A spam email is sent to as many email addresses as possible, these are obtained from various sources, previous hacks, social media etc
Anti-Spam filters will stop the majority – 99%, but some still get through
The email is either a link to a compromised website (such as WordPress) or it is an attachment with a zip file which anti-spam filters cannot scan
Gateway Security – stops traffic to some of the locations where these files are hosted but not all…
The user receives the email, it’ll look legitimate, possibly even with personal information to validate it. Your home address, sometimes even your phone number and or full name will be on it. It’ll have a zip file or a link, with a password to open it.
Most users will ignore the email and dismiss it as spam, some will open the link/attachment and let the virus run.
Once the Virus is executed, it’ll use the machine as a temporary host, then start searching for any potential venerable machine, searching for any potential weakness it can exploit, it’ll run this constantly until it is destroyed by a virus checker or a kill switch is activated.
