Spamware

What is spamware?
Spamware is a software utility specifically designed by spammers to spam. Spamware enables a user to search, sort, and compile a list of email addresses and provides an automated email broadcasting solution. This can be used to send spam or unsolicited email to unsuspecting recipients.
Not all software that sends bulk email is spamware, as email list server software can be used for legitimate purposes, not spam.

Spamware is based on the typical procedures, methods or processes that enable a spammer to deliver unsolicited e-mail. Most spam products focus on collecting email addresses and sending automated emails to everyone through a single platform.

This is done via bots that search email aliases from certain systems or websites. More advanced versions of spamware can fool spam filters or firewalls by changing the message header or using fake identities / IPs and / or inappropriate proxies.
