What is STOP ransomware? And how does it carry out its attack?

STOP ransomware is a file-encrypting virus that first emerged in December last year and was previously known as SUSPENDED ransomware. Apparently it’s back with its new and improved version and is currently targeting computer users at the time of writing. Just like its predecessor, the moment STOP ransomware infiltrates a system, it will scan the computer for certain file types to encrypt such as:

.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

STOP ransomware uses a combination of AES and RSA 1024 ciphers in encrypting files. Later on, after the encryption, the crypto virus appends the .STOP extension in every file to mark them. Once it is done encrypting and marking the targeted files, STOP ransomware will deliver a ransom note named “!!! YourDataRestore !!!.txt” which contains the following message:

“All your important files were encrypted on this PC.

All files with .STOP extension is encrypted.

Encryption was produced using unique private key RSA-1024 generated for this computer.

If you are one of the victims of STOP ransomware, unfortunately, there is no way to decrypt the files for free YET. So you have to be patient and use whatever backup copies you have for the meantime until a free decryptor is available.

How does STOP ransomware disseminate its malicious payload?

Malicious spam emails remain to be the distribution used by STOP ransomware, just like its previous version. With the help of social engineering developers of STOP ransomware and other cyber crooks trick users into opening obfuscated attachments and installing the malware like STOP ransomware into the system.

Follow each one of the steps laid out below for successful elimination of STOP ransomware from your computer.

Step 1: Launch the Task Manager by simply tapping Ctrl + Shift + Esc keys on your keyboard.

Step 2: Under the Task Manager, go to the Processes tab and look for any suspicious-looking process which takes up most of your CPU’s resources and is most likely related to STOP ransomware.

Step 3: After that, close the Task Manager.

Step 4: Tap Win + R, type in appwiz.cpl and click OK or tap Enter to open Control Panel’s list of installed programs.

Step 5: Under the list of installed programs, look for STOP ransomware or anything similar and then uninstall it.

Step 6: Next, close Control Panel and tap Win + E keys to launch File Explorer.

Step 7: Navigate to the following locations below and look for STOP ransomware’s malicious components such as [random name].exe and !!! YourDataRestore !!!.txt and other suspicious files, then delete all of them.

  • %TEMP%
  • %WINDIR%\System32\Tasks
  • %APPDATA%\Microsoft\Windows\Templates\
  • %USERPROFILE%\Downloads
  • %USERPROFILE%\Desktop

Step 8: Close the File Explorer.

Before you proceed to the next steps below, make sure that you are tech savvy enough to the point where you know exactly how to use and navigate your computer’s Registry.
