Eメールセキュリティの統合により、各サイロの総和を超える体制を構築







サイバー攻撃の94%は受信トレイから侵入してきますが、その行き先はほとんどEメールではありません。攻撃の行き先は、クラウドアプリやインフラ、エンドポイント、ネットワークなど、他の領域に及ぶことが多いのです。そのため、セキュリティチームは、Eメールセキュリティの強固な基盤を確立する必要がありますが、それらのソリューションがより広範なセキュリティ体制にどのように適合するかも考慮する必要があります。
Darktrace/Email™は、それ自体で、攻撃が従業員の受信トレイに到達する前に阻止し、セキュリティチームと従業員自身の双方を考慮します。しかし、その価値はメールセキュリティにとどまらず、Darktrace 製品や外部ツールなど、より広範なセキュリティエコシステムと統合する能力によって向上しています。
Darktraceは、御社と御社の組織全体に対する理解を、御社がデータを持っている領域であればどこでも適用することができます。サイバーセキュリティに対するこの統一的なアプローチは、Cyber AI Loop™の基礎を築くもので、Darktrace の全製品がAI出力を相互にフィードし、自律的かつ継続的にセキュリティ体制全体を強化します。また、AIはデータを取り込み、共有することで、組織が導入している他のセキュリティソリューションも充実させます。このような統合の度合いにより、セキュリティスタックは、その部分の総和を超えるものになるのです。

Eメールの枠を超えた統合で検知・対処能力を強化する
Eメールのセキュリティをデジタル資産の他の領域と統合することで、必要なリソースを削減しながら、防御を強化することができます。より多くのデータにより、セキュリティチームはセキュリティスタックと攻撃がどのようにシステムを通過していくかをより深く理解することができます。
従来のセキュリティソリューションでは、さまざまなツールからの入力を手動で集約するか、ネイティブな統合機能を持たないSIEMを使用してデータを照合することでこれを実現していました。これに対し、Darktrace'の統合は、製品間でリアルタイムにインテリジェントな通信を行い、セキュリティチームに情報を提供します。
例えば、ネットワークアクティビティのコンテキストは、より全体的なEメールセキュリティを提供することができます。ユーザーが訪問するウェブサイトとEメールを送る相手には強い相関関係があります。つまり、ウェブトラフィックのような情報はEメールの脅威に関する洞察を提供し、その逆もまた然りです。
ある組織が、見知らぬ新しい送信者からEメールを受け取り、それが偶然にも誰も訪れたことのないドメインから送信されていた場合、その追加されたコンテキストは、実行するアクションの攻撃レベルに影響を与える可能性があります。エンドポイントセキュリティとの統合により、このような情報に基づく意思決定がリモート環境でも可能になります。これらの例は、Darktrace/Network™とDarktrace/Endpoint™をEメールカバレッジと組み合わせることで、特許も取得済みの独自の能力を発揮します。

