As Black Friday and Cyber Monday approach, retailers are gearing up for what is predicted to be a holiday season worth around $214 billion in e-commerce sales. They are not alone in making special preparations: in the cyber-criminal underworld, hackers are looking to use the influx of limited-time offers to incite a sense of urgency and lure victims with phishing emails disguised as Black Friday deals.

And as the holiday season draws nearer, another familiar attack vector threatens to dampen the festive cheer. With security teams enjoying well-earned breaks, upcoming public holidays present the perfect opportunity for ransomware attackers to strike. We covered this topic in detail earlier this year, and over the Fourth of July bank holiday weekend, the ‘largest ever ransomware attack’ wreaked havoc across the world, affecting up to 1,500 organizations.

With sophisticated festive phishing and the recent well-documented surge in ransomware, the stage is set for this holiday season to be one filled with cyber disruption. Security teams need all the help they can get to face this year’s ‘hacking season’ with best-in-class technology that keeps a watchful eye over the digital enterprise 365 days a year.

Attacks know no boundaries

Most of us tend to use personal email addresses for our holiday shopping, but in an era of remote and hybrid working, this can easily have knock-on effects, granting attackers a backdoor into the corporate sphere. The pandemic has seen a greater number of organizations focused on enabling remote and flexible working in whatever ways possible to ‘get the job done.’

BYOD (‘Bring Your Own Device’) has seen a surge in popularity to enable flexible working, increase efficiency, reduce costs, and give employees the opportunity to use IT they feel comfortable with.

From a digital perspective, this has led to increasing convergence of our personal and professional lives. Phishing emails that target personal email accounts – often using more relaxed email security measures – therefore put organizations at risk. Malicious executable files may grant an attacker access to the device, and from here they can pivot into corporate activity, and infiltrate an organization through a single, careless employee.

It’s not just BYOD users who are at risk. Despite the warnings, password reuse continues to be widespread, meaning a successful credential-grab on a personal account can potentially give attackers the keys to a wide range of corporate accounts, whether it’s Microsoft 365 or any number of other internal systems.

A longer holiday calendar expands the attack ‘calendar’ surface

This year, disruptions in the global supply chain are already causing problems for shipping and delays. In response, retailers like Best Buy are offering special deals well ahead of Black Friday with the price promise that they’ll refund the difference should the price drop further on the day itself.

This extends the time period in which these offers are promoted, and thereby the attack ‘calendar’ surface, gifting attackers an extra few weeks through which to launch seasonal scams.

And we know from experience that attackers can get creative, not only with emails disguised as Black Friday offers and promotions, but also spoofing attacks posing as delivery firms, or other third-party logistics suppliers. They will try anything which might induce a click on a link or attachment.

They see you when you’re sleeping: Hackers won’t take holiday

During public holidays, IT and security teams drastically reduce in size. Attackers know this, and it no longer comes as a surprise when some of the largest cyber-attacks of the year are detonated during this time. Adopting reliable autonomous security, and in particular autonomous response, has never been more important in ensuring organizations stay protected.

With opportunistic hackers looking to spoil the holiday season for some quick returns, we cannot rely on human teams alone. Human beings are fallible: they get tired, they need breaks, and they get complacent. One simple misconfiguration can leave an unprotected device exposed to the Internet, opening up the wider digital ecosystem to attack.

Breaches are inevitable, and organizations are no longer throwing all their resources into stopping an attacker from getting inside. The focus is increasingly shifting to being able to spot their behavior once they do get in, and taking autonomous action at machine speed to minimize cyber disruption.

Self-Learning AI does exactly this, learning every user and device in the organization from the ground up, without relying on static rules or signatures, and with no pre-conceptions of what constitutes a ‘threat’. And unlike humans, the technology works around the clock, without needing breaks or unwinding as the year draws to an end.

Darktrace’s AI learns ‘self’ across the entire digital estate, from the email layer, to the cloud, network, and endpoints. And crucially, Autonomous Response takes action on behalf of security teams, and can respond to ransomware in under 10 seconds, minimizing disruption, and saving teams from facing the new year with a lengthy and costly incident clean-up.

