Last summer’s wave of ransomware attacks compromised port terminals and disrupted global shipping. Since then, cyber security has quickly risen to the top of the agenda for the maritime sector. Earlier this year, another port was hit with ransomware, and then, last week, the ports of Barcelona and San Diego revealed that they had been the victims of further ransomware attacks.
Whilst the 2017 attacks were globally devastating, there was no evidence that they deliberately targeted particular sectors; port terminals were merely caught in the indiscriminate wave of attacks. However, the widespread disruption these attacks caused across industry – from shipping to manufacturing – drew attention to the risk of IT cyber-attacks propagating into the industrial sector’s critical control systems. Operational Technology within industrial environments had previously been kept relatively separate from IT systems, and, consequently, relatively immune from cyber-attack. These attacks showed that the recent trend in integrating and unifying IT and OT systems had now exposed these systems to such indiscriminate attacks.
The increasing convergence of IT and OT systems shows no signs of slowing, however. Hyper-connected ‘smart’ ports are bringing efficiency and precision while cutting costs. Yet, the intertwining of the physical and digital across ports remains a significant challenge for the cyber security teams tasked with their defense. Without rushing to conclusions, it is perhaps no surprise that the Port of Barcelona is in the process of a “Digital Port project,” launched last year to promote the digitization of the port environment.
Although specifics have not yet been revealed, the recent attacks in Barcelona and San Diego appear to be targeted. Perhaps the inadvertent success of last year’s ransomware campaign inspired attackers to pursue the maritime sector specifically. Disruptions to Operational Technology can be highly detrimental to the maritime sector – these systems oversee critical port and ship systems. Any compromise could inflict reputational harm, significant financial losses, and physical damage. That we would see ransomware attacks specifically targeting ports was foreseeable. Many in the industry have been expecting and preparing for such an eventuality over the last 12 months. Now that attackers are actively targeting them, the protection of OT systems has become critical.
Darktrace has deployed AI to a number of companies in the maritime sector to specifically mitigate and defend Operational Technology. These systems are highly customized and bespoke, and therefore unsuitable for the use of off-the-shelf IT solutions. Darktrace’s cyber AI is able to automatically tailor to OT environments and learn a unique sense of ‘self’, regardless of vendor or technology platform.
Our AI is actively defending ports across the world – such as Harwich Haven Authority and Belfast Harbour – and protecting them against both targeted and indiscriminate attacks on their OT and IT systems. Defending these environments requires the ability to protect all technology systems, from the oldest PLCs and SCADA systems, to the newest IoT devices. Whether in the cloud, on a vessel, or on the mainland, Darktrace is able to passively defend your systems and identify cyber-threats in real time, without any impact or disruption.

“I wonder if running that tool influenced the connectivity in some way.”
“I might need to target down or reboot, but first, I'll investigate the network using ARP. I wonder if ARP is responding properly. If I see "ip neigh stale," that could indicate a problem. I think arping might help in this situation, but I’ll need to keep an eye on how the network is behaving. It's all about figuring out where the issue lies!”
図10：エージェントの異常なLDAPアクティビティに対してトリガーされたこのLinuxサーバーに対するモデル検知は、Cyber AI Analystによって自律的に調査され、その調査結果にはエージェントの異常なSMBセッションアクティビティに関する内容が含まれ、Cyber AIAnalystインシデントに記録されました。
DarktraceのCyber AI Analystは、エージェントのアクティビティによってトリガーされたモデル検知を自律的に調査し、その調査結果を1つの重要なインシデントレポートにまとめました。インシデント報告書の内容は、エージェントによるネットワークスキャンから始まりコーディング演習内容のSMBベースの上書きで終わる、エージェントの行動の各段階を詳しくカバーしています。
図20：Cyber AI Analystは、モデル検知に対する自律的な調査を通じて得られた所見をつなぎ合わせ、エージェントの進行状況のタイムラインを作成し、アクティビティを視覚的に表したグラフとともに提供しました。
Cyber Verification Program下のAnthropic Opus 4.6モデルなど、他のフロンティアモデルを使用したエージェントも、Darktraceのシミュレートされた環境で同じ設定とタスクを使ってテストされました。反復の度に、エージェントは演習の内容または採点プログラムを変更して不正を行おうとしました。基盤となるモデルに関係なく、エージェントは自分が置かれた環境を侵害することで、100％のスコアを達成する方法を見つけることに成功していました。これらのエージェントによるハッキングは、アクティビティの内容こそ違っていましたが、すべてその環境のベースラインの振る舞いから大きく逸脱した動作を引き起こしていました。これらの逸脱はDarktraceプラットフォームに十分な検知の機会を提供し、エージェントの逃げ場はありませんでした。
エージェンティックハーネスは会話履歴をローカルに保存しますが、ダークトレースの研究者たちは、保存されたAIの応答が本当にモデルによって生成されたものであるかどうかの検証が行われていないことを発見しました。また、この設計上の選択がAnthropic Claude Code、AWS Kiro-CLI、OpenAI Codex、およびオープンソースのPiにわたって共通していることを確認しました。
会話履歴は多くの場合クライアント側に保存されます。例えば、Anthropic Claude Code、OpenAI Codex、AWS Kiro-CLI、Piなどでもそうです。そのため、ユーザーはセッションを自由に再開でき、一部の製品にはその履歴を操作する機能が組み込まれています。たとえば、会話の中の特定の時点に戻り、送信したメッセージを編集して、会話を別の軌道へ進めていくことができます。きわめて重要な点として、私たちが調査したすべてのケースにおいて、保存されているAIの応答が対応するモデルから生成されたものであり改ざんされていないことの検証は行われていませんでした。
