Also known as Mimicry, ShivaGood Ransomware has by far no good intentions at all because it is designed to encrypt users' data and demand ransom payment in bitcoin. This malicious piece uses special cryptographic algorithms and assigns ".good" extension to multiple files (PDFs, documents, images, videos, etc.). For instance, 1.mp4 will be renamed to 1.mp4.good, and similarly. Once ShivaGood completes the encryption procedure, it will create a text file called HOW_TO_RECOVER_FILES.txt. This note contains information about data encryption. To decrypt it, extortionists ask you to contact them via e-mail and attach your personal ID that is mentioned in the note as well. Once done, frauds will reach back to you with payment instructions to obtain the decryption key. Additionally, cybercriminals propose to unlock 3 files (less than 10 MB) for free. This is a trick to prove their integrity since reality can differentiate significantly. They can simply extort money and forget about their promises.
Soldier Ransomware is a malicious piece that encrypts user's data and gouges their money to decrypt files. It was first discovered by security researcher Amigo-A. During the encryption process, all files get changed with the .xsmb extension that is attached at the end of a file. For instance, something like 1.mp4 will change its name to 1.mp4.xsmb and reset its icon. After all, the ransomware generates a text file (contact.txt) or image (contact.png) on the victim's desktop. As stated in these files, users have to send 0.1 BTC or 4 ETH through the linked address. Additionally, you can send up to 3 files to their e-mail for free decryption. It is also worth mentioning that Soldier Ransomware seems to be created and operated by a single person as the note suggests. Unfortunately, Soldier Ransomware is impossible to decrypt without the involvement of cybercriminals.
Roger is another form of Dharma family that encrypts data with unbreakable ciphers and demands victims to pay a ransom. When it infiltrates your system, all stored data will be retitled with the victim's ID, cybercriminal's e-mail, and .roger extension. To illustrate, a file like 1.mp4 will upgrade to 1.mp4.id-1E857D00.[firstname.lastname@example.org].ROGER". Note that IDs and e-mails may vary individually. After the virus finishes the file encryption, it will create a text file called FILES ENCRYPTED.txt on your desktop. In this note, people can familiarize themselves with the steps to unlock their data. For this, you should click on the attached link in the Tor browser and they will get back to you in 12 hours to instruct you on purchasing their decryption software. If not, then you should write to them by using a backup e-mail. Unfortunately, paying for the software might be a trap that will putt your finances under a risk.
STOP Ransomware or as it is often called DJVU Ransomware belong to the large family of file-encryption viruses with long history and multiple modifications. Currently, this is one of the most widespread ransomware. We won't go deep into technical details of the infection, but explain simple methods and chances to decrypt affected files and remove the virus. The first thing you should know, there are cases, that can be treated successfully, the bad news is - chances of a successful outcome are less than 5%. In this article we will observe variation that appends .covm extension to files. STOP Ransomware uses a similar pattern with all victims. It comes as a fake windows update from torrent websites runs executable to disable security programs and starts the encryption process of valuable files, such as docs, videos, photos, music. In the end it places ransom note (_readme.txt) file in every folder with encrypted files.
If you spotted that your browser settings have been changed, then it is because a browser hijacker is installed on your computer. After infiltration, this specific virus alters your homepage to Securedsearch.org which will be seen each time you boot a browser. Unfortunately, any attempts to restore the settings are useless since Secured Search immediately changes them back. Browser hijackers are supposedly meant to improve the browsing experience by adding various features. For example, Secured Search extension assigns a new securedsearch.org search engine that ostensibly generates more accurate and sorted results. However, after entering a query, you will be redirected to legitimate Yahoo.com. Not only browser hijackers can bother your browsing by showing intrusive ads, banners, and links without your consent, but they are also capable of gathering personal data (passwords, IP-addresses, geolocations, history, etc.) that can be sold to third-parties. Securedsearch.org is fake and brings no promised value, therefore, it needs to be removed from your PC to secure your data.
4solo.biz is another example of a browser-based scam that attempts to force users into clicking on the "Allow" button. Websites of such type can be visited inadvertently as a result of clicking on deceptive ads or banners, however, if you are constantly witnessing this page at the browser startup, chances are your PC is infected with adware. Developers of such pages exploit delusive headings like "Confirm you are not a robot", "Pass Captcha", "Click Allow to download a file", and others. If you followed their commands, then you might be experiencing a stream of ads on your desktop. Note that such ads can contain malicious redirects that may cause additional infections and steal your data away.
