File extension changed

January 30th, 2015, 14:17

Hello ,

All excel/word/zip/pdf are changed as following
Doc1.DOCX.tvmpzfh
Eng..PDF.tvmpzfh
Expenses.XLSX.tvmpzfh

i tried changing extension but no use .File size seems ok like 1.2 MB .

Is this cryptowall virus? i tried uploading file to https://www.decryptcryptolocker.com/ but saying no encrypted file.
In pc3000 raw recovery dont show these files.

Any one faced similar issue or any solution

Thanks in advance

Had a client with similar issue, theirs was something like .mtvoish

Client was a dealer who eradicated the malware without noting what it was exactly. They said it was "crypto something or other" ... Helpful!

Observed 2-3 more cases with same issue.
Virus get removed but Asking 500 or 1000usd to decrypt and asking deposit amount in given bank details which account is unknown .

I'm assuming that you are victim of ransomware called CTB-Locker. For now is no other way than brute force or pay the ransom.

I think this is only matter of time when other new modification will appear. And I think this will be when CTB-Locker will be busted.
