Forescout Research Labs, in partnership with JSOF, disclosed a new set of DNS vulnerabilities, dubbed NAME:WRECK. These vulnerabilities affect four popular TCP/IP stacks ‘ namely FreeBSD, IPnet, Nucleus NET and NetX ‘ which are commonly present in well-known IT software and popular IoT/OT firmware. More than 180,000 devices in the U.S. and more than 36,000 in the UK are believed to be affected. If exploited, bad actors can use them to take target devices offline or assume control of their operations.
