What is pesqueralosmonos[.]com?

pesqueralosmonos[.]com is a rogue website sharing common traits with dolohen.com, essaemiaaut.com, trynotify.com, and many others. It presents visitors with highly dubious content and generates redirects to other untrustworthy and malicious web pages.

Few users enter pesqueralosmonos[.]com intentionally - most are redirected to it by intrusive ads or Potentially Unwanted Applications (PUAs). These apps do not need explicit user permission to be installed onto devices. PUAs cause redirects, run intrusive advertisement campaigns, hijack browsers and track data.

What is startrafficc[.]com?

Virtually identical to redlabellondon.com, becausenightisbetter.com, and newsredirect.net, startrafficc[.]com is yet another rogue website. Visitors to it are presented with dubious and harmful content. They can also be redirected to other untrustworthy or even malicious web pages.

Few users enter these web sites intentionally - typically, they are redirected by intrusive ads or Potentially Unwanted Applications (PUAs) already present on the system. Note that these applications do not need express permission to be installed onto devices.

After successful infiltration, PUAs cause redirects, run intrusive ad campaigns and gather information relating to browsing activity.

What is convertisseur-youtube-mp3[.]net?

convertisseur-youtube-mp3[.]net is presented as a Youtube downloader. It converts Youtube videos (via links or titles) into MP3 and MP4 files, which users can then download.

As well as infringing copyright law, it uses rogue advertising networks. Therefore, this site generates redirects to various untrustworthy and potentially harmful pages. Additionally, visitors are presented with unwanted, dubious content.

What is centersourceoffreeupgrade[.]best?

The centersourceoffreeupgrade[.]best website encourages visitors to update Adobe Flash Player. In fact, it distributes a fake updater that does not update Flash Player, but simply installs some unwanted, potentially malicious software. We strongly advise against download anything from centersourceoffreeupgrade[.]best or other similar web pages.

In most cases, people do not visit websites such as centersourceoffreeupgrade[.]best intentionally - they are usually redirected to them by other dubious sites, deceptive ads, or potentially unwanted applications (PUAs) that are installed on their browsers.

What is mao1.club?

There are many fake search engines on the internet, including mao1.club. They are supposedly legitimate search engines that enhance the browsing experience (deliver fast, accurate results, and so on), however, do not trust mao1.club or other search engines of this type.

They are usually promoted using rogue download or installation set-ups that cause modification of browser settings. Furthermore, this particular search engine might be related to another fake search engine called qip.ru

What is mainsiteofupdatenow[.]best?

mainsiteofupdatenow[.]best is a deceptive website used to distribute a fake Flash Player updater. It attempts to trick people into downloading and installing unwanted software through the setup of a fake updater.

Typically, people do not often visit websites such as mainsiteofupdatenow[.]best intentionally - they are redirected to them by potentially unwanted applications (PUAs) that are already installed on their browsers and/or operating systems.

We strongly recommend against download anything from websites such as mainsiteofupdatenow[.]best - you should also remove all PUAs that could be responsible for opening them.

What is MMDecrypt?

MMDecrypt ransomware encrypts files and changes their extensions, creates two ransom messages, displays a pop-up window and changes the desktop wallpaper. It renames all encrypted files by appending the ".TRSomware" extension to filenames. For example, "1.jpg" becomes "1.jpg.TRSomware".

It stores the "@Lütfen_Beni_Oku!@.txt" and "@Please_Read_Me@.txt" text files (ransom messages) in all folders that contain encrypted files.

It changes the wallpaper by using an image called "@Wallpaper@.png" and displays a pop-up window by launching the "@MMDecrypt0r@.exe" executable file. Both of these files can be found on the desktop. MMDecrypt is a new variant of KesLan ransomware and was discovered by GrujaRS.

What is Tor+?

Discovered by S!Ri, Tor+ is a malicious program classified as ransomware. This malware operates by encrypting data and demanding payment for decryption tools/software. During the encryption process, files are appended with the ".Tor+" extension. For example, "1.jpg" appears as "1.jpg.Tor+", and so on for all affected files.

Once this process is complete, Tor+ opens a pop-up window, which contains the ransom message.

What is onestream[.]best?

onestream[.]best is a dubious website, which is usually opened by installed potentially unwanted applications (PUAs). Therefore, most people do not visit onestream[.]best (or other similar pages) intentionally. More examples of similar sites include trynotify[.]com, lulachu[.]com and redlabellondon[.]com.

When visited, onestream[.]best loads dubious content or opens other untrustworthy web pages. Most PUAs also gather information and display ads.

What is Buer Loader?

Buer Loader (BuerLoader) is trojan-type malicious software designed to cause chain infections (i.e., download/install additional malware). Since August 2019, it has been actively sold in underground markets. It has been observed spreading TrickBot, KPOT, Smoke Loader and Amadey malware.

Due to its presence on these marketplaces, Buer Loader can be used to spread a wide variety of other malicious content. The aforementioned infections were noted to proliferate via email spam campaigns and exploit kits (toolkits exploiting security weaknesses of various applications).
