Removing the Corporate Monitoring Tool malicious browser extension
Written by Tomas Meskauskas on
What kind of software is Corporate Monitoring Tool?
While investigating suspicious sites, we discovered a deceptive webpage promoting an installer containing "Corporate Monitoring Tool". The malicious extension could be used to alter the appearance/operation of browsers and to collect sensitive user data. This browser extension could infiltrate devices alongside other dubious and harmful software.
Corporate Monitoring Tool extension overview
When we ran a rogue installer on our test machine, it installed the "Corporate Monitoring Tool" extension on the Google Chrome browser. This browser extension was presented as a tool for monitoring browsing activities on corporate networks. It requested various permissions, including:
- Access the page debugger backend
- Read and change all your data on all websites
- Read and change your browsing history on all your signed-in devices
- Display notifications
- Manage your downloads
- Open downloaded files
- Identify and eject storage devices
- Manage your apps, extensions, and themes
- Communicate with cooperating native applications
The exact usage of Corporate Monitoring Tool is used is currently unknown. It could be utilized to modify the appearance/operation of browsers and potentially even visited websites.
Additionally, the extension could spam users with browser notifications. These ads can promote online scams (phishing, technical support, etc.), untrustworthy/dangerous software (browser hijackers, adware, PUAs, etc.), and malware (trojans, ransomware, etc.).
Corporate Monitoring Tool's abilities could extend to other software through its "communicate with cooperating native applications" permission.
Data-tracking functionalities are prevalent in malicious extensions, and Corporate Monitoring Tool is not an exception. It can access users' browsing histories on all linked devices and downloaded files (as well as open them, which could be a severe privacy threat). It is possible that this extension may also be able to gather auto-fills (e.g., personally identifiable details, contact info, usernames, etc.), stored passwords, and saved credit/debit card numbers.
To summarize, the presence of software like Corporate Monitoring Tool on devices may lead to system infections, serious privacy issues, financial losses, and identity theft.

Examples of malicious browser extensions
We have analyzed countless malicious extensions; Violent_shark, Bull Checker, MoaNesiotis, AI Tab Optimizer Plus, and PassengerPigeon are just some of our latest articles.
The harmful capabilities of this software can be varied, ranging from data tracking/stealing, causing chain infections, modifying browsers, producing redirects, displaying ads, and so on.
Regardless of how a piece of malicious software operates – its presence on a system threatens device safety and user privacy. Therefore, all threats must be eliminated immediately upon detection.
How did Corporate Monitoring Tool install on my computer?
We downloaded an installation setup containing Corporate Monitoring Tool from a deceptive webpage. Dubious sites are often used to promote such software, and they are typically accessed via redirects generated by pages that use rogue advertising networks, mistyped URLs, intrusive ads, spam browser notifications, and installed adware.
"Bundling" – packing regular program installers with unwanted/malicious additions – is another potential distribution technique. Pre-packed setups can be downloaded from freeware and free file-hosting websites, Peer-to-Peer sharing networks, and other suspicious sources.
The risk of allowing bundled content into the system is increased by rushing installation processes (e.g., ignoring terms, skipping steps and sections, using "Easy/Express" settings, etc.).
Additionally, this software may be proliferated by intrusive adverts. Some of these advertisements can be triggered (by being clicked) to execute scripts that perform sneaky downloads/installations.
How to avoid installation of unwanted software?
We highly recommend researching software before downloading or purchasing. Furthermore, all downloads must be made from official and verified channels. Installation must be approached with caution, e.g., by studying terms and options, using the "Custom/Advanced" settings, and opting out of all additional apps, extensions, tools, etc.
We advise vigilance when browsing since fraudulent and dangerous online content usually appears legitimate and harmless. For example, while intrusive ads may look innocuous – they redirect to unreliable and questionable sites (e.g., gambling, pornography, scam-promoting, etc.).
Should you keep encountering adverts/redirects of this kind, inspect the device and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with Corporate Monitoring Tool, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this rogue software.
