Frequently Asked Questions
Should I Block AliyunSecBot?
Usually not, unless you already run your own security scans and want cleaner logs. AliyunSecBot checks for exposed vulnerabilities, and some services report their findings to site owners at no cost. For context, 1% of the top websites we track currently have robots.txt rules for AliyunSecBot.
Does AliyunSecBot Follow Robots.txt Rules?
Yes. AliyunSecBot is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether AliyunSecBot respects it.
Does AliyunSecBot Access Private Content?
It deliberately looks for exposed private content. AliyunSecBot tests login pages, admin panels, and API endpoints for vulnerabilities. Probing does not mean it gained access, but you should expect requests to sensitive paths in your logs.
Why Is AliyunSecBot Visiting My Website?
AliyunSecBot is scanning your site for vulnerabilities, either as part of an internet-wide sweep or because someone requested an assessment of your domain. Recurring visits often indicate that a monitoring service has added your site to its checks.
How Can I Tell if AliyunSecBot Is Visiting My Website?
Agent Analytics tracks AliyunSecBot visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "AliyunSecBot". Look for bursts of requests to uncommon paths that ordinary visitors rarely access. Because AliyunSecBot does not publish a verification method, any client can claim its identity and a log match is only a clue.
