What is File-Locker ransomware? And how does it implement its attack?
File-Locker ransomware is a file-encrypting virus which belongs to the HiddenTear ransomware group. It targets users from Korea based on its ransom note which is written in Korean. According to security experts, it reaches the targeted system as a malicious executable file named File-Locker Ransomware.exe which is responsible for implementing the attack on the infected computer.
File-Locker ransomware utilizes the AES encryption algorithm in encrypting files with the following file formats:
.txt, .doc, .docx, .xls, .index, .pdf, .zip, .rar, .css, .lnk, .xlsx, .ppt, .pptx, .odt, .jpg, .bmp, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml, .psd, .bk, .bat, .mp3, .mp4, .wav, .wma, .avi, .divx, .mkv, .mpeg, .wmv, .mov, .ogg, .java, .csv, .kdc, .dxg, .xlsm, .pps, .cpp, .odt, .php, .odc, .log, .exe, .cr2, .mpeg, .jpeg, .xqx, .dotx, .pps, .class, .jar, .psd, .pot, .cmd, .rtf, .csv, .php, .docm, .xlsm, .js, .wsf, .vbs, .ini, .jpeg, .gif, .7z, .dotx, .kdc, .odm, .xll, .xlt, .ps, .mpeg, .pem, .msg, .xls, .wav, .odp, .nef, .pmd, .r3d, .dll, .reg, .hwp, .7z, .p12, .pfx, .cs, .ico, .torrent, .c
When it’s done encrypting the files, it appends the .locked extension and then creates a ransom note named Warning!!!!!!.txt which is written both in Korean and English demanding its victims to pay 50,000 won in Bitcoins for the recovery of the encrypted files. What’s strange is that the Bitcoin address indicated is for an account which is seized as a part of the Silk Road takedown. The following context is the ransom note of File-Locker ransomware:
