Currently, there are some web-based applications that provide this kind of service openly, and some with possibly malicious uses. In fact, malware threats have been using these services to map out and identify their targets for quite some time to already - an acknowledged fact hidden in technical write-ups but which hold little recognition for an active defender. The goal of looking into these web services is to isolate threats that had abused the network service and identify this kind of network activity. If we can associate an external IP lookup to a suspicious activity, then we would be able to assume that an endpoint requires some form of investigation. Endpoint identification through IP addresses may pose a challenge, but the correct placement of the identification methods proposed in this paper may be considered. This paper will also look into the associated malicious activity that had used online services, the use of such services over time, differentiate the threats that use them, and finally how to detect them using open source tools, if applicable.
