How to Remove from Your Web Browsers?

Watch out! A browser hijacker named Cassiopesa is thriving at an alarming rate recently. For some Internet users, this computer infection is already known for its bold intrusion and disruptive behavior which is as notorious as other famous scam websites like Dregol Search and It has been reported as a redirect virus and malware before, however, its rouge actions become more frequent and its influence has been extended. Nowadays cyber criminals are more sophisticated and shrewd: they focus on attacks on the weaknesses in the network, searching breach of security layer which could be an open invitation for them to hack a computer system. In spite of the fact that the problem of cyber security has been addressed for a long time and actually has got increasing attention from people these years, hackers have never stopped exploring and expanding the range of targets. Not only do the antivirus programs keep updating their database industriously in order to better fight against malware, but the outside malware and virus are also struggling to find new ways to enter computers and reach their ulterior goal. Since there is always someone downloads software or share files via Internet, there will always be the chance for cyber criminals to initiate assaults on computer users. The technology wipes off the borders between countries, but it turns out that meanwhile cyber attacks are on the increase and becoming more complex.

Many browser users are keen to download some additional add-ons to add more features and functionalities to their browsers. A browser add-on can be a theme that allows you to change the look and feel of the browser, a browser extension that blocks ads, or a tool that improves your YouTube experience. I have to admit that this is something I’d like to do too, but I must point out that there is one thing you need to pay particular attention to: browser add-ons are not always reliable. An add-on can sometimes be a source of malware, especially those that are from unauthorized channels. Unsuspecting users can easily be dazzled and deceived by some free program that boasts how good its performance is and they will download and install that program at once even without thinking. Perhaps they are not to blame: there are too many ways for a malware to get inside a computer. In the case of Cassiopesa, victims typically download it from a spam site or install it along with other fake software mistakenly. The pictures I attached below are some examples I collected on several different website. As far as I can see, there have been a lot of computer users are hassled by Cassiopesa since May and it seems this trend will continue in future.

     Some users, particularly the users who are familiar with Chrome, may feel strange and have question about this: Chromium is an open-source web browser project, which is used for creating and upgrading Google Chrome. Basically, it can be regarded as the trial version of Chrome for their program codes are similar. It runs faster and possesses more features than Chrome and updates much frequently but there are also many bugs on it. As a commonly recognized browser, how can it become the publisher of a headachy browser hijacker? First you should know that what role an open-source browser project plays and what its functions are, then you can understand why it can be utilized by malware. It is released to public under multiple free licenses, so its open source can be used by any developer without further confirm or permission by Chromium. There has already been some successful browser platforms take advantage of it and build their own browsers with new features based on the Chromium source code. Thus, it is reasonable when you see it is with a malware. Since it has a very good reputation and can be used openly, the cyber crooks, without exception, will make use of it to conceal their real intent.

Or there may be a second possibility: the victim in this case has downloaded a bogus program that is similar to Chrome by its appearance. Let’s say, when the victim intended to download the latest version of Chrome, but for some reason, he or she downloaded a fake one instead carelessly and installed it on the computer. Almost all malware can be inserted into the installation package and be installed with the main program, and that is one of the capacities of Cassiopesa. An overwhelming majority of PC users never care what the installation package contains and what EULA or Privacy Policy is about. They just blindly get through the whole installation process and run the program immediately without knowing they have install some unwanted software at the same time. The worse thing is that the victim will keep using the fake program day by day and take it as the genuine one. There could be lots of untrustworthy commercial contents on the web page when the victim uses the fake browser. As the victim considers the browser is reliable, he or she won’t doubt the reliability of those ads and click on them trustingly, which may cause more unexpected results. Until the compromised computer starts to behave unusually or there is significant change coming into user’s notice, the victim will realize the computer has been infected with malware. From the photo below, we can see the name of the publisher is Cromium, but you can’t find any information related to it if you make search of this word with Google. I guess this may be a careless omission by its real publisher or that is just the truth of it: using a similar name with a well-reputed browser to hoodwink inexperienced computer users.