Eメールのアクティビティは、さらに直接的な方法でクラウド/SaaSアプリケーションのアカウントアクティビティと結びついています。アカウント乗っ取りの場合、Microsoft 365への不審なログインに続いて、新しい受信トレイのルールが作成されるなど、非常に珍しいEメールアクティビティが発生すると、さらに不審に思われます。多くのEメールセキュリティソリューションは受信トレイだけに焦点を当てていますが、これらの領域を単一のスコープで見ることは、インシデントの完全なタイムラインを理解したいセキュリティチームにとって重要です。
このため、Darktrace は、各ユーザーとその行動に関する 360 度のビューを作成します。この包括的なビューは、ネイティブのセキュリティ監視ツールを超えるもので、セキュリティチームは、データ流出、人的ミス、Eメールの誤送信、不適切なリンク共有、異常なログ活動などの事例を即座に特定することができます。
ある実例では、Darktrace/EmailとDarktrace/Apps™のおかげで、セキュリティチームはEメールとSaaSの両方の視点から攻撃を見て、全体像を素早く理解することができました。
Darktrace は、この統合されたセキュリティスタックから大きな価値を得ています。「この製品群のおかげで、エコシステム全体を100%可視化できるようになり、素晴らしいことです。そのためには、多くの製品を使用する必要がありますが、Darktrace の製品では、そのすべてが1つにまとまっています」と、ある大手信用組合の企業セキュリティおよび不正管理担当バイスプレジデントはコメントしています。
サイバー業界では、サイロ化したソリューションが大きな痛手となっています。ほとんどの企業では、セキュリティスタックに複数のツールを多重的に導入しています。これらのツール間のコミュニケーションがほとんどない場合、セキュリティチームは増大する作業負荷に対処しなければならず、価値を見失うことになります。毎日すべてのソリューションを監視するだけでなく、複数の異なるダッシュボードを操作し、言語や用語を翻訳し、データを手動で相関させる方法を学ばなければなりません。このようなプロセスは、特に複雑化し、攻撃のペースが速くなる脅威ランドスケープにおいて、チームにとってセキュリティの維持をより困難なものにしています。
Darktrace/Email は、セキュリティチームが既に使用している他のツールとの間で情報を送受信することで、それらがDarktraceの製品スタックの一部であるかどうかにかかわらず、ワークフローを最適化し、セキュリティチームがより大規模で戦略的なプロジェクトにリソースを再配分できるようにします。
Eメールセキュリティとサイバーリスクマネジメントツールを横断するコラボレーション
Eメール保護とサイバーリスクマネジメントツールを同期させることで、さらにリスクを低減し、セキュリティを強固にすることができます。
クライアントのブランドに関連するドメイン名からEメールを受信した場合、攻撃対象範囲に含めるべきか、悪意のあるドメインの応答をトリガーすべきか、アタックサーフェス管理ツールが自動的に分析することができます。
一方、アタックサーフェス管理ツールが、疑わしいドメイン、なりすましサイト、タイポスクワッターなどの悪意のある資産を特定した場合、Eメールセキュリティの意思決定に役立てることができます。ツール間の統合により、これらの悪意のある資産は自動的にインバウンドメールの感度を高めた監視ドメインとなります。
このような統合的なリスク低減は、社内でも起こり得ます。セキュリティチームが社内の視点からサイバーリスクを見ると、社内のデジタル資産の中から攻撃経路や価値の高い標的を特定することができます。この理解を活用することで、Darktrace はどの従業員が潜在的な攻撃経路の重要な構成要素であるかを判断することができます。そして、実際のコミュニケーションパターンやカレンダーのデータなどを使ってフィッシングシミュレーションを行い、その結果をAIが検証することができます。これらのテストによって得られた知見は、Darktrace/Emailにフィードバックされ、感度を高めるなどして環境を強化することができます。
これは、Darktrace/EmailとDarktrace PREVENT™ を組み合わせることの利点を示しています。 Cyber AI Loopの一部として、Eメールセキュリティとサイバーリスクマネジメントの間のこれらの接続は、セキュリティチームが理解し、行動することが容易になっています。あるお客様は、この統合によってセキュリティチームのワークフローが改善されたと述べています。
ある建設会社の最高情報責任者(CIO)は、「Darktrace を使えば使うほど、より良い相関関係を構築することができます。だからこそ、私たちは現在Darktrace を使っているのです。私たちはDarktrace の全体的なフットプリントを持ち、より多くのモジュールが私たちのために稼働し、別々に、あるいは孤立して相関を行う必要がないため、私たちに大きな利益をもたらしています」と述べています。
外部セキュリティソリューションとの親和性をサポート
Darktrace/Emailはまた外部ツールとも連携しています。Microsoft 365やGoogle WorkspaceなどのEメールプロバイダとの成熟した統合に加え、Darktrace/Emailはオープンアーキテクチャを採用しているため、非常に柔軟性があります。API駆動でsyslogとの互換性があるため、あらゆるセキュリティツールと統合し、SIEMやSOARにフィードすることが可能です。
この無限の統合能力により、Darktrace はより多くのデータにアクセスすることで、より正確に脅威を検知し対処することができます。また、すべての関連情報を1枚の画面に収めることで、セキュリティチームの意味付けまでの時間を短縮することができます。
Darktrace/Emailは、Darktrace モバイルアプリの一部でもあり、セキュリティチームは、外出先でもいつでも通知、レポート、改善アクションを確認することができます。このようにDarktrace は、より大きなセキュリティ態勢に適合するだけでなく、従業員の日々のワークフローにも適合しています。
最後に、Darktrace/Emailは、データエクスポートをサポートしています。これにより、Eメール環境内で収集したデータを翻訳して共有することができ、セキュリティチームは、Darktrace/Emailで生成された重要な手掛かりを組織内の誰にでも伝えることができるようになります。Microsoft Excelやその他のデータ分析ツールに直接エクスポートすることができます。これは、IT、コンプライアンス、財務などの他部門と連携するセキュリティチームにとって、特に有用です。
統合はDarktrace パートナーシップの価値を高める
Darktrace/Emailはそれ自体で強力なツールですが、その価値の大きな源泉は、Darktrace の他のツール、人、およびプロセスとの互換性にあります。
複数のDarktrace 製品を導入することで、強固なセキュリティエコシステムが構築され、サイロを破壊してワークフローを改善しながら検知を強化するため、セキュリティチームはより高度で戦略的な業務に取り組むことができるようになります。外部ツールとの統合により、Darktrace は自身の価値を高めるだけでなく、チームがすでに持っている他のセキュリティソリューションの投資対効果を最大化することができます。

