Human Resources Collaboration for Early Threat Detection

Implement a process whereby HR data and observations, including those from managers and colleagues, can be securely communicated in a timely manner to investigators, triggering proactive monitoring of potential insider threats early in their lifecycle. Collaboration between HR teams, managers, colleagues, and investigators is essential for detecting concerning behaviors or changes in an employee's personal circumstances that could indicate an increased risk of insider threat.

 

Mental Health and Personal Struggles

  • Trigger Event: HR receives reports or observes a significant change in an employee's behavior or performance, which may indicate mental health issues or personal struggles that could elevate the likelihood of an insider threat. This information may come from managers, colleagues, or direct observations within HR.
  • Indicator: Multiple reports from managers, direct supervisors, or colleagues highlighting behavior changes such as stress, depression, or erratic actions.
  • Response: HR teams should notify investigators of high-risk employees with visible signs of distress or any reported instances that might indicate susceptibility to manipulation or exploitation.

 

Negative Statements or Discontent with the Company

  • Trigger Event: HR identifies instances of employees making negative statements about the company, its leadership, or its operations, potentially through personal social media channels, internal communications, or third-party reports. Additionally, such concerns might be raised by managers or colleagues.
  • Indicator: Recorded incidents where employees voice dissatisfaction in forums or interactions that may expose vulnerabilities within the company, which may come from colleagues, managers, or HR’s internal channels.
  • Response: Immediate referral to investigators for further investigation, including tracking if such sentiments are coupled with any increase in risky behaviors (e.g., accessing sensitive data or systems without authorization).

 

Excessive Financial Purchases (Potential Embezzlement or Third-Party Influence)

  • Trigger Event: HR or finance teams notice discrepancies in an employee's personal financial behavior—particularly excessive spending patterns that appear inconsistent with their known salary or financial profile. This could indicate embezzlement, financial mismanagement, or payments from third parties. Such concerns may also be raised by managers or colleagues.
  • Indicator: Transactions that show a high degree of personal spending or financial behavior inconsistent with the employee’s compensation, possibly flagged by HR, finance, or colleagues who notice unusual behaviors.
  • Response: Referral to investigators for correlation with employee access to financial or sensitive company systems, along with further scrutiny of potential illicit financial transactions. Third-party or whistleblower reports, including from colleagues or managers, may also be investigated as part of a broader risk assessment.

 

Hearsay and Indirect Reports

  • Trigger Event: Anonymous or informal reports—such as rumors or gossip circulating in the workplace—that hint at potential insider threat behaviors. These reports, often from colleagues or managers, may be unsubstantiated, but they still warrant an alert if the volume or credibility of the information increases.
  • Indicator: Reports or concerns raised by employees, colleagues, or external parties suggesting that an employee may be engaging in unusual behaviors, such as excessive contact with external vendors, financial irregularities, or internal dissatisfaction.
  • Response: Investigators work with HR to assess the situation by cross-referencing any concerns, including those from colleagues or managers, with the employee's activity patterns, communication, and access to sensitive systems.

 

Implementation Considerations

  • Collaboration Framework: A clear and secure protocol for HR, managers, colleagues, and investigators to share critical information regarding employees at risk. This should maintain employee privacy and legal protections, while still enabling timely alerts.
  • Confidentiality and Privacy: All information related to personal behavior, health, or financial matters must be handled with sensitivity and in accordance with legal and regulatory frameworks, such as GDPR or local privacy laws.
  • Continuous Monitoring: Once flagged, employees should be monitored for any other risk indicators, including changes in data access patterns, unapproved system access, or behavior that correlates with identified risks.

Sections

ID Name Description
MT021Conflicts of Interest

A subject may be motivated by personal, financial, or professional interests that directly conflict with their duties and obligations to the organization. This inherent conflict of interest can lead the subject to engage in actions that compromise the organization’s values, objectives, or legal standing.

 

For instance, a subject who serves as a senior procurement officer at a company may have a financial stake in a vendor company that is bidding for a contract. Despite knowing that the vendor's offer is subpar or overpriced, the subject might influence the decision-making process to favor that vendor, as it directly benefits their personal financial interests. This conflict of interest could lead to awarding the contract in a way that harms the organization, such as incurring higher costs, receiving lower-quality goods or services, or violating anti-corruption regulations.

 

The presence of a conflict of interest can create a situation where the subject makes decisions that intentionally or unintentionally harm the organization, such as promoting anti-competitive actions, distorting market outcomes, or violating regulatory frameworks. While the subject’s actions may be hidden behind professional duties, the conflict itself acts as the driving force behind unethical or illegal behavior. These infringements can have far-reaching consequences, including legal ramifications, financial penalties, and damage to the organization’s reputation.

