As soon as you accept the license terms, the main decryptor user interface comes up:. Based on the default settings, the decryptor will automatically populate the available locations in order to decrypt the currently available drives the connected ones , including the network drives. Decryptors normally suggest several options considering the specific malware family. The current possible options are presented in the Options tab and can be activated or deactivated there.
You may locate a detailed list of the currently active Options below. Note that the main screen may turn you to a status view, letting you know of the active process and the decryption statistics of your data:. The decryptor will notify you as soon as the decryption procedure is completed.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your xcmb files:. Xcmb ransomware encryption mechanism feature is next: it encrypts every file byte-by-byte, then saves a file copy, deleting and not overriding!
Hence, the information of the file location on the physical disk is lost, but the original file is not deleted from the physical disk. The cell, or the sector where this file was stored, can still contain this file, but it is not listed by the file system and can be overwritten by data that has been loaded to this disk after the deletion. Hence, it is possible to recover your files using special software.
Anyway, after realizing it was an online algorithm, it is impossible to retrieve my encrypted files. I also had my backup drive plugged in at the time of the virus, and this was also infected, or so I thought. Every folder within my backup drive had been infected and was encrypted.
When I started going through the folders, I noticed the readme. I opened some of the folders and found that all files that were not in a subfolder within that folder had been encrypted. However, I found a flaw and glimmer of hope when I went into the subfolders in other folders and found that these files had not been encrypted.
Every folder within my c and d drives, including subfolders, had been encrypted, but this was not the case with the backup drive. As I said, I believe this to be only a small loophole on a backup drive. So my advice is if you use a backup drive, create subfolders. I was lucky, I guess. But I was also unlucky that the virus hit as I was transferring some files from my backup. PhotoRec is an open-source program, which is originally created for files recovery from damaged disks, or for files recovery in case if they are deleted.

The best desicion is to export them on USB drive or any other type of removable disk.
Then, you need to specify the file formats. This option is located at the bottom, too. As it was mentioned, PhotoRec can recover the files of about different formats. You will see the screen where the results of the scan and recovery are shown. How can I decrypt them urgently? If your data remained in the. If not, then you can try to restore them through the system function — Restore Point.
All other methods will require patience. Does this mean that the program will delete my encrypted files? Of course not. Your encrypted files do not pose a threat to the computer.
What happened has already happened. You need GridinSoft Anti-Malware to remove active system infections.

Tolong, beri tahu saya di komentar jika itu berhasil untuk Anda. Ekstensi terbaru dirilis sekitar akhir Agustus setelah para penjahat melakukan perubahan. Ini termasuk Wiot , Efdc , Lqqw , dll. Mulailah mengunduh alat dekripsi. Pastikan untuk meluncurkan utilitas dekripsi sebagai administrator. Anda harus menyetujui persyaratan lisensi yang akan muncul. Segera setelah Anda menerima persyaratan lisensi, antarmuka pengguna decryptor utama akan muncul:.
Berdasarkan pengaturan default, decryptor akan secara otomatis mengisi lokasi yang tersedia untuk mendekripsi drive yang tersedia saat ini yang terhubung , termasuk drive jaringan. Decryptors biasanya menyarankan beberapa opsi dengan mempertimbangkan keluarga malware tertentu. Opsi yang memungkinkan saat ini disajikan di tab Opsi dan dapat diaktifkan atau dinonaktifkan di sana.

Fitur mekanisme enkripsi ransomware Djvu adalah yang berikutnya: mengenkripsi setiap file byte-by-byte, kemudian menyimpan salinan file, menghapus dan tidak menimpa! File asli. Oleh karena itu, informasi lokasi file pada disk fisik hilang, tetapi file asli tidak dihapus dari disk fisik.
Sel, atau sektor tempat file ini disimpan, masih dapat berisi file ini, tetapi tidak terdaftar oleh sistem file dan dapat ditimpa oleh data yang telah dimuat ke disk ini setelah penghapusan. Karenanya, dimungkinkan untuk memulihkan file Anda menggunakan perangkat lunak khusus. PhotoRec adalah program sumber terbuka, yang pada awalnya dibuat untuk pemulihan file dari disk yang rusak, atau untuk pemulihan file jika dihapus. Namun, seiring berjalannya waktu, program ini memiliki kemampuan untuk memulihkan file dari ekstensi yang berbeda.
Karenanya, ini dapat digunakan untuk pemulihan data setelah serangan ransomware. Pertama, Anda perlu mengunduh aplikasi ini download link. PhotoRec didistribusikan dalam satu paket dengan utilitas lain dari pengembang yang sama — TestDisk. Arsip yang diunduh akan memiliki nama TestDisk, tetapi jangan khawatir. File PhotoRec ada di dalam. Setelah peluncuran, Anda akan melihat layar yang menampilkan daftar lengkap ruang disk Anda.
Namun, informasi ini sepertinya tidak berguna, karena menu yang dibutuhkan ditempatkan sedikit lebih tinggi. Klik bilah ini, lalu pilih disk yang diserang oleh ransomware.
Setelah memilih disk, Anda harus memilih folder tujuan untuk file yang dipulihkan. Menu ini terletak di bagian bawah jendela PhotoRec. Keputusan terbaik adalah mengekspornya ke drive USB atau jenis disk yang dapat dilepas lainnya.
Kemudian, Anda perlu menentukan format file. Opsi ini juga terletak di bagian bawah. Seperti yang telah disebutkan, PhotoRec dapat memulihkan file dari sekitar format berbeda. Anda akan melihat layar di mana hasil pemindaian dan pemulihan ditampilkan. Bagaimana saya bisa segera mendekripsi mereka? Jika data Anda tetap berada di file. Jika tidak, maka Anda dapat mencoba memulihkannya melalui fungsi sistem — Restore Point.
Semua metode lain membutuhkan kesabaran. Apakah ini berarti program akan menghapus file terenkripsi saya? Tentu saja tidak. File terenkripsi Anda tidak menimbulkan ancaman bagi komputer.
Apa yang terjadi sudah terjadi. Anda memerlukan GridinSoft Anti-Malware untuk menghapus infeksi sistem yang aktif. Virus yang mengenkripsi file Anda kemungkinan besar masih aktif dan secara berkala menjalankan tes untuk kemampuan mengenkripsi lebih banyak file.

Dalam situasi ini, Anda perlu menyiapkan stik memori dengan Trojan Killer yang sudah diinstal sebelumnya. Apa yang harus saya lakukan? Anda terinfeksi dengan versi baru ransomware Djvu, dan kunci dekripsi belum dirilis.
