.Nypd file extension ransomware (Nypd File Recovery Guide)

What is Nypd file extension

.Nypd file extension is a file extension that is used by the 232th version of the STOP ransomware to mark files that have been encrypted. Nypd ransomware is a malware that is created to encrypt the victim’s files, and then demand a ransom for decrypting them. Fortunately, there is a free Nypd File Decrypt Tool called STOP Djvu Decryptor that can decrypt encrypted files in some cases. In addition to this decryptor, there are several more methods that can help restore the contents of encrypted files. Read more about Nypd File Decrypt Tool, as well as how to remove Nypd ransomware, how to recover .nypd files and how to protect the computer from such ransomware below.

What is Nypd ransomware

Nypd ransomware is new version of STOP (Djvu) ransomware. According to security researchers, this version is not much different from previous versions of the STOP ransomware, such as Zwer and Kkll, which were discovered earlier. The Nypd ransomware is spread by websites offering to download freeware, key generators, activators, cracked games, torrents and so on.

Upon execution, Nypd creates a folder in the Windows system directory where it places a copy of itself and changes some Windows settings so that it starts up every time the computer is restarted or turned on. The virus collects information about the victim’s computer and then tries to establish a connection with its command server (C&C). If the connection has been established, then it sends information about the infected computer to the server, and in response receives the encryption key (the so-called ‘online key’) and additional commands and malware that must be executed on the victim’s computer. If the virus could not establish a connection with its command server, then it uses a fixed key (the so-called ‘offline key’).

The Nypd ransomware encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’, as described above). The virus tries to encrypt as many files as possible, for this it only encrypts the first 154kb of the contents of each file and thus significantly speeds up the encryption process. Nypd has the ability to encrypt files on all drives connected to the computer: internal hard drives, flash USB disks, network storage, and so on. It skips without encryption: files located in the Windows system directories, files with the extension .ini, .bat, .dll, .lnk, .sys and files with the name ‘_readme.txt’. The remaining files located on the victim’s computer can be encrypted. For example, the following file types may be the target of ransomware attack:

.accdb, .dxg, .sav, .blob, .snx, .wmd, .wcf, .1st, .asset, .wotreplay, .t12, .cfr, .xwp, .x3d, .jpeg, .ybk, .rim, .bay, .wb2, .p7c, .odb, .ff, .avi, .yml, .rw2, .forge, .wmo, .xdl, .kf, .csv, .crt, .png, .syncdb, .xlsm, .odm, .bkf, .wp4, .ptx, .wp5, .xyp, .hplg, .arch00, .dazip, .yal, .flv, .mlx, .gho, .arw, .fos, .ztmp, .xf, .m4a, .lvl, .zabw, .cer, .z3d, .ppt, .xlsx, .mpqge, .ai, .pptx, .vpp_pc, .bkp, .mrwref, .pfx, .crw, .pdf, .wps, .wbz, .7z, .epk, .icxs, .itdb, .bsa, .vfs0, .xmmap, .litemod, .wbm, .webdoc, .xmind, .p12, .wbmp, .p7b, .sr2, .psd, .wp, .wot, .wbc, .cdr, .xld, .jpe, .xpm, .xar, .wp7, .dba, .mdb, .svg, .sidd, .pak, .xlgc, .rofl, .x, .rgss3a, .ibank, .sis, .sb, .tax, .dcr, .wsc, .bc6, .wpe, .sum, .wma, .3ds, .d3dbsp, .wpb, .xbplate, .x3f, .py, .xll, .cr2, .nrw, .bc7, .dng, .dbf, .mddata, .itl, .mp4, .indd, .bik, .xyw, .mef, .cas, .kdb, .xlsx, .kdc, .xy3, .rar, .big, .sid, .xdb, .wpl, .wma, .gdb, .slm, .wbk, .qdf, .pem, .r3d, .xlsb, .wpd, .ltx, .wdp, .t13, .pdd, .wn, .odp, .map, .das, .zi, .orf, .fsh, .x3f, .rwl, .ws, .rb, .txt, .hkx, .wpw, .2bp, .wmv, .css, .db0, .desc, .wmv, .iwd, .3fr, wallet, .wri, .z, .mdf, .pef, .mcmeta, .esm, .odc, .srf, .wdb, .zip, .xml, .qic, .eps, .raw, .xls, .wps, .xxx, .re4, .xx, .fpk, .pst, .wire, .webp, .zdb, .sidn, .wp6, .pkpass, .pptm, .lbf, .wsd, .docm, .xls, .mov, .iwi, .w3x, .vtf, .m3u, .lrf, .upk, .m2, .tor, .rtf, .bar, .wm, .wpt, .wav, .apk, .wpg, .psk, .zdc, .hvpl, .sie, .ods, .wmf, .docx, .odt, .y, .vdf, .mdbackup, .doc, .dwg, .wsh, .ntl, .srw, .wgz, .jpg, .der, .ncf, .dmp, .xbdoc, .ysp, .wpa, .layout, .zif

