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.

Darktrace detected a surge in Black Friday phishing campaigns exploiting brand impersonation, urgency-driven language, and malicious redirects. Attackers leveraged newly registered domains and social engineering to mimic Amazon, Louis Vuitton, and luxury watch retailers. Learn how layered evasion tactics bypassed security and how Darktrace / EMAIL neutralized these threats.

Black Friday continues to be a prime opportunity for threat actors, with early analysis from Darktrace showing a significant spike in attackers impersonating well-known brands, as well as the brands most frequently impersonated by scammers. Plus, check out our top tips to stay safe while filling your basket with deals.

TAG-150, a MaaS operator active since March 2025, uses CastleLoader and CastleRAT in multi-stage attacks. CastleLoader acts as a loader that retrieves and executes additional malware through deceptive domains and malicious GitHub repositories, while CastleRAT functions as a remote access trojan providing attackers with system control, command execution, and data theft capabilities. Darktrace detected and blocked early attack activity, leveraging Autonomous Response to prevent further compromise and protect enterprise networks.

Xillen Stealer v4/v5 introduces advanced features to evade AI detection, steal credentials, cryptocurrency, and sensitive data across browsers, password managers, and cloud environments. With polymorphic engines, container persistence, and behavioral mimicking, this Python-based malware highlights evolving threats and future AI integration in cybercrime campaigns.

本稿では、現代のOTが可視性だけに頼ることはできない理由、そしてゼロトラストアクセスコントロールとAI駆動のビヘイビア検知と組み合わせることにより、リアルタイムの監視、アカウンタビリティ、安全なリモートアクセスを、オペレーションを混乱させることなく実現する方法について、今後の展望も見据えて解説します。

Amazon Bedrockのような生成AIサービスは、アクセス、可視性、データ露出に関連した新たなリスクをもたらしつつあります。 本稿では、Darktrace / CLOUDがBedrockおよびSageMaker環境において、コンフィギュレーションに対する深い可視性、権限の分析、設定ミスの検知、挙動の異常の検知により、これらのインシデントを防ぐのにどう役立つかを解説します。

Earlier this year, Darktrace investigated the Vo1d malware campaign, tracing its activity from DGA-based DNS beaconing to major cloud infrastructure and ultimately to its C2 server communications.
