Log Indicators:
- Unusual file uploads (e.g., .php, .jsp, .asp files)
- HTTP requests to uploaded files with execution patterns
Network Indicators:
- HTTP POST requests to upload endpoints from untrusted sources
- Outbound connections from server to unknown IPs post-upload
SIEM Query:
source="web_logs" AND (uri CONTAINS "/upload" OR file_extension IN ("php", "jsp", "asp")) AND response_code=200
