Security thefts usually use it to steal PII which is Personally Identifiable Information, login credentials as well as sensitive enterprise data. These are designed primarily to create records of whatever you type on the system or mobile keyboard.
Where a Keylogger is commonly used
- Law Enforcement Agencies such as Police, FBI, CIA and more: They with its help analyze incidents which involve computer use.
- Companies: To observe and have an eye on all the employees’ computer activities.
- You: They track down all the unauthorized activities on their devices.
- A child’s parents: They supervise the internet usage of their kids.
- School, Colleges and Universities: They can use it to monitor if a class is actually paying attention or not.
How did Keyloggers begin (A little history)
It can be seen from the early computer days. It was used by the government clandestine operations back in the 70s and 80s.
A very famous incident happened back in the 70s when a clever hardware keylogger was developed by the soviet spied. It targeted IBM Selectric typewriters in US Embassy and Consulate buildings in Moscow and St. Petersburg. As it got installed it detected the barely detectable changes in every regional magnetic field of the typewriter as the print head both rotated and moved to type every letter.
As keylogging forms seem, the creation and use of commercial keyloggers were seen growing to significant numbers in the 90s. From that till now many of these have been available for purchase with different targeting audiences and languages too.
It has targeted homes for fraud, industry, and modern state-sponsored keylogging which is quite a serious issue, in this the phishing expedition compromises on the low-level employee for functions and then finds out ways t work with the company or the organization.
Benefits and Drawbacks of using a Keylogger built-in Python
- Increased productivity.
- A clear understanding of performance.
- Fewer chances of data stealing.
- Good access to the credentials stored on a device.
- A tough deterrent against all the viruses and phishing.
- Protection against any liability.
- Able to damage business relationships, reputations and financial standing.
- The organization could breach major pieces of legislation like Data Protection or Sarbanes Oxley Acts.
- If you have not followed any secure coding best practices in your own keylogger then it can work against you as other hackers may create a 0-day exploit.
How the Python Keylogger infects you
It makes its way when you download an infected app or the .py script, as it gets installed it monitors the strokes on the OS keeping a check on all the paths each keystroke goes through. Like this, the software keylogger is able to have an eye and record.
Some more methods are below:
- Security thefts can get their hands on passwords and other information using the keyboard.
- Cybercriminals can figure out your PINs, account numbers, login information for financial gaming as well as online shopping accounts.
- They send you an email with the keylogger as an attachment and you open it.
How does the Python Keylogger work on PC, Android and Mac
Now, the main question which might come in your mind is how does this work? Well, the answer is simple; it depends upon its type. Both hardware and software keyloggers work differently due to their medium.
When we talk about workstation keyboards then they are simply plugged into the back of the system keeping all the connections out of sight but the hardware keylogger might come in module form which is installed within the keyboard all by itself. As you type it collected every stroke and saved it as text in a location of your choice, hidden of course.
Now, the one who installs this must return and remove the device physically to have access to the information gathered. Moreover, there are also wireless keylogger sniffers which are able to intercept and decrypt data packets that are transferred between the wireless keyboard and its receiver.
Coming to software keylogger then it has two files that are installed in the same directory:
- DLL (Dynamic Link Library) file which is used to record.
- Executable file which installs the DLL file and triggers it.
Each stroke is recorded by the keylogger program and the user types and uploads the information over the net to whoever installed the program. Thefts can design these and then use the keyboard APIs to another app, malicious script injection or memory injection.
How To Create a fully functional keylogger in Python (With Send Email Feature)
Creating a keylogger in Python is a simple process that requires you to process the following 6 modules and create the script around them:
- Keyboard – This module is important so you can capture the keystrokes
- Smtplib – This is to make the keylogger send an email
- DateTime – So you can have a time and date on the data
- MIME Multi Part and MIME Text – This helps send the communications to Google and Outlook email accounts.
Once you have the above modules installed, please download the source code from the below link and run this .py file on the victim’s device or phone. Now you will start receiving emails weekly or monthly on all their keystrokes.
To run the keylogger, follow the steps below:
Step 1: Open CMD or Terminal and change the directory to the location of the downloaded source code.
Step 2: Now make sure you have Python installed by typing py.
Step 3: Now type the below and replace (my-keylogger) with your script name.
C:\Users\Paul> python3 my-keylogger.py
Step 4: All done, now it is running silently in the background.
2 Types of Keyloggers you can make with Python
Python is a powerful programming language that allows you to create any program type you can imagine (with some limitations) in mind.
User Mode Level
It uses windows API in order to incept movements of the mouse and the keyboard. GetAsyncKeyState or GetKeyState API functions may also be captured but it depends upon the keylogger. These need the attacker to actively monitor every keypress.
Kernel Mode Level
This is quite a powerful and complex method that tends to work with higher privileges and are not easy to locate as well. It uses filter drivers which are able to intercept keystrokes. Moreover, they are also able to modify the internal windows system via Kernel.
There are few which can record data like capture anything which has been copied to the clipboard and take shots of the screen of the users or even of a single application.
How to Detect a Keylogger Hack (Common Symptoms and Signs)
Till now, a question might be roaming here and there in your mind “how do you know if you have a keylogger or not?”, especially when fighting them is quite hard and a challenge itself. If you end up having anyone then you might not have an easy time seeing them on your device
Without software assistance, these are not easy to detect. Much of the system resources are consumed by malware and PUAs (Potentially Unwanted Applications). Data traffic, power and processor use can skyrocket thus leading to an infection. These probably do not create problems that are noticeable such as glitches or slow processes.
It is not easy to detect software keyloggers plus cannot be removed even with anti-virus programs. Spyware has all the tricks to hide because it usually appears in the form of normal files or traffic and has the potential to install itself. Keylogger malware may be there in the OS at the keyboard API level, memory, or even deep at the Kernel level itself.
Coming to Hardware keyloggers then it is not possible to detect them without any physical inspection. There are also chances that it might be detected by the security software. But, if the manufacturer of the device has built-in a hardware keylogger then there are chances you might need a new device to get rid of it or physically replace the storage chip, HDD or SSD, ouch!
To detect a software-level keylogger you have to select a free or comprehensive total-security package such as AVG, Avast, or BitDefender and you would have to run a full scan of both the system and the devices.
If you are lucky enough to have a hardware-level keylogger then you might only have a USB drive or an external hard drive that carries malicious material on it. In such a case all you need to do is simply remove the device with the help of your hand. Internal hardware would need a device torn down to discover. Make sure to make research before buying the devices to see if the manufacturer has included anything suspicious or not.
However, in some ways you can protect your system, we have listed them for you:
- Install software updates.
- Use firewall.
- Get a password manager.
- Think to get additional security tools.
- Turn on two-step verification.
- Use a password manager like 1Password or LastPass.
- Change passwords.
