However, 375 rules were rejected to be published. SOC Prime carefully validates all detections received for review, and the most common rejection reasons are detection duplications and pitfalls in detection logic. To avoid such situations, we highly recommend all content developers willing to monetize their detections with the Threat Bounty Program take into consideration the recommendations of the Sigma Rules Guide

Also, before creating a new detection in terms of the Threat Bounty Program, we recommend checking with the Sigma rules search engine whether similar detention already exists, and utilizing the Lucene search option to look for possible similar detection patterns within Threat Detection Marketplace.

Threat Bounty content authors may submit detections using Developer Portal or Sigma Rules Bot. Learn more about how to start monetizing your detection engineering skills with Threat Bounty Program. 

As for the most demanded content, we recommend our Threat Bounty developers focus on the following:

Unique own-developed detections for existing and emerging threats, especially critical CVEs and ongoing campaigns.
Rules for detecting possible attacks against organizations of the public and private sector who openly support and follow the sanctions against the russian federation and thus may become the target of the attack. This includes detections for possible exploitation of vulnerabilities in technologies actively used in the organizations. 
Detections for possible attacks against critical infrastructures, including ICS-capable malware, wipers, and other destructive strains.
