What is 4KSportSearchs?

4KSportSearchs is a browser hijacker that promotes 4ksportsearchs.com, the address of a fake search engine. Generally, apps of this type hijack browsers by changing their settings.

Furthermore, browser hijackers often collect details relating to users' browsing habits. People mostly download/install apps such as 4KSportSearchs inadvertently and, therefore, they are classified as potentially unwanted applications (PUAs).

What is MrJeck ransomware?

MrJeck is a malicious program within the ransomware classification. Systems infected with this malware have their data encrypted and users receive ransom demands for decryption (i.e., to unlock the files that have been rendered inaccessible).

When MrJeck encrypts, files are renamed according to this pattern: "[random_string].[MrJeck@Cock.Li]" (which consists of a random character string and the criminals' email address). For example, a file initially named "1.jpg" would appear as something similar to "kfaWvoAynolu04.[MrJeck@Cock.Li]" following encryption.

After this process is complete, ransom messages in "Read Me Please!.txt" files are created in compromised folders.

What kind of malware is Monero?

Ransomware is a type of malware that prevents victims from accessing their system or personal files and demands ransom payments. It encrypts files and keeps them inaccessible until the ransom is paid.

Usually, it displays or creates a ransom message that contains instructions about how to contact the attackers, pay the ransom, and various other details.

Monero displays a pop-up window and creates the "HOW TO DECRYPT FILES.txt" text file in folders that contain affected (encrypted) data.

It also changes the desktop wallpaper and renames encrypted files by appending the ".monero" extension. For example, "1.jpg" is renamed to "1.jpg.monero", "2.jpg" to "2.jpg.monero", and so on. Note that Monero belongs to the Xorist ransomware family.

What is DriverToolkit?

DriverToolkit is untrusted software endorsed as a device driver management tool. It supports various Windows versions and has an extensive database of drivers obtained from official sources.

This application can supposedly detect outdated and missing drivers and update/install them accordingly. Additionally, it can create backups for the drivers, restore and uninstall them, however, due to the dubious techniques employed to distribute DriverToolkit, it is categorized as a Potentially Unwanted Application (PUA).

Typically, software within this category is nonoperational and can have undisclosed and unwanted functionality.

What is MacCleanBooster?

MacCleanBooster is advertised to clean Mac computers for better performance. In fact, it is promoted on untrusted websites and developers use dubious methods to distribute it. Therefore, MacCleanBooster is categorized as a potentially unwanted application (PUA).

What is OperativeUnit?

OperativeUnit is an adware-type app with browser hijacker traits. Thus, it delivers intrusive advertisement campaigns and promotes fake search engines by modifying browser settings. Additionally, most adware programs and browser hijackers collect browsing-related information, and this application is also likely to have these data tracking capabilities.

Due to the dubious tactics used to distribute OperativeUnit, it is also classified as a Potentially Unwanted Application (PUA). One of the dubious techniques used to spread OperativeUnit is proliferation via fake Adobe Flash Player updaters/installers.

What is SkilledPanelSearch?

SkilledPanelSearch generates advertisements and alters the settings of browsers to promote a fake search engine. For this reason, SkilledPanelSearch is classified as not only an adware-type app, but also as a browser hijacker.

These apps often gather information relating to internet browsing activity, or even more personal information.

Typically, users install apps like SkilledPanelSearch onto their browsers or computers unintentionally. Therefore, SkilledPanelSearch and other apps of this type are also classified as potentially unwanted applications (PUAs).

This app is distributed through a deceptive installer, which appears similar to the installer for Adobe Flash Player.

What is LunarLookup?

LunarLookup is rogue software classified as adware. This application also possesses browser hijacker traits. LunarLookup operates by running intrusive advertisement campaigns, modifying browsers and promoting fake search engines. Furthermore, most adware type apps and browser hijackers have data tracking capabilities employed to monitor users' browsing habits.

Due to the dubious methods used to spread LunarLookup, it is also classified as a Potentially Unwanted Application (PUA). One of these dubious proliferation techniques is via fake Adobe Flash Player updates. Bogus software installers/updaters are also used to distribute Trojans, ransomware and other malware.

What is Ribd?

Ransomware is a type of malware that encrypts files and displays ransom messages on the screen (or creates a text file in affected folders). It keeps files inaccessible unless ransoms are paid.

Furthermore, ransomware often changes the file extensions of encrypted files. Ribd appends the ".ribd" extension. For example, "1.jpg" is renamed to "1.jpg.ribd", "2.jpg" to "2.jpg.ribd", and so on. It also creates the "_readme.txt" file (ransom message) in all folders that contain encrypted data.

Note that Ribd belongs to the Djvu ransomware family.

What is Games Search?

In most cases, apps such as Games Search hijack browsers by changing their settings. They are essentially used to promote fake search engines. Games Search promotes the games-search.net address in this way. It can also read browsing-related data and might be capable of accessing other, sensitive information as well.

Typically, users do not download or install browser hijackers intentionally and, therefore, Games Search and other apps of this kind are classified as potentially unwanted applications (PUAs).
