Different types of cyber crime
One of the most common I have heard of is phishing: - this is when you send out emails claiming to be big name companies and try and get passwords, card numbers from someone, so really anything that could expose money or accounts you have.
The emails these ''Scammers'' will send will tend to have some form of link and/or a file to download. This will most likely take you to a dangerous site or install a malware onto your PC to once again steal any data of worth.
They make the emails look so convincing by stealing information right from big company websites and throw in logos and they can also do spoofed ULRs so you might think its safe but then it installs a malware or any form of virus.
Another one I hear a lot about is DDoSing or distributed denial-of-service: - This is when someone with access to multiple IPS (Servers) will send a massive flood of data (traffic) to another server (network) in the hope that it will shut it down.
From what this site tells me there are three types of DDoS people can do they are as follows: -
Traffic Attack - Data gets lost and can force in malware sent by the hacker
Bandwidth Attack - Overloading your system with junk data
Application Attack - (Not sure about this one)
But they are all trying to achieve the same goal of shutting you or a company network down.
