Why Waiting for Alerts Isn’t Enough

Many businesses rely on alerts to know when something’s wrong. But by the time an alert goes off, the damage could already be happening. Proactive threat hunting is a different approach—it’s about going on the offensive, actively seeking out potential threats within your systems before they trigger an alert or cause harm. At DeepTide, we believe that proactive threat hunting is essential for any company that wants to stay ahead of sophisticated cyber threats. Let’s explore what proactive threat hunting is, why it matters, and how it can keep your business more secure.

What Is Proactive Threat Hunting?

Proactive threat hunting is a cybersecurity practice that involves actively searching for threats within your network. Rather than waiting for automated systems to detect unusual activity, skilled security professionals dive into your network, looking for signs of compromise, abnormal behavior, and potential vulnerabilities. Threat hunting is a process that combines knowledge of emerging attack patterns, in-depth data analysis, and a thorough understanding of your network’s normal behavior.

Unlike traditional monitoring, which waits for suspicious activities to pop up, threat hunting seeks out threats that might be quietly lurking, potentially avoiding detection. By proactively hunting for threats, you can catch advanced attackers who know how to bypass standard defenses.

Why Alerts Alone Aren’t Enough

Many companies rely solely on alerts from their security tools to respond to potential threats. But here’s why that can be a dangerous approach:

1. Delayed Detection: Alerts are often reactive, meaning they signal that something bad is already happening. By the time the alert goes off, an attacker might already have accessed critical data or moved laterally across your network.
2. Alert Fatigue: Security teams receive countless alerts every day, many of which are false positives. It’s easy for real threats to slip through in the noise, especially if your team is stretched thin.
3. Advanced Threats Avoid Detection: Sophisticated attackers know how to hide their tracks, sometimes slipping through traditional detection systems. They may use techniques like fileless malware, living-off-the-land attacks, or encrypted communication to avoid triggering alerts.
4. Zero-Day Vulnerabilities: Automated defenses may not be equipped to detect zero-day attacks—threats exploiting unknown vulnerabilities. Threat hunting can help identify unusual behavior that might signal these types of attacks, even if the exact exploit isn’t known.

How Proactive Threat Hunting Works

Threat hunting usually involves three main steps:

1. Hypothesis Creation: The threat-hunting team starts with a hypothesis based on known attack methods, industry trends, or specific risks within your organization. For instance, they might suspect a particular type of phishing campaign is targeting employees.
2. Data Collection and Analysis: The team then collects data from across your network, including logs, traffic patterns, and system events. They analyze this data, looking for signs that support or disprove the hypothesis.
3. Investigation and Response: If the team uncovers suspicious activity, they dig deeper to determine whether it’s a real threat. If confirmed, they move to contain and neutralize the threat, often before it causes significant harm.

Benefits of Proactive Threat Hunting

1. Catch Stealthy Attacks Early: Many advanced attackers know how to avoid standard detection tools. Threat hunting gives you a way to catch these attackers in the act, before they have a chance to do serious damage.
2. Reduce Dwell Time: Dwell time is the period an attacker spends inside your network undetected. The longer they’re in, the more damage they can do. Threat hunting helps reduce dwell time by catching intrusions early.
3. Better Incident Response: When you find and address threats early, your response time is faster and more effective. Threat hunting improves your incident response capabilities by catching attacks at the earliest stage.
4. Enhanced Security Posture: Regular threat hunting helps keep your defenses sharp, identifying areas where you can strengthen your security. It’s an ongoing learning process that makes your organization more resilient over time.
5. Improved Understanding of Normal Activity: By constantly looking at patterns and behaviors in your network, threat hunters gain a deep understanding of what “normal” looks like. This makes it easier to spot anything unusual.

Real-World Example: How Threat Hunting Can Prevent a Breach

Imagine a healthcare organization that’s worried about a new type of phishing attack targeting hospitals. They start a threat-hunting mission with the hypothesis that attackers may be trying to access sensitive patient records by targeting remote workers.

The threat-hunting team looks for any unusual logins or access patterns. They discover that a few accounts are behaving oddly, logging in from unusual IP addresses and accessing files outside of their typical work hours. Digging deeper, they confirm that the logins are unauthorized, and they identify the attackers before they can exfiltrate sensitive data.

In this case, proactive threat hunting allowed the healthcare organization to prevent a breach before it even started, protecting both their data and their reputation.
