Benvido ao June edition of the Xygeni Malicious Code Digest. This month, our security research team confirmed more than 645 paquetes maliciosos across npm, PyPI, and (for the first time) the VSCode extension marketplace.
June was defined by three converging trends: sustained version-flooding campaigns designed to outlast blocklists, a sharp acceleration in attacks targeting AI tooling and agentic development workflows, and coordinated dependency confusion attacks against internal monorepo namespaces.
Among the most notable campaigns documented this month:
- sensibilidade flooded npm with over 70 versions across the 2.5.x range, a sustained evasion campaign republishing continuously to stay ahead of takedowns.
- A two-wave Solana typosquat campaign (June 7–8) published 15 packages impersonating
@solana-labsecosystem tooling, targeting Web3 and DeFi developers directly. - houzidawang806 accounted for over 25 versions in a single day (June 13), joined by metrics-pipeline-d8k2 republished across 21 versions between June 15–18.
- o CryptoDAO Confusion campaign (June 17) published 11 packages at version 99.99.99, each carrying an identical postinstall payload sweeping CI/CD tokens, cloud credentials, and crypto wallet secrets.
- The week of June 20–26 brought the most concentrated AI tooling targeting of the month: axudantes de ollama (20 versions), axudantes-de-axentes-de-openai (23 versions), monoclaude, axudantes-ai-sdke @langgraphjs/toolkit, all confirmed in a single week, directly targeting Ollama, OpenAI agents SDK, LangGraph, and Claude API integrations.
- Two confirmed malicious VSCode extensions appeared this month, signaling that attackers are expanding beyond package registries into the developer environment itself.
The defining pattern of June: attacks are moving into IDE extensions, AI agent tooling, and agentic workflows where a malicious package installed autonomously has no human reviewer between infection and execution.
This monthly update is part of Xygeni’s ongoing malware and supply chain threat research initiative. For full context across every malicious package confirmed this month, explore the complete June Malicious Code Digest and related research from the Xygeni Security Team.

Stop Malicious Code Before It Reaches Your Pipeline
Software supply chain threats have moved well past theoretical. Dependency confusion attacks, credential stealers, AI-targeted malware, and poisoned developer tooling are hitting real teams in real SDLCs every week.
Xygeni's detección de software malicioso supply chain security platform gives organizations the visibility to catch malicious dependencies before they execute on a developer machine, enter a build system, or reach production. Coverage spans npm, PyPI, VSCode, and beyond, monitoring for suspicious publishing patterns, namespace abuse, typosquatting, and AI-native attack techniques as they emerge.
Every finding is automatically prioritized by exploitability, reachability, and business impact, so your team focuses on what actually needs fixing, not noise.
Whether it’s a malicious open-source package, a compromised developer tool, or an AI-generated code risk, Xygeni keeps security and engineering teams one step ahead of the supply chain threat landscape.
