Q: what are encrypted files ?? do we have any way to encrypt or decrypt and file ??

Hello,

1) What are encrypted files and how do we know which files are encrypted and which are not.
2) i know its against the TSF rules to discuss anything related to password recovery or anything like that but just curious to know when anybody forget the password and if they are able to remove or change the password , would it affect encrypted files in anyway ??

3) Is their any way we can make any file encrypted or if we need to how we can remove encryption of any file.

Thanks

Preferred Solution: what are encrypted files ?? do we have any way to encrypt or decrypt and file ??

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: what are encrypted files ?? do we have any way to encrypt or decrypt and file ??

An encrypted file or folder is a file or folder that only someone with the appropriate permissions can view.

If you are the administrator of a computer with folders or files on it that you have created then you can encrypt them and only someone with the appropriate permissions i.e you and anyone else you give permission to can see and view the contents of that folder or file.

You can only do things with the file if you created it or are the administrator or have the appropriate permissions.

I have an odd case. It appears to me that I have signs of a encryption type virus, but there is no ransom note to be found anywhere.
 
Symptoms - 2 shared drives on a server where all file modified dates are changed to yesterday and are all unable to be opened. At the same time, other shared drives on this server have no issues whatsoever. Also, there are no hardware/software problems that I can detect on the machine.

A few days ago, I noticed a popup saying computer wanted to reboot and would if I didn't postpone it. I wasn't doing anything, so I went ahead and did it. The windows updates (running Windows 7 Professional 64-bit) applied and I got back to the desktop. Adobe put up a box saying there was an update for it too, so I clicked on it. Before I could start it though, I got a windows box that said "Encrypting File System" and told me to backup my file encryption certificate and key. After some searching on google with a different computer, I found that this sometimes come up even if you have never encrypted anything as I have not. So I went ahead and let it save the key to a flash drive. I did the cipher /u command to find if any files were encrypted. It found thousands of files in 7 directories. Mostly pictures (.jpg) on the second hard drive and they weren't viewable.

Error: "Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location."

Filenames were green in explorer. So I tried using the backup of the encryption certificate and key. It seemed to restore just fine, but all the files were still encrypted. I tried the decript command "cipher /d" but that wanted to either be in the directory or specify the directory/filename and the list from the /u just flew by and would only scroll back so far.

After some more searching, found a .vbs script to find all the encrypted files... Read more

A:decrypt files files that I didn't encrypt

Well, from what I've been able to find and try, looks like those last two directories are simply not recoverable. Since I didn't encrypt them in the first place, I don't seem to have a key for it.

So, for the future...
What made it encrypt those directories so I can not do it again?
What should I do now to prevent problems like this again? Just backup my encryption key and try and remember where I backed it up to? The current one should be good for a while. One of the many things I tried was extending the expiration date to 2113.

A few months ago, I performed a repair of Windows XP Pro SP2 to recover from some issues (never figured out what, though).



Recently, I tried to access a file that I had encrypted (using NTFS encryption through Windows). I found that I couldn't open, decrypt, or move the file to a FAT32 flash drive (access denied). Thinking that the repair install had done something to the encryption, I logged on as the Administrator and attempted to take ownership of the file, but Access was denied again. I then attempted to edit the file permissions and was able to add all users to the list of accounts allowed to access the file. But when I tried to access it, access denied.

Thinking perhaps that the file was corrupted, I deleted it and restored a copy from a backup made in December (my backups only go back 2 weeks). The restore was successful but the probel remained. So, I tried to restore the file again, but this time to a FAT32 flash drive with the settings set so that security descriptors would not be restored (I use Windows built in backup utility). The restore failed. I tried the same thing again but to an NTFS drive but it failed again.

Can anyone help me?

A:Encrypted File Won't Decrypt

You might try cipher from a command line using the /d switch.The encrypted file needs to be sitting on an ntfs volume. I believe the read only attribute may need to be removed as well. More on it here. Click the "cipher" link on that page.

A:decrypt encrypted files error

Hello Shawn, and welcome to Seven Forums.

If you didn't backup the EFS certificate before installing Windows 8.1 and importing the certificate afterwards, then I'm afraid that you lost access to the encrypted green file.

