Q1 2026 Attack Landscape Report: Key Findings for WAAP Teams
As the first quarter of 2026 closes, it’s time to take stock of the attack landscape. The data from January through March reveals several significant shifts in how web applications and APIs are being targeted — and how defenders need to adapt.
Attack Volume Metrics
Total web application and API attacks recorded across major WAAP providers increased 41% compared to Q1 2025. The average organization faced 1,847 distinct attack events per week, up from 1,312 in the same period last year.
Attack Type Breakdown
API-Specific Attacks Now Dominant
For the first time, API-specific attacks (attacks targeting API endpoints specifically, rather than web pages) accounted for more than half of all detected events: 53% versus 47% for traditional web attacks. This marks a milestone in the ongoing shift from web to API attack surfaces.
Credential Stuffing Leads the Charts
Credential stuffing was the single most detected attack type, representing 28% of all events. The volume is driven by massive password lists circulating from 2025’s major breaches. Organizations with strong login rate limiting saw 98% fewer successful credential stuffing events.
SSRF Attacks Rising Fast
Server-Side Request Forgery attacks grew 67% quarter-over-quarter, driven largely by the proliferation of AI-powered features that fetch external content. Many WAAP deployments still lack SSRF-specific detection rules.
Bot Traffic Reaches New Peaks
Malicious bot traffic averaged 34% of all web traffic in Q1, up from 29% in Q4 2025. The post-holiday bot surge was the primary driver, but bot activity remained elevated through March.
Industry-Specific Findings
Financial Services
Financial institutions faced 3.2x more API attacks than the cross-industry average. Account takeover attempts via API were the primary vector, with attackers exploiting session management weaknesses in mobile banking APIs.
Healthcare
Healthcare organizations saw a 73% increase in data scraping attempts targeting patient portal APIs. The upcoming HIPAA API security requirements (effective June 2026) are driving attention to vulnerabilities that have gone unaddressed for years.
E-Commerce
E-commerce platforms experienced a 92% increase in inventory hoarding bot activity. Automated checkout bots are increasingly sophisticated, mimicking human purchasing patterns to bypass behavioral detection.
Key Takeaways for Q2
- API-first attack surface requires API-first defense. If your WAAP configuration treats API protection as a subset of web protection, it’s time to reconsider.
- Credential stuffing is the most impactful threat you can mitigate. Proper rate limiting alone cuts successful attacks by 98%.
- Bot detection must evolve beyond IP-based blocking. Session-level behavioral analysis is now table stakes.
- SSRF protection is no longer optional. Every WAAP deployment handling AI-powered features needs SSRF-specific rules.
