Have my network and information systems been compromised? If so, how severe is the incident?
How did the attackers gain entry, and what did they do?
How can I stop similar attacks in the future?
What can I improve the effectiveness of my threat hunting activities?
Threat Hunting is a focused, iterative, proactive investigation to searching out, identifying, and understanding adversaries internal to the client’s networks. It is an intelligence-led and expert-driven approach that looks for evidence that a compromise may have occurred within your organization, whether successful or not.
Threat actors are continually enhancing their techniques to exploit the latest detection tools and controls. Proactive threat hunting becomes possibly the most critical factor. We aim to outsmart the attackers, utilizing our vast experience and investigative techniques to discover indications of a breach.
An Active Threat Hunting is a mix of in-depth expertise of your environment and the capacity to understand the details of the changes that are taking place in your environment. Security teams need to study their system, understand their users and use tools that give them the insight to differentiate between good and evil. The attacker must perform extensive recon to discover weak targets to exploit.
When executing a penetration test, you’re effectively attempting to go around the organization’s defenses to realize what systems an attacker could access and perceive how far the adversary could progress in your environment. You’re attempting to penetrate your defenses from outside the perimeter.
Threat Hunting is more of an inside-out approach where the assumption is that the threat actors are already present in your environment, regardless of your best efforts to keep them out. Looking at what’s happing inside of your environment, particularly odd behavior will lead to discovering malicious activity.
Our experienced research consultants at Krash act as the intelligent hunter that will search for malicious actors and evidence of a compromise and afterward investigate anything that is of concern, which includes researching sources both inside and outside your network perimeter and across all phases of intrusion and exploitation.
During a risk assessment, we will assemble and dissect data and intelligence from a variety of open and privileged sources to profile the relevant cyber adversaries, their aims, capacities, objectives, and procedures they could use against your organization.
TOOLS OF A THREAT HUNTER
Data. It should include logs from all your network devices, including servers, firewalls, databases, routers, switches, etc., along with all endpoints. It is crucial to have a central location to accumulate the data for analysis. It should also include the process to aggregate, correlate, and normalize the millions of data points you have collected.
The baseline of the environment. For a better understanding of your network’s behavior, it is recommended to baseline it over time. If you can confirm the events in the baseline as expected, then you can spend less time looking at the false positives, and more time looking at the events that do not fit your baseline.
Threat Intelligence. With cyber-attacks increasing, the likelihood for many organizations to experience the same attack also increases. When such an incident occurs, the information gathered keeps you updated on the current threat environment enabling you to understand and effectively respond to evolving threats quickly.
- Reducing of time from infection to detection.
- Preventing the spread of infection or lateral movement through the network
- Reduction in the number of actual breaches based on the number of incidents detected
- Reducing the exposure to external threats
- Reduction of time and money spent on response.
At Krash Consulting, we understand the attacker’s mindset from being a leading provider of penetration testing services, where our goal is to mimic the sophisticated tactics and tools used by malicious actors to help clients keep their network secure from breaches.
