Knight Ransomware Analysis
The Knight ransomware, the successor of the Cyclops RaaS, arrived in the cyber threat landscape in the summer of 2023, focused on targeting Windows, macOS, and Linux operating systems. The ransomware has promptly gained the spotlight by offering information stealers and a lite encryptor to lower-tier affiliates targeting smaller organizations. As its predecessor, Knight operated under the RaaS model, offering infostealers capable of uploading encrypted files to servers and commonly leveraging spam emails with malicious attachments.
Defenders have recently noticed a post on the RAMP forum attributed to a hacker with the alias Cyclops who is believed to be a representative of the Knight ransomware operators. The Knight 3.0 ransomware package for sale includes the control panel and the encryption (“locker”) mechanism. The seller asserts that the complete source code is proprietary and is written in Glong C++ . The upgraded ransomware version 3.0 was released in late fall 2023, boasting 40% faster encryption, an improved ESXi module to accommodate newer iterations of the hypervisor and a set of other enhanced capabilities.
The seller mentioned that preference would be given to reputable users who make a deposit and that the transaction would be facilitated through a transaction guarantor on either the RAMP or XSS hacker forum. The seller also stated that the source code would be offered for sale only once, indicating an effort to preserve the exclusivity and potentially significant value of the ransomware. Since the victim extortion portal of the ransomware operation is currently unavailable and the Knight ransomware campaign has been inactive for quite a while, threat actors might be considering ceasing malicious operations and liquidating their assets, which could be a potential reason for selling the ransomware source code.
The source code availability for sale on the dark web gives adversaries the green light to enhance their adversary toolkit and launch more cyber attacks. To gain a competitive advantage over offensive forces, defenders are striving to be proactive and continuously accelerate their threat detection and hunting velocity. With access to Uncoder AI, an advanced IDE for Detection Engineering, defenders can write detection code against emerging threats faster and smarter, rely on AI-generated recommendations and intelligence for streamlined threat research, and automatically translate detection algorithms across multiple cybersecurity languages.
