Although, this ransomware was identified on 19^th January 2017. The malware does not features a plethora of distinct properties as compared to other variants of ransomware based on the HiddenTear project, such as MafiaWare Ransomware and the HiddenPeach. Malware researchers that worked with the samples of CryptoShadow Ransomware reveal that the infection may be introduced to the targeted machine by using corrupted text documents.

“iexplorer.exe” : Primary Executable of CryptoShadow Ransomware

Cyber Security experts revealed that there is an executable file named as “iexplorer.exe” which served as the encryption payload for this ransomware threat. The developers of CryptoShadow Ransomware made “iexplorer.exe” executable file that looks like as a shadow instance of the Internet Explorer by Microsoft. This happens when the system users decides to check running processes onto the machine while the CryptoShadow malware is active.

Investigators report that the malware comes with an unique RSA and AES ciphers. The AES cipher is used to encrypt the files stored on the system and append the file extension with ‘.doomed’. Besides, the RSA cipher is used just after the encryption process is completed. The CryptoShadow Ransomware needs to obfuscate AES key and deliver it over the web to its ‘C&C” servers along with the information about compromised system. It sends parameters like encryption key, victims ID, IP address, active account name and operating system version. After considering the secure encryption procedure powering the ransomware seems appropriate.

Moreover, CryptoShadow Ransomware displays LEER_INMEDIATMENTE.txt which means “Read Completely” ransom note onto the users desktop, where it asks for the ransom money to decode their files. Sadly, malware researchers are currently unable to find the vulnerabilities into the code of this ransomware virus and build a decryption key yet. Computer users may want to place their affected data and files into a large archive and keep a keen eye over the Internet for a possible solution in near future. Meanwhile, you can use the backup copies and archives in order to rebuild you vital data structure.
