WHAT IS A Mass-mailing worm?

A mass-mailing worm is a type of malicious software that replicates itself and spreads by sending copies of itself to contacts in an infected user's email address book. It typically exploits vulnerabilities in email clients or operating systems to propagate quickly and can cause significant disruptions by overwhelming email servers and spreading malware. These worms may also carry payloads that can damage files or steal personal information. They are often designed to operate without user intervention, making them particularly dangerous.
