Repeated requests for random .php paths are usually automated probes: bots guess filenames associated with popular software, plugins, or known weaknesses and check how a server responds. A request in your log proves only that someone tried a path. It does not prove the file exists, the attempt worked, or your site was compromised.
Why bots request PHP files your site may not have
Automated scanners send requests for recognizable files and endpoints across public websites. Some look for web shells or files with potentially sensitive extensions; others test paths associated with widely used applications. The peer-reviewed study Good Bot, Bad Bot: Characterizing Automated Browsing Activity documents these kinds of automated browsing patterns. Its findings describe the study’s dataset, not a universal rate of PHP probing across websites.

A scanner may try WordPress paths even if your site does not use WordPress. That is a reasonable explanation when a bot tests familiar paths across many hosts without first identifying each site’s software, but a particular log entry cannot establish the scanner’s method or intent. WordPress identifies xmlrpc.php as a frequent brute-force target and notes that attacks can be distributed across sources in its brute-force guidance. A request for that or another WordPress path does not show that WordPress is installed.

What a PHP request in your log does—and does not—tell you
An access-log entry records an attempt to reach a URI. To understand what happened, examine the response status and the surrounding activity, rather than drawing conclusions from the filename alone.
#1 Best Overall
- ENDLESS POWER FROM SOLAR ENERGY: Just 45 minutes of direct sunlight powers the camera for a full day of use, while the built-in battery lasts up to 180 days on a single charge during cloudy days. Solar charging requires temperatures above 32°F.△
- EASY WIRE-FREE INSTALLATION: Place the Tapo SolarCam C402 KIT where you need it without relying on nearby outlets. Install the camera and solar panel together or separately using the included 13 ft cable for flexible placement.
- PRIORITIZE WHAT MATTERS: Set activity zones to monitor specific areas for motion or people. Free person and motion detection helps reduce unwanted alerts and notifies you when activity is detected.
- VERSATILE VIDEO STORAGE: Store footage locally via a microSD card (up to 512GB)* or via cloud with a Tapo Care cloud subscription. Tailor your security to suit your needs, whether indoor or outdoor, you have the storage option you need.
- FULL-COLOR 1080P, DAY AND NIGHT: See clearly in low light with a large-aperture lens and built-in spotlights. Capture full-color night vision up to 30 ft away to monitor for possible intruders or motion.
- A 404: Consistent with a request for a nonexistent path, but not a complete security assessment.
- A successful response: Worth investigating, especially if the path is sensitive or unexpected. A success code alone still does not tell you whether data was exposed or code ran.
- Repeated requests or sequences: May indicate automated probing. Check whether requests arrive in a recognizable pattern, whether sources vary, and whether the same paths recur.
- Performance changes or unexpected behavior: Check for service degradation and corroborating signs such as altered files, unfamiliar accounts, or other unauthorized access.
There is no general request-rate cutoff that separates harmless scanning from an incident. The sources available here do not establish one; urgency depends on your site’s responses, operational impact, and other evidence.
How to assess the requests
- Inspect the full request. Note the URI, HTTP method, response status, timestamp, and source details available in your logs. Look for repeated paths or sequences, not just isolated filenames.
- Check whether the path belongs to your site. Identify which CMS, plugins, themes, integrations, or custom features are installed and whether any rely on the requested endpoint.
- Look for corroborating indicators. Investigate successful access to sensitive resources, unusual application behavior, changed files, unfamiliar accounts, and service degradation.
- Review maintenance and monitoring. Keep the web server and exposed application components patched. NIST’s Guidelines on Securing Public Web Servers includes patching, upgrades, log monitoring, and backups among its recommendations.
Choose a proportionate response
If the requests are failing and have no operational impact, monitor them and keep your software maintained rather than blocking every unfamiliar filename. If traffic is burdening the site or probing real endpoints, a firewall rule may help—but preserve the paths your site needs.

| Response | Where it acts | Trade-off to consider |
|---|---|---|
| Edge or hosting-provider WAF | Between incoming internet traffic and the hosting server | Can filter traffic before it reaches the origin; verify that legitimate requests and required endpoints still work. |
| Web-server or application rule | At the origin server or application | Offers direct control, but may not prevent the request from reaching the origin; keep exceptions for legitimate PHP endpoints. |
| Monitoring and log review | Observes requests and outcomes | Preserves visibility for investigation but does not itself block traffic. |
WordPress describes a website firewall as an intermediary between internet traffic and hosting, and recommends edge or WAF protections to block harmful traffic before it reaches the server. See its hardening guidance and brute-force guidance. These are general protective options, not a finding that a specific request is harmful.
