Remove FileEngineering Ransomware (.encrypted Files)

FileEngineering ransomware that is based on Python kit according to malware researcher Demonslay335. Since this is a generic file-coder or crypto-virus, the name FileEngineering was based on the phrase often used in the contact address as FileEngineering@rape.lol and FileEngineering@elude.in. FileEngineering ransomware was developed simply to lock victim’s files by applying an advanced encryption method and also saves the original file size as ASCII in the first 16 bytes of the file.

How FileEngineering Ransomware Infects the Computer?

Social engineering attack, web injectors, pirated software, malicious applications, Trojan downloader, malicious advertisements, and phishing emails are just some method that helps the global distribution of FileEngineering ransomware. Hence, mass mailing campaign seems to have gotten most of the victims since it can cleverly disguise as a valid document file. The email commonly reaches the inbox as a message sent by a prominent organization. It converses about business deals, parcel delivery, shipping instructions, payment terms, and similar subjects. The message was crafted carefully to influence the recipient into opening the attached file, claiming that it holds the critical information. As soon as user executes the email attachment, FileEngineering ransomware initializes the infection.

Malicious file installers comes as second most assistive technique in the distribution of FileEngineering ransomware. Attackers are embedding the virus to malicious repackage setup file and once computer users run the installation, FileEngineering ransomware starts to contaminate the computer. If not FileEngineering ransomware, other similar threat such as Slgh, ZIN, or Lockbit is incorporated to the infected file installer.

FileEngineering Encryption Attack

Like the majority of ransom virus, FileEngineering ransomware encrypts the target data with an advanced encryption algorithm to make it useless. At the same time, this virus appends the data sets of strings and .encrypted file extension. Therefore, the common file image.jpg will become image.jpg.id=[672635FG]Email=[FileEngineering@rape.lol].encrypted. Then, it will leave a note telling victims to contact the attackers at FileEngineering@rape.lol or FileEngineering@elude.in if they want to secure the decryption tool. Here is a message from the ransom note.

Hello
I am a security engineer.
I noticed that your system security is very weak and I hacked it.
And all your files are encrypted!
I can return your files for a fair amount of Bitcoin and also tell you your security vulnerabilities.
Send an email to this address : FileEngineering@rape.lol
And write this ID in its subject : (unique id)
If I did not reply to you within 12 hours, send an email to : FileEngineering@elude.in
There is no way to decrypt your files, so pay attention to the following:

Never change the name of your files, you may have problems with the decrypt
Never try to decrypt files with another tool
You may have a backup of your files but you will never notice your system bugs and I can hack your system again
