Assm ransomware – a dangerous malware that can result in personal data loss

The Assm virus is a malicious computer program known for its ability to encrypt all personal files, including photos, videos, databases, documents, and more, making them inaccessible. The RSA encryption algorithm used by the virus makes the files unusable until they are decrypted with a key that is held on the cybercriminals' servers.
When this happens, the personal files are appended with the .assm extension, and their regular file icons disappear. Users are unable to open the files and receive a Windows error message stating that the file cannot be recognized. The cybercriminals behind the attack then quickly take advantage of the situation and demand payment of $490/$980 in bitcoin to retrieve access to the encrypted data. They provide support@freshmail.top and datarestorehelp@airmail.cc email addresses for communication.
Assm is part of the highly prevalent Djvu malware family, which has had over 600 variants since its release, including Mztu, Mzop, Poqw, and many others. In this case, we will discuss how to deal with the dangerous Assm infection and provide steps for attempting to restore the encrypted files without paying the cybercriminals.

| File Recovery | There is no guaranteed way to recover locked files without backups. Other options include paying cybercriminals (not recommended, might also lose the paid money), using Emisoft's decryptor (works for a limited number of victims), or using third-party recovery software |
| Malware removal | After disconnecting the computer from the network and the internet, do a complete system scan using the SpyHunterCombo Cleaner security program |
| System fix | As soon as it is installed, malware has the potential to severely harm some system files, causing instability problems, including crashes and errors. Any such damage can be automatically repaired by using FortectIntego PC repair |
How cybercriminals attempt to convince people to pay the ransom
When ransomware infects a device, it displays a ransom note on the user's screen. This message provides instructions for how to pay an extortion sum in exchange for the decryption of their data, which was encoded by the malicious software.
The Assm virus Ransomware note requires payment in exchange for a decryption key needed to regain access to the encrypted files. Most commonly, this is demanded as cryptocurrency like Bitcoin, with instructions on how to make the payment included inside of it. Here's what the message says:
ATTENTION!
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.
The only method of recovering files is to purchase decrypt tool and unique key for you.
This software will decrypt all your encrypted files.
What guarantees you have?
You can send one of your encrypted file from your PC and we decrypt it for free.
But we can decrypt only 1 file for free. File must not contain valuable information.

Cybercriminals attempt to convince victims that paying the ransom is the best choice they can pick. The attackers always offer victims a 50% discount if they pay within the three-day period, and even provide free decryption services to test out their service. It's all an attempt to manipulate people into believing that cooperating with them quickly is in their best interest.

There are several reasons why it is not recommended to pay the ransom after being infected with ransomware:
- No guarantee of file recovery: There is no guarantee that the cybercriminals will provide the decryption key after the ransom is paid, and many victims have reported that they did not receive the promised decryption key even after paying the ransom.
- Supports criminal activity: Paying the ransom funds the activities of cybercriminals and can contribute to the continued development and spread of ransomware and other forms of cybercrime.
- Encourages further attacks: Paying the ransom can encourage cybercriminals to target more victims and carry out similar attacks in the future.
- Alternative solutions: In some cases, there may be alternative solutions to recover encrypted files, such as using backups or attempting to use decryption tools provided by security experts.
The best thing to do is ignore attackers' demands and instead, rely on alternative methods for data recovery we provide below. But first, you need to make sure that you remove Assm ransomware from your system thoroughly.
Remove the virus
Ransomware is usually programmed to self-destruct after finishing the encryption process, as its main goal is to prevent access to users' files on their computers. There could be a myriad of important data, including invaluable pictures, school work or job projects, and more.
In some cases, however, malware can continue to run in the background to encrypt all the incoming data as well so that users would suffer even more damage. Assm ransomware is unlikely to behave like this, although it was previously found that it can deliver malicious modules designed to steal personal data via the browser or other means. Besides, Djvu versions were seen being distributed along with Trojans as Vidar, so removing all the malicious components is imperative.
You can delete all ransomware and other infections with an up-to-date version of SpyHunterCombo Cleaner or MalwarebytesMalwarebytes security software – it can perform a full scan and get rid of everything malicious at once. Before doing so, please disconnect your computer from the internet and network, if applicable.
If malware is interfering with this step, you should access Safe Mode, as malware's operation is temporarily suspended there. You can find relevant details on how to reach that mode below.
Data recovery steps and further remediation
Contrary to popular belief, anti-malware software is not capable of restoring personal files. On the contrary, its main objective is to protect you from digital threats and detect any malicious programs – it cannot decypher data previously encrypted by ransomware as this requires a different approach altogether. Despite that, one thing remains clear: having your device secured with security software is essential for protecting yourself online.
Once ransomware is installed, files become encrypted, and a unique ID, together with a unique encryption key, is created. The attackers then receive this information which can be correlated with the decryptor to access users' data. However, they won't provide you with it without any monetary compensation, as that's how these criminals turn a profit.
Instead of paying, we recommend you try the alternative solutions we list below. Before proceeding, you should make a copy of the encrypted data first, as it may get corrupted when trying to restore it.
Once you have dealt with your files, please run a scan with FortectIntego PC repair software, which can fix any damaged system files for you, preventing post-infection issues such as crashes or errors.
Don't forget to recreate the “hosts” file, as the Assm virus might prevent you from visiting certain websites otherwise. Finally, learn how to create useful backups for the future – the best defense against ransomware is to have backups ready in case the infections occur. Always have reputable anti-malware running in the background, and never ignore warnings coming from it.
