Introduction: AI cybersecurity predictions for 2025

Each year, Darktrace's AI and cybersecurity experts reflect on the events of the past 12 months and predict the trends we expect to shape the cybersecurity landscape in the year ahead. In 2024, we predicted that the global elections, fast-moving AI innovations, and increasingly cloud-based IT environments would be key factors shaping the cyber threat landscape.

Looking ahead to 2025, we expect the total addressable market of cybercrime to expand as attackers add more tactics to their toolkits. Threat actors will continue to take advantage of the volatile geopolitical environment and cybersecurity challenges will increasingly move to new frontiers like space. When it comes to AI, we anticipate the innovation in AI agents in 2024 to pave the way for the rise of multi-agent systems in 2025, creating new challenges and opportunities for cybersecurity professionals and attackers alike.

Here are ten trends to watch for in 2025:

1. The overall Total Addressable Market (TAM) of cybercrime gets bigger

Cybercrime is a global business, and an increasingly lucrative one, scaling through the adoption of AI and cybercrime-as-a-service. Annual revenue from cybercrime is already estimated to be over $8 trillion, which we’ve found is almost 5x greater than the revenue of the Magnificent Seven stocks. There are a few key factors driving this growth.

The ongoing growth of devices and systems means that existing malware families will continue to be successful. As of October 2024, it’s estimated that more than 5.52 billion people (~67%) have access to the internet and sources estimate 18.8 billion connected devices will be online by the end of 2024. The increasing adoption of AI is poised to drive even more interconnected systems as well as new data centers and infrastructure globally.

At the same time, more sophisticated capabilities are available for low-level attackers – we’ve already seen the trickle-down economic benefits of living off the land, edge infrastructure exploitation, and identity-focused exploitation. The availability of Ransomware-as-a-Service (RaaS) and Malware-as-a-Service (MaaS) make more advanced tactics the norm. The subscription income that these groups can generate enables more adversarial innovation, so attacks are getting faster and more effective with even bigger financial ramifications.

While there has also been an increasing trend in the last year of improved cross-border law enforcement, the efficacy of these efforts remains to be seen as cybercriminal gangs are also getting more resilient and professionalized. They are building better back-up systems and infrastructure as well as more multi-national networks and supply chains.

2. Security teams need to prepare for the rise of AI agents and multi-agent systems

Throughout 2024, we’ve seen major announcements about advancements in AI agents from the likes of OpenAI, Microsoft, Salesforce, and more. In 2025, we’ll see increasing innovation in and adoption of AI agents as well as the emergence of multi-agent systems (or “agent swarms”), where groups of autonomous agents work together to tackle complex tasks.

The rise of AI agents and multi-agent systems will introduce new challenges in cybersecurity, including new attack vectors and vulnerabilities. Security teams need to think about how to protect these systems to prevent data poisoning, prompt injection, or social engineering attacks.

One benefit of multi-agent systems is that agents can autonomously communicate, collaborate, and interact. However without clear and distinct boundaries and explicit permissions, this can also pose a major data privacy risk and avenue for manipulation. These issues cannot be addressed by traditional application testing alone. We must ensure these systems are secure by design, where robust protective mechanisms and data guardrails are built into the foundations.

3. Threat actors will be the earliest adopters of AI agents and multi-agent systems

We’ve already seen how quickly threat actors have been able to adopt generative AI for tasks like email phishing and reconnaissance. The next frontier for threat actors will be AI agents and multi-agent systems that are specialized in autonomous tasks like surveillance, initial access brokering, privilege escalation, vulnerability exploitation, data summarization for smart exfiltration, and more. Because they have no concern for safe, secure, accurate, and responsible use, adversaries will adopt these systems faster than cyber defenders.

We could also start to see use cases emerge for multi-agent systems in cyber defense – with potential for early use cases in incident response, application testing, and vulnerability discovery. On the whole, security teams will be slower to adopt these systems than adversaries because of the need to put in place proper security guardrails and build trust over time.

4. There is heightened supply chain risk for Large Language Models (LLMs)

Training LLMs requires a lot of data, and many experts have warned that world is running out of quality data for that training. As a result, there will be an increasing reliance on synthetic data, which can introduce new issues of accuracy and efficacy. Moreover, data supply chain risks will be an Achilles heel for organizations, with the potential interjection of vulnerabilities through the data and machine learning providers that they rely on. Poisoning one data set could have huge trickle-down impacts across many different systems. Data security will be paramount in 2025.

