Definition[]
SubSeven (or Sub7) is the name of a popular backdoor program. It is mainly used for causing mischief, such as hiding the computer cursor, changing system settings or loading pornographic websites. However, it can also be used for more serious criminal applications, such as stealing credit card details with a keystroke logger.
Overview[]
Sub7 is usually stopped by antivirus software and a firewall, and with popular operating systems providing these features built in, it may become less of a computer security problem. However, if the executable is compressed, like being placed inside a .zip archive, some older antivirus software may not be able to detect it. Most modern antivirus applications have support to look inside archives, so this problem is now less critical than before.
