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.

Darktrace Collaborates with Microsoft: Unifying Email Security with a Shared Vision

Default blog imageDefault blog image

In today’s threat landscape, email remains the most targeted vector for cyberattacks. Organizations require not only multi-layered defenses but also advanced, integrated systems that work collaboratively to proactively mitigate threats before they cause damage

That’s why we’re proud to announce a new integration between Darktrace / EMAIL and Microsoft Defender for Office 365, delivering a Unified Quarantine experience that empowers security teams with seamless visibility, control, and response across both platforms.

This announcement builds on a strong and growing collaboration. In 2024, Darktrace was honored as Microsoft UK Partner of the Year and recognized as a Security Trailblazer at the annual Microsoft Security 20/20 Awards, a testament to our shared commitment to innovation and customer-centric security.

A Shared Mission: Stopping Threats at Machine Speed

This integration is more than a technical milestone,as it’s a reflection of a shared mission: to protect organizations from both known and unknown threats, with efficiency, accuracy, and transparency.

  • Microsoft Defender for Office 365 delivers a comprehensive security framework that safeguards Microsoft 365 email and collaboration workloads leveraging advanced AI, global threat intelligence and information on known attack infrastructure.
  • Darktrace / EMAIL complements this with Self-Learning AI that understands the unique communication patterns within each organization, detecting subtle anomalies that evade traditional detection methods.

Together, we’re delivering multi-layered, adaptive protection that’s greater than the sum of its parts.

“Our integration with Microsoft gives security teams the tools they need to act faster and more precisely to detect and respond to threats,” said Jill Popelka, CEO of Darktrace. “Together, we’re strengthening defenses where it matters most to our customers: at the inbox.”

Unified Quarantine: One View, Total Clarity

The new Unified Quarantine experience gives customers a single pane of glass to view and manage email threatsregardless of which product took action. This means:

  • Faster investigations with consolidated visibility
  • Clear attribution of actions and outcomes across both platforms
  • Streamlined workflows for security teams managing complex environments

“This integration is a testament to the power of combining Microsoft’s global threat intelligence with Darktrace’s unique ability to understand the ‘self’ of an organization,” said Jack Stockdale, CTO of Darktrace. “Together, we’re delivering a new standard in proactive, adaptive email security.”

A New Era of Collaborative Cyber Defense

This collaboration represents a broader shift in cybersecurity: from siloed tools to integrated ecosystems. As attackers become more sophisticated, defenders must move faster, smarter, and in unison.

Through this integration, Darktrace and Microsoft establish a new standard for collaboration between native and third-party security solutions, enhancing not only threat detection but also comprehensive understanding and proactive measures against threats.

We’re excited to bring this innovation to our customers and continue building a future where AI and human expertise collaborate to secure the enterprise.

Customer Case Study: Leading Petrochemical Manufacturer

Default blog imageDefault blog image

Headquartered in Saudi Arabia, this industry leading petrochemical manufacturer serves customers in more than 80 countries across diverse markets throughout Europe, Africa, Latin America, the Middle East, China, and Southeast Asia.

Cyber resiliency critical to growth strategy

This leading petrochemical manufacturer’s vision is to be one of the major global players in the production and marketing of designated petrochemicals and downstream products. The company aims to significantly increase its capacity to up to a million metric tons within the next few years.

With cyber-attacks on critical infrastructure increasing 30% globally last year, cyber resiliency is essential to supporting the company’s strategic business goals of:

  • Maximizing production through efficient asset utilization
  • Maximizing sales by conducting 90% of its business outside Saudi Arabia
  • Optimizing resources and processes by integrating with UN Global Compact principles for sustainability and efficiency
  • Growing its business portfolio by engaging in joint ventures to diversify production and add value to the economy

However, the industry leader faced several challenges in its drive to fortify its cybersecurity defenses.

Visibility gaps delay response time

The company’s existing security setup provided limited visibility to the in-house security team, hindering its ability to detect anomalous network and user activity in real time. This resulted in delayed responses to potential incidents, making proactive issue resolution difficult and any remediation in the event of a successful attack costly and time-consuming.

Manual detection drains resources

Without automated detection and response capabilities, the organization’s security team had to manually monitor for suspicious activity – a time-consuming and inefficient approach that strained resources and left the organization vulnerable. This made it difficult for the team to stay current with training or acquire new skills and certifications, which are core to the ethos of both the company’s owners and the team itself.

