Cybersecurity business Kaspersky has recognized the primary factors contributing to sophisticated persistent menace (APT) attacks in industrial sectors.
The 1st of them, mentioned in a new report printed nowadays, is the absence of isolation in operational technology (OT) networks.

Kaspersky specialists have observed cases exactly where engineering workstations are linked to the IT and OT networks. This dependence on network configuration for isolation can be manipulated by experienced attackers, allowing them to regulate malware site visitors or infect seemingly isolated networks.
“In cases where the OT networks’ isolation entirely depends on the configuration of networking tools, seasoned attackers can generally reconfigure that tools to their edge,” explained Evgeny Goncharov, head of the industrial handle programs cyber unexpected emergency reaction crew at Kaspersky.
The human factor also stays a considerable driver of cyber-legal routines in industrial options, according to the report, with employees or contractors often becoming provided entry to OT networks without the need of suitable interest to information security measures.
Distant administration equipment, this kind of as TeamViewer or Anydesk that ended up meant to be short term might continue to run unnoticed, creating it quick for attackers to gain entry.

Kaspersky’s investigations also highlighted occasions wherever disgruntled staff or contractors with OT network accessibility have tried using to cause harm.
Insufficient protection of OT property even further amplifies these threats, as malware can unfold additional easily when security solutions have outdated databases, security components are disabled and there are as well several exclusions from scanning and safety.
Insecure configuration of security solutions also plays a substantial job in APT attacks, as does the absence of cybersecurity safety in OT networks and the lack of ability to preserve industrial workstations and servers up to date.
“In some circumstances, updating the server’s running technique may well require updating specialised software package […] which in flip requires upgrading the products – that all may perhaps be as well highly-priced. For that reason, there are outdated programs identified on industrial handle technique networks,” Goncharov additional.
“Surprisingly, even internet-facing programs in industrial enterprises, which can be somewhat easy to update, can remain susceptible for a extensive time. This exposes the operational technology […] to attacks and serious dangers, as real-environment attack eventualities have demonstrated.”
The Kaspersky report will come a couple of months after a different exploration analyze from the corporation suggested two out of each individual five (40.6%) OT pcs made use of in industrial configurations ended up afflicted by malware in 2022.
