In today’s digital landscape, security breaches are a constant threat. The best defense? Proactive threat hunting. But sifting through mountains of data can be overwhelming. This article unveils five battle-tested techniques to sharpen your company’s threat awareness and fortify your defenses.
1. Target Your Region, Narrow Your Focus
Understanding the threats targeting businesses in your region offers a powerful advantage. Attackers often launch mass campaigns, making it likely you’ll face similar threats. This allows for early detection and proactive adjustments.

ANY.RUN boasts a massive public database of security
“`
threatName:phishing AND submissionCountry:de NOT taskType:url
“`
TI Lookup displays a list of public sandbox sessions containing phishing documents, emails, and more. Each session offers a deep dive into the attack, revealing attacker tactics and network activity. Analyze these sessions to gain invaluable intel and prepare your defenses.
2. Verify Suspicious Activity with TI Tools
Security teams face a constant barrage of alerts. Unfortunately, not all get investigated thoroughly, creating a vulnerability. But verifying suspicious system and network artifacts with TI tools can save your organization from significant losses.
Example: Security professionals might encounter an unusual IP connection. Verifying this IP with TI Lookup can expose its malicious nature and provide context, such as the threat name (e.g., Agent Tesla) and associated sandbox sessions. The same applies to suspicious scripts. You can query for specific script formats in certain directories, like:
“`
commandLine:C:\Users\Public\.ps1 OR commandLine:C:\Users\Public\.vbs
“`
TI Lookup returns a list of matching scripts found across various sandbox sessions, allowing further analysis and preventive measures.
3. Go Beyond Indicators: Understand Attacker Tactics
While blocking known indicators of compromise (IOCs) is important, they often change quickly. A more sustainable approach is to understand the tactics, techniques, and procedures (TTPs) attackers use in your industry.
How TI Lookup Empowers You:
TI Lookup offers an actionable MITRE ATT&CK matrix, a framework detailing attacker behaviors. It includes real-world malware and phishing threats demonstrating these TTPs in action. This allows you to explore attack methods, identify threats using specific TTPs, and develop targeted countermeasures against emerging threats.
4. Stay Ahead of Evolving Threats
Threats mutate and adapt as organizations adjust their defenses. Keeping track of once-threatening adversaries is crucial to mitigate emerging threats and prepare for future attacks.
TI Lookup to the Rescue:
TI Lookup allows subscribing to notifications about updates on specific threats, indicators, and combinations of data points. For instance, you can subscribe to receive information on new Lumma Stealer domains and network activities:
“`
threatName:lumma AND domainName:
“`
This ensures
5. Leverage Third-Party Reports for Deeper Insights
Security reports offer valuable intel on potential threats. But the information can be limited. Fortunately, TI Lookup allows you to enrich this data with your own research.
Example: Imagine a report on malware targeting manufacturing companies. You can use TI Lookup to find additional samples related to the campaign by combining threat names with specific files used by attackers, like:
“`
filePath:dbghelp.dll AND threatName:lumma
“`
This query reveals dozens of matching sandbox sessions, significantly enriching the report data and informing your defenses against these attacks.
By implementing these five techniques and leveraging TI Lookup, your organization can significantly improve its threat hunting capabilities, proactively identify and mitigate threats, and fortify its security posture.
