With remote work, hybrid IT environments, and AI-enhanced automation on the rise, insider threats remain among the most damaging and difficult-to-detect risks in cybersecurity. Identifying malicious insider activity may take weeks or even months despite the many efforts companies put into building cybersecurity threat detection systems. You can increase your chances of uncovering malicious activity by studying insider threat techniques and applying diverse detection methods.<\/p>\n\n\n\n

In this article, we discuss what insider threats are<\/a>, the most common techniques behind them, and how to detect and mitigate them.<\/p>\n\n\n\n

Why is early insider threat detection so important?<\/h2>\n\n\n\n

Insider threats<\/a> typically originate from trusted users with access to critical resources who abuse sensitive data or put the organization’s security at risk intentionally or unintentionally. Insider-caused incidents are usually hard to contain: it takes 81 days on average to detect an insider incident, according to the 2025 Cost of Insider Risks Global Report by Ponemon Institute. <\/p>\n\n\n\n

Despite significant advancements in cybersecurity during recent years, detecting insider threats is rather challenging:<\/p>\n\n\n\n

The actions of malicious insiders can cause a great deal of damage if they go unnoticed for a long time. The average cost of handling an insider threat is $17.4 million <\/strong>per organization,\u200b according to the same report by Ponemon Institute. The report also highlights how malicious insiders cause incidents that result in higher per-case costs, whereas negligent and outsmarted insiders account for 75% of total insider-related incidents. Employees who ignore policies, utilize shadow IT<\/a>, or mishandle devices may unintentionally open the door to serious breaches. <\/p>\n\n\n\n

We\u2019ve previously discussed several examples of insider threats<\/a> that demonstrate how the consequences can be far more severe than the obvious financial issues. For instance, in 2024, a former Google engineer openly leaked proprietary Pixel chip designs<\/a> on social media, exposing Google’s trade secrets to the world. The ex-employee even tagged Google rivals Apple and Qualcomm in his posts and boasted he’d do “unethical” things to get what he felt he was owed\u200b. As a result, Google had to scrap the exposed chip schematics, which significantly impacted the company\u2019s competitive advantage.<\/p>\n\n\n\n

Another high-impact insider-related incident occurred at MedStar Health in 2024<\/a> when employee negligence allowed an external attacker to access and expose the personal data of over 183,000 patients. The breach lasted nearly nine months and was attributed to phishing attacks on three employees\u2019 email accounts, as well as poor oversight of employee access privileges. While financial penalties were not publicly disclosed, the reputational damage and regulatory scrutiny following the event highlighted how human error and inadequate access controls continue to expose central vulnerabilities in cybersecurity.<\/p>\n\n\n\n

In the above examples, each organization suffered from preventable cybersecurity incidents that were preceded by different insider threats. Let\u2019s take a closer look at some of the most common malicious insider techniques in the next section.<\/p>\n\n\n\n

Key insider threat techniques <\/h2>\n\n\n\n

The way a cyberattack is executed can be referred to as a technique, tactic, process, or method. For the sake of clarity, this article uses MITRE\u2019s definition<\/a> of an attack technique:<\/p>\n\n\n\n

The technique behind an insider threat usually depends on an attacker\u2019s intent, level of technical skills, knowledge of the organization\u2019s security system, and their access level.<\/p>\n\n\n\n

According to MITRE\u2019s Enterprise ATT&CK matrix, as laid out in their knowledge base<\/a>, the malicious insider common techniques include:<\/p>\n\n\n\n
