New analysis on operational know-how vulnerabilities by Armis discovered that 56% of engineering workstations have at the least one unpatched crucial severity.
As operational know-how (OT) merges with IT, vulnerabilities in operational tech techniques are a brand new menace, not least as a result of these networks contain management frameworks for industrial techniques, buildings and main infrastructure. The issue isn’t theoretical, given past attacks that exploited crucial safety vulnerabilities in Home windows techniques which are used to manage OT.
New knowledge from asset visibility and safety agency Armis exhibits the depth of the issue. The agency’s Asset Intelligence and Security Platform, which Armis mentioned tracks over three billion property, discovered crucial vulnerabilities in engineering workstations, supervisory management and knowledge acquisition (SCADA) servers, automation servers, management system historians and programmable logic controllers, that are additionally essentially the most weak OT and industrial management techniques.

Armis checked out all units on the Armis Asset Intelligence and Security Platform and recognized which varieties have the best severity danger elements and/or Widespread Vulnerabilities and Exposures (CVEs). Moreover, enterprise influence degree and endpoint protections had a weighted affect.
Soar to:
Engineering workstations lead the safety vulnerabilities record
Armis’ analysis discovered that engineering workstations had been the OT gadget that acquired essentially the most makes an attempt of assault within the trade previously two months, adopted by SCADA servers.
Engineering workstations
The research additionally discovered that 56% of engineering workstations have at the least one unpatched crucial severity CVE, and 16% are prone to at the least one weaponized CVE, revealed greater than 18 months in the past.
Uninterruptible energy provides
Third on the record of most-attacked OT are uninterruptible energy provides. In accordance with the agency, 60% of uninterruptible energy provide units have at the least one unpatched crucial severity CVE, which, as showcased with TLStorm, may probably lead criminals to trigger bodily injury to the gadget itself or different property related to it.
“UPS are widely used because control systems need a level of redundancy,” mentioned Carlos Buenano, a management techniques engineer and principal options architect at Armis. “UPS provides two things: It filters power [to shield devices against changes in power supply], and then makes sure it provides power to all the systems. The idea is to provide constant power feed across all devices and fill downtime in the power supply over a period of hours.”
UPS techniques are liable to safety vulnerabilities, he mentioned, as a result of they’re designed to not work together with any networks and don’t comply with particular safety requirements, corresponding to these developed by ISA/IEC, by which most units in management techniques meet some necessities with regards to safety.
“UPS systems have always been seen as isolated, but that is changing as ISA realizes that UPS and other devices are connected to a network and the reason is because throughout all plans every switch has to have a UPS to maintain power. And they all need to be monitored within an integrated system, such as a building management system,” mentioned Buenano.
Programmable logic controllers
Armis discovered that 41% of PLCs had at the least one unpatched crucial severity CVE. The agency mentioned that as a result of they’re legacy units present in all the things from elevators to braking techniques, compromised PLCs can disrupt central operations. The analysis discovered that these techniques are prone to excessive danger elements corresponding to end-of-support {hardware} and end-of-support firmware.
The agency mentioned one other set of units represents a danger to manufacturing, transportation and utility environments as they’ve at the least one weaponized CVE revealed earlier than January 2022. They embody:
- Barcode readers: 85% of which have at the least one CVE revealed earlier than January 2022.
- Industrial managed switches: 32%.
- IP cameras: 28%.
- Printers: 10%.
Risks in file-sharing protocols
Armis checked out gadget varieties and located that many are extra uncovered to malicious actions as a result of they’re utilizing the legacy SMBv.1 file-sharing protocol for Home windows — which had been exploited by Wannacry and the ExPetr (NotPetya) worms in 2017, the latter being the most costly cyberattack in historical past at $10 billion — in addition to older working techniques and plenty of open ports. The agency mentioned 4 out of the 5 riskiest units run Home windows OS.
Want for collaboration between OT and IT techniques and groups
The agency famous that OT industries comprise each managed and unmanaged units and complexity in location and distribution and that their convergence with IT has but to change into unified. With OT groups targeted on sustaining industrial management techniques, mitigating dangers to OT and making certain total integrity inside operational environments, extra IT-focused duties have been left apart.
Buenano mentioned the problem for IT/OT convergence is that they’re functionally opposed in some methods and function on very totally different networks.
“IT is designed to provide more applications to enable more uses. An OT network has one role, to communicate between devices and establish connections to achieve that task,” he mentioned. “They tend to clash because IT is focused on providing more products while OT’s aim is to ensure that the network is reliable and bandwidth stays available for applications.”

That mentioned, he defined that the convergence of IT and OT is significant as a result of the latter has been historically remoted from different networks and has fallen behind by way of system updates. “So they are conduits for threat actors. OT networks are designed for the long haul, with a ten-year operational lifespan, but using technology designed for 30 years,” he mentioned. “And vendors and customers in OT are known to work at a slow pace, so changes in the tech are very lagging.”
He mentioned convergence in IT/OT is about offering information from a safety and effectivity viewpoint and merging that into an OT setting, and {that a} advantage of convergence in IT and OT is that it creates value efficiencies related to not having to duplicate property.
