What is Satyr ransomware? And how does it carry out its attack?

Satyr ransomware is a file-encrypting virus that was recently spotted a few days ago. This new ransomware threat carries out its attack just like a typical ransomware infection – once it is able to infiltrate a system, it will download and install more malicious files in the system. It also uses the Command Prompt with administrator privileges to execute commands in the system. After that, Satyr ransomware will scan the system looking for files to encrypt. It may encrypt files with the following extensions:

.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2

Satyr ransomware uses both the AES and RSA ciphers in locking targeted files. As soon as it completes the data encryption process, this crypto-malware drops its ransom note explaining to its victims what happened to their files. Here’s the content of the ransom note:

“Security tips

All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us the Telegram: https://t.me/tony_montana10928 or @tony_montana10928 and send personal ID KEY: <…>

For Decrypt Your Personal Files Send 0.018 BTC to this address: <…>

You have to pay for decryption in Bitcoins. The price depends on how you write us. After payment we will send you decryption tool that will decrypt all your files”

As you can see, the crooks behind Satyr ransomware wants its victims to contact them via Telegram messenger once the payment is sent that amounts to 0.018 BTC – approximately $147.5. However, contacting these crooks and paying the ransom is definitely not recommended.
