Bloody Valentine For Critical Infrastructure: EtherNet/IP Exploit Could Crash Devices

Security researchers made good on a promise to release new exploits for programmable logic controllers (PLCs). The exploits include one targeting a flaw in the implementation of the EtherNet/IP (Industrial Protocol) used in many IP-enabled PLCs. The security hole, if left unaddressed, could enable a remote attacker to crash or unexpectedly reboot the devices, which are critical components of almost every industrial – and critical infrastructure installation.


Ralph Langner is the closest thing to a rock star that you get in the Dockers and pocket-protector world of industrial control systems. The German researcher made headlines in 2010 as among the first security experts to analyze parts of the Stuxnet worm’s code devoted to manipulating programmable logic controllers by Siemens, and the first to explicitly link the Stuxnet malware with an effort to disable Iran’s uranium enrichment operation.
