How to remove STOP (DJVU) Ransomware and decrypt .stone, .davda, .lanset or .redmat files

STOP Ransomware (a.k.a. DJVU Ransomware) is wide-spread file-encrypting virus-extortionist. This is one of the most dangerous ransomware with high damaging effect and prevalence rate. It uses AES-256 encryption algorithm in CFB mode with zero IV and a single 32-byte key for all files. A maximum of 0x500000 bytes (~5 Mb) of data at the beginning of each file is encrypted. Virus appends .stone, .davda, .lanset or .redmat extensions to encoded files. Infection affects important and valuable files. These are MS Office documents, OpenOffice, PDF, text files, databases, photos, music, video, image files, archives, application files, etc. DJVU Ransomware does not encrypt system files, to make sure Windows operates correctly and users are able to browse internet, visit payment page and pay the ransom. STOP Ransomware creates _readme.txt file, that is called "ransom note" and it contains instructions to make payment and contact details.

How to remove STOP (DJVU) Ransomware and decrypt .rectot, .rezuc, .mogera or .skymap files

STOP Ransomware (a.k.a. DJVU Ransomware) is extremely dangerous virus that encrypts files using AES-256 encryption algorithm and adds .rectot, .rezuc .mogera or .skymap extensions to affected files. Infection mostly involves important and valuable files, like photos, documents, databases, e-mails, videos etc. Rectot Ransomware does not touch system files to allow Windows operate, so users will be able to pay the ransom. If the malware server is unavailable (computer is not connected to the Internet, remote hackers's server does not work), then the encryption tool uses the key and identifier that is hard-coded in it and performs offline encryption. In this case, it will be possible to decrypt the files without paying the ransom. STOP Ransomware creates _readme.txt file, that contains ransom message and contact details, on the desktop and in the folders with encrypted files.
