Alma Locker Ransomware Description

The Alma Locker Ransomware was discovered in August 20216 by the Proofpoint security researcher Darien Huss. This is a dangerous threat that has initiated several attack campaigns since its inception a few months ago.

Most of the instances of the Alma Locker ransomware were found to contain bugs in the source code. The developers were able to release updated versions that had active connections with the remote malicious C&C servers on the TOR network. They use an encrypted connection to safeguard the connection.

Upon infection the Alma Locker generates a random 5-character file name extension that is applied to the target user files. Each infected system also is given a unique 8-character victim ID. It is made up of the serial number of the C: system partition and the MAC address of the primary attached network interface. The used encryption cipher is AES-128

The ransomware searches all attached hard disks and partitions for files that it can affect. The following file name extensions are targeted:

.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

While the encryption process is engaged the Alma Locker ransomware also has an exceptions list – if the following strings are found, then the files and folders will not be affected:

system volume information
program files
program files (x86)
internet explorer
local settings

After all files have been encrypted and locked by the Alma Locker ransomware, the virus generates a ransom note that contains the links to the TOR payment gateway. In addition the hacker operators of the threat have also added a time limit to blackmail the user into paying the ransom sum – usually 1 Bitcoin.

The following files are created as the ransom note:

  • Unlock_files_[random_extension].html
  • Unlock_files_[random_extension].txt

The Alma Locker gateway also lets the users decrypt some of their files for free to test to make sure that by paying they can get restore their files.
