This threat is becoming more relevant as more and more defenses are relying on digital signatures for allowing or not execution on an endpoint. This project aims at collecting the details of the certificates that are known to be abused in the wild by malicious actors.\n\nThe `scripts` directory contains a Python script used to generate Yara rules for all the certificates.\nRules are written according to [Nextron System - Short tutorial how to create a yara rule for a compromised certificate](https://www.nextron-systems.com/2018/11/01/short-tutorial-how-to-create-a-yara-rule-for-a-compromised-certificate/).\n\nTo generate all the yara rules:\n\n```\ncd scripts/\npython3 generate_yara.py\n```\n\nSchema:\n```yml\nname: name_of_the_certificate\nmeta:\n  status: revoked|valid\n  source: leaked|malicious\n  description: |\n    Brief description of the certificate and where was it obtained from\n  references: Threat intelligence reference\n  date: Date of release\n  author: Author Name\nissuer: Issuer of the certificate\ntimestamp: Unix timestamp of when the cert was leaked, if relevant\nserial: Array of strings containing the serial numbers of the certificates\nthumbprint: Optional array of strings containing the thumbprints of the certificates\n```\n","funding_links":[],"categories":["DevOps","Certificates"],"sub_categories":["General"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FReversecLabs%2Flolcerts","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FReversecLabs%2Flolcerts","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FReversecLabs%2Flolcerts/lists"}