MT012Coercion

A subject is persuaded against their will to access and exfiltrate or destroy sensitive data, or conduct some other act that harms or undermines the target organization. 

MT017Espionage

A subject carries out covert actions, such as the collection of confidential or classified information, for the strategic advantage of a nation-state.

MT009Fear of Reprisals

A subject accesses and exfiltrates or destroys sensitive data or otherwise contravenes internal policies in an attempt to prevent professional reprisals against them or other persons.

MT011Hubris

A subject accesses and exfiltrates or destroys sensitive data or otherwise contravenes internal policies with the aim to successfully defeat controls in order to demonstrate ability and/or skill.

MT016Human Error

The subject has no threatening motive and is not reckless in their actions. The infringement is a result of an honest mistake made by the subject.

MT020Ideology

A subject is motivated by ideology to access, destroy, or exfiltrate data, or otherwise violate internal policies in pursuit of their ideological goals.

 

Ideology is a structured system of ideas, values, and beliefs that shapes an individual’s understanding of the world and informs their actions. It often encompasses political, economic, and social perspectives, providing a comprehensive and sometimes rigid framework for interpreting events and guiding decision-making.

 

Individuals driven by ideology often perceive their actions as morally justified within the context of their belief system. Unlike those motivated by personal grievances or personal gain, ideological insiders act in service of a cause they deem greater than themselves.

MT001Joiner

A subject joins the organisation with the pre-formed intent to gain access to sensitive data or otherwise contravene internal policies.

MT008Lack of Awareness

A subject is unaware that they are prohibited from accessing and exfiltrating or destroying sensitive data or otherwise contravening internal policies.

MT003Leaver

A subject leaving the organisation with access to sensitive data with the intent to access and exfiltrate sensitive data or otherwise contravene internal policies.

MT013Misapprehension or Delusion

A subject accesses and exfiltrates of destroys sensitive data or otherwise contravenes internal policies as a result of motives not grounded in reality.

MT002Mover

A subject moves within the organisation to a different team with the intent to gain access to sensitive data or to circumvent controls or to otherwise contravene internal policies.

MT004Political or Philosophical Beliefs

A subject is motivated by their political or philosophical beliefs to access and destroy or exfiltrate sensitive data or otherwise contravene internal policies.

MT015Recklessness

The subject does not have a threatening motive. However, the subject under takes actions without due care and attention to the outcome, which causes an infringement.

MT007Resentment

A subject is motivated by resentment towards the organisation to access and exfiltrate or destroy data or otherwise contravene internal policies. 

MT019Rogue Nationalism

A subject, driven by excessive pride in their nation, country, or region, undertakes actions that harm an organization. These actions are self-initiated and conducted unilaterally, without instruction or influence from legitimate authorities within their nation, country, region, or any other third party. The subject often perceives their actions as acts of loyalty or as benefiting their homeland.

 

While the subject may believe they are acting in their nation’s best interest, their actions frequently lack strategic foresight and can result in significant damage to the organization.

MT010Self Sabotage

A subject accesses and exfiltrates or destroys sensitive data or otherwise contravenes internal policies with the aim to be caught and penalised.

MT006Third Party Collusion Motivated by Personal Gain

A subject is recruited by a third party to access and exfiltrate or destroy sensitive data or otherwise contravene internal policies for in exchange for a personal gain.

IF022Data Loss

Data loss refers to the unauthorized, unintentional, or malicious disclosure, exposure, alteration, or destruction of sensitive organizational data caused by the actions of an insider. It encompasses incidents in which critical information—such as intellectual property, regulated personal data, or operationally sensitive content—is compromised due to insider behavior. This behavior may arise from deliberate exfiltration, negligent data handling, policy circumvention, or misuse of access privileges. Data loss can occur through manual actions (e.g., unauthorized file transfers or improper document handling) or through technical vectors (e.g., insecure APIs, misconfigured cloud services, or shadow IT systems).

ME024Access

A subject holds access to both physical and digital assets that can enable insider activity. This includes systems such as databases, cloud platforms, and internal applications, as well as physical environments like secure office spaces, data centers, or research facilities. When a subject has access to sensitive data or systems—especially with broad or elevated privileges—they present an increased risk of unauthorized activity.

 

Subjects in roles with administrative rights, technical responsibilities, or senior authority often have the ability to bypass controls, retrieve restricted information, or operate in areas with limited oversight. Even standard user access, if misused, can facilitate data exfiltration, manipulation, or operational disruption. Weak access controls—such as excessive permissions, lack of segmentation, shared credentials, or infrequent reviews—further compound this risk by enabling subjects to exploit access paths that should otherwise be limited or monitored.

