralized Server to Stay Alive

On March 20, 2026 at 20:45 UTC, Aikido Security detected an unusual pattern across the npm registry: dozens of packages from multiple organizations were receiving unauthorized patch updates, all containing the same hidden malicious code. What they had caught was CanisterWorm, a self-spreading npm worm deployed by the threat actor group TeamPCP. We track this incident as MSC-2026-3271.

Camille Stewart Gloster on how AI systems can help you wade through log data and get more done

AI and machine learning are already being used in cybersecurity to help reduce the "noise of all the indicators" that security teams receive. These systems can serve as a "first line of defense" by setting up potential response actions. However, organizations need to ensure they keep human analysts in the loop because contextual knowledge and human judgment remain critical. Data Security Decoded is available on our YouTube channel!

Cato CTRL Threat Research: Vishing and Microsoft Teams Used to Deliver PhantomBackdoor

Cato CTRL has discovered a q-based delivery technique used against an Italy-based consumer services company associated with PhantomBackdoor, a multi-stage WebSocket-based backdoor previously reported in a Ukraine-focused spear phishing operation by SentinelOne. In SentinelOne’s earlier reporting, initial access relied on phishing lures and a ClickFix-style flow that triggered a staged PowerShell and ended with a WebSocket backdoor.

fast-draft Open VSX Extension Compromised by BlokTrooper

The KhangNghiem/fast-draft extension, listed on open-vsx.org/extension/KhangNghiem/fast-draft and now sitting above 26,000 downloads, had multiple malicious releases that execute a GitHub-hosted downloader and pull a second-stage RAT and infostealer from the BlokTrooper/extension repository. The confirmed malicious releases in the version line we inspected are 0.10.89, 0.10.105, 0.10.106, and 0.10.112.

Glassworm Strikes Popular React Native Phone Number Packages

On March 16, 2026, two React Native npm packages from the AstrOOnauta were backdoored in a coordinated supply chain attack. Both releases added an identical install-time loader that fetches and executes a multi-stage Windows credential and crypto stealer, triggered by nothing more than a routine npm install. The affected packages are react-native-country-select@0.3.91 and react-native-international-phone-number@0.11.8.

What Healthcare Leaders Face After a Cyberattack

In this episode of Building Cyber Resilience: A Healthcare Leader’s Guide, host Josh Howell speaks with Errol Weiss, Chief Security Officer at Health-ISAC. Drawing on decades of experience across government, finance, and healthcare, Errol walks through what leaders actually face in the hours and weeks following a cyberattack. The conversation explores why healthcare remains a top ransomware target, how uncertainty shapes recovery decisions, and why trusted, anonymous information sharing has become one of the sector’s strongest defenses.

What is Agentic AI vs GenAI?

Everyone knows ChatGPT, but Agentic AI is where the real work happens. In this Agentic AI vs GenAI breakdown, we explain why Agentic AI is the next major leap, and what it means for your business and career. Here’s the difference: Generative AI (GenAI): Creates content. You ask, it writes, summarizes, or creates. Agentic AI: Does work. It is built on three core components: a brain (reasons), memory (context), and tools (the key that lets agents touch real systems like APIs and databases).

Ransomware Attacks Surge by 50% Even as Payments Drop

The number of ransomware attacks increased by 50% in 2025, even though the number of victims who decided to pay the ransom fell to an all-time low, according to a new report from Chainalysis. The size of the ransom for victims who did pay increased significantly, growing 368% year-over-year to nearly $60,000. The total ransom payments observed by Chainalysis last year amounted to $820 million.

Polymorphic Viruses and Their Impact on Cybersecurity

A polymorphic virus is one of the hardest types of malware to detect because it can change into different forms. Because these advanced threats can modify their code in specific ways, they are very hard for standard signature-based antivirus systems to detect. Polymorphic viruses, on the other hand, use dynamic code encryption and mutation engines to alter their code structure, making them even harder to detect. The need for strong defenses has never been greater as hackers continue to use these methods.

Daniel dos Santos on defending against opportunistic cyberattacks

Complicated, targeted attacks aren’t the only methods you should be on the lookout for. Security fundamentals are important for defending against opportunistic that can cause chaos! On this episode of Data Security Decoded, Daniel dos Santos (VP of Research, Forescout Technologies) and host Caleb Tolin explore attacker motivations, common entry points, and what defenders must prioritize now.

Why Infostealers Are Central to Third-Party Breaches: A Look at the Top Malware Targeting Your Vendors

When threat actors compromise your vendors, they are rarely aiming for a single, isolated win. They are looking for leverage. Every third party represents a potential force multiplier: a trusted connection, a shared platform, a pathway into multiple downstream environments. We recently looked at the vulnerabilities that are most commonly being used against vendors, but vulnerabilities alone don’t tell the full story.

AI Moves Fast, Privacy Has to Move Faster with Ojas Rege

In this episode, Caleb Tolin welcomes Ojas Rege of OneTrust for a practical, wide-ranging conversation on how data privacy and governance must evolve alongside enterprise AI adoption. Ojas explains why AI fundamentally changes the privacy conversation: the same systems that enable organizations to move faster can also cause harm faster when guardrails aren’t in place. From agentic AI systems that dynamically repurpose data to general-purpose models that blur traditional notions of “intended use,” the challenge isn’t just compliance—it’s trust.

SloppyLemming Deploys BurrowShell and Rust-Based RAT to Target Pakistan and Bangladesh

Between January 2025 and January 2026, Arctic Wolf tracked an extensive cyber espionage campaign that we assess was conducted by SloppyLemming (also known as Outrider Tiger and Fishing Elephant), an India-nexus threat actor, targeting government entities and critical infrastructure operators in Pakistan and Bangladesh.
