Reverse engineering is the ultimate hacking. We can crack, modify and hack client applications.

How we Rock


1. Scope

By determining the extent of the scope and the type of security audit, we agree on time and price with you.

2. Reconnaissance

We get to know the target scope by examining the system its architecture, programming language and functionalities.

3. Scanning

In order to find obvious issues concerning security we use a set of tools which help us during the process of penetration testing.

4. Target Penetration

In-depth and fully manual penetration of the system based on our reconnaissance and previous findings. This process takes up to 80% of the entire security test.

5. Reporting

Through reporting we list all the found vulnerabilities, their best practice solutions and a risk analysis to prioritize patch management.
