TL;DR

This study analyzes a real-world, large-scale phishing campaign targeting Meta users, combining technical forensics with sentiment analysis of victim responses. Using data from 25,000 victims, it reveals poor password choices—over 60% of passwords were leaked over two years prior—and high rates of re-victimization, while sentiment analysis shows victims acted under stress, often during work hours, despite clear red flags in the scam's design.

ABSTRACT

In an era dominated by digital interactions, phishing campaigns have evolved to exploit not just technological vulnerabilities but also human traits. This study takes an unprecedented deep dive into large-scale phishing campaigns aimed at Meta's users, offering a dual perspective on the technical mechanics and human elements involved. Analysing data from over 25,000 victims worldwide, we highlight the nuances of these campaigns, from the intricate techniques deployed by the attackers to the sentiments and behaviours of those who were targeted. Unlike prior research conducted in controlled environments, this investigation capitalises on the vast, diverse, and genuine data extracted directly from active phishing campaigns, allowing for a more holistic understanding of the drivers, facilitators, and human factors. Through the application of advanced computational techniques, including natural language processing and machine learning, this work unveils critical insights into the psyche of victims and the evolving tactics of modern phishers. Our analysis illustrates very poor password selection choices from the victims but also persistence in the revictimisation of a significant part of the users. Finally, we reveal many correlations regarding demographics, timing, sentiment, emotion, and tone of the victims' responses.

Motivation & Objective

• To investigate the technical and psychological dimensions of a large-scale, real-world phishing campaign targeting Meta users.
• To understand victim behavior beyond technical exploits by analyzing free-text responses, sentiment, and emotional tone.
• To identify patterns in password selection, response timing, and re-victimization across diverse demographics.
• To evaluate the effectiveness of current phishing detection and awareness strategies in light of real victim behavior.
• To provide actionable insights for improving cybersecurity awareness by focusing on behavioral and psychological factors.

Proposed method

• Collected real-time data from active phishing campaigns targeting Meta users, including credentials, free-text responses, and timestamps.
• Applied natural language processing (NLP) and transformer-based models to analyze sentiment, emotion, and tone in victims’ textual inputs.
• Used machine learning to correlate victim responses with timing, demographics (inferred), and behavioral persistence.
• Conducted password analysis by cross-referencing victim-provided passwords against historical breach databases.
• Identified patterns in response timing, showing peak activity during weekdays and business hours.
• Evaluated operational flaws in the phishing infrastructure to validate data authenticity and campaign scale.

Experimental results

Research questions

• RQ1 What are the dominant psychological and emotional states of victims during phishing interactions, as revealed by their free-text responses?
• RQ2 How do victim password choices correlate with known data breaches, and what does this imply about long-term cyber hygiene?
• RQ3 To what extent do victims re-engage with phishing platforms or respond to follow-up emails, indicating persistent vulnerability?
• RQ4 How do response timing and demographic patterns (inferred) correlate with susceptibility to phishing attacks?
• RQ5 What role do logical inconsistencies in phishing emails (e.g., use of unrelated third-party services) play in victim decision-making?

Key findings

• Over 60% of victim passwords had been previously leaked in data breaches, with many used more than two years prior.
• A significant proportion of victims—over 20%—repeatedly interacted with the same phishing platform or responded to follow-up emails, indicating persistent re-victimization.
• Victims most frequently responded to phishing emails during weekdays and business hours, suggesting heightened stress or urgency during work periods.
• Sentiment analysis revealed high levels of anxiety and urgency in victims’ textual responses, despite clear logical inconsistencies in the phishing message.
• The phishing campaign exploited multiple third-party services (e.g., Salesforce, Google) in a way that defied logical service integration, yet thousands still complied.
• Despite obvious red flags—such as Meta using external platforms to request credentials—many victims failed to recognize the scam, indicating a systemic lack of cyber hygiene.
