PBot Adware – How Does It Install Itself
During April 2018, researchers at Kaspersky labs have detected over 50 thousand attempts to install this adware on computers running Kespersky products. The adware has increased and this number is now significantly more than In spring 2018. This distribution of PythonBot is mainly concentrated in Russia and the adware is spread via what researchers refer to as “partner sites”. These types of sites have scripts embedded in the website code which aim to redirect users to web links that are third-party via a web browser redirect. This activity occurs in the following chain of activities:
- The user visits a corrupted site.
- When the user simply clicks with his mouse anywhere on the site, a new pop-up is displayed and it redirects to a web link, which is the download page of PythonBot adware.
- The download page automatically triggers and runs the adware after which the victim is already affected by a downloaded HTA type of file (Update.hta).
PBot Adware – More Information and Activity
PBot has come out in various different versions, which exist out there. And the latest update of the malware may include the usage of various different types of modules to change different settings on both the web browser of victimized computers and also make changes to Windows itself.
For starters, the newer variants of PythonBot, the Update.hta file, downloads and executes an original NSIS installer. This installer drops the following files on the victim’s computer:
- ml.py
- lauchall.py
- brplugin.py
- app.py
The file brplugin.py aims to interact with the web browser processes of the affected computers,for example chrome.exe or firefox.exe, etc. The app.py is a python file which is responsible for the malware to self-update by connecting it to the control and update server to perform a silent updating operation without the user even noticing it.
The ml.py file is the one file that is responsible for interacting with Windows Command Prompt (cmd.exe). The .py file adds tasks in Windows Task Scheduler which aim to execute it in a specific time every day. Another tasks is also related with running a winreg library which is used to write the script to the auto-loader.
All of these result in a browser toolbar or browser extension being added to the affected computer’s web browser which is re-added and runs diferrent types of tracking technologies on the computers affected by it. These tracking technologies also include the usage of:
- Cookies.
- LSOs (Locally Shared Objects).
- Tags.
- Pixels.
- Geo-locators.
These technologies are used by the PBot adware with the main purpose to collect different information from users, such as:
- Online search history.
- Online clicks.
- Typed information.
- Ads the user has clicked on.
- Bookmarked websites and browsing history.
The PythonBot adware then uses this information with the main purpose of getting users to download and install various different types of advertisement-supported programs or to cause browser redirects to websites with the same topics the users are interested in. This strategy is also known as behavioral advertising and it is used with the main purpose to lure users into pay-per-click schemes or websites that mine for cryptocurrencies, all with the end goal being profit for the developers of the PBot adware. The advertisements which may be displayed by this program as a result of that are many:
- Pop-ups.
- Browser redirections.
- Online banners.
- Highlighted text ads.
What makes PBot indirectly dangerous to your computer however is that the adware may lead you to dangerous websites, which may install other adware programs, scam you out of your information and even infect your computer with malware.
