Coos Ransomware (sometimes called STOP Ransomware or DjVu Ransomware) is wide-spread encryption virus, that first appeared in December, 2017. Since then, lots of technical and design changes took place, and a few generations of malware changed. Ransomware uses the AES-256 (CFB-mode) encryption algorithm to encode user's files and after this last version appends .coos extensions. After encryption virus creates a text file _readme.txt, which is called "ransom note", where hackers disclose ransom amount, contact information, and instructions to pay it. STOP Ransomware with .coos file extensions use following e-mails: email@example.com and firstname.lastname@example.org. Authors of STOP Ransomware demand $980 for decryption of your files (also 50% discount offered if the ransom is paid within 72 hours) and give users 6 hours to answer. Statistics show, that hackers may not reply after getting the payment. So you won't receive their decryption tool. We do not recommend transferring any funds to such people. However, files encrypted by Coos Ransomware can be decrypted with help of STOP Djvu Decryptor from EmsiSoft, free decryption utility, that is able to decode .coos files for free. Before that, you need to kill the active process and remove the executable of STOP Ransomware, get anti-malware or anti-ransomware protection.
StreaminSearchs is an unwanted piece categorized as a browser hijacker. Software within this category targets Chrome, Mozilla Firefox, Microsoft Edge, and other browsers to dictate new settings. These settings are vividly-seen in the change of a homepage and search engine to
streaminsearchs.com. Some additional widgets ostensibly meant to improve browsing are also added along with the change of the previously-mentioned. Whilst they can seem to be useful and alleviate the usage, there are significant drawbacks that can damage your privacy. Browser hijackers are capable of gathering personal data (e.g. passwords, IP-addresses, geolocations, etc.) and selling it to third-party ventures. Moreover, instead of using the new search engine for showing results, it simply redirects to legitimate Yahoo.com. This is another useless feature that does not give any browsing advantage over competitors. Thus, our recommendation is to delete StreaminSearchs from your PC to ensure further safety of data.
Dharma is a ransomware family considered to be the biggest developer of ransomware infections. Lots of versions have been found attacking users with data encryption and ransom-demand messages. However, one of the recent versions spotted being active around is known as yoAD Ransomware. Alike similar viruses of this type, it assigns the new .yoAD extension with random ID and cybercriminals' e-mail to each piece of data stored on a compromised PC. For example, the original file like
1.mp4will get a look of
1.mp4.id-C279F237.[email@example.com].yoAD, or similarly. Such changes make your files are no longer accessible as any attempts to initiate them will be denied. Then, once this process gets to a close, the virus steps in with the creation of text instructions. They are presented in the FILES ENCRYPTED.txt document right on your desktop. As extortionists claim, the only way to restore your data is by contacting them via e-mail. Then, they will supposedly give you a crypto-wallet to send money in Bitcoin. After this, you will be given the necessary tools to restore your data. Unfortunately, this method does not fit everybody because amounts asked by cybercriminals can be astronomically high and not easy to pay.
Load20.biz represents a suspicious website meant to promote fake push-notifications. The moment users end up on this page, they see a dialog window requesting to allow web-notifications. If you respond to it as asked, your desktop will start receiving loads of advertisement messages. Such banners might look innocent, however, they can pose a real threat by redirecting people to unwanted or even malicious websites. One more danger brought along with banners can be related to data-surveillance. Websites that promote fake notifications, usually appear due to the presence of adware. This is a Potentially Unwanted Program that lurks inside of your PC inflicting such changes. Thus, because it is granted with permission to configure your browser, it can also gather and sell your personal data (e.g. passwords, geolocations, IP-addresses, banking details, etc.). The problem with such infections is that they are hard to remove for inexperienced people. Despite this, we have provided a list of versatile instructions that will help you get rid of Load20.biz and other viruses as well.
Qlkm Ransomware is a disastrous virus, that uses AES encryption algorithms to encrypt user's files. After encoding files obtain following extensions: .qlkm. The malware aims at encryption of personal data, such as documents, photos, videos, music, e-mails. Deep encoding makes those files unapproachable and decryption instruments available today cannot help in most cases. To start automatically each time the OS starts, the cryptographer creates an entry in the Windows registry key that defines a list of programs that start when the computer is turned on or restarted. To determine which key to use for encryption, Qlkm Ransomware tries to establish a network connection with its command server. The virus sends information about the infected computer to the server and receives the encryption key from it. In addition, the command server can send additional commands and modules to the virus that will be executed on the victim's computer. If the data exchange with the command server was successful, the virus uses the received encryption key (online key). This key is unique for each infected computer. If Qlkm Ransomware was unable to establish a connection with its server, a fixed key (offline key) will be used to encrypt files.
Crypto-Locker Mijnal is a ransomware-type infection that encodes personal data with AES+RSA algorithms. The application of such means that the assigned cipher is hard to break using traditional methods. In other words, it makes sure manual decryption does not take place after data is locked. Unfortunately, in most cases, it appears to be impossible indeed, but you should give it a try after reading this text. Alike other infections, Mijnal encrypts your data by changing a file extension to .mijnal. For example, a sample like "1.mp4" will be altered to "1.mp4.mijnal" and reset its original icon. After the encryption process gets to a close, the virus creates a text note called "README_LOCK.txt" that contains redemption instructions. The information presented inside is written in Russian, which means that developers mainly focus on the CIS regions. However, there are some English users that may be affected by it as well. If you are willing to decrypt your data as soon as possible, cybercriminals ask victims to open the attached link via the Tor browser and follow the instructions right there. Then, extortionists will more likely ask you to pay a certain amount in Bitcoin to gain access back to your data. Despite paying the ransom is usually the only method to overcome data encryption, we recommend against meeting any requests as it can be dangerous for your pocket and privacy as well.
