What is RanunculusAcris?
During an investigation into a malicious installer, we came across RanunculusAcris and its concerning behavior as a browser extension. These activities encompassed the enabling of the "Managed by your organization" feature in the Chrome browser, the collection of diverse data, and the management of specific components of the browser.
RanunculusAcris in detail
RanunculusAcris has the ability to both retrieve and modify data from all web pages visited by users. This may include login credentials (e.g., usernames and passwords), browsing history, personal details, etc. Such capabilities pose a potential risk, as this data could be misused or exploited for malicious purposes, potentially leading to privacy breaches and other issues.
Furthermore, RanunculusAcris can alter the appearance and functionality of the browser by managing applications, extensions, and themes. This could result in unwelcome modifications that disrupt your browsing experience or expose users to potentially harmful content.
Additionally, our inquiry uncovered that the distributor of RanunculusAcris, the installation package, contains other unwanted programs, such as the Chromstera web browser. It is also common for programs like RanunculusAcris to be bundled with undesired applications like adware and browser hijackers.
It is important to note that the installers distributing programs like RanunculusAcris might also hide more dangerous threats such as ransomware, Trojans, cryptocurrency miners, and other types of malware designed to steal information, lock files, use computer resources to mine cryptocurrency, or perform other malicious actions.