Bringing Together SOC and IR teams with Automated Threat Investigations for the Hybrid World

Default blog imageDefault blog image

The investigation gap: Why incident response is slow, fragmented and reactive

Modern investigations often fall apart the moment analysts move beyond an initial alert. Whether detections originate in cloud or on-prem environments, SOC and Incident Response (IR) teams are frequently hindered by fragmented tools and data sources, closed ecosystems, and slow, manual evidence collection just to access the forensic context they need. SOC analysts receive alerts without the depth required to confidently confirm or dismiss a threat, while IR teams struggle with inconsistent visibility across cloud, on‑premises, and contained endpoints, creating delays, blind spots, and incomplete attack timelines.

This gap between SOC and Digital Forensics and Incident Response (DFIR) slows response and forces teams into reactive and inefficient investigation patterns. Security teams struggle to collect high‑fidelity forensic data during active incidents, particularly from cloud workloads, on‑prem systems, and XDR‑contained endpoints where traditional tools cannot operate without deploying new agents or disrupting containment. The result is a fragmented response process where investigations slow down, context gets lost, and critical attacker activity can slip through the cracks.

What’s new at Darktrace

Helping teams move from detection to root cause faster, more efficiently, and with greater confidence

The latest update to Darktrace / Forensic Acquisition & Investigation eliminates the traditional handoff between the SOC and IR teams, enabling analysts to seamlessly pivot from alert into forensic investigation. It also brings on-demand and automated data capture through Darktrace / ENDPOINT as well as third-party detection platforms, where investigators can safely collect critical forensic data from network contained endpoints, preserving containment while accelerating investigation and response.  

Together, this solidifies / Forensic Acquisition & Investigation as an investigation-first platform beyond the cloud, fit for any organization that has adopted a multi-technology infrastructure. In practice, when these various detection sources and host‑level forensics are combined, investigations move from limited insight to complete understanding quickly, giving security teams the clarity and deep context required to drive confident remediation and response based on the exact tactics, techniques and procedures employed.

Integrated forensic context inside every incident workflow

SOC analysts now have seamless access to forensic evidence at the exact moment they need it. There is a new dedicated Forensics tab inside Cyber AI Analyst™ incidents, allowing users to move instantly from detection to rich forensic context in a single click, without the need to export data or get other teams involved.

For investigations that previously required multiple tools, credentials, or intervention by a dedicated team, this change represents a shift toward truly embedded incident‑driven forensics – accelerating both decision‑making and response quality at the point of detection.

Figure 1: The forensic investigation associated with the Cyber AI Analyst™ incident appears in a dedicated ‘Forensics’ tab, with the ability to pivot into the / Forensic Acquisition & Investigation UI for full context and deep analysis workflows.

Reliable automated and manual hybrid evidence capture across any environment

Across cloud, on‑premises, and hybrid environments, analysts can now automate or request on‑demand forensic evidence collection the moment a threat is detected via Darktrace / ENDPOINT. This allows investigators to quickly capture high-fidelity forensic data from endpoints already under protection, accelerating investigations without additional tooling or disrupting systems. Especially in larger environments where the ability to scale is critical, automated data capture across hybrid environments significantly reduces response time and enables consistent, repeatable investigations.

Unlike EDR‑only solutions, which capture only a narrow slice of activity, these workflows provide high‑quality, cross‑environment forensic depth, even on third‑party XDR‑contained devices that many vendor ecosystems cannot reach.

The result is a single, unified process for capturing the forensic context analysts need no matter where the threat originates, even in third-party vendor protected areas.

Investigation‑first design flexible for hybrid organizations

Luckily, taking advantage of automated forensic data capture of non-cloud assets won’t be subject to those who purely use Darktrace / ENDPOINT. This functionality is also available where CrowdStrike, Microsoft Defender for Endpoint, or SentinelOne agents are deployed.  In the case of CrowdStrike, Darktrace / Forensic Acquisition & Investigation can also perform a triage capture of a device that has been contained using CrowdStrike’s network containment capability. What’s critical here is the fact that investigators can safely acquire additional forensic evidence without breaking or altering containment. That massively improves investigation and response time without adding more risk factors.

