Lavasoft Security Bulletin: April 2013
Keystroke logging , often referred to as keylogging or keyboard capturing , is the action of recording logging the keys struck on a keyboard , typically covertly, so that the person using the keyboard is unaware that their actions are being monitored. Numerous keylogging methods exist: they range from hardware and software-based approaches to acoustic analysis. In short it is to record every key you press on the keyboard.
I mean Seriously??? However there are case like this where the creator did face consequences cause it had the sole purpose of being nefarious. Even thought of having this piece of software on your system would give goosebumps to many. Now there are many tutorials on installing and using these , anyone who has ever installed a software on Windows can do it pretty easily. We would be discussing the internals of what goes into making a good keylogger. The Desktop icons are quite easy to handle since they are the ones that are explicitly put by the software, so as to ease the use of their software , in case of keylogger , it just chooses not to put them.
Task Manager hiding or rather obfuscation using obscure names of the likes of system processes. Hiding from task manager is achieved using some of the techniques applied by rootkits , however it's beyond the scope of this article.
It is not that the email will come out of nowhere Did you really think so ;. At the time of installation you need to enter your email credentials , obviously you would create a fake mail just for this purpose , if I were you. This the part where my senses start piquing , don't you suspect some dark business going in the background , however save it for the last part ' The Consequences And Remediation '.
It works the same way as any email client like Thunderbird or MS Outlook would work. Every email provider has SMTP S imple M ail T ransfer P rotocol server such as gmail or yahoo or yandex which runs on port or any other given in their settings. The software connects to their server using your credentials and then sends the keylog file alongwith a subject if it could be configured into the keylogger i. The receiver as specified in the options of your keylogger then checks the email on a web client a sophisticated way to refer to a web browser ; or email client software as mentioned above.
Just login to your gmail ,go to this link and allow above script to use your account. Image Courtesy : NoCookie. Here comes the tricky part , some may say that how can one destroy itself without leaving a trail of itself.
Now if you would have googled ' Boost your PC performance ' you would've seen one of the solution would be to ' Clear the Temporary Files '. These files are automatically deleted by the OS on reboot. I hope you got the catch. So one may ask what is it used for? A Windows temporary file is created under the following three circumstances : 1. Note : Microsoft recommends that you have approximately 2 megabytes MB of free disk space available for the creation of temporary files.
Now suppose I create a batch file that when run deletes a file. Now combining the knowledge of above two things we can make the self destruct mechanism. First when the keylogger gets the auto destruct command it creates a bat file or something similar that could be executed , whose contents tell the OS to delete the files of the keylogger.
After executing the bat file the main keylogger exits as you can't delete the files of a running software that are being used by the OS. The bat file in turn gets destructed on next boot. Of course this one of the simplest ways among a myriad of methods there can be some other mechanisms too , I don't know all that is to know. It is achieved by using the windows ' Startup Programs ' mechanism however only the non stealthy applications seem to be using this mechanism or by using registry key.
The following list of registry keys are accessed during system start in order of their use by the different windows components: . The software path mentioned in these keys are run during startup. So there is ample space for the malware to slip into one of these and remain persistent. You can check out the currently configured autorun softwares using ' Autoruns ' a windows sysinternals tool.
The keylogger produces an installer file with your options embedded into it. There are many installer makers to name a few popular ones :. Well as far as the consequences go it so a no brainer as to what happens if you give your mail credentials to someone even if you set up the mail just for the keylogger , still your mail may be used in phishing campaigns or for signing up for different online services.
If it has a cloud storage linked to it then it can be used to store ' looted ' info such as stolen credit card info and other stuff , just to name a few. There can be no assurance that the keylogger you downloaded wouldn't be doing stuff apart from what it intended to do. Stuff like bitcoin mining or DDoS. However if it's a legit stuff bought from a legit company then it may be trusted.

Keystroke Logging Keylogging for short is defined by Wikipedia as : Keystroke logging , often referred to as keylogging or keyboard capturing , is the action of recording logging the keys struck on a keyboard , typically covertly, so that the person using the keyboard is unaware that their actions are being monitored.
What it actually pertains In short it is to record every key you press on the keyboard. Let me start with some of the basic features of modern keyloggers : Invisibility Cloak As in Harry Potter ; : Not shown in Task Manager and in any menu entries and of course no desktop icon Email: Email the logs to a predefined email address on a set interval of time or a particular time of day Auto Destruct : Deletes any trace of itself , without the victim ever knowing it existed Screen Capture : Capture screenshots Clipboard Monitoring : Monitor clipboard for changes Record Running Applications Persistence Remote Installation Some paid versions do offer it Even thought of having this piece of software on your system would give goosebumps to many.
How is it done Invisibility Cloak The Desktop icons are quite easy to handle since they are the ones that are explicitly put by the software, so as to ease the use of their software , in case of keylogger , it just chooses not to put them.
