WinLog

WinLog is a basic keylogger whose source code was released on a public platform for free recently. Open-source threats like this one are considered to be extra damaging since they are likely to attract a lot of attention from cybercriminals who will undoubtedly enjoy the opportunity to use a free tool that can be tailored according to their needs – thanks to the release of the source code, knowledgeable threat actors can use it as a foundation for a more sophisticated keylogger easily.

The version of the WinLog utility that is available for download is a rather simple, but it can still bring about a lot of damage if it ends up being installed on an unsupervised and unprotected computer. Once the 'server' component is initialized on the targeted host, the threat actor can use the 'client' component to command the operation of the keylogger.

A Basic Keylogger Project can Record Keystrokes & Grab Screenshots

The keylogger does what its name suggests – it keeps track of all keystrokes entered by the user, and it also provides information about the title of the window in which the data was entered. This may enable the remote attacker to collect login credentials or monitor conversations. Furthermore, WinLog also can grab screenshots of the victim's currently active windows and transfer them to the attacker's server.

No samples of the WinLog keylogger have been detected in the wild yet, but it probably will not be long before threat actors attempt to weaponize this public utility and use it for evil purposes.
