The above regexes are meant to hint at what can be done with smart regex scanning.

Here is an example of two regexes that would match the usernames and passwords from a wall of text: //Identify Password It’s like a mini language for scanning patterns and matching against the pattern that we have defined. It’s a good time to now make the acquaintance of regular expressions or regex. Result: a huge file with megabytes of text in which the good stuff, emails addresses and passwords, are hidden. Suppose this is an ambitious hacker who has managed to infect tens or hundreds thousands of laptops.

Let’s assume the hacker has been pulling the output from keyloggers using something like the code above. I’ve just ensured I will get the keystrokes only when the user is surfing within a browser, and only at the sites “Facebook” or “Gmail” login pages. You can learn more about this API at MSDN. The title of the window will be returned in the “buff” variable, and the keyboard scanning code called if it contains the word “Facebook” or “Gmail. GetForegroundWindow does the real heaving lifting. This code snippet will probe the active window every 100ms. If (line.Contains("Gmail")|| line.Contains("Facebook - Log In or Sign Up ")) Now you continually call this function to get the keyboard data you need: while (true) Summing up these two lines of code in one sentence: it determines whether a key is up or down at the time the function is called, and whether the key was pressed after a previous call to GetAsyncKeyState. You can read more about the GetAsyncKeyState API from MSDN: Public static extern int GetAsyncKeyState(Int32 i) To hook into the keyboard, all you have to do is use these two C# lines: Let’s just say malware in the wild is good at being resistant to removal even if you manage to detect it. I don’t want to go too far into the dark side.

I’m just showing you the bits of code that perform the desired action - it’s not the most elegant or best way to do it.įinally, I will not be showing you how to make the keylogger persistent so that it survives a reboot, or will I show how to make it avoid detection through using special coding techniques. Next, the examples below will not compile on their own. If you’re going to try some of this on your own in a business environment, make sure to get permission and perhaps work your tests in a separate VM. But first a few warnings to make our lawyers happy. However, the key logger function is fairly easy to code. There are hardware/fimware keyloggers, but they’re less common since they require physical access to the machine or directly tampering with the hardware. Andy has already written about how keyloggers are typically part of Remote Access Trojans or RATS, which also provide stealthy ways to get the logged keystrokes back to the attacker. Often the keylogger function is embedded in another piece of malware. Think of it as digital tap that captures every keystroke from the keyboard.

Keyloggers for IT PeopleĪ keylogger is a piece of a software or hardware that can intercepting and record the keystrokes of a compromised machine. I also like using C# in my coding examples since it can be read like a story even if one isn’t familiar with the syntax. Keep in mind that most real-world malware tools are coded in C/C++/Delphi in order to discard the dependency of. I won’t be getting too technical, so don’t get scared off.įor these informal “hacking 101 classes”, you’ll need coding knowledge - C# and Java - and some understanding of Windows. Once you understand how relatively simple it is to create undetectable malware, you’ll want to take a different approach to data security at your organization.

I’m an infosec specialist at Varonis and in my experience, you’ll be better at data security once you understand how the offense plays its game.Īnd that’s the reason I decided to start this series of posts on the details underlying malware and different hacking tool families. As Inside Out blog has been pointing out, you have to think like a hacker to stop one. Why Should an IT Person Learn These Dark Skills?įile that under “know your enemy”. On the other hand, I really believe that an IT security person should master some of the programming concepts that go into malware. “In just one hour, I’ll teach you the fundamentals of Ransomware and what you can do to protect and prepare for it.”
