Insider Threat Incidents and What They Can Teach Us

Insider threats are not just a theoretical risk; they represent a significant danger that can have real and damaging consequences. These threats are more common than many realize and have even impacted some of the world's largest companies. 


In this article, we’ll cover the primary causes of insider threats and explore real-life examples of incidents that have occurred. By examining past incidents, we can gain valuable insights and adapt our security strategies to better safeguard against these risks.


What Are Insider Threats?


Insider threats occur when individuals within an organization—such as employees, contractors, or business partners—intentionally or unintentionally cause harm. These threats can manifest in various ways, from data theft to physical violence, and can be driven by motives like financial gain, revenge, or even simple negligence.


Detecting insider threats can be particularly difficult, since they originate from trusted individuals within the organization who often have legitimate access to sensitive systems. It is important to understand the main causes of insider threats to effectively respond to and mitigate emerging risks.


What Are the Main Causes of Insider Threats?


There are many different types of insiders and threats that they can cause, making it difficult to build a comprehensive response. Some of the main causes for insider threats are:


  • Departing Employees: When employees leave an organization, they might take sensitive information with them, either out of spite or to gain an advantage at their new job.

  • Social Engineering: This involves manipulative tactics that deceive employees into revealing confidential information, often by posing as trusted figures within the company.

  • Phishing: Cybercriminals use deceptive emails to trick employees into providing login credentials or personal information, compromising the organization's security.

  • Deepfake Technology: Advanced synthetic media techniques are used to create highly realistic but fake audio or video recordings, often impersonating someone else convincingly to deceive employees.

  • Theft: This involves the stealing of proprietary data or physical assets from the organization, typically for personal gain or to benefit a competitor.

  • Sabotage: Intentional actions taken by insiders to damage or disrupt company operations, usually motivated by revenge or financial gain.

  • Disgruntled Employees: This category represents individuals within the organization who harbor grievances or dissatisfaction, which can escalate into harmful actions such as workplace violence.


Understanding these diverse factors sets the stage for learning from specific real-world incidents.


Real-World Examples of Insider Threat Incidents 


Companies of all sizes—and in locations around the world—have been affected by insider threats. These three incidents showcase the damaging consequences that can occur when adequate safeguards and protections are not taken.


1. Employee Sends $25M To Scammers Due To Deepfake


Incident Overview 

One employee at an unnamed company this year fell victim to a sophisticated scam involving a deepfake video conference. The scammers used advanced technology to create a realistic imitation of a high-ranking executive. During the video call, the fake executive convinced an unsuspecting employee that an urgent transfer of $25 million was necessary.


The employee, believing they were speaking with a legitimate authority figure, proceeded to arrange the transfer without suspecting any foul play. It was only after the funds had been transferred that the company realized they had been deceived by a deepfake.


Impact and Repercussions  

The financial loss was substantial, and the incident also damaged the company’s reputation. Trust within the organization was shaken, exposing vulnerabilities in their verification processes. Moreover, the company had to invest significant resources into investigating the incident and enhancing their security protocols to prevent future occurrences.


Causes and Preventive Measures  

The scam succeeded due to the convincing nature of the deepfake technology and the lack of established verification procedures. To prevent such incidents, companies should implement multi-factor authentication and train employees to verify identities through multiple channels before authorizing significant transactions. Regular training on recognizing and responding to social engineering tactics is also essential.


2. Security Breach at Tesla: Former Employees Leak Sensitive Data to Foreign Media


Incident Overview 

In 2023, former Tesla employees leaked thousands of personal records to a German news outlet. These records included sensitive information of over 75,000 employees, such as contact details, employment history, and other personal data. The leak occurred after the employees had left Tesla, taking the data with them as they departed the company.


The news outlet published parts of the leaked data, drawing public attention and scrutiny. This incident raised serious concerns about Tesla's data protection measures and their ability to safeguard personal information.


Impact and Repercussions  

Tesla faced severe repercussions, including potential legal action, loss of employee trust, and damage to its public image. The incident also highlighted the need for stringent data protection measures. Some employees became wary of the company's ability to protect their personal information, leading to decreased morale and trust within the organization.


Causes and Preventive Measures  

This breach occurred due to insufficient data access controls and monitoring. To prevent such leaks, organizations must enforce strict data access policies and conduct regular audits to detect any unauthorized access or data transfers. Implementing strong data encryption and ensuring departing employees return all company devices and data can also mitigate such risks.


3. Yahoo’s Insider Breach From A Malicious Employee


Incident Overview  

In February of 2022, a former Yahoo employee allegedly stole trade secrets upon receiving a job offer from The Trade Desk, one of its competitors. The individual took over 570,000 pages of proprietary information that could provide a competitive advantage to their new employer, including confidential business strategies, product development plans, and other sensitive data.


The theft was discovered when Yahoo conducted an internal investigation, revealing that the departing employee had accessed and transferred large amounts of sensitive information shortly before leaving the company.


Impact and Repercussions  

Yahoo faced legal challenges and potential financial losses due to the theft of valuable intellectual property. The incident showcased the risk of trade secret theft during employee transitions. This situation necessitated a costly legal battle to recover the stolen data and mitigate the competitive advantage gained by the new employer.


Causes and Preventive Measures  

The theft happened because of inadequate exit protocols and insufficient monitoring of departing employees. Companies should implement rigorous offboarding processes and monitor the activities of employees who are leaving to ensure sensitive information is not taken. Additionally, legal agreements such as non-compete and confidentiality clauses can provide further protection against such thefts.
