FileEngineering is an example of ransomware-infection configuring files of victims to restrict access to them. Most of the time, users do not spot malware coming into the systems. Once upon a time, they end up seeing their data changed and locked from regular access. FileEngineering does it this way - by assigning victims' ID, cybercriminal's e-mail address, and .encrypted extension at the of the files. There are two versions of FileEngineering being spread around the web. The only difference is in using different e-mail addresses to contact swindlers. For example, you may see your data appear as 1.mp4.id=[BE38B416] Email=[FileEngineering@mailfence.com].encrypted or id=[654995FE] Email=[FileEngineering@rape.lol].encrypted depending on which version affected your PC. Then, the next step of FileEngineering's activity is creating a note called Get your files back!.txt that contains information regarding decryption. Inside of it, the information is addressed by a so-called security engineer. He says that you should contact him via e-mail and pay some amount of Bitcoin. Then, he will return your files decrypted and give some tips on improving your safety. Before that, you are also allowed to send a small file to prove he can unlock your data. Trusting cybercriminals is always a huge risk, so it is up to you whether you want it or not. If files are not of big value to you, you can simply delete FileEngineering and continue using your PC.

Sun or SunCrypt is classified as cryptovirus attacking systems to encrypt personal data. It started its journey in October 2019 and continues its presence infecting users until these days. The moment SunCrypt can be spotted in your PC is when it changes your files by adding the .sun extension. It was also heard about another version of SunCrypt which applies a string of random symbols instead of extensions. A change to something like this 1.mp4.sun or 1.mp4.G4D3519X58293C283957013M35DC8A2V0748D9845E7A5DBD6590E3F834C4638 means you are no longer allowed to access your data. To recover it back, SunCrypt creates a text notes (DECRYPT_INFORMATION.html or YOUR_FILES_ARE_ENCRYPTED.HTML) that contain ransom instructions. Although SunCrypt is mainly oriented towards English-speaking users, you have a possibility to switch between German, French, and Spanish as well. This by far increases the traffic of victims allowing developers to extend their business. As stated in the note, victims have to install the Tor browser and click on the "Go to our website" to purchase the decryption software. The required fee may vary based on the individual case, however, no matter how low or high it is, we recommend against going for such a risk.

Xbox Game Bar is a great utility allowing users to monitor resources of GPU, CPU, RAM, and many other features like sound change. Fast access to main functions and keeping track of your PC is always a good thing to have, especially with Xbox Game Bar being officially free in Microsoft Store. It is indeed a very useful program alleviating gaming and overall usage. Unfortunately, the community has raised a discussion concerning the 0x803F8001 error, which prevents users from managing the app correctly. The issue is usually followed by a message saying "Xbox Game Bar is currently not available in your account. Make sure you are signed in to the Store and try again. Here’s the error code, in case you need it: 0x803F8001". The problem started occurring after a server-side change made on November 5. It is also known that this problem covers users with Windows 10 version 1809 or fresher. For now, the main solution is up to the Microsoft team, however, as they have not dealt with this error just yet, we will suggest a couple of steps capable of solving the issue, at least temporarily.

Known to be distributed via mimicked versions of legitimate apps (e.g. NordVPN, Adguard VPN, TunnelBear VPN, The Great Suspender), Oksearch.org represents the address of a fake search engine working on Microsoft Edge and Google Chrome browsers. During the study, it was recorded that users land on oksearch.org after clicking on generated results provided by Google or Bing. It acts as part of the chain redirecting people to suspicious pages. Such a change may be influenced by third-party add-ons installed in your browser, so check the list of installed extensions. Note that unwanted add-ons can bear the threat of data-surveillance. Passwords, geolocations, IP-addresses, and other sensitive data can be collected and sold for revenue purposes. Disabling or removing them should seal the problem, so try to do it first. If Oksearch.org keeps coming back no matter what, there is a possibility that your PC is infected with a potentially unwanted program.

Dharma-259 is a ransomware-type infection belonging to the Dharma family. This group of developers has brought the biggest impact to the malware industry. Having a range of malicious programs, 259 compliments the list, and encrypts personal data with strong algorithms that prevent users from regular access. As a result, all data change its name with a string of digits including personal ID, cybercriminal's e-mail, and .259 extension at the end of each file. For instance, ordinary 1.mp4 will experience a change to something like this 1.mp4.id-C279F237.[259461356@qq.com].259 and reset its default icon. Then, once the encryption process gets to a close, the virus force-opens a pop-up window and creates a text note called FILES ENCRYPTED.txt, both of which contain information upon data recovery. As stated in both pop-up and note, victims have to contact swindlers via e-mail attaching personal ID. In addition to that, you are allowed to send up to 1 file (less than 1 MB) for free decryption. Then, once extortionists receive your message, you will be guided with steps on how to purchase decryption software. Sometimes, the required fee may skyrocket beyond the limits, becoming unaffordable for most of the users. Even if you are ready to enrich cybercriminals buying their software, we recommend you against it, because most users report a high-risk of being fooled and not obtain any tools to restore the data at all.

Thewowfeed.com is a suspicious page aimed to promote various ads. It does so by displaying a push-notification window asking to click on the "Allow" button. Originally, push-notifications is a great feature alleviating user experience. It helps you track news and other information published on websites. For example, if you subscribe to push-notifications on the New York Times, you will receive its news and articles right on the desktop. Unfortunately, because of the growing popularity of such a feature, some malefactors started abusing it to promote low-quality content for earning money. Displayed banners and ads delivered by Thewowfeed.com and similar domains, can be extremely annoying and dangerous since they might lead to fishing pages, adult websites, and other types of resources spreading viral content. Software with such capabilities is often categorized as adware. Sometimes, it can be hard to remove it due to certain values installed in your system.

Developed by a group of Turkish extortionists, SifreCikis is a ransomware infection encrypting personal data and demanding a fee for recovery. It creates a strong cipher on sensitive data using AES and RSA algorithms. As a result, the decryption of files becomes hard to pull off, even with third-party tools. All data encrypted by SifreCikis obtains a new extension based on these patterns: .{random-alphanumerical-sequence}. For example, a file like 1.txt will change to something like this 1.txt.E02F4934FC5A. Then, after the encryption is done, users encounter a note called ***NA*** that contains ransom instructions. Unfortunately, the content of the note is hard to conceive for non-native speakers, however, a group of researchers translated it and outlined some key information. It claims that you should contact cyber criminals via e-mail and attach your personal ID in the message topic. Then, you will receive further instructions to purchase the decryption software (500$ in BTC). If there is no response from the extortionists, you should read the information through the link in the Tor browser. Malware researchers spotted the domain name starting with sifrecikx, which is consonant with sifre cikis (meaning "cipher/password + exit" in Turkish). Also, during the investigation researchers defined that SifreCikis could be a brother of SifreCozucu, as it looks very similar having minor differences.

StreamBee is an unwanted extension configuring your default search engine to provide ostensibly useful features. Software with such capabilities is usually treated as browser hijackers. Actually, users can see that StreamBee shows results from the legitimate Google system. This is true, however, it also uses a third-party engine called keysearchs.com that can be seen glimpsing in the search bar during the usage. It is usually done to generate non-existent traffic through a chain of shady ads and banners. By doing so, extortionists earn a good chunk of money channeled to the promotion of their business. As long as StreamBee can spectate and gather your data (passwords, IP-addresses, geolocations, etc.), we strongly insist on removing this piece from your PC, all for the sake of your safety. Follow our guide below to perform complete removal without traces.
