Blackshades is the name of a malicious trojan horse used by hackers to control computers remotely. The malware targets computers using Microsoft Windows -based operating systems. According to US officials, over 500,000 computer systems have been infected worldwide with the software. In 2014, the United States Federal Bureau of Investigation (FBI) arrested one hundred people who had Blackshades in their computer. Before the FBI crackdown, Blackshades was sold for US$40, and reportedly generated US$350,000 in sales.〔 == Functionality == Blackshades infects computer systems by downloading onto a victim's computer when the victim accesses a malicious webpage (sometimes downloading onto the victim's computer without the victim's knowledge, known as a drive-by download) or through external storage devices, such as USB flash drives. Blackshades also included tools that assisted hackers in maximizing the amount of computer systems infected, such as a tool that sends infected links that masquerade as an innocuous site to other potential victims via the victim's social networking service. Blackshades can reportedly be used remotely to access an infected computer without authorization. Blackshades allows hackers to perform many actions on an infected computer remotely without authorization, including the ability to:〔 * Access and modify files on the victim's computer. * Log keystrokes on the victim's computer. * Access to the webcam of the victim. * Include the victim's computer in a botnet, which allows the attacker to perform denial-of-service attacks with the victim's computer, and usually along with other infected computers. * Download and execute files on the victim's computer. * Use the victim's computer as a proxy server. Blackshades reportedly can be used by computer hackers with little experience or by script kiddies, hackers that use programs developed by others to attack computer systems.〔 Blackshades can also act as ransomware. Hackers using Blackshades can restrict access to the victim's computer and demand a ransom paid to the hacker in order for the restriction to be lifted.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Blackshades」の詳細全文を読む スポンサード リンク
