What is search.terraarcade.com?

What is newchannel[.]club?

The newchannel[.]club website is virtually identical to hatnofort[.]com, terjuscalbuttont[.]info, ninghimpartidi[.]info and many others of this type.

When opened, it displays dubious content or causes redirects to other untrustworthy sites. Typically, people are redirected to newchannel[.]club by potentially unwanted apps (PUAs) that are installed on their browsers and they do not generally visit the site intentionally. PUAs collect data and serve users with advertisements.

What is "Hard Drive Safety Delete"?

"Hard Drive Safety Delete" is a tech-support scam promoted via a deceptive, untrustworthy website. The main purpose of these scam pages is to trick people into calling scammers who then try to extort money by offering purchase of dubious software or use of paid technical services.

Websites of this type cannot be trusted. They are often opened by potentially unwanted applications (PUAs) installed on the system. In addition to redirects, PUAs feed users with ads and gather browsing-related data.

What is Phoenix-Phobos?

First discovered by GrujaRS and belonging to the Phobos ransomware family, Phoenix-Phobos is high-risk ransomware designed to encrypt data and make ransom demands. During encryption, Phoenix-Phobos renames each file by appending the filenames with the ".phoenix" extension plus the victim's unique ID and developer's email address.

For example, "sample.jpg" might be renamed to a filename such as "sample.jpg.id[1E857D00-0001].[absonkaine@aol.com].phoenix". Updated variants of Phoenix-Phobos ransomware use ".[britt.looper@aol.com].phoenix" extension for encrypted files. In addition, Phoenix-Phobos places the "info.hta" (which is also opened) and "info.txt" files on the desktop.

What is hatnofort[.]com?

The natnofort[.]com website operates in a very similar manner to other pages of this type such as arberittertwa[.]info, vercallactont[.]com, and butitereventwil[.]info. When opened, it causes redirects to other rogue sites or simply displays dubious content.

People do not generally arrive at this site intentionally - mostly this is due to potentially unwanted applications (PUAs) installed on their browsers. PUAs usually cause unwanted redirects, serve users with ads, and collect data.
