.online24files@airmail.cc Virus (Scarab Ransomware) – Distribution Techniques

The newest release belonging to the Scarab ransomware family has been identified in the .online24files@airmail.cc virus variant. The report indicates that the attack campaign is limited in scope, at the moment the collected samples are very few in number which doesn’t give out the main method of infection.

We suspect that the hackers behind the .online24files@airmail.cc virus are going to utilize the most popular distribution tactics. One of the most popular methods is to send out phishing SPAM messages that include various social engineering tactics that manipulate the users into thinking that that they have received a legitimate notification from a service they use or a well-known company. The message contents may contain links to the virus download posing as updates or new software offers. In some cases the files can also be directly attached to the emails.

A similar strategy is to construct phishing web sites that pose as download portals or software pages. Whenever the users access them they may think that they are visiting a safe place.

Many of the Scarab ransomware strains may also be integrated in infected payloads, two of the most popular types are the following:

  • Setup Files — The criminals can embed the virus infection code in popular application installers. Usually targets are system utilities, office suites, productivity applications and even games. Whenever they are installed from the infected source the ransomware will be deployed to the victim machine.
  • Malicious Documents — A similar strategy is employed with documents across all popular types: rich text documents, presentations, spreadsheets and databases. Whenever they are opened by the victims a prompt will appear asking them to enable the built-in scripts. This will trigger a macro function that will download the virus threat from a remote server and execute it on the local computer.

To further spread them to a larger audience both the stand-alone virus files and the infected payloads can be spread via file-sharing networks such as BitTorrent. The trackers used with this P2P technology distribute both legitimate and pirate content and as such they are very convenient for spreading the virus to a lot of people at the same time.

Larger infections can be done by using malicious web browser extensions which are made by criminals with code inside that downloads the ransomware. They are made compatible with all popular web browsers and uploaded to their relevant repositories with fake user reviews and developer credentials. The descriptions used by them will promise feature additions or performance optimizations. As soon as they are installed the virus download action will be started.

.online24files@airmail.cc Virus (Scarab Ransomware) – Detailed Analysis

The online24files@airmail.cc Virus as part of the Scarab ransomware threat follows the same behavior pattern as previous versions. This implies that at the onset of infection the main infection engine will copy itself to system folders in order to hide itself from any anti-virus software that may be installed. If a security bypass feature is included the engine will scan the memory and hard drive contents for such applications. Such actions do not only affect anti-virus companies, but also firewalls, debug environments and virtual machine host.

Further modifications to the system may include any of the following:

  • Windows Registry Modifications — The .online24files@airmail.cc virus may proceed with the modification of Windows Registry strings. This can be applied both to third-party installed software and the operating system as a whole. The direct effects upon the victim users are that certain functions or features may become inaccessible. Modifications to core values might also lead to serious performance issues with the system and overall stability.
  • System Data Removal — To make recovery more difficult the ransomware may also delete data such as System Restore Points, Backups and Shadow Volume Copies. This will make recovery very difficult unless a combination of a restore and anti-spyware software is used.
  • Additional Malware Delivery — Many Scarab ransomware variants such as the online24files@airmail.cc Virus may also be instructed into delivering other infections to the compromised machines. This can include Trojans, ransomware, cryptocurrency miners and etc.

Like other samples associated with the Scarab ransomware family this particular virus may also be modified to include other modules and actions. Remember that the infection behavior can shift between the campaigns.

In the case of a Trojan co-infection the hackers behind the campaigns will also be able to hijack user data (before the encryption has started) and also spy on the victims in real-time.

.online24files@airmail.cc Virus (Scarab Ransomware) – Encryption Process

When all prerequisite commands have completed the encryption process will be started. It will search for sensitive user data according to a built-in list of target file type extensions. An example one is the following:

  • Archives
  • Backups
  • Databases
  • Images
  • Videos
  • Music

All victim files will be renamed with the .online24files@airmail.cc extension which contains the email address used by the operators. The associated ransomware is created in a file called HOW TO RECOVER ENCRYPTED FILES-online24files@airmail.cc.TXT.
