Distribution of .viiper Virus
The .viiper virus is a customized form of the Hidden Tear family of malware. As such the hackers behind it continue to use the same tactics as the original virus strain. The criminals depend mostly on email messages that feature a social engineering tactic which blackmails the targets into infecting themselves. Depending on the hacker campaign there may be different types of strategies involved. The first ones involves sending the .viiper virus strains directly as file attachments. The victims are lured into executing them via the message in the body.
Another option would be to insert hyperlinks in the messages which link to the .viiper virus hosted on download sites. The criminals behind the .viiper virus can also use infected documents as part of the scheme. This technique involves the modification of a range of document types (rich text files, databases, presentations or spreadsheets) with the .viiper virus malware instance. The infection is started as soon as the file is opened or the internal scripts (also known as macros) are run.
Computer criminals in the case of the Hidden Tear malware also utilize infected software installers to spread viruses. They rely on popular application which are downloaded from their official sources and then modified to include the .viiper virus. Victims will discover that often the hackers resort to popular free or trial software such as the Adobe Flash Player, Internet browsers, Adobe Photoshop and etc.
Browser hijackers are another major source of infections with the .viiper virus. They represent malicious addons for the most popular web browsers: Internet Explorer, Mozilla Firefox, Google Chrome, Opera and Safari. Once installed they not only infect the users with the malware, but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hihackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.

The security researchers that alerted of the .viiper virus strain note that it is a customized version of the infamous Hidden Tear malware family. This is one of the most well-known virus types as its source is open and widely available both on the general Internet and the specialist hacker forums. Anyone who has access to its code can make modifications to the engine and change important parameters such as the ransomware note, extension and any additional active features.
At the moment the discovered strain seems to be an initial version. It contains just a basic encryption engine, however it is posslble to spot an updated version in the near future. A newer version of the .viiper virus may include modules such as the following:
- Trojan Instances ‒ Computer hackers use such features to spy in real time the victim computers.
- Information Harvesting ‒ Advanced versions of the .viiper virus can be used to steal sensitive data from the infected machines prior to the encryption process.
- Additional Malware Infections ‒ Like other Hidden Tear strains the .viiper virus can be used to deliver multiple infections at once.
- Persistent Installation ‒ This is a deep infection tactic which actively prevents manual removal attempts from the user’s part. When such a threat is involved in a computer attack the only way to effectively remove is by using a quality anti-malware solution.

The typical cases include the most popular data: archives, spreadsheets, presentations, documents, configuration files, photos, music, vieos, databases and etc. All processed files receive the .viiper extension.
