What is d8yI+Hf7rX?

d8yI+Hf7rX is a potentially unwanted application (PUA), a browser extension that comes bundled with other apps of this type (e.g., Gdiview). Bundled apps are classified as PUAs because users often download and install them inadvertently. Note that d8yI+Hf7rX adds the "Managed by your organization" extension to Chrome browsers.

The purpose of d8yI+Hf7rX is unknown, however, it is likely that this app generates ads, changes browser settings, and gathers various information. In this way, d8yI+Hf7rX will function as adware and a browser hijacker.

What is the Go surfing browser hijacker?

Go surfing is a browser hijacker, which promotes the keysearchs.com fake search engine. Software within this category typically promotes search engines by making modifications to browser settings, however, Go surfing does not always modify browsers in this way (see below).

Go surfing is also a serious privacy concern, since it collects browsing-related information. Most users download/install browser hijackers inadvertently, and so they are also classified as Potentially Unwanted Applications (PUAs).

What is ReSearchConverter?

ReSearchConverter is dubious software that is categorized as a browser hijacker. Following successful installation, it makes alterations to browser settings to promote researchconverter.com (a bogus search engine).

ReSearchConverter also has data tracking capabilities, which are employed to monitor browsing activity and collect sensitive information extracted from it. Since most users download/install browser hijackers unintentionally, they are also classified as Potentially Unwanted Applications (PUAs).

What is Cosd?

Cosd belongs to the Djvu ransomware family. Its main purpose is to encrypt files and keep them inaccessible (unusable) unless a ransom is paid. Typically malware of this type uses strong encryption algorithms to encrypt files so that victims cannot recover files unless they pay.

Cosd ransomware also renames all encrypted files by appending its extension (".cosd") to filenames. For example, "1.jpg" is renamed to "1.jpg.cosd", "2.jpg" to "2.jpg.cosd", and so on. Additionally, it creates the "_readme.txt" files (ransom messages) in all folders that contain encrypted files.

What is the "Generate Bitcoin" scam?

"Generate Bitcoin" refers to a scam run on various deceptive websites. This scheme invites users to generate up to 0,2 BTC (Bitcoin cryptocurrency) each week for a relatively small fee.

In fact, this scam cannot generate the promised cryptocurrency - its sole purpose is to trick users into transferring Bitcoins to the scammers responsible. Therefore, you are strongly advised against using the fake "Generate Bitcoin" service.

Typically, users access deceptive/scam sites via mistyped URLs, redirects caused by intrusive ads, and by Potentially Unwanted Applications (PUAs).

What is Orcus?

Orcus is a Remote Access Trojan (RAT). Programs of this type are used to remotely access or control computers. Generally, these tools can be used by anyone legitimately, however, in many cases, cyber criminals use them for malicious purposes. They often trick people into installing these programs and then use them to steal various information to generate revenue.

What is Betarasite?

Betarasite is a form of malware that encrypts files and displays a ransom message. In this way, it prevents victims from accessing and using their files unless a ransom is paid.

This ransomware also renames all encrypted files by appending the ".betarasite" extension to filenames. For example, "1.jpg" is renamed to "1.jpg.betarasite", "2.jpg" to "2.jpg.betarasite", and so on.

What is 22btc ransomware?

22btc is a malicious program, which belongs to the Dharma ransomware family. It is designed to encrypt data and demand payment for decryption. I.e., systems infected with this malware have files stored on them rendered inaccessible and useless.

When 22btc encrypts, files are renamed following this pattern: original filename, unique ID assigned to the victims, cyber criminals' email address, and the ".22btc" extension. For example, a file originally named "1.jpg" would appear as something similar to "1.jpg.id-C279F237.[22btc@tuta.io].22btc" following encryption.

Once this process is complete, ransom-demand messages are created in a pop-up window and "FILES ENCRYPTED.txt" text file.

What is TechnologyMain?

TechnologyMain is a potentially unwanted application (PUA) that generates revenue for its developers by displaying advertisements, promoting a fake search engine, and collecting data. In this way, the PUA functions as adware and a browser hijacker.

Typically, users download and install apps like TechnologyMain unintentionally and thus are classified as PUAs.

What is Plam?

This ransomware belongs to the Djvu ransomware family.

Plam encrypts files (prevents victims from accessing or using them) and appends the ".plam" extension to filenames. For example, "1.jpg" is renamed to "1.jpg.plam", "2.jpg" to "2.jpg.plam", and so on.

Plam also creates a ransom message within the "_readme.txt" text file. This contains contact and payment information and can be found in all folders that contain encrypted files.