PurpleFox in a Henhouse: How Darktrace Hunted Down a Persistent and Dynamic Rootkit



Versatile Malware: PurpleFox
As organizations and security teams across the world move to bolster their digital defenses against cyber threats, threats actors, in turn, are forced to adopt more sophisticated tactics, techniques and procedures (TTPs) to circumvent them. Rather than being static and predictable, malware strains are becoming increasingly versatile and therefore elusive to traditional security tools.
One such example is PurpleFox. First observed in 2018, PurpleFox is a combined fileless rootkit and backdoor trojan known to target Windows machines. PurpleFox is known for consistently adapting its functionalities over time, utilizing different infection vectors including known vulnerabilities (CVEs), fake Telegram installers, and phishing. It is also leveraged by other campaigns to deliver ransomware tools, spyware, and cryptocurrency mining malware. It is also widely known for using Microsoft Software Installer (MSI) files masquerading as other file types.
The Evolution of PurpleFox
The Original Strain
First reported in March 2018, PurpleFox was identified to be a trojan that drops itself onto Windows machines using an MSI installation package that alters registry values to replace a legitimate Windows system file [1]. The initial stage of infection relied on the third-party toolkit RIG Exploit Kit (EK). RIG EK is hosted on compromised or malicious websites and is dropped onto the unsuspecting system when they visit browse that site. The built-in Windows installer (MSIEXEC) is leveraged to run the installation package retrieved from the website. This, in turn, drops two files into the Windows directory – namely a malicious dynamic-link library (DLL) that acts as a loader, and the payload of the malware. After infection, PurpleFox is often used to retrieve and deploy other types of malware.
Subsequent Variants
Since its initial discovery, PurpleFox has also been observed leveraging PowerShell to enable fileless infection and additional privilege escalation vulnerabilities to increase the likelihood of successful infection [2]. The PowerShell script had also been reported to be masquerading as a .jpg image file. PowerSploit modules are utilized to gain elevated privileges if the current user lacks administrator privileges. Once obtained, the script proceeds to retrieve and execute a malicious MSI package, also masquerading as an image file. As of 2020, PurpleFox no longer relied on the RIG EK for its delivery phase, instead spreading via the exploitation of the SMB protocol [3]. The malware would leverage the compromised systems as hosts for the PurpleFox payloads to facilitate its spread to other systems. This mode of infection can occur without any user action, akin to a worm.
The current iteration of PurpleFox reportedly uses brute-forcing of vulnerable services, such as SMB, to facilitate its spread over the network and escalate privileges. By scanning internet-facing Windows computers, PurpleFox exploits weak passwords for Windows user accounts through SMB, including administrative credentials to facilitate further privilege escalation.
Darktrace detection of PurpleFox
In July 2023, Darktrace observed an example of a PurpleFox infection on the network of a customer in the healthcare sector. This observation was a slightly different method of downloading the PurpleFox payload. An affected device was observed initiating a series of service control requests using DCE-RPC, instructing the device to make connections to a host of servers to download a malicious .PNG file, later confirmed to be the PurpleFox rootkit. The device was then observed carrying out worm-like activity to other external internet-facing servers, as well as scanning related subnets.
Darktrace DETECT™ was able to successfully identify and track this compromise across the cyber kill chain and ensure the customer was able to take swift remedial action to prevent the attack from escalating further.
While the customer in question did have Darktrace RESPOND™, it was configured in human confirmation mode, meaning any mitigative actions had to be manually applied by the customer’s security team. If RESPOND had been enabled in autonomous response mode at the time of the attack, it would have been able to take swift action against the compromise to contain it at the earliest instance.
攻撃の概要

