Threat Hunting: 5 Game-Changing Strategies to Stay Ahead

In the ever-evolving world of cybersecurity, staying one step ahead of attackers can make all the difference between a close call and a devastating breach. The most effective defense lies in proactive threat hunting—identifying risks before they strike. However, with the overwhelming flood of data available, even experienced security teams can struggle to extract actionable intelligence. To cut through the noise and elevate your threat-hunting game, here are five proven strategies that will enhance your organization’s ability to detect and neutralize cyber threats.

1. Learn from Threats Targeting Local Organizations

The easiest way to understand the threat landscape specific to your organization is by studying the attacks other businesses in your region are experiencing. Cybercriminals often target multiple companies within the same geographic area as part of larger campaigns, creating opportunities to preemptively strengthen your defenses.

Why it works:

• Fine-tunes your defensive strategy.
• Ensures better prioritization of threats.
• Optimizes resources for maximum impact.

How to do it:
Platforms like ANY.RUN provide an extensive public database filled with malware and phishing samples uploaded by over 500,000 security professionals globally. Using its Threat Intelligence (TI) Lookup, you can search for threats by geographic location, type, or other parameters. For example, to find phishing threats in Germany, use a query like:

threatName:"phishing" AND submissionCountry:"de" NOT taskType:"url"

This query filters out URLs to focus on malicious files, providing detailed insights into the attacks targeting your region. By exploring sandbox sessions, you can gain a deeper understanding of these threats, including their behavior and potential impact.

2. Verify Suspicious Activity with Threat Hunting Intelligence Tools

Mid-sized security teams often face hundreds of alerts daily, many of which go unchecked. This leaves a dangerous gap for cybercriminals to exploit. Verifying suspicious artifacts through TI tools can help prevent these oversights and safeguard your organization against costly attacks.

Why it works:

• Detects malicious activities early.
• Offers insight into attacker techniques.
• Enables faster incident response.

How to do it:
For instance, unusual IP connections can easily be overlooked. Using TI Lookup, security teams can verify these IPs for malicious activity. A query like:

destinationIP:"78[.]110[.]166[.]82"

instantly identifies threats, providing context such as the malware name (e.g., Agent Tesla) and related sandbox sessions. Similarly, you can use queries to analyze suspicious scripts. For example:

commandLine:"C:\\Users\\Public\\*.ps1" OR commandLine:"C:\\Users\\Public\\*.vbs"

This query finds scripts in .ps1 and .vbs formats located in the Public directory, revealing critical data about potentially harmful activities.

3. Track Threat Hunting by Tactics and Techniques

Attackers frequently change their indicators of compromise (IOCs), but their underlying tactics, techniques, and procedures (TTPs) remain consistent. Tracking these TTPs offers a more sustainable approach to threat hunting.

Why it works:

• Provides detailed insights into attacker methods.
• Aids in crafting specific countermeasures.
• Strengthens defenses against emerging threats.

How to do it:
ANY.RUN’s TI Lookup offers an actionable MITRE ATT&CK matrix that maps TTPs used in malware and phishing campaigns. For example, exploring technique T1562.001 (used to disable security tools) reveals related attack signatures and sandbox reports. These insights allow you to build robust defenses against similar threats.

4. Stay Updated on Evolving Threats

Threats constantly adapt as organizations improve their defenses. Tracking these changes ensures your security measures remain effective.

Why it works:

• Enables timely mitigation of new threats.
• Improves situational awareness.
• Prepares your team for evolving attack patterns.

How to do it:
TI Lookup lets you subscribe to updates on specific threats or indicators. For instance, to monitor developments in the Lumma Stealer malware campaign, you can set up a query like:

threatName:"lumma" AND domainName:""

This subscription alerts you to new IOCs or behaviors related to Lumma, helping your team stay ahead of attackers.

5. Enhance Threat Reports with Deeper Analysis

Third-party threat reports provide valuable insights but are often incomplete. Conducting your own research can uncover additional details, giving you a more comprehensive understanding of the threats.

Why it works:

• Fills gaps in existing threat intelligence.
• Validates data for accuracy.
• Supports informed decision-making.

How to do it:
Consider a report on an attack using Lumma and Amadey malware targeting manufacturing firms. By combining known details (e.g., malware name and file path) in a query like:

filePath:"dbghelp.dll" AND threatName:"lumma"

you can uncover related sandbox sessions, enriching the original report and informing stronger defenses.

Conclusion: Supercharge Your Threat Hunting with ANY.RUN

ANY.RUN’s Threat Intelligence Lookup is a powerful ally for modern security teams, offering:
