CalConnect project to provide documentation on calendar spam best practices.

CalConnect CALSPAM Technical Committee

Background

In 2016, on "Black Friday", the day following Thanksgiving Day in the United States, many calendar systems were compromised by a wave of "calendar spam", unsolicited invitations delivered via email. These calendaring systems had no defenses against such an attack; there was no way for users to easily find and/or delete these unwanted events without sort of deleting the whole calendar. Calendar spam has repeated the history of email spam, with subsequent attacks being more subtle, more sophisticated, less dramatic, but equally difficult to detect and remediate.

Since then changes have been done to several calendaring systems to improve the handling of situations like that. CalConnect wants to offer their members in cooperation with the Messaging, Malware and Mobile Anti-Abuse Working Group (M3AAWG) information about best practices to cope with calendar spam.

Charter

The goal of this TC is to better protect users from receiving undesired information delivered through calendar systems, which currently range from spam to phishing attacks.

The TC aims to understand the current and potential usage of calendar systems as a vector for delivering undesired information; devise measures and best practices for developers and operators of those systems to ensure legitimate usage.

The TC works together with M3AAWG through CalConnect’s liaison relationship on the subject of calendar spam.

Out of Scope

Changing RFCs - at least for now.

Deliverables

  • A best practices document for calendar software in a format that is engaging for developers
  • Guidance on how mail and calendaring systems should interact with each other as joined work with M3AAWG

Begin and End Dates

  • Begin: February 2018
  • End: tbd

Milestones and Work Products

Period Milestone
