PsittacosaurusMongoliensis is a malicious browser extension discovered by our researchers during a routine investigation of dubious websites. It is worth mentioning that the type of installation setup used to promote this extension might also be bundled with adware, browser hijackers, PUAs, and other software.
PsittacosaurusMongoliensis overview
PsittacosaurusMongoliensis targets Google Chrome and Microsoft Edge browsers. It can modify these browsers' appearance and operation through its permissions to manage their applications, extensions, themes, and other settings/content. This extension could exploit browsers' vulnerabilities, thus opening an avenue for further infection.
Additionally, PsittacosaurusMongoliensis uses the "Managed by your organization" feature possessed by both Chrome and Edge. This feature is utilized for extra functionality and as a persistence-ensuring measure that complicates the malicious software's removal.
PsittacosaurusMongoliensis also has data-tracking abilities. Information of interest may include: browsing and search engine histories, Internet cookies, stored usernames/passwords, personally identifiable details, saved credit card numbers, and so forth. This vulnerable data can then be sold to third-parties or otherwise abused for profit.
It is pertinent to mention that malicious software developers often update or improve upon their creations. Therefore, potential future variants of this browser extension could boast additional capabilities or features.
To summarize, the presence of software like PsittacosaurusMongoliensis on devices may result in system infections, serious privacy issues, financial losses, and identity theft.

Rogue extensions can operate in a variety of ways, but the most common types are adware and browser hijackers. This software may be presented as legitimate and ordinary. It can also offer a broad range of "advantageous" functionalities, which are usually nonoperational.
However, it must be stressed that functional features do not serve as irrefutable proof of a software's legitimacy or safety.
How did PsittacosaurusMongoliensis install on my computer?
We acquired an installation setup containing PsittacosaurusMongoliensis from a dubious webpage. Users primarily enter such deceptive pages via redirects caused by sites employing rogue advertising networks, spam browser notifications, intrusive ads, misspelled URLs, or installed adware.
Another widely used distribution method is "bundling", wherein unwanted/malicious content is packed into installers of ordinary programs.
Download from untrustworthy sources (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.) and rushed installation processes (e.g., skipped steps, used "Easy/Express" settings, etc.) – increase the threat of unintentionally permitting access for bundled content into systems.
This type of software is also spread by intrusive adverts. Some of the advertisements can be triggered (i.e., by being clicked) to execute scripts that perform downloads/installations without user consent.
How to avoid installation of unwanted software?
It is important to always research software before downloading or purchasing it. We recommend downloading only from official and verified channels. When installing, it is essential to read terms, study possible options, use the "Custom" or "Advanced" settings, and opt out of all additional apps, extensions, features, and so on.
We advise caution while browsing since fraudulent and dangerous online content typically appears legitimate and harmless. An example of this would be intrusive ads, which may look ordinary/innocuous yet redirect to highly questionable sites (e.g., scam-promoting, gambling, pornography, adult dating, etc.).
If you keep encountering advertisements/redirects of this kind, inspect the system and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with PsittacosaurusMongoliensis, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this rogue software.
