Osiris.dll: What you should be aware of

Ransomware is a dreadful virus. This type of online blackmail has been around for a while, but in recent years it has turned into a top online threat and the malware of choice for cybercriminals and there are some good reasons for that. It gains enormous profit for its creators, who extort money from innocent online users by encrypting their PC’s data and asking them to pay huge amounts of money to decrypt it. As one of the latest developed representatives, Osiris.dll is packed with a full arsenal of delusive infection techniques and a strong encrypting algorithm, which ensures that this malware can do its malicious job best.

The infection process…

Basically, anyone can get infected with such Ransomware, and no one is immune to it. Nowadays, hackers have become so creative that they spread threats like Osiris.dll in ways and places where least expected. Usually, they use spam emails with attachments, fake ads, torrents, apps, misleading links and compromised websites that hide Trojan horse infections. A single careless click from the users is enough to activate the Trojan, which helps the Ransomware silently sneak in and immediately get down to its dirty business. Once inside, the Ransomware starts to infiltrate the infected system for targeted file types such as images, music, videos, documents, projects and all sorts of commonly used data, found on the hard drives and shared networks. Then it starts to encrypt them one by one by applying a very complex algorithm of symbols, which is almost unbreakable. Unfortunately, thanks to the coverage of the Trojan, it is very hard to detect what malicious activity is silently happening in the background until the encryption process is completed. A ransom note appears on the screen of the victim once all the files are locked and there the hackers place their ransom demands, deadlines and payment instructions.

Think again before you decide to pay – you may only burn your money

When it comes to Ransomware, we need to warn you that paying the ransom looks like the quickest option to get back your encrypted files, however, it is often a trap that the hackers want you to fall in. Their only goal is to take your money and as typical criminals, they often fade away once they receive the ransom payment, leaving you alone with your misery, empty pockets, and encrypted files. Moreover, by paying the ransom, you submit to their demands and “sponsor” their Ransomware “business model” to become more and more popular. If you don’t want to give your money to some unscrupulous hackers, you always have the option to remove the malware yourself and try to restore your files by other means. In the guide below we will show you all the possible options to do that. It is created with the sole idea to help you identify and completely delete the Ransomware and all its remains from your computer. We have also included some steps, which may help you recover the encrypted files. However, keep in mind that Osiris.dll is a very sophisticated threat and its harmful encryption may not be reversible without the proper decryption key. And while we cannot guarantee that the restoration process will work 100%, it is still worth trying all possible options. If you have some backups on an external drive or a cloud, it would be easier to recover from the data loss. But not before you completely clean your system from Osiris.dll.
