Dharma, also known as CrySiS, is a long running ransomware family first observed in 2016. It operates as ransomware as a service, where developers lease the malware to affiliates who deploy it. A variant discovered in March 2021 appends the ".biden" extension to encrypted files. This article provides a technical analysis of Dharma, outlines its infection vector, describes its encryption workflow, and offers guidance for mitigation.

Technology failures are inevitable in operational technology (OT) environments. While prevention is essential, the ability to recover quickly is what ultimately protects operations. When OT systems fail, production stops and the costs of reduced production, missed deliveries and possible regulatory problems immediately begin to accumulate. Manufacturers, utilities and industrial operators need to be able to get systems up and running again as rapidly as possible after an incident.

Many organizations set remediation SLAs, but static severity-based timelines and manual tracking prevent them from meeting those deadlines in a way that meaningfully reduces risk. This article outlines how automated, risk-based SLAs connect timelines to real exploitability, exposure, and asset value, turning deadlines into reliable, measurable outcomes. Key takeaways from this article.
