A virus pretending to be the CSTO, called Cry ransomware had been reported to use RSA-4096 and the .cry file extension to encrypt the files of computers infected by it. The virus wants it’s victims to pay the different sum, depending on the files. The ransom payoff which victims should pay the cyber criminals is usually in the range of 0.27 to 1.14 BTC (BitCoin). After the encryption has been performed, the cyber criminals give users a deadline of 100 hours to pay the ransom or they will double the amount. Users are strongly advised not to pay any ransom money set by Cry Ransomware in case they have been attacked. Instead, we recommend reading this article to learn how to neutralize this threat and attempt to restore your files.

Cry Ransomware – How It Spreads
For it to infect more and more users on a daily basis, Cry ransomware aims to slither files that pretend to be original Microsoft Office, Adobe Reader or other types of documents or legitimate file formats. Such files may be redistributed on shady websites, uploaded as fake setups or fake documents that the user may be surfing the web for. They may also be pushed aggressively as a part of massive spam e-mail campaigns that replicates the Cry Ransomware’s files as attachments to convincing messages and topics of the e-mail to fool inexperienced users. Here are some examples of e-mail topics that may carry a malicious attachment or web link both containing Cry Ransomware:
- “Your Purchase Is Complete.”
- “Your Debit Card Has Been Closed.”
- “The funds have been withdrawn.”
Cry Ransomware – What Does It Do
As soon as Cry Ransomware has infected your computer, the virus may begin to drop it’s payload. This may happen in several different ways:
- By directly connecting to a remote host and downloading the malicious file (s).
- By directly having the payload on your computer.
- By having other malware such as Trojan.Downloader on your computer that can download the files.
- By activating a .js(fileless ransomware) file.
As soon as it has been activated on your computer, the Cry virus may drop the following files:
- !Recovery_{user id number with letters}.txt
- !Recovery_{user id number with letters}.html
- {malicious payload}.exe
All of the files may have copies in the %Startup% folder of windows or may have values strings in the following Windows Registry keys to run on system startup:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
As soon as this has been done and the Cry virus is activated, it may immediately create a folder, named “old_shortcuts” on your desktop where it moves the files it encrypts.
The Cry virus is pre-programmed to encrypt approximately 650 file types. Here is a small portion of the files it looks for and encrypts:
→ .#vc, .$ac, ._vc, .00c, .07g, .07i, .08i, .09i, .09t, .10t, .11t, .123, .13t, .1pa, .1pe, .2011, .2012, .2013, .2014, .2015, .2016, .2017, .210, .3dm, .3ds, .3g2, .3gp, .3me, .3pe, .500, .7z, .aac, .aaf, .ab4, .ac2, .acc, .accd, .ach, .aci, .acm, .acr, .aep, .aepx, .aes, .aet, .afm, .ai, .aif, .ami, .arc, .as, .as3,.asc, .asf, .asm, .asp, .asx, .ati, .avi, .back, .bak, .bat, .bay, .bc8,.bc9, .bd2, ., .h, .h10, .h11, .h12, .hbk, .hif, .hpp, .hsr, .html, .hts, .hwp, .i2b, .iban, .ibd, .ico, .idml, .iff, .iif, .img, .imp, .indb, .indd, .indl, .indt, .ini, .int?, .intu, .inv, .inx, .ipe, .ipg, .itf, .jar, .java, .jnq, .jp2, .jpeg, .jpg, .js, .jsd, .jsda, .jsp, .kb7, .kd3, .kdc, .key, .kmo, .kmy, .lay, .lay6, .lcd, .ldc, .ldf, .ldr, .let, .lgb, .lhr, .lid, .lin, .lld, .lmr, .log, .lua, .lz, .m, .m10, .m11, .m12, .m14, .m15, .m16, .m3u, .m3u8, .m4a, .m4v, .mac, .max, .mbsb, .md, .mda, .mdb, .mdf, .mef, .mem, .met, .meta, .mhtm, .mid, .mkv, .ml2, .ml9, .mlb, .mlc, .mmb, .mml, .mmw, .mn1, .mn2, .mn3, .mn4, .mn5, .mn6, .mn7, .mn8, .mn9, .mne, .mnp, .mny, .mone, .mov, .mp2, .mp3, .mp4, .mpa, .mpe, .mpeg, .mpg, .mql, .mrq, .ms11, .msg, .mwi, .mws, .mx0, .myd, .mye, .myi, .myox, .n43, .nap, .nd, .nef, .nl2,.nni, .npc, .nv, .nv2, .oab, .obi, .odb, .ode, .odg,.odm, .odp, .ods, .odt, .oet, .ofc, .ofx, .old, .omf, .op, .orf, .ost, .otg, .otp, .ots, .ott, .p08, .p12, .p7b, .p7c, .paq, .pas, .pat, .pcd, .pcif, .pct, .pcx, .pd6, .pdb, .pdd, .pdf, .pem, .per, .pfb, .pfd, .pfx, .pg, .php, .pic, .pl, .plb, .pls, .plt, .pma, .pmd, .pnq, .pns, .por, .pot, .potm, .potx, .pp4, .pp5, .ppam, .ppf, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .pr0, .pr1, .pr2, .pr3, .pr4, .pr5, .prel, .prf, .prn, .prpr, .ps, .psd, .psp, .pst, .ptb, .ptdb, .ptk, .ptx, .pvc, .pxa, .py, .q00, .q01, .q06, .q07, .q08, .q09, .q43, .q98, .qb1, .qb20, .qba, .qbb, .qbi, .qbk, .qbm, .qbmb, .qbmd, .qbo, .qbp, .qbr, .qbw, .qbx, .qby, .qbz, .qcn, .qcow, .qdf, .qdfx, .qdt, .qel, .qem, ..vbs, .vcf, .vdf, .vdi, .vmb, .vmdk, .vmx, .vnd, .vob, .vsd, .vyp, .vyr, .wac, .wav, .wb2, .wi, .wk1, .wk3, .wk4, .wks, .wma, .wmf, .wmv, .wpd, .wpg, .wps, .x3f, .xaa, .xcf, .xeq, .xhtm, .xla, .xlam, .xlc, .xlk, .xll, .xlm, .xlr, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xpm, .xqx, .yuv, .zdb, .zip, .zipx, .zix, .zka (and others…)
This vast array of files, if detected, are encrypted with a very strong RSA-4096 encryption cipher, the decryption for which may take a lot of time, if the computer decrypting it doesn’t break by then.
The scrambled files cannot be opened by any software and contain the .Cry file extension, for example:

Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Cry Ransomware on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Cry Ransomware there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Cry Ransomware
Step 5: Try to Restore Files Encrypted by Cry Ransomware.