5. The race to identify software vulnerabilities intensifies

The time it takes for threat actors to exploit newly published CVEs is getting shorter, giving defenders an even smaller window to apply patches and remediations. A 2024 report from Cloudflare found that threat actors quickly weaponized proof of concept exploits in attacks as quickly as 22 minutes after the exploits were made public.

At the same time, 2024 also saw the first reports from researchers across academia and the tech industry using AI for vulnerability discovery in real-world code. With threat actors getting faster at exploiting vulnerabilities, defenders will need to use AI to identify vulnerabilities in their software stack and to help identify and prioritize remediations and patches.

6. Insider threat risks will force organizations to evolve zero trust strategies

In 2025, an increasingly volatile geopolitical situation and the intensity of the AI race will make insider threats an even bigger risk for businesses, forcing organizations to expand zero-trust strategies. The traditional zero-trust model provides protection from external threats to an organization’s network by requiring continuous verification of the devices and users attempting to access critical business systems, services, and information from multiple sources. However, as we have seen in the more recent Jack Teixeira case, malicious insiders can still do significant damage to an organization within their approved and authenticated boundary.

To circumvent the remaining security gaps in a zero-trust architecture and mitigate increasing risk of insider threats, organizations will need to integrate a behavioral understanding dimension to their zero-trust approaches. The zero-trust best practice of “never trust, always verify” needs to evolve to become “never trust, always verify, and continuously monitor.”

7. Identity remains an expensive problem for businesses

2024 saw some of the biggest and costliest attacks – all because the attacker had access to compromised credentials. Essentially, they had the key to the front door. Businesses still struggle with identity and access management (IAM), and it’s getting more complex now that we’re in the middle of a massive Software-as-a-Service (SaaS) migration driven by increasing rates of AI and cloud use across businesses.

This challenge is going to be exacerbated in 2025 by a few global and business factors. First, there is an increasing push for digital identities, such as the rollout of the EU Digital Identity Framework that is underway, which could introduce additional attack vectors. As they scale, businesses are turning more and more to centralized identity and access solutions with decentralized infrastructure and relying on SaaS and application-native security.

8. Increasing vulnerabilities at the edge

During the COVID-19 pandemic, many organizations had to stand-up remote access solutions quickly – in a matter of days or weeks – without the high level of due diligence that they require to be fully secured. In 2025, we expect to see continued fall-out as these quickly spun-up solutions start to present genuine vulnerability to businesses. We’ve already seen this start to play out in 2024 with the mass-exploitation of internet-edge devices like firewalls and VPN gateway products.

By July 2024, Darktrace’s threat research team observed that the most widely exploited edge infrastructure devices were those related to Ivanti Connect Secure, JetBrains TeamCity, FortiClient Enterprise Management Server, and Palo Alto Networks PAN-OS. Across the industry, we’ve already seen many zero days and vulnerabilities exploiting these internet-connected devices, which provide inroads into the network and store/cache credentials and passwords of other users that are highly valuable for threat actors.

9. Hacking Operational Technology (OT) gets easier

Hacking OT is notoriously complex – causing damage requires an intimate knowledge of the specific systems being targeted and historically was the reserve of nation states. But as OT has become more reliant and integrated with IT systems, attackers have stumbled on ways to cause disruption without having to rely on the sophisticated attack-craft normally associated with nation-state groups. That’s why some of the most disruptive attacks of the last year have come from hacktivist and financially-motivated criminal gangs – such as the hijacking of internet-exposed Programmable Logic Controllers (PLCs) by anti-Israel hacking groups and ransomware attacks resulting in the cancellation of hospital operations.  

In 2025, we expect to see an increase in cyber-physical disruption caused by threat groups motivated by political ideology or financial gain, bringing the OT threat landscape closer in complexity and scale to that of the IT landscape. The sectors most at risk are those with a strong reliance on IoT sensors, including healthcare, transportation, and manufacturing sectors.

