Sleuth kit — It is a command line tool for analysis of forensic images.
FTK imager — It is a data preview and imaging tool.
Wireshark — wireshark is a packet analyzer used for network troubleshooting. analysis, software and communications protocol development.
CAINE — Computer Aided Investigation Environment. It is a live Linux distribution so it can be booted from removable media. It is an environment in which various FTKs are present and can be used at will.
Volatility — Volatility is an open-source memory forensics framework for incident response and malware analysis.
Registry recon — This tool has the ability to rebuild deleted parts of the registry.
Cellebrite UFED — UFED stands for universal forensic extraction device. This is the best commercial tool for mobile forensics.
Safety measures such as:

Keeping a strong password
Changing passwords frequently
Having a real time protection software for system protection
Updating protection software
Avoiding answering emails, messages and sms from unknown sources.
All these can result in being safe.

Now that we know what types of Cyber-crimes could occur and their solutions, tools and safety measures. This can be very beneficial in preventing Cyber-crimes and also gaing knowledge of how Cyber forensics works.
