Vosteran, a potentially unwanted web service enhancement, gets dissected in this entry in terms of technical nuances and dependable removal methods.
“Vosteran” is a Catalan word for the pronoun “your” in English. That’s semantics. In computer terms, it denotes an unwanted browser helper object which appeared on the underhand cyber stage a few weeks ago, so it’s relatively new. Also referred to as WSE_Vosteran or Vosteran New Tab, this app makes you forget about everything custom when it comes to web surfing. Having installed on to a PC, it deploys some browser preferences swapping in order to make the user end up on vosteran.com in a recurrent fashion. These isn’t really a redirect story because the URL for homepage, new tab page and default search gets to be sort of hard-coded in the respective configuration fields for Firefox, Chrome and Internet Explorer. So, whenever the victim opens one of the above browsers, triggers a new tab or intends to search for random information online, the wrong page appears instead of the right one. Essentially, this is a rather typical implementation of a traffic redistribution scheme, where the compromised users’ web browsers get exploited for someone else’s commercial aims while causing them a lot of frustration.