If you like, you can just delete them.

I was infected with the CTB locker. My IT cleaned my computer from it but my files on the computer are still encripted, or at least it looks like that.
I opened the http://w7yue5dc5amppggs.onion/ page with Tor Browser as I was instructed in the message received with the CTB locker and here got the option to decrypt 1 encryted file before I pay 2,5 Bitcoins to convince me that decrypt is working. So I have uploaded 1 file with the extension "ingoauj' (all my infected files have this extension) but I received the message that this file is not encryted.

A:decrypt CTB locker encrypted files

The newest variants of CTB Locker typically encrypt all data files and rename them as a file with a 6-7 length extension with random characters. The newer variants also do not always leave a ransom note if the malware fails to change the background, like it generally does. Compounding matters, the newer CTB-Locker infection has been seen in combination with KEYHolder, Torrent Locker (fake Cryptolocker) or Cryptowall ransomware. Unfortunately, there is still no known method of decrypting your files without paying the ransom and with dual infections, that means paying both ransoms.A repository of all current knowledge regarding this infection is provided by Grinler (aka Lawrence Abrams), in this tutorial: CTB Locker and Critroni Ransomware Information Guide and FAQThere is also an ongoing discussion in this topic: CTB Locker or DecryptAllFiles.txt Encrypting Ransomware Support & Discussion. Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion.ThanksThe BC Staff

Hi all,
Thanks in advanced for your advises :D!
The situation is as follow:
1st part - UNABLE TO ENCRYPT
- Our AD server is 2012 R2 v. 6.3 Build 9600.
- Users below are using Windows 7 Professional and joined domain.
- I created new certificate in Public Key Policy/ Encrypting File System as Administrator and push down to the domain group
- We started doing encryption EFS for our users...most are ok, except one PC A.
- User A who is using PC A we cant encrypt his files. Pop up is 'The Parameter is Incorrect' when doing EFS encryption.
- if User B log in to PC A, his files on PC A can be encrypted. If user A log in to user B PC, his file can be encrypted as well.

- So seems like issue is only at PC A and only with user A
so my 1st Question: Why is this happening and how to prevent this? (possibility is user profile corrupted but why and where it's corrupted?

2nd Part - UNABLE TO USE ENCRYPTED PST FILES

- I decided to copy all User A files (including Outlook pst), delete his profile and recreated new profile with same name
- Copy all his file over, set up outlook with old pst file again. And start doing encryption include outlook files.

- Encryption went smoothly.
- Next day (or may be when user restart etc..) when open, Outlook prompt Access denied for his pst file.
- All other files that was encrypted together with pst files (doc, xls etc.) are able to open and use normally
- At the same time, one more user reported having this Outlook access denied... Read more

Hey Everyone,

I am having a huge issue at the moment where our shared files are being encrypted by a virus/trojan. This incident started this morning and was discovered in the afternoon but unfortunately most of the files (around 20-40 GB) were encrypted by this virus. The infected files are Pictures, Excels, Words and PDFs and the processes that likely were responsible for the encryption were shutdown and moved to a temporary folder.

The suspicious processes that were running were:
hovynqoruhup.exe
ynecyc.exe
heap.exe
Heogbawcyhobbb.exe

Using ESET Anti-Virus, they are identified as:
Kryptik.BORN
Kryptik.UDL
Kryptik.BOSI

My question is - how can get my files back?? (I do have some copies of the original files before encryption)
- Are there decrypters out there for these viruses?

I believe this is something that many of you guys here have seen and experienced, if you could share your solutions I would very much appreciated.

