Remove Masodas ransomware (Virus Removal Guide) - Recovery Instructions Included

removal by Olivia Morelli - - | Type: Ransomware

Masodas ransomware is type of malware that provides ransom payment instructions after the file encryption

Masodas ransomware virus

Masodas ransomware is a file locking virus that enters the machine after victims open a malicious spam email attachment, download pirated software, fail to update the operating system on time, use weak RDP protection,[1] etc. Soon after the infiltration, the malware makes use of AES or another powerful encryption algorithm to lock pictures, videos, databases, documents, and other files.

Additionally, Masodas ransomware changes the way Windows operates by altering the Windows registry, and other alternations to perform the encryption process without interruption. After that, all the personal data is marked with .masodas extension and is no longer accessible to users.

Masodas virus also places a ransom note _readme.txt in order to provide users with information – they are asked to contact hackers via the gorentos@bitmessage.ch or gorentos2@firemail.cc and then pay $980 or $490 ransom in Bitcoin to retrieve the data. Masodas ransomware belongs to STOP/Djvu family, so experts recommend avoiding cybercriminals and instead of trying alternative data recovery solutions, including using the STOPDecrypter tool.

Distribution Spam emails, exploits, weak RDP connections, fake updates, web injects, etc.
File extension  .masodas

Contact gorentos@bitmessage.ch or gorentos2@firemail.cc 
File decryption STOPDecrypter [download link] and third-party recovery software might help; otherwise, files can only be recovered via backups
Termination You should remove the malware by using security software like Reimage or SpyHunter 5Combo Cleaner

Masodas ransomware targets the most common files that can be found on a regular computer system, such as .jpg, .mpg, .html, .xls, .mp3, .zip, .db, .doc, etc. after the encryption, the files are converted into the following: [file_name].[file_extension].masodas. Thus, a picture.jpg is turned into picture.jpg.masodas, and files modified in such a way can no longer be opened and no data can be extracted.

It is worth noting that the data encrypted by Masodas virus is not corrupted – it is merely locked by a unique key that resides on a remote server only accessible for hackers. That what makes ransomware viruses so dangerous, as much of valuable data might be lost simply because the victim is unable to pay the required ransom. Nevertheless, Masodas ransomware removal should be the top priority, and paying the ransom is not recommended in the first place.

To convince users to pay the demanded ransom in Bitcoin, hackers even offer a 50% discount in the ransom message that reads:

Even if you can afford the ransom or the discount is attractive to you, keep in mind that Masodas ransomware authors might never send you the required decryption tool, so you will end up losing your money along with the personal data. Thus, instead, remove Masodas ransomware using security software like Reimage or SpyHunter 5Combo Cleaner and then proceed with alternative file recovery solutions.

Masodas virus
Masodas virus - ransomware that can come delivered through malicious executables, p2p sites, fake updates, etc.

For that, you can either employ a specific tool – STOPDecrypter, which might work if the encryption process was performed when your computer was offline or the malware was unable to contact the C&C server.[2] Alternatively, you might try to employ third-party recovery solutions, although the chances of them working are relatively slim. If that does not work, the only choice is to make a copy of the .masodas files and wait till a working tool is released.

Ransomware hiding places throughout the Web sphere

Internet security experts from NoVirus.uk[3] state that the most popular ransomware distribution source is email spam. Criminals attach the malicious payload in the form of an executable, word document, or zip file. Also, the malware might come inserted into a particular hyperlink inside in the message body.

Ransomware viruses and other malware can come injected into bogus hyperlinks and adverts on unprotected networks such as peer-to-peer ones, online-gaming, streaming, gambling, and similar ones. Also, malicious apps might be disguised as fake software updates or handy products.

There are some ways to avoid secret ransomware infiltrations, and you should follow these tips if your goal is to ensure full computer and data security. First thing you should know is that anti-malware protection is ALWAYS necessary. When you take care of your antivirus tool, you should proceed with manual safety measures.

Furthermore, manage all of your emails received. Verify the sender and check the entire text for possible grammar mistakes. Additionally, scan all received attachments with your anti-malware program. Also, avoid visiting unsecured third-party networks, use only original services, and pay attention to all the products that you are pending to download.

While we highly discourage it, those who do not see another choice might want to risk it, although it is unknown if file decryption will be successful. Nevertheless, you should rather remove Masodas ransomware first and then apply alternative recovery solutions.
