AES_NI is a ransomware strain that first appeared in December 2016. Since then, we’ve observed multiple variants, with different file extensions. For encrypting files, the ransomware uses AES-256 combined with RSA-2048.
The ransomware adds one of the following extensions to encrypted files:
.aes_ni
.aes256
.aes_ni_0day
In each folder with at least one encrypted file, the file "!!! READ THIS - IMPORTANT !!!.txt" can be found. Additionally, the ransomware creates a key file with name similar to: [PC_NAME]#9C43A95AC27D3A131D3E8A95F2163088-Bravo NEW-20175267812-78.key.aes_ni_0day in C:\ProgramData folder.
The file “!!! READ THIS - IMPORTANT !!!.txt” contains the following ransom note:
Alcatraz Locker is a ransomware strain that was first observed in the middle of November 2016. For encrypting user's files, this ransomware uses AES 256 encryption combined with Base64 encoding.
Encrypted files have the ".Alcatraz" extension.

BTCWare is a ransomware strain that first appeared in March 2017. Since then, we observed five variants, that can be distinguished by encrypted file extension. The ransomware uses two different encryption methods – RC4 and AES 192.
Encrypted file names will have the following format:
foobar.docx.[sql772@aol.com].theva
foobar.docx.[no.xop@protonmail.ch].cryptobyte
foobar.bmp.[no.btc@protonmail.ch].cryptowin

CryptoMix (also known as CryptFile2 or Zeta) is a ransomware strain that was first spotted in March 2016. In early 2017, a new variant of CryptoMix, called CryptoShield emerged. Both variants encrypt files by using AES256 encryption with a unique encryption key downloaded from a remote server. However, if the server is not available or if the user is not connected to the internet, the ransomware will encrypt files with a fixed key ("offline key").
Important: The provided decryption tool only supports files encrypted using an "offline key". In cases where the offline key was not used to encrypt files, our tool will be unable to restore the files and no file modification will be done.
Update 2017-07-21: The decryptor was updated to also work with Mole variant.
Encrypted files will have one of the following extensions: .CRYPTOSHIELD, .rdmk, .lesli, .scl, .code, .rmd, .rscl or .MOLE.
The following files may be found on the PC after encrypting files:

EncrypTile is a ransomware that we first observed in November of 2016. After a half-year development, we caught a new, final version of this ransomware. It uses AES-128 encryption, using a key that is constant for a given PC and user.
The ransomware adds the word “encrypTile” into a file name:
foobar.doc -> foobar.docEncrypTile.doc
foobar3 -> foobar3EncrypTile
The ransomware also creates four new files on user’s desktop. Names of these files are localized, here are their English versions:
While running, the ransomware actively prevents the user from running any tools that might potentially remove it. Refer to the blog post for more detailed instructions how to run the decryptor in case the ransomware is running on your PC.
FindZip is a ransomware strain that was observed at the end of February 2017. This ransomware spreads on Mac OS X (version 10.11 or newer). The encryption is based on creating ZIP files - each encrypted file is a ZIP archive, containing the original document.
Encrypted files will have the .crypt extension.
After encrypting your files, several files are created on the user’s desktop, with name variants of: DECRYPT.txt, HOW_TO_DECRYPT.txt, README.txt. They are all identical, containing the following text message:
Special: Because AVAST decryptors are Windows applications, it is necessary to install an emulation layer on Mac (WINE, CrossOver). For more information, please, read our blog post.

Gandcrab is one of the most prevalent ransomware in 2018. On 17. October 2018, Gandcrab developers released 997 keys for victims that are located in Syria. Also, in July 2018, FBI released master decryption keys for versions 4-5.2. This version of decryptor utilises all these keys and can decrypt files for free.
The ransomware adds multiple possible extensions:
.GDCB,
.CRAB,
.KRAB,
.%RandomLetters%
foobar.doc -> foobar.doc.GDCB
document.dat -> document.dat.CRAB
document.xls -> document.xls.KRAB
