PLUT ransomware removal instructions

What is PLUT?

The person who discovered PLUT is Jakub Kroustek. This is a program that belongs to the Dharma ransomware family. Software of this type is used to encrypt data, to block access to it unless a ransom is paid. In other words, ransomware victims are forced to purchase a decryption tool/key. PLUT adds the ".PLUT" extension to every encrypted file, for example, it renames "1.jpg" to "1.jpg.id-1E857D00.[adolfhackler@tutanota.com].PLUT" and so on (it adds developer's email and victim's ID too). Ransom note can be found in a file named "RETURN FILES.txt", PLUT also displays one in a pop-up window.

The text file contains a couple of email addresses (adolfhackler@tutanota.com and adolfhackler@cock.li), these are the emails that supposed to be used to contact cyber criminals who developed PLUT. The note in a pop-up window says that PLUT ransomware encrypts data using RSA-1024 algorithm and that victims have 7 days to do it. After that decryption keys might be overwritten and encrypted data will be lost permanently. The ransom note informs victims that they should contact cyber criminals via one of the emails and to provide the ID that is appointed to them (each victims gets a unique ID). Once contacted, they will send instructions on how to make a payment (provide a Bitcoin wallet's address). PLUTs developers promise to send the decryption tool and key as soon as they receive the money. It is mentioned that any attempts to decrypt files using some other tool might increase the price of a decryption. Unfortunately, most ransomware developers use cryptography algorithms (symmetric or asymmetric), they cause strong encryptions that can be decrypted using tools/keys that only they have. Another problem is that most cyber criminals cannot be trusted, even if they have the right decryption tools. Typically, they urge victims to pay for them and, once they are paid, they disappear (do not send the decryption tools/keys). To avoid becoming victim of a scam, we recommend to restore all files from a data backup.

There are plenty malicious programs of this type on the Internet, SYSTEM FAILURE, DrWeb and Bufas are just a few examples. Most of them are very similar, they are used to encrypt data and keep it locked until cyber criminals are paid. Main differences usually are the ransom size (price of the decryption tool/key) and the cryptography algorithm which ransomware uses to encrypt data. Unfortunately, most encryptions without interference of particular ransomware's developers are impossible, unless ransomware is not fully developed, has some bugs, flaws etc. To prevent data and/or financial loss, we recommend to create data backups regularly and store them on remote server or unplugged/disconnected storage device.

How did ransomware infect my computer?

Ransomware-type programs and other high-risk computer infections usually are distributed though software 'cracking' tools, spam campaigns, trojans, fake software updaters and various untrustworthy software download sources. People use the aforementioned 'cracking' tools when they want to avoid paying for software activations. However, cyber criminals often employ them to proliferate malware too. Simply said, these tools often download and install malicious programs instead of bypassing paid activations. Spam campaigns can be used to spread malicious programs through files that are attached to emails that cyber criminals send to people. They send files such as Microsoft Office or PDF documents, archives like ZIP, RAR, executables (.exe and other similar files), JavaScript files and so on. Their main goal is to trick people into opening them which results in downloads and installations of various malicious software. Trojans are infections that, if installed, proliferate other infections (or cause other problems). Another way to spread viruses is by using untrustworthy software download sources. For example, Peer-to-Peer networks (like eMule, torrent clients and so on), freeware download, file hosting websites, or various unofficial pages. By using these sources people risk to download and install malware instead of the expected software. Cyber criminals successfully trick people into that by disguising malicious files as legitimate. Fake software updaters, if used, often infect systems by exploiting bugs, flaws of installed (and outdated) software, or by downloading and installing malicious programs instead of updating, or fixing programs.

How to protect yourself from ransomware infections?

If it is obvious that a received email is irrelevant and it also contains some web link or attachment, then it is best to simply ignore it (keep its contents unopened). Third party downloaders, installers or other similar tools should not be used to download any software. The best way to do it is using official websites (and direct download links). Unofficial software updating tools cannot be trusted, all installed software must be updated using implemented tools or functions that are provided by official software developers. Software activations should not be done using various 'cracking' tools, many of the mare designed to cause computer infections. Besides, it is not legal to use such tools (bypass activations). If there is no reputable anti-virus or anti-spyware software installed, it should be done right away. It is important to have a tool of this type installed and to keep it enabled at all times. If your computer is already infected with PLUT, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
