Death Note Anime Ryuk Figurine

Product Information

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. Compared to other families of ransomware, Ryuk has very few safeguards to ensure stability of the host by not encrypting system files. For example, many ransomware families contain extensive lists of file extensions or folder names that should not be encrypted (whitelisted), but Ryuk only whitelists three extensions: It will not encrypt files with the extensions exe , dll , or hrmlog . The last extension appears to be a debug log filename created by the original Hermes developer. It should be noted that absent from this list is sys (system drivers), ocx (OLE control extension) and other executable file types. Encrypting these files could make the host unstable. Early versions of Ryuk included the whitelisting of ini and lnk files, but these have been removed in recent builds. The following folder names are also whitelisted and not encrypted. There are two types of Ryuk binaries: a dropper (which is not commonly observed) and the Ryuk executable payload. Recovery of Ryuk droppers are rare, due to the Ryuk executable payload deleting the dropper when executed. Upon execution, the dropper constructs an installation folder path. The folder path is created by calling GetWindowsDirectoryW and then inserting a null byte at the fourth character of the path. This is used to create a string that contains the drive letter path. If the host operating system is Windows XP or earlier, the string Documents and Settings\Default User\ is appended to the drive letter path. If the host is Windows Vista or newer, the string users\Public\ is appended to the drive letter path. For Windows XP, an example folder path would be C:\Documents and Settings\Default User\ , and for Window Vista or higher, the path would be C:\Users\Public .

I was the whole thing, Taro. That was some pretty smart thinking. Hyuk hyuk hyuk. So how was it… the Land of the Dead?” ( Pilot chapter) The next steps taken by the injected payload are the same steps taken by the initial Ryuk ransomware invocation. Process and Service TerminationVariants of Chaos have been seen in-the-wild for a year now, and are likely used by multiple threat actors.

The first executable, bitsran.exe , is a dropper, and RSW7B37.tmp is the Hermes ransomware executable. The dropper’s goal is to propagate the Hermes executable within a network by creating scheduled tasks over SMB sessions using hard-coded credentials. The Hermes executable then encrypts files on the host. It is interesting to note that the compiler and linker for Hermes is different from the other executables. All of the executables except for Hermes were compiled with Visual Studio 10, with a linker of Visual Studio 10. Hermes, in contrast, was compiled with Visual Studio 9, with an unknown linker. It is interesting to see that there is yet another typo, this one is in the first command that prevents the command from running successfully (the letter ‘e’ is missing in the word “delete”). If the time stamps are correct, the two executables ( bitsran.exe and RSW7B37.tmp ) were compiled within four hours and three minutes of each other. Due to the short time frame of Hermes being bundled within an executable that was hard-coded with credentials of the FEIB network, Falcon Intelligence assesses that STARDUST CHOLLIMA likely had access to the Hermes source code, or a third party compiled and built a new version for them. Unlike other variants of Hermes, RSW7B37.tmp does not append the exported and encrypted AES key to the end of the file. Figure 5 is a file encrypted by Hermes with the exported AES key appended to the end of the file as a footer. Also, during forensic investigation of a network compromised by WIZARD SPIDER, CrowdStrike Services recovered artifacts with filenames in Russian. One file was named !!! files dlya raboty !!!.rar , which translates to “files for work.” Based on these factors, there is considerably more evidence supporting the hypothesis that the WIZARD SPIDER threat actors are Russian speakers and not North Korean. How CrowdStrike Can Prevent Ryuk This initial edition of Chaos overwrites the targeted file with a randomized Base64 string, rather than truly encrypting the file. Because the original contents of the files are lost during this process (seen in Figure 4), recovery is not possible, thus making Chaos a wiper rather than true ransomware.

1. Ryuk Ransom Notes

Ryûk is particularly curious and hates to be bored, which often leads him to visit humans and drop his Death Note to find some entertainment. He's also a fairly insightful Death god is very prankish. Shinigami's Eyes: Ryuk can see the real name and the remaining lifespan of a human simply by looking at them. He can also make a deal with a human being possessing a Death Note by giving him the same ability in exchange of half of the remaining lifespan of the human.

You're using the word 'destiny' for a woman again, Light. You always use a one patterned approach for women.” ( Tomorrow) Ryuk appears alongside Light as a non-playable story character for the crossover video game Jump Force.

Solutions on Ryuk Ransomware

Lateral movement is continued until privileges are recovered to obtain access to a domain controller. Like any Death God, he has a Death Note and can absorb the remaining life of any human he kills with the notebook. 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.

Process and service termination - Attempts to terminate processes and services that may interfere with its operationAlthough otherwise basic, Chaos-spawned malware had over a hundred targeted file-extensions that it would attempt to encrypt. Additionally, the malware had a list of files it would avoid targeting, including .DLL, .EXE, .LNK and .INI. These exclusions were likely there to prevent crashing the victim’s device by encrypting necessary system files.