 

Furthermore, subjects with privileged or strategic access may be more likely to be targeted for recruitment by external parties to exploit their position. This can include coercion, bribery, or social engineering designed to turn a trusted insider into an active participant in malicious activities.

IF015Theft

A subject steals an item or items belonging to an organization, such as a corporate laptop or corporate mobile phone.

MT012.004Emotional Vulnerability

A subject’s emotional state is exploited by a malicious third party, particularly during periods of heightened stress, grief, or personal hardship. The third party leverages this vulnerability to manipulate the subject into revealing sensitive information or performing actions that could compromise the organization.

MT012.002Extortion

A third party uses threats or intimidation to demand that a subject divulge information, grant access to devices or systems, or otherwise cause harm or undermine a target organization.

MT012.006Long-Term Relationship Building

A malicious third party gradually builds a relationship with the subject over an extended period, slowly gaining their trust. This trust is then exploited to access sensitive information or systems, often without the knowledge of the subject.

MT012.005Romantic Seduction

A malicious third party employs romantic interest or seduction as a manipulation tactic. Through emotional and psychological engagement, the third party persuades the subject to reveal confidential information, grant access to restricted resources, or carry out actions detrimental to the organization.

MT012.007Sexual Extortion

A subject is extorted by a third party threatening to expose sexual or indecent images connected to them, a tactic commonly referred to as sextortion. These images may be real, obtained by a third party, AI-generated ‘deep fake’ images resembling the subject, or entirely fabricated claims. The extortion is typically financially motivated, which can drive the subject to harm the organization for personal gain. Alternatively, the third party may coerce the subject into compromising the organization by revealing sensitive information or granting unauthorized access.

MT012.001Social Engineering (Inbound)

A third party deceptively manipulates and/or persuades a subject to divulge information, or gain access to devices or systems, or to otherwise cause harm or undermine a target organization.

MT005.003Financial Desperation

A subject facing financial difficulties attempts to resolve their situation by exploiting their access to or knowledge of the organization. This may involve selling access or information to a third party or conspiring with others to cause harm to the organization for financial gain.

MT005.001Speculative Corporate Espionage

A subject covertly collects confidential or classified information, or gains access, with the intent to sell it to a third party private organization.

IF022.004Payment Card Data Leakage

A subject with access to payment environments or transactional data may deliberately or inadvertently leak sensitive payment card information. Payment Card Data Leakage refers to the unauthorized exposure, transmission, or exfiltration of data governed by the Payment Card Industry Data Security Standard (PCI DSS). This includes both Cardholder Data (CHD)—such as the Primary Account Number (PAN), cardholder name, expiration date, and service code—and Sensitive Authentication Data (SAD), which encompasses full track data, card verification values (e.g., CVV2, CVC2, CID), and PIN-related information.

 

Subjects with privileged, technical, or unsupervised access to point-of-sale systems, payment gateways, backend databases, or log repositories may mishandle or deliberately exfiltrate CHD or SAD. In some scenarios, insiders may exploit access to system-level data stores, intercept transactional payloads, or scrape logs that improperly store SAD in violation of PCI DSS mandates. This may include exporting payment data in plaintext, capturing full card data from logs, or replicating data to unmonitored environments for later retrieval.

 

Weak controls, such as the absence of data encryption, improper tokenization of PANs, misconfigured retention policies, or lack of field-level access restrictions, can facilitate misuse by insiders. In some cases, access may be shared or escalated informally, bypassing formal entitlement reviews or just-in-time provisioning protocols. These gaps in security can be manipulated by a subject seeking to leak or profit from payment card data.

 

Insiders may also use legitimate business tools—such as reporting platforms or data exports—to intentionally bypass obfuscation mechanisms or deliver raw payment data to unauthorized recipients. Additionally, compromised service accounts or insider-created backdoors can provide long-term persistence for continued exfiltration of sensitive data.

 

Data loss involving CHD or SAD often trigger mandatory breach disclosures, regulatory scrutiny, and severe financial penalties. They also pose reputational risks, particularly when data loss undermines consumer trust or payment processing agreements. In high-volume environments, even small-scale leaks can result in widespread exposure of customer data and fraud.

IF022.003PHI Leakage (Protected Health Information)

PHI Leakage refers to the unauthorized, accidental, or malicious exposure, disclosure, or loss of Protected Health Information (PHI) by a healthcare provider, health plan, healthcare clearinghouse (collectively, "covered entities"), or their business associates. Under the Health Insurance Portability and Accountability Act (HIPAA) in the United States, PHI is defined as any information that pertains to an individual’s physical or mental health, healthcare services, or payment for those services that can be used to identify the individual. This includes medical records, treatment history, diagnosis, test results, and payment details.

