Ratware
From Wikipedia, the free encyclopedia
Ratware is a fairly new term that is used to represent the underlying software used by mass-mailers (another equivalent word is spammers) to achieve their objective of delivering large amounts of email in a short span of time.
Ratware (spammer’s software) is capable of providing false or inaccurate information in SMTP dialogues with a view to impersonate, evade detection and spoofing.
Ratware is most often installed on Zombie computers through means of malware such as viruses, worms and trojan horses.
