Pluto ransomware removal instructions

What is Pluto?

Pluto is one of many ransomware-type viruses discovered by malware security researcher, Michael Gillespie. Following successful infiltration, Pluto encrypts most stored files and appends filenames with the ".pluto" extension (e.g., "sample.jpg" is renamed to "sample.jpg.pluto"). Once encryption is complete, Pluto generates a text file ("!!!READ_IT!!!.txt") that contains a ransom-demand message. Another variants of this ransomware use ".Neptune" and ".mecury" extensions for encrypted files.

The ransom-demand message is short and simply states that data is encrypted and can only be restored using a unique decryption tool. To receive the tool, victims must contact developers (cyber criminals) via one of the email addresses provided and attach their unique IDs. As a 'guarantee' that files can be decrypted, victims can attach a file (which does not contain any important information). This will then be restored and returned to the victim together with the payment instructions. Unfortunately, only cyber criminals can restore encrypted data. It is currently not known whether Pluto uses symmetric or asymmetric cryptography. In all cases, however, decryption requires a unique key generated individually for each victim. All keys are stored on a remote server controlled by cyber criminals. Therefore, to receive their keys (or a decryption tool with the key embedded within), each victim is encouraged to pay a ransom. The cost is not specified within the text file (all details are provided via email), however, in most cases, the size of ransom fluctuates between $500 and $1500 in Bitcoins or other cryptocurrency. Regardless of the cost, do not pay. Research shows that these people often ignore victims, once payments are submitted. Therefore, paying often gives no positive result and users are scammed. We strongly recommend that you ignore all requests to submit payments or pay any ransoms. Unfortunately, there are no tools capable of cracking Pluto encryption and restoring data free of charge. Therefore, the only solution is to restore everything from a backup.

Pluto is regular ransomware and thus shares many similarities with dozens of other viruses of this type including Frend, Cryptotes, Maoloa, and CryptoID - these are just some examples from many. As with Pluto, these malware infections also encrypt data and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Unfortunately, most are developed to encrypt data using algorithms such as RSA, AES, and others that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar), manual decryption without involvement of developers (contacting these people is not recommended) is impossible. To prevent permanent data loss, we strongly advise you to maintain regular data backups and store them on remote servers or unplugged storage devices. Locally stored backups are encrypted together with regular data.

How did ransomware infect my computer?

To proliferate ransomware-type viruses, cyber criminals typically use trojans, fake software update tools, cracks, third party software download sources, and spam email campaigns. Trojans are malicious applications that, once infiltrated, cause so-called "chain infections". Therefore, these apps infiltrate computers and continually inject them with other malware. Fake software updaters infect systems by misusing outdated software bugs/flaws or simply downloading and installing malware rather than the promised updates. Software cracks allow users to bypass software activation, however, this is a common way for cyber criminals to proliferate malware. Rather than activating paid software free of charge, users end up infecting their computers. Spam campaigns are used to proliferate malware via malicious attachments. Cyber criminals send deceptive emails that contain messages encouraging users to open attached links/files, however, this typically leads to high-risk computer infections. Unofficial download sources are often used to distribute malicious apps. Cyber criminals present them as legitimate software, thereby tricking users into downloading and installing malware manually. In most cases, lack of knowledge and careless behavior are the main reasons for computer infections.

Threat Summary:
NamePluto virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.
Distribution methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.

To eliminate Pluto virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, pay close attention during the download/update/installation processes and when browsing the internet. Download your programs from official sources only, using direct download links. Keep installed applications up-to-date. To achieve this, however, use only implemented functions or tools provided by the official developer. Furthermore, never use software cracking tools, since software piracy is considered a cyber crime and there is also high-risk of computer infection. Carefully analyze each email attachment received. Files that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. Reputable anti-virus/anti-spyware suites can detect and remove malware before it harms the system - therefore, have this software installed and running. If your computer is already infected with Pluto, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
