Loss of Productivity and Revenue

Tactic	Impact

Description

Adversaries may cause loss of productivity and revenue through disruption and even damage to the availability and integrity of control system operations, devices, and related processes. This technique may manifest as a direct effect of an ICS-targeting attack or tangentially, due to an IT-targeting attack against non-segregated environments. In some cases, this may result from the postponement and disruption of ICS operations and production as part of a remediation effort. Operations may be brought to a halt and effectively stopped in an effort to contain and properly remove malware or due to the Loss of Safety.

Procedure Examples

• Several transportation organizations in Ukraine have suffered from being infected by Bad Rabbit, resulting in some computers becoming encrypted, according to media reports.1
• A Conficker infection at a nuclear power plant forced the facility to shutdown and go through security procedures involved with such events, with its staff scanning computer systems and going through all the regular checks and motions before putting the plant back into production.2
• EKANS infection resulted in a temporary production loss within a Honda manufacturing plant.3
• While Norsk Hydro attempted to recover from a LockerGoga infection, most of its 160 manufacturing locations switched to manual (non-IT driven) operations. Manual operations can result in a loss of productivity.45
• NotPetya disrupted manufacturing facilities supplying vaccines, resulting in a halt of production and the inability to meet demand for specific vaccines.6
• The REvil malware gained access to an organization’s network and encrypted sensitive files used by OT equipment.7
• An enterprise resource planning (ERP) manufacturing server was lost to the Ryuk attack. The manufacturing process had to rely on paper and existing orders to keep the shop floor open.8

Mitigations

• Data Backup - Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise. Maintain and exercise incident response plans 9, including the management of "gold-copy" back-up images and configurations for key systems to enable quick recovery and response from adversarial activities that impact control, view, or availability.
