During an initial demo with a water management company, Darktrace found an industrial control system exposed to the internet. Immediately, the organization went into incident response mode because this system was mission critical and could potentially impact the water facilities, as it had the power to adjust water flow.

This asset was exposed because of a simple misconfiguration, highlighting to the customer the need for proactive monitoring of its attack surface. In this case, the engineer who set up the system had simply not noticed the mistake, but these scenarios could be more dangerous and more likely if insider threat is involved.  

The growing threat of misconfigurations in cybersecurity

Misconfigurations arise when vital security settings are either not applied or applied incorrectly. Such misconfigurations produce vulnerable security openings that can be exploited by attackers to either gain a foothold in the asset or generate a more dangerous attack, like altering water flow or deploying ransomware. There is a wide variety of assets that are subject to potential misconfigurations, including web or application servers, cloud containers, custom code, network devices like desktops or servers, and entire databases.  

Unfortunately, the pervasiveness of misconfigurations is only increasing. In the past 12 months, there has been a 310% increase in hackers reporting misconfiguration vulnerabilities to the HackerOne platform.  

Unique risks for industrial control systems and critical infrastructure

Every digital environment has its own characteristics that alter the prevalence or the impact of misconfigurations. For example, industrial devices that support critical infrastructure are all the more sensitive to these types of changes, as these devices often have limited integrated security, despite their highly delicate functions. Because with every vendor and device has its own recommended configuration, security teams must take additional precautions.  

In cloud environments, the ease of deployment and increased capabilities also tend to produce more misconfigurations. Digital footprints are growing at such a pace that security departments may opt to skip onboarding processes of technologies to avoid becoming an obstacle for the business. It has become so easy for any department, regardless of their technical knowledge, to add cloud applications, software, or even hardware to the company's architecture. This is why shadow IT is so troublesome: it's impossible for the security team to ensure something is well configured if they don’t even know it exists.  

In addition, due to rapid growth, security and IT teams aren’t experts in every technology included within the enterprise architecture. So, the teams may do their best to apply security controls while being unaware the current configuration is a misconfiguration. With digital assets’ constant evolution, they may even be configured correctly at one point but become misconfigured in the future if not updated.  

Mitigating Misconfiguration

It’s human nature that we make mistakes, and the more assets and third parties that are introduced, the more mistakes are possible. However, there are certain steps organizations can take towards reducing the frequency and the impact of misconfigurations.  

Any organization needs to have discovery processes to maintain an updated inventory of their assets, and should categorize these assets based on their exposure as well as their criticality to the business. This information should feed into the organization’s risk analysis, which in turn informs the priority of mitigation actions or controls. This process, when done manually, can be long and arduous, and is not continuous: as organizations’ digital footprints are evolving so rapidly, these analyses can become obsolete quickly.  

On the other hand, organizations must also monitor the activity of these assets and not just assess them at face value. As with anything in security, security teams need to be weary of the symptoms. Inappropriate configurations will often generate alerts such as slow performance, multiple suspicious login attempts, bloatware, unexpected application behavior such as redirects or shutdowns.  

Misconfigurations are easier to identify, prioritize and remediate with an AI solution that provides continuous analysis of the organization’s external and internal attack surface. Darktrace / Proactive Exposure Management and Darktrace / Attack Surface Management achieve exactly this.  

Managing external assets

With ASM, security teams gain visibility of the entire external attack surface, including elusive assets like shadow IT and legacy devices. It frequently uncovers misconfigurations and recommends how to mitigate the risks caused by them. Some examples include email spoofing, no SPF records, no DKIM records, no DMARC records, subdomain takeover possible, and missing routes for netblocks.  

The truly unique aspect of a Self-Learning technology is that security teams receive notifications tailored to the precise assets within their architectures. In other words, the tool will only provide the misconfiguration recommendations for the specific assets that require it, instead of having to reverse engineer state-of-the-art security and then trying to see where it can apply within the organization. With Darktrace, security teams are already getting that information directly. In fact, it doesn’t stop there, misconfigurations are prirotized by the risk inherited. The security team only has to check the list of misconfigurations in order of priority and take action on them.  

Exposure management & attack paths

From an internal perspective, Darktrace / Proactive Exposure Management will map those misconfigurations to potential attack paths, answering the question of what damage each misconfiguration can lead to and more importantly how: an attacker could go from that initial misconfiguration through each lateral movement, whether it is via a device or a user, and then reach the most critical devices within the infrastructure.