Cyber-attacks on critical infrastructure increasing

The petrochemical manufacturer is part of a broader ecosystem of companies, making the protection of its supply chain – both upstream and downstream – critical. With several manufacturing entities and multiple locations, the customer’s internal structure is complex and challenging to secure. As cyber-attacks on critical infrastructure escalate, it needed a more comprehensive approach to safeguard its business and the wider ecosystem.

Keeping and growing skills and focus in-house

To strengthen its cybersecurity strategy, the company considered two options:

  1. Make a significant initial and ongoing investment in a Security Operations Center (SOC), which would involve skills development outside the company and substantial management overhead.
  2. Use a combination of new, automated tools and an outsourced Managed Detection and Response (MDR) service to reduce the burden on internal security specialists and allow the company to invest in upskilling its staff so they can focus on more strategic tasks.

Faced with this choice between entirely outsourcing security and augmenting the security team with new capabilities, the customer chose the second option, selecting Darktrace to automate the company’s monitoring, detection, and response. Today, the petrochemical manufacturer is using:

Extending the SOC with 24/7 expert support

To alleviate the burden on its lean security team, the company augmented its in-house capabilities with Darktrace’s Managed Detection & Response service. This support acts as an extension of its SOC, providing 24/7 monitoring, investigation, and escalation of high-priority threats. With Darktrace’s global SOC managing alert triage and autonomously containing threats, the organization’s internal team can focus on strategic initiatives. The result is a stronger security posture and increased capacity to proactively address evolving cyber risks – without expanding headcount or sacrificing visibility.

A unique approach to AI

In its search for a new security platform, the company’s Director of Information Technology said Darktrace’s autonomous response capability, coupled with Self-Learning AI-driven threat reduction, were two big reasons for selecting Darktrace over competing products and services.

AI was a huge factor – no one else was doing what Darktrace was doing with [AI].”

Demonstrated visibility

Before Darktrace, the customer had no visibility into the network activity to and from remote worker devices. Some employees need the ability to connect to its networks at any time and from any location, including the Director of Information Technology. The trial deployment of Darktrace / ENDPOINT was a success and gave the team peace of mind that, no matter the location or device, high-value remote workers were protected by Darktrace.

Modular architecture  

Darktrace's modular architecture allowed the company to deploy security controls across its complex, multi-entity environment. The company’s different locations run on segregated networks but are still interconnected and need to be protected. Darktrace / NETWORK provides a unified view and coordinated security response across the organization’s entire network infrastructure, including endpoint devices.

Results

The petrochemical manufacturer is using Darktrace across all of its locations and has achieved total visibility across network and user activity. “Darktrace is increasing in value every day,” said the Director of Information Technology.

I don’t have a big team, and Darktrace makes our lives very, very easy, not least the automation of some of the tasks that require constant manual review.”

Time savings frees analysts to focus on proactive security

Darktrace / NETWORK provides continuous, AI-driven monitoring and analysis of the company’s network activity, user behavior, and threat patterns, establishing a baseline of what normal activity looks like, and then alerting analysts to any deviations from normal traffic, activity, and behaviors. Darktrace’s autonomous response capabilities speed up response to detected threats, meaning intervention from the security team is required for fewer incidents and alerts.

In October 2024 alone, Darktrace Cyber AI Analyst saved the team 810 investigation hours, and autonomously responded to 180 anomalous behaviors that were uncovered during the investigations. With Darktrace managing the majority of threat detection and response efforts, the security team has been able to change its day-to-day activity from manual review of traffic and alerts and belated response to activity, to proactively fortifying its detection and response posture and upskilling to meet evolving requirements.  

Layered email protection reduces phishing threats

The company’s email infrastructure posed a challenge due to petrochemical industry regulations requiring on-premises email servers, with some security delivered via Microsoft Azure. By integrating Darktrace / EMAIL into the Azure stack, the organization has reduced the volume of phishing emails its users receive by 5%.

“Now we have one more layer of security related to email – every email goes through two filters. If something is not being caught or traced by Azure, it is being detected by Darktrace,” said the Director of Information Technology. “As a result, we’re now seeing only about 15% to 20% of the phishing emails we used to receive before implementing Darktrace.”

Preparing for a secure future

The time saved using Darktrace has helped the security team take proactive steps, including preparing for new cyber resilience regulations for Saudi Arabia’s Critical National Infrastructure, as mandated by the National Cybersecurity Authority (NCA).

“The team now has ample time to prepare policies and procedures that meet the new NCA regulations and, in some cases, enhance the requirements of the new law,” said the Director of Information Technology. “All of this is possible because they don’t need to keep watch; Darktrace takes on so much of that task for them.”
