What is Minr?

Minr is a Monero cryptocurrency-mining service similar to Coinhive, Crypto-Loot, and CoinImp. As with these examples, Minr's service is legitimate - it provides web developers with a JavaScript API that can be embedded into a website. When entering a site, the user's computer resources are used to mine Monero. Some web developers, however, become greedy and start to abuse Minr. They do not notify users that their systems are being used to mine and do not limit the use of system resources. In this way, they utilize up to 100% of system resources without users' consent.

Minr scam

As mentioned above, Minr and the idea behind it are legitimate - developers have an additional tool to monetize their sites. Crypto mining is essentially a process by which computers solve mathematical equations. As a reward for a solved equation, the miner receives a fraction of a Monero coin. Note that an identical equation is solved by a number of computers from around the world simultaneously - the mined Monero coin is distributed amongst them. Minr provides a feature allowing users to limit use of visitors' computer resources, however, greedy developers remove this limit, since the more powerful the system, the more coins they can mine. Furthermore, JavaScript makes perfect use of system CPU resources. Therefore, CPU utilization can reach 100%. This causes system instability - it barely responds and might crash (resulting in permanent data loss). In addition, the CPU can overheat under certain circumstances (bad cooling system, high room temperature, and so on). By abusing Minr services in this way, developers can damage computer hardware. Note that an average home PC is not a good choice for mining cryptocurrency (the cost of electricity is typically higher than the revenue received). Furthermore, in most cases, users remain on sites for a few minutes only. Therefore, criminals attempt to embed their scripts into as many websites as possible. They do this in various ways. For example, cyber criminals hijack legitimate websites and stealthily inject them without consent. Criminals also create dozens of malicious sites that contain spurious content or display fake errors. These websites mine cryptocurrency and run scripts that prevent users from closing browsing tabs/windows. This is done to force users stay as long as possible. These sites are often promoted using potentially unwanted adware-type programs (PUPs).

Adware-type PUPs deliver coupon, banner, pop-up, and other similar advertisements. These can lead to various sites that mine cryptocurrency, contain malicious content, and even execute scripts that download/install malware. Therefore, even a single click can result in high-risk computer infections. Intrusive ads are delivered via tools that enable placement of third party graphical content on any site and, thus, most conceal visited website content, thereby significantly diminishing the browsing experience. Another important issue is data tracking. Potentially unwanted programs are likely to gather IP addresses, queries entered into search engines, URLs visited, pages viewed, keystrokes, geo-locations, and other information that might contain personal details. Once recorded, this data is shared with third parties (potentially, cyber criminals) who misuse private information to generate revenue. Therefore, the presence of a data-tracking app can lead to serious privacy issues. Eliminate all PUPs immediately.

Research shows that most potentially unwanted programs are virtually identical. By falsely claiming to enable "useful functions", they attempt to give the impression of legitimacy and trick users to install, however, potentially unwanted programs are designed only to generate revenue for the developers, whilst regular users receive no real value. Rather than enabling the functions promised, PUPs deliver intrusive ads and gather sensitive data, thereby posing a threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs are free for anyone to download on their official websites. Despite this, most infiltrate systems without permission, since developers proliferate PUPs using "bundling" and intrusive advertising methods. "Bundling" is essentially stealth installation of third party apps with regular software/apps. "Bundled" applications are hidden within various sections (for example, "Custom/Advanced" settings) of the download or installation processes. Developers do not reveal these installations. Further complicating the issue are many users who skip these procedure steps and click dubious ads, without understanding the possible consequences. This behavior often leads to inadvertent installation of various PUPs.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be very cautious when browsing the Internet and, especially when downloading/installing software. Intrusive ads may seem legitimate, but once clicked, redirect to gambling, adult dating, pornography, and other dubious sites. If you encounter these redirects, immediately check the list of installed apps/browser plug-ins and eliminate any suspicious entries. Furthermore, select "Custom/Advanced" settings, closely analyze each window of these procedures, and opt-out of all additionally-included programs. Avoid using third party downloaders/installers, since they are often monetized using the "bundling" method. We recommend that you download applications from official sources only, using direct download links. Using a legitimate anti-virus/anti-spyware suite is also essential. The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution.
