Cara Membuka, Decrypt, & Menghapus AACT (AACT) atau STOP DJVU ransomware virus

What kind of malware is AACT?

AACT adalah ransomware yang memblokir akses ke file dengan mengenkripsinya. Juga, itu membuat catatan teror (file “_readme.txt“) dan menambahkan ekstensi “.AACT” ke nama file. Misalnya, mengubah nama “1.jpg” menjadi “1.jpg.AACT”, “FILE PENTING.xlsx” menjadi “FILEPENTING.xlsx.AACT”. AACT masuk ke kategori keluarga ransomware bernama STOP DJVU.

Anda dapat menemukan sample file seperti .AACT yang berhasil dipecahkan Fixransomware.com dari LINK BERIKUT:

Analisis Catatan / Pesan Teror dari Hacker

Sebagaimana dinyatakan dalam catatan teror, Hacker meminta tebusan dalam waktu 72 jam atau data akan dihapus, hal ini untuk membuat para korban panik dan mengikuti apa yang mereka tuntut sehingga hacker dapat memeras korban dengan mudah. Berdasarkan laporan korban ransomware harian di fixransomware.com, telah ditemukan ratusan laporan bahwa hacker tidak memberikan software dan kode decryption setelah korban berulang kali membayar tebusan tambahan. Screenshot dari chat dapat ditemukan disini:

Dalam semua laporan kasus, korban ransomware tidak dapat memulihkan file secara gratis kecuali mereka memiliki salinan file mereka atau software dekripsi pihak ketiga tersedia di Internet. Umumnya, software dekripsi tidak dapat bekerja karena ransomware generasi baru mengenkripsi data korban secara online dan membuat sebuah kunci khusus untuk satu korban itu saja. Selain itu, menggunakan software pihak ketiga juga dapat merusak susunan file anda. Untuk alasan ini, disarankan untuk memiliki cadangan data dan menyimpannya di server Cloud seperti Google drive dan Icloud atau NAS Server.

Sebagaimana laporan di grup ransomware terbesar pada link berikut. Membayar tebusan tidak menjamin bahwa pelaku ancaman akan memberikan kunci atau software dekripsi karena beberapa hacker hanya menyebarkan virus dan mendapatkan bayaran. Para hacker umumnya membeli virus ransomware dari kelompok kriminal acak di dark web. Kelompok kriminal ini tidak memperdulikan reputasi mereka bahkan setelah menipu banyak korban di banyak negara karena mereka dapat berganti identitas dan membuat varian virus baru lagi. Dalam berita baru-baru ini, peretas tidak mendekripsi file korban sampai sepenuhnya mengambil semua uang korban. Jadi mereka menuntut lebih banyak uang tebusan tetapi file Anda tidak akan pulih sepenuhnya. Plus privasi perusahaan Anda akan terbuka atau perangkat Anda yang lain akan terinfeksi begitu mereka mendapatkan akses ke PC Anda. Umumnya semua serangan ransomware dibekali dengan spyware. Spyware ini dapat mengambil password dan data penting anda dalam hitungan detik dari browser dan cache. Data ini kemudian dijual ke darkweb. Sehingga jika anda terinfeksi, diwajibkan bagi anda untuk mematikan koneksi internet dan menghubungi tim fixransomware.com secepatnya untuk tindak lanjut darurat pada link berikut:

Bagaimana Ransomware Masuk Ke Jaringan PC Anda?

Penjahat dunia maya mendistribusikan ransomware melalui email, sumber yang tidak dapat dipercaya untuk mengunduh file/program, pembaruan perangkat lunak palsu, Trojan, dan masih banyak lagi celah seperti Firewall dan RDP yang dapat dimanfaatkan. Ransomware dikirimkan melalui email dengan mengirimkan lampiran atau tautan. Umumnya serangan ransomware akan berjalan berulang kali. Beberapa kelompok hacker membocorkan skema celah jaringan anda ke kelompok lainnya untuk menyerang di kemudian hari. Maka dari itu, hubungi tim Teknisi Fixransomware.com untuk menghindarkan anda dari serangan berikutnya:

Malicious files downloaded from unofficial websites, third-party downloaders, Peer-to-Peer networks, and other unreliable sources infect devices when users execute them too. Fake software updaters are designed to exploit bugs, flaws of outdated software or inject malware instead of fixes/updates.

Software cracking tools activate legitimate software. Using pirated software (or cracking tools to activate software) is against the law. Another reason not to use such tools (and the installers mentioned above) is that they often contain malware (for example, ransomware).