     I once tried to use Cassiopesa Search to search for browser to see what would happen, and I found the search results it provides giving high priority to irrelevant sites that are advertising sites and bogus pages crafted by cyber criminals. Another thing that made me feel weird about it is that I got nothing when I was trying to search for information of Firefox.

     But when I entered “browser” onto its search box, the results related to Firefox came into my eyes. However, the official sites are inundated with advertising websites. Anyone who does not pay attention to the small yellow icon reminding it is an ad will definitely open the sponsored link to get their desired contents.

     As to my case, I entered the search term of browser because I wanted to download a new browser on my PC. However, the official sites of Chrome, IE and Firefox are under these misleading ads. What if I open one of these advertising websites? To dig out the truth, I click on a link given by (Such action can only be performed by specialists of computer security for it may cause any unexpected damage to your computer).

     It is a page providing a source for you to download Firefox, isn’t it looks like a professional site that can be trusted? There is even a certification mark of McAfee that is the largest dedicated security technology company in the world. This provides strong evidence that the download resource supported by this website is thoroughly-tested and secure. What is more, we can’t find any ads or redirect links to other website on this page. The website theme seems so simple and clean with no disturbing content that general users might not consider it as a malicious website. People usually believe that a malicious website is full of annoying ads that can’t be closed, a lot of deceptive web links and irrelevant download links. Surely, a website with a plenty of pointless links and dazzling ads is a spam site, but we should learn that even a nice clean page can be a questionable site. When I clicked on the download button in this page, my browser instantly blocked this download and gave prompt warning me that this program may contain a virus or spyware. It would be dreadful if my browser security settings didn’t work. I would have installed spyware or an unknown computer virus will invade into my computer system and even steal my sensitive data.

     If you don’t know much about computer and Internet or have not got familiar with web pages, software download or any other online activities, you will tend to believe such a false website with crafted camouflage for covering. Only when you have built up a lot of experience about Internet and software, will you develop a specific intuition to tell you what is harmless and what will be harmful to your device. In this example, you can actually find there is something unusual in this website if you look more closely at the Software Information. In general, the number of the version of a program is not named for date like year and month, even if that version is published this year, its version number will not be displayed as like “2015.xx”. If you have ever used Firefox before, you will know its version numbers are in consecutive order from 1. In 2012, the number turned to a double-digit and now its latest version is 40. If you have already know the history version of Firefox, you will learn that the Firefox free download on this website is a fake one since the real one will not be anything like that. What is more, if you see the official site of Firefox is listed among the search results, what makes you to download this browser from other download site that is strange to you? The lack of basic knowledge of Internet and being careless are two main reasons for many computer users have malware or virus on their computers. However, in more other cases, the victims totally had no idea about what are the problems of their computers. They can see lots of unwanted ads keep showing up on the screen and feel the running speed of the computer is much slower, but they can never figure out the reason.

     The picture above just two examples I selected to show you how they are installed with other freeware on the system. Most of users just simply click on “Next” or “Accept” and never pay attention to the content of each step. They just want to get the desirable program as quickly as possible without knowing what they are actually doing. Please keep in mind that such browser hijacker or other kinds of malware usually bundle with other free programs that are available for all Internet users. They can be downloaded or installed when you download or install the program you desire for simultaneously, so you should be careful when you intend to download or install any free application via Internet and make sure you are not installing additional programs on your computer during the installation process. Additionally, you are advised not to click on any pop-up ads or redirect links that you are not sure where you head to, or you may be brought to phishing websites that may cause you a great loss. Before you open the attachment of any email, you should check for its security. Even the email is sent by your friends or families, it could be the situation that the hackers has broken into their accounts and send you an infected file trying to get into your computers. And the most important thing is, make your PC work with a good antivirus or antimalware.
