Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Advanced System Repair to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is Shadow ransomware? And how does it implement its attack?
Shadow ransomware is a new variant of the BTCWare ransomware discovered by Michael Gillespie. This new variant appends the .[email]-id-id.shadow extension to all its encrypted files. It targets computers by hacking into poorly protected remote desktop protocol and installs the ransomware manually. Nothing much has changed on this new variant other than the email address given that the victims should contact which is email@example.com.
During its attack, Shadow ransomware uses a strong encryption algorithm in encrypting the files. It usually encrypts user-generated files such as documents, images, audio, videos, databases and more. It also makes changes to the system like creating some registry keys or modifying them so that it can boot on system startup, disable security programs and make other changes in the system. After the encryption it displays the very same ransom note used in BTCWare ransomware such as follows:
“All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail firstname.lastname@example.org
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files. Free decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.) How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click ‘Buy bitcoins’, and select the seller by payment method and price. https://localbitcoins.com/buy_bitcoins Also you can find other places to buy Bitcoins and beginners guide here: http://www.coindesk.com/information/how-can-i-buy-bitcoins/ Attention!
Do not rename encrypted files. Do not try to decrypt your data using third party software, it may cause permanent data loss. Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.”
No matter how threatening the ransom note gets, paying the ransom should not be a part of your options as there are other alternative ways to recover your files without contacting the crooks behind Shadow ransowmare and losing money. But before you recover your files, make sure that you prioritize the removal of Shadow ransomware as more files will be affected if you don’t put a stop on its attack first.
How does Shadow ransomware proliferate?
As mentioned early on, Shadow ransomware proliferates by taking advantage of poor remote desktop service where the crooks intall Shadow ransomware themselves so it is important that you don’t connect a remote desktop server directly to the internet and you must first require a user to use VPN into your network to be able to connect to the remote desktop server. You also have to make sure that you use hard passwords and never reuse the same passwords at multiple sites.
