IpLogger is a basic Burp Extension that will make a request to https://api.ipify.org every time Burp is opened and will store the IP and date in iplogger.json.
iplogger.json can be found in the same directory as IpLogger.py is stored.
Log Example:
{
"date": "2022-12-27 19:23:54.039000",
"ip": "74.21.1.45"
}
{
"date": "2022-12-27 19:24:07.281000",
"ip": "80.61.9.22"
}The logs can be read with any text editor or using an JSON library like jq.
$ cat iplogger.json | jq -r .ip
74.21.1.45
80.61.9.22
