Alma Locker Virus – Infection Spread
Alma Locker ransomware virus is spread through the RIG Exploit Kit, according to the Proofpoint security researcher Darien Huss.
However, that does not exclude the possibility of the ransomware to spread using other methods. It might spread an executable file, placing it inside spam emails as an attachment. Upon opening attachments from such suspicious emails or another place with an unknown origin, your computer can get infected. Social media networks and file-sharing services might also contain such a file somewhere inside them if cybercriminals put them there. Thus, you should always be on a high alert and careful with your clicks, downloads and when you open files. We also could see another Exploit Kit serving the payload file of the ransomware.
Alma Locker Virus – Technical Overview
Alma Locker is a ransomware virus. Darien Huss, a malware researcher, working at Proofpoint security, had discovered it in the wild just one day ago. He also found that Alma Locker ransomware has an active Command & Control server on the TOR network. Note that the ransomware will send the following information to its C&C server:
- AES-128 private decryption key
- file extension put to encrypted files
- user name
- the name of the active network interface
- the system Locale ID (LCID)
- the version of your Operating System (OS)
- the name of your security software
Afterward, Alma Locker ransomware will encrypt files and place a picture as a lock-screen, which is the ransom note. You can see image of it here:
If you follow any of the consecutive links, you will see this page in your browser:
From there you can log in with your unique ID and download the Alma Locker decrypter program. Unfortunately, their site gives an error if you try decrypting some files for free, so you are left with the following decrypter:
There is a period of 120 hours or in other words, five full days, for you to pay the price which is asked. If the condition is not met, the initial price will be increased. The ransom price asked, in the beginning, is 1 Bitcoin and is equal to 580 US dollars. It is not advised to pay these cyber criminals – if you pay them, there is no guarantee that you will unlock your files, and you will only aid them in their criminal activity.
Alma Locker ransomware will search for files to encrypt, which have nearly 90 different file extensions. You could see the full list here:
→.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

All files will get locked with a 128-bit AES encryption algorithm. Also, files and their extension will not be changed, but rather a second extension will be added to them, which has five random characters. As for the victim ID – it is created from the serial number of the C:\ drive and the MAC address of the first network interface. You can follow the discussion in our forum and see an encrypted file’s extension posted by a user there.
You can see that the ransomware uses an executable file named syncli.exe and it is already being detected from a number of security programs based on an analysis from the VirusTotal platform:
It is still not known whether the Alma Locker ransomware virus erases the Shadow Volume Copies of the Windows operating system, but that has a fairly high probability.
