Lateral movement is continued until privileges are recovered to obtain access to a domain controller.

This fact indicates that operators behind Ryuk malware carefully study each victim and perform expensive scouting and network mapping. Customization options from Chaos v4.0 are also unchanged, which gives the threat actor the following options: Death Note 13: How to Read describes Ryuk in the Death Note yonkoma as, of the characters, one who "may" be the character most resembling the equivalent character in the Death Note series. Figure of Ryûk, the most famous God of Death. He was the one who dropped the Death Note that Light Yagami retrieved from the human world before becoming Kira the main character of the anime Death Note™

The Relight films are a condensed version of the anime series. The premise of the films is that Ryuk tells the story to a fellow Shinigami. The last step is executed forever, as Ryuk will continuously attempts to discover new victims on the network and encrypt them. The Onyx group simply customized their ransom note and created a refined list of file extensions they wished to target. There is little other modification to differentiate it from any other samples built with Chaos v4.0.

Falcon Intelligence has medium-high confidence that the WIZARD SPIDER threat actors are operating out of Russia. Hermes was originally advertised on exploit[.]in . This Russian-speaking forum is a well-known marketplace for selling malware and related services to criminal threat actors. If Hermes was indeed related to STARDUST CHOLLIMA, it would imply that nation-state threat actors are selling their services on Russian-speaking forums, which is unlikely. It is not exactly obvious who stands behind this Ransomware. Some evidence and code similarities to another Ransomware called Hermes point towards a North Korean APT, Lazarus Group. However, this is not hard evidence, considering that a sample of Hermes could have fallen into the hands of another criminal and serve as a base for Ryuk's development.

Light was gonna use that thing to make himself god of the New World. Doesn't that interest you?” ( L: Change the WorLd) Ryuk does not encrypt files from within its own process memory space, but injects into a remote process. Before injecting into a remote process, Ryuk attempts to adjust its token privileges to have the SeDebugPrivilege . It takes no action if the adjustment of the token privileges fails. Before injecting into a remote process, Ryuk also calls CreateToolhelp32Snapshot to enumerate all running processes. If a process is found that is not named csrss.exe , explorer.exe , lsaas.exe , or is running under NT AUTHORITY system account, Ryuk will inject itself into this single process. By ensuring that the process is not running under NT AUTHORITY , the developers are assuming the process is not running under another account and therefore can be written to. Ryuk uses a combination of VirtualAlloc , WriteProcessMemory and CreateRemoteThread to inject itself into the remote process. Process/Service Termination and Anti-Recovery Commands As a passionate anime lover myself, with Death Note ranking among my all-time favorite series, I have had the pleasure of owning the SFC Figurine of Ryuk for some time now. Standing at an impressive 30 cm tall, this figurine not only captures the essence of Ryuk's character from Death Note but also satisfies the discerning tastes of dedicated anime enthusiasts like myself. Chaos started as a relatively basic attempt at a .NET compiled ransomware that instead functioned as a file-destructor or wiper. Over time it has evolved to become a full-fledged ransomware, adding additional features and functionality with each iteration.