10. Securing space infrastructure and systems becomes a critical imperative

The global space industry is growing at an incredibly fast pace, and 2025 is on track to be another record-breaking year for spaceflight with major missions and test flights planned by NASA, ESA, CNSA as well as the expected launch of the first commercial space station from Vast and programs from Blue Origin, Amazon and more. Research from Analysis Mason suggests that 38,000 additional satellites will be built and launched by 2033 and the global space industry revenue will reach $1.7 trillion by 2032. Space has also been identified as a focus area for the incoming US administration.

In 2025, we expect to see new levels of tension emerge as private and public infrastructure increasingly intersect in space, shining a light on the lack of agreed upon cyber norms and the increasing challenge of protecting complex and remote space systems against modern cyber threats.  Historically focused on securing earth-bound networks and environments, the space industry will face challenges as post-orbit threats rise, with satellites moving up the target list.

The EU’s NIS2 Directive now recognizes the space sector as an essential entity that is subject to its most strict cybersecurity requirements. Will other jurisdictions follow suit? We expect global debates about cyber vulnerabilities in space to come to the forefront as we become more reliant on space-based technology.

PHP脆弱性、ARTEX、そしてサイバー攻撃におけるAIの役割拡大

Default blog imageDefault blog image

BCVE-2026-109618およびCVE-2026-109619の公開により、PHPを運用している組織は緊急対応を余儀なくされました。どちらの脆弱性も許可のないリモートコード実行を可能にするものであり、対象はPHPが組み込まれ、サードパーティベンダーにアップデートを依存する製品およびアプライアンスも含まれていました[1]。

初期のガイダンスではインターネットに接続されたシステムにパッチを適用し、予期しないコマンド実行やWebroot変更、PHPサーバーからのアウトバウンド接続など、エクスプロイトの成功に関連した振る舞いを監視することに重点が置かれました。

Darktraceは監視中の環境においてスキャニングが広範に発生していることを観測し、これにはPHP脆弱性を標的としたアクティビティに関連すると報告されている数百の個別のIPアドレスが関係していました。スキャニングの量はエクスプロイトの成功を示す証拠の数を著しく上回るものでした。アナリストにとってはこの違いが重要です。スキャニングは露出したインフラへの関心を表すものです。侵害を確認するには、標的とされたシステム上でこれに続く振る舞い、たとえばコマンド実行、ファイル変更、予期しないアウトバウンド接続などの証拠が必要です。

PHPは例外的なケースではありません。その後、Imperva社が脆弱なNode.jsビルドに対するリモートコード実行を悪意あるBrotliデータを通じて実証し、圧縮HTTPレスポンスおよび設定済みリクエストパーサーを通じたコード実行を再現しました。同じ入力はパッチ適用済みのランタイムからは拒否されました。Imperva社はNode2ShellおよびPHP2Shellに対する研究結果を、脆弱性探索とエクスプロイト開発スピードの上昇と結びつけています。[2]

DarktraceはCVE-2026-109618あるいはCVE-2026-109619エクスプロイトの直接的証拠を観測していませんが、10月21日にゼロデイエクスプロイトのアクティビティと一致する過去6か月間で最大の脅威検知を観測し、これは過去のデータと比較して64%上昇を示すものでした。この上昇とPHP脆弱性との関連性は確認されていません。Darktraceの振る舞いベースのアプローチは、特定のエクスプロイトに対して記述されたルールだけに頼ることなく異常なアクティビティを検知するよう設計されています。同様の検知の増加はLog4j脆弱性の公表、およびその他の世界的に重大な脆弱性公表時にも観測されています。

AI支援による脆弱性探索

AIシステムが高い脆弱性探索能力を持つようになるなかで、PHPの脆弱性が発見されました[3]。OpenAIは2026年6月にDaybreakプログラムを発表し、GPT-5.5-CyberおよびCodex Securityをセキュリティ研究者やソフトウェア維持管理者とのパートナーシップと結びつけました。OpenAIはこれらのモデルがブラウザ、ネットワークインフラ、FreeBSDおよびLinuxカーネルの脆弱性の発見およびパッチ作成に適用されていると説明しています。ダークトレースは6月にOpenAI Daybreak Cyber Partner Programに参加し、OpenAIの提供するサイバー能力をDarktrace製品およびサービスにどのように統合できるかを研究しています [4][10]。