The benefits of extending forensics to on‑premises and endpoint environments

Despite Darktrace / Forensic Acquisition & Investigation originating as a cloud‑first solution, the challenges of incident response are not limited to the cloud. Many investigations span on‑premises servers, unmanaged endpoints, legacy systems, or devices locked inside third‑party ecosystems.  

By extending automated investigation capabilities into on‑premises environments and endpoints, Darktrace delivers several critical benefits:

  • Unified investigations across hybrid infrastructure and a heterogeneous security stack
  • Consistent forensic depth regardless of asset type
  • Faster and more accurate root-cause analysis
  • Stronger incident response readiness

Figure 6: Unified alerts from cloud and on-prem environments, grouped into incident-centric investigations with forensic depth

Simplifying deep investigations across hybrid environments

These enhancements move Darktrace / Forensic Acquisition & Investigation closer to a vision out of reach for most security teams: seamless, integrated, high‑fidelity forensics across cloud, on‑prem, and endpoint environments where other solutions usually stop at detection. Automated forensics as a whole is fueling faster outcomes with complete clarity throughout the end-to-end investigation process, which now takes teams from alert to understanding in minutes compared to days or even weeks. All without added agents, disruptions, or specialized teams. The result is an incident response lifecycle that finally matches the reality of modern infrastructure.

How to Secure AI and Find the Gaps in Your Security Operations

secuing AI testing gaps security operationsDefault blog imageDefault blog image

What “securing AI” actually means (and doesn’t)

Security teams are under growing pressure to “secure AI” at the same pace which businesses are adopting it. But in many organizations, adoption is outpacing the ability to govern, monitor, and control it. When that gap widens, decision-making shifts from deliberate design to immediate coverage. The priority becomes getting something in place, whether that’s a point solution, a governance layer, or an extension of an existing platform, rather than ensuring those choices work together.

At the same time, AI governance is lagging adoption. 37% of organizations still lack AI adoption policies, shadow AI usage across SaaS has surged, and there are notable spikes in anomalous data uploads to generative AI services.  

First and foremost, it’s important to recognize the dual nature of AI risk. Much of the industry has focused on how attackers will use AI to move faster, scale campaigns, and evade detection. But what’s becoming just as significant is the risk introduced by AI inside the organization itself. Enterprises are rapidly embedding AI into workflows, SaaS platforms, and decision-making processes, creating new pathways for data exposure, privilege misuse, and unintended access across an already interconnected environment.

Because the introduction of complex AI systems into modern, hybrid environments is reshaping attacker behavior and exposing gaps between security functions, the challenge is no longer just having the right capabilities in place but effectively coordinating prevention, detection, investigation, response, and remediation together. As threats accelerate and systems become more interconnected, security depends on coordinated execution, not isolated tools, which is why lifecycle-based approaches to governance, visibility, behavioral oversight, and real-time control are gaining traction.

From cloud consolidation to AI systems what we can learn

We have seen a version of AI adoption before in cloud security. In the early days, tooling fragmented into posture, workload/runtime, identity, data, and more. Gradually, cloud security collapsed into broader cloud platforms. The lesson was clear: posture without runtime misses active threats; runtime without posture ignores root causes. Strong programs ran both in parallel and stitched the findings together in operations.  

Today’s AI wave stretches that lesson across every domain. Adversaries are compressing “time‑to‑tooling” using LLM‑assisted development (“vibecoding”) and recycling public PoCs at unprecedented speed. That makes it difficult to secure through siloed controls, because the risk is not confined to one layer. It emerges through interactions across layers.

Keep in mind, most modern attacks don’t succeed by defeating a single control. They succeed by moving through the gaps between systems faster than teams can connect what they are seeing. Recent exploitation waves like React2Shell show how quickly opportunistic actors operationalize fresh disclosures and chain misconfigurations to monetize at scale.

In the React2Shell window, defenders observed rapid, opportunistic exploitation and iterative payload diversity across a broad infrastructure footprint, strains that outpace signature‑first thinking.  

You can stay up to date on attacker behavior by signing up for our newsletter where Darktrace’s threat research team and analyst community regularly dive deep into threat finds.

Ultimately, speed met scale in the cloud era; AI adds interconnectedness and orchestration. Simple questions — What happened? Who did it? Why? How? Where else? — now cut across identities, SaaS agents, model/service endpoints, data egress, and automated actions. The longer it takes to answer, the worse the blast radius becomes.

