Assembly Ransomware

Assembly Ransomware may not be the a well-written ransomware but it can certainly cause a lot of damage if it manages to slither onto your PC. This new vicious program is based on the good old Hidden Tear Ransomware, which has been used by lots of cyber crooks to create off-springs like Sorry HT Ransomware and Cyberresearcher Ransomware, to mention a couple from the dozens of ransomware threats. This new ransomware may not target hundreds of file extensions and types, but it can still strike you hard. If you do not have a backup of your files stored safely on a portable device or in cloud storage, you can lose all of your encrypted files after this attack. Yet, we do not believe that it is a good idea to pay the ransom fee because it is quite unlikely that you will be able to restore your files. Cyber criminals rarely care about the victims once they get the money. In fact, it is more likely that they will infect your machine once again. If you want to stop this nightmare, we suggest that you remove Assembly Ransomware right now.

This ransomware seems to use the most frequent distribution method, which is spamming campaigns. By sending out thousands of spams with this malicious program as an attachment, there is a higher chance that lots of users may turn into victims within a short period of time. This mail can be very convincing and you may actually feel like you must open it. This is all pure psychology, to be frank. The sender of this email can be pretended to be someone authoritative like a police officer from the local police department, someone from a state department, a well-known hotel, or bank. Then, there is the subject field, which is just as convincing since it is mostly something that could related to anyone really, such as an unpaid parking fine or invoice, a wrongly made flight booking, and the like. The most important to remember about opening such spam mails and their attachment is that once you do so, there is no way back. You will not be able to delete Assembly Ransomware in time to save your precious files from being encrypted.

Another possibility for you to infect your computer with such a nightmarish program is to download software and cracks from suspicious torrent and other file-sharing websites. You should know that these sites are quite dangerous since they usually promote malicious software bundles and malware infections. Even if you do not click on any of the download buttons, you could easily drop such infections if you click on the wrong content. However, there is no way to stop the encryption even if you delete Assembly Ransomware in the end.

Our research indicates that this malware infection applies the usual AES-256 algorithm to encrypt your files. This ransomware does not target hundreds of extensions, but only 26. But this is just enough to lose your main image files, documents, and other third-party programs as well. Once a file is encrypted, it adds ".locked" extension to the original extension. You will find the ransom note .txt file ("READ_ME.txt") on your desktop. This note informs you that your files have been encrypted and you have to transfer 1,000 USD in Bitcoins to the provided address, which, by the way, still seems to be empty at the time of writing. This can mean that this ransomware infection is not yet widely spreading. You are also asked to send an email to "" with your computer name. We would never recommend that you pay any amount of money for cyber villains. But this is you choice to make. We advise you to act now and remove Assembly Ransomware from your PC.

If you are ready to act and would like to try to eliminate this dangerous ransomware infection manually, you can use our guide below as a reference. If you are lucky, this threat has already deleted itself. However, even if this might have happened, it can still leave some leftovers behind. To be frank, that best way to make sure that your computer is clean and it stays clean, too, is to download and install a proper anti-malware program like SpyHunter, or any other you can fully trust with the automatic protection of your computer. Remember that it is just as important that you regularly update all your programs and drivers to prevent cyber criminals from gaining access to your system via outdated software security bugs.