Often in security, the focus can drift to the latest tactics and techniques being used by large Advanced Persistent Threats, but a simple misconfiguration caused by a rushed or distracted employee can pose an equally large threat. An innocent mistake can often open an even larger weakness in the digital architecture, as the attacker doesn’t have to force to open the window to break in.

Anomaly-based threat hunting: Darktrace's approach in action

person working on laptopDefault blog imageDefault blog image

What is threat hunting?

Threat hunting in cybersecurity involves proactively and iteratively searching through networks and datasets to detect threats that evade existing automated security solutions. It is an important component of a strong cybersecurity posture.

There are several frameworks that Darktrace analysts use to guide how threat hunting is carried out, some of which are:

  • MITRE Attack
  • Tactics, Techniques, Procedures (TTPs)
  • Diamond Model for Intrusion Analysis
  • Adversary, Infrastructure, Victims, Capabilities
  • Threat Hunt Model – Six Steps
  • Purpose, Scope, Equip, Plan, Execute, Feedback
  • Pyramid of Pain

These frameworks are important in baselining how to run a threat hunt. There are also a combination of different methods that allow defenders diversity– regardless of whether it is a proactive or reactive threat hunt. Some of these are:

  • Hypothesis-based threat hunting
  • Analytics-driven threat hunting
  • Automated/machine learning hunting
  • Indicator of Compromise (IoC) hunting
  • Victim-based threat hunting

Threat hunting with Darktrace

At its core, Darktrace relies on anomaly-based detection methods. It combines various machine learning types that allows it to characterize what constitutes ‘normal’, based on the analysis of many different measures of a device or actor’s behavior. Those types of learning are then curated into what are called models.

Darktrace models leverage anomaly detection and integrate outputs from Darktrace Deep Packet Inspection, telemetry inputs, and additional modules, creating tailored activity detection.

This dynamic understanding allows Darktrace to identify, with a high degree of precision, events or behaviors that are both anomalous and unlikely to be benign.  On top of machine learning models for detection, there is also the ability to change and create models showcasing the tool’s diversity. The Model Editor allows security teams to specify values, priorities, thresholds, and actions they want to detect. That means a team can create custom detection models based on specific use cases or business requirements. Teams can also increase the priority of existing detections based on their own risk assessments to their environment.

This level of dexterity is particularly useful when conducting a threat hunt. As described above, and in previous ‘Inside the SOC’ blogs such a threat hunt can be on a specific threat actor, specific sector, or a  hypothesis-based threat hunt combined with ‘experimenting’ with some of Darktrace’s models.

Conducting a threat hunt in the energy sector with experimental models

In Darktrace’s recent Threat Research report “AI & Cybersecurity: The state of cyber in UK and US energy sectors” Darktrace’s Threat Research team crafted hypothesis-driven threat hunts, building experimental models and investigating existing models to test them and detect malicious activity across Darktrace customers in the energy sector.

For one of the hunts, which hypothesised utilization of PerfectData software and multi-factor authentication (MFA) bypass to compromise user accounts and destruct data, an experimental model was created to detect a Software-as-a-Service (SaaS) user performing activity relating to 'PerfectData Software’, known to allow a threat actor to exfiltrate whole mailboxes as a PST file. Experimental model alerts caused by this anomalous activity were analyzed, in conjunction with existing SaaS and email-related models that would indicate a multi-stage attack in line with the hypothesis.

Whilst hunting, Darktrace researchers found multiple model alerts for this experimental model associated with PerfectData software usage, within energy sector customers, including an oil and gas investment company, as well as other sectors. Upon further investigation, it was also found that in June 2024, a malicious actor had targeted a renewable energy infrastructure provider via a PerfectData Software attack and demonstrated intent to conduct an Operational Technology (OT) attack.

The actor logged into Azure AD from a rare US IP address. They then granted Consent to ‘eM Client’ from the same IP. Shortly after, the actor granted ‘AddServicePrincipal’ via Azure to PerfectData Software. Two days later, the actor created a  new email rule from a London IP to move emails to an RSS Feed Folder, stop processing rules, and mark emails as read. They then accessed mail items in the “\Sent” folder from a malicious IP belonging to anonymization network,  Private Internet Access Virtual Private Network (PIA VPN) [1]. The actor then conducted mass email deletions, deleting multiple instances of emails with subject “[Name] shared "[Company Name] Proposal" With You” from the  “\Sent folder”. The emails’ subject suggests the email likely contains a link to file storage for phishing purposes. The mass deletion likely represented an attempt to obfuscate a potential outbound phishing email campaign.

The Darktrace Model Alert that triggered for the mass deletes of the likely phishing email containing a file storage link.