The case for a platform approach in the age of AI

Think of security fusion as the connective tissue that lets you prevent, detect, investigate, and remediate in parallel, not in sequence. In practice, that looks like:

  1. Unified telemetry with behavioral context across identities, SaaS, cloud, network, endpoints, and email—so an anomalous action in one plane automatically informs expectations in others. (Inside‑the‑SOC investigations show this pays off when attacks hop fast between domains.)  
  1. Pre‑CVE and “in‑the‑wild” awareness feeding controls before signatures—reducing dwell time in fast exploitation windows.  
  1. Automated, bounded response that can contain likely‑malicious actions at machine speed without breaking workflows—buying analysts time to investigate with full context. (Rapid CVE coverage and exploit‑wave posts illustrate how critical those first minutes are.)  
  1. Investigation workflows that assume AI is in the loop—for both defenders and attackers. As adversaries adopt “agentic” patterns, investigations need graph‑aware, sequence‑aware reasoning to prioritize what matters early.

This isn’t theoretical. It’s reflected in the Darktrace posts that consistently draw readership: timely threat intel with proprietary visibility and executive frameworks that transform field findings into operating guidance.  

The five questions that matter (and the one that matters more)

When alerted to malicious or risky AI use, you’ll ask:

  1. What happened?
  1. Who did it?
  1. Why did they do it?
  1. How did they do it?
  1. Where else can this happen?

The sixth, more important question is: How much worse does it get while you answer the first five? The answer depends on whether your controls operate in sequence (slow) or in fused parallel (fast).

What to watch next: How the AI security market will likely evolve

Security markets tend to follow a familiar pattern. New technologies drive an initial wave of specialized tools (posture, governance, observability) each focused on a specific part of the problem. Over time, those capabilities consolidate as organizations realize the new challenge is coordination.

AI is accelerating the shift of focus to coordination because AI-powered attackers can move faster and operate across more systems at once. Recent exploitation waves show exactly this. Adversaries can operationalize new techniques and move across domains, turning small gaps into full attack paths.

Anticipate a continued move toward more integrated security models because fragmented approaches can’t keep up with the speed and interconnected nature of modern attacks.

Building the Groundwork for Secure AI: How to Test Your Stack’s True Maturity

AI doesn’t create new surfaces as much as it exposes the fragility of the seams that already exist.  

Darktrace’s own public investigations consistently show that modern attacks, from LinkedIn‑originated phishing that pivots into corporate SaaS to multi‑stage exploitation waves like BeyondTrust CVE‑2026‑1731 and React2Shell, succeed not because a single control failed, but because no control saw the whole sequence, or no system was able to respond at the speed of escalation.  

Before thinking about “AI security,” customers should ensure they’ve built a security foundation where visibility, signals, and responses can pass cleanly between domains. That requires pressure‑testing the seams.

Below are the key integration questions and stack‑maturity tests every organization should run.

1. Do your controls see the same event the same way?

Integration questions

  • When an identity behaves strangely (impossible travel, atypical OAuth grants), does that signal automatically inform your email, SaaS, cloud, and endpoint tools?
  • Do your tools normalize events in a way that lets you correlate identity → app → data → network without human stitching?

Why it matters

Darktrace’s public SOC investigations repeatedly show attackers starting in an unmonitored domain, then pivoting into monitored ones, such as phishing on LinkedIn that bypassed email controls but later appeared as anomalous SaaS behavior.

If tools can’t share or interpret each other's context, AI‑era attacks will outrun every control.

Tests you can run

  1. Shadow Identity Test
  • Create a temporary identity with no history.
  • Perform a small but unusual action: unusual browser, untrusted IP, odd OAuth request.
  • Expected maturity signal: other tools (email/SaaS/network) should immediately score the identity as high‑risk.
  1. Context Propagation Test
  • Trigger an alert in one system (e.g., endpoint anomaly) and check if other systems automatically adjust thresholds or sensitivity.
  • Low maturity signal: nothing changes unless an analyst manually intervenes.

