| Résumé: | Chain and multi-recipient e-mails pose significant security and privacy threats such as phishing and the spread
of Trojan horses. They also increase the chances of receiving spam e-mails. E-mails sent to multiple recipients
at a time result in unwanted exposure of e-mail address to multiple recipients. The recipients of chain e-mails
may include spammers or e-mail addresses of users whose e-mail account or device may have been compromised,
thereby, exposing all e-mail addresses to spammers. Forwarding or sending a multi-recipient e-mail in a chain
further increases the exposure of e-mail addresses to spammers. This paper discusses chain e-mails,
multi-recipient e-mails and crucial security and privacy threats they pose to legitimate e-mail user.
It also discusses various possible mechanisms to mitigate these threats and investigates their effectiveness.
This study proposes a novel technique to counter these security risks by enhancing the default behaviour of
e-mail client, SMPT server and SMTP protocol. The proposed technique has been implemented in the Java programming
language which showed promising results against unnecessary exposure of multiple e-mail addresses while sending
an e-mail to multiple recipients. |
