StorageCrypter — ransomware that encrypts data on the Cloud and targets South Korea

StorageCrypter virus illustration
StorageCrypte is a ransomware that encrypts data and demands for 0.4 or 0.8 in Bitcoin.

StorageCrypter ransomware is a typical file-locking virus that functions like any other ransomware: scans the infected computer for files, uses the encryption algorithm to lock up files, and then demands ransom payment in digital currency for the access to personal victims' data. Except for this time, the crypto-malware can encode files stored on the network like Cloud. Victims reported being provided with a _READ_ME_FOR_DECRYPT.txt ransom note and asked to pay 0.4 BTC for recovering .locked data in 2017. However, almost a year later this threat came back with the new read_me_for_recover_your_files.txt ransom note and Leviathan13@protonmail.com contact email. Additionally, crooks demand twice as much ransom payment than previously. StorageCrypter is extremely active right now and found to be targeting South Korean users by utilizing SambaCry exploit kit.

Elimination Use Reimage for StorageCrypter ransomware removal 

The attack of this ransomware starts when a virus scans the system and indicates that the device was or was not encrypted before. After that, is exploits the typical command for a file-encrypting malware and locks various user files using AES and RSA encryption methods. 

This cyber threat started to attack in November 2017, and then researchers reported that this ransomware targeted My Cloud accounts which were exposed online. Ransomware can target different files and your photos, documents, music or even databases can be locked and useless. After the modification, this ransomware places .locked file extension and this appendix indicates which data was encrypted.

 StorageCrypter ransomware affects the following files:

3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip.

The victims of StorageCrypter are encouraged to contact the criminals via JeanRenoAParis@protonmail.com email address to receive a decryption tool after they make a payment. Besides, they try to gain victims' trust by offering free decryption of one file. The document must not contain important information and be less than 2 MB. This test decryption is suggested on the newer ransom note too. 

StorageCrypter
StorageCrypter is a virus that uses SambaCry exploit to spread around the world.

Note that RSA and AES encryption is widely used to protect the secrets of Armed forces[1]. It gives the ability for the crooks to manipulate their power and you have no guarantees that they will keep their promises. Instead, they can ask for even more money once you make the transaction. You should remove StorageCrypter ransomware immediately and try alternative recovery methods to retrieve your corrupted data.

After the successful encryption process developers behind the cyber infection want to get money so the text file _READ_ME_FOR_DECRYPT.txt or read_me_for_recover_your_files.txt, depending on the version, appears on every folder containing encrypted data. Both of these files are ransom notes and inform the victim about the cyber attack.

_READ_ME_FOR_DECRYPT.txt file of StorageCrypter ransomware informs how to retrieve the corrupted data:

The ransom note states that there is no other possibility to decrypt files and you need to write them via Leviathan13@protonmail.com email but we do not recommend to contact these cybercriminals. This communication can lead to permanent data or money loss. 

Also, this is a product of crypto-extortionists that have various techniques for spreading their malware. One of the methods used in the first StorageCrypter ransomware attack was SambaCry exploit kit. This is a Linux Samba vulnerability that allows attackers to exploit command shell in order to download or run various commands on the infected system.

This SambaCry exploit is a version of EternalBlue. This exploit addresses a CVE-2017-7494[2] vulnerability that allows attackers to exploit malicious code on the system remotely. The particular vulnerability gives an ability to upload a shared library to a folder and execute the malicious code directly.

Ransomware can be spread by other malware like trojans and other silent intruders. These infections come from insecure spam attachments or deceptive ads. So there is a possibility that you have other programs or files with possibly malicious goals. These are the files/programs related to StorageCrypter ransomware that various anti-virus indicate as malicious:

  • Trojan.Elf.SIU
  • LINUX/Dldr.Agent.roatu
  • ELF/SambaShell.A
  • Linux.DownLoader.644
  • TR/Comame.A.348.1
  • Win32:Virut-AQM
  • Win.Trojan.Agent-544816
  • LINUX/Agent.bfsbw
  • HEUR:Trojan.Linux.Agent.fb
  • HEUR:Trojan.Linux.Agent.fb[3]

Reimage is the best programs to finish StorageCrypter removal quickly. Also, you can check the elimination guide below or decryption steps which are attached at the end of this article too. If you follow steps attentively, you might be able to restore at least a few of your encrypted files.

Ransomware spreading techniques 

We are aware that most victims of StorageCrypter do not know how the crypto-malware infiltrated on their computer. According to the experts from LosVirus.es[4], the typical ransomware spreads via:

  • Trojan Horses;
  • Malspam campaigns;
  • Malware-laden ads;
  • Exploit kits.

This ransomware is known for spreading via exploit kits. In particular, SambaCry that is related to Linux Samba. This method allows the hacker to execute that command shell and download ransomware directly to the infected system. 

Additionally, crooks send malicious attachments which look like genuine invoices from DHL or UPS worldwide. As a result, people get tricked to open them and start an automatic installation of the ransomware. Likewise, you are advised to stay away from any suspicious programs, messages or advertisements which are not offered by authorized developers. 

StorageCrypter virus elimination process

If you do not want to peril your computer, remove StorageCrypter ransomware automatically. It is the safest option you can choose since ransomware tends to bring other malicious programs alongside. The best example would be Trojans which detect and exploit your system vulnerabilities to leave backdoors for future malware infiltration[5]

Inexperienced computer users are not able to detect StorageCrypter components since they disguise under legitimate operating system processes. Trying to eliminate the ransomware manually can end up harming your computer even more. Therefore, we strongly recommend not to perform a manual termination.

Instead, pick Reimage or other[6] reputable security application to start StorageCrypter ransmoware removal. They will detect all elements of the ransomware and other unwanted programs. Shortly after, you will be able to continue to data recovery. Feel free to check the detailed instructions below which will present you alternative methods on how to retrieve your files.