2. Does detection trigger coordinated action, or does everything act alone?

Integration questions

  • When one system blocks or contains something, do other systems automatically tighten, isolate, or rate‑limit?
  • Does your stack support bounded autonomy — automated micro‑containment without broad business disruption?

Why it matters

In public cases like BeyondTrust CVE‑2026‑1731 exploitation, Darktrace observed rapid C2 beaconing, unusual downloads, and tunneling attempts across multiple systems. Containment windows were measured in minutes, not hours.  

Tests you can run

  1. Chain Reaction Test
  • Simulate a primitive threat (e.g., access from TOR exit node).
  • Your identity provider should challenge → email should tighten → SaaS tokens should re‑authenticate.
  • Weak seam indicator: only one tool reacts.
  1. Autonomous Boundary Test
  • Induce a low‑grade anomaly (credential spray simulation).
  • Evaluate whether automated containment rules activate without breaking legitimate workflows.

3. Can your team investigate a cross‑domain incident without swivel‑chairing?

Integration questions

  • Can analysts pivot from identity → SaaS → cloud → endpoint in one narrative, not five consoles?
  • Does your investigation tooling use graphs or sequence-based reasoning, or is it list‑based?

Why it matters

Darktrace’s Cyber AI Analyst and DIGEST research highlights why investigations must interpret structure and progression, not just standalone alerts. Attackers now move between systems faster than human triage cycles.  

Tests you can run

  1. One‑Hour Timeline Build Test
  • Pick any detection.
  • Give an analyst one hour to produce a full sequence: entry → privilege → movement → egress.
  • Weak seam indicator: they spend >50% of the hour stitching exports.
  1. Multi‑Hop Replay Test
  • Simulate an incident that crosses domains (phish → SaaS token → data access).
  • Evaluate whether the investigative platform auto‑reconstructs the chain.

4. Do you detect intent or only outcomes?

Integration questions

  • Can your stack detect the setup behaviors before an attack becomes irreversible?
  • Are you catching pre‑CVE anomalies or post‑compromise symptoms?

Why it matters

Darktrace publicly documents multiple examples of pre‑CVE detection, where anomalous behavior was flagged days before vulnerability disclosure. AI‑assisted attackers will hide behind benign‑looking flows until the very last moment.

Tests you can run

  1. Intent‑Before‑Impact Test
  • Simulate reconnaissance-like behavior (DNS anomalies, odd browsing to unknown SaaS, atypical file listing).
  • Mature systems will flag intent even without an exploit.
  1. CVE‑Window Test
  • During a real CVE patch cycle, measure detection lag vs. public PoC release.
  • Weak seam indicator: your detection rises only after mass exploitation begins.

5. Are response and remediation two separate universes?

Integration questions

  • When you contain something, does that trigger root-cause remediation workflows in identity, cloud config, or SaaS posture?
  • Does fixing a misconfiguration automatically update correlated controls?

Why it matters

Darktrace’s cloud investigations (e.g., cloud compromise analysis) emphasize that remediation must close both runtime and posture gaps in parallel.

Tests you can run

  1. Closed‑Loop Remediation Test
  • Introduce a small misconfiguration (over‑permissioned identity).
  • Trigger an anomaly.
  • Mature stacks will: detect → contain → recommend or automate posture repair.
  1. Drift‑Regression Test
  • After remediation, intentionally re‑introduce drift.
  • The system should immediately recognize deviation from known‑good baseline.

6. Do SaaS, cloud, email, and identity all agree on “normal”?

Integration questions

  • Is “normal behavior” defined in one place or many?
  • Do baselines update globally or per-tool?

Why it matters

Attackers (including AI‑assisted ones) increasingly exploit misaligned baselines, behaving “normal” to one system and anomalous to another.

Tests you can run

  1. Baseline Drift Test
  • Change the behavior of a service account for 24 hours.
  • Mature platforms will flag the deviation early and propagate updated expectations.
  1. Cross‑Domain Baseline Consistency Test
  • Compare identity’s risk score vs. cloud vs. SaaS.
  • Weak seam indicator: risk scores don’t align.

Final takeaway

Security teams should ask be focused on how their stack operates as one system before AI amplifies pressure on every seam.

Only once an organization can reliably detect, correlate, and respond across domains can it safely begin to secure AI models, agents, and workflows.
