How to remove Magniber virus and restore encrypted files

This article is dedicated to ransomware called Magniber which gets onto customers' machines around the world, and encrypts their files. Here we've assembled full info on Magniber's essence, and the deletion of Magniber from your system. Besides, we'll teach you how to recover the encrypted data, if possible.

Magniber ransomware had penetrated many computers in many countries through basic way: fraud e-mails with viral attachments. Sometimes scammers use zero-day vulnerabilities to infect the system, but major software companies quickly fix them. When infection is done, ransomware scans the hard drive to find the files to be encrypted and their rough worth. Concretely Magniber is using Magnitude Exploit Kit. Nowadays, each new ransomware knows how to encrypt video, text, audio and image files in all most used formats. High attention is paid to businesslike information, since representatives of business are the priority objective for criminals. Ransomware corrupts only files with information, and does not spoil the programs, so that the victim can use his machine to pay the ransom. Encryption is made through famous AES and RSA algorithms, and its complexity is so high that it can't be bruteforced. Such complexity is the reason for impressive efficiency of ransomware in recent years: usual PC operator, even if he has a pretty good knowledge of the PC, won't ever be able to recover the files, and will need to pay the price. The single manner to recover the data is to hack the fraudster's webpage and retrieve the master key. Sometimes it is possible to withdraw encryption keys via faults in viruse's program code. Ransomware asks 0.2 Bitcoins. This amount will be doubled after five days.

The computer knowledge is very significant in our century, as it assists you to defend the laptop from hazardous programs. For encrypting programs this is most relevant, since, unlike normal unwanted programs, when you eliminate ransomware from the PC, the effects of its doings won't vanish anywhere. To protect yourself, you need to understand these three elementary principles:

    • Do not disregard the symptoms that your PC displays. Data encryption is a complicated operation that uses a lot of hardware resources. If you see a noticeable fall in laptop power or notice a suspicious string in the Process Manager, you need to shut down the PC, boot it in safe mode, and run the antivirus. This, if the laptop is really infected, will save a lot of your data.
    • Attentively examine your mailbox, specifically those messages that have attached files. If this message comes from an unknown sender and it notifies about earning some prize, a lost package or anything similar, this could be ransomware. The #2 effective type of fraud messages is a "business letters". summaries, lawsuits, claims, Invoices for goods and services and other sensitive documents don't come accidentally, and you, as a minimum, should know the sender. Otherwise, it is a scam.
    • Do not accept any alterations to the computer, coming from strange programs. The most efficient way of data restoration is the restoration from Shadow Copies, so fraudsters have included the deletion of shadow copies in the default functionality of malware. Anyway, deleting of shadow copies requires admin rights and acceptance from the operator. So, not accepting changes from a weird software at the proper time, you will keep the chances to decrypt all encrypted files for free.

Magniber elimination is not the happy end - it's only a first move from many until the full data restoration. If you get rid of virus, you will not get back the data instantly, it will take more actions written down in the "How to restore encrypted files" part. In case of ransomware we do not provide the hand deletion instruction, since its complexity and the possibility of mistakes is too high for common user. Some viruses can't be removed even through AV-software, and have lots of effective mechanisms of protection. The very effective ransomware defensive technique is the uninstalling of files in event of file recovery or ransomware deletion attempt. To avoid this, follow the instructions under this paragraph.
