Browsing the web is always entertaining, but it can become dangerous when a dreadful infection like ransomware or any other form of malware enters into your computer from a click on a high-risk site like gambling, torrent, porn, etc.

Though the internet looks secure, with the increase in cyber attacks, spam emails, malicious documents, etc. sometimes it is difficult to trust the web URL on the internet search engine.

Anonymous hackers somehow use various online techniques to leave malicious programs into your computer for impacting the operating system’s performance to a large extent.

One such unwanted program that should never exist in your computer is .Promos Ransomware, designed to encrypt data and files. In other words, it locks down your files, data, online information, etc without user consent.

The ransomware belongs to STOP/Djvu ransomware family. If your documents, music, photos, web pages, etc don’t open normally due to .promos file extension, then your machine is infected and center of cause is this newly found ransomware.

Once launched, it locks all the stored files on a computer, stop drives from functioning normally and blocks the networked drives. It is malicious software that hijacks a whole machine by locking files and other software.

What is Promos Ransomware?

.Promos ransomware is a file-encrypting malware that usually gets inside the system via malicious email and process data encryption. It is a new variant of the ransomware that appends .promos extension.

Like all other ransomware, it is also a file-encrypting malicious code that hijacks your computer to encrypt photographs, music records, business reports, pdf, docs and all other data only after utilizing file lock and encryption cipher techniques like AES/RSA.

To lock any file, the ransomware adds the .promos extension. For example, filename.jpg encrypts to filename.jpg.promos.

Typically, it spreads after it hacks into remote network computers and desktop services. It should also be noted that this dangerous ransomware encrypts mapped network drives, unmapped networks, host drives and shared virtual machines.

On clicking any locked file, a ransomware  _readme.txt opens demanding $980 in bitcoin. Like every other note, the message tells users to pay ransom in bitcoins to get back the access to all the encrypted files.


Eventually, once the payment is done the ransomware developers in the note claims to free your system unharmed. However, from the reports by cybersecurity expert, this claim was found misleading the victims of ransomware.

Typical of like ransomware, this claim is false and once the payment is done, the cyber attackers demand more money rather than leaving the system. We suggest you to never make payment and must find a way to delete .promos ransomware files.

How to decrypt Promos Ransomware?

It is nearly impossible to recover all the locked files as the encryption algorithm is strong and runs on private keys of malicious programmers. Therefore, as of now, it is quite notable that forging out any decryption key and tool is not realistic.

Moreover, to make any decryption tool it is important to reverse engineer the program code of ransomware’s encryption mechanism. Unfortunately, more time is required to break down the encryption mechanism.

As per security experts, presently .promos ransomware decryptor tool is not present and is yet to be developed. Since there is no decrypt tool to recover your files, we recommend taking some preventive measures.

NOTE: Do not belive cyberattackers that aks you to pay money for decryptor tool because .promos file recovery via this isn’t possible and you would lose your money too.
