Remove Robot Captcha (robotcaptcha.info) virus from Android, Chrome, Firefox, IE
Cybercrime isn’t necessarily about predatory software that wreaks havoc with the infected computers and other devices. Its manifestations can be subtle at times, as is the case with adware that injects ads here and there, displays popups or redirects one’s browser, thereby causing some irritation but never crossing the line. Activity of that sort is inherent to Robot Captcha, an infection that forwards victims’ web traffic to a tricky site off and on.
What is Robot Captcha virus?
Most computer users are already accustomed with the fact that applications, especially mobile ones, require permissions they don’t seem to need and sometimes do it in a covert way. This is a complex matter of reading the fine print, something people hardly ever do. The Robot Captcha virus is about the scourge of excessive privileges, to a big extent. Meanwhile, it’s also about browser hijacking and malicious advertising. By the way, this type of a fusion has been gaining traction in the cybercriminal circles lately. The fishy Robot Captcha service hosted at robotcaptcha.info might appear to be a commonplace site that performs the function of verifying that the visitor is a human rather than a bot. However, that’s only the tip of the iceberg. The main goal of said page is to capture and redistribute one’s web traffic, subsequently forwarding it to various online resources whose owners are willing to pay for the promotion.
When infected, a user gets trapped in a series of recurrent visits to the dodgy spot. The resulting URL additionally has a tail that identifies the campaign or sub-campaign within the shady affiliate framework, so it will most likely look like this: robotcaptcha.info/robot3/index.html and may be concatenated with an extra random-looking ID string. On a contaminated Android device, the site address may take a slightly different form and be prepended with a single character, for instance, a.robotcaptcha.info. The overall malvertising functionality doesn’t differ much on a PC versus mobile gadget.
The basic element of the hoax is a popup that says, “robotcaptcha.info wants to show notifications” and contains two buttons: “Allow” and “Block”. Common sense prompts to hit the latter option, but that’s cold comfort because the message will reappear in a second or so. The most reasonable thing is to simply exit the page, although the issue will continue to make itself felt because of one quirk of the malware. The underlying malicious browser extension, which had most likely infiltrated the system as part of some freeware bundle, will keep causing the redirects. It can replace the homepage, new tab or preferred search engine with the rogue value so that the victim repeatedly hits the noxious page titled “Click Allow”.
If the Robot Captcha virus plagues an Android smartphone or tablet, it’s a little bit harder to avoid the event of granting redundant permissions. That’s due to the screen size and web browser peculiarities of mobile devices. The above-mentioned popup is more evasive, and the “Allow” button might be closer to the icon for exiting the browser tab. Therefore, the victim runs the risk of accidentally providing the culprit with the privileges it’s asking for. What happens next is, the user’s default browser on the Android device will start being redirected from robotcaptcha.info to different affiliated sites, including gambling hubs, ecommerce pages and the like.
In other words, the permission opens Pandora’s box and triggers the active phase of the hijack, coercing the victim to keep closing the tabs or look for a fix. Of course, the repair option is the only right way to handle the predicament. Below is a set of instructions to get rid of the Robot Captcha malware on Windows or Android.
