Example analysis of using ZoomEye to find APT attacks

The data online on ZoomEye is in overwrite and update mode, which means that if the data is not scanned in the second scan, the updated data will not be overwritten. The data on ZoomEye will retain the banner data obtained in the first scan. This mechanism is here In fact, there is a good scene fit in the traceability of this kind of malicious attack: the download servers used by malicious attacks such as Botnet, APT and other attacks are usually directly deactivated and discarded after being discovered. Of course, some are hacked targets, and they are also very violent. Go offline directly! Therefore, many attack sites are likely to be cached online by ZoomEye. Of course, with the data provided in the ZoomEye history api, you can query the number of banners obtained by each scan regardless of whether you cover it or not.
