CloudSword Ransomware – Delivery
CloudSword ransomware might get delivered via different ways. The dropper for the payload file which initiates the malicious script for the ransomware can be found around the Web by the name Windows Update.exe, albeit its original name is cloudsword.exe. You can view the analysis of that executable file from the screenshot of the VirusTotal service, right here:
CloudSword ransomware might be using other delivery ways, such as spreading the payload file dropper through social media and file-sharing websites. Freeware applications which roam the Internet could be presented as useful but also could hide the malicious files of the virus. Don’t open files immediately after you have downloaded them, especially if they come from unverified sources, such as links and emails. You should always scan the files with a security tool before opening them, and check their sizes and signatures for anything that seems unusual. You should read the ransomware preventing tips thread in the forum.
CloudSword Ransomware – In Details
CloudSword ransomware is a cryptovirus, that is a variant of the open-source ransomware project HiddenTear. According to the malware researcher Jiri Kropac, the virus seems to be under active development. Soon, more versions of it might surface. When the CloudSword ransomware encrypts your files, it will append the same extension to all of them.
CloudSword ransomware adds a value to an entry in the Windows Registry to achieve persistence with auto-execution on each boot of the Windows Operating System. That entry is the following:
with the following value (or a similar one):
The ransom note with instructions is found inside the following file:
The not looks like the following:
That ransom note roughly translated into English, reads:
Because you violated Digital Millennium Copyright Act, all your important files have been locked
You must pay “+Network.amount+” bitcoin to the address below within five days, otherwise your unlock key will be lost forever
To unlocked your files and find instructions, go to
If you are using Tor, go to
If you don’t know how to get bitcoins, go to
Or email “+Network.email+”
Do not try decrypt yourself or use other tools
Here lists all encrypted files:
REMINDER: You have only FIVE days to make full payment
The developers of the CloudSword virus are probably still testing it as more versions of the ransomware are being released. You should NOT in any case contact the cyber criminals or pay them as nothing can guarantee you the recovery of your files. Giving money to these crooks will probably just support them financially and inspire them to do more criminal acts.
The CloudSword ransomware seeks to encrypt the following files:
→.accdb, .arch00, .bson, .d3dbsp, .DayZProfile, .dbfv, .divx, .docx, .epub, .forge, .hkdb, .hplg, .html, .ibank, .java, .jpeg, .layout, .mcgame, .mdbackup, .menu, .mpeg, .mpqge, .mrwref, .pptm, .rofl, .sc2save, .sqlite, .syncdb, .text, .unity3d, .vfs0, .wotreplay, .xlsb, .xlsx, .ztmp
The encryption algorithm that is used is believed to be AES and malware researchers say that the ransomware is a variant of the HiddenTear open-source project. Encrypted files will receive one and the same extension appended to them.
The CloudSword cryptovirus has a big possibility to delete the Shadow Volume Copies from the Windows operating system by using the following command in CommandPrompt:
→vssadmin.exe delete shadows /all /Quiet
