.Adair – Distribution and Impact

Malware specialsts have discovered that a new Phobos variant has been detected bearing the .Adair extension. The full security analysis is not yet available however we assume that they will follow the typical behavior of previous samples. This means that the hacking group has made modifications to the base engine.

The hackers will probaly follow the most popular distribution techniques by orchestrating various phishing campaigns. They utilize both email messages and web sites that impersonate popular services and sites. They are commonly hosted on similar sounding domain names, have stolen or fake contents and in many cases can be secured with self-signed certificates.

The other popular strategy is to create malware files which will lead to the .Adair virus installation. Popular types are the following:

  • Documents — The hackers can create malware documents across all popular file formats. This includes text files, spreadsheets, databases and presentations. When they are opened by the criminals a prompt will appear asking the victims to enable the built-in content. This will lead to the virus installation.
  • Setup Bundles — The criminals can create dangerous app installers of popular software. When they are run the virus will be installed alongside the program.
  • Web Browser Hijackers — These are dangerous plugins made compatible with the most popular web browsers. The hackers typically post them on hthe relevant repositories with hacked or fake credentials. To manipulate the victims into installing them the hackers can post fake user reviews and provide long lists of feature additions and extras.

The malware files and hyperlinks can be easily distributed over social networks and file-sharing networks. This includes the popular option BitTorrent. Files can also be sent over or linked in social networks with fake or hacked accounts.

As soon as the .Adair Phobos virus is launched on a given host it will start a series of malware modules which will be run according to the local conditions or to the specific hacker instructions. The list of affected modules can vary from machine to machine. A common component is the initial datta acquisition one which can be used to expose the identtiy of the victims and to create an ID for each virus-infected computer. This information can then be used to find out if there are any security software installed on a given host. This can work against products across a wide range of categories: anti-virus programs, firewalls, intrusion detection systems and etc.

When the security programs have been disabled the virus can edit out important settings including the boot options. This will manipulate the system so that the threat will be run every time the computer is started and also disable access to the recovery options. This module can also locate and delete sensitive files that may include backups and restore points making it very hard to recover the infected machines. If the malware is advanced enough it will also commit changes to the Windows Registry — the creation of new values and the manipulation of already existing ones. This can lead to system-wide issues like performance problems, errors, data loss and reconfiguration of the user preferences.

In the end the ransomware process will be started — the engine will process user data according to a built-in list of target file type extensions, commonly include the following: archives, databases, documents, multimedia files, backups and etc. The virus-specific .Adair extesnion will be applied to them automatically when the process has completed running. An associated ransomware note and/or lockscreen will be shown to the visitors.
