Finding relevant information on any subject is a piece of cake these days – all it takes is typing the query in a search engine of choice. Which search engine? It’s a matter of personal preferences, habits and perception of convenience. Sometimes, though, users need to see and compare data returned by different services to get the big picture, and that’s the catch that the authors of Search Pulse app are cashing in on. They boil their marketing down to the following perk: people can visit one page, select a search provider out of three available options there, and get the results on the same page without having to use each service separately.

Sounds nifty, but there is a major pitfall in the implementation of this whole idea. The Search Pulse applet penetrates into Mac computers uninvited and it forcibly gives the browsing settings an overhaul without asking for the admin’s consent about driving traffic to home.searchpulse.net. Normal software doesn’t act this way, which explains why lots of users flag this one as a PUP (potentially unwanted program) or even a virus.

Rather than go the route of an informed decision, the penetration of the Search Pulse virus into a Mac resembles a trespass bypassing the victim’s approval. The most likely technique is based on bundling, a software distribution practice that promotes a package of applications as an appendage to the one the user is aware of. In plain words, harmful entities may accompany benign programs during installation in such a way that the targeted person stays clueless about the stratagem until the culprit shows its fangs. This is exactly what happens in the Search Pulse intrusion scenario. Thankfully, it’s a no-brainer to avoid this infection vector – just choosing “Custom” in the install options will allow for exploring the bundle and deselecting the unwanted items. But, most Mac users go with the flow and never peek beyond the default setup, only to get infected and deal with the consequences.

When inside, the Search Pulse virus instantly modifies the browser configuration so that the traffic is repeatedly forwarded to home.searchpulse.net, or less often to search.searchpulse.net. In most cases, the pest replaces the admin’s homepage, search engine and new tab settings with the above value. As a result, Safari, Chrome and Firefox will be redirected to the rogue landing page over and over. The site itself has minimalist design. It contains a search bar with the search engine select dropdown next to it, allowing the visitor to choose from Google, Yahoo, and Bing. There’s additionally a current time widget at the top and an option at the bottom for setting a different background. The general impression from the service might be okay, but the very “peculiar” way Search Pulse spreads is a giveaway.

This threat has gained notoriety for its stubborn behavior. Normally, if a Mac user wants to change their browsing defaults, all it takes is going to the settings and selecting the preferred service from a list or typing in the correct URL. In the case of the Search Pulse virus, things are way more complicated than that. It configures the affected browser to resolve a rogue site once launched and also whenever the victim opens a new tab. Strangely enough, the unwanted setting isn’t searchpulse.net proper. Instead, it’s usually lkysearchds1122-a.akamaihd.net or similar-looking domain, with the address being followed by a long string of alphanumeric campaign IDs. The dodgy attributes constituting this site’s URL invoke a further redirect to search.searchpulse.net, and from there to Yahoo most of the time.

The above-mentioned persistence of this whole misconfiguration is all about the fact that the appropriate settings fields are grayed out and inactive, and therefore the victim cannot replace them with the right values easily. This is an outcome of a whole separate vector of Search Pulse’s tactic. It creates a new user profile in the host Mac without asking for the admin’s approval, which allows the pest to impose arbitrary system parameters while providing no simple way to override them. It’s also noteworthy that the attack is accompanied by a peculiar malicious process running in the background. This executable is visible in the Activity Monitor. In many recent cases, it’s called “productevent”. Therefore, to start the fix it’s necessary to terminate this process so that it doesn’t interfere with the subsequent cleaning steps.

To top it off, the app may collect personally identifiable information about the victims and their Macs, such as visited sites, searches made, IP addresses, and other sensitive data. Unscrupulous vendors tend to retain such details and sell them to advertisers or cybercrooks. Obviously, Search Pulse doesn’t belong inside a Mac unless it was wittingly installed, which is hardly ever the case. So, if redirects to home.searchpulse.net or search.searchpulse.net are giving you a hard time, be sure to follow the steps below and remove the infection.
