Trojan.Kasidet is a threat meant to operate on the victim's machine silently to exfiltrate sensitive information, as well as download and execute files on the compromised computer. These capabilities make Trojan.Kasidet to be threatening exceptionally since its operators are free to deploy additional threats on the infected machine. When Trojan.Kasidet is deployed, it will replicate itself to several system directories to make the manual identification and removal of its files a difficult task. In addition to this, Trojan.Kasidet also will add a Windows Registry key to ensure that it will be launched as soon as Windows boots. After this, Trojan.Kasidet is capable of establishing a connection with several compromised Web servers, which are likely to be used as Command & Control (C&C) servers.

Some of the basic abilities that Trojan.Kasidet is known to possess are:

  • Download and execute remote files on the infected computer.
  • Establish HTTP connection with remote hosts.
  • Search for specific files on the computer and exfiltrate them via either FTP or HTTP protocol.
  • Serve as a keylogger.
  • Obtain information about the computer's hardware and software.

Needless to say, all threatening actions listed above are very harmful, and you must take all precautions to ensure that Trojan.Kasidet is not running on your PC. Naturally, the best protection against high-profile cyber-threats like this one is to use a reputable anti-virus software suite. In addition to this, it also is recommended to try to browse the Web as safely as possible by staying away from suspicious websites, dubious e-mails, and pages known to distribute pirated or illicit media and software.
