A first look at threat intelligence and threat hunting tools

April 17, 2022

A review of several of one of the most preferred open-source devices for risk knowledge and also risk searching

As the term risk knowledge can be conveniently confused with risk searching, we will certainly initially venture to describe several of the distinctions in between them.

Hazard knowledge describes the gathering and also enrichment of information to produce a well-known account of what a particular cyberattack, destructive project, or assailant’s capacity resemble.

Hazard searching, on the other hand, describes the procedure of examining occasion information for unusual and also destructive habits in a network that might suggest the breach of an assailant, the burglary of information, or various other damages. Although risk knowledge does not have the very same goals as risk searching, it acts as a superb factor of separation for risk searching.

Currently allow’s consider an option of open-source devices made use of in both techniques:

Number 1. 7 preferred open-source devices for risk knowledge and also risk searching

Hazard knowledge devices


Your everyday threat intelligence (Yeti) is a system birthed from the requirement of protection experts to streamline several risk information feeds. Experts often manage concerns such as: “Where was this indication observed?” and also “Is this details pertaining to a particular assault or malware household?” To address these concerns, Yeti aids experts to arrange Indicators of Concession (IoCs) and also details on the techniques, strategies, and also treatments (TTPs) used by aggressors in a solitary, unified database. As soon as consumed, Yeti immediately enhances the signs, as an example, by solving domain names or geolocating IP addresses.

Number 2. Detailing observables in Yeti

Number 3. Tracking destructive projects in Yeti

Yeti attracts attention for its capacity to consume information (also blogposts), improve them, and afterwards export the enriched information to various other devices made use of in a company’s risk knowledge community. This enables experts to concentrate on utilizing this device to accumulated risk details rather than bothering with just how to import and also export information in a machine-readable layout. The enriched information can after that be shown various other systems for case administration, malware evaluation, or tracking.

To additionally enhance the operations of experts, Yeti likewise supplies an HTTP API with accessibility fully power of the device both from a command covering and also from various other risk knowledge devices.


MISP, Open Resource Hazard Knowledge and also Sharing System (previously called Malware Info Sharing System), is a cost-free device for sharing IoCs and also susceptability details in between companies, hence advertising joint deal with risk knowledge. The system is made use of by companies around the globe to develop relied on communities that share information so regarding associate it and also accomplish a far better understanding of hazards targeting certain industries or locations.

Number 4. MISP control panel

Rather than sending out IoCs by means of e-mail and also as PDF files, the system aids working together companies much better handle just how details is shared and also streamlined in between them. The details cooperated MISP neighborhoods can after that be fed right into Yeti for additional enrichment.


Comparable to Yeti, Open Cyber Threat Intelligence (OpenCTI) is a system for consuming and also accumulating information so regarding improve a company’s expertise regarding hazards. It is sustained by France’s nationwide cybersecurity firm ANSSI, the Computer System Emergency Situation Action Group for the EU (CERT-EU), and also Luatix.

Along with by hand going into risk information, OpenCTI deals connectors to immediately consume risk information feeds and also details from preferred risk knowledge resources, consisting of MISP, MITRE ATT&CK, and also VirusTotal. Various other ports are readily available to improve information with resources like Shodan and also export information right into systems like Elastic and also Splunk.

Number 5. OpenCTI control panel


Harpoon is a command line device that features a collection of Python plugins to automate open-source knowledge jobs. Each plugin supplies a command that experts can utilize to seek advice from systems such as MISP, Shodan, VirusTotal, and also Have I Been Pwned, by means of their APIs. Experts can utilize greater degree commands to collect details pertaining to an IP address or domain name from all these systems simultaneously. Ultimately, various other commands can inquire link shortener solutions and also search social media sites systems, GitHub databases, and also internet caches.

Number 6. Harpoon running in a command covering

Hazard searching devices


Although it is closed resource, System Monitor (Sysmon) is a cost-free Windows device that keeps track of and also logs tasks such as procedure productions, network links, loading of chauffeurs and also DLLs, and also adjustments of documents production timestamps to the Windows Occasion Log. As Sysmon does not assess system information, risk seekers usually utilize a Protection Info and also Occasion Monitoring (SIEM) device to gather and also assess the information logged by Sysmon for questionable and also destructive tasks occurring in the network.


Because SIEM remedies need a paid certificate, a cost-free choice isAPT-Hunter Launched in 2021, APT-Hunter is an open resource device that can assess the Windows Occasion Log to find hazards and also questionable tasks. The device presently has a collection of greater than 200 discovery guidelines to recognize destructive task such as pass-the-hash and also password splashing strikes, along with various other questionable task for hands-on examination by risk seekers. Most of the guidelines map straight to the MITRE ATT&CK data base.

APT-Hunter can gather Windows visit both the EVTX and also CSV layouts. Upon implementation, APT-Hunter creates 2 result documents:

  • A.xlsx documents which contains all occasions discovered as questionable or destructive.
  • A.csv documents that can be filled right into Timesketch to present the development of a strike chronologically.


DeepBlueCLI is an open resource device given in the SANS Blue Group GitHub database that can assess EVTX documents from the Windows Occasion Log. The device analyzes logged Command covering and also PowerShell command lines to recognize questionable signs like lengthy command lines, regex searches, obfuscation, and also anonymous Ex-spouses and also DLLs; strikes on individual accounts like password presuming and also password splashing; and also devices like Mimikatz, PowerSploit, and also BloodHound.

Initially launched as a PowerShell component, DeepBlueCLI has actually likewise been composed in Python for usage on Unix-like equipments.

Last word

Hazard knowledge and also risk searching are corresponding tasks in the day-to-day operations of a company’s protection group. As brand-new destructive projects emerge in the threatscape, it is important that companies have the ability to share expertise regarding what they are seeing so regarding repaint an extra comprehensive photo both of the most up to date tasks of recognized hazards and also of brand-new aggressors showing up on the scene. Protection experts are charged with arranging and also associating information from several and also often diverse resources. Based upon the enriched risk information, risk seekers can after that extra conveniently recognize any kind of hazards in their networks and also counteract them.
