Tips to Remove PROM Ransomware – Security Tips


PROM ransomware is a form of malware that employs encryption to hold the victim’s files hostage until a ransom is paid. It prevents its victims from accessing their system or data and demands ransom payment for decryption. Continue reading this post to know how to remove it from your computer without too much hassle.

What is PROM Ransomware? 

PROM is the name of a malicious program classified as ransomware. After successfully infiltrating the targeted system, it uses RSA and AES encryption algorithms to lock all types of user data (e.g., photos, videos, audios, work documents, archives, etc.) and demands a huge sum of money in the form of Bitcoin cryptocurrency to restore access. 

During the encryption process, it appends the “.PROM[prometheushelp@mail.ch]” extension to the name of each compromised file. For example, it renames a file originally named “1.mp3” to “1.mp3.PROM[prometheushelp@mail.ch]”, “2.mp3” to “2.mp3.PROM[prometheushelp@mail.ch]”, and so on.

Once the files are encrypted, PROM ransomware generates two ransom notes (“RESTORE_FILES_INFO.hta” and “RESTORE_FILES_INFO.txt”) to provide victims with details, such as the price of a decryption key, email address of ransomware authors, payment instructions, etc.

PROM Ransomware: Distribution Techniques

Over the last couple of decades, cybercriminals have used and developed several diverse and sophisticated ways to infect users with an array of malware strains. PROM ransomware is no different in the sense that it employs most of the same tactics used in other malware attacks.

  • MalSpam or malicious spam
  • Malvertising or malicious advertising
