Qilin is a well-documented ransomware-as-a-service (RaaS) operation that allows cybercriminal affiliates to launch targeted attacks in exchange for a share of the ransom payments. 

It employs encryption techniques combined with data theft as crippling leverage to extort victims, threatening the exposure of stolen data on dark web marketplaces if demands aren't met.

This breach could have severe repercussions for Hikari Seiko’s reputation, vendor and client relationships, and compliance standings. Beyond financial considerations, the incident highlights vulnerabilities that remain present even in advanced, technology-driven environments such as manufacturing.

The company has not yet commented publicly on the claims or provided updates regarding steps being taken to address the situation.

In October, a new Qilin variant called Qilin.B was identified. It is written in Rust, a programming language known for its resilience against reverse engineering.
