What is ChromeLoader?
According to threat analysts (1, 2), ChromeLoader is malware designed to download and install malicious browser extensions on the victim’s computer. At the moment there are two versions of the ChromeLoader malware, the first is aimed at the Windows system, and the second at MacOS. It is already known that this malware is spreading through Twitter across the world. Criminals use QR codes to post malicious links that masquerade as links to videos and pirated software.
27 security vendors flagged ChromeLoader as malware:
During the analysis, the security researchers revealed that ChromeLoader is an ISO file that contains two components “_meta.txt” and “downloader.exe”. The first file is the encrypted PowerShell script and the second is its decryptor.
Upon execution, it creates a task called “ChromeTask” (may be different) and sets it up to run every ten minutes. Next, it downloads the malicious Google Chrome browser extension “archive.zip”. Some victims of the malware reported that due to the repeated execution of this task, their browser closed unexpectedly. Since it can help victims detect the presence of malware on the computer, it will likely be patched by the ChromeLoader authors in the future to prevent its detection.
As we said above, ChromeLoader downloads and installs malicious extensions, and to prevent users from removing them, it blocks access to the list of Google Chrome extensions (“chrome://extensions/”), redirecting users to general settings (“chrome: //settings”).
Since the main target of ChromeLoader is browsers, then this malware falls into the category of Browser hijackers. Browser hijackers are a kind of malicious software designed to change the web browser settings without the knowledge or permission of the computer user, and it usually redirects the affected system’s browser to some advertisement-related webpages. Browser hijackers can change the default search engine or homepage, initiate numerous popups, install multiple toolbars and malicious extensions, redirect user web searches and generate multiple pop-up advertisements.
And finally, ChromeLoader can be used to gather a wide variety of information, including:
- IP addresses;
- URLs visited;
- search queries/terms;
- clicks on links and ads;
- web-browser version information.
So, if you happen to encounter this malware or other such problem, then be quick and take effort to remove it ASAP. Follow the instructions below to remove ChromeLoader. Let us know how you managed by sending us your comments please.
