ほぼ毎週当社のマルウェア検出システムは、npmやPyPIなどの公開レジストリ全体で、数千もの新規および更新されたパッケージをスキャンしています。今週も例外ではありませんでした。
We confirmed over 130 malicious packages between June 7 and June 12, 2026, predominantly across npm, with additional cases in PyPI. Several appeared in coordinated clusters, repeated malicious releases published under the same names or across closely related package families.
今週の注目すべき事例は sensivityは、2.5.x 範囲で 40 を超えるバージョン付きリリースを npm に大量に送り込み、複数日にわたって確認された。その他の注目すべきクラスターには、 @solana-labs typosquats targeting the Solana ecosystem (web3.js, web3-js, etherjs, spl-toke, ancor, web3js — across two separate publishing campaigns on Jun 7 and Jun 8), the @nstrlabs family (sdk, ixel, utils, shared-components, api-client, auth — dependency confusion attack against an internal package namespace), the @klapp-login-platform group (native-sdk, oidc, routes — impersonating an authentication platform), internallib_v557 (NAIST) と internallib_v984 （難読化された内部ライブラリの偽装の複数のバージョン） pocteszep （6月11日に6バージョン公開）および、以下を含む暗号およびWeb3ユーティリティのクラスター blockchain-helper-0, ethereum-kit-1, ethereum-kit-9, crypto-utils-7, wallet-sdk-9, defi-tools-39, swap-sdk-87, farming-tools-12を選択します。 morningstar-design-system package appeared in three versions on Jun 10, impersonating a well-known financial design system. In PyPI, helixagentai, telegramlite, cdjeez 今週中に確認された。
These were not isolated anomalies. What stood out this week was the concentration of dependency confusion attacks against internal package namespaces, the sustained multi-day publishing of the sensivity cluster, and the continued targeting of Web3 and Solana tooling, a pattern that has accelerated significantly in 2026.
この週次スナップショットは、継続的な悪意のあるコードダイジェストの一部であり、新しい脅威を検証し、DevSecOps チームが自社を保護するのに役立つ実用的な情報を提供します。 pipeline損傷が発生する前に。
今週判明した内容と、それがなぜ重要なのかを詳しく見ていきましょう。
Don’t Let Malicious Packages Reach Production
The packages your teams depend on are increasingly being used as an entry point. Xygeni早期マルウェア検出 monitors registries in real time, so threats like the ones in this week’s digest are blocked before they ever reach your builds.
This week’s findings are a reminder that the tactics are getting more deliberate. Version flooding, namespace impersonation, and multi-day coordinated campaigns are not edge cases anymore, they are standard attacker playbook. One-time scans and manual audits cannot keep pace with campaigns that publish dozens of versions across multiple days and registries simultaneously.
ザイジェニの Open Source Security solution gives your DevSecOps teams continuous visibility across npm, PyPI, and beyond,detecting harmful packages at the moment of publication, prioritizing what poses real exploitable risk, and shortening the path from detection to remediation. So your teams can ship fast without compromising on security.
