Distribution of TechSignalSearch
TechSignalSearch is a nasty application for Mac which has been reported to interrupt regular browsing sessions without users’ permission. Since this undesired program could be misused for the distribution of malicious files its presence in the browser could endanger the overall security of targeted Mac operating systems. At the moment security experts have not been able to identify a single tactic that is being used to infect the targets. We presume that the bad actors are using several of the most important methods to carry out malicious campaigns.
A common way of setting redirect attacks like TechSignalSearch is the use of email spam messages. They may directly distribute malicious file attachments containing scripts that lead to an infection. Other cases can utilize complex social engineering tricks and hyperlinks that are specifically made to confuse the intended targets into infecting themselves. Two more scenarios that are used in combination with email messages rely on infected files used as payloads ‒ documents and software installers.
- Infected Software Installers ‒ The criminals craft malicious packages made out of legitimate software installers. They are taken from the official vendor download sites, modified and then posted on online sites or attached (either as file attachments) or linked in the email messages.
- Infected Documents ‒ They represent dangerous files that usually come in the form of some of the most popular document types: rich text documents, spreadsheets and databases. When the users open them up a notification prompt will ask them to enable the built-in scripts (macros). If this is done then the malware is installed on the victim computer.
Malicious browser plugins carriers of TechSignalSearch and other associated programs can be uploaded to hacker-controlled sites and P2P networks like BitTorrent as well. The hacker operators frequently utilize template design, text and images to create portals that look like legitimate download sources. They may also use domain names that are very similar to legitimate sites and advertise them via pop-ups or ad networks.
The undesired program associated with TechSignalSearch can be found in numerous malware toolbars. They are usually made for the most popular web browsers installed on macOS: Safari, Mozilla Firefox, and Google Chrome. They can be distributed on illegal download sites or even on the browsers repositories (such as the Chrome Web Store for Google Chrome) using fake developer accounts.
Impact of TechSignalSearch Mac PUP
TechSignalSearch has been classified as a potentially unwanted program that harasses online users by delivering numerous intrusive ads in their browsers.
Apparently, in an attempt to spread this adware program the company owner (which currently remains unknown) bundles it with other supposedly useful free programs and then trick users into installing the PUP along with the primary app. This practice guarantees that TechSignalSearch’s owners will monetize their project.
TechSignalSearch Mac app is known to act like a typical adware program so its primary purpose is to deliver as many ads to infected users as possible. This is due to the fact that the owners of TechSignalSearch get paid each time you click on an ad displayed by their nasty service. The ads may appear during browsing sessions or even when your browser is closed.
The intrusive ads can slow down the performance of the browser and the whole system as well. Crashes may happen at times. All pop-ups, pop-unders, images, banners and other types of ads injected by TechSignalSearch could display phrases like:
- Powered by Tech Signal Search
- Ads by Tech Signal Search
- Promoted by Tech Signal Search
- Displayed by Tech Signal Search
- Advertised by Tech Signal Search
Additionally, once TechSignalSearch establishes its malicious files on the system it is able to harvest specific details from your system and browsers it affects. It is a common practice of undesired programs like the discussed one. This could be explained by the fact that malicious intenders attempt to build a complete profile of the victims with all their interests and patterns of online behavior. Then they could deliver targeted content or even sell the records to third-parties of unknown origin.
