Email worm

An email worm, or mass-mailer, is a type of an internet worm (or virus) cybercriminals use to infiltrate their victims’ inboxes. Hackers usually deploy worms as attachments to fraudulent email messages. These attachments allow the worm to distribute itself in infectious executable files. Email worms self-download files and delete all security software on users’ devices. They also pose a grave security threat to email programs and brands’ IT infrastructure by creating their own copies and attaching to emails.
