.Wallet file virus: decrypt and remove Dharma ransomware

Over the past few weeks, numerous computer users have been reporting ransomware attacks where files are encrypted and appended with the .wallet extension.

The concatenation of certain strings to filenames is one of the most explicit symptoms of a crypto ransomware compromise. This tactic is used to flag data entries that the troublemaking software holds hostage. Although this is an annoying encounter, it’s merely a concomitant effect. The inaccessibility of one’s personal information poses a much more serious predicament. Nonetheless, these extensions are like fingerprints and can shed light on the specific ransomware sample a user is confronted with. By knowing the strain, it may be possible to find a data restoration workaround. The .wallet extension, for instance, denotes the so-called Dharma ransomware family. Having encoded a victim’s files, this offending code variant adds the .[email_address].wallet string to each one. For instance, a document named Manual.pdf will assume a shape like Manual.pdf.[[email protected]].wallet.

There are several other extensions in Dharma’s arsenal, including .zzzzz and .dharma proper. The .wallet suffix, however, is the most widespread one at this point. The list of email addresses prepended to this extension is fairly broad as well. It includes [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], and [email protected] The explanation of this is simple: there are multiple concurrent campaigns of Dharma ransomware distribution. Therefore, different cybercriminal groups indicate their contact details right in the crooked filenames. Keep in mind that no matter how illegal this business model is, it poses a huge darknet economy with its own affiliates, merchants, intermediaries and other interested parties.

The payload of the .wallet file virus mostly camouflages itself as an eye-catching email attachment, such as an invoice, job offer, banking fraud alert or ISP complaint. In other words, the fraudsters try to social-engineer users into opening the rogue email attachments. As soon as a targeted person opens one of these attached documents, the built-in JavaScript or VBA script instantly sets off the infection chain. Then, the ransomware determines what is to be encrypted on the computer’s hard disk and network shares. To this end, it scans all of these directories for popular formats of data.

The email address included in the affixed file attachments isn’t the only way to find out how to reach the adversary. The .wallet ransomware reiterates this information in the Readme.txt ransom notes, which are implanted into every folder with encrypted data. A copy will appear on the desktop as well. These notes with the decryption walkthrough are rather concise, only telling the victim that they got attacked and providing the email address to contact the hackers. Despite the fact that users can negotiate the size of the ransom, it normally won’t be lower than 1 Bitcoin. Instead of paying up and supporting the online extortion frenzy, first try the methods highlighted below.