OpenAIは8月に、Codex Security Cloudが30,000以上のコードベースにおいて3000万件以上のコミットを分析したと報告しています。OpenAIによると、Cloudflare社はDaybreakを通じてアクセスするモデルを利用して、顧客の承認を受けたコードを調査し、その調査結果をリアルタイムのトラフィックやセキュリティシグナルと組み合わせて、影響を受けたルートがアクティブかどうか、または不審なトラフィックを受信しているかを評価し、顧客によるレビュー対象として緩和策やパッチを提案しているということです[5][6]。

迅速に発見することができても、影響を受けたソフトウェアを特定し、修正をテストし、是正措置を完了するという作業は、依然として防御者が行わなければなりません。PHPの事例は、特に脆弱なランタイムが他の製品に組み込まれている場合に、このギャップが問題となることを明確に示しています。

アタックサーフェスとしての企業AIエージェント

DarktraceSignal Labsは、攻撃者がすでに環境へのアクセス権を取得した後、信頼されたAIエージェントがどのように悪用される可能性があるかについても調査しました。ダークトレースの研究者は管理されたシミュレーション環境において、侵害後のシナリオとして、Claudeプラットフォームのメモリストア機能が悪用され、外部オペレーターと内部のClaude Codeエージェント間にライブC2チャネルを確立できることを実証しました。外部オペレーターは、このC2チャネルを介して、ネットワーク探索、認証情報へのアクセス、データの持ち出しといったタスクをエージェントに動的に割り当てることができました。エージェントのアクティビティの検知は、エージェントハーネスプロセスからのプロセス作成とネットワークトラフィックの相関付け、および予期された動作からの逸脱を特定するためのビヘイビア分析に基づいて行われました。ダークトレースはこのメモリストアを使ったC2テクニックを実際の攻撃で観測したとは主張していません[7]。

日本で観測されたAI支援による攻撃

日本で観測された証拠は、研究用環境を超えて、実際の脆弱性探索と攻撃にAIが使用されていることを示しています。10月21日、JPCERT/CCは最近の日本国内の組織に対する不正アクセスインシデントについての調査結果を発表しました。JPCERT/CCは攻撃者がAIを使って既知の脆弱性をスキャンしAPIを通じて攻撃を実行していることを確認したと報告しています。JPCERT/CCによると、攻撃インフラを調査した結果、Androidアプリケーションの分析、APIの探索、サーバーサイドリクエストフォージェリを含む脆弱性テストの痕跡が確認され、また、この攻撃インフラは日本国外のユーザー向けサービスも標的としていました[8]。

JPCERT/CCはこの公開資料の中ではARTEXを特定していません。ARTEXに対するアトリビューションは、Microsoft社によるStorm-0940の分析を含む、別の調査に基づいています。

攻撃オペレーションにおけるAI

Microsoft社は、ARTEXを限定的な人間の介入でアクティビティを自動化できる、オープンソースのマルチエージェント型ペネトレーションテストシステムと説明しています。Microsoft社は、2021年から活動している中国政府と連携した攻撃者と評価しているStorm-0940が、数百の組織に対してARTEXを使用したと報告し、ConnectWiseのサプライチェーン侵害がStorm-0940によるものであるとしました[9]。

Microsoft社は、ARTEXがスキャン、偵察、パスワードスプレー、OAuthアプリケーションの悪用を加速させていることを確認しました。ARTEXに駆動されたいくつかの攻撃オペレーションは、最初の標的設定から3時間未満で特権クラウドアクセスに到達しました。ConnectWiseの侵害後、Storm-0940は最大で毎分2,900回の頻度で、2,250を超えるテナントへの認証を試みました[9]。

ダークトレースの脅威調査チームは、後にこのキャンペーンとの関連が判明したインフラに関するアクティビティを、Darktraceテレメトリー内で発見しました。10月13日、Darktraceは、Microsoftが後にConnectWiseの顧客環境でサインインおよびMicrosoft Graphのアクティビティを実行していたと特定したアドレスの1つである144.172.64[.]128に関連する認証アクティビティの失敗を記録しました。Darktraceの分析では、約20分間に65回の認証失敗が確認されました。

図1:2026年10月13日、144.172.64[.]128が関与した認証失敗イベントを示すDarktrace Advanced Searchの結果(顧客を特定できる情報は削除済み)。

