Hackers are very nice… with no prejudice, they target everyone equally, and no organization is not immune to such attacks.
A ransomware is a little program (aka virus) that will encrypt all of your files AND any shared company drive that you happen to be connected to at that time. The hacker then leaves a file asking for a ransom ($) in order to recover the files.
Four levels of protection are needed to be effective and safe:
- A network firewall blocks most attacks at the front door of the company
- Antivirus with sophisticated monitoring is running on all machines
- Market leading anti-spam protects the email system
- YOU are needed to be on the lookout for any suspicious email or link.
Where ransomware lurks and what to look for:
- Zipped files or documents sent via email from an unknown source -> verify with the sender by phone first, or simply delete the mail.
- Some other popular files including viruses are disguised as a resume or a possible invoice. If a security warning asks about enabling a macro, please ensure you trust the source and file before clicking yes.
- Ransomware can also be downloaded from unknown websites offering free stuff or contests or other attractive offer.
