As one of the newest representatives of the Trojan Horse malware category, Win32:KadrBot could be programmed to perform quite harmful and malicious targeted attacks. For instance, the hackers who have control over it may try to program it to secretly keep tabs on your online and offline activities and copy your passwords, banking data and online login credentials so that the hackers could get their hands on them.
