Phishing attacks are no longer rare outliers. Across 2023 reporting, victims and investigators saw phishing tied to huge volumes of email delivery and major breach and loss categories, including $1.28 billion in FBI IC3 phishing related losses and phishing as the leading cause of data breaches in Verizon’s DBIR social engineering segment. With 99.99% of phishing attempts blocked in Google managed infrastructure, the real question becomes why so many still get through and what “one click” means at scale.
Key Takeaways
- In 2023, “phishing” was the second-most common cybercrime type reported to the UK’s Action Fraud by victims (after fraud/billing scams)
- Attackers sent 3.4 billion phishing emails per day in 2023 (global estimate)
- Phishing is the #1 cause of data breaches for 60% of breaches reported in Verizon’s DBIR (in the ‘social engineering’ category)
- 54% of organizations in a 2023 survey reported using email security solutions with anti-phishing capabilities (Gartner Peer Insights / industry survey summary).
- 76% of organizations reported using some form of phishing simulation training for employees (2024 survey), reflecting widespread adoption of security awareness activities.
- 50% of organizations in a 2024 survey said they used MFA to mitigate phishing risks, meaning multi-factor authentication is commonly viewed as a control for email-based credential theft.
- In the 2024 Google Transparency Report, 99.99% of phishing attempts were blocked before reaching users across Google-managed infrastructure in the reported measurement period.
- In Google’s Safe Browsing / phishing protection reporting, 100% of phishing URLs detected by Safe Browsing are checked and blocked in supported contexts (blocking metric published by Google).
- $2.8 million is the estimated average cost of ransomware incidents where initial access used phishing in a 2023 analysis by Sophos (cost model using industry breach case studies).
- Phishing is responsible for 20% of cyber risk events that lead to incident response costs in IBM’s Cost of a Data Breach benchmark analysis (phishing-driven initial access segment).
- In 2023, reported ‘phishing’ losses in the UK Action Fraud platform were within the overall social engineering/fraud reporting categories totaling hundreds of millions of GBP (UK case records aggregated by the NCSC/UK reporting), showing large aggregate financial harm.
- 65% of organizations experienced a phishing attack at least once in the past 12 months (2023 survey), indicating phishing is highly prevalent across enterprises.
- Microsoft observed that email is responsible for the majority of malware delivered to users as part of phishing and social engineering campaigns (2023/2024 Microsoft Security research), showing delivery-channel concentration.
- RSA SecurID breach events reported by CISA involved phishing emails used to obtain initial access, quantifying phishing’s role in documented real-world intrusion cases.
Phishing remains the leading entry point for major breaches and fraud, costing billions globally despite widespread defenses.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
