SophosLabs analysts investigated WantToCry ransomware attacks that involved the threat actors abusing the Server Message Block (SMB) service for initial access and then exfiltrating files to attacker-controlled infrastructure for remote encryption. The detection surface is significantly reduced because WantToCry operates without local malware execution, and there is no post-compromise activity beyond exfiltrating files and rewriting them to disk.

An active supply chain attack has compromised 323 npm packages published under the atool npm maintainer account. The wave sweeps the entire @antv data-visualization organization alongside standalone libraries with wide independent adoption: echarts-for-react, timeago.js, size-sensor, and canvas-nest.js. With echarts-for-react pulling roughly 1.1 million weekly downloads, any project that auto-updates these packages is in scope.

Securonix Threat Research tracks TAX#TRIDENT, an active fake Indian Income Tax-themed campaign that uses three delivery paths to reach Windows endpoints. The campaign starts with fake tax assessment lures and then moves victims toward ZIP files, VBScript downloaders, or PHP-looking web endpoints that actually return script content.

A supply chain attack affecting the @antv data visualization ecosystem and related npm packages is actively spreading through the npm registry. The attack, attributed to a threat group called TeamPCP and branded as another wave of the Mini Shai-Hulud campaign, published more than 300 malicious package versions across 323 packages in a 22-minute automated burst on May 19, 2026. The packages collectively represent approximately 16 million weekly downloads.

Five years ago, enterprise ransomware risk was mostly a perimeter problem. Today it’s an identity problem, a visibility problem, and a cloud configuration problem, all at once. Hybrid work and cloud adoption didn’t just shift where people work. They fundamentally changed where ransomware attacks begin, how far they reach, and how long they go undetected.

Sophos X-Ops looks at the Atomic macOS Stealer and its capabilities Sophos Managed Detection and Response (MDR) teams recently responded to a customer incident involving an infostealer infection on a macOS host. When we investigated, we found that the infostealer appeared to be a variant of AMOS (Atomic macOS), a well-known malware family we’ve written about before. The attack began with a ClickFix-style ruse, where a user was tricked into running a terminal command.
