ELCOMSOFT PASSWORD RECOVERY & DATA DECRYPTION

This class is offered in partnership with Elcomsoft, Russia’s leading password recovery, data decryption and mobile forensics service providers.

Course Objective

In this 3-day Password Recovery and Data Decryption for Mobile Forensics Course, students will develop an in-depth knowledge of password protection and data encryption techniques used in mobile forensics. The attendees will further master modern technologies for password recovery, mobile forensics, data extraction and decryption.

In Part 1 of this course students are led through the fundamentals of Mobile Forensics including; an overview of common platforms, operating systems, workflow, logical acquisition, physical acquisition, and cloud based acquisition.

In Part 2 students will be instructed in the fundamentals of Encryption, Data Protection, and Passwords, including; brute force, smart attacks, dictionary attacks, how to avoid lengthy attacks, and much more.

Attendees who successfully pass the class assignments will be given a certificate of completion.

I left with a far better understanding of the linear differences between backup / sync features which I had not previously investigated. I found that it has already paid for itself in our interaction with investigators. Probably one of the better instruction training I have had in a while. I will definitely be recommending Vlad and Oleg for future training with our members. Good job guys.

Who can take this course?

This training course has been designed for digital forensic investigators, law enforcement personnel, e-discovery, and IT security specialists looking to further develop their mobile forensic skill sets to encompass password recovery and data encryption.
