What is Alma Locker ransomware?
Alma Locker is a variant of ransomware infection. It affects all current versions of Windows operating systems such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This virus uses an AES-128 encryption mode to eliminate the possibility of brute force a key, which will allow to decrypt all encrypted files.
When the virus infects a computer, it uses system directories to store own files. To run automatically whenever you turn on your computer, Alma Locker ransomware creates a registry entry in Windows: sections HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce.
Immediately after the launch, the virus scans all available drives, including network and cloud storage, to determine which files will be encrypted. The ransomware uses the file name extension, as a way to define a group of files that will be subjected to encrypting. Encrypted almost all types of files, including common as:
.1cd, .3ds, .3gp, .accdb, .ape, .asp, .aspx, .bc6, .bc7, .bmp, .cdr, .cer, .cfg, .cfgx, .cpp, .cr2, .crt, .crw, .csr, .csv, .dbf, .dbx, .dcr, .dfx, .dib, .djvu, .doc, .docm, .docx, .dwg, .dwt, .dxf, .dxg, .eps, .htm, .html, .ibank, .indd, .jfif, .jpe, .jpeg, .jpg, .kdc, .kwm, .max, .mdb, .mdf, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdf, .pef, .pem, .pfx, .php, .png, .pps, .ppt, .pptm, .pptx, .psd, .pst, .pub, .pwm, .qbb, .qbw, .raw, .rtf, .sln, .sql, .sqlite, .svg, .tif, .tiff, .txt, .vcf, .wallet, .wpd, .xls, .xlsm, .xlsx, .xml
Once a file is encrypted, its extension will be changed. Next, the virus creates the files named “Unlock_files_[EXTENSION].txt”. This file contain instructions on how to decrypt all encrypted files. An example of the instructions:
Your files are encrypted!
Your ID: *****
You can unlock [EXTENSION] files using these instructions:
