.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

Once it finds the files it’s been looking for, .excuses File Extension ransomware will encrypt them using a strong encryption algorithm and append the “.excuses” extension to each one of the encrypted files. Following data encryption, this crypto-malware drops a file named “MESSAGE.txt” containing the following text written in Russian:

“Приобрести декриптор можно до 02.04.2018

Запросить стоимость: excuses@protonmail.com

В ТЕМЕ письма укажите ваш ID: [redacted numbers]

Письма без указания ID игнорируются.

Убедительная просьба не пытаться расшифровать файлы сторонними инструментами.

Вы можете их окончательно испортить и даже оригинальный декриптор не поможет.

Заявки обрабатываются автоматической системой”

Here’s the ransom note translated from Russian to English:

“You can buy the decryptor before 04/02/2018

Request cost: excuses@protonmail.com

In the subject of the letter, indicate your ID: [redacted numbers]

Letters without an ID are ignored.

Please do not try to decrypt files with third-party tools.

You can ruin them entirely and even the original decryptor will not help.

Applications are processed by an automated system.”
