Ransomware Insider Threats: Understanding the Growing Danger

Understanding the Risks of Ransomware Insider Threats

The trope of the burglar comparison in cybersecurity is more than overused. But when we talk about the damage of a break-in, it’s not just picking the lock that’s the problem—we worry about the consequences of ransomware insider threats: what attackers can steal, destroy, or even plant. And yes, I have an active imagination.

Ransomware comes in different shapes and sizes. Whether it originates from nation-states, competitive attack tactics, or organized crime, ransomware insider threats are a booming part of the business. According to the White House National Cybersecurity Strategy, ransomware remains one of the most persistent and disruptive threats globally. Attackers face low risk of being caught while enjoying high rewards.

The Threat Comes from Within

Every cybersecurity professional knows the risk ransomware poses to their organization. To mitigate it, they stack their networks with cutting-edge technologies designed to protect customer data and business continuity. But what happens when the threat comes from inside the house?

The latest tactic adopted by ransomware groups involves insider threats—recruiting employees themselves. Why break in when someone can prop the door open for you? Social engineering makes this even easier, equipping attackers with lists of potential accomplices.

An Inside Job

In 2023, Abnormal Security documented an attempt where attackers tried to recruit an insider, shedding light on how ransomware insider threats unfold. By pretending to play along, they uncovered telling details:

• The attacker wasn’t particularly tech-savvy but had access to ransomware strains that could extort victims.
• Initial attempts involved classic phishing schemes aimed at high-level executives, scraped from LinkedIn.
• The attachment used was a well-known ransomware variant, readily accessible online.

With groups like LockBit’s Ransomware-as-a-Service (RaaS) and DemonWare’s code available on GitHub, reaching out to insiders has become an attractive strategy for attackers. This approach simplifies their operations and bypasses traditional access controls.

How to Defend Against Ransomware Insider Threats

According to Gartner’s Top Cybersecurity Trends for 2024, continuous threat exposure management programs are essential for building resilience against evolving cyber threats. Despite implementing robust zero-trust and least-privilege policies, the risk of insider threats remains.

What if an employee decides to deploy ransomware? How can you detect it before it’s too late?

The answer lies in testing—again and again. Not just simulations, but real tests using actual ransomware strains and exploitation techniques.

Automated Security Validation: The Call of the Hour

Organizations need full visibility into their networks to reduce cyber exposure and make informed decisions about where to focus remediation efforts. Automated security validation provides this visibility by continuously testing defenses against real-world threats, including ransomware insider threats.

To truly mitigate ransomware risks, validation must occur as often as needed—not annually, not quarterly, but on demand. Testing ensures organizations stay one step ahead, shifting from being ransomware aware to becoming RansomwareReady™.

The Path to RansomwareReady™

The key to defending against ransomware threats lies in a cycle of validation, remediation, and repetition. Security teams equipped with actionable insights can confidently address vulnerabilities and strengthen their resilience to insider and external threats alike.

Make the switch from pondering potential payouts to feeling confident in your defenses. Validate, remediate, repeat—and stay ahead of the ransomware curve.