Nypd encrypts file-by-file. Each file that has been encrypted will be renamed, the .nypd extension will be added at the end of its name. Thus, it marks all encrypted files. In every directory where there is at least one encrypted file, the virus places a file named ‘_readme.txt’. The file contains a message from the Nypd authors. An example of the contents of this file is given below.

This message says that all files on the computer are encrypted and the only way to decrypt them is to buy a key and a decryptor from the authors of the Nypd ransomware. That is, criminals demand a ransom for unlocking the victim’s files. The size of the ransom is $980, but if the victim is ready to pay the ransom within 72 hours, then its size is halved to $490. Attackers offer victims to verify that encrypted files can be decrypted. To do this, the victim must send them a small file to one of the email addresses specified in the ‘_readme.txt’ file. Of course, it is obvious that a single decrypted file cannot guarantee that after paying the ransom, the criminals will provide the victim with a working key and decryptor.

How to remove Nypd ransomware, Recover, Decrypt .nypd files

Security researchers confirm the words of the authors of the Nypd ransomware. All files with the extension ‘.Nypd’ are encrypted and thus cannot be read and used. The only way to decrypt them is to use the key and the decryptor. Fortunately, there is some good news. As we already reported above, the Nypd virus belongs to the STOP ransomware family, which means that you can use a Nypd File Decrypt Tool called “STOP Djvu decryptor” that is created by Emsisoft to decrypt the encrypted files for free. Even if the decryptor does not help, there are some alternative ways that can help restore the contents of the encrypted files. To learn more about decrypting files, simply scroll down to section ‘How to decrypt .nypd files’. Read the entire manual carefully.

How to remove Nypd ransomware

You can remove the Nypd ransomware and block its operation without downloading or starting any programs, just using the functions built into the Windows OS, since it is not difficult to do. But keep in mind that this ransomware most often penetrates the computer as part of a whole set of malware, which means that to be completely sure that there is no more malware on the computer, you need to scan the computer using antivirus or antimalware software.

It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Nypd ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Nypd ransomware, then let us know in the comments, we will try to help you.

To remove Nypd ransomware, use the steps below:

How to decrypt .nypd files

As we already reported above, files with .nypd extension are files that have been encrypted by the Nypd ransomware. Their contents will remain locked until decrypted using the decryptor and the key. Fortunately, there is a free Nypd File Decrypt Tool that can decrypt .nypd files. Below we provide instructions on where to download and how to use this decryptor.

To decrypt .nypd files, use Nypd File Decrypt Tool

• Download Nypd File Decrypt Tool from the following link.
  STOP Djvu decryptor
• Scroll down to ‘New Djvu ransomware’ section.
• Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
• Run decrypt_STOPDjvu.exe, read the license terms and instructions.
• On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
• Click the ‘Decrypt’ button.

