Iwan Ransomware (a.k.a. STOP Ransomware or Djvu Ransomware) is wide-spread file-encrypting virus-extortionist. This is one of the most dangerous ransomware with a high damaging effect and prevalence rate. It uses the 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. The virus appends .iwan extensions to encoded files. The 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 the internet, visit the payment page and pay the ransom. Iwan Ransomware creates _readme.txt file, that is called "ransom note" and it contains instructions to make payment and contact details. The virus places it on the desktop and in the folders with encrypted files. Developers offer following contact details: manager@mailtemp.ch and managerhelper@airmail.cc.

If your files recently got .lqqw extensions, that means your PC is infected with encryption virus called Lqqw Ransomware (part of STOP Ransomware or Djvu Ransomware family, called so because first versions of virus of this type appended .djvu extension). This is a very widespread and actively distributed malware. Ransomware initially used the AES-256 encryption algorithm, and there was no way for decryption. However, if during the encryption process infected PC was out of the internet, or connection with a remote server of hackers was interrupted your files can be decrypted, using methods provided below. STOP Ransomware has a ransom note called _readme.txt. In this text file, malefactors give contact information and details on how to make a payment. The virus copies it on the desktop and in the folders with encrypted files. Hackers provide following contacts, e-mails: manager@mailtemp.ch and managerhelper@airmail.cc. To this moment very few developers of ransomware threats were caught by the police (mostly occasionally). They use anonymous servers and cryptocurrency wallets to receive payments and this makes them almost untraceable. Hackers want $980 for decryption and offer a 50% discount if the ransom is paid within 72 hours after the encryption). The unimportant file can be sent to them, to prove that they can decode your data. It is strongly recommended not to pay any money to cybercrooks, because there is no guarantee, that they will send you the decryption tool back. Besides, there is a special tool called STOP Djvu Decryptor from EmsiSoft, that can decrypt files encrypted by Lqqw Ransomware for free.

Recently, experts have observed the epidemic of the virus Efcm Ransomware (also known as STOP Ransomware or Djvu Ransomware). It is an encryption virus, that uses a strong AES-256 encryption algorithm to encrypt user files and makes them unavailable for use without a decryption key. Latest versions of this pest add .efdc extensions to affected files. Efdc Ransomware creates special text file, that is called "ransom note" and named _readme.txt. In this text file, malefactors provide contact details, overall information about encryption, and options for decryption. The virus copies it on the desktop and in the folders with encrypted files. Malefactors can be contacted via e-mails: manager@mailtemp.ch and managerhelper@airmail.cc. Using anonymous TOR servers and cryptocurrency to receive ransom payments makes hackers almost invulnerable, however, due to their own mistakes they get caught from time to time. The price of decryption of this ransomware is set to $980, but it can be reduced by half if paid within 72 hours. This is done to increase the conversion of users, who are ready to pay for the return of their files. Cybercriminals can even decrypt one file for free, to prove to you, that they will send a decryptor and it will work. We strongly advise not to pay any money to them, as there is no guarantee that such dubious personalities will keep promises. Mention also, that there is a special utility called STOP Djvu Decryptor, that can decrypt (or will be able to decrypt in the nearest future) files encrypted by Efdc Ransomware for free.

Orcf Ransomware (aliases: Djvu Ransomware, STOP Ransomware) is extremely dangerous file-encrypting virus, that extorts money in exchange for decrypter. Ransomware utilizes a strong AES-256 encryption algorithm and makes files unusable without a decryption master key. Particular malware in this review appends .orcf extensions to files. As a result, file example.jpg converts to example.jpg.orcf. Orcf Ransomware creates a special text file, that is called _readme.txt, where hackers give contact details, overall information about encryption, and options for decryption. Threat places it on the desktop and in the folders with encrypted files. Cyber-criminals can be contacted via e-mail: manager@mailtemp.ch and managerhelper@airmail.cc. All latest versions of STOP Ransomware, including Orcf Ransomware, use typical behavioral patterns. They use anonymous TOR servers and cryptocurrency to receive ransom payments and that prevents police from tracking them. The cost of decryption is $980, but it can be $490 if victims pay within 72 hours. Cybercriminals even offer to decrypt one file for free, as proof, that files can actually be decrypted. In most cases, Orcf Ransomware encrypts files of each victim with a unique key, however, sometimes when the computer is not connected to the internet (or lost connection) or the hacker's server is not responding, the malware creates an "offline key".