Thanks!

one with a VARIABLE name, and Dirty Decripter.
The first disabled Task Manager and all the ways to reactive it, but i was able to delete every copy it made of himself in my computer.
I removed also Dirty Decrypter, and actually, there aren't more than 50% of .doc/.xls files encrypted by it.
Now, there is only one doc and only one excell file that i need, and they are encrypted. After that, i looked around in the net to find some decrypters, but no one of them worked correctly.
I'd like to know if there is a working decripter to solve the problem. If not, and if in this forum there are some developers, i think that can be helpful somethig i have:

How do I get back the files that were in an encrypted folder in Windows XP? I went to the User I used to encrypt them (right click on folder->encrypt folder and subfolders) and undid that option, but even though the folder and subfolders are no longer listed in green color (the color of encrypted folders) the files themselves are still gone, just the folders themselves remain, but no files at all that used to be visible in those folders. I hate encryption. I never thought it meant "hide these files from everyone, including ME." It's so stupid. How do I decrypt my folders, or, perhaps more accurately, how do I decrypt the files that used to be visible inside the folders and subfolders in the previously-encrypted folder? I even did the lengthy thing related to Certificates and still the files themselves are hidden from me. And they're not simply "hidden files" because I tried that option in options->View but it didn't do the trick. There's gotta be another way.

Then few days earlier i formatted drive (Cand upgraded my system to windows 8.1-64bit.
But I got worried when i saw that i m unable to access my all photos and videos that i encypted.It turned green.I could not even move or view them.

Then i installed windows 7 ultimate-64 bit thinking might this would help.But in vain.Presently I m on windows7-64bit os.

I tried to change the owner permissions but i was unable to.It said access denied.Maybe its asking for the owner that was on windows8-64 bit,(earliest one on which i encrypted the files).And now the owner has changed due to change in os and the thumbprint too.

Sir those files are really important for me.what can i do to get them back
 

A:Cant Decrypt 'encrypted files on previous version of Windows' after a format

As stated in this guide, if you don't have the key you will not be able to access the encrypted files.

http://windows.microsoft.com/en-GB/windows-8/bitlocker

The encryption system is extremely secure, if it wasn't it would serve no purpose and there is no way to break it without the encryption key.

Encryption would generally only be used for high risk information like banking details or anything you would not want an unauthorized user or a hacker to get access to. Photo's and movies are better just backed up to DVD's to keep them safe. Hard drives will always fail in time, so you should only leave data on your system that has not been backed up if you don't mind loosing it.

I have not attempted to follow these instructions. The second file is called Thumbs and is a Data Base file which I have never opened. I have attached a copy of the first file to this post. Data Base files aren't permitted as attachments.
 
These files are all dated 5 July 2013 at various times in the afternoon and evening (British Summer Time).
 
I did not notice the problem had occurred until Sunday 7th July - I did not start up my computer at all on 6th July.
 
As far as I can tell all my Excel and Word files have been encrypted on all my hard drives. Many of the tens of thousands of .jpg files on all the hard drives have also been rendered unreadable, but not all of them.
 
I am seeking help to find a method of restoring all my files - many years of photography are at stake!
 
Contents of my DDS log follow. Thanks to anyone who can help.

I expect this is going to be basic to the most of you but here goes. I am running Win 7 on my main laptop and XP on my spare. I am using a Freecom Usb hard drive to transfer files. When I go from Win7 to XP I find that the text on the files is green and can't be opened in XP. If I go back to Win 7 I find that they are encrypted and I have to decrypt to transfer them. How can I stop this happening please?
Also can I link the computers up with each other to save transferring in the above manner? Thanks in anticipation. Peter.

A:Encrypt decrypt, that is the question

"Green" files are encrypted, password protected, etc...

If you have bitlocker on or other HDD/ file encryption on Windows 7, that may be the issue.

Did you have a password before you formatted? Try using that same password and decrypt again. Restart before decrypting if you have to.

Edit: password on your user account, if it wasn't clear.

I'm looking for a way to secure my "files" hard drive (not my primary OS hard drive). I want something that would allow me to decrypt it on boot, with a decryption password of some type. It would then need to also encrypt again when shutting down.

Could anyone recommend a program for this? It would also be preferred if the separate actions had their own executable or way to be run from command line so I could use it with another project of mine, but this isn't required.

Thanks to anyone that can point me in the right direction!

Hi All

I used the files and folders Encrypt attribute: "Properties>General>Encrypt contents to secure data"
to encrypt a folder and all its contents. The folder and all its contents are green of colour. Now this is on the D-drive. I formatted my windows C drive and now I cannot access any of the files inside the encrypted folder.

