This Ransomware Improves Your PC’s Performance. Initially. [fossbytes]

We recently told you about the highly dangerous Lockergoga Virus, which caused Havoc in the industrial complexes. Well, there is a new malware called vxCrypter ransomware in the digital space and it will encrypt your files along and ‘improve’ your PC’s performance.
Vccrypter is based on an unfinished, old ransomware called vxLock that utilized Advanced Encryption Standard (AES) and Rivest-Shamir-Adleman or RSA algorithm to encrypt files.
How does VxCrypter Ransomware work?
The VxCrypter keeps track of the SHA-256 of every file. An SHA-256 is an algorithm that changes data into a fixed fingerprint. Every file has a unique SHA-256 fingerprint, so a file’s copy will have the same SHA-256 code.
VxCrypter Ransomware deletes files with an identical SHA-256 code, essentially clearing up space on your PC and improving performance. It does so to increase encryption speed.
So while the affected users will think of the performance increase as something beneficial in the background, the ransomware will encrypt all the files in the system even faster. Some of the most common file extensions targeted by the ransomware include .txt, .docx, .xls, .ppt, .zip, .xml, .wmv etc.
