Decaf is categorized as a ransomware program designed to blackmail victims into paying money for the recovery of blocked data. Its first attacks were registered at the beginning of November 2021 and continue taking place across multiple users. The virus employs its own extension called .decaf which is assigned during encryption. An example of how encrypted files would like after encryption is this "1.pdf.decaf". It is impossible to blink the infection because all files lose their accessibility and icons as well. Upon successful installation of cryptographic ciphers, Decaf creates a text note named README.txt that contains info on how to recover your data. Cybercriminals say all server and PC data has been encrypted with strong algorithms preventing any third-party decryption. The only possible way to restore access to the entire data is to use a special "universal" decryptor stored by the extortionists. To learn further instructions regarding decryption, victims should write to the attached e-mail address (22eb687475f2c5ca30b@protonmail.com). From there, will be likely informed about the price of decryption software and ways to obtain it. As a rule, cybercrooks request their victims to send varying amounts of money in some cryptocurrency to their wallets. The range can fluctuate from hundreds to thousands of dollars for the restoration of data.

Polaris is a ransomware program that uses a combination of AES and RSA algorithms to encrypt users' data. Unlike other infections of this type, Polaris does not add any extension to the encrypted files. The only thing that changes is accessibility to files - victims are no longer eligible to open the stored data. In order to solve this, Polaris developers encourage their victims to read recovery instructions in a file called WARNING.txt. The text note creates at the end of encryption and says you should contact extortionists using e-mail communication (pol.aris@opentrash.com or pol.aris@tutanota.com). There is also an option to add cybercriminals on Discord instead. Whilst writing a message, victims should state the name of the company that got under attack. This is a clue that Polaris targets business networks so they could afford to pay the required ransom. The most common advice you may see on the web regarding ransom payments is to avoid them as much. This is true because many cybercriminals tend to fool their victims and not send any decryption tools eventually.

If you walk in the Activity Monitor, which is the equivalent to the Windows Task Manager, you will see a number of processes and resource consumption of it. If some of the tasks are highlighted red exceeding the amount of CPU usage, Mac becomes sluggish, overheating boosts fan speed producing a lot of sounds, and other disturbing effects that prevent you from normal usage. Kernel_task is simply the name of different processes reflecting additional information upon them. There are multiple reasons that can destroy Mac performance such as malware, bugged updates, wrong software configuration, and hardware problems. Unless taken seriously, this can reduce the lifespan of your processor, graphic card, or other components. We have gathered several methods that have been successful at dealing with kernel_task issues.

If you found your files have new .hamster extension and no longer accessible, then you are infected with a virus called Hamster Ransomware. Infections of this type hack your PC settings to run through encryption of data. They also apply some visual changes to make victims spot the result of infection. After successful encryption, you will see a file like 1.pdf change to 1.pdf.hamster and reset its default icon to blank. The virus will also create a text note called How To decrypt.txt. As stated in the note, Hamster Ransomware penetrated your network and blocked access to most of the data. In order to get it back, victims are instructed to contact cyber criminals with their assigned ID and purchase the tool for decryption. It is important that victims reach out to malware developers using TOX messenger, which should be installed in case of absence. The frauds also advise you to contact them within 72 hours since the attack. This way, the price for complete data recovery will be reduced. It is also mentioned the attackers will tell how they infiltrated your system and what can be done to fix the existing vulnerability in the future.

Hospitalhelper is the name of another ransomware infection. Although it is new, the virus copies traits of other popular versions. File encryption, new extension, and ransom note are the main changes brought by Hospitalhelper. For instance, a file like 1.pdf will change to something like this 1.pdf.hospitalhelper.5BB-DE6-0CC and reset its shortcut icon. While .hospitalhelper is a constant extension, 5BB-DE6-0CC represents random combination of letters reflecting a victim's ID. After your files have been altered this way, access to them will be no longer available. Hospitalhelper also creates a text note called !!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT that contains ransom instructions.