I try setting permissions but they are set for administrators and I'm an administrator. How do I decrypt them?

Thank you

Hello,
I have downloaded and used Kakasoft Shared folder protector to limit the access of some of my LAN-shared folders. The problem is that in my pc I had some "marica.exe" malware. Now, when I try to access my encrypted/protected folder I can only see this marica.exe and none of my files/folders. Hard disc appears to have 5GB of data on it, but I can't figure out how to restore them or fix this encrypted thing in order to make it work again... any ideas?? Note that i have not forgotten my password...

   Hi, I've been attacked by DirtyDecrypt virus but finally I "killed" it. Unfortunately alll my JPG and PDF files are ecrypted now!!!!!!
   Interesting fact: sometimes when I look inside a folder using Windows Explorer with "Medium Icons" some pictures show their content! This means that the image is still inside and can be seen!
   On the other hand when I try to open it using all the available possible programs all I get the virus picture telling me:
 
           File is encrypted
          This file can be decrypted using the DirtyDecrypt.exe
           Press CTRL+ALT+D to run DirtyDecrypt.exe
           OR
          Check the paths:
 
I tried decrypt_mblblock.exe but all I get is a message telling me that no encrypted file can be found.
What could/should I do next!
THANK YOU!!!!

How can I move a file from a bitlocker drive to a drive without encryption.
Bitlocker does not decrypt files when moving file from hard drive to another device. 
Computer (1) with bitlocker.  Computer (2) without bitlocker
When I move a file from Computer (1) to Computer (2) the file is not accessible on Computer (2).  I moved the file via an unencrypted USB.  The file is not being decrypted when it is moved to the USB.  
I can remove the decryption one file at a time by going to properties and advanced attributes by unchecking the "Encrpyt contents to secure data".  I have not found a way to have bitlocker to properly decrypt as the file or multiple files
are moved to another device.  
This is happened before and after a motherboard replacement that required a new encryption.

Hi Folks, here is the situation -

Running
Windows 2000 SR 1

I recently had to reinstall Windows 2000 to a new partition after some recent OS problems.

The problem now is that I formerly had a directory which I decided to encrypt using Win 2000's new encryption technology.

From what I understand is that the key used to encrypt the folder is based off my old SID. Now that I have reinstalled I am unable to view or delete any of the contents in that folder, even with Local Admin access and full ownership.

I've checked MS kbase and the only recourse would have been if I have used the backup tool to backup the key. Regardless to say I have no backups.

Now it would be nice if i could recover those encrypted files however I would be happy at this time if I could simply delete the whole folder.
I can view the filenames of the files but am unable to view/delete the files.

Any suggestions?

BTW the original WinNT directory has also been deleted.
 

A:Win2000 Server - Encrypted a folder, reinstalled, now cannot decrypt folder

did you ever find any resolution to this issue? I have a sorta/kinda similar situation where Active Directory became corrupt and SID's got cross-linked. Long story short I have the old SID and need to know how to apply it to a new user object in Active Directory. I've searched everywhere without luck on this one.

I know I have been hit by CryptoWall. I do however seem to see something that I have heard shouldn't be the case. I am hoping that this is a good sign. I have files that are duplicated but it seems that the original file is still there. ex.

AND

Problem remains the same both files are encrypted. Didn't know If this has been reflected in other forums and is something that is recoverable.
 
A response would be appreciated
 
Thanks for all you guys do.

A:Files encrypted but both regular and encrypted files remain.

A repository of all current knowledge regarding CryptoWall is provided by Grinler (aka Lawrence Abrams), in this tutorial: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQReading that Guide will help you understand what CryptoDefense does and provide information for how to deal with it and possibly decrypt/recover your files. At this time there is no fix tool for CryptoWall.There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense. Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion....from the above topic.CryptoWall victims,If you are thinking about paying the ransom, have decided to pay, or want to help test a few things for me, Please email me at [email protected] or PM me first.There may be other options for you, or can receive assistance with the infection.Nathan (DecrypterFixer), Security Colleague Post #273ThanksThe BC StaffNote: Although this infection has numerous similarities to CryptoLocker and CryptorBit, there is no evidence that they are related other than that they do the same thing.