100% Solution to Restore Your Data Lossless:

One best solution is to decrypt the ransomware with online ID is by manually using various techniques, such as Asymmetric decryption [aka. Public-Key Cryptography] (RSA, El Gamal etc.), Key Exchange Algorithms (Diffie-Hellman), and Cryptanalysis.

DIGIPEDIA is a tech company consisted hundreds of cybersecurity technicians are ready to do the decryption. We are the number 1 Asymmetric decryption company in Asia with success rate 100%. We have succeeded in helping many MNC and national companies, from Palestine to Spain to restore 100% of their datacenters.

Alternative Solutions – How to Restore your Data using Universal Decryptor or Repair Tool:

There are currently two versions of Djvu ransomware: old and new. The old versions were designed to encrypt data by using a hard-coded “offline key” whenever the infected machine had no internet connection or the server was timing out/not responding.

There are currently two versions of Djvu ransomware infections: old and new. The old versions were designed to encrypt data by using a hard-coded “offline key” whenever the infected machine had no internet connection or the server was timing out/not responding.

Therefore, some victims were able to decrypt data using a tool developed by cyber security researcher, Michael Gillespie, however, since the encryption mechanism has been slightly changed (hence the new version, released in August, 2019), the decrypter no longer works and it is not supported anymore.

If your data has been encrypted by an older version, you might be able to restore it with the another tool developed by Emsisoft and Michael Gillespie. It supports a total of 148 Djvu’s variants and you can find more information, as well as download link and decryption instructions in Emsisoft’s official page.

Additionally, Emsisoft is now providing a service that allows to decrypt data (again, only if it was encrypted by Djvu variants released before August, 2019) for those victims who have a pair of the same file before and after the encryption. All victims have to do is upload a pair of original and encrypted file to Emsisoft’s Djvu decryption page and download the aforementioned decryption tool (the download link will be provided after uploading files).

Note that the file processing may take some time so be patient. It is also worth mentioning that the system must have an Internet connection during the entire decryption process, otherwise it will fail.

Now it is worth noting that Djvu ransomware does not encrypt the entire file. Instead, it encrypts only a portion (start) of the file, thereby making it unusable. Luckily, in some cases it is possible to restore other part of the file, which is not encrypted. This is useful when it comes to audio/video files, because even though the start won’t be restored, you’ll still be able to use most of it.

This is useful when it comes to audio/video files, because even though the start won’t be restored, you’ll still be able to use most of it.

To restore audio/video data we advise you to use Media_Repair tool developed by DiskTuna. This tool is extremely simple and completely free. You can find the user manual as well as download the tool directly from DiskTuna’s website.

G DATA company has also released a “vaccine” capable of preventing Djvu ransomware from encrypting data. This does not mean that the malware won’t be able to enter the system or to perform other actions (e.g., change system settings). However, the encryption will be prevented nevertheless. You can download the vaccination tool from this GitHub page.

Quick menu:

Reporting ransomware to authorities:

If you are a victim of a ransomware attack we recommend reporting this incident to authorities. By providing information to law enforcement agencies you will help track cybercrime and potentially assist in the prosecution of the attackers. Here’s a list of authorities where you should report a ransomware attack. For the complete list of local cybersecurity centers and information on why you should report ransomware attacks, read this article.

List of local authorities where ransomware attacks should be reported (choose one depending on your residence address):

Isolating the infected device:

Some ransomware-type infections are designed to encrypt files within external storage devices, infect them, and even spread throughout the entire local network. For this reason, it is very important to isolate the infected device (computer) as soon as possible.

Step 1: Disconnect from the internet.

The easiest way to disconnect a computer from the internet is to unplug the Ethernet cable from the motherboard, however, some devices are connected via a wireless network and for some users (especially those who are not particularly tech-savvy), disconnecting cables may seem troublesome. Therefore, you can also disconnect the system manually via Control Panel:

Navigate to the “Control Panel“, click the search bar in the upper-right corner of the screen, enter “Network and Sharing Center” and select search result:Disconnecting computer from the Internet (step 1)

Click the “Change adapter settings” option in the upper-left corner of the window:Disconnecting computer from the Internet (step 2)

Right-click on each connection point and select “Disable“. Once disabled, the system will no longer be connected to the internet. To re-enable the connection points, simply right-click again and select “Enable“.Disconnecting computer from the Internet (step 3)

Step 2: Unplug all storage devices.

