Remove Rush ransomware (.remind Files Encrypted Malware)

Rush Ransomware is a file-encrypting ransomware, which will encrypt the personal documents found on victim’s computer using RSA-2048 key (AES CBC 256-bit encryption algorithm), appending the .remind extension to encrypted files. The Rush ransomware then displays a message which offers to decrypt the data if a payment of about 2 bitcoins, or approximately $1400 is made.

1. How did the Rush ransomware get on my computer?

The Rush ransomware is distributed via spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Rush ransomware.

2. What is Rush ransomware?

The Rush ransomware targets all versions of Windows including Windows 7, Windows 8 and Windows 10. This infection is notable due to how it encrypts the user’s files – namely, it uses AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key.

When the Rush ransomware is first installed on your computer it will create a random named executable in the %AppData% or %LocalAppData% folder. This executable will be launched and begin to scan all the drive letters on your computer for data files to encrypt.
Rush ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to .remind, so they are no longer able to be opened.

Files targeted are those commonly found on most PCs today; a list of file extensions for targeted files include:

.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt

Once your files are encrypted with the .remind extension, the Rush ransomware will create the DECRYPT_YOUR_FILES.TXT and DECRYPT_YOUR_FILES.HTML files ransom note in each folder that a file has been encrypted and on the Windows desktop.
These files are located in every folder that a file was encrypted as well as in the user’s Startup folder so that they are automatically displayed when a user logs in. These files will contain the information on how to access the payment site and get your files back.

When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.

3. Is my computer infected with Rush Ransomware?

When Rush ransowmare infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .remind extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When Rush ransowmare has finished encrypting the victim’s files, it will change the desktop wallpaper to an image that acts like a ransom note. It will also display a HTML ransom note in your default browser. These ransom notes include instructions on how to connect to the Decrypt Service where you can learn more about what happened to your files and how you can make a payment.

The messages displayed by this ransomware infection can be localized depending on the user’s location, with text written in the appropriate language.
This the message that the Rush ransomware may display:

All your files have been encrypted with Rush Ransomware
Your unique GUID for decrypt –
Send some 2 bitcoins on address –
After confirming the payment all your files can be decrypted.
If you do not make payment within 5 days, you will lose the ability to decrypt them AND ALL YOUR FILES HAVE BEEN DELETED
Make your Bitcoin Wallet on – After the payment, send the wallet from which paid and your unique ID to mail unransom@me.com
After receiving the payment, we will contact and give you decryption tools and far how to decrypt your files.

4. Is it possible to decrypt files encrypted by Rush ransomware?

No, at this time it’s not possible to recover the files encrypted by the Rush ransomware.

Rush ransomware is notable due to how it encrypts the user’s files – namely, it uses AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key. The RSA public key can only be decrypted with its corresponding private key. Since the AES key is hidden using RSA encryption and the RSA private key is not available, decrypting the files is not feasible as of this writing.

Brute forcing the decryption key is not realistic due to the length of time required to break an AES encryption key. Unfortunately, once the Rush encryption of the data is complete, decryption is not feasible without paying the ransom.
Because the needed private key to unlock the encrypted file is only available through the cyber criminals, victims may be tempted to purchase it and pay the exorbitant fee. However, doing so may encourage these bad guys to continue and even expand their operations. We strongly suggest that you do not send any money to these cyber criminals, and instead address to the law enforcement agency in your country to report this attack.

Restore the files encrypted by Rush ransomware with recovery software

In some cases, it may be possible to recover previous versions of the encrypted files using System Restore or other recovery software used to obtain “shadow copies” of files.

Option 1: Restore your files encrypted by Rush ransomware with ShadowExplorer

Rush will attempt to delete all shadow copies when you first start any executable on your computer after becoming infected. Thankfully, the infection is not always able to remove the shadow copies, so you should continue to try restoring your files using this method.

1. You can download ShadowExplorer from the below link:
   SHADOW EXPLORER DOWNLOAD LINK (This link will open a new web page from where you can download “ShadowExplorer”)
2. Once you have downloaded and installed ShadowExplorer, you can follow the below video guide on how to restore your files while using this program.
   

Alternatively, you can use the System Restore to try to recover the encrypted documents.

Option 2: Restore your files encrypted by Rush ransomware with File Recovery Software

When Rush encrypts a file it first makes a copy of it, encrypts the copy, and then deletes the original. Due to this you can use file recovery software such as:

• Recuva
  You can follow the below guide on how to use Recuva:
  
• EaseUS Data Recovery Wizard Free
• R-Studio
