Don’t Be the Easy Target

The threat landscape is always changing so when it comes to developing, implementing, and operationalizing new detections for emerging threats, the job is never done.

Today’s threat actors operate like businesses, executing deliberate strategies, backed by tremendous resources and a commitment to investing in continuous R&D that makes it almost impossible for most security teams to keep up. These groups have experts spearheading various tasks like developing zero-day exploits, gaining initial access into an organization’s environment, launching lucrative ransomware attacks, and money laundering.

You need a security program that includes timely threat intelligence that fuels your real-time threat detection and response, and proactive threat hunting.

Building an Effective Threat Hunting Program

Once cyber threat intelligence is gathered threat hunters can conduct threat hunts to search for signs of early threat actor targeting behaviors, malicious activities or indicators of compromise (IOCs) before threat actors establish a deeper presence within your organization’s environment. This process involves monitoring both attacker behaviors such as evidence of lateral movement, privilege escalation attempts, and anomalous user activity, as well as indicators like the presence of malware artifacts, unusual network traffic, and command & control mechanisms.

An effective threat hunting program carries three primary objectives:

1
Identify unknown threats and vulnerabilities before they can inflict significant damage.
2
Enhance your security posture by integrating the insights gained from proactive global threat hunts into a wider cybersecurity strategy.
3
Reduce the mean time to detect (MTTD) and the mean time to respond (MTTR) to cyber threats so you can minimize their potential impact.

Your threat hunts will dictate if a new detection should be built based on the information collected. Once a new detection and runbook are developed, the Elite Threat Hunters proceed to the next unknown threat, repeating the entire process.

Our Superpower:
Cyber Threat Intelligence

eSentire’s Threat Response Unit (TRU) is an industry-leading team of threat hunters and researchers committed to building threat detection models across the eSentire XDR Cloud Platform and supporting our 24/7 Security Operations Centers (SOCs) to stop threats before they disrupt your business. In fact, eSentire TRU has discovered some of the most dangerous threats and nation-state attacks in our space. We broke the news on the Kaseya MSP breach, the malicious more_eggs malware and more.

TRU collects and processes cyber threat intelligence from 54 commercial threat feeds and 10+ proprietary intel sources, the Dark Web, social media, security reports, positive SOC-driven threat investigations, and various third-party tools to conduct further investigations and identify potential Indicators of Compromise (IOCs).

TRU works as an extension of your security team to continuously improve our Managed Detection and Response (MDR) service so you can rest easy knowing that you’re protected by an MDR provider that law enforcement agencies rely on to identify threat actors and collaborate on cyber threat intelligence.

Cyber Threat Intelligence FAQ

What is cyber threat intelligence?

Cyber threat intelligence is gathered information and data about potential cyber attackers moves, from both public and private sources and trusted partners. This information is used by a cyber threat hunting team either manually or with automation tools to identify possible threats in your environment.

What is a threat intelligence feed?

A cyber threat intelligence feed is a continuous stream of data providing information about potential and current cyber threats. It can be used to identify, understand, and possibly prevent cyber threats, while improving your organization's overall security posture.

What is proactive threat hunting?

Cyber threat hunting is a proactive method used to find hidden threats within your organization’s environment. It involves using tools and techniques to investigate potential incidents, identify malicious activity, and track down the threat actors behind it.

How is cyber threat intelligence used in Managed Detection and Response (MDR)?

MDR leverages cyber threat intelligence to help you build a more resilient security program through:

Early threat identification and real-time information about new and emerging threats
Triage and analysis of true positives based on known threat behaviors, actors, and indicators
Leveraging threat intelligence on the nature and motive of attacks to create an effective threat response strategy
Proactive defense by understanding vulnerabilities and likely attack types
Reduction of attack surface by eliminating vulnerabilities

What cyber threat intelligence resources do you have available?

eSentire’s TRU team regularly publishes security advisories, malware analyses, TRU Positive blogs, reports, industry publications, and webinars based on insights from their original research and proactive threat hunts.
