Common threats cybercriminals use
Now you know a few very common ways cybercriminals try
to sneak onto your device or trick you into providing private
information to them directly. Here are a few of the types of
malware they like to deploy once they've got into a device
and what to do if you're ever infected.
Ransomware
A form of malware that will encrypt personal data files on
your computer and attached devices. Encryption converts
files into another format, that can only be opened with a
specific decryption key. Once the ransomware installs itself,
it will display a warning message that the computer is now
locked. The user is given a specific amount of money to pay
as a "fine" and a timeframe in which to pay. Even if paid, the
criminal might choose to not unencrypt the files anyway!
What to do if you're infected:
Avoid getting infected in the
first place by staying protected with internet security
software like Norton Security. Also, perform regular
backups of all your data either online or to a separate
external hard drive that is
only attached
to your computer
while performing the backup. Ransomware has been known
to lock access to external hard drives attached to the
computer.
If you are infected with ransomware, think twice before you
pay the ransom. There is no guarantee the cybercriminal will
unlock your files and you'll be funding them to prey upon
another innocent victim.
Botnets
A botnet is a string of infected, connected computers
coordinated together to perform a task. Botnets gain access
to your machine through some piece of malicious coding.
Once the software is downloaded, the botnet will now
contact its master computer and let it know that everything
is ready to go. Now your computer, phone, tablet, or IoT
