.yoba Virus – Detailed Description
The .yoba virus as a new and dangerous ransomware threat has been detected in an ongoing attack campaign set against users globally. It is very possible that the most popular infection tactics will be utilized. A common tactic is the sending out of phishing email messages that will impersonate well-known services and companies — the recipients will notice the usual contents and may also click on the built-in links that will lead to the virus infection. A similar technique is the creation of numerous hacker-constructed sites — they will be hosted on similar sounding domain names and will include the stolen content in order to manipulate the users into interacting with it.
The .yoba virus infection as a malicious threat can be found within different types of file carriers such as the following:
- Malicious Documents — The dangerous macros code that will lead to the infection can be added to all popular file formats used by documents: presentations, text files, spreadsheets and databases.
- Bundle Installers — The hackers can create malicious setup bundles of popular applications. They usually target applications which are often downloaded and installed by end users: creativity suites, productivity tools, system utilities and etc. These installers are typically made by taking the original files from their official sources and modifying them to include the virus contents.
- Browser Hijackers — The criminals can create browser hijackers which are dangerous extensions made compatible with most popular web browsers. They are malicious in nature and are often uploaded to their relevant repositories with fake user reviews and developer credentials. This is done in order to persuade the victims into installing them.
The .yoba virus will probably run a premade sequence of malicious modules which will be governed according to the local system conditions or the hacker instructions. This usually begins with a module to conduct data harvesting — information regarding the users and their identity, as well as a full machine profile. This can be used to conduct various crimes such as financial abuse, identity theft and etc.
Various system changes can take place, some of the popular ones include the following steps:
- Boot Options Changes — The .yoba virus can be set as a persistent threat thus making it very hard to remove. This is possible by
- Windows Registry Changes — If any modifications are done to the Windows Registry or new ones are made the victims will experience serious performance issues, the inability to run certain functions or unexpected errors.
- Other Malware Deployment — The .yoba virus can be used as a conduit for other malware such as Trojans and cryptocurrency miners.
When all of these modules have finished running the actual file encryption will take place. By following the example of other well-known viruses a list of target file type extensions will be processed. Most of them include the following:
archives, documents, backups, multimedia files, databases and etc.
The victim files will be renamed with the .yoba extension. The associated ransomware note is created in a file called !=How_recovery_files=!.txt.
.yoba Virus – What Does It Do?
The .yoba Virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.
You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.
The .yoba Virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
