IP address 44.220.188.219 conducted a high-volume attack campaign generating 2,170 events over a 3-minute window on March 26, 2026, targeting HTTPS services. The concentrated timeframe and attack volume indicate automated tooling consistent with reconnaissance or exploitation attempts against web applications. Network defenders should implement immediate blocking and enhanced monitoring for similar attack patterns.
Technical details
Attack Vector: HTTPS-focused campaign utilizing multiple TLS protocol versions (1.0, 1.2+) suggesting protocol downgrade attempts or broad compatibility testing. The attacker concentrated efforts on a single destination port, indicating targeted service enumeration. MITRE ATT&CK Mappings: T1595.002 (Active Scanning: Vulnerability Scanning), T1190 (Exploit Public-Facing Application). Attack Volume: 2,170 events compressed into 180 seconds (approximately 12 events per second) demonstrates automated tooling. Protocol Analysis: Mixed TCP SYN and established TLS connections suggest both port scanning and application-layer probing. IOCs: Source IP 44.220.188.219, attack window 05:00-06:00 UTC, concentrated burst pattern.

Recommendations
- Block source IP 44.220.188.219 at perimeter firewalls and web application firewalls immediately
- Implement rate limiting on HTTPS services to prevent similar high-volume automated attacks
- Monitor for additional sources exhibiting similar burst patterns of 10+ requests per second to web services
- Review TLS configuration to disable legacy protocol versions (TLS 1.0) and enforce modern cipher suites
- Enhance logging for rapid-fire connection attempts to identify future automated reconnaissance campaigns
