Widespread Weak Keys in Network Devices. We performed a large-scale study of RSA and DSA cryptographic keys in use on the Internet and discovered that significant numbers of keys are insecure due to insufficient randomness. We were able to remotely obtain the DSA private keys for 1. In experiments with several popular open-source software components.

ZMap is an open-source network scanner that enables researchers to easily perform Internet-wide network studies. With a single machine and a well provisioned network uplink, ZMap is capable of performing a complete scan of the IPv4 address space in under 5 minutes, approaching the theoretical limit of ten gigabit Ethernet. Check out our Getting Started Guide. Or go and Download ZMap. PhD Candidate, University of Michigan.
