What is the Sigonews redirect/popup virus?

The duality of the Sigonews service becomes evident once you look slightly further than the information showcased on its website. On the one hand, it seems to be a run-of-the-mill “daily brand story” resource keeping the visitors tuned for news from well-known companies representing various industries, including consumer electronics, automotive, and entertainment. On the other, a stream of negative feedback about Sigonews has been recently heating up discussions that question its legitimacy and the innocuous motivations of its authors. The dark facet is all about numerous instances of browser interference resulting in redirects to Sigonews.com website. This tampering mainly occurs on Android smartphones and tablets, but it can affect PCs alike. The adverse activity stems from a cross-browser infection that reorganizes a victim’s web surfing preferences without asking for permission.

The infected Android and PC users keep visiting Sigonews.com in a loop of browser redirects

At first sight, an attack like this doesn’t appear to make a whole lot of sense. It’s hard to fathom the incentives that may lure someone into rerouting people’s Internet traffic to a harmless site.

However, the catch is hiding beneath the tip of the iceberg. Every time the redirect takes place, the navigation path encompasses a number of URLs in transit. These are domains operated by ad networks. They aren’t conspicuously resolved along the way, with the status bar at the bottom of the browser window showing these hits momentarily. Although Sigonews.com is the resulting page the users ultimately arrive at, it may not even be affiliated with the cybercriminals who are running this dirty campaign. The pivot of their foul play is a series of advertising networks visited as part of the divert hoax. Incidentally, redirects to several more landing pages may co-occur with the Sigonews issue. These include Techofires.com and Itfactly.com. All of them feature a very similar design and clearly hail from the same development source. Again, the destination sites are simply used for a distraction maneuver. Behind the red herring, there is a nasty traffic monetization hoax zeroing in on computers and Android devices.

This attack won’t take place unless the user unknowingly does something that triggers the infection chain. It can be a headlong acceptance of installation terms allegedly related to one benign application but turning out to be a one-shot consent to allow a bundle of programs to infiltrate a device. The potentially unwanted app constituting this package will instantly add a new browser extension that will, in turn, replace the victim’s default Internet settings with a rogue URL. Another scenario involves a hasty mouse click on an “Allow” button within a popup dialog that says some website wants to show notifications. This action might authorize a malicious script to invoke browser redirects to Sigonews.com further on. No matter which one of the above techniques is the case, the upshot is invariable: the affected web browser will be forwarded to the unwanted page under scrutiny off and on. It takes a specific virus removal procedure to stop this from happening. Keep reading to find out what cleaning steps will thoroughly eradicate the offending code.
