Proactive Threat Detection to Stay Ahead of Cyber Adversaries

At Sparrow Strategies, our Threat Hunting services focus on proactive detection, searching for hidden threats that evade traditional security solutions. Unlike reactive measures that respond after an alert, threat hunting identifies adversaries before they cause significant harm.

Our approach combines human expertise, advanced analytics, and leading-edge technology to uncover sophisticated attacks that often bypass automated security controls. By utilizing behavior analytics and attack surface analysis, we help clients mitigate risks proactively.

Our Approach to Threat Hunting:

  • Hypothesis-Driven Exploration: We start with a hypothesis based on the latest threat intelligence and looking for patterns and behaviors associated with known attack vectors.

  • Data Analysis and Correlation: We comb through security logs, network traffic, endpoint behavior, and other sources to identify anomalies.

  • Investigative Techniques: Utilizing tools and manual techniques, our experts dig deep into suspicious activity, mapping it to known tactics, techniques, and procedures (TTPs) associated with threat actors.

  • Continuous Improvement: Every threat hunt contributes to improving defenses, as we analyze findings to identify trends and make our clients' environments more resilient against future threats.

Key Tools and Techniques Used:

SIEM (Security Information and Event Management) Tools

Splunk Splunk's search and correlation capabilities allow us to comb through massive data sets, quickly identifying abnormal patterns.

Elastic Stack (ELK) ElasticSearch, Logstash, and Kibana are used to ingest, visualize, and correlate data for deep threat analysis.

Endpoint Detection and Response (EDR)

CrowdStrike Falcon and Carbon Black We use EDR solutions to monitor endpoint activity for suspicious behavior and potential compromises.

Network Traffic Analysis

Wireshark For packet-level analysis and deep dive into traffic flows.

Zeek (Bro) This powerful network monitoring tool helps us identify unusual traffic patterns that might signify a threat.

Threat Intelligence Platforms

MISP (Malware Information Sharing Platform) and ThreatConnect These are used to correlate gathered information with known threat actor activities, adding context to suspicious indicators.

MITRE ATT&CK Framework

We use the MITRE ATT&CK framework to map observed activities to known adversary tactics, techniques, and procedures. This helps us understand the potential attack paths and behaviors.

Behavioral Analytics and Machine Learning

Splunk User Behavior Analytics (UBA) and Elastic's Machine Learning Tools These are used to identify anomalies that could indicate suspicious behavior, especially for detecting insider threats.

Poractive Defense

Detecting threats before they escalate minimizes the potential for widespread impact.

Detailed Attack Analysis

Uncovering the nature and tactics of hidden adversaries helps strengthen defenses.

Tailored Insights

Findings from our threat hunts help organizations develop targeted defense improvements specific to their environments.
