Data Center OT Flaws Could Help Hackers Kill Power and AC

Claroty Warns of Downtime, 'Devastating' Impact of Vulnerabilities in OT SystemsVulnerabilities in backup power devices and heating and cooling control systems widely used in data centers could enable remote cyberattacks and result in costly downtime and "devastating" operational impact, according to new research from OT security firm Claroty.

Recent advisories from U.S. federal authorities on vulnerabilities in certain operational technology devices underscore the potential security risks that many healthcare providers frequently underestimate, said Sila Özeren, a security research engineer at Picus Security.

Remote Access Tool Sprawl Increases OT Risks

Over-Deployment of Tools Raises Security and Operational ConcernsExcessive deployment of remote access tools in operational technology environments expands attack surfaces and creates operational challenges, warn security researchers from Claroty. Remote access tools are essential, but they introduce numerous potential vulnerabilities that threat actors exploit.

Nearly five dozen security vulnerabilities have been disclosed in devices from 10 operational technology (OT) vendors due to what researchers call are "insecure-by-design practices." Collectively dubbed OT:ICEFALL by Forescout, the 56 issues span as many as 26 device models from Bently Nevada, Emerson, Honeywell, JTEKT, Motorola, Omron, Phoenix Contact, Siemens, and Yokogawa

Nearly 60 holes found affecting 'more than 30,000' machines worldwide Fifty-six vulnerabilities – some deemed critical – have been found in industrial operational technology (OT) systems from ten global manufacturers including Honeywell, Ericsson, Motorola, and Siemens, putting more than 30,000 devices worldwide at risk, according to the US government's CISA and private security researchers. …
