  • When Checking the Box Results in Two Zero Days and Root (CVE-2019-14257 and CVE-2019-14258)

    August 21, 2019, Jakob Nelson, Associate, Coalfire Labs

    Finding new bugs and exploiting them can be exciting and fun for a penetration tester. I was ecstatic to find my first two zero-days, and I used them to break a system from no access to root. This was a good day for me – but the story behind the story provides some real lessons enterprises can apply to their security programs.

  • Introducing Slackor, a Remote Access Tool Using Slack as a C2 Channel

    June 19, 2019, Esteban Rodriguez, Consultant, Coalfire Labs, Coalfire

    As a penetration tester at Coalfire Labs, I frequently use exploitation frameworks such as Metasploit or PowerShell Empire to perform post-exploitation actions on compromised endpoints. While anti-virus (AV) bypass and detection avoidance is often trivial in all but the most mature environments, detections from AV have caused me to look toward custom tooling to mitigate the risk of being detected by both traditional AV as well as security operations teams relying on network indicators. Over the past year I’ve been slowly developing my own tooling to deal with these challenges.

    Have a checklist of tasks you perform every penetration test, such as SSH bruteforcing or port mapping? Automate it with Python and Metasploit! Unfortunately, there hasn’t been a working, full-featured Python library for making these tasks easy for many years now. This changes today.

  • The Death Metal Suite

    April 09, 2019, Victor Teissler, Security Consultant, Coalfire

    Intel Active Management Technology (AMT) is a feature provided by Intel for remote administration. If you happen to have a corporate laptop, odds are you too have AMT built into your system. To a sysadmin, AMT eases access to machines for the sake of assisting employees with technical issues, even if the hard drive has failed or been affected by ransomware. This is due primarily to the fact that AMT does not require a functioning operating system for accessibility. Its configuration and operating environment reside completely within its own dedicated hardware!
