How CryptoJacky Ransomware Can Infect the Computer

Like most crypto viruses CryptoJacky is highly believed to be part of spam email campaigns. So the malicious payloads are possible to be archived to a ZIP file or inserted into the code of an ordinary document. The infected files are most likely to be attached to an email which message commonly is written in a misleading way that invites you to interact with the attached content. If you download the file and open it, CryptoJacky ransomware infection will start taking control of your system and data. Be alert because cyber criminals are getting better at impersonating legit services that are usually part of our everyday life.
Malicious or corrupted web links are also possible to be part of criminals’ schemes for CryptoJacky ransomware distribution. Such suspicious links might be presented in:

  • Spam emails – in the text body or the form of a button
  • Malicious advertisements – banners, pop-ups, text, image, and even video based ads
  • Spammed comments on websites with poor spam filters and configuration
  • Shares and comments on social media sites from compromised profiles
  • Personal messages from discredited social media profiles
Security tip: Whenever you doubt the safety of a file or link, you can first check it with free online malware scanning services like ZipeZip and VirusTotal. The results will help you to decide whether it is a good idea to interact further with the suspicious content or avoid its opening in order to keep safe your system.

CryptoJacky Ransomware Infection – Features and Impact

The original name of the threat is cryptoJacky v2.0, and the file cryptoJacky-setup.exe is the one that starts the infection process once it runs on the computer. CryptoJacky is a crypto ransomware. Thus it scans the system for particular file types in order to encrypt them via strong encipher algorithm. Whenever there is a match with the file types included in its target list, CryptoJacky utilizes AES algorithm to encrypt the file and appends a specific extension at the end of its original name.

There is no information about the exact file types that are in the scope of CryptoJacky malevolent impact yet. However, it is most likely that it is developed to corrupt commonly used files like MS Office documents, text files, images, videos, music, archives, etc.

As reported the encryption process of CryptoJacкy ransomware is carried out via a file called aescrypt.exe that is dropped on the Desktop. Probably the file is activated automatically via modifications in the Windows registries.

The extortionists offer a data decryption solution in exchange of the ransom amount of 250 EUR in bitcoins. Their message comes in the form of ransom notes that are also dropped on the Desktop. These files are:

  • ransom-information.lnk
  • ransom-instructions.lnk
  • ransom-payment.url

Two of them contain the following texts:

  • ransom-information.lnk

Ransom_ph! ha detectado actividad inmoral en sus hábitos online y/o en su equi- po, siendo así me he visto en la obligación de retener sus archivos personales. Si usted desea comprar la contraseña para recuperar el control de los mismos, sirva- se seguir las intrucciones cliqueando en el archivo “ransom-instructions” que se- rá creado en el escritorio para tal fin. Nota: son tres íconos los que se crearán, si alguno no apareciera, por favor haga click con el botón derecho del mousey seguidamente en actualizar.

  • ransom-instructions.lnk

Para comprar la contraseña haga click en el ícono “ransom-payment”. Una vez abierto el link seleccione arriba del cuadro “list” y luego en la columna de la izquierda la opción con la que va a pagar, en la derecha seleccione bitcoins. Cliquee “Find the best rate”.

Una vez hecho el pago hágamelo saber enviandome un correo a la siguiente dirección:
[email protected]
Siendo así, le será enviada la contraseña.
Haga click en “ransom of files” e ingrésela.-

The language of the notes is Spanish, so we suppose that the first attack waves will be targeting Spanish computer users. However, the malicious campaigns are probably to be expected worldwide.

The instructions include text that urges victims to make the ransom payment of 250 EUR in bitcoins in order to receive the decryption key. Once victims transfer the money, they are navigated to contact cyber criminals via sending them an email to [email protected]. Once the decryption key is received, it should be entered in the displayed field after clicking the “OK” button displayed on the ransom-instructions.lnk file.
