This week, we are continuing with:
Injector
This is the same as a Dropper
JavaScript
JavaScript is a scripting language that can run wherever there is a suitable script interpreter such as Web Browsers or Web Servers.
A web page with JavaScript runs within a web browser in much the same way as Java applets and does not have access to host machine resources.
An Active Server Page (ASP) or a Windows Scripting Host (WSH) script containing JavaScript is potentially hazardous since these environments allow scripts unrestricted access to machine resources (file system, registry, etc.) and application objects.
Key
The Windows Registry uses keys to store computer configuration settings. When a user installs a new program or the configuration settings are otherwise altered, the values of these keys change. If viruses modify these keys, they can do damage.
Key Logger
Key loggers are malicious programs that record the key strokes a user types on the PC. They will log every single keystroke in the hope that the user types in bank account details or credit card numbers, anything that could be used to defraud.
There are many different methods to capture the data typed on the keyboard, below are a few of the more popular methods:
Software Based Key Loggers
Software developed to work on the target computer and capture the keys typed on the keyboard, different types of Software Key Loggers range from malware type loggers to loggers sitting waiting in the system Bios.
Remote Based Key Loggers
These are Software Key Loggers residing on the user PC and transmit the data to a remote location.
The recorded strokes are recorded and sent to the remote location either by email, LAN connection, FTP or SMS.
Hardware Based Key Loggers
As it suggests, this is a piece of hardware attached to the PC to log all key strokes. This is simpler than the Software Key Loggers as it will not slow the PC down, but can be easily identified as a piece of hardware not installed by the user.
The Glossary will continue next week. In the meantime, should you have any questions, please feel free to contact us!
