Ransomware BISD Technology Department

Ransomware Ransomware is a type of malicious software (malware) that infects a computer and/or mobile device and restricts access or locks down the device until a ransom is paid. Ransomware infections have seen exponential growth in 2016 with hackers using craftier methods to attack unsuspecting users.

Ransomware Not only can ransomware encrypt the files on your computer, the software is smart enough to travel across the network and encrypt any files located on shared network drives. This can lead to a catastrophic situation where one infected user can bring an entire company (or school district) to a halt!

How bad can it be? Photos Music Videos Documents Financial Health Teaching/department Documents

What Operating Systems Can Ransomware Affect?

“The adage is true that the security systems have to win every time, the attacker only has to win once.” – Dustin Dykes

How does ransomware spread? – The hackers attach viruses to s that are designed to focus you on bogus content instead of looking for a virus. Beware of links and attachments, especially “.exe” and “.zip” files.

How does ransomware spread? You have won something You owe money Your password is expired Forms asking for personal information If a device is infected, information on that device can be used to infect others
