Our research team found the AcerPalmatum extension in an installer hosted on a deceptive page during a routine investigation of dubious websites.
AcerPalmatum targets Google Chrome and Microsoft Edge browsers. This malicious software can manage browsers' apps, extensions, themes, and other content/settings. Hence, AcerPalmatum is capable of altering browsers' behavior and appearance. The manipulation can be varied, as can the potential threats. Additionally, this extension may exploit browsers' vulnerabilities – thus opening an avenue to further the infection.
AcerPalmatum utilizes the "Managed by your organization" Chrome and Edge browser feature to gain additional functionality and ensure persistence.
Another worrisome function of this extension is reading browsing histories and collecting browser data. Targeted information may include: URLs visited, webpages viewed, search queries typed, Internet cookies, account log-in credentials, personally identifiable details, credit card numbers, and so on.

Unwanted browser extensions are often presented as existing software or disguised as common legitimate-looking tools. Users can also be lured into downloading/installing the software by promises of various "handy" functionalities, which are rarely operational. Instead of working as advertised, these extensions can function as adware, browser hijackers, or have other harmful functions.
How did AcerPalmatum install on my computer?
We obtained an installation setup containing AcerPalmatum from a deceptive webpage. Most visitors to unwanted/malicious software endorsing pages enter them via redirects caused by websites using rogue advertising networks, mistyped URLs, intrusive ads, spam browser notifications, or installed adware.
Ordinary program installers can also be bundled with harmful additions. The danger of unintentionally allowing bundled content into the system is increased by downloading from untrustworthy sources (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.) and compounded by treating installations with negligence (e.g., ignoring terms, using "Easy/Express" settings, etc.).
Intrusive advertisements spread this software as well. Once clicked on, some of the adverts can execute scripts to perform stealthy downloads/installations.
How to avoid installation of unwanted software?
It is crucial to be cautious while browsing since fake and malicious online content usually appears legitimate and innocuous. For example, intrusive adverts may look harmless yet redirect to highly questionable sites (e.g., scam-promoting, gambling, pornography, adult dating, etc.).
Another recommendation is to research software and download it only from official/verified channels. Installation processes must be treated with care, e.g., by reading terms, studying available options, using the "Custom" or "Advanced" settings, and opting out of all supplementary apps, extensions, tools, features, and so forth.
If your computer is already infected with AcerPalmatum, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this rogue software.
