Best antivirus for Windows 11: Guide to choosing the right software

Windows 11 is better protected out of the box than older versions of Windows, but that does not solve the biggest problem most users face: recovery. If a phishing page slips through, ransomware starts encrypting files, or your SSD fails during an update, built-in protection can only take you so far. That is why the best antivirus for Windows 11 is no longer just the one that blocks malware most aggressively. It is the one that fits how you actually use your PC and what happens if something goes wrong.

Enforcing GitHub Repository Backups with Rubrik and GitHub Actions

Your CI pipeline enforces tests, security scans, and policy checks before code hits production. But your backups? Still running on a schedule, completely disconnected from your deployments. In this video, I'll walk you through how to use Rubrik's powerful APIs to build what I'm calling "Backup as Code": a GitHub Action that triggers an on-demand Rubrik snapshot of your GitHub repository every time code is merged into the main branch. We'll look at the action code, wire it up to a live repo, and watch the whole thing run end to end.

STARDUST CHOLLIMA Likely Compromises Axios npm Package

On March 31, 2026, a threat actor used stolen maintainer credentials to compromise the widely used HTTP client library Axios Node Package Manager (npm) package and deploy platform-specific ZshBucket variants. CrowdStrike Counter Adversary Operations attributes this activity to STARDUST CHOLLIMA with moderate confidence based on the adversary’s deployment of updated variants of ZshBucket (malware uniquely attributed to STARDUST CHOLLIMA) and overlaps with known STARDUST CHOLLIMA infrastructure.

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.

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.
