Attack! Have You Heard of RansomWare – Wannacrypt?

RansomwareWhat is ransomware? Malicious software that locks a device, such as a computer, tablet or smartphone and then demands a ransom to unlock it.

How can you protect yourself? Anti-virus software can protect your machine, although cybercriminals are constantly working on new ways to override such protection.
Updating the OS will take care of most vulnerabilities. Do not click on questionable links or open suspicious attachments as this can save headaches. This helps limit the spread of ransomware if hackers do get into your system.

How does it work?

  1. The malicious Ransomeware software is normally contained within an attachment to an email that masquerades as something innocent. Once opened it encrypts the hard drive, making it impossible to access or retrieve anything stored on there – such as photographs, documents or music
  2. Ransomware is a kind of cyber attack that involves hackers taking control of a computer system and blocking access to it until a ransom is paid.
  3. It enters a computer when a user mistakingly clicks or downloads a malicious file
  4. It can also spread via a worm, embedding itself within a network, this is instead of relying on humans to spread by clicking
  5.  Experts warn that there is no guaranteed access given after payment