 

HIPAA imposes strict regulations on how PHI must be handled, stored, and transmitted to ensure that individuals' health information remains confidential and secure. The Privacy Rule within HIPAA outlines standards for the protection of PHI, while the Security Rule mandates safeguards for electronic PHI (ePHI), including access controls, encryption, and audit controls. Any unauthorized access, improper sharing, or accidental exposure of PHI constitutes a breach under HIPAA, which can result in significant civil and criminal penalties, depending on the severity and nature of the violation.

 

In addition to HIPAA, other countries have established similar protections for PHI. For example, the General Data Protection Regulation (GDPR) in the European Union protects personal health data as part of its broader data protection laws. Similarly, Canada's Personal Information Protection and Electronic Documents Act (PIPEDA) governs the collection, use, and disclosure of personal health information by private-sector organizations. Australia also has regulations under the Privacy Act 1988 and the Health Records Act 2001, which enforce stringent rules for the handling of health-related personal data.

 

This infringement occurs when an insider—whether maliciously or through negligence—exposes PHI in violation of privacy laws, organizational policies, or security protocols. Such breaches can involve unauthorized access to health records, improper sharing of medical information, or accidental exposure of sensitive health data. These breaches may result in severe legal, financial, and reputational consequences for the healthcare organization, including penalties, lawsuits, and loss of trust.

 

Examples of Infringement:

  • A healthcare worker intentionally accesses a patient's medical records without authorization for personal reasons, such as to obtain information on a celebrity or acquaintance.
  • An employee negligently sends patient health data to the wrong recipient via email, exposing sensitive health information.
  • An insider bypasses security controls to access and exfiltrate medical records for malicious use, such as identity theft or selling PHI on the dark web.
IF022.002PII Leakage (Personally Identifiable Information)

PII (Personally Identifiable Information) leakage refers to the unauthorized disclosure, exposure, or mishandling of information that can be used to identify an individual, such as names, addresses, phone numbers, national identification numbers, financial data, or biometric records. In the context of insider threat, PII leakage may occur through negligence, misconfiguration, policy violations, or malicious intent.

 

Insiders may leak PII by sending unencrypted spreadsheets via email, exporting user records from customer databases, misusing access to HR systems, or storing sensitive personal data in unsecured locations (e.g., shared drives or cloud storage without proper access controls). In some cases, PII may be leaked unintentionally through logs, collaboration platforms, or default settings that fail to mask sensitive fields.

 

The consequences of PII leakage can be severe—impacting individuals through identity theft or financial fraud, and exposing organizations to legal penalties, reputational harm, and regulatory sanctions under frameworks such as GDPR, CCPA, or HIPAA.

 

Examples of Infringement:

  • An employee downloads and shares a list of customer contact details without authorization.
  • PII is inadvertently exposed in error logs or email footers shared externally.
  • HR data containing employee National Insurance or Social Security numbers is copied to a personal cloud storage account.
IF016.001Misuse of a Corporate Card

A subject may misuse a corporate credit for their own benefit by making purchases that are not aligned with the intended purpose of the card or by failing to follow the policies and procedures governing its use.

IF016.006Creation of Fictitious Invoices

A subject with access to a billing system or indirect access to a billing system misuses their access to create fraudulent invoices, causing payments to be diverted to themselves, a business they own, or a third party.

IF016.007Excessive Overtime

A subject that self reports hours worked, and/or is eligible to claim overtime or an individual responsible for reporting such working time may falsify time records or make false representations to a working time system to cause payment or time in lieu for unperformed work.

IF016.004Insider Trading

A subject with access to sensitive or confidential information may decide to use that information to trade the company's stock or other securities (like bonds or stock options) based on significant, nonpublic information about the company.

IF016.005Modification of Invoices

A subject with access to a billing system or indirect access to a billing system misuses their access to modify existing invoices, causing payments to be diverted to themselves, a business they own, or a third party.

IF016.002Unauthorized Bank Transfers

A subject misuses their direct or indirect access to dishonestly redirect funds to an account they control or to a third party.

IF015.004Theft of Non-Digital Assets

A subject steals non-digital assets, such as physical documents, belonging to an organization.

IF015.003Theft of Other Digital Assets

A subject steals other digital assets, such as monitors, hard drives, or peripherals, belonging to an organization.

IF015.002Theft of a Corporate Mobile Phone

A subject steals a corporate mobile phone belonging to an organization.

IF015.001Theft of a Corporate Laptop
