What is Vultur?

Vultur is a malicious program classified as a RAT (Remote Access Trojan). Malware within this classification operates by enabling remote access and control over infected devices. Vultur targets Android operating systems. This malicious software seeks to obtain victims' online banking and cryptocurrency wallet credentials.

Australian, Italian, and Spanish banks were amongst the most targeted by this trojan; smaller campaigns were focused on Dutch and United Kingdom banking institutions. Additionally, the list of cryptowallets targeted by the Vultur RAT is extensive.

What is Music Search for Chrome?

Music Search for Chrome is a browser extension endorsed as an easy access tool to music-related online content. It is supposedly capable of sensing search intent for music (e.g., songs, singers, etc.) and insert quick links to the address (URL) bar suggestions. However, this piece of software promotes the amazingossearch.com fake search engine by making changes to browser settings.

Due to this, Music Search for Chrome is classified as a browser hijacker. Additionally, it spies on users' browsing activity. Since most users download/install browser hijackers unintentionally, they are also deemed to be PUAs (Potentially Unwanted Applications).

What is ourtopstories[.]com?

The main purpose of the ourtopstories[.]com website is to promote other questionable sites and show deceptive content. It is similar to okaynotification[.]com, maxy-tax[.]com, welftheraz[.]space, and a great number of other pages. It is important to mention that users do not open pages like ourtopstories[.]com intentionally.

What is BlackMatter ransomware?

BlackMatter is a piece of malicious software categorized as ransomware. It operates by encrypting data for the purpose of making ransom demands for the decryption tools. In other words, files affected by BlackMatter are rendered inaccessible, and victims are asked to pay - to recover access to their data.

During the encryption process, files are appended with an extension consisting of a random character string. For example, a file initially named "1.jpg" would appear as something similar to "1.jpg.k5RO9fVOl". After this process is complete, the ransomware changes the desktop wallpaper and created a ransom note - "[random_string].README.txt" (e.g., k5RO9fVOl.README.txt).

BlackMatter is likely to be the rebranded DarkSide ransomware, as there is evidence (e.g., matches in unique encryption routines, similarities in color schemes and language used in Tor websites, etc.) to support this claim. DarkSide's operation was shut down after their servers and cryptocurrency were seized following the Colonial Pipeline ransomware incident.

What is PC Accelerator?

Developers present PC Accelerator as a great tool to optimize and speed up your computer. Initially, this app may seem legitimate and useful, however, PC Accelerator is categorized as a potentially unwanted program (PUP). PC Accelerator often infiltrates systems without permission and provides no real value for regular users.

What is MultiplySearch?

MultiplySearch is an adware-type application with browser hijacker traits. It operates by running intrusive advertisement campaigns, making modifications to browser settings and promoting fake search engines. Additionally, most adware-type apps and browser hijackers collect browsing-related information.

Due to the dubious methods used to proliferate MultiplySearch, it is also classified as a Potentially Unwanted Application (PUA). One of the methods used to distribute this app is via fake Adobe Flash Player updates. Bogus software updaters/installers are used to spread PUAs, Trojans, ransomware and other malware.

What is Coronavirus Track and trace result email virus?

It is popular among cybercriminals to use the COVID-19 pandemic as an opportunity to trick people into making money transactions, providing personal information, or installing malicious software on their computers. In this particular case, cybercriminals attempt to deliver malware via coronavirus-themed email.

What is okaynotification[.]com?

Okaynotification[.]com is a rogue website sharing many similarities with maxy-tax.com, welftheraz.space, my-live-videos-leakes.com, and thousands of others. It operates by loading dubious content and/or redirecting visitors to various sites (likely unreliable or malicious ones).

These webpages are seldom accessed intentionally; most users get redirected to them by rogue pages, intrusive adverts, or installed PUAs (Potentially Unwanted Applications). These apps can infiltrate systems without user consent, and cause redirects, run intrusive advertisement campaigns, and collect browsing-related data.

What kind of application is Mulkey?

Mulkey is an adware-type application. It operates by running intrusive advertisement campaigns. Additionally, most similar adware-types have browser-hijacker traits (i.e., browser modification in promotion of fake search engines) and have data tracking abilities. Hence, Mulkey likely has such functionalities.

Due to the questionable methods used to distribute Mulkey, it is classified as an unwanted application. This app has been observed being spread via fake Adobe Flash Player updates. It is noteworthy that fraudulent updaters/installers proliferate not only dubious apps but also malware (e.g., trojans, ransomware, cryptominers, etc.).

What is CHRB ransomware?

CHRB belongs to the Matrix ransomware family. This ransomware variant encrypts files, changes their filenames by using a certain pattern, and creates a document file with a ransom note in it (the "!README_CHRB!.rtf" file). CHRB renames files by replacing their filenames with "[RecoveryData1@cock.li].[random_string].CHRB".

For example, CHRB renames a file named "1.jpg" to "[RecoveryData1@cock.li].0BBiWinX-BGydsThw.CHRB", "2.jpg" to "[RecoveryData1@cock.li].0BBiWinX-BGydsThw.CHRB", and so on. The ransom note created by CHRB contains instructions on how to contact the attackers and other details regarding data decryption.
