.acute Files Virus – Distribution and Impact
The .acute files virus is a new release of the Phobos ransomware which is being spread against victims worldwide. It is very probable that the hackers behind it have customized the main engine by themselves in order to create this custom release. The alternative is for them is to pay other hackers to make the .acute derivative.
The infection data can be distributed using a variety of methods, the most popular of them are the following:
- Documents and Installers — The hackers can embed the necessary installation scripts via macros in documents and also in setup packages of programs.
- Scam Emails and Sites — This is one of the most widely used strategies that take advantage of the fact that most computer users can be easily deceived into thinking that they are accessing legitimate contents. The hackers coordinate email campaigns and can craft sites that are hosted on domains that sound legitimate and safe.
- Malicious Web Browser Extensions — A widely used mechanism for the creation of viruses is the inserting of the relevant code into plugins for the most popular web browsers. They are uploaded to the relevant repositories using fake or stolen developer credentials.
When the .acute files virus is delivered onto a given computer it will immediately start to execute its built-in behavior pattern. Common modules that are run are also part of previous Phobos ransomware strains. An example is information gathering module which can hijack data that can be used to identify both the users and their machines. This is particularly useful for generating unique signatures for every infected host. Furthermore the hard disk and memory scan can reveal if there are any security programs and services available on the computers. The security bypass module can be used to remove or block the execution of applications such as: anti-virus programs, firewalls, sandbox environments, virtual machine hosts.
Usually this is followed by system changes that include modifications to the boot options thereby starting the virus engine when the computer is powered on. In some cases this also disable access to certain recovery menus and options. If any changes are made to the Windows Registry then existing values can be modified or new ones specific to the virus can be added.
One of the most dangerous aspects of having an active .acute files virus infection is the fact that it can be used to deploy other threats including Trojans depending on local conditions or by a trigger made by the hackers. The actual file encryption will follow — target user data will be processed by a powerful cipher according to a built-in list of file type extensions. Like previous Phobos ransomware it will act against data such as the following: archives, backups, databases, multimedia files and etc. All processed files will receive the .acute extension and a ransomware note will be generated in order to blackmail the victims into paying the hackers.
