Malware refers to any type of malicious software that tries to infect a computer, phone or tablet. Hackers use malware for a variety of purposes, most of which involve extracting personal information, stealing money or intellectual property, or preventing owners from accessing their device.

So after asking “What is malware?” the next logical questions are, “who is creating it, and why?” The days when most malware was created by teenage pranksters are long gone. Malware today is largely designed by and for professional criminals.

These criminals may employ a variety of sophisticated tactics. In some cases, as technology site Public CIO notes, cybercriminals have even “locked up” computer data — making the information inaccessible — then demanded ransom from the users to get that data back.

But the main risk that cybercriminals pose to heavy computer users is stealing online banking information such as banking and credit card accounts and passwords. The criminal hackers who steal this information may then use it to drain your account or run up fraudulent credit card bills in your name. Or they may sell your account information on the black market, where this confidential information fetches a good price.