Darktraceのテレメトリーは、後にこのキャンペーンとの関連が確認されたインフラから、認証の失敗が繰り返し発生していたことを明らかにしています。これはARTEXの実行や侵害の成功を立証するものではありません。観測時点では、Microsoft社による後のアトリビューションについての情報はありませんでした。つまり、アナリストが把握していたのは振る舞いそのものでした。短時間に同一の送信元から認証に繰り返し失敗したということ、および関連するアイデンティティ、アプリケーション、ネットワークティビティについてのデータです。

Microsoft社は、10月10日から14日にかけて、8組織の327アカウントを対象とした、より広範なパスワードスプレー攻撃を報告しました。151,000件を超えるログオン失敗が記録され、なかでも11月10日には111,000件を超えていましたが、このキャンペーンによる認証成功、トークン発行、Graph呼び出し、ディレクトリ変更はいずれもありませんでした。また、Microsoftは、Storm-0940による標的化の大半が成功しなかったとも報告しています[9]。

攻撃者が認証を突破したケースでは、Microsoft社はサービスプリンシパルによるサインインに続いて、Graphおよびディレクトリ操作が行われたことを確認しました。アクティビティには、偵察、アプリケーション認証情報の変更、権限の変更を試みる行為が含まれていました。Microsoft社はサービスプリンシパルによるサインインとGraphアクティビティ、ディレクトリ変更およびリソースアクセスを相関づけることを推奨しています[9]。

アトリビューションの前に振る舞い

PHPとARTEXの事例は、異なる情報から始まっています。PHPの防御担当者は、どのソフトウェアに緊急の対策が必要かを把握していたものの、当初はエクスプロイトついての情報が限られていました。それでも、プロセスの実行、ファイルの変更、外部への通信は、侵害の証拠となったでしょう。

PHPとARTEXの観測結果は、量と影響範囲の違いも示しています。DarktraceはPHPの脆弱性公開時期に広範なスキャンを観測しました。一方ARTEX関連のインフラでは認証アクティビティが集中して発生していました。どちらの観察結果も、それ単独では侵害を実証するものではなく、いずれのケースにおいても、最初のやり取りに続く振る舞いを調べることが調査上の手がかりとなります。

DarktraceのARTEX関連の検知は、認証関連の振る舞いから始まりました。Microsoft社が攻撃インフラのアトリビューションを公表したのはその8日後でした。アトリビューションはコンテキストを提供するものではありましたが、環境内で最初に記録された事象を変更するものではありませんでした。

AIは今や攻撃サイクルの複数のポイントに存在しています。Daybreakは脆弱性の発見と修正にモデルを適用しています。Darktrace Signal Labsは信頼される企業内AIエージェントがどのように悪用されうるかを、管理された環境内で実証しました。JPCERT/CCは最近のインシデントにおけるAI支援による脆弱性探索およびAPI攻撃を確認しました。Microsoft社は実際の攻撃でStorm-0940がARTEXを使用していることを報告しました [4][7][8][9]。

Microsoft社の研究結果はまた、攻撃の規模と影響は別に評価しなければならないことも示しています。ARTEXを使った1つのキャンペーンは151,000回以上のログオン失敗を生成し、アクセスに至らなかったものの、他のキャンペーンでは3時間未満で特権クラウドアクセスに到達した例もありました。セキュリティチームは大量の試行アクティビティと、認証を突破し権限の変更やリソースアクセスへと進むものを区別しなければなりません。

これらのケースを評価するのに必要な証拠は、これまでに良く知られているものです。つまり認証記録、プロセス実行、アプリケーションやディレクトリの変更、ファイルアクティビティやネットワーク通信です。AIはこれらの振る舞いの発生頻度を増大させます。防御者はこのような状況下でもそれらのシーケンスと影響を判断しなければならないのです。

Beyond the Fridge: Exposed Industrial Control Systems

Default blog imageDefault blog image

Introduction

In October 2026, hundreds of supermarkets across France were reportedly affected by a cyberattack targeting their refrigeration systems. According to public reports, the attackers gained access to internet-connected controllers and modified their settings, forcing refrigeration units into high and extremely low temperatures and causing significant disruption. Total losses have been reported to reach several million euros.

