SMTP Authentication

Hello everyone.

I am back with some more email security!

Today I’d like to talk about SMTP Authentication.

Cellebrite (https://cellebrite.com) is an Israeli company that specializes in mobile forensics.

They have created a well known product that is called Universal Forensic Extraction Device (UFED). This tool basically can extract data from most mobile devices.

My assumption is that a lot of the data is related to tools and software made use of for forensic investigations. (more…)
