Ox4444 Ransomware

What is Ox4444?

Ox4444 is a virus categorized as ransomware and is a new variant of high-risk malware called GlobeImposter. Once a computer is infected with Ox4444, this virus encrypts all (or most) files and makes them unusable. Furthermore, Ox4444 adds the ".Ox4444" extension to each encrypted file.

For example, "sample.jpg" is renamed to "sample.jpg.Ox4444". This ransomware also places a "HOW_TO_BACK_FILES.txt" text file in folders that contain encrypted files.

   
Search.hweathernation.co Redirect

What is search.hweathernation.co?

search.hweathernation.co is one of many fake search engines. According to the developers, it gives access to weather forecast websites. This site may seem legitimate and useful, however, developers promote it using a browser hijacker called Weather Nation.

Most browser hijackers are categorized as potentially unwanted applications (PUAs). Weather Nation is no exception, since it is often installed without permission. Furthermore, this PUA and search.hweathernation.co gather data relating to users' browsing activity.

   
Pushthenme.info POP-UP Redirect

What is pushthenme.info?

pushthenme.info is one of many rogue websites designed to cause redirects to other dubious sites. It is almost identical to ukcontentdelivery.info, click.dialog.support, whateveryf.info, ariocroft.com, and dozens of other rogue sites.

Research shows that many users visit pushthenme.info inadvertently - they are redirected by potentially unwanted applications (PUAs) or intrusive advertisements. Potentially unwanted applications typically infiltrate systems without permission. As well as causing redirects, they deliver intrusive advertisements and monitor web browsing activity.

   
Dharma-tron Ransomware

What is Dharma-tron?

Discovered by Michael Gillespie, Dharma-tron is a high-risk ransomware-type virus (a variant) belonging to the Dharma ransomware family. When a computer is infected with this virus, most (or all) files become unusable. Dharma-tron encrypts the files and renames them by adding the ".tron" extension with an ID and email address at the end of the filename.

For example, "1.jpg" becomes "1.jpg.id-1E857D00.[xtron@cock.li].tron" after encryption. The virus also creates a "FILES ENCRYPTED.txt" text file that contains information about how to contact cyber criminals (Dharma-tron developers) and displays a pop-up window with more details.

   
Ukcontentdelivery.info POP-UP Redirect

What is ukcontentdelivery.info?

ukcontentdelivery.info is one of many rogue websites (similar to click.dialog.support, whateveryf.info, and persubscribe.com) that lead visitors to other untrustworthy sites.

Typically, people do not visit this website intentionally - they are redirected to ukcontentdelivery.info by potentially unwanted applications (PUAs) or intrusive ads. PUAs often infiltrate computers without permission, deliver intrusive ads, and collect data relating to users' browsing habits.

   
YuALook Ransomware

What is YuALook?

YuALook is high-risk ransomware developed to encrypt files. Malware researcher S!Ri was the first to discover this virus. After successful infiltration, YuALook encrypts most stored data and renames each file using the "[random_string].Welcome!" pattern.

For instance, "sample.jpg" might be renamed to a filename such as "^SMBdtB.Welcome!". Encrypted data instantly becomes unusable and indistinguishable. Yet encryption is not the only feature of this malware - YuALook also generates a text file ("D_E_C_R_Y_P_T.txt"), placing a copy in every existing folder.

What is "Your Mojave Is Infected With (3) Viruses!"?

"Your Mojave Is Infected With (3) Viruses!" is a fake virus alert message. These fake messages are usually displayed on deceptive and untrustworthy websites.

In most cases, users are forced to visit these sites by potentially unwanted applications (PUAs) that cause redirects to dubious websites, deliver intrusive ads, and record personal information. Generally, users install these unwanted apps inadvertently.

   
Your OS High Sierra Is Infected With (3) Viruses! POP-UP Scam (Mac)

What is "Your OS High Sierra Is Infected With (3) Viruses!"?

Fake virus alert messages such as "Your OS High Sierra Is Infected With (3) Viruses!" usually appear only on untrustworthy, deceptive websites. Most users arrive at these websites unintentionally - they are redirected to them by potentially unwanted applications (PUAs).

Typically, these apps infiltrate systems without users' consent. Once installed, they cause redirects to other untrustworthy websites [similar to the one that displays the "Your OS High Sierra Is Infected With (3) Viruses!" fake message]. PUAs also deliver ads and collect data.

   
Search.hcrimereport.co Redirect

What is search.hcrimereport.co?

search.hcrimereport.co developers promote this site as a search engine that provides quick access to 'useful content' from various report providers. In fact, search.hcrimereport.co is promoted using the Crime Report browser hijacker that is categorized as potentially unwanted application (PUA).

Typically, users install browser hijackers such as Crime Report unintentionally. Furthermore, search.hcrimereport.co and Crime Report record information relating to users' browsing activity.

   
Kraken Cryptor v2.2 Ransomware

What is Kraken Cryptor v2.2?

Kraken Cryptor v2.2 is a new variant of high-risk ransomware called Kraken Cryptor. Malware security researcher Marcelo Rivero was the first to discover this virus. After successful infiltration, it encrypts most stored data and renames all compromised files using the "[random_string].[random_extension]" pattern.

For example, "1.jpg" might be renamed to a random filename such as "VxYOJEXNQKBEjYOM.HGVJS". Encrypted data instantly becomes unusable and indistinguishable. Following successful encryption, Kraken Cryptor v2.2 changes the desktop wallpaper and generates a text file ("Instructions-[random].txt"), placing a copy in every existing folder.