The incident drew attention to the security of industrial refrigeration systems, particularly older devices with exposed management interfaces and known vulnerabilities.

The exact details of how the attackers gained access have not been confirmed, however it is speculated that the public-facing web server could be accessed with the username “admin” and password being the current date. Researchers from Claroty’s Team82 identified a vulnerability in Danfoss AK-SM 8xxA Series in 2025, “CVE-2025-41450", allowing for administrative access using a time-based “code-of-the-day" for authentication [1].

Default credentials, outdated firmware and publicly accessible administrative interfaces have been an issue for years. And yet these systems continue to appear in internet scans and require little sophistication to gain admin access. A simple search of internet-connected devices shows a range of exposed devices from Programmable Logic Controllers (PLCs) and remote gateways, to, yes, more fridges.

Darktrace malware researchers identified hundreds of IoT and OT devices publicly exposed on the internet, many of which are configured with no authentication, weak credentials, or default credentials. As shown in Figure 1, an exposed Copeland XWEB web interface, used to manage Dixell equipment, including refrigerators, can provide the ability to remotely control connected devices.

‍

Figure 1: Copeland XWEB interface used to control systems including refrigerators and air conditioning.

However, it’s not only fridges; web management interfaces for industrial controls are also publicly accessible, often protected only by weak credentials. Figure 2 shows an example of a publicly exposed WAGO interface. The WAGO management interface is a configuration and administration panel for controllers. Through it, a logged-in user can view device details and diagnostics, manage user accounts and passwords, update firmware, back up or restore the full configuration, set the clock, and manage SD card storage. While it typically doesn’t manage switch outputs or read live process values, someone with access could still disrupt operation by changing network or Modbus settings, loading bad firmware or configurations, or by resetting passwords and enabling insecure services.

‍

Figure 2: WAGO Management interface.

‍

The issue extends beyond management interfaces. During our research, we identified publicly accessible web interfaces belonging to PLCs, including Rockwell Automation Allen-Bradley devices. In each case, the risk arises from how the devices have been deployed and configured, not from a flaw in the vendors’ products.

‍

Figure 3: Web interface for Allen-Bradley CompactLogix controller.

‍

Figure 3 shows the web interface of an Allen-Bradley CompactLogix controller. Unlike the previous examples, this interface provides a view into the controller's operation, including running tasks, network connections, memory usage and diagnostic information. Rockwell Automation's CompactLogix controllers are commonly used to automate industrial processes, from manufacturing and packaging lines to water treatment and material handling systems. Depending on their configuration, these controllers can operate motors, pumps, valves and other physical equipment.

Although in this example the interface shown does not provide direct control over the PLC's logic, it exposes information about the model, firmware, network layout, and connections, which is useful reconnaissance for a bigger attack.

The concern is not necessarily that every exposed interface allows an attacker to immediately manipulate industrial processes. However, these devices are accessible from the public internet in the first place, providing information about systems that may be responsible for controlling physical equipment.

The attacks on refrigeration systems in France highlight the consequences of poorly secured industrial devices. As demonstrated throughout this research, publicly accessible management interfaces are not limited to refrigeration controllers but extend to PLCs and other systems used to manage industrial equipment.

Finding these devices requires little effort. Internet scanners make it possible to identify publicly exposed interfaces quickly, and in some cases these interfaces rely on publicly documented default credentials or have no authentication at all. As attackers increasingly use AI tools, such attacks may be identified and carried out faster and at a greater scale.

The consequences of this access depend on the device and the functionality exposed. While some interfaces provide little more than diagnostic information, others allow users to modify configurations, disrupt communications, or change settings that affect physical equipment. In industrial environments, this can result in operational downtime, damaged equipment and financial losses.

Weak passwords, default credentials and exposed administrative interfaces are not new security issues. Yet their continued presence on internet-connected industrial systems demonstrates how easily preventable weaknesses can leave physical operations vulnerable to attack.

Exposed devices often come from third-party suppliers and contractors, who frequently install refrigeration controllers, gateways and PLCs without the organization ever being aware they are connected to the internet. Asset visibility remains an important foundation, but organizations should assume that some unknown assets and services will exist. Effective security therefore also depends on continuous monitoring, anomaly detection, network segmentation and rapid response, so that risky exposure and unusual activity can be identified and addressed before it becomes disruptive.
