What is .excuses File Extension ransomware? And how does it carry out its attack?
.excuses File Extension ransomware is a file-encrypting threat set to encrypt files in an infected system. This ransomware threat was first discovered on April 2, 2018. At the time of writing, there is only a handful of information about this threat but according to security experts, it may be created based on the open source platform, HiddenTear and that it targets the following file extensions once it infiltrates a system.
.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: [email protected]
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: [email protected]
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.”
According to researchers, .excuses File Extension ransomware might target Russian speaking users as its ransom note suggests. But that does not necessarily mean that it can’t affect other users from other parts of the globe as well.
