GreyNoise launches free scanner to check if you're part of a botnet By Bill Toulas November 27, 2025 GreyNoise Labs has launched a free tool called GreyNoise IP Check that lets users check if their IP address has been observed in malicious scanning operations, like botnet and residential proxy networks. "Sometimes folks knowingly install software that does this in exchange for a few dollars. More often, malware sneaks onto devices, usually via nefarious apps or browser extensions, and quietly turns them into nodes in someone else's infrastructure."

GreyNoise Labs has launched a free online scanner, the GreyNoise IP Check, designed to determine if a user’s IP address has been observed within malicious scanning operations, such as those associated with botnets and residential proxy networks. The firm’s ongoing monitoring efforts reveal a significant increase in these activities over the past year, with many users unknowingly contributing to malicious online operations. This often occurs due to the proliferation of residential proxy networks, where home internet connections are utilized as exit points for other people’s traffic, frequently facilitated by users installing software for a few dollars or by malware silently infecting devices. The scanner’s functionality is straightforward, providing one of three possible results: “Clean,” indicating no malicious scanning activity, “Malicious/Suspicious,” suggesting scanning behavior has been detected and requiring further investigation, or “Common Business Service” flagging the IP address as belonging to a VPN, corporate network, or cloud provider, where such scanning is typically normal. Regardless of the result, the platform offers a 90-day historical timeline of activity correlated with the IP address, which can assist in pinpointing potential infection points, particularly when correlating the IP address with the installation of bandwidth-sharing clients or questionable applications. For more technically inclined users, GreyNoise also provides an unauthenticated, rate-limit-free JSON API accessible via curl, allowing for integration into scripts or monitoring systems. A “Malicious/Suspicious” result warrants a thorough investigation, typically beginning with malware scans across all devices on the same network, with particular attention to routers and smart TVs. Recommended remediation steps include updating device firmware, changing admin credentials, and disabling remote access features if they are not required. Essentially, the tool provides a readily available method for individuals to assess their potential involvement in malicious network activity, emphasizing the importance of proactive security measures. |
