What is Karl Ransomware?
Karl Ransomware might be a devastating surprise to any user who does not back up his files and does not feel like paying around $500 to restore them. The malicious application locks all personal data and shows a note claiming a victim must pay to receive a tool that can decrypt all files. Of course, there are no guarantees such a tool will reach you. Thus, doing as told might result in you losing not just your data, but also a considerable sum of money. If you want to know more about the malware before choosing what to do, we encourage you to read our full article. On the other hand, if you have already decided not to comply with the hackers’ terms, you could erase Karl Ransomware by following our removal instructions provided below this text. Our researchers say it might be best to deal with the malware immediately since it could relaunch when the system restarts and encrypt more files. If deleting it manually seems too tricky, you can use a legitimate antimalware tool instead.
Where does Karl Ransomware come from?
Knowing how hackers spread threats like Karl Ransomware might help you stay away from them the next time. Our researchers at Anti-spyware-101.com say that launchers containing such malicious applications often arrive with Spam emails or data downloaded from untrustworthy file-sharing websites. All it might take for the ransomware to settle in is to open an infected file that carries it. In many cases, users do not realize what is happening as they launch such data because such threats can hide their presence until all targeted files get encrypted.
If you do not want to be tricked into opening harmful files containing threats like Karl Ransomware, you should always be on guard. Whenever you receive a file you were not expecting to get or something that comes from an unreliable or unknown source, you should scan it with a legitimate antimalware tool that could examine it. If the file in question appears to be malicious, your security tool should help you get rid of it. Of course, if you want to avoid malware, you should keep away from websites and emails that could contain malicious data.
How does Karl Ransomware work?
Karl Ransomware was programmed to encrypt specific files. To our knowledge, the malware ought to lock files that could be valuable to their owners like photos or various documents. To separate encrypted files from unaffected data, the malicious application appends the .karl extension. For instance, once encrypted, a file called text.docx would become text.docx.karl. Soon after locking files, the threat should reveal itself by creating a ransom note called _readme.txt. The document should show a message that starts with: “ATTENTION! Don't worry, you can return all your files!”
The rest of the ransom note’s message explains how a user can contact Karl Ransomware’s developers and how to pay a ransom to receive a decryptor. The requested sum is $980 in full and $490, with a 50 percent discount that is given to those who pay in 72 hours after getting their devices infected. The note may also say that hackers can decrypt one file for free as a guarantee. In reality, such an offer may only confirm that cybercriminals have the decryptor, but it does not guarantee that such a tool will be sent to those who pay the ransom. Cybercriminals might forget about you once they receive a payment or could decide they want more money. Unfortunately, it is impossible to tell if they mean to keep up with their promises.
