These connections are part of an Internet-wide research study being conducted by IT security scientists at Paderborn University, Germany. This research involves making benign connection attempts to every public IP address. By measuring the entire public address space, we are able to study global trends in protocol security.
We will never attempt to exploit security problems, guess passwords, or change device
configuration. We only receive data that is publicly visible to anyone who connects to a particular address and port.
We are using the ZMap network scanner to facilitate some of these scans. ZMap has been used for dozens of peer-reviewed academic papers.
To have your host or network excluded from future scans conducted by us, please contact syssec-research-scans@lists.uni-paderborn.de and include the IP addresses or CIDR blocks you would like us to include in our denylist.