Initial Scanning over SMB
On July 14, 2023, Darktrace detected the affected device scanning other internal devices on the customer’s network via port 445. The numerous connections were consistent with the aforementioned worm-like activity that has been reported from PurpleFox behavior as it appears to be targeting SMB services looking for open or vulnerable channels to exploit.
This initial scanning activity was detected by Darktrace DETECT, specifically through the model breach ‘Device / Suspicious SMB Scanning Activity’. Darktrace’s Cyber AI Analyst™ then launched an autonomous investigation into these internal connections and tied them into one larger-scale network reconnaissance incident, rather than a series of isolated connections.

As Darktrace RESPOND was configured in human confirmation mode, it was unable to autonomously block these internal connections. However, it did suggest blocking connections on port 445, which could have been manually applied by the customer’s security team.

特権昇格
The device successfully logged in via NTLM with the credential, ‘administrator’. Darktrace recognized that the endpoint was external to the customer’s environment, indicating that the affected device was now being used to propagate the malware to other networks. Considering the lack of observed brute-force activity up to this point, the credentials for ‘administrator’ had likely been compromised prior to Darktrace’s deployment on the network, or outside of Darktrace’s purview via a phishing attack.
Exploitation
Darktrace then detected a series of service control requests over DCE-RPC using the credential ‘admin’ to make SVCCTL Create Service W Requests. A script was then observed where the controlled device is instructed to launch mshta.exe, a Windows-native binary designed to execute Microsoft HTML Application (HTA) files. This enables the execution of arbitrary script code, VBScript in this case.


There are a few MSIEXEC flags to note:
- /i : installs or configures a product
- /Q : sets the user interface level. In this case, it is set to ‘No UI’, which is used for “quiet” execution, so no user interaction is required
Evidently, this was an attempt to evade detection by endpoint users as it is surreptitiously installed onto the system. This corresponds to the download of the rootkit that has previously been associated with PurpleFox. At this stage, the infected device continues to be leveraged as an attack device and scans SMB services over external endpoints. The device also appeared to attempt brute-forcing over NTLM using the same ‘administrator’ credential to these endpoints. This activity was identified by Darktrace DETECT which, if enabled in autonomous response mode would have instantly blocked similar outbound connections, thus preventing the spread of PurpleFox.

