Rapid Cyber Core Spring Edition

CybExer Technologies will organize the RAPID CYBER CoRe (Cooperative Resilience) event in online format from 28-29 April 2021. During the 2-day event your Blue Team skills will be tested in a live-fire exercise of defending a full-scale IT Infrastructure against Red Team cyberattacks.

The RAPID CYBER CoRe event is an excellent opportunity for your IT security team to test their methodology and skills of mitigation, detection and response to high frequency cyberattacks that will be launched on their IT infrastructure. Multiple Blue Teams participate in the exercise and compete against each other to keep their IT infrastructure protected against attacks performed by a real-life Red Team and test their capabilities under the pressure of a continuous flow of attacks and real-life based scenarios. Participating in this event is an excellent way to test and develop your skills in handling real-life cyberattack by means of Identification, Protection, Detection, Response, Recovery and Reporting.

Exercise format updates

  1. Shortened time of the exercise – exercise lasts two days and actual engagement for participating teams is one day (first day is for voluntary preparations and familiarization in gamenet, second day for actual gameday);
  2. Cut down the network size and Red Team campaign to accommodate teams with minimum 4 members and maximum 6 members;
  3. Added additional challenges besides live-fire element – mainly addressing the current threat landscape incidents:
    1. Investigating e-mail based social engineering attacks;
    2. Handling IT resources misuse incidents related to CryptoJacking;
    3. Reverse engineering.

Critical Infrastructure Component

The exercise also includes Critical Infrastructure (CI) component.

Exercise Gamenet includes a fully virtualized simulation of Energy Company control room related systems that are used to manage energy distribution network. Exercise participants will have to defend the Human-Machine Interface (HMI) in the control room that visualises a processes in a critical infrastructure that is not related to IT systems. The data sources are operated by the exercise organizers and are not subject to attacks and defenses.
