Server Software Component: Web Shell
Course Description

Your organization's enterprise server applications likely offer the flexibility of extensible features that your software developers can build upon so things work the way you need them to. However, bad actors can take advantage of that capability and use it to insert malicious code. In this way, they can achieve persistence on your network.

It's important to master the skills for detecting and mitigating this type of activity so you can keep attackers from reaching their end goals.

Get the hands-on skills you need to detect and mitigate this attack in Cybrary's MITRE ATT&CK Framework courses aligned to the tactics and techniques used by the financially motivated threat group Prophet Spider. Prevent adversaries from achieving persistence in your environment today.

Chris Daywalt

After too many years of security operations work, Chris Daywalt tries to turn his phone off at 5:00 pm EST. While there are a bunch of training classes and education somewhere on his resume, much of what he has to teach was learned at the school of hard knocks, often at the expense of his previous clients. He wants to help you spend more time detecting and denying adversaries and less time banging your head against your keyboard. He dips his blueberry donuts in orange juice.

Chris’ 19-year career includes work for organizations of all sizes, both government and private sector, and is distributed roughly like so:

  • 30% doing DFIR
  • 30% teaching DFIR
  • 20% monitoring and detection engineering
  • 15% risk assessment
  • 5% other stuff, like sneaking in a game of Plants vs. Zombies or taking a quick nap at the desk (Don’t judge - I work overtime)
