Inor.BI is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information; email addresses; screenshots of actions carried out.
It sends the gathered information to a remote user by any available means: email, FTP, etc.
It reduces the security level of the computer:
it changes the security settings of Internet Explorer, decreasing its security level; it changes system permissions, decreasing the security level.
Inor.BI uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.
