Ransomware is malware that gets installed on a PC user’s workstation using social engineering attacks where the user gets tricked into clicking on a link or opening an attachment. Once the malware in on the machine, it starts to encrypt all data files it can find on the PC itself and any network shares the PC has access to.
When a user wants to access one of these ﬁles they are blocked and unable to use the ﬁle – this can be a severe problem for business’ critical data. The system administrator who investigates this problem typically ﬁnds two ﬁles in the directory that indicate the ﬁles are taken ransom, and how to pay the ransom to decrypt the ﬁles.
Once encrypted the only way to way to get them back is to restore a recent backup or pay the ransom. These ransoms are about $500 within the ﬁrst deadline and can double if the deadline expires.
Ransomware uses social engineering techniques to trick the user into running it. Commonly, the victim receives an email with a password-protected ZIP ﬁle purported to be from a company.
The Ransomware gets run when the user opens the attached ﬁles, which are often ZIP ﬁles, DOC or PDFs. So when in doubt, delete the email and the attachment
