As an industry, the constant stream of cyber-attacks in the news can be overwhelming. It seems like every day we see front-page headlines announcing defaced websites or massive data breaches.

But what about the attacks that never make the news?

Here at Darktrace, our worldwide deployments find early-stage threats every day. While these developing threats never make the headlines, they often emerge in fascinating and unexpected ways.

Here’s a selection of what we’ve found for our customers:

       
  1. An attacker hacked into a biometric fingerprint scanner used for physical access at a major manufacturing company.
       This company used network-connected fingerprint scanners, allowing the attacker to use Telnet connections and default credentials to gain access. There were strong indiciators that the attacker was able to use the device to breach other servers.
  2.    
  3. A cyber-criminal gained access to a video conferencing system of a multi-national corporation.
       Using a backdoor Trojan Horse, the attacker used six external computers to collect data from the camera, presumably in an attempt to steal video from confidential meetings.
  4.    
  5. A new strain of malware forced the computers of a security company to visit explicit websites.
       Using random, algorithmically-generated websites, the attackers tried to plant incriminating evidence on the network by generating illegal web activity.
  6.    
  7. A threat-actor hacked a ‘Lost and Found’ computer at a major European airport.
       To gain entry, the attacker used DNS servers, an essential capability for internet communication though rarely used for information transfer.
  8.    
  9. A hacker tried to compromise an industrial power network using default codes.
       After penetrating the SCADA energy network, the attacker tried to establish a remote control link by using access codes listed as factory defaults online.
  10.    
  11. A phishing email launched a ransomware attack on a non-profit charity.
       Using a fake email, the attacker claimed to have an invoice from a legitimate supplier. The attached pdf contacted a server in Ukraine and downloaded malware attempting to encrypt the non-profit’s network.

Our ‘immune system’ technology caught each attack at an extremely early stage, giving us a rare look at how modern threats are able to bypass legacy systems. Traditional security solutions can only detect attacks with pre-determined signatures. But in each case, threat-actors used signature-less attacks to blend into the noise of the network.

By harnessing the power of unsupervised machine learning, the Enterprise Immune System learned ‘normal’ for each of these networks, and detected the threats as anomalous behavior. Our threat analysts then determined the nature of the attack and counseled the organization to take appropriate action.

We look forward to sharing more of our industry insights with you in the future.

Your Vendors, Your Risk: Rethinking Third-Party Security in the Age of Supply Chain Attacks

man on cellphoneDefault blog imageDefault blog image

When most people hear the term supply chain attack, they often imagine a simple scenario: one organization is compromised, and that compromise is used as a springboard to attack another. This kind of lateral movement is common, and often the entry vector is as mundane and as dangerous as email.

Take, for instance, a situation where a trusted third-party vendor is breached. An attacker who gains access to their systems can then send malicious emails to your organization, emails that appear to come from a known and reputable source. Because the relationship is trusted, traditional phishing defenses may not be triggered, and recipients may be more inclined to engage with malicious content. From there, the attacker can establish a foothold, move laterally, escalate privileges, and launch a broader campaign.

This is one dimension of a supply chain cyber-attack, and it’s well understood in many security circles. But the risk doesn’t end there. In fact, it goes deeper, and it often hits the most important asset of all: your customers' data.

The risk beyond the inbox

What happens when customer data is shared with a third party for legitimate processing purposes for example billing, analytics, or customer service and that third party is then compromised?

In that case, your customer data is breached, even if your own systems were never touched. That’s the uncomfortable truth about modern cybersecurity: your risk is no longer confined to your own infrastructure. Every entity you share data with becomes an extension of your attack surface. Thus, we should rethink how we perceive responsibility.

It’s tempting to think that securing our environment is our job, and securing their environment is theirs. But if a breach of their environment results in the exposure of our customers, the accountability and reputational damage fall squarely on our shoulders.

The illusion of boundaries

In an era where digital operations are inherently interconnected, the lines of responsibility can blur quickly. Legally and ethically, organizations are still responsible for the data they collect even if that data is processed, stored, or analyzed by a third party. A customer whose data is leaked because of a vendor breach will almost certainly hold the original brand responsible, not the third-party processor they never heard of.

This is particularly important for industries that rely on extensive outsourcing and platform integrations (SaaS platforms, marketing tools, CRMs, analytics platforms, payment processors). The list of third-party vendors with access to customer data grows year over year. Each integration adds convenience, but also risk.

