What is Crapsomware?

Discovered by Petrovic, Crapsomware is a ransomware-type program designed to encrypt data and demand payment for decryption tools. I.e., the files affected by Crapsomware are rendered inaccessible, and victims are asked to pay a ransom to unlock them.

During the encryption process, files are appended with the ".crap" extension. For example, a file initially named something like "1.jpg" would appear as "1.jpg.crap", "2.jpg" as "2.jpg.crap", etc.

Following the completion of this process, a ransom message is displayed in a pop-up window.

What is fastcaptcharesolve[.]com?

fastcaptcharesolve[.]com is a rogue website, sharing many similarities with thedailyrobotcheck.site, bestletherservice.me, wholefreshposts.com, and countless others. This page operates by delivering dubious content and redirecting visitors to other untrusted/malicious sites.

Users rarely access web pages of this kind intentionally - most are redirected to them by intrusive ads or installed Potentially Unwanted Applications (PUAs). This software does not require explicit permission to infiltrate systems, and thus users may be unaware of its presence.

PUAs cause redirects, run intrusive ad campaigns, and collect browsing-related information.

What is ardoppoprus[.]biz?

Sharing many common traits with thedailyrobotcheck.site, bestletherservice.me, wholefreshposts.com, filemix-1.com, pushails.com, and thousands of others, ardoppoprus[.]biz is an untrusted website. Visitors to this site are presented with dubious content and/or are redirected to other rogue or possibly malicious pages.

Most users enter these websites inadvertently - they are redirected to them by intrusive advertisements or installed Potentially Unwanted Applications (PUAs). These apps do not need explicit user permission to infiltrate devices. PUAs have dangerous functionality such as causing redirects, delivering intrusive advertisement campaigns, and collecting browsing-related information.

What is the Ghost ransomware?

Ghost is the name of a ransomware-type program. It is designed to encrypt and rename data - in order to demand ransoms for the decryption tools. In other words, files affected by Ghost malware are rendered inaccessible, and victims are asked to pay - to recover access to their data.

During the encryption process, filenames are appended with an extension, which differs throughout Ghost variants.

Versions of this ransomware have been observed adding the ".BeHappy", ".D0ntW0rry", ".GetMoney", ".Gets", ".KrB3Ha99y", ".KrDontCry", ".Spanishghost", ".Welcomeghost", ".dkghost", ".jpghosts", ".phantom", ".rsaes", ".ryuks", and ".vjiszy1lo" extensions to the files.

Therefore, a file originally named something like "1.jpg" could appear as "1.jpg.BeHappy", "1.jpg.D0ntW0rry", "1.jpg.GetMoney", "1.jpg.Gets", etc. - depending on the ransomware variant.

Once the encryption process is complete, ransom notes - "HOW_CAN_GET_FILES_BACK.txt" and "HOW_CAN_GET_FILES_BACK.rtf" - are dropped into compromised folders.

What is JoJoCrypt?

Ransomware is a type of malware that blocks access to files stored on the infected computer by encryption and displays (or creates) a ransom message to demand payment.

Commonly, ransomware also renames encrypted files. JoJoCrypt (also known as JoJoCrypter) appends the ".jojocrypt" extension to filenames. For example, "1.jpg" is renamed to "1.jpg.jojocrypt", "2.jpg" to "2.jpg.jojocrypt", and so on.

This ransomware variant also creates the "how to recover your files.txt" text file in all folders containing encrypted files.

What is 1stkissmanga[.]com?

1stkissmanga[.]com is an untrusted website, hosting various manhua, manhwa, and manga series. I.e., this site allows users to read Chinese, Korean, and Japanese comics online.

As well as infringing copyright laws, this website also uses rogue advertising networks. Therefore, visitors to 1stkissmanga[.]com are presented with dubious/dangerous content and redirected to other bogus and even malicious pages.

You are strongly advised against visiting and/or using 1stkissmanga[.]com.

What is searchmy.co?

searchmy.co is a fake search engine. Rogue search engines are usually unable to generate unique results, and simply collect users' data. Fake web search engines are promoted by Potentially Unwanted Applications (PUAs) classified as browser hijackers.

The software promoting searchmy.co has been observed adding the "Managed by your organization" feature to Google Chrome browsers. Browser hijackers cause redirects to their associated search engines by making modifications to browser settings.

Additionally, most browser hijackers have data tracking capabilities that are used to record browsing activity and collect sensitive information extracted from it.

What is Backup ransomware?

The Backup ransomware variant belongs to the VoidCrypt ransomware family. Malware of this type generally encrypts files and displays ransom-demand messages, however, Backup creates "Decrypt-me.txt" text files in all folders that contain encrypted data rather than displaying ransom messages.

This ransomware also renames encrypted files by appending the unlockdata@criptext.com email address, a string characters, and the ".Backup" extension. For example, "1.jpg" is renamed to "1.jpg.[unlockdata@criptext.com][MJ-XP0964371852].Backup", "2.jpg" to "2.jpg.[unlockdata@criptext.com][MJ-XP0964371852].Backup", and so on.

What is searcher4u.com?

searcher4u.com is a fake search engine. In most cases, addresses like searcher4u.com are promoted through potentially unwanted applications (PUAs), for example, adware-type applications, browser hijackers.

searcher4u.com is promoted using a browser hijacker called PDFConverter4u, however, it is likely that other PUAs also promote this fake search engine.

Most users do not download/install PUAs or use fake search engines intentionally. Furthermore, browser hijackers are often designed to collect information relating to users' browsing activities.
