What is Powd virus?
Powd virus is a ransomware that attacks the victim’s computer by encrypting files and demanding a ransom for decrypting them. The ransomware attack can lead to data loss and financial losses. Powd encrypts files, renames them by appending the .powd extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “document.docx” will be renamed to “document.docx.powd”, a “image.jpg” file to “image.jpg.powd”, “invoice.pdf” to “invoice.pdf.powd”, and so on.

Powd ransomware in detail
Powd ransomware is a malware belonging to the STOP (Djvu) ransomware family. It encrypts files using a strong encryption algorithm. The virus uses a long key to encrypt files. This key is unique for each victim, therefore it excludes the possibility of using the same key to decrypt files on different computers. In some cases, when Powd is unable to establish a connection with its command and control (C&C) server, it uses a so-called “offline key”. This key is the same for all victims. And most importantly, security researchers have found a way to obtain this key.
Powd does not encrypt absolutely all files, as this will cause the computer to stop working. Therefore, it skips and does not encrypt Windows system files as well as files with the name ‘_readme.txt’ and files having the extension from the following list: .ini, .bat, .dll, .lnk, .sys. All other files on the victim’s computer will be encrypted. It makes no difference where the files are located, on a hard drive or cloud storage. If at the time of the ransomware attack a disk was connected to the computer, then all the files on it can be encrypted. In addition to the fact that Powd virus does not matter where the files are located, it also does not matter what type of files they are. Files of all common types can be encrypted, including the following:
.rwl, .xlk, .pptx, .dba, .psk, .1st, .bc7, .css, .ppt, .rgss3a, .yml, .wp4, .sql, .xlsx, .xar, .kdc, .xxx, .itdb, .x3f, .rtf, .dng, .wsd, .rim, .wps, .xlgc, .zdc, .avi, .wsc, .accdb, .odb, .wps, .ybk, .p7b, .m4a, .w3x, .xlsb, .yal, .z3d, .xll, .zip, .xlsx, .wdp, .bsa, .pfx, .rar, .iwd, .mddata, .mpqge, .sidd, .indd, .xwp, .fos, .mrwref, .hkx, .xld, .xml, .itm, .xls, .wot, .x3f, .wcf, .pdd, .3dm, .r3d, .fpk, .wotreplay, .fsh, .odc, .xlsm, .mcmeta, .hkdb, .mov, .rofl, .srw, .ibank, .snx, .wb2, .pst, .jpg, .icxs, .pak, .doc, .srf, .zip, .re4, .xdl, .erf, .lrf, .iwi, .odm, .wpw, .wm, .kf, .menu, .bar, .pkpass, .apk, .wbc, .wpd, .wpl, .desc, .rb, .vcf, .odp, .ws, .hplg, .ai, .vdf, .asset, .orf, .wire, .crt, .db0, .2bp, .t12, .t13, .3fr, .sis, .raf, .xf, .cr2, .lvl, .sb, .bkf, .zabw, .dxg, .mlx, .wpg, .mef, .lbf, .pdf, .hvpl, .bkp, .ztmp, .upk, .xmmap, .sr2, .odt, .mdf, .tor, .x3d, .wmo, .pef, .cas, .mp4, .wp7, .cdr, .xls, .wpe, .wmf, .wbd, .xdb, .xmind, .gdb, .ltx, .wp6, .dbf, .mdb, .wmv, .wbmp, .blob, .wmd, .7z, .d3dbsp, .das, .xpm, .xbdoc, .wbz, .ptx, .dazip, .x, .wdb, .wav, .p12, .vpk, .docx, .sav, .1, .der, .gho, .py, .ysp, .esm, .wbm, wallet, .wpb, .eps, .y, .qdf, .kdb, .crw, .flv, .sum, .m3u, .wgz, .xy3, .webdoc, .mdbackup, .rw2, .psd, .wpd, .wbk, .bik, .m2, .arw, .wp5, .webp, .z, .p7c, .wp, .litemod, .bc6, .jpe, .ff, .ntl, .dwg, .js, .zdb, .docm, .arch00, .sidn, .zif, .vtf, .csv, .xx, .pem, .itl, .sid, .jpeg, .zi, .syncdb, .vpp_pc, .0, .xbplate, .raw, .tax, .sie, .svg, .epk, .layout
When the process of encrypting the victim’s files is completed, all documents, databases, pictures and other files will be encrypted and thus the contents of these files will be locked. All encrypted files will receive a new name, which consists of their old name and the extension ‘.powd’ appended to the right. This means literally the following, if the non-encrypted file had the name ‘document.docx’, then after encryption it will be called ‘document.docx.powd’. The Powd ransomware drops files called ‘_readme.txt’ in each folder where there is at least one encrypted file. The contents of such a file are shown in the image below.
This file contains a message from the Powd authors. They inform the victim that the files on the computer were encrypted and offer him to buy a unique key and decryptor. According to them, this is the only way to decrypt files encrypted by the ransomware and thus restore access to their contents. The criminals demand $980 from the victim, but agree to take half the amount if the victim transfers it within 72 hours. Since the attackers understand that no one trusts their words, they offer the victim to decrypt one file for free. The main requirement for this file, it should be small and not contain important information. Nevertheless, all security experts warn victims of the Powd virus: successful decryption of one file does not guarantee anything at all. There is no guarantee that payment of the ransom will become a way to decrypt the files encrypted by the ransomware.
Text presented in the ‘_readme.txt’ file:
Don’t worry, you can return all your files!
All your files like pictures, databases, documents and other important are encrypted with strongest encryption and unique key.

