Guide to Remove Paradise Ransomware

Paradise Ransomware is a file-encrypting virus that surfaced to lime-light for the first time in September 2017. For the past two years, it has been encrypting user’s files using highly-complex Encryption Algorithm, RSA-1024.

Paradise Ransomware -threat summary

In addition to that, Paradise Ransomware is being aggressively distributed as a Ransomware as a Service (RaaS) to the interested affiliates. The developers of Paradise File virus allow the affiliates to customize RaaS by changing ransom amount, contact e-mail address & distribution techniques.

By doing so, developers avoid shouldering the task of malware distribution & use the affiliates to propagate Paradise Ransomware. They generate hefty illicit revenue by charging a certain percentage of ransom amounts from the affiliates.

Some of the common spread techniques of Paradise Ransomware include infected spam e-mail attachments, malware-laden websites & suspicious links.

Once the system is infected, Paradise file virus appends the targeted file names with .paradise extension. However, paradise Ransomware received multiple updates from its developers in the span of two years. Some of the extensions that Paradise variants use are .b1, .sambo, .p3rf0rm4, .b29, .prt, .sell, .ransom & .logger.

Once files are encrypted, Paradise Ransomware drops ransom-demanding text notes on the victim’s system. The demanded ransom amount varies from $500 to $1500 (in bitcoins).

Let us understand what more Paradise Ransomware is capable of doing of & how can one prevent falling victim to this nasty threat.

Threat Behavior of Paradise Ransomware

Paradise Ransomware is a devious crypto-virus that encrypts the files using complex Encryption Algorithms such as RSA-1024 & RSA-2048. Not only this, it is also being sold as Ransomware as a Service (RaaS) on the dark web to the interested affiliates.

The prime method of its distribution is Infected Spam E-mail Attachments. A mere click on the malicious Zip attachment unpacks Paradise Ransomware & installs it on the system.

Paradise Ransomware Note 1

Once infected, Paradise employs Encryption Algorithms to encrypt targeted file extensions. It is capable of encrypting user-generated files such as:

  • Images (.jpg, .jpeg, .raw, .tif, .gif, .png)
  • Audio Files (.mp3, .aif, .iff, .m3u, .m4u, .mid, .mpa, .wma, .ra, .avi, .mov, .mp4)
  • Video Files (.3gp, .mpeg, .3g2, .asf, .asx, .flv, .mpg, .wmv, .vob)
  • Document files (.docx, .doc, .odt, .rtf, .text, .pdf, .htm, .ppt)
  • Backup Files (.bck, .bckp, .tmp, .gho)

The encrypted files are appended with-

  • Affiliate Id
  • Affiliate E-mail Address
  • .paradise Extension

For example: A file named presentation1.ppt might be renamed as “presentation1.pptid-xxxxxxxx.[ info@decrypt.ws].paradise”.

Besides encrypting, it deletes shadow copies of files, thus, restricting the users from restoring them.

Use of Paradise Ransomware as a RaaS

According to the sources, Paradise Ransomware is being distributed as a Service on the dark web since September 2017. Thus, it has enabled interested affiliates to lock the networks of the victims & hold them for hefty ransom amount.

However, cyber-security analysts do not have much relevant information about Paradise RaaS platform. It is being managed by anonymous personalities on the Dark Web.

Paradise Ransomware - Targeted Files

Initial Paradise Attacks were observed in various parts of Western Europe & United States. The RaaS mainly targeted Windows OS & ran as “DP_Main.exe” on the infected system.

The developers of Paradise RaaS allow the third-party affiliates to customize & distribute various strains of Paradise Ransomware. In return, the developers receive a certain percentage of the ransom amount & generate huge revenue. One of the well-known variants of Paradise RaaS is TeslaWare.

Some of the extensions of the updated variants of Paradise RaaS are:

  • [blackblackra@tuta.io].b1
  • .sambo
  • __{babyfromparadise666@gmail.com}.p3rf0rm4
  • [yourencrypter@protonmail.ch].b29
  • 0.0.0.1{paradise@all-ransomware.info}.prt
  • {help@badfail.info}.paradise
  • .sell
  • .ransom
  • .logger
  • .CORP
  • VACv2

Details of Ransom Note & Ransom Amount for Paradise Ransomware

Following the successful encryption of the targeted files, Paradise Ransomware drops three text files on the victim’s desktop. These include:

  • PARADISE_README_paradise@all-ransomware.info.txt”
  • txt
  • txt
  • & a ransom note – #DECRYPT MY FILES#.txt

The file named Files.txt contains details of the encrypted user file extensions. The second file named Failed.txt has the list of files that could not be encrypted due to some reason.

Paradise Ransomware - Ransom Note

The most important file is #DECRYPT MY FILES#.txt, which contains ransom-demanding message from the cyber-crooks. The note describes that the files are encrypted & could not be restored without a decryption key. It further suggests the victims to contact the hackers on the provided e-mail address in order to restore the encrypted files.

Encryption Algorithm, RSA-1024 employed by Paradise Ransomware to encrypt the files generates two private keys – public encryption key & private encryption key. These keys are vital for decrypting the files. Since these keys are stored on hacker’s remote server, they demand hefty ransom amount in exchange of the keys.

While ransom amount (to be paid in Bitcoins) is not specified, it typically ranges from $500 to $1500.

Claims Made by Hackers & its Authenticity

Besides, hackers permit the victims to send any three files (up to 1 MB of size altogether) on the provided e-mail address. The developers offer to decrypt these files for absolutely free of charge & send it back to the victims as a “guarantee” of decryption.

You might wonder if cyber-crooks could be trusted! Well, cyber-security analysts suggest not contacting the hackers. In most of the cases, hackers ignore responding to victims after receiving ransom amount.

Paying the ransom amount doesn’t guarantee decryption of files in any way. Instead, the users lose their money & data permanently and support cyber-crooks in their wicked motives.

Therefore, we do not support reaching out to hackers & paying the ransom.

While no tools are available to crack RSA cryptography as for now, we suggest restoring the system & encrypted files from a backup.

Distribution Techniques of Paradise Ransomware

The cyber-criminals use various strategies for malware distribution which include –

  1. Software Bundling: Software bundling is the process in which a malicious program is distributed with other free software, to get an unnoticed entry into your computer system. When a user installs a free application, the malicious programs gains a front door entry with the free application, the user has downloaded. Thus, it is a good idea to keep an eye on the installation screens while installing these free applications.
  2. Infected Storage Devices: Your system can also get infected by using removable media such as USB hard drives and jump drives without scanning them with an anti-virus.
  3. Spam Emails – Spamming is the most economic and common method used for the distribution of such malware. The targeted users get genuine looking emails which contain .doc, .txt, and other similar attachments. These attachments can be named as anything which can grab the user’s attention and triggers him/her to open the attachment. As soon as the user opens this attachment, the malware infects the user’s computer system.
  4. Malicious Websites or Malevolent Advertisements: The malicious websites are the ones which are created just for promoting the malware infections. Such websites include but are not limited to porn sites, torrent sites and other free downloading platforms. By visiting such websites, the adware infects the user’s computer without permission. Fake advertisements and updates like Flash player and windows updates which ask the user to update to the latest version are a few examples. When the users click on such links, their computer system gets infected. That is why, it is highly recommended to resist clicking on such links. Also avoid clicking on advertisements offering free stuff such as Win an iPhones, cars or free overseas trips etc.