As mentioned above, ransomware might encrypt data and infiltrate all storage devices that are connected to the computer. For this reason, all external storage devices (flash drives, portable hard drives, etc.) should be disconnected immediately, however, we strongly advise you to eject each device before disconnecting to prevent data corruption:

Navigate to “My Computer“, right-click on each connected device, and select “Eject“:Ejecting external storage devices

Step 3: Log-out of cloud storage accounts.

Some ransomware-type might be able to hijack software that handles data stored within “the Cloud“. Therefore, the data could be corrupted/encrypted. For this reason, you should log-out of all cloud storage accounts within browsers and other related software. You should also consider temporarily uninstalling the cloud-management software until the infection is completely removed.

Identify the ransomware infection:

To properly handle an infection, one must first identify it. Some ransomware infections use ransom-demand messages as an introduction (see the WALDO ransomware text file below).

Identify ransomware-type infection (step 1)

This, however, is rare. In most cases, ransomware infections deliver more direct messages simply stating that data is encrypted and that victims must pay some sort of ransom. Note that ransomware-type infections typically generate messages with different file names (for example, “_readme.txt“, “READ-ME.txt“, “DECRYPTION_INSTRUCTIONS.txt“, “DECRYPT_FILES.html“, etc.). Therefore, using the name of a ransom message may seem like a good way to identify the infection. The problem is that most of these names are generic and some infections use the same names, even though the delivered messages are different and the infections themselves are unrelated. Therefore, using the message filename alone can be ineffective and even lead to permanent data loss (for example, by attempting to decrypt data using tools designed for different ransomware infections, users are likely to end up permanently damaging files and decryption will no longer be possible even with the correct tool).

Another way to identify a ransomware infection is to check the file extension, which is appended to each encrypted file. Ransomware infections are often named by the extensions they append (see files encrypted by Qewe ransomware below).

Identify ransomware-type infection (step 2)

This method is only effective, however, when the appended extension is unique – many ransomware infections append a generic extension (for example, “.encrypted“, “.enc“, “.crypted“, “.locked“, etc.). In these cases, identifying ransomware by its appended extension becomes impossible.

One of the easiest and quickest ways to identify a ransomware infection is to use the ID Ransomware website. This service supports most existing ransomware infections. Victims simply upload a ransom message and/or one encrypted file (we advise you to upload both if possible).

Identify ransomware-type infection (step 3)

The ransomware will be identified within seconds and you will be provided with various details, such as the name of the malware family to which the infection belongs, whether it is decryptable, and so on.

Example 1 (Qewe [Stop/Djvu] ransomware):

Identify ransomware-type infection (step 4)

Example 2 (.iso [Phobos] ransomware):

Identify ransomware-type infection (step 5)

If your data happens to be encrypted by ransomware that is not supported by ID Ransomware, you can always try searching the internet by using certain keywords (for example, a ransom message title, file extension, provided contact emails, crypto wallet addresses, etc.).

Disabling the Virus in Windows Startup, Scheduler, Hosts, and Task manager:

Search for ransomware decryption tools:

Encryption algorithms used by most ransomware-type infections are extremely sophisticated and, if the encryption is performed properly, only the developer is capable of restoring data. This is because decryption requires a specific key, which is generated during the encryption. Restoring data without the key is impossible. In most cases, cybercriminals store keys on a remote server, rather than using the infected machine as a host. Dharma (CrySis), Phobos, and other families of high-end ransomware infections are virtually flawless, and thus restoring data encrypted without the developers’ involvement is simply impossible. Despite this, there are dozens of ransomware-type infections that are poorly developed and contain a number of flaws (for example, the use of identical encryption/decryption keys for each victim, keys stored locally, etc.). Therefore, always check for available decryption tools for any ransomware that infiltrates your computer.

Finding the correct decryption tool on the internet can be very frustrating. For this reason, we recommend that you use the No More Ransom Project and this is where identifying the ransomware infection is useful. The No More Ransom Project website contains a “Decryption Tools” section with a search bar. Enter the name of the identified ransomware, and all available decryptors (if there are any) will be listed.

Create data backups:

Proper file management and creating backups is essential for data security. Therefore, always be very careful and think ahead.

Partition management: We recommend that you store your data in multiple partitions and avoid storing important files within the partition that contains the entire operating system. If you fall into a situation whereby you cannot boot the system and are forced to format the disk on which the operating system is installed (in most cases, this is where malware infections hide), you will lose all data stored within that drive. This is the advantage of having multiple partitions: if you have the entire storage device assigned to a single partition, you will be forced to delete everything, however, creating multiple partitions and allocating the data properly allows you to prevent such problems. You can easily format a single partition without affecting the others – therefore, one will be cleaned and the others will remain untouched, and your data will be saved. Managing partitions is quite simple and you can find all the necessary information on Microsoft’s documentation web page.

