Over 100 million IoT devices and servers are vulnerable because of 20-year-old TCP/IP stacks

In context: Security researchers at Forescout and JSOF have uncovered a set of nine vulnerabilities within four commonly used TCP/IP stacks.However, Forescout created an open-source script to help administrators track down vulnerable IoT devices and servers on the network.

Remote Device Fingerprinting: Clock leaks arising from either software on the host or application-level protocols on Whonix-Workstation ( anon-whonix ) allow a passive adversary to easily link anonymous and non-anonymous traffic to the same machine.