Criminals do not lie, claiming that encrypted files cannot be decrypted without a key and decryptor. Security researchers confirm the words of the attackers said in the ransom demand message. The contents of the affected files are encrypted. But the files are not fully encrypted, but only the first 154kb of their contents. This can help the victims almost nothing, the only thing, since the files are not fully encrypted, victims can restore files from large ZIP archives. It is enough to simply rename the encrypted file by removing the .powd extension and open this file in the ZIP archiver, after which simply extract the desired file from the archive.
Fortunately, there is a free decryptor that can decrypt .powd files. This decryptor has one limitation, it can decrypt files encrypted with an offline key. If files are encrypted with an online key, then they cannot be decrypted yet, since there is no way to obtain this key. In the case when files are encrypted with an online key, victims can use alternative methods that do not involve the use of a key and a decryptor. These methods for recovering encrypted files are described in section ‘How to restore .powd files’ below.

How to remove Powd virus (ransomware)
You need to remove the Powd ransomware associated and its registry entries before proceeding to decrypt or restore encrypted files. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection.
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 Powd 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 Powd virus, then let us know in the comments, we will try to help you.
To remove Powd ransomware, follow the steps below:
Kill Powd virus
Press CTRL, ALT, DEL keys together.
Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Powd ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.
It is not difficult to detect a process related to the Powd ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Powd ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.
Disable Powd startup
Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.

How to decrypt .powd files
Files with the extension ‘powd’ are encrypted files. To decrypt them, you need to use a decryptor and a unique key. Fortunately, there is a free Powd File Decrypt Tool that can decrypt .powd files. This decryptor is compatible with all modern versions of the Windows OS and can decrypt files regardless of their size and type.
To decrypt .powd files, use Powd File Decrypt Tool
- Download Powd 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.
Powd File Decrypt Tool is a free software that can decrypt the encrypted files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the decryption key is in the hands of criminals and this key can not be determined. This does not mean that if your files are encrypted with an online key, then their contents are lost forever. Fortunately, there are several ways to recover encrypted files. These methods do not involve the use of decryption and therefore can be used in any case, no matter what key the ransomware used to encrypt files.
How to find out which key was used to encrypt files
Since STOP (Powd) decryptor only decrypts files encrypted with an offline key, each Powd’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.
Find out the type of 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 ‘0590’ – this is your personal id.
Find out the type of 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’, Powd 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.
Powd File Decrypt Tool : “No key for New Variant online ID”
If, when you try to decrypt .powd files, Powd File Decrypt Tool reports:
No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible
It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Powd 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.
Powd File Decrypt Tool : “No key for New Variant offline ID”
If, during decryption of .powd files, Powd File Decrypt Tool reports:
No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.
It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained 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.
If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .powd files.
This video step-by-step guide will demonstrate How to use STOP Djvu decryptor to Decrypt encrypted files.
How to restore .powd files
Fortunately, there are some alternative ways to recover encrypted files. Each of them does not suggest the use of a decryptor and a key, so these methods will suit all ransomware victims.