A month later, the same user was observed downloading mass mLog CSV files related to proprietary and Operational Technology information. In September, three months after the initial attack, another mass download of operational files occurred by this actor, pertaining to operating instructions and measurements, The observed patience and specific file downloads seemingly demonstrated an intent to conduct or research possible OT attack vectors. An attack on OT could have significant impacts including operational downtime, reputational damage, and harm to everyday operations. Darktrace alerted the impacted customer once findings were verified, and subsequent actions were taken by the internal security team to prevent further malicious activity.

Conclusion

Harnessing the power of different tools in a security stack is a key element to cyber defense. The above hypothesis-based threat hunt and custom demonstrated intent to conduct an experimental model creation demonstrates different threat hunting approaches, how Darktrace’s approach can be operationalized, and that proactive threat hunting can be a valuable complement to traditional security controls and is essential for organizations facing increasingly complex threat landscapes.

Combatting the Top Three Sources of Risk in the Cloud

woman working on laptopDefault blog imageDefault blog image

With cloud computing, organizations are storing data like intellectual property, trade secrets, Personally Identifiable Information (PII), proprietary code and statistics, and other sensitive information in the cloud. If this data were to be accessed by malicious actors, it could incur financial loss, reputational damage, legal liabilities, and business disruption.

Last year data breaches in solely public cloud deployments were the most expensive type of data breach, with an average of $5.17 million USD, a 13.1% increase from the year before.

So, as cloud usage continues to grow, the teams in charge of protecting these deployments must understand the associated cybersecurity risks.

What are cloud risks?

Cloud threats come in many forms, with one of the key types consisting of cloud risks. These arise from challenges in implementing and maintaining cloud infrastructure, which can expose the organization to potential damage, loss, and attacks.

There are three major types of cloud risks:

1. Misconfigurations

As organizations struggle with complex cloud environments, misconfiguration is one of the leading causes of cloud security incidents. These risks occur when cloud settings leave gaps between cloud security solutions and expose data and services to unauthorized access. If discovered by a threat actor, a misconfiguration can be exploited to allow infiltration, lateral movement, escalation, and damage.

With the scale and dynamism of cloud infrastructure and the complexity of hybrid and multi-cloud deployments, security teams face a major challenge in exerting the required visibility and control to identify misconfigurations before they are exploited.

Common causes of misconfiguration come from skill shortages, outdated practices, and manual workflows. For example, potential misconfigurations can occur around firewall zones, isolated file systems, and mount systems, which all require specialized skill to set up and diligent monitoring to maintain

2. Identity and Access Management (IAM) failures

IAM has only increased in importance with the rise of cloud computing and remote working. It allows security teams to control which users can and cannot access sensitive data, applications, and other resources.

Cybersecurity professionals ranked IAM skills as the second most important security skill to have, just behind general cloud and application security.

There are four parts to IAM: authentication, authorization, administration, and auditing and reporting. Within these, there are a lot of subcomponents as well, including but not limited to Single Sign-On (SSO), Two-Factor Authentication (2FA), Multi-Factor Authentication (MFA), and Role-Based Access Control (RBAC).

Security teams are faced with the challenge of allowing enough access for employees, contractors, vendors, and partners to complete their jobs while restricting enough to maintain security. They may struggle to track what users are doing across the cloud, apps, and on-premises servers.

When IAM is misconfigured, it increases the attack surface and can leave accounts with access to resources they do not need to perform their intended roles. This type of risk creates the possibility for threat actors or compromised accounts to gain access to sensitive company data and escalate privileges in cloud environments. It can also allow malicious insiders and users who accidentally violate data protection regulations to cause greater damage.

3. Cross-domain threats

The complexity of hybrid and cloud environments can be exploited by attacks that cross multiple domains, such as traditional network environments, identity systems, SaaS platforms, and cloud environments. These attacks are difficult to detect and mitigate, especially when a security posture is siloed or fragmented.  

Some attack types inherently involve multiple domains, like lateral movement and supply chain attacks, which target both on-premises and cloud networks.  

Challenges in securing against cross-domain threats often come from a lack of unified visibility. If a security team does not have unified visibility across the organization’s domains, gaps between various infrastructures and the teams that manage them can leave organizations vulnerable.

Adopting AI cybersecurity tools to reduce cloud risk

For security teams to defend against misconfigurations, IAM failures, and insecure APIs, they require a combination of enhanced visibility into cloud assets and architectures, better automation, and more advanced analytics. These capabilities can be achieved with AI-powered cybersecurity tools.

Such tools use AI and automation to help teams maintain a clear view of all their assets and activities and consistently enforce security policies.
