Unfortunately, scanning a large collection of files takes time. \nInstead, if a custom architecture is used, scanning 10TB of files can take around 30 minutes.\n\nKLara, a distributed system written in Python, allows researchers to scan one or more Yara rules\nover collections with samples, getting notifications by e-mail as well as the web interface when scan results are ready.\n\n# Features\n\n- Modern web interface, allowing researchers to \"fire and forget\" their rules, getting back results by [e-mail / API](/install/features_web.md)\n- Powerful API, allowing for automatic Yara jobs submissions, checking their status and getting back results. API Documentation will be released soon.\n- Distributed system, running on commodity hardware, easy to deploy and implement.\n\n# Architecture\n\nKLara leverages Yara's power, distributing scans using a dispatcher-worker model. Each worker server connects to a dispatcher\ntrying to check if new jobs are available. If a new job is indeed available, it checks to see if the required scan repository is\navailable on its own filesystem and, if it is, it will start the Yara scan with the rules submitted by the researcher \n\nThe main issue KLara tries to solve is running Yara jobs over a large collection of malware samples ( \u003e 1TB) in a reasonable amount of time.\n\n# Installing KLara\n\nPlease refer to instructions outlined [here](/install/)\n\n======\n\nIf you have any issues with installing this software, please submit a bug report\n\n# Contributing and reporting issues\n\nAnyone is welcome to contribute. Please submit a PR and our team will review it.\n\nYou can get in touch with us on our Telegram channel: [#KLara](https://t.me/kl_klara)\n\nThe best way to submit bugs or issues is using Github's Issues feature.\n\n# Credits\n\nKLara team would like to thank\n\n- Costin, Marco, Vitaly, Sergey\n- Current, former and future GReAT members!\n- Alex@grep\n- All contributors\n\nfor their amazing input and ideas. Happy hunting!\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FKasperskyLab%2Fklara","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FKasperskyLab%2Fklara","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FKasperskyLab%2Fklara/lists"}
