Masodas ransomware virus

Ransomware is a type of malware from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem – and difficult to trace digital currencies such as Ukash or Bitcoin and other cryptocurrency are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

From Wiki

Ransomware is one of the worst virus type because of two factors easy to find, hard to remove the consequences.

Masodas ransomware is the brightest instance of encrypting malware: it’s not difficult to pick up and too hard to remove, but we can help you with it. Masodas is the part of DJVU_STOP family. In today's item, we want to tell you what is ransomware and the manners of its penetration into your workstation. We will make it clear to you what measures you must take to evade encrypting virus' infestation, and how you can get your information back. Remember that many these viruses will not ever get decrypted, so if you have one – your data might be already gone forever. In rare cases, hackers make an error and antivirus experts can find the way to neutralize the virus or to restore the information.



The point is that all viruses take advantage of the unbeatable encoding algorithms, known as the RSA and the AES. They are very sophisticated and can’t be decrypted. Of course, you might decrypt them, having a hundred years of regular PC’s working time or a few years of work on the most efficient machine in the world. We're sure that neither of the given options suits a user. We will teach you that ransomware can plainly be avoided, but if one of them is already on your computer – you are in trouble.

 RSA (Rivest–Shamir–Adleman) is one of the first public-key cryptosystems and is widely used for secure data transmission. In such a cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private). In RSA, this asymmetry is based on the practical difficulty of the factorization of the product of two large prime numbers, the "factoring problem".

The encrypting malware, AKA ransomware, are the viruses that infest customers' computers and waste their info to earn money for its restoration. The penetration is usually performed with the help of email spam or zero-day Trojans. E-mail spam is very easy to identify – it will be sent without any notice, and there will be some files in it. When it comes to zero-day vulnerabilities, it’s a bit harder – you'll never know what it will be before the computer gets infected so that the most effective method is to properly update the system and other tools which you use.

Regular encrypting programs are not too intricate in their code, yet even the clumsiest virus is extremely perilous, and we’ll explain to you why. They all apply the super-complex mechanisms of encryption. Ransomware doesn't physically steal the data. It only wants to get into the OS, spoil your files and remove the original data, placing the encrypted versions instead of them. You can't use those files after that. You can’t use the files and cannot return them to their previous condition. We know few techniques to restore the files, and we've defined them all in this piece.

If the job is finished, scammers give you a ransom note, and when it appeared – you know that the information is spoiled. There's only one measure you can take now - to delete ransomware from the PC and concentrate on the data restoration. We've said “attempt” because the odds to succeed not having a decryptor are ghostly.

Masodas removal guide

You need to delete virus until you start working on data decryption because if it stays on your system – it can begin encrypting each file, which comes into the PC. You should realize that any flash drive you are sticking into the corrupted computer will get ciphered also. We are certain that it's not good for you, so simply delete ransomware through sticking to our useful advice. Keep in mind that the uninstallation will not reverse caused damage, and after doing this, you won’t be able to pay money to hackers. We suggest doing that since every ransom earned makes web-criminals more to feel their feet in what they do and gives them more money to invent intricate viruses. It's worth mentioning that when you’re forced to deal with fraudsters, they won't give you a proof that the data will be restored when they take the money. They have already decrypted your data, and we don't think that you want to give them the ransom after that.

Masodas decryption instruction

When you remove Masodas from your computer, and you're sure about it, you need to think about the recovery ways. Firstly, we should say that the sole 100% effective technique is to use the security copies. If you have the backups of the data and Masodas is entirely removed – simply remove the spoiled information and upload the backups. In case there were no backup copies – the chances to restore your files are slim to none. The only way to succeed is the Shadow Volume Copies. We're talking about the common tool of Windows, and it saves all the changed or removed data. They can be reached with the help of specific restoration tools.

Of course, the modern viruses can delete these files, but if you're working from a profile with no master rights, the ransomware simply had no way do that without the allowance. You may remember that sometime prior to the showing of a scammer's note there was another menu, asking to apply changes to the computer. If you've declined those alterations – your copies are still there waiting for you, so you can use them and recover the files through custom tools as ShadowExplorer or Recuva. You can simply find them both on the Internet. You may get them from the sites of their developers, with detailed instructions.
