How Bots Are Scraping and Attacking Your Website
Check the raw server logs on almost any live website for even one day, and you will find requests from automated bots outnumbering real human visitors, often by a wide margin. Most site owners never look, so they never know.
Every row of automated traffic hitting your server looks identical until you actually look closely at what it is doing.

Automated bot traffic is one of those background realities of running a website that most small site owners are simply never shown, because it does not usually announce itself the way a defaced homepage would. It sits quietly in server logs, mostly invisible unless you specifically go looking.
Not all bots are attacking you, and that distinction matters
Before getting into the concerning categories, it is worth being clear that a large share of bot traffic is entirely legitimate. Search engine crawlers indexing your pages, uptime monitors checking your site is online, and services you have intentionally connected all generate automated requests too. The goal is not to treat all automated traffic as hostile, it is to recognize the categories that are not working in your interest and respond to those specifically.
What content scrapers are actually after
Scraping bots systematically copy content from your site, sometimes to republish it elsewhere for ad revenue, sometimes to feed large datasets, and sometimes for direct competitors trying to monitor pricing or product changes. For a blog specifically, this often shows up as your original articles appearing on low-quality aggregator sites, sometimes ranking in search results ahead of your own original post if the scraper's site has stronger technical SEO than yours. This is more of a content and business concern than a direct security threat, but it is a real, common cost of running any public content site.
Vulnerability scanners probing your site right now
A more directly security-relevant category is automated scanners systematically checking your site for known weaknesses, requesting common plugin paths, outdated software version signatures, and exposed files like the config file issues covered in an earlier post on this blog. These scans are usually not targeted at you personally, they are part of broad, indiscriminate sweeps across huge numbers of domains, looking for whichever sites happen to be running vulnerable, unpatched software. Being found by one of these does not mean someone specifically chose your site, it means your site was one of thousands checked in an automated pass.
Credential stuffing bots specifically targeting login pages
This category targets login forms directly, systematically trying combinations of usernames and passwords, usually pulled from previous data breaches, in the hope that some fraction of your users reused a password that was compromised elsewhere. This is not guessing at random, it is testing known, leaked credential pairs against your login form specifically, at a volume and speed no human attacker could manage manually. A site with no rate limiting or bot protection on its login page is an easy, low-effort target for this kind of automated attempt.
How to actually see this happening on your own site
| Signal | What it suggests |
|---|---|
| Repeated requests to the same login endpoint from many different IPs | Possible credential stuffing attempt |
| Requests for common plugin or config file paths that do not exist on your site | Automated vulnerability scanning |
| A user agent string that does not match a known browser or search engine crawler | Likely an unidentified bot, worth investigating further |
| Unusually high request volume from a single IP in a short window | Scraping or a basic denial-of-service style probe |
Most hosting control panels and platforms like WordPress expose at least basic access logs, and a quick scan of a single day's worth of entries is often more revealing than people expect. Tools like Cloudflare's bot management documentation, if you use it as a proxy in front of your site, also break down traffic by bot classification automatically, which removes most of the manual log reading entirely.
Reasonable defenses that do not block legitimate traffic
- Rate limiting on login and form endpoints specifically, the highest-value places to apply it
- A web application firewall, whether through your host or a service like Cloudflare, which filters a large share of obviously malicious automated traffic before it ever reaches your application
- Keeping your CMS, plugins, and themes updated, since scanners are specifically hunting for known, unpatched vulnerabilities, and an up-to-date site is a meaningfully less attractive target
- Two-factor authentication on any admin or login accounts, which renders a successful credential stuffing match against that account far less useful to an attacker on its own
- Checking your robots.txt file and considering it a polite request, not a security control, since well-behaved crawlers respect it but malicious scrapers generally ignore it entirely
Setting realistic expectations: you will not eliminate bot traffic from your site, and that is not really the goal. A small blog and a major retailer both deal with this constantly, at different scales. The goal is closing off the specific categories that pose real risk, credential stuffing against login pages and vulnerability scanning against outdated software, while accepting that some background level of scraping and crawling is simply part of having a public website at all.
Most of this traffic is invisible until you go looking for it, which is exactly why so few small site owners ever address it. A single afternoon spent reviewing your access logs, even briefly, tends to be more eye-opening than any general warning about bot traffic could be on its own.