Installation
On August 9, Darktrace observed the device making initial attempts to download a malicious .PNG file. This was a notable change in tactics from previously reported PurpleFox campaigns which had been observed utilizing .MOE files for their payloads [3]. The .MOE payloads are binary files that are more easily detected and blocked by traditional signatured-based security measures as they are not associated with known software. The ubiquity of .PNG files, especially on the web, make identifying and blacklisting the files significantly more difficult.
The first connection was made with the URI ‘/test.png’. It was noted that the HTTP method here was HEAD, a method similar to GET requests except the server must not return a message-body in the response.
The metainformation contained in the HTTP headers in response to a HEAD request should be identical to the information sent in response to a GET request. This method is often used to test hypertext links for validity and recent modification. This is likely a way of checking if the server hosting the payload is still active. Avoiding connections that could possibly be detected by antivirus solutions can help keep this activity under-the-radar.


The server responds with a status code of 200 before the download begins. The HEAD request could be part of the attacker’s verification that the server is still running, and that the payload is available for download. The ‘/test.png’ HEAD request was sent twice, likely for double confirmation to begin the file transfer.

Subsequent analysis using a Packet Capture (PCAP) tool revealed that this connection used the Windows Installer user agent that has previously been associated with PurpleFox. The device then began to download a payload that was masquerading as a Microsoft Word document. The device was thus able to download the payload twice, from two separate endpoints.
By masquerading as a Microsoft Word file, the threat actor was likely attempting to evade the detection of the endpoint user and traditional security tools by passing off as an innocuous text document. Likewise, using a Windows Installer user agent would enable threat actors to bypass antivirus measures and disguise the malicious installation as legitimate download activity.
Darktrace DETECT identified that these were masqueraded file downloads by correctly identifying the mismatch between the file extension and the true file type. Subsequently, AI Analyst was able to correctly identify the file type and deduced that this download was indicative of the device having been compromised.
In this case, the device attempted to download the payload from several different endpoints, many of which had low antivirus detection rates or open-source intelligence (OSINT) flags, highlighting the need to move beyond traditional signature-base detections.



If Darktrace RESPOND was enabled in autonomous response mode at the time of the attack it would have acted by blocking connections to these suspicious endpoints, thus preventing the download of malicious files. However, as RESPOND was in human confirmation mode, RESPOND actions required manual application by the customer’s security team which unfortunately did not happen, as such the device was able to download the payloads.
結論
The PurpleFox malware is a particularly dynamic strain known to continually evolve over time, utilizing a blend of old and new approaches to achieve its goals which is likely to muddy expectations on its behavior. By frequently employing new methods of attack, malicious actors are able to bypass traditional security tools that rely on signature-based detections and static lists of indictors of compromise (IoCs), necessitating a more sophisticated approach to threat detection.
Darktrace DETECT’s Self-Learning AI enables it to confront adaptable and elusive threats like PurpleFox. By learning and understanding customer networks, it is able to discern normal network behavior and patterns of life, distinguishing expected activity from potential deviations. This anomaly-based approach to threat detection allows Darktrace to detect cyber threats as soon as they emerge.
By combining DETECT with the autonomous response capabilities of RESPOND, Darktrace customers are able to effectively safeguard their digital environments and ensure that emerging threats can be identified and shut down at the earliest stage of the kill chain, regardless of the tactics employed by would-be attackers.