Data backups: One of the most reliable backup methods is to use an external storage device and keep it unplugged. Copy your data to an external hard drive, flash (thumb) drive, SSD, HDD, or any other storage device, unplug it and store it in a dry place away from the sun and extreme temperatures. This method is, however, quite inefficient, since data backups and updates need to be made regularly. You can also use a cloud service or remote server. Here, an internet connection is required and there is always the chance of a security breach, although it’s a really rare occasion.

We recommend using Microsoft OneDrive for backing up your files. OneDrive lets you store your personal files and data in the cloud, sync files across computers and mobile devices, allowing you to access and edit your files from all of your Windows devices. OneDrive lets you save, share and preview files, access download history, move, delete, and rename files, as well as create new folders, and much more.

You can back up your most important folders and files on your PC (your Desktop, Documents, and Pictures folders). Some of OneDrive’s more notable features include file versioning, which keeps older versions of files for up to 30 days. OneDrive features a recycling bin in which all of your deleted files are stored for a limited time. Deleted files are not counted as part of the user’s allocation.

The service is built using HTML5 technologies and allows you to upload files up to 300 MB via drag and drop into the web browser or up to 10 GB via the OneDrive desktop application. With OneDrive, you can download entire folders as a single ZIP file with up to 10,000 files, although it can’t exceed 15 GB per single download.

OneDrive comes with 5 GB of free storage out of the box, with an additional 100 GB, 1 TB, and 6 TB storage options available for a subscription-based fee. You can get one of these storage plans by either purchasing additional storage separately or with Office 365 subscription.

Creating a data backup:

The backup process is the same for all file types and folders. Here’s how you can back up your files using Microsoft OneDrive

Step 1: Choose the files/folders you want to backup.

Click the OneDrive icon in the taskbar

Click the OneDrive cloud icon to open the OneDrive menu. While in this menu, you can customize your file backup settings.

Select Help & Settings and click Settings

Click Help & Settings and then select Settings from the drop-down menu.

Select the Backup tab and click Manage backup

Go to the Backup tab and click Manage backup.

Select folders to backup and click Start backup

In this menu, you can choose to backup the Desktop and all of the files on it, and Documents and Pictures folders, again, with all of the files in them. Click Start backup.

Now, when you add a file or folder in the Desktop and Documents and Pictures folders, they will be automatically backed up on OneDrive.

To add folders and files, not in the locations shown above, you have to add them manually.

Select a file manually and copy it

Open File Explorer and navigate to the location of the folder/file you want to backup. Select the item, right-click it, and click Copy.

Paste the copied file in the OneDrive folder to create a backup

Then, navigate to OneDrive, right-click anywhere in the window and click Paste. Alternatively, you can just drag and drop a file into OneDrive. OneDrive will automatically create a backup of the folder/file.

File statuses in OneDrive folder

All of the files added to the OneDrive folder are backed up in the cloud automatically. The green circle with the checkmark in it indicates that the file is available both locally and on OneDrive and that the file version is the same on both. The blue cloud icon indicates that the file has not been synced and is available only on OneDrive. The sync icon indicates that the file is currently syncing.

Click Help & Settings and click View Online

To access files only located on OneDrive online, go to the Help & Settings drop-down menu and select View online.

Click the Settings cog and click Options

Step 2: Restore corrupted files.

OneDrive makes sure that the files stay in sync, so the version of the file on the computer is the same version on the cloud. However, if ransomware has encrypted your files, you can take advantage of OneDrive’s Version history feature that will allow you to restore the file versions prior to encryption.

Microsoft 365 has a ransomware detection feature that notifies you when your OneDrive files have been attacked and guide you through the process of restoring your files. It must be noted, however, that if you don’t have a paid Microsoft 365 subscription, you only get one detection and file recovery for free.

If your OneDrive files get deleted, corrupted, or infected by malware, you can restore your entire OneDrive to a previous state. Here’s how you can restore your entire OneDrive:

restore-your-onedrive

1. If you’re signed in with a personal account, click the Settings cog at the top of the page. Then, click Options and select Restore your OneDrive.

If you’re signed in with a work or school account,  click the Settings cog at the top of the page. Then, click Restore your OneDrive.

2. On the Restore your OneDrive page, select a date from the drop-down list. Note that if you’re restoring your files after automatic ransomware detection, a restore date will be selected for you.

3. After configuring all of the file restoration options, click Restore to undo all the activities you selected.

The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups.
