This technical blog provides the detailed information about Mbed virus including the instruction to recover the files and data encrypted by it. The article is divided in multiple sections that include what is Mbed virus, how it enters in the PC, how it works, how to recover the locked files and how to protect the PC from such ransomware attacks in future.
About Mbed virus
This malware is a file-encrypting infection that damages and locks the important files and folders stored in the infected PC hard-disk. After locking the files, it displays messages on the PC screen asking you to buy the decryption key. It locks the targeted files using a powerful data-encryption cipher which cannot be unlocked without the original decryption key.
Technically, this type of ransomware is categorized as a crypto-virus. It is different from screen-locker ransomware because they don’t lock the screen but rather they encrypt the files stored in the PC hard-disk. In case of screen-locker, you can simply “format” or “clean” the PC and your ransomware is gone and you are able to access your data. However, this case is totally different. Here, your files have been encrypted and a ransom note only appears on the screen when you try to access the locked files without using decryption key.
The ransom note asks you to purchase the decryption key which is stored in the remote server owned by cyber-criminals. This form of ransomware is the most widespread and perilous. Its consequences are very serious because there is always as possibility of permanent data loss. Still, we will try to provide all the details about ransomware within the next few lines to offer our readers the best way to remove this nuisance threat and possible tricks and ways to retrieve the encrypted files and data.
How Mbed virus Works?
After settling down in the targeted PC, it does a quick scan of System hard-disk. It targets the most important files and data that are most used by the users. Within quick time, it encrypts the targeted files and makes it inaccessible. The encrypted files could be your MS Office docs, multimedia files, PDF files and so on. On every locked file, an additional .mbed extension is added. For example, a file named as 1.jpg will get changed to 1.jpg.mbed. when you access the encrypted file, the ransom note appears on the screen.
What does Ransom Note Demands?
The note contains the basic information like what happened to the file, how it got encrypted and how it can be recovered. Its main focus is to convince you for paying the ransom money. In order to win your trust regarding the working of decryption tool, it agrees to decrypt 1-2 files of your choice for free. It is true that the encrypted files can only be accessed now with the decryption tool which is presented in the cyber-criminals server. According to the ransom note, if the victims make the request payment following the provided instructions, they will receive the decryption key. However, all these claims are spam because the cyber-criminals doesn’t provided the original decryption key even after receiving the complete payment. This is a spam and you will end up losing your money and time if you follow the instructions provided in the ransom note.
Even if the key are sent, they are duplicate in most cases and don’t works. You cannot expect any refund them because you don’t know their real identity. They demand the money to be paid in crypto-currencies such as “Bitcoins” in the provided wallet address.
How to Remove Mbed virus and Recover Encrypted files?
The first step that should take after realizing the ransomware attack is to clean the PC. All the related payloads, scripts, files etc. associated with the malware should be removed. This can easily be done using a powerful anti-malware tool.
Next is to take steps for encrypted file recovery. If have backup files of your important data in some external storage device then you can easily use it to restore. But in situation when there are no backup files and “Volume Shadow Copies” (the temporary backup files created by the OS) is also encrypted by the ransomware, you have to highly rely on a powerful data recovery tool. This will work if the location of encrypted files is not over-written by any new content.
How Mbed virus get Distributed? (Precautionary Measures)
Peer-to-peer file sharing networks promoting freeware and shareware, software bundlers, spam email campaigns and suspicious links and ads are the prime source of malware attack. The software promoted on untrusted platform often contains hidden attachments with them which could be malware payloads. They get installed without any prior notifications or approval. As a targeted victim, you may receive tons of emails with attachments. They cyber-criminals expect you to open the files and malware gets downloaded in the backdoor. So, basically you have to be careful. It is strongly recommended that you strengthen your PC security settings and use a powerful anti-malware tool that provides protection from malware in real-time.
