Solution Overview

Problem

Organizations lack mechanisms to conduct security awareness training for calendar-based threats, such as malicious calendar invitations, which can compromise the security of sensitive information due to employees' unfamiliarity with these threats and implicit trust in electronic calendar applications.

Innovation Solution

Systems and methods are developed to provide calendar-based simulated phishing attacks that involve identifying context from user information, generating electronic calendar invitations with exploits, and detecting user interactions to determine risk scores and provide training, thereby enhancing security awareness for calendar-based threats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If organizations conduct security awareness training using traditional email phishing simulations, then employees can be trained to recognize email-based threats, but employees remain vulnerable to calendar-based phishing attacks due to lack of specific training on this threat vector

Engineering Contradiction:
Improvesecurity awarenessVSAvoidtraining coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The training system segments phishing threat education into distinct modules, with specific focus on calendar-based threats separate from email phishing. The system divides calendar invitation analysis into multiple detection dimensions including sender verification, link analysis, attachment scanning, and meeting detail validation, allowing comprehensive coverage of this specific threat vector

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary security analysis of calendar invitations before they reach users. Automated scanning of invitation links, attachments, and sender information occurs in advance, and users receive pre-configured security guidelines for evaluating calendar-based threats before encountering actual phishing attempts

Inventive Principle:
Principle #10Preliminary action

2Reliability

If employees are provided with comprehensive security training on all possible phishing vectors, then security awareness improves, but the complexity and cost of the training program increases significantly

Engineering Contradiction:
Improvesecurity awarenessVSAvoidtraining system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The training system applies localized, targeted education specifically for calendar-based phishing threats rather than generic comprehensive training. Security guidelines and detection techniques are customized for the specific characteristics of calendar invitations, focusing resources on this high-risk threat vector where specialized knowledge is most needed

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system introduces an intermediary automated analysis layer that scans and evaluates calendar invitations for phishing indicators. This intermediary tool provides users with pre-processed security assessments, reducing the cognitive burden on employees while maintaining comprehensive security coverage

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If automated systems scan and analyze all calendar invitations for phishing threats, then security detection capability improves, but system processing time and computational resources increase

Engineering Contradiction:
Improvethreat detection accuracyVSAvoidinvitation processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The automated scanning system applies partial analysis to all calendar invitations and excessive (comprehensive) analysis only to suspicious ones. High-risk indicators such as unexpected senders, urgent language, or unusual meeting requests trigger full automated scanning, while routine invitations receive streamlined processing, balancing detection accuracy with processing efficiency

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system implements rapid preliminary scanning that skips detailed analysis for obviously safe invitations. Common trusted senders and standard meeting templates are quickly validated without full phishing analysis, allowing the system to process high volumes of calendar invitations efficiently while maintaining security

Inventive Principle:
Principle #21Skipping (Rushing through)

4Reliability

If the system provides detailed security analysis and training for each calendar invitation, then user awareness improves, but user experience and ease of operation deteriorate due to excessive warnings and interruptions

Engineering Contradiction:
Improvesecurity awarenessVSAvoidcalendar usage convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system provides security feedback periodically rather than continuously. After initial comprehensive security education, users receive targeted alerts only for high-risk calendar invitations that exhibit multiple phishing indicators. Routine invitations receive minimal or no interruptions, maintaining user convenience while reinforcing security awareness through periodic engagement

Inventive Principle:
Principle #19Periodic action

AI summary

Systems and methods are described for providing calendar-based simulated phishing attacks to users of an organization. Initially, a context is identified for a calendar-based simulated phishing attack directed towards a user. An electronic calendar invitation for the calendar-based simulated phishing attack is then generated using the context. Thereafter, the electronic calendar invitation may be communicated to an electronic calendar of the user.
