    We have discovered a critical issue with certain versions of the Cb Response Binary Detonation integrations released in the last month. A patch that was rolled out to the Binary Detonation integrations in September erroneously submitted corrupt files to the binary detonation providers, potentially resulting in invalid responses from the analysis platform. No sensitive information was leaked as part of this bug. Specifically, the first five bytes of the file were missing on every submission of a file to a binary detonation appliance.

    Posted on Aug 8, 2017

    We are pleased to announce the release of an updated Cb Reporting script. https://github.com/carbonblack/cb-reporting/blob/master/incident_report.py The incident report script is an example python program that demonstrates how to build a basic incident report using the Cb API bindings for python.

    The Cb Community Repository

    Posted on Aug 4, 2016

    We encourage everyone to release their code publicly on GitHub but on the other hand understand that contributions come in all shapes and sizes. Some contributions, like Red Canary’s Surveyor or Bobby Argenbright’s Forager tool, warrant their own repository (and in some cases, their own cool icon!) However, other contributions may be a single script or a few lines of API code. To help collect these smaller contributions into one place, we’ve created the new Carbon Black Developer Community GitHub organization, available at https://github.

    What a difference a year makes! Almost a year ago, we released a bunch of new features in cbapi to help developers become more productive with the Carbon Black Enterprise Response REST API. Since then, we’ve changed the name of the company, created an entirely new Developer Network website, created a new, even easier-to-use and more powerful Python API, and most importantly, merged the APIs for both Enterprise Response and Enterprise Protection into the same code base!

    It’s been an exciting few weeks for us on the Carbon Black blog. In addition to discussing the efficacy of Patterns of Attack versus Indicators of Compromise, we’ve talked about shifting the economic balance of cyber-attacks, the “story” your data is trying to tell you and, perhaps most importantly, the importance of sharing the right kind of threat intelligence to form a Collective Defense. Today, I’m proud to reveal Carbon Black’s specific initiatives in the realm of Collective Defense in an effort to unite the cyber-security community in the battle against common adversaries.
