The RarVault Ransomware is a file encrypting Trojan and may exhort its victims to pay a fee after it encodes their data. While malware experts have yet to associate the RarVault Ransomware with a known family that includes free decryption options, neither is paying any ransom commendable due to the risks of conducting financial transactions with threat administrators. Removing the RarVault Ransomware with your favored anti-malware solution and keeping routine backups are the ideal means of fortifying your PC against this threat.

A Trojan Guarding a Vault with Collected Belongings

Marketing, website infrastructure, and a ransom note formatting all are some of the lesser aspects of the threatening software industry through which malware experts gather extra information about the responsible con artists. These threat actors may put no effort into the aesthetics and infrastructure of their threat campaigns, or they may make substantial investments. The RarVault Ransomware falls in a middle ground, where more than the bare minimum is put forth, but with some blatant omissions.

The RarVault Ransomware uses infection methods such as misnamed e-mail attachments or brute force attacks against RDP accounts to compromise your PC. The RarVault Ransomware scans for files such as DOC documents, BMP images, or MP3 sounds and enciphers them with an algorithm malware experts are in the middle of identifying. The RarVault Ransomware also may move the now-unusable data to an RAR-compressed archive or its personal directory. Each hard drive receives an independent folder, and the RarVault Ransomware may target network-mapped drives or your removable devices. This last trait is an unusual deviation from the payloads of most Trojan families that share the same classification.

After completing the encoding attack, the RarVault Ransomware launches a pop-up HTML page that its threat actors designed with relatively extensive customization for its campaign. The enclosed instructions elaborate on the nature of the RarVault Ransomware's attacks and recommend paying Bitcoins (currently amounting to 250 USD) in exchange for a supposedly 'automated' file restoration decryption process.

Choosing Between Breaking a Data Vault or Stopping Extortionists from Using It

There is always a risk of the threat actor not providing the promised assistance when a victim pays a con artist out of the hope of buying a decryption solution. While malware experts always advise keeping a close guard over the infection routes that Trojans could use, such as e-mail spam, backups are a cost-efficient solution to the data-ransoming dilemma of threats like the RarVault Ransomware. The RarVault Ransomware's campaign currently is targeting Russian and English-speaking PC owners.

Another characteristic of the RarVault Ransomware campaign is its base of operations on the Web, the site the RarVault.myfreesites.net. Malware experts associate the base domain with a variety of con artist activities, including impersonations of Outlook login interfaces for collecting passwords. However, the lack of use of TOR-based site infrastructure, which provides anonymity services often preferred by con artists, raises the point of how experienced the RarVault Ransomware's administrators are in their 'business.'

Whether this Trojan is the product of youthful hands or older but careless adult programmers, you should remove the RarVault Ransomware from your computer with a dedicated anti-malware application. Readers should remember that the relative tedium of keeping your PC secure is, as always, less of a chore than salvaging all of your data once the RarVault Ransomware encrypts it.
