Redirecting Rogue Extensions
Written by Tomas Meskauskas on (updated)
What is Redirecting Rogue Extension?
The Internet is full of applications/browser extensions that modify web browser settings without consent. These potentially unwanted programs (PUPs) and add-ons are categorized as browser hijackers. In most cases, these so-called browser hijackers infiltrate systems without users' consent - developers proliferate them using intrusive advertising and "bundling" methods.
Immediately after infiltration, hijackers modify the Internet Explorer, Google Chrome, and Mozilla Firefox browser options by assigning them to a specific URL.
In most cases, browser hijackers change only the default search engine, homepage, and new tab URL options, however, some are also designed to append targets of browser shortcuts with a URL address or modify the target. As a result, users inadvertently visit various websites when they search via the URL bar or simply open a new browser tab/window.
These redirects significantly diminish the browsing experience. Most browser hijackers promote search engines (both legitimate [such as search.yahoo.com or bing.com] and fake [for example, srcbar.com, go.pajosh.com, and others]).
Settings are typically modified in one of two ways: 1) direct URL [e.g., search.yahoo.com], or; 2) browser redirect commands (e.g., "chrome-extension://gcddnkpnineojbpkngblgamaciopbama/newtab/index.html#newTab" [for Google Chrome], "moz-extension://1662cb0c-5d9b-4479-89f1-67642b47bd91/newtab/index.html" [for Mozilla Firefox]).
In any case, users end up visiting irrelevant/dubious sites. Furthermore, although these changes may seem insignificant, users are unable to revert them. Most browser hijackers reassign browser settings when attempts are made to change them. Therefore, as long as rogue apps are present, returning browsers to their previous state is impossible.
Another important issue is information tracking. Research shows that browser hijackers often record IP addresses, website URLs visited, pages viewed, search queries, keystrokes, and other information that often includes personal data.
The information is shared with third parties (potentially, cyber criminals) who misuse private information to generate revenue - behavior that might lead to serious privacy issues or even identity theft. For these reasons, all browser-hijacking applications must be uninstalled immediately and, unless the promoted sites are legitimate, never return to them.

There are dozens of browser-hijacking applications. The list of examples includes (but is not limited to) BabyNameReady, Search Manager, Normandoh, and Stream It Where. Almost all offer "useful functionality", however, these claims are merely attempts to give the impression of legitimacy.
The only purpose of all browser hijackers is to generate revenue for the developers. Rather than enabling any of the functions promised, these PUPs cause unwanted redirects and gather sensitive information.
How did Redirecting Rogue Extensions install on my computer?
Some browser hijackers have official download/promotion websites, however, in most cases, developers distribute them using intrusive advertisements and the "bundling" method. Intrusive ads redirect to malicious websites and execute scripts that stealthily download and install various rogue programs (in this case, browser hijackers).
"Bundling" on the other hand, is stealth installation of third party software with regular (typically free) apps. Developers hide "bundled" PUPs within various sections (in most cases "Custom/Advanced" settings) of the download/installation processes. Furthermore, many users are careless when browsing the Internet and downloading/installing software.
They click various "tempting" (yet suspicious) links/ads, rush download/installation processes, and skip steps. In doing so, they expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of potentially unwanted applications?
Poor knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution and, therefore, pay close attention when browsing the Internet and downloading/installing software. Intrusive ads often seem legitimate, but once clicked, redirect to gambling, adult dating, pornography, and other dubious websites.
Most are delivered by adware-type PUPs. If you encounter them, immediately remove all suspicious applications and browser plug-ins.
Furthermore, select "Custom/Advanced" settings and carefully analyze each step of the download/installation processes. Opt-out of all additionally-included programs and decline offers to download/install them. Having a legitimate anti-virus/anti-spyware suite installed and running is also paramount.
