New CryptoShield 1.1 Ransomware – How Does It Infect

Deception is the key to a successful infection and the people behind this iteration of CryptoShield 1.1 ransomware know this. This is why they use cunning e-mails to deceive users who are inexperienced into opening the files encrypted by this iteration of the ransomware.

These type of specific e-mails may contain either an embedded URL or an e-mail attachment in a .ZIP archive. These attachments may pass through most of the antivirus blockers on the e-mail platforms, because they are hidden with an obfuscation software.

Not only this, but the e-mails are created to resemble different companies or respectful organizations such as:

  • Banks.
  • FedEx.
  • Amazon.
  • E-bay.
  • AliExpress.
  • LinkedIn.

These e-mails may present the malicious attachment as an invoice, bill of arrangement and other types of files along with messages that prompt the quick reaction from the user, like a request to urgently open the attachment. This results in the virus successfully infecting the computer from which the attachment is opened.

After infection, the malicious attachment infecting with CryptoShield may connect to the remote distribution site from which the payload of CryptoShield 1.1 ransomware is downloaded.Independent malware researcher Karsten Hahn
(@struppigel) has tweeted the threat’s malicious executable with a very low detection ratio on 3 February, 2017:

CryptoShield Ransomware – Encryption and Ransom

After having already infected the computer, the CryptoShield 1.1 ransomware virus gets right down to business. The ransomware aims to perform multiple activities on the compromised computer. For once, it begins to modify the Windows Registry Editor, so that the malicious files run on Windows boot up. The usually targeted registry keys for this are the Run and RunOnce subkeys. But the virus may also drop it’s ransom note in the %Startup% folder.

This is not all, however. Bear in mind that CryptoShield 1.1 ransomware is a threat like no other. This is why, the virus may also touch specific system files that will allow it to control the processes in Windows Task manager. This gives the CryptoShield virus the power to discontinue database processes and other critical Windows Processes. These actions may allow it not only to encrypt videos, music, documents, and other important files, but to encrypt whole databases as well.

For the file encryption, CryptoShield 1.1 ransomware has so far used the RSA cipher. The encryption procedure happens by replacing bytes of the files with symbols belonging to the encryption algorithm. After encryption takes placed, the files are no longer able to be opened and they appear corrupt. Similar to the 1.0 version, the files carry the .cryptoshield file extension:

Another activity which CryptoShield 1.1 ransomware may perform after the encryption is issue administrative commands to delete shadow copies from the infected computer. One of those commands may be the vssadmin command in administrative mode.

To make sure it’s presence is known, CryptoShield 1.1 ransomware drops a ransom note. This ransom note not only aims to stress the seriousness of the situation but also makes sure the user is completely aware of what the situation is. The ransom note also contains instructions on paying a hefty fee to the cyber-crooks behind this CryptoShield 1.1 variant.

CryptoShield Ransomware – Remove and Try to Decrypt Files

As a bottom line, this iteration of CryptoShield 1.1 has some very interesting changes, primarily in how it is hidden from antivirus programs. With it, we see that cyber-criminals are also keeping up with the latest technologies to ensure their profits from online extortion. In case you have fallen to be a victim of CryptoShield 1.1 ransomware, advises are not to pay any ransom to cyber-criminals.
