ダークトレースは、React2Shellの脆弱性をエクスプロイトするAI/LLM生成によるマルウェアを自社のCloudypots環境内で検知しました。この事例は、LLM（Large Language Model：大規模原語モデル）支援の開発によって低スキルの攻撃者であっても効果的なエクスプロイトツールを迅速に作成できることを示しています。このブログではその攻撃チェーンとAIで生成されたペイロードを分析し、容易に入手可能なAIサイバー脅威がもたらす、防御上の問題の深刻化について解説します。

This blog explores a macOS phishing campaign that leverages social engineering, AppleScript loaders, and attempted abuse of the macOS’ TCC feature to gain privileged access. It highlights a broader trend: attackers increasingly exploit user trust rather than system vulnerabilities, using staged payload delivery and persistence techniques to maintain long‑term access.

his blog details how to unpack malware like SnappyBee, a modular backdoor linked to Salt Typhoon, revealing its custom packing, DLL sideloading, dynamic API resolution, and multi‑stage in‑memory decryption. It provides analysts with a step‑by‑step guide to extract hidden payloads and understand advanced evasion techniques by sophisticated malware strains.

Darktrace detected a potential ClearFake‑related incident involving signs of EtherHiding activity and interactions with blockchain‑based infrastructure. A single device showed repeated suspicious command‑line behavior, primarily involving Microsoft HTML Application Host. The activity occurred over the course of a day and indicated early‑stage attempts to load malicious content associated with the ClearFake campaign.

Financial institutions are facing a threat landscape shaped by identity-led intrusion, pre-disclosure exploitation, data-first ransomware, and growing cloud and AI governance blind spots. This blog explores the key threats and trends redefining cyber risk across the finance sector and what defenders must adapt to next.

Cybersecurity is no longer just an IT concern, but a business imperative shaped by AI-driven threats and accelerating risk. In this blog, Amel Edmond, CIO at the advisory, tax, and audit firm Withum, discusses his perspective on why AI is essential to modern cybersecurity and how he is building a security program designed for resilience, visibility, and scale with the help of Darktrace.

ダークトレースは、北朝鮮に関係すると思われる、韓国のユーザーを標的としたJSEベースのスピアフィッシングによる攻撃キャンペーンを検知しました。攻撃者は政府機関を装ったおとり文書を使ってVS Codeトンネルを展開し、信頼されるMicrosoftインフラ経由で隠れたリモートアクセスを可能にしました。この攻撃は、正規のツールを悪用して検知を免れ、永続的アクセスを維持しようとする攻撃の増加を裏付けています。

This blog breaks down how attackers rapidly weaponized the React2Shell vulnerability, with a particular focus on cloud‑native financial environments. Drawing on Darktrace’s honeypot research, it explores emerging threat actor tooling, exploitation timelines, and why behavioral‑anomaly‑led security is critical in today’s cloud landscape.

クラウドセキュリティはこれまで予防、ポスチャ管理、設定にかなりの重点が置かれてきました。しかし実際の攻撃はそこでは発生しません。 攻撃はランタイムにおいて、稼働中のワークロードやアイデンティティにわたって進行していきますが、そこでは可視性が限られており証拠が短時間で消滅します。 このブログではランタイムが保護すべき最もクリティカルなレイヤーである理由、動的なクラウドの挙動を攻撃者がどのように悪用しているか、なぜポスチャベースだけでは不十分かを紹介します。

Darktrace researchers observed threat actors exploiting reports of Venezuelan President Maduro’s arrest to deliver backdoor malware. Attackers often use ongoing world events make their malicious content appear more credible, increasingly the likelihood of a successful attack.

Medusa ransomware increasingly exploits remote monitoring and management (RMM) tools for persistence, lateral movement, and data exfiltration. This blog explores Medusa’s tactics, real-world detections, and how anomaly-based solutions with Autonomous Response can stop attacks.

AI is accelerating faster than governance can keep up, expanding attack surfaces and creating unseen risks. From data and models to AI agents and integrations, security starts by knowing what to protect. Discover how to identify AI-driven risks, so you can establish governance frameworks and controls that secure innovation without exposing the enterprise to new attack surfaces.