Encryption isn’t a silver bullet

One of the most common safeguards used in these data flows is encryption. Encrypting customer data in transit is a smart and necessary step, but it’s far from enough. Once data reaches the destination system, it typically needs to be decrypted for use. And the moment it is decrypted, it becomes vulnerable to a variety of attacks like ransomware, data exfiltration, privilege escalation, and more.

In other words, the question isn’t just is the data secure in transit? The more important question is how is it protected once it arrives?

A checklist for organizations evaluating third-parties

Given these risks, what should responsible organizations do when they need to share customer data with third parties?

Start by treating third-party security as an extension of your own security program. Here are some foundational controls that can make a difference:

Due diligence before engagement: Evaluate third-party vendors based on their security posture before signing any contracts. What certifications do they hold? What frameworks do they follow? What is their incident response capability?

Contractual security clauses: Build in specific security requirements into vendor contracts. These can include requirements for encryption standards, access control policies, and data handling protocols.

Third-party security assessments: Require vendors to provide evidence of their security controls. Independent audits, penetration test results, and SOC 2 reports can all provide useful insights.

Ongoing monitoring and attestations: Security isn’t static. Make sure vendors provide regular security attestations and reports. Where possible, schedule periodic reviews or audits, especially for vendors handling sensitive data.

Minimization and segmentation: Don’t send more data than necessary. Data minimization limits the exposure in the event of a breach. Segmentation, both within your environment and within vendor access levels, can further reduce risk.

Incident response planning: Ensure you have a playbook for handling third-party incidents, and that vendors do as well. Coordination in the event of a breach should be clear and rapid.

The human factor: Customers and communication

There’s another angle to supply chain cyber-attacks that’s easy to overlook: the post-breach exploitation of public knowledge. When a breach involving customer data hits the news, it doesn’t take long for cybercriminals to jump on the opportunity.

Attackers can craft phishing emails that appear to be follow-ups from the affected organization: “Click here to reset your password,” “Confirm your details due to the breach,” etc.

A breach doesn’t just put customer data at risk it also opens the door to further fraud, identity theft, and financial loss through social engineering. This is why post-breach communication and phishing mitigation strategies are valuable components of an incident response strategy.

Securing what matters most

Ultimately, protecting against supply chain cyber-attacks isn’t just about safeguarding your own perimeter. It’s about defending the integrity of your customers’ data, wherever it goes. When customer data is entrusted to you, the duty of care doesn’t end at your firewall.

Relying on vendors to “do their part” is not enough. True due diligence means verifying, validating, and continuously monitoring those extended attack surfaces. It means designing controls that assume failure is possible, and planning accordingly.

In today’s threat landscape, cybersecurity is no longer just a technical discipline. It’s a trust-building exercise. Your customers expect you to protect their information, and rightly so. And when a supply chain attack happens, whether the breach originated with you or your partner, the damage lands in the same place: your brand, your customers, your responsibility.

Enhanced Defense Across the Modern Network

Modern networks are expanding far beyond on-premises into virtual environments, cloud and hybrid networks. More than 50% of incidents will come from cloud network activity by 2029, meaning defenders need a solution that can level the playing field against complex attacks that traverse multiple areas of a digital estate, including north-south and east-west traffic.

With Azure Virtual Network TAP, Darktrace’s self-learning AI gains seamless access to granular packet data in hybrid environments. This integration helps our Cyber AI platform build a comprehensive understanding of a customers’ Azure network. Microsoft's recent enhancement allows Virtual Network TAP to mirror the full throughput of VMs without impacting VM bandwidth, enabling agentless Cyber AI defense across these instances.

Darktrace's Cyber AI provides real-time visibility and adaptive, autonomous defense for your Microsoft security strategy. Our platform continuously learns the normal behavior of every user, device, and workload in your environment. This deep understanding of usual 'patterns of life' enables Darktrace to detect subtle deviations that indicate threats, from account takeovers to critical misconfigurations.

Our bespoke, real-time knowledge of usual activity allows Darktrace to identify unknown and unpredictable threats that bypass policy-based defenses—without relying on rules, signatures, or prior assumptions. This approach is a powerful compliment to Microsoft’s unprecedented threat intelligence.

Expanding Azure Virtual Network TAP

Azure Virtual Network TAP allows continuous streaming of virtual machine network traffic, which customers can leverage for Darktrace’s AI-driven threat detection and investigation. Darktrace / NETWORK passively ingests traffic from on-premises, virtual, cloud, hybrid environments, and remote devices, analyzing both encrypted and decrypted packets to uncover unusual activity in real-time.
