.bitcore Virus virus remove

The .bitcore virus is a new Paradise ransomware sample that is currently set against target end users on a global scale. There is no information available about the hacking group behind it. It is believed to be a new iteration of the famous ransomware family. This is one of the reasons why we believe that the hackers are experienced.

Once the .bitcore virus has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with the .bitcore extension.

.bitcore Virus – Spread and Impact

A new security report indicates that a new Paradise ransomware which renames the virus with the .bitcore extension. Like previous strains of this family of threats several of the popular attack techniques can be used to spread it. Larger campaigns can even use several ones at once.

Typical of Paradise ransomware strains the .bitcore virus can be spread by social engineering techniques. The criminals do this by sending out email messages and hosting malware sites on similar domain names. The aim is to make the victims think that they are accessing a legitimate and safe site or message. The virus file will be either launched in some way (through a banner or by clicking on a link) or it will be linked in a button, text link or image.

The other popular strategy is to embed the necessary .bitcore virus infection code into different file carriers. Depending on the attack strategy used by the hackers the virus can be found by accessing the malware-infected app installers — they are usually modified setup bundles of popular software. The alternative is to prepare macro-infected documents that can be of all popular formats. The mechanism is to present a prompt to the users asking them to enable the built-in macros. The posted reason is that this is required in order to correctly show the contents of the files.

Larger .bitcore attack campaigns can also use other techniques, for example the uploading of the dangerous files to different file-sharing networks and social networks. This is done by using fake or hacked accounts and profiles — this can be done publicly or via private messaging options.

.bitcore Virus – What Does It Do?

At the moment there is no information regarding the identity of the hackers. We do not know if they are experienced or have merely customized the base ransomware code. Whatever the case the infections have still not infected devices as much as previous threats. Still it is very possible that future versions may include many more dangerous components.

An in-depth security analysis is not yet available at the time of writing this article. However it is very possible that the virus includes many of the typical components that are often displayed by such viruses.

Usually these viruses begin by harvesting sensitive data from the compromised hosts. It can be related to the computers (hardware information) or personal information. The extracted data is used to carry out further crimes and also processed by the other available modules. A typical malicious action is to create an unique ID for each compromised system. The harvested personal information can be used for other crimes such as identity theft and financial abuse.

Many of the ransomware that are part of Paradise malware family may perform dangerous system changes such as the following:

  • Boot Options Changes — The .bitcore virus can be installed in a way which is referred to as a persistent infection. It will be started every time the computer is booted and it can block access to the recovery boot options. This will make it very difficult to remove the existing infections.
  • Windows Registry Changes — The virus engine can access the Windows Registry and edit out existing values or create new entries. This action will lead to performance issues, data loss and unexpected errors.
  • Additional Malware Infection — The made .bitcore ransomware infections can be used to deploy other viruses onto the compromised machines. Popular options include cryptocurrency miners, Trojans and browser hijackers.
  • Data Removal — Some of the viruses can be programmed to identify and remove sensitive information an files. This can include backups, restore points, databases and etc.

At any time other components and actions can occur, depending on the instructions of the hackers and local machine conditions.

.bitcore Virus – The Encryption Phase

When every module has finished running the actual encryption phase will start. A strong cipher will be started which will process the target user fles. It is very likely that this action will be done by looking for files that are described in a hacker-generated list. Usually this include the following data:

archives, backups, databases, multimedia files, documents, restore points and etc.

The files which are processed will receive a special extension called .bitcore which wil help identify the. The victims will be unable to access their files and will see several files that are called -=###_INFO_you_FILE_###=-.txt — these are the so-called ransom notes. These files will contain blackmail contents that aims to manipulate the victims into paying the hackers a restore fee.