OT
$70 Million in Cyber Security Funding for Electric Cooperatives & Utilities



What is the Bipartisan Infrastructure Deal?
The Bipartisan Infrastructure Law passed by congress in 2021 aimed to upgrade power and infrastructure to deliver clean, reliable energy across the US to achieve zero-emissions. To date, the largest investment in clean energy, the deal will fund new programs to support the development and deployment of clean energy technology.
Why is it relevant to electric municipalities?
Section 40124 of the Bipartisan Infrastructure Law allocates $250 million over a 5-year period to create the Rural and Municipal Utility Cybersecurity (RMUC) Program to help electric cooperative, municipal, and small investor-owned utilities protect against, detect, respond to, and recover from cybersecurity threats.1 This act illuminates the value behind a full life-cycle approach to cyber security. Thus, finding a cyber security solution that can provide all aspects of security in one integrated platform would enhance the overall security posture and ease many of the challenges that arise with adopting multiple point solutions.
On November 16, 2023 the Office of Cybersecurity, Energy Security, and Emergency Response (CESER) released the Advanced Cybersecurity Technology (ACT) for electric utilities offering a $70 million funding opportunity that aims to enhance the cybersecurity posture of electric cooperative, municipal, and small investor-owned utilities.
Funding Details
10 projects will be funded with application submissions due November 29, 2023, 5:00 pm ET with $200,000 each in cash prizes in the following areas:
- Direct support for eligible utilities to make investments in cybersecurity technologies, tools, training, and improvements in utility processes and procedures;
- Funding to strengthen the peer-to-peer and not-for-profit cybersecurity technical assistance ecosystem currently serving eligible electric utilities; and
- Increasing access to cybersecurity technical assistance and training for eligible utilities with limited cybersecurity resources. 2
To submit for this award visit: https://www.herox.com/ACT1Prize
How can electric municipalities utilize the funding?
While the adoption of hybrid working patterns increase cloud and SaaS usage, the number of industrial IoT devices also continues to rise. The result is decrease in visibility for security teams and new entry points for attackers. Particularly for energy and utility organizations.
Electric cooperatives seeking to enhance their cyber security posture can aim to invest in cyber security tools that provide the following:
Compliance support: Consider finding an OT security solution that maps out how its solutions and features help your organization comply with relevant compliance mandates such as NIST, ISA, FERC, TSA, HIPAA, CIS Controls, and more.
Anomaly based detection: Siloed security solutions also fail to detect attacks that span
the entire organization. Anomaly-based detection enhances an organization’s cyber security posture by proactively defending against potential attacks and maintaining a comprehensive view of their attack surface.
Integration capabilities: Implementation of several point solutions that complete individual tasks runs the risk of increasing workloads for operators and creates additional challenges with compliance, budgeting, and technical support. Look for cyber security tools that integrate with your existing technologies.
Passive and active asset tracking: Active Identification offers accurate enumeration, real time updates, vulnerability assessment, asset validation while Passive Identification eliminates the risk of operational disruption, minimizes risk, does not generate additional network traffic. It would be ideal to find a security solution that can do both.
Can secure both IT and OT in unison: Given that most OT cyber-attacks actually start in IT networks before pivoting into OT, a mature security posture for critical infrastructure would include a single solution for both IT and OT. Separate solutions for IT and OT present challenges when defending network boundaries and detecting incidents when an attacker pivots from IT to OT. These independent solutions also significantly increase operator workload and materially diminish risk mitigation efforts.
Darktrace/OT for Electric Cooperatives and Utilities
For smaller teams with just one or two dedicated employees, Darktrace’s Cyber AI Analyst and Investigation features allow end users to spend less time in the platform as it compiles critical incidents into comprehensive actionable event reports. AI Analyst brings all the information into a centralized view with incident reporting in natural language summaries and can be generated for compliance reports specific to regulatory requirements.
For larger teams, Darktrace alerts can be forwarded to 3rd party platforms such as a SIEM, where security team decision making is augmented. Additionally, executive reports and autonomous response reduce the alert fatigue generally associated with legacy tools. Most importantly, Darktrace’s unique understanding of normal allows security teams to detect zero-days and signatureless attacks regardless of the size of the organization and how alerts are consumed.
Key Benefits of Darktrace/OT
- Anomaly-based detection and real-time response
- Secures IT, OT, and IoT in unison
- Active and Passive Asset Identification
- Automated security reporting
- Attack surface management and vulnerability assessment
- Covers all levels of the Purdue Model