Nypd File Decypt Tool is a free software that can decrypt files that were encrypted with an offline key, as Emsisoft found a way to determine this key. Unfortunately, files encrypted with an online key cannot yet be decrypted. The online key is unique to each infected computer, and at the moment there is no way to obtain this key. Of course, criminals have this key, but we do not think that paying a ransom is a way to decrypt .nypd files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.

This video step-by-step guide will demonstrate How to remove Nypd ransomware and Decrypt/Recover .nypd files for free.

How to find out which key was used to encrypt files

Below we will demonstrate how to find out the type of key with which files were encrypted. This is very important, since knowing the type of key you can understand if you can decrypt .nypd files for free using the Nypd File Decypt Tool. We recommend using the second method, as it is more accurate.

How to find out the type of a key using ‘_readme.txt’ file

• Open the ransom demand message (‘_readme.txt’ file).
• Scroll down to the end of the file.
• There you will see a line with the text ‘Your personal ID’.
• Below is a line of characters that starts with ‘0232’ – this is your personal id.

How to find out the type of a key using ‘PersonalID.txt’ file

• Open disk C.
• Open directory ‘SystemID’.
• Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the virus used to encrypt files.

The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Nypd virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.

Nypd File Decypt Tool : No key for New Variant online ID

If, when you try to decrypt .nypd files, the Nypd File Decypt Tool reports No key for New Variant online ID, then this means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Nypd authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.

Nypd File Decypt Tool : No key for New Variant offline ID

If during decryption of .nypd files the Nypd File Decypt Tool reports No key for New Variant offline ID, then this means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been found by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data. It is impossible to say exactly when the ‘offline key’ will be determined. Sometimes it takes several days, sometimes more. We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .zwer files.

How to restore .nypd files

As we mentioned above, in addition to using the Nypd File Decypt Tool, there are several more methods for recovering encrypted files. These methods do not require the use of a decryptor and a key, and therefore are suitable for all cases when the ransomware used an online key, and for the case when the ransomware used an offline key. It is very important to check your computer for malware before you try to recover encrypted files. You must be 100% sure that Nypd virus is completely removed. To scan your computer for ransomware, use free malware removal tools.

Recover .nypd files with ShadowExplorer

The Microsoft Windows has a feature called ‘Shadow Volume Copies’ that can help you to recover .nypd files encrypted by the ransomware. A small tool called ShadowExplorer will allow you to easily access the Shadow copies and restore the encrypted files to their original state. Unfortunately, the ransomware can delete these Shadow copies before it starts encrypting files. Therefore, if ShadowExplorer did not help you, then try another method, which is given below.

First, click the link below, then press the ‘Download’ button in order to download the latest version of ShadowExplorer.

After downloading is finished, open a directory in which you saved it. Right click to ShadowExplorer-0.9-portable and select Extract all. Follow the prompts. Next please open the ShadowExplorerPortable folder as on the image below.

Click File Formats button and specify file types to restore. You can to enable or disable the recovery of certain file types. When this is complete, press OK button.

Next, click Browse button to choose where restored files should be written, then click Search.

Count of recovered files is updated in real time. All restored documents, photos and music are written in a folder that you have chosen on the previous step. You can to access the files even if the restore process is not finished.

When the restore is done, press on Quit button. Next, open the directory where restored photos, documents and music are stored. You will see a contents as shown below.

All recovered personal files are written in recup_dir.1, recup_dir.2 … sub-directories. If you’re looking for a specific file, then you can to sort your recovered files by extension and/or date/time.

This video step-by-step guide will demonstrate How to recover encrypted files using PhotoRec.

How to protect your personal computer from Nypd ransomware

Most antivirus apps already have built-in protection system against the crypto malware. Therefore, if your machine does not have an antivirus program, make sure you install it. As an extra protection, run the HitmanPro.Alert. HitmanPro.Alert is a small security utility. It can check the system integrity and alerts you when critical system functions are affected by malware. HitmanPro.Alert can detect, remove, and reverse ransomware effects.
