Ransomware Group Targets HAWITA Group

Ransomware group Qilin has targeted the HAWITA Group, but has not disclosed any other information. The HAWITA group is a producer of peat moss, substrates, planter pots, and Easypot. It is a globally operating company with more than 400 employees at present, eight production sites, and more than 4,500 ha of moor area in Germany and Baltic States.

Introduction to Qilin Ransomware

Qilin (aka Agenda) is a RaaS (Ransomware-as-a-Service) operation that first emerged in July of 2022. It is written in the Go and Rust programming languages and is capable of targeting Windows and Linux systems. Rust is a secure, cross-platform programming language that offers exceptional performance for concurrent processing, making it easier to evade security controls and develop variants to target multiple OSs.

Qilin's Attack Tactics

Qilin operators are known to exploit vulnerable applications including Remote Desktop Protocol (RDP). Each Qilin ransomware attack employs tactics such as altering the filename extensions of encrypted files and terminating specific processes and services. The utilization of Rust as the ransomware's foundation proves particularly effective due to its evasive nature and inherent complexity, allowing for seamless customization across various operating systems such as Windows, Linux, and others. Notably, the Qilin ransomware group can generate samples for both Windows and ESXi versions.

Qilin's Dark Web Presence

Qilin promotes its ransomware on the dark web, utilizing a proprietary DLS (Dedicated Leak Site) that contains distinctive company identifiers and leaked account information, as uncovered by experts from Group-IB Threat Intelligence.

Double Extortion Technique

The operators behind Qilin employ a double extortion technique, whereby they not only encrypt a victim's sensitive data but also exfiltrate it. Subsequently, they demand payment for a decryptor and insist on the non-disclosure of stolen data even after the ransom has been paid. Qilin ransomware features multiple encryption modes, all under the control of the operator.
