Malware researchers have discovered a new ransomware, calling itself SNS Locker. The new enciphering malware encrypts files with .RSNSLocked file extension and uses a strong AES-256 encryption algorithm to encode a wide variety of files on the compromised computer. The ransomware then changes the wallpaper of the user with a random scary pic, notifying him to pay money to get his files back. The ransomware asks for 0.66 bitcoins which are approximately 300$.

SNS Locker – Distribution
Malware researcher Mosh at Nyxbone.com has researched the ransomware and has established that In order to be successfully distributed out into the open SNS Locker is believed to be spread out via an SNS Locker.exe and SNSLOcker2.exe files with the following parameters:
→ “File name: SNSLocker.exe / Size: 635.0 KB / VT
MD5: c3cd8168f96e89998cab52b436c24b7d

This executable may assume different names to be undetected manually, for example:
- {random name}.exe
- Svchost.exe
- Notepad.exe
- Your Confirmation.exe
- Receipt.exe
It may be spread out via game cracks, other keygens, activators, malicious email messages sent out as spam and even by malicious links that have come up as a result of an adware causing redirects to them, such as DNS Unlocker, for example.
SNS Locker Ransomware In Detail
Researchers at Nyxbone blog have established that the SNS Locker ransomware heavily modifies the computers it infects. For starters, once executed, the ransomware connects to the following C&C(Command and Control) IP address:
→ 5.9.82.18
The address appears to be based in Germany, and after SNS Locker connects to it, it immediately sends the following information from the infected computer:
- Customly generated 8 character ID of the victim. (For example – yas9yc92)
- Machine name.
- Username.
- Public IP address.
- MAC Address.
- Date.
The ransomware then begins to encrypt the files of the infected computer. It is reported to look for the following file types to encode:
→ .1pa, .3dm, .3g2, .3gp, .aaf, .accdb, .aep, .aepx, .aet, .ai, .ai, .aif, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bik, .bmp , .c, .cal, .cdr, .cdt, .cdx, .cgn, .class, .clk, .cmx, .cnt, .cpp, .cpt, .cpx, .cs, .csl, .csv, .cur, .dat, .db, .dbf, .des, .des, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .drw, .ds4, .dsf, .dwg, .dwg, .dxf, .efx, .eps, .eps, .fim, .fla, .flv, .fmv, .fpx, .fpx, .fx0, .fx1, .fxr, .gem, .gif, .gif, .h, .idml, .iff, .iif , .img, .indb, .indd, .indl, .indt, .ini, .inx, .iso, .jar, .java, .jpeg, .jpg”, .js, .lgb, .m3u, .m3u8, .m4u, .mac, .max, .mdb, .met, .mid, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .mx0, .nap, .nd, .pat, .pcd, .pct, .pcx, .pdb, .pdf, .pfb, .php, .pic, .plb, .plt, .pmd, .png, .pot, .potm, .potx, .pp4, .pp5, .ppam, .ppf, .ppj, .pps, .ppsm, .ppsx, .ppt, .ppt, .pptm, .pptx, .prel, .prn, .prn, .prproj, .ps, .ps, .ps, .psd, .psp, .ptb, .py, .qba, .qbb, .qbi, .qbm, .qbo, .qbp, .qbr , .qbw, .qbx, .qby , .qpd, .qsm, .qss, .qst, .qwc, .ra, .rar .raw, .raw, .rb, .rif, .rtf, .rtp, .sct, .sdf, .ses, .set, .shw, .sldm, .sldx, .sql, .svg, .svg, .swf, .swf, .tga, .tif, .tiff, .tlg, .tlg, .ttf, .txt, .txt, .txt, .v30, .vcf, .vob, .vsd, .vsd, .wav, .wav, .webm, .wi, .wk3, .wk4, .wma, .wmf, .wmv, .wpd, .wpd, .wpg, .wps, .xcf, .xla, .xlam, .xll, .xlm, .xls, .xls, .xlsb, .xlsm, .xlsm, .xlsx, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xpm, .xqx, .xqx, .zip Source:Nyxbone
The discovered files are encoded immediately with two of the most powerful ciphers in the world:
- AES cipher to encrypt the files on the compromised computer.
- RSA algorithm to encode the public AES key which is being sent to the criminals’ IP address.
The malicious software then changes the wallpaper image of the victim user to a terrifying picture, that may look like the following:

After this has been done, SNS Locker may automatically open a window with the ransom note and a method to decrypt the files by paying in BitCoin. It looks like the following:

SNS Locker also shows the user his own unique identification number which is most likely made to help the cyber-criminals identify multiple devices easily. Along with the number there is a button which may directly transfer the user to a payment page:

The payment page is rather simply created. It features the bitcoin address of the cyber-criminals in an electronic invoice which the user can pay online, from distance:

After the funds have been paid, the user may receive a link from the malicious domain of the cyber-criminals where he or she can find his private and public keys and click on the “Decypher” button to decrypt them:
SNS Locker – Conclusion, Removal, and Decryption Alternatives
The bottom line for SNS Locker is that it is basically a highly sophisticated ransomware which aims to basify the payment method for infected users, by being more “user-friendly”. This is a very effective method and it may have already made the cyber-criminals behind SNS Locker a lot of money. Despite that, malware researchers strongly advise hopeless users NOT to pay any ransom money due to the following possibilities:
- You fund the cyber-crooks to infect even more computers.
- You may not get your files back 100%.
To remove this ransomware effectively from your computer, we advise following the Manual or Automatic removal steps below. Experts also advise downloading a reputable anti-malware program which will automatically take care of the SNS Locker files for you.
Regarding file restoration, be advised that we have prepared some alternative methods in step “3” below that you may try while we investigate any decrypters which are publicly released and working. As soon as there is a solution, expect an update on this article’s web page.
